Is there a way to make SQL respect the DDS ALTSEQ keyword?
For example, given a table 'TESTFILE' with the following DDS definition:
A R RECORD
A FIELD 4A
A K FIELD
If I put 3 records into the file, with the values for 'FIELD' of '0001' '0002' and '000A', the collating sequence specified should index the records in the following order:
0001 0002 000A
In RPG a *HIVAL SETGT followed by a READP correctly returns 000A as being the last record.
However when attempting access the table with SQL, the ALTSEQ keyword isn't being respected.
SELECT MAX(FIELD) FROM TESTFILE
MAX ( FIELD ) 0002
SELECT FIELD FROM TESTFILE ORDER BY FIELD
FIELD 000A 0001 0002
Looking at the DB2 manuals it seems that DB2 looks for a collating sequence specified at database level - not at file level and so is not respecting my ALTSEQ keyword - can I force it to?
Thanks in advance, Stu
