我是存储过程的新手，我遇到的问题是当我通过PHP调用存储过程时，存储过程返回的结果没有任何值 . 当我直接在MySQL服务器上手动拨打电话时，它工作正常并返回5个值 . 当我通过php调用该过程时，没有值存储在绑定变量中 .
Stored Procedure:
DELIMITER $$
CREATE PROCEDURE `TPE_GET_current_repair` (IN current_repair_vid VARCHAR(45))
BEGIN
SELECT current_repair_vid v1;
SELECT
sys_vendor.vendor,
receive_date,
tape_repair_problem_code.tape_repair_problem_reason,
sys_tape_type.tape_type,
sys_capture_location.capture_location
FROM tape_repair
INNER JOIN `sys_vendor` on tape_repair.vendor_id = sys_vendor.id
INNER JOIN `tape_repair_problem_code` on tape_repair.problem_code = tape_repair_problem_code.id
INNER JOIN `sys_tape_type` on tape_repair.tape_type_id = sys_tape_type.id
INNER JOIN `sys_capture_location` on tape_repair.capture_location_id = sys_capture_location.id
WHERE vid = current_repair_vid;
END
PHP:
$repairData = "CALL TPE_GET_current_repair('$vid')";
if ($stmt = $mysqli->prepare($repairData)) {
$stmt->execute();
$stmt->bind_result($rpr_vendor, $rpr_rcv_date, $rpr_problem, $rpr_tape_type, $rpr_capt_loctn);
$stmt->fetch();
}

我修复了这个问题，我忘记了第一个select语句，它导致语句失败 .
