Here is an example of the SQL used to generate the SEQUENCE List report in RC/Query, note the WHERE clause uses CREATEDBY:
SELECT A.NAME, A.SCHEMA, A.OWNER, A.CREATEDBY, A.SEQTYPE, A.SEQUENCEID FROM SYSIBM.SYSSEQUENCES A WHERE A.CREATEDBY = 'Z1TM001$' ORDER BY A.NAME ASC, A.SCHEMA ASC
The CREATEDBY column from SYSSEQUENCES is used as the where clause predicate for the SQ/L report as it matches the customary usage of the CREATOR field which is specified in the SQ/L report request screen. The OWNER of a sequence may indicate the TBCREATOR column from SYSCOLUMNS if the sequence supports an identity column.
The CREATEDBY column will always indicate the Primary authorization ID of the user who created the sequence or identity column and provides a more consistent representation of the object Creator.
