如何在MYSQL中使用Like语句？

Question

I m facing a problem that my query can execute but when i call the stored procedure meet operand should contain 1 columns. The above is some part of my query

if p_Opt = 'RETRIEVE-P' THEN    

Set @'query' = ('SELECT Company,Branch,user_id,name,priority,email,UserGroup, Status FROM UserAuth WHERE 1=1 ');

    If p_Company Is Not Null  THEN

            Set @'query' = @'query' + ' AND Company LIKE '''+ '%' +  p_Company + '%' + '''';
        END if;

END IF;

What is the problem??Is it correct for my query??

Answer 1

Instead of using single qoutes use double quotes in like query something like below.

 if p_Opt = 'RETRIEVE-P' THEN    

    Set @'query' = ('SELECT Company,Branch,user_id,name,priority,email,UserGroup, Status FROM UserAuth WHERE 1=1 ');

        If p_Company Is Not Null  THEN

                Set @'query' = @'query' + ' AND Company LIKE "%' +  p_Company + '%"';
            END if;
