是否可以像这样进行 OR 语句？
WHERE pR.projectRelationId = '$id[ 0 ]' OR '$id[ 1 ]' OR '$id[ 2 ]'
AND pR.type = 'yada' AND
还是必须不断重新声明比较:
WHERE
pR.projectRelationId = '$id[ 0 ]' OR
pR.projectRelationId = '$id[ 1 ]' OR
pR.projectRelationId = '$id[ 2 ]'
AND
pR.type = 'yada' AND
最佳答案
使用 IN:
pR.projectRelationId IN ('$id[ 0 ]', '$id[ 1 ]', '$id[ 2 ]')
