I have a column with less than <50 comma separated values. And the number of comma separated values in that particular column is not constant I would like to query this table with IN/AND/OR clause for these comma separated values:
So I would like to:
split these values into separate columns in the select query
Query for a person's market code with AND, OR and IN :
EUP and APCAC
APAC or EU Or CA
IN ( APAC,EU,LATIM)
I have to use this query in spring data jpa native query
I don't want to use as many substr.
I thought to accomplish this by using connect by with level would be useful after referring the following answers - ans1 and ans2
Usertable:
username
market_code
in_use
john
eup,apac,Latim
0
sebastin
apac,Latim
0
xavier
ca,apac,Latim
0
However the following only returns one row where I expected to have 3 rows :
select regexp_substr(market_code,'[^|]+', 1, level) from testautomadm.userpool
where AND USERNAME = 'john'
connect by regexp_substr('market_code', '[^|]+', 1, level)
is not null
Any help to solve this use case much appreciated.
Thank you!
You can use the multiset and hierarchy query as follows:
Select user_name,
listagg(market_code, ',') within group (order by pos) as market_code,
In_use
From
(Select user_name,
regexp_substr(market_code, '[^,]+',1, column_value) as market_code,
in_use,
column_value as pos
From t,
table(cast(multiset(
select level from dual
connect by level <= length (regexp_replace(t.market_code, '[^,]+')) + 1
) as sys.OdciNumberList)) levels) t
Where market_code in ('EUP','APCAC')
Group by user_name, in_use
Having count(distinct market_code) = 2
Above query shows the usage of AND as we have used count = 2 You can use count = 1 and respective market_code in IN for OR And IN query

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?

group by t1.name;

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 using APEX 20.2.
I have a checkbox group with 3 different values:
The values checked in this group are used to filter a query and I'm not sure how to write the where clause
Here is what I have:
SELECT Null as link, PERSONNE_EN_CHARGE as label, count(*) as value
FROM FLYWAY_MEP_HISTORY
WHERE STATUT_MEP='SUCCESS'
AND (DATE_MEP BETWEEN to_date(:DATE_DEBUT,'DD/MM/YYYY') AND to_date(:DATE_FIN ,'DD/MM/YYYY')+1)
OR (:DATE_DEBUT is null and :DATE_FIN is null)
AND (UPPER(ENVIRONNEMENT) is null or UPPER(ENVIRONNEMENT) IN (:ENVIRONNEMENT))
GROUP BY PERSONNE_EN_CHARGE
ORDER BY 2;
the part I'm not sure of is this part:
UPPER(ENVIRONNEMENT) IN (:ENVIRONNEMENT))
How can I use the values of the checkbox group in the where clause?
If I debug the page I can see this in the devlopper console
When you select multiple values in Apex, they are separated by colon. So, if you split that value into rows, you can use it as a subquery. In your case:
...
or UPPER(ENVIRONNEMENT) IN
(select regexp_substr(:ENVIRONNEMENT, '[^:]+', 1, level)
from dual
connect by level <= regexp_count(:ENVIRONMENT, ':') + 1
)
I have a query that gets contract_types 1 to 10. This query is being used in an SSRS report to filter out a larger dataset. I am using -1 for nulls and -2 for all.
I would like to know how we would allow multiple values - does oracle concatenate the inputs together so '1,2,3' would be passed in? Say we get select -1,0,1 in SSRS, how could we alter the bottom query to return values?
My query to get ContractTypes:
SELECT
ContractType,
CASE WHEN ContractType = -2 THEN 'All'
WHEN ContractType = -1 THEN'Null'
ELSE to_Char(ContractType)
END AS DisplayFigure
FROM ContractTypes
which returns
ContractType DisplayFig
-1 Null
0 0
1 1
2 2
3 3
4 4
5 5
6 6
7 7
8 8
9 9
10 10
This currently is only returning single values or all, not muliple values:
SELECT *
FROM Employee
WHERE NVL(CONTRACT_TYPE, -1) = :contract_type or :contract_type = -2
I'm assuming we want to do something like:
WHERE NVL(CONTRACT_TYPE, -1) IN (:contract_type)
But this doesn't seem to work.
Data in Employee
Name ContractType
Bob 1
Sue 0
Bill Null
Joe 2
In my report, I want to be able to select contract_type as -1(null),0,1 using the 'allow muliple values' checkbox. At the moment, I can only select either 'all' using my -2 value, or single contract types.
My input would be: contract type = -1,1,2
My output would be Bill, Bob, Joe.
This is how I'm executing my code
I use SSRS with Oracle a lot so I see where you're coming from. Thankfully, they work pretty well together.
First make sure the parameter is set to allow multiple values. This adds a Select All option to your dropdown so you don't have to worry about adding a special case for "All". You'll want to make sure the dataset for the parameter has a row with -1 as the Value and a friendly description for the Label.
Next, the WHERE clause would be just as you mentioned:
WHERE NVL(CONTRACT_TYPE, -1) IN (:contract_type)
SSRS automatically populates the values. There is no XML or string manipulation needed. Keep in mind that this will not work with single-value parameters.
If for some reason this still doesn't work as expected in your environment, there is another workaround you can use which is more universal and works even with ODBC connections.
In the dataset parameter properties, use an expression like this to concatenate the values into a single, comma-separated string:
="," + Join(Parameters!Parameter.Value, ",") + ","
Then use an expression like this in your WHERE clause:
where :parameter like '%,' + Column + ',%'
Obviously, this is less efficient because it most likely won't be using an index, but it works.
I don't know SSRS, but - if I understood you correctly, you'll have to split that comma-separated values list into rows. Something like in this example:
SQL> select *
2 from dept
3 where deptno in (select regexp_substr('&&contract_type', '[^,]+', 1, level)
4 from dual
5 connect by level <= regexp_count('&&contract_type', ',') + 1
6 );
Enter value for contract_type: 10,20,40
DEPTNO DNAME LOC
---------- -------------------- --------------------
20 RESEARCH DALLAS
10 ACCOUNTING NEW YORK
40 OPERATIONS BOSTON
SQL>
Applied to your code:
select *
from employee
where nvl(contract_type, -1) in (select regexp_substr(:contract_type, '[^,]+', 1, level)
from dual
connect by level <= regexp_substr(:contract_type, ',') + 1
)
If you have the comma separated list of numbers and then if you like to split it then, the below seems simple and easy to maintain.
select to_number(column_value) from xmltable(:val);
Inputs: 1,2,3,4
Output:
I guess I understood your problem. If I am correct the below should solve your problem:
with inputs(Name, ContractType) as
(
select 'Bob', 1 from dual union all
select 'Sue', 0 from dual union all
select 'Bill', Null from dual union all
select 'Joe', 2 from dual
)
select *
from inputs
where decode(:ContractType,'-2',-2,nvl(ContractType,-1)) in (select to_number(column_value) from xmltable(:ContractType))
Inputs: -1,1,2
Output:
Inputs: -2
Output:
I have a column named voucher_number. The data in this column looks like
1, 2
I want a query (in oracle and linq as well) to return 0,3,4,5,6,7,8,9,10
Note: i am taking range (0 to 10 )as a parameter parameter from screen(aspx page)
You can use MINUS operator as following:
Select voucher_num from
(
(Select level - 1 as voucher_num from dual
Connect by level <= 11)
Minus
(Select voucher_number from your_table)
)
Order by voucher_num;
Cheers!!
I'm new to Oracle and recently ran into the following query. I'm trying to understand what it's doing and hopefully rewrite it to optimize it. In this example, :NameList would be a comma separated list (like: "Bob,Bill,Fred") and then :N_NameList would be the number of tokens (in above example, 3)
SELECT ... FROM
(
SELECT
REGEXP_SUBSTR(:NameList,'[^,]+',1,LEVEL, 'i') Name
FROM DUAL CONNECT BY LEVEL <= :N_NameList
) x
INNER JOIN PEOPLE ppl
ON ppl.Name LIKE x.Name
...
From what I can tell, it expands out the delimited list into unique rows and then joins it with the following tables for each name, but I'm not sure if that's all it's doing. If that is the case, is there a better way to accomplish this?
You could try this instead:
select ...
from people ppl
where instr (','||:NameList||',',
','||ppl.name||',') > 0;
is there a better way to accomplish this?
Well, you could get rid of N_NameList because you can easily count number of tokens. This doesn't mean that it is a better way, it's just a different option. To be honest, it is probably slower option than yours as I have to calculate something that you entered as a parameter.
As this example is based on SQLPlus, I've used & instead of : for substitution variables. && means that it'll "remember" previously entered value (otherwise, I should type NameList twice.
Your current query:
SQL> select regexp_substr('&namelist', '[^,]+', 1, level, 'i') name
2 from dual
3 connect by level <= &n_namelist;
Enter value for namelist: Bob,Bill,Fred
Enter value for n_namelist: 3
Bob
Bill
Fred
Calculated N_NameList (using REGEXP_COUNT):
SQL> select regexp_substr('&&namelist', '[^,]+', 1, level, 'i') name
2 from dual
3 connect by level <= regexp_count('&&namelist', ',') + 1;
Enter value for namelist: Bob,Bill,Fred
Bob
Bill
Fred
