st: Using wildcards in string variables to drop observations

Dear Statalisters,
I'm a stata-newy and have the following problem: I want to drop all
observations where in a string variable the string "%" appears. I
thought the straightforward command would be ' drop if variable = =
"*%" '. However, using this command, nothing is eliminated. If I
specify the string completly (like ' drop if variable = = "DE12%" '
the observation is eliminated just as I want it. Where is my mistake?
Do wildcards like * not work in these kinds of commands?
Thanks a lot for any piece of help!
Rainer
