How can I use underscores in "LIKE" conditions in Tivoli? [duplicate]

Why does using an Underscore character in a LIKE filter give me all the results? (6 answers)

Closed 6 years ago.

I can't properly use underscores in the LIKE part when I use Tivoli databases.

I connected to a Tivoli database with AQT and just run this query;

select NODE_NAME from NODES where NODE_NAME like '%_SQL'

This query gets as result;

AKHEDEFSRV_SQL
AKHEDEF_SQL
AKLSFS_SQLPAKL1_SQL
AKLSFS_SQLPAKL2_SQL

But also gets

AKLSPRODSQL
AKLSTESTSQL

It looks to me as if Tivoli ignores the underscore in the LIKE part of the query. Anyone has an idea?

Answer 1

The underscore matches a single character, unless it is escaped. Try:

select NODE_NAME from NODES where NODE_NAME like '%__SQL' escape '_'
