mysql - Does an additional "AND `columnname` LIKE '%'" hurt performance? -



simple question: adding query hurt performance in mysql or optimized away?

and `name` '%' 

i've got no big database here test on.

by way, want because want users able send parameters server-side script grabs prepared statement specified user , inserts parameters. want users able omit parameters when searching without hurting performance, , like relatively slow, right?

like's can expensive indeed, depending on indexes have on name field. have tried measure query?

explain [extended] select [...] , `name` '%' 

see http://dev.mysql.com/doc/refman/5.0/en/explain.html

then mysql give indications whether has optimised unnecessary clause away or not.
