Let's say you have a file named CUSTMAST in library CUSLIB on your iSeries.
This file has multiple data members for each company:
MBR0001 - Company 1 data
MBR0002 - Company 2 data
MBR0003 - Company 3 data
How would you be able to read data from each member since SQL/400 does not allow access to the individual file members?
You would need to:
- Create an ALIAS for each data member so they can be referred to separately.
Example SQL statements:
CREATE ALIAS CUSLIB/MBR0001_ALIAS FOR CUSLIB/CUSTMAST (MBR0001)
CREATE ALIAS CUSLIB/MBR0002_ALIAS FOR CUSLIB/CUSTMAST (MBR0002)
CREATE ALIAS CUSLIB/MBR0003_ALIAS FOR CUSLIB/CUSTMAST (MBR0003)
Now when SQL statements are run against a particular member, use a new ALIAS
Examples of using an ALIAS with the FTSQL statement for selecting records:
FTSQL SQLSTM('SELECT * FROM CUSLIB/MBR0001_ALIAS')
FTSQL SQLSTM('SELECT * FROM CUSLIB/MBR0002_ALIAS')
FTSQL SQLSTM('SELECT * FROM CUSLIB/MBR0003_ALIAS')
