I use Hibernate and JpaRepository to handle my DB operations.
I have this query (to simplify because original query is quite big):
#Query(value="select * from history h where h.project_id in :projects", nativeQuery=true)
List<History> getHistoriesByProjectsIn(#Param("projects")List<Long> projects);
and it is working when I pass valid and not empty List<Long>. However when I pass empty list which may happen and it is not unusual in my scenario I get:
org.postgresql.util.PSQLException: ERROR: syntax error at or near ")"
Can anyone give me a hint on how to get rid of it?
The postgresql documentation states: in predicate can not hold empty list
expression IN (value [, ...])
and as hibernate passes the native queries as is, it's predictable that this leads to a problem.
But as workaround you can follow this suggestion: initialize the list with an impossible value.
EDIT
Actually, this behaviour was changed in hibernate 5.4.10. See the commit:
SHA-1: ab9ae431858dc6727023d7f03bd6925f99011c62
* HHH-8901 replace "in ()" SQL with "in (null)" in QueryParameterBindingsImpl
And for your case the following sql will be generated:
select * from history h where h.project_id in (null)
It looks strange that the task HHH-8901 description completely irrelevant to these changes.
I have a requirement of inserting greek characters, such as 'ϕ', into Oracle. My existing DB structure wasn't supporting it. On investigating found various solutions and I adopted the solution of using NCLOB instead of CLOB. It works perfectly fine when I use unicode, 03A6, for 'ϕ', and use UNISTR function in SQL editor to insert. Like the one below.
UPDATE config set CLOB = UNISTR('\03A6')
However, it fails when I try to insert the character through my application, using hibernate. On debugging, I find that the string before inserting is '\u03A6'. After insert, I see it as ¿.
Can some one please help me how I can resolve this? How do I make use of UNISTR?
PN: I don't use any native sqls or hqls. I use entity object of the table.
Edit:
Hibernate version used is 3.5.6. Cannot change the version as there are so many other plugins dependent on this. Thus, cannot use #Nationalized or #Type(type="org.hibernate.type.NClobType") on my field in Hibernate Entity
After racking my brain on different articles and trying so many options, I finally decided to tweak my code a bit to handle this in Java and not through hibernate or Oracle DB.
Before inserting into the DB, I identify unicode characters in the string and format it to append &#x in the beginning and ; at the end. This encoded string will be displayed with its actual unicode in the UI (JSP, HTML) that is UTF-8 compliant. Below is the code.
Formatter formatter = new Formatter();
for (char c : text.toCharArray()) {
if (CharUtils.isAscii(c)) {
formatter.format("%c", c);
} else {
formatter.format("&#x%04x;", (int) c);
}
}
String result = formatter.toString();
Ex:
String test = "ABC \uf06c DEF \uf06cGHI";
will be formatted to
test = "ABC DEF GHI";
This string when rendered in UI (and even in word doc) it displays it as
ABC DEF GHI
I tried it with various unicode characters and it works fine.
I am trying to use Dapper.net with Oracle.
From this post i understood that we could use parameters with no prefixes and dapper would then work for both sql serverand oracle
I'm having a hard time making it to work without the explicit oracle named parameters prefix :
The following query
sqlConnection.Query("Select * FROM document WHERE id = param1", new { param1 = 963 });
Throws ORA-00904: "PARAM1": invalid identifier
If i try with the # prefix it throws ORA-00936: missing expression
If i use the : prefix it works as expected. But i do not want my queries to be dependent (as far as possible) upon Oracle or Sql Server.
I am using the latest nuget package version Dapper.dll 1.12.1.1
What am I doing wrong or did i misunderstand this post?
Yes, you misunderstood the post. The SQL is passed through as-is, and must contain the correct :param1 or #param1 etc. The "no prefix at all" is talking about the code that you don't see - specifically, making sure that the code does (via some mechanism):
cmd.Parameters.Add("param1", 963);
vs
cmd.Parameters.Add("#param1", 963);
vs
cmd.Parameters.Add(":param1", 963);
The first (no prefix) is the correct and preferred option.
If you want the SQL in your code to be parameter agnostic, you could use the information from here: Get the parameter prefix in ADO.NET
The SQL is rarely close enough, however, that just looking up the parameter prefix will fix all problems.
I am using $expand to enhance an OData SharePoint REST query, and I would like to $filter on one of the properties of the expanded entity. However, I can't find any documentation on the correct syntax for this. I've found a few spots that might suggest using Entity/property, but after trying that, I fail with:
Query:
_vti_bin/listdata.svc/Posts?$expand=Category&$filter=substring(\"Featured Article\",Category/Title) eq false and year(Published) lt " +year+1+ " and month(Published) lt " +month+1+ " or day(Published) lt " +day+1+ " and ApprovalStatus eq '0'&$select=Title,Published,Category,ApprovalStatus&$orderby=Published desc"
Which returns:
syntax error '\"' at position 10.
How would I filter based on the Title of the Category entity, when Category is a high level, and it's Title property is a sub-level?
The filter on navigation entities is independent of the expand.
If the navigation property is a not collection (1:1 relation)
You can filter with type/property, here is an example to search for all orders that are made by customers with some id:
http://services.odata.org/V2/Northwind/Northwind.svc/Orders?$filter=Customer/CustomerID%20eq%20%27ANATR%27
If the navigation property is a collection (1:N relation):
OData Version 2: when the expanded entity is an entity collection, you cannot search on both the expanded and the target entity. For example you cannot do that query http://services.odata.org/V4/Northwind/Northwind.svc/Customers?$expand=Orders&$filter=Orders/ShipCity%20eq%20%27Berlin%27
A work around might be to flip the query (to selecting the orders instead of customers - each order has 1 cutomer):
http://services.odata.org/V2/Northwind/Northwind.svc/Orders?$filter=ShipCity%20eq%20%27Berlin%27&$expand=Customer
but then you could get duplicate customers (your actual target entity).
OData Version 3 You might consider to use a custom query option (http://www.odata.org/documentation/odata-version-3-0/url-conventions/).
OData Version 4: you can do a filter with the any construct:
http://services.odata.org/V4/Northwind/Northwind.svc/Customers?$filter=Country%20eq%20%27Germany%27%20and%20Orders/any(o:o/ShipCity%20eq%20%27Berlin%27)
It looks like the problem is the slash-escaped double quote and that you're using substring instead of substringof.
Does it work if you use single quotes instead? Or did you want to literally match the double-quote character? (If that's the case, I think you can just leave the double quote unescaped inside the single quotes)
_vti_bin/listdata.svc/Posts?$expand=Category&$filter=substringof('Featured Article',Category/Title) eq false
or
_vti_bin/listdata.svc/Posts?$expand=Category&$filter=substringof('"Featured Article"',Category/Title) eq false
As an example on a public service, take a look at this query:
http://services.odata.org/Northwind/Northwind.svc/Products?$filter=substringof('Bev', Category/CategoryName) eq true
As far as documentation for the OData query syntax, I recommend taking a look at this page: http://www.odata.org/documentation/odata-v3-documentation/url-conventions
In the filter section there are a fair number of examples you can use for guidance.
Query's throwing an ORA-00907 Error when I try to paste a list of values into a criteria.
Background: I'm not a developer, I'm just an end user that's studied enough to where I can write queries using PS/Query within Peoplesoft,
for my company's implementation. I work with Peoplesoft's FSCM module
(Financials and Supply Chain Management), currently on Version FSCM
8.90.08.024, using I think Oracle 11g as the base database.
I'm mostly self-taught, and the technical experts we have are busy
with database/application stuff, or they aren't familiar with my
section's specific data needs.
I should point out that I'm unable to directly write SQL statements to
Query the database. I have to use a built-in program called "PS/Query"
(also known as Query Manager) with a GUI that writes the SQL for you
and saves it as a Query that you can run to the database to extract
data. This is relevant to my question only in that:
1. I cannot create or alter views/tables
2. I cannot perform any type of SQL Statement except "SELECT"
3. I can embed PL/SQL, MetaSQL and plain SQL into Expressions
4. At this point, Query Manager is the only option I have.
PS/Query is my only experience with SQL so far, aside from Oracle's
documentation and sites like this. From my research, it's considered
extremely confining by "actual" SQL programmers.The restrictions on it
require you to do things in a manner that violates what seem to be
best practices of SQL coding.
Query Request: I have a query I've been requested to write that pulls out spend (on Vouchers and POs) against certain system-defined
Category Codes. What I'm trying to do is pull in Voucher IDs, sum the
merchandise amounts on them by Vendor and Category Code, and display
the results. Or in other words, for every unique combination of
Vendor/Category, add up all the Voucher Amounts that have that
Vendor/Category combination.
Using the SUM (Fieldname) OVER (PARTITION BY fieldname, fieldname)
syntax.
So the end result should look something like...
Code Vendor Amount
123-45 Acme $5000.00
123-45 Apple $4200.00
123-46 Acme $750.00
With that said, here's the SQL that Query Manager is displaying to get the result set I showed above:
SELECT DISTINCT D.CATEGORY_CD, D.TN_DESCR1000, C.VENDOR_ID, E.NAME1, SUM ( A.MERCH_AMT_VCHR) OVER (PARTITION BY D.CATEGORY_CD, C.VENDOR_ID),E.SETID,E.VENDOR_ID
FROM PS_PO_LINE_MATCHED A, PS_PO_LINE B, PS_PO_HDR C, PS_ITM_CAT_TBL D, PS_VENDOR E, PS_PYMNT_VCHR_XREF F
WHERE A.BUSINESS_UNIT = B.BUSINESS_UNIT
AND A.PO_ID = B.PO_ID
AND A.LINE_NBR = B.LINE_NBR
AND B.BUSINESS_UNIT = C.BUSINESS_UNIT
AND B.PO_ID = C.PO_ID
AND D.CATEGORY_ID = B.CATEGORY_ID
AND D.EFFDT =
(SELECT MAX(D_ED.EFFDT) FROM PS_ITM_CAT_TBL D_ED
WHERE D.SETID = D_ED.SETID
AND D.CATEGORY_TYPE = D_ED.CATEGORY_TYPE
AND D.CATEGORY_CD = D_ED.CATEGORY_CD
AND D.CATEGORY_ID = D_ED.CATEGORY_ID
AND D_ED.EFFDT <= SYSDATE)
AND ( F.SCHEDULED_PAY_DT >= TO_DATE('2010-07-01','YYYY-MM-DD')
AND F.SCHEDULED_PAY_DT <= TO_DATE('2011-06-30','YYYY-MM-DD'))
AND D.CATEGORY_CD LIKE :1
AND E.VENDOR_ID = C.VENDOR_ID
AND A.BUSINESS_UNIT = F.BUSINESS_UNIT
AND A.VOUCHER_ID = F.VOUCHER_ID
ORDER BY 1
Underlying Issue: This works fine, but it can only prompt on one
Category Code at a time. Category Codes are 5 digits, a 3-digit
"Class" followed by a dash and then a 2-digit "subclass. I have a list
of 375 Category Codes I need to get this Query result for.
I've set up a prompt on this version that allows entry of a Wildcard
(So 123-%%), but that's still about a hundred separate runs of the
Query. Query Manager allows use of an "In List" expression type in
Criteria, but it requires you to manually enter each entry in the
list.
I'm trying to set it up to where I can paste a plaintext copy of the
Code list into an Expression, with proper quotes/commas, and have it
evaluate that to give me a combined list of all the NIGP codes
specified. The Prompt field created by Query Manager doesn't allow
pasting of lists (as far as I know).
Attempted Solution: I viewed the page at http://peoplesoft.ittoolbox.com/groups/technical-functional/peoplesoft-other-l/create-an-expression-in-psoft-90-query-to-paste-a-list-of-emplids-2808427 and I've tried some of the answers given there, but none of them worked. That page led to me trying this modified SQL (obviously the list of codes is truncated a bit for display here):
SELECT DISTINCT D.CATEGORY_CD, D.TN_DESCR1000, C.VENDOR_ID, E.NAME1, SUM ( A.MERCH_AMT_VCHR) OVER (PARTITION BY D.CATEGORY_CD, C.VENDOR_ID),E.SETID,E.VENDOR_ID
FROM PS_PO_LINE_MATCHED A, PS_PO_LINE B, PS_PO_HDR C, PS_ITM_CAT_TBL D, PS_VENDOR E, PS_PYMNT_VCHR_XREF F
WHERE A.BUSINESS_UNIT = B.BUSINESS_UNIT
AND A.PO_ID = B.PO_ID
AND A.LINE_NBR = B.LINE_NBR
AND B.BUSINESS_UNIT = C.BUSINESS_UNIT
AND B.PO_ID = C.PO_ID
AND D.CATEGORY_ID = B.CATEGORY_ID
AND D.EFFDT =
(SELECT MAX(D_ED.EFFDT) FROM PS_ITM_CAT_TBL D_ED
WHERE D.SETID = D_ED.SETID
AND D.CATEGORY_TYPE = D_ED.CATEGORY_TYPE
AND D.CATEGORY_CD = D_ED.CATEGORY_CD
AND D.CATEGORY_ID = D_ED.CATEGORY_ID
AND D_ED.EFFDT <= SYSDATE)
AND ( F.SCHEDULED_PAY_DT >= TO_DATE('2010-07-01','YYYY-MM-DD')
AND F.SCHEDULED_PAY_DT <= TO_DATE('2011-06-30','YYYY-MM-DD'))
AND D.CATEGORY_CD = '005-00' OR D.CATEGORY_CD IN ('015-00,'' '015-06,'' '015-10,'' '615-07'')
AND E.VENDOR_ID = C.VENDOR_ID
AND A.BUSINESS_UNIT = F.BUSINESS_UNIT
AND A.VOUCHER_ID = F.VOUCHER_ID
ORDER BY 1
And the SQL above is what's giving me the ORA-00907 error. Has anyone ran into this problem before? Massive wall of text, I know. My apologies. This is my first post here and I'm trying not to leave anything relevant out.
I've got the immediate problem that spurred this question fixed,but that request is just the tip of a very large iceberg, and at some point I need to figure out a way to be able to paste plaintext lists in as criteria using Query Manager, preferably in a way that plays nice with Analytic Grouping.
TL;DR version:
Using Peoplesoft Query Manager to do an Analytic SUM with grouping using OVER, PARTITION BY. When I try to paste a list into the criteria, it throws an ORA-00907 Error.
Any help would be greatly appreciated. Thanks!
Ok, after a bit more tweaking with this, I've found what I think is the underlying issue.
The error, in this case, is two-fold. Part of it was my fault (I didn't check for Peoplesoft mangling the quotation marks I pulled from Word), and part of it was the way Query Manager interprets some kinds of functions (you have to wrap some stuff in a Case When statement to get it to evaluate properly).
First, the "My Fault" part:
Every time I was pasting in my list of test NIGP Codes, I was doing it from a file I kept saved in Microsoft Word.
Which has the probably-handy "replace straight quotes with smart quotes" feature. Peoplesoft goes bonkers when its presented a "smart quote", and will display them as upside-down question marks (there's probably a technical term, I don't know it).
So when I'd test suggestions (such as fixing the quote/comma order as suggested by #Rene Nyffenegger and #WayneH) I'd start with my base test query, add in the expressions and test it, saving it as a separate query. If they didn't work, I'd go back to the base query. That way I could iterate changes and save potential tests as different versions.
My mistake was in not saving the different versions, leaving the application and going back in. It's when you save the query, leave the page, go somewhere else in Peoplesoft, then go back to open Query Manager that it actually shows you that it's doing the character conversion. You can't see it unless you do that. Even though Query Manager is doing it. So it was throwing a character Query Manager wouldn't recognize, but not showing me the character it wouldn't recognize.
I got a new work PC recently, and I've now disabled the Smart Quotes auto-replace for future use.
Second, the "Query Manager: part:
On the version of this that I got to work, I made use of wrapping the "IN" function inside a Case statement. I've found that a lot of SQL functions, when used "plain" (as I'd define them by just copy-pasting from Oracle's definitions pages and filling in the appropriate variables) tend to give PS/Query (Query Manager) heartburn. But if you wrap them inside a CASE...WHEN...END statement that evaluates the result of the function and then build a criteria that selects based on certain values of that result, the function will work and properly display a result.
So for an example, set up this expression (like in the example from #qyb2zm302). I'm using different codes from what was in my original example, but they work the same (they're all five-digit, character-typed codes consisting of three digits, a dash, then two digits)
Case when E.CATEGORY_CD IN
('375-15', '375-30', '375-54', '375-60', '380-30','938-63')
then 'true'
else 'false'
end
And then set a criteria:
AND
Case when E.CATEGORY_CD IN
('375-15', '375-30', '375-54', '375-60', '380-30','938-63')
then 'true'
else 'false'
end
= 'true'
It'll run to completion and return any rows that have that Category Code.
If you don't want to do that, you can do like in #qyb2zm302's Method 2. The only downside to that in Query Manager is that you have to enter them into individual rows in the "List", and if you can only copy-paste 25 at a time.
Wrapping it in a Case Statement lets you paste it directly into an Expression, which is far better for larger lists.
Solutions:
The above is the code I went with that worked. It's simplifying a bit for brevity's sake, but it works.
In List works through the native Query Manager option as long as you manually-populate the list
D.CATEGORY_CD = '005-00' OR works as long as you wrap it in a Case Statement
D.CATEGORY_CD IN ('015-00','015-06','015-10','615-07') works as long as you wrap it in a Case Statement
Peoplesoft hates Smart Quotes. None of the above will work if you're copying quotation marks directly from Word, but you won't see it unless you save, leave and come back to the same query in edit mode
Formatting is important. All of the above require the proper comma/quotation formatting, as pointed out by Rene and Wayne. Meaning: ('xxx-xx', 'xxx-01','xxx-02') etc
Thanks to everyone who helped on this! I don't think I've head-desked this hard before on any question, but I guess that's part of the learning process. Since all the answers posted are valid and correct (or at least a portion of the larger "correct"), I'm going to flag them all.
The
D.CATEGORY_CD IN ('015-00,'' '015-06,'' '015-10,'' '615-07'')
part looks fishy to me
Since a '' within a string "evaluates" to a single ' the first string is
'015-00,'' '
followed by (the non-string)
015-06,
The following '' is probably the thing that the parser stumbles upon since it's pretty meaningless.
Edit try it with a D.CATEGORY_CD IN ('015-00', '015-06', '015-10', '615-07').
Following the link you posted, I see 2 methods for doing what you are trying to accomplish.
I also notice that you tried a 3rd method.
Method 1
Criteria > Add Criteria
Expression Type: Character
Length: 255
Expression Text: D.CATEGORY_CD IN ('015-00','015-06','015-10','615-07') AND 1
Condition Type: equal to
Constant: 1
Method 2
Criteria > Add Criteria
Field: D.CATEGORY_CD
Condition Type: in list
Value: 015-00','015-06','015-10','615-07
Method 3 (Your Method)
Criteria > Add Criteria
Field: D.CATEGORY_CD
Condition Type: equal to
Define Expression: '015-00' OR D.CATEGORY_CD IN ('015-00','015-06','015-10','615-07')
Question) Does the below exactly match the text you are putting the Expression box?
'015-00' OR D.CATEGORY_CD IN ('015-00','015-06','015-10','615-07')
If not, what are you putting in that box?
I think the D.CATEGORY_CD criteria are giving you the problems, I changed the double quotes to single quotes and then it still looked strange to me. I then notice the commas are inside your quotes and not between them, try making the one criteria line look like this:
before:
OR D.CATEGORY_CD IN ('015-00,'' '015-06,'' '015-10,'' '615-07'')
after:
OR D.CATEGORY_CD IN ('015-00', '015-06', '015-10', '615-07')
Also, the "IN" is an implied "OR" and I am not sure if you have parenthesis around the two D.CATEGORY_CD,
I would just put the one additional code into the IN criteria and remove the "D.CATEGORY_CD =" line:
before:
AND D.CATEGORY_CD = '005-00' OR D.CATEGORY_CD IN ('015-00', '015-06', '015-10', '615-07')
after:
AND D.CATEGORY_CD IN ('015-00', '015-06', '015-10', '615-07', '005-00')
Of course, you are already ordering by CATEGORY_CD, you could remove this criteria and pull all categories in one run (that is unless there are too many rows for excel), and then you might also want to include either VENDOR_ID or NAME1 in the ORDER BY clause.
Hope that helps you.
