CodeIgniter：多行查询

Question

我有一个非常好的查询，当我在我的数据库中使用它而不是在CodeIgniter中时它会起作用。查询看起来像这样

SET @student_id = 1;

INSERT IGNORE INTO tbl_beschikbare_data (datum_tijd) VALUES ('22/22/2222');
SET @bd_id = LAST_INSERT_ID();

INSERT INTO tbl_student_beschikbare_data (student_id,bd_id) VALUES(@student_id, @bd_id);

这就是我在CodeIgniter中所拥有的：

public function save($t){

$this->db->query("SET @student_id = 1;INSERT IGNORE INTO tbl_beschikbare_data (datum_tijd) VALUES ('".$t."');SET @bd_id = LAST_INSERT_ID();INSERT INTO tbl_student_beschikbare_data (student_id,bd_id) VALUES(@student_id, @bd_id);
"); }

Answer 1

好好想通了..效果很好

public function save($datum_tijd) {

 $this->db->query("SET @student_id = 1;"); 

$this->db->query("INSERT IGNORE INTO tbl_beschikbare_data (datum_tijd) VALUES ('".$datum_tijd."');"); 

$this->db->query("SET @bd_id = LAST_INSERT_ID();"); 
$this->db->query("INSERT INTO tbl_student_beschikbare_data (student_id,bd_id) VALUES(@student_id, @bd_id);");

 }
