Like string in embedded SQL

I need to look for a string like 'Access plan not updated' in an embedded
SQL statement in an RPG program.

If I do the following in STRSQL it works.

SELECT count(*) FROM out132 WHERE OUT132
Like('%Access plan not updated%')

but the following in embedded SQL does not work.

Exec Sql Select Count(*)
Into :Count
From QTEMP/OUT132
Where OUT132 Like('%:InSearchString%');

When I look at the complied there is no data field being moved in so
obviously it is not seeing the ':' in the string.

Any ideas how to code this so it sees the search string?

I know that one solution would be to use dynamic SQL but would like to
ignore that options if I could.
