Question

I’m trying to build the next stored proc but it’s not working.

PREPARE STMT FROM 'SELECT a, b, c, d, e FROM TABLE_1 WHERE (`a` like `%?%` OR `b` like `%?%` OR `c` like `%?%` OR `d` like `%?%` OR `e` like `%?%`) LIMIT ?, ?';
EXECUTE STMT USING @search, @skip, @rows;

Basically, I’m trying to search for a string inside one of the columns and return the rows with the columns who fits.
Please help me fix it since I’m getting the next error:

Unknown column '%?%' in 'where clause'

This is because the number of ? should be equal to number of parameters after USING clause. also you have given wrong quotes ? instead of "?" try:

PREPARE STMT FROM 'SELECT a, b, c, d, e FROM TABLE_1 WHERE (`a` like "%?%" OR `b` like "%?%" OR `c` like "%?%" OR `d` like "%?%" OR `e` like "%?%") LIMIT ?, ?';

EXECUTE STMT USING @search, @search, @search, @search, @search, @skip, @rows;

or try

SET @query1 = CONCAT('
    SELECT SQL_CALC_FOUND_ROWS a, b, c, d, e
    FROM TABLE_1
    WHERE (`a` like "%',@search,'%" OR
        `b` like "%',@search,'%" OR
        `c` like "%',@search,'%" OR
        `d` like "%',@search,'%" OR
        `e` like "%',@search,'%")
    LIMIT ',@skip,', ',@rows,'');

    PREPARE stmt FROM @query1; 
    EXECUTE stmt; 
    SELECT FOUND_ROWS() AS total_rows;
    DEALLOCATE PREPARE stmt;
