你怎么做一个mysql WHERE something ='something'或者...（PHP）

Question

是否可以像这样做一个OR语句？

WHERE pR.projectRelationId = '$id[ 0 ]' OR '$id[ 1 ]' OR '$id[ 2 ]'
AND pR.type = 'yada' AND

或者您是否必须继续重新进行比较：

        WHERE 
            pR.projectRelationId = '$id[ 0 ]' OR 
            pR.projectRelationId = '$id[ 1 ]' OR 
            pR.projectRelationId = '$id[ 2 ]'
            AND
            pR.type = 'yada' AND

Answer 1

使用IN：

pR.projectRelationId IN ('$id[ 0 ]', '$id[ 1 ]', '$id[ 2 ]')

Answer 2

与IN

一起使用

WHERE pR.projectRelationId IN ('$id[ 0 ]','$id[ 1 ]','$id[ 2 ]') AND pR.type = 'yada' AND
