SQL query of multi-member file on AS400

Question

On AS400 in interactive SQL in a 5250 session,

select * from myfile

returns rows from one member only when myfile has more than one member.

Answer 1

SQL Alias

OS/400 R430 and later support an SQL alias statement. Create an alias for each member that must be accessed, then reference the alias from the application. The alias is a persistent object -- it must be created only once. The member referenced in the CREATE ALIAS does not have to exist when the ALIAS is created. Any SQL tool, such as OS/400 or i5/OS interactive SQL (STRSQL) or iSeries Navigator's Run SQL Scripts, can be used to create the alias, for example:

CREATE ALIAS MYLIB.FILE1MBR1 FOR MYLIB.MYFILE(MBR1) 
CREATE ALIAS MYLIB.FILE1MBR2 FOR MYLIB.MYFILE(MBR2)
