Question

是否可以在多个LIKE查询中找出匹配的列？

e.g：

SELECT * FROM table WHERE col_a LIKE = '%B' OR col_b LIKE = '%A'

if(MATCHED COL_A){
   do this;
}else{
   do that;
}

Answer 1

SELECT col_a, col_b FROM table WHERE col_a LIKE "%B" OR col_b LIKE "%A"

if (strpos($colA, $needle) !== false) {
// do this
} elseif (strpos($colB, $needle) !== false) {
// do that
}

Answer 2

你可以简单地把你的条件放在select语句中，并用新的别名命名，对于匹配的列，它的布尔值为0/1，而=之后也没有任何意义

SELECT *,
col_a LIKE  '%B' AS match_cola,
col_b LIKE  '%A' AS match_colb
FROM table WHERE col_a LIKE '%B' OR col_b LIKE '%A'

从查询中获取结果，您可以将其检查为

$result = fetch result from query;
//loop
if($result['match_cola'] == 1){
echo 'col_a matched';
}
//end loop

检查MySQL上哪个列匹配查询
