Question

I have a database table consisting of strings… I need to search for a particular string in the table row by row and return the column number where that string appears… I am using mysql database..

my table is of the form

QID Question Choice1 Choice2 Choice3 Choice4

I am given two strings… first string will be found under Question column and second string will be found in Choice1 or Choice2 or Choice3 or Choice4 … I need to find the column number of the column which has my second string …

Can someone please tell me what to do ?

Answer 1

This is an ugly response but your question is a bit weird.

SELECT COALESCE(IF(col1='thestring',1,NULL), IF(col2='thestring',2,NULL), IF(col3='thestring',3,NULL) ....) FROM somewhere;
