违反基数：1241操作数应包含1列PDO

Question

i trying to run this code by pdo

db::query("SELECT v.id, v.rel_x, v.rel_y FROM p_villages v WHERE v.field_maps_id=3
            AND ISNULL(v.player_id) AND (v.rel_x >= ?,?,?,? AND v.rel_x <= ?,?,?,?)
            AND (v.rel_y >= ?,?,?,? AND v.rel_y <= ?,?,?,?)
            AND v.rand_num > 0 ORDER BY v.rand_num LIMIT 1",array(1,2,3,3,1,2,3,3,1,2,3,3,1,2,3,3));

but i found this error

Warning: PDOStatement::execute(): SQLSTATE[21000]: Cardinality violation: 1241 Operand should contain 1 column(s) \

so, i need the output query like SELECT v.id, v.rel_x, v.rel_y FROM p_villages v WHERE v.field_maps_id=3 AND ISNULL(v.player_id) AND (v.rel_x >= 1,2,3,4 AND v.rel_x <= 1,2,3,4) AND (v.rel_y >= 1,2,3,4 AND v.rel_y <= 1,2,3,4) AND v.rand_num > 0 ORDER BY v.rand_num LIMIT 1 and in the parameters i want to pass each parameter of those parameters which here is 16

what should i do ?

Answer 1

this: v.rel_y <= ?,?,?,?

looks weird.

Bound parameters have to be self contained, you cannot build the right or left part of a comparison by more than one.

ie, if you mean to say x >= 5.1 , you cannot put x >= ?.? and pass 2 parameters to the pdo statement. You would then have to pass x >= ? and then bindValue(5.1);
