带WHERE子句的MySQL语法错误

Question

could you check and tell me where i have made a mistake? Here is the code:

$sql = "SELECT prekės.* , CONCAT(vartotojai.name) as v_name
        FROM prekės 
            LEFT JOIN vartotojai
            ON vartotojai.V_ID=prekės.V_ID
        ORDER BY prekės.date
        LIMIT $offset, $rec_limit
        WHERE prekės.category='Telefonai'";

The error comes from the last line with WHERE clause.

Answer 1

Clause order is incorrect : WHERE -> ORDER -> LIMIT :

$sql = "SELECT prekės.*
             , CONCAT(vartotojai.name) as v_name
        FROM prekės LEFT JOIN vartotojai ON vartotojai.V_ID=prekės.V_ID
        WHERE prekės.category='Telefonai'
        ORDER BY prekės.date
        LIMIT $offset, $rec_limit
       ";

Answer 2

Check the order . ORDER and LIMIT should go after WHERE .
