I am facing an error while incorporating an Oracle query in a SSRS report.
The below mentioned query is supposed to give output from a table TABLE1 on the basis of values selected for twofilters for VAR1 and VAR2. VAR1 must be selected by the user. VAR2(i.e. a date field) by default will show all the results. VAR2 will show results for a particular date if that is selected by the user.
Plesae note that this query runs just fine in Oracle. However, when I execute this code in SSRS, it throws the below mentioned error: "ORA-00920: invalid relational operator"
Would really appreciate any help here.
Select Distinct
VAR1,
VAR2,
AMT_FIELD
From TABLE1 SPF
Where VAR1 = (:prm1)
And (CASE
WHEN ((:PRM2) IS NOT NULL AND VAR2 = (:PRM2)) THEN 1
WHEN ((:PRM2) IS NULL AND VAR2 >= (SELECT min(VAR2) FROM TABLE1 NI Where NI.VAR1 = (:prm1))) THEN 1
ELSE 0
END) = 1 ;
Thanks

I have a program that has been working for years. Today, we upgraded from SAS 9.4M3 to 9.4M7.
proc setinit
Current version: 9.04.01M7P080520
Since then, I am not able to get the same results as before the upgrade.
Please note that I am querying on Oracle databases directly.
Trying to replicate the issue with a minimal, reproducible SAS table example, I found that the issue disappear when querying on a SAS table instead of on Oracle databases.
Let's say I have the following dataset:
data have;
infile datalines delimiter="|";
input name :$8. id $1. value :$8. t1 :$10.;
datalines;
Joe|A|TLO
Joe|B|IKSK
Joe|C|Yes
;
Using the temporary table:
proc sql;
create table want as
select name,
min(case when id = "A" then value else "" end) as A length 8
from have
group by name;
quit;
Results:
name A
Joe TLO
However, when running the very same query on the oracle database directly I get a missing value instead:
proc sql;
create table want as
select name,
min(case when id = "A" then value else "" end) as A length 8
from have_oracle
group by name;
quit;
name A
Joe
As per documentation, the min() function is behaving properly when used on the SAS table
The MIN function returns a missing value (.) only if all arguments are missing.
I believe this happens when Oracle don't understand the function that SAS is passing it - the min functions in SAS and Oracle are very different and the equivalent in SAS would be LEAST().
So my guess is that the upgrade messed up how is translates the SAS min function to Oracle, but it remains a guess. Does anyone ran into this type of behavior?

From the prepared statement you can see why you are getting a blank from the Oracle query.
select
t1."NAME"
, MIN ( case
when t2."ID" = 'A' then t1."VALUE"
else ' '
end
) as A
from
NAMES t1 inner join IDS t2 on t1."TID" = t2."TID"
group by
t1."NAME"
The SQL MIN () aggregate function will exclude null values from consideration.
In SAS SQL, a blank value is also interpreted as null.
In SAS your SQL query returns the min non-null value TLO
In Oracle transformed query, the SAS blank '' is transformed to ' ' a single blank character, which is not-null, and thus ' ' < 'TLO' and you get the blank result.
The actual MIN you want to force in Oracle is min(case when id = "A" then value else null end) which #Tom has shown is possible by omitting the else clause.
The only way to see the actual difference is to run the query with trace in the prior SAS version, or if lucky, see the explanation in the (ignored by many) "What's New" documents.
Why are you using ' ' or '' as the ELSE value? Perhaps Oracle is treating a string with blanks in it differently than a null string.
Why not use null in the ELSE clause?
or just leave off the ELSE clause and let it default to null?
libname mylib oracle .... ;
proc sql;
create table want as
select name
, min(case when id = "A" then value else null end) as A length 8
from mylib.have_oracle
group by name
;
quit;
Also try running the Oracle code yourself, instead of using implicit pass thru.
proc sql;
connect to oracle ..... ;
create table want as
select * from connection to oracle
(
select name,
min(case when id = "A" then value else null end) as A length 8
from have_oracle
group by name
)
;
quit;
When I try to reproduce this in Oracle I get the result you are looking for so I suspect it has something to do with SAS (which I'm not familiar with).
with t as (
select 'Joe' name, 'A' id, 'TLO' value from dual union all
select 'Joe' name, 'B' id, 'IKSK' value from dual union all
select 'Joe' name, 'C' id, 'Yes' value from dual
)
select name
, min(case when id = 'A' then value else '' end) as a
from t
group by name;
NAME A
---- ----
Joe TLO
Unrelated, if you are only interested in id = 'A' then a better query would be:
select name
, min(value) as a
from t
where id = 'A'
group by name;
i'm with a problem in a query.
I have a table called "store" that I need to query.
Select s.store_name
from store s
where s.store = case
when p_store != 0 then
p_store
else
s.store
end;
This should work but as I have "stores" with characters (-) in column and this is defined as number, that query raise an exception: ORA-01722: invalid number.
So I want to do something like this in query:
IF p_store != 0 then
select store_name from store where store = p_store
else
select store_name from store;
Is it possible?
Thanks!
EDIT:
The query that I wrote above was an example of the query I was running.
The exception was raised because another column (too much hours in front of PC :-( ).
This table have a column that's varchar2(15) and I was doing this condition:
(...)AND S.CODE > 4 (...)
The correct condition that I want to do is:
(...)AND LENGTH(S.CODE) > 4
Thank you all!
As far as I understand you have varchar2 s.store which in fact contains numbers so Oracle tries to compare it casting to numbers but at some point it gets - and throws an exception. What you should do is update on table replacing - by null. But if you don't want to do that you can try to make case return varchar2
Select s.store_name
from store s
where s.store = case
when to_char(p_store) != '0' then
to_char(p_store)
else
s.store
end;
I am guessing you are running the query in a plsql block (as cursor?). In that case dynamic sql is the way to go. check out REF CURSOR too (google!).
I need a query to return boolean when there's table has data in the given range.
Assume table
Customer
[User ID, Name, Date, Products_Purchased]
I'm trying to do:
select case when exists(
select Date, count(*)
from Customer
where date between '2015-08-03' and '2015-08-05'
)
then cast(1 as BIT)
else case(0 as BIT)end;
This is throwing an error near "select Date".
However, weird part is the inner query is running perfectly fine.
Im wondering if im missing out something here !
What about something more straightforward e.g.
select case when count(*) >0 then 1 else 0 end as HIT
from ... where ...
That way you don't have to bother about Hive assuming that EXISTS implies a correlated sub-query, automagically translated into a MapJoin, i.e. a Java HashMap shuffled to the 2nd line of Mappers jobs, etc. Not exactly your use case.
Then it's not useful to compute the exact count, so the query could be refined as
select case when count(*) >0 then 1 else 0 end as HIT
from
(select ... from ... where ... limit 1) X
[Edit] There is no "bit" datatype in Hive. But the default "int" should be OK if you just want a return flag (zero / non-zero)
A weird request maybe but. My boss wants me to create an admin version of a page we have that displays data from an oracle query in a table.
The admin page, instead of displaying the data (query returns 1 row), needs to return the table name and column name
Ex: Instead of:
Name Initial
==================
Bob A
I want:
Name Initial
============================
Users.FirstName Users.MiddleInitial
I realize I can do this in code but would rather just modify the query to return the data I want so I can leave the report generation code mostly alone.
I don't want to do it in a stored procedure.
So when I spit out the data in the report using something like:
blah blah = MyDataRow("FirstName")
I can leave that as is but instead of it displaying "BOB" it would display "Users.FirstName"
And I want to do the query using select * if possible instead of listing all the columns
So for each of the columns I am querying in the * , I want to get (instead of the column value) the tablename.ColumnName or tablename|columnName
hope you are following- I am confusing myself...
pseudo:
select tablename + '.' + Columnname as WhateverTheColumnNameIs
from Table1
left join Table2 on whatever...
Join Table_Names on blah blah
Whew- after writing all this I think I will just do it on the code side.
But if you are up for it maybe a fun challenge
Oracle does not provide an authentic way(there is no pseudocolumn) to get the column name of a table as a result of a query against that table. But you might consider these two approaches:
Extract column name from an xmltype, formed by passing cursor expression(your query) in the xmltable() function:
-- your table
with t1(first_name, middle_name) as(
select 1,2 from dual
), -- your query
t2 as(
select * -- col1 as "t1.col1"
--, col2 as "t1.col2"
--, col3 as "t1.col3"
from hr.t1
)
select *
from ( select q.object_value.getrootelement() as col_name
, rownum as rn
from xmltable('//*'
passing xmltype(cursor(select * from t2 where rownum = 1))
) q
where q.object_value.getrootelement() not in ('ROWSET', 'ROW')
)
pivot(
max(col_name) for rn in (1 as "name", 2 as "initial")
)
Result:
name initial
--------------- ---------------
FIRST_NAME MIDDLE_NAME
Note: In order for column names to be prefixed with table name, you need to list them
explicitly in the select list of a query and supply an alias, manually.
PL/SQL approach. Starting from Oracle 11g you could use dbms_sql() package and describe_columns() procedure specifically to get the name of columns in the cursor(your select).
This might be what you are looking for, try selecting from system views USER_TAB_COLS or ALL_TAB_COLS.
Question:
Is it possible to have a column name in a select statement changed based on a value in it's result set?
For example, if a year value in a result set is less than 1950, name the column OldYear, otherwise name the column NewYear. The year value in the result set is guaranteed to be the same for all records.
I'm thinking this is impossible, but here was my failed attempt to test the idea:
select 1 as
(case
when 2 = 1 then "name1";
when 1 = 1 then "name2")
from dual;
You can't vary a column name per row of a result set. This is basic to relational databases. The names of columns are part of the table "header" and a name applies to the column under it for all rows.
Re comment: OK, maybe the OP Americus means that the result is known to be exactly one row. But regardless, SQL has no syntax to support a dynamic column alias. Column aliases must be constant in a query.
Even dynamic SQL doesn't help, because you'd have to run the query twice. Once to get the value, and a second time to re-run the query with a different column alias.
The "correct" way to do this in SQL is to have both columns, and have the column that is inappropriate be NULL, such as:
SELECT
CASE WHEN year < 1950 THEN year ELSE NULL END AS OldYear,
CASE WHEN year >= 1950 THEN year ELSE NULL END AS NewYear
FROM some_table_with_years;
There is no good reason to change the column name dynamically - it's analogous to the name of a variable in procedural code - it's just a label that you might refer to later in your code, so you don't want it to change at runtime.
I'm guessing what you're really after is a way to format the output (e.g. for printing in a report) differently depending on the data. In that case I would generate the heading text as a separate column in the query, e.g.:
SELECT 1 AS mydata
,case
when 2 = 1 then 'name1'
when 1 = 1 then 'name2'
end AS myheader
FROM dual;
Then the calling procedure would take the values returned for mydata and myheader and format them for output as required.
You will need something similar to this:
select 'select ' || CASE WHEN YEAR<1950 THEN 'OLDYEAR' ELSE 'NEWYEAR' END || ' FROM TABLE 1' from TABLE_WITH_DATA
This solution requires that you launch SQLPLUS and a .sql file from a .bat file or using some other method with the appropriate Oracle credentials. The .bat file can be kicked off manually, from a server scheduled task, Control-M job, etc...
Output is a .csv file. This also requires that you replace all commas in the output with some other character or risk column/data mismatch in the output.
The trick is that your column headers and data are selected in two different SELECT statements.
It isn't perfect, but it does work, and it's the closest to standard Oracle SQL that I've found for a dynamic column header outside of a development environment. We use this extensively to generate recurring daily/weekly/monthly reports to users without resorting to a GUI. Output is saved to a shared network drive directory/Sharepoint.
