How can it be done - plus sign in query

[Matlak Sandor]

hi

i have the following problem:
i have to SELECT rows from the table with the following WHERE condition: WHERE columna = 3+2.
'3+2' is a string, cannot be modified, comes from a form. but of course MYSQL evaluates the 3+2 expression and tries to select columna=5 (at least i think so :)) and the query makes no results. how can this be solved?

thx
