Hello!
I have a problem connected with querying HANA calculation view from ABAP.
I generate the SQL statement in ABAP, send it to HANA and get query results.
The SQL statement that I generate in ABAP has to have a lot of distinct WHERE conditions consisting of four fields. The query looks like this:
SELECT fld1, fld2, fld3, fld4, fld5, fld6
FROM "_SYS_BIC"."packetname/CV_MY_VIEW"
WHERE (
(fld1 = 'val11' AND fld2 = 'val12' AND fld3 = 'val13' AND fld 4 = 'val14')
OR (fld1 = 'val21' AND fld2 = 'val22' AND fld3 = 'val23' AND fld 4 = 'val24')
OR (fld1 = 'val31' AND fld2 = 'val32' AND fld3 = 'val33' AND fld 4 = 'val34')
.
.
.
.
)
When there are less than 83 conditions in WHERE clause, the view is executed by HANA in less than 1 second, returning ~3000 rows.
When there are 83 or more conditions, the execution of a query is hanging for a few minutes and then it drops down with error:
SAP DBTech JDBC: [2048]: column store error: search table error: [9] Memory allocation failed.
I've tried to run the same query from HANA Studio but I get the same error.
Could you please explain me, why is this happening?
Can I do something to be able to send, like, 1000 of conditions, or more, and get the correct result from HANA?
