MYSQL在我的查詢中忽略AND子句

Question

我有以下查詢，AND狀態= 1被忽略，我得到所有的狀態，而不是隻有等於1.我的錯誤在哪裏？

$query = " 
       SELECT state, id, variable, name, {$columns->specific}, {$columns->allExcept}, {$columns->specificExclude}, {$columns->relationAllExcept}, repeatable 

       FROM #__epc_fieldsgroups 
       WHERE FIND_IN_SET({$relationRecordId}, {$columns->specific}) 

       OR {$columns->allExcept} != 0 
       AND FIND_IN_SET({$relationRecordId}, {$columns->allExcept}) = 0 

       AND state = 1 
       ORDER BY ordering 
      "; 

Answer 1

你需要定義的開始和結束，並使用括號

$query = " 
       SELECT state, id, variable, name, {$columns->specific}, {$columns->allExcept}, {$columns->specificExclude}, {$columns->relationAllExcept}, repeatable 

       FROM #__epc_fieldsgroups 
       WHERE FIND_IN_SET({$relationRecordId}, {$columns->specific}) 

       OR {$columns->allExcept} != 0 
       AND {FIND_IN_SET({$relationRecordId}, {$columns->allExcept}) = 0} 

       AND {state = 1} 
       ORDER BY ordering 
      ";
