Fetching rows in DB2

Question

I know in DB2 (using version 9.7) I can select the first 10 rows of a table by using this query:

SELECT * 
FROM myTable
ORDER BY id
FETCH FIRST 10 ROWS ONLY
         


        

Answer 1

You can also use the MYSQL compatibility. You just need to activate the vector compatibility for MYS, and then use Limit and Offset in your queries.

db2set DB2_COMPATIBILITY_VECTOR=MYS
db2stop
db2start
