How to query in bpm to generate next seq key

Question

Hi,
I am working in 5.7 and DB2, I am able to insert a record in a table using Fuego.Sql.SqlObject.store() provided i assign the primary key value
prmary key needs to be generated using 'SELECT NEXT VALUE FOR BPMPR.BPM_KEY_SEQ FROM SYSIBM.SYSDUMMY1'
This query returns the next seq number outside bpm. but when i use it with in bpm, it complains : Unexpected value
Suggest me how to get the sequence key which is returned by 'SELECT NEXT VALUE FOR BPMPR.BPM_KEY_SEQ FROM SYSIBM.SYSDUMMY1' query.
I cannot use 'SELECT max(rqstKey) as nxtrqstKey FROM BPMPR.TABLE' to get the primary key value
Thanks!

Hi
The first thing you might want to try is to change your logic in ALBPM to use Dynamic SQL to run your query.
Here's the syntax that might work. The logic below assumes you named your database External Resouce "DbWithTheMostest".
nextId as String[]
query as String = "SELECT NEXT VALUE as nxtRqstKey FOR BPMPR.BPM_KEY_SEQ FROM SYSIBM.SYSDUMMY1"
externalResourceName as String = "DbWithTheMostest"
for each row in executeQuery(DynamicSQL, sentence : query, implname : externalResourceName) do
// keep adding customer names to the array until all the customers have been added
nextId[] = " " + row["nxtRqstKey "]
end
The second thing you might want to try is to catalog an SQL Query (vs. SQL). During the introspection, you'll be prompted to enter your sql.
Hope this helps,
