我有两个存储过程，我需要将记录（比如选择每个下一个n记录）分页到第一个选择所有匹配记录的记录。

CREATE PROCEDURE `trans_all`(IN varphone VARCHAR(15))
BEGIN
  Select
  loans.amt,
  loans.date,
  loans.pay_period,
  borrower.phone As borrower_phone,
  borrower.name As borrower_name,
  lender.phone As lender_phone,
  lender.name As lender_name,
From
  loans Left Join
  users borrower On borrower.id = loans.borrower_id Left Join
  users lender On lender.id = loans.lender_id
Where
   (lender.phone = varphone) or (borrower.phone = varphone);
END

然后我得到 php 的计数；像这样

$result = $mysqli->query(sprintf("call trans_all('%s')",$phone));
$num_recs = $result->num_rows;

然后我需要选择精确的记录来执行此操作

$result = $mysqli->query(sprintf("call trans_history('%s','%s','%s')",$phone,$start,$limit));

$row = $result->fetch_assoc(); // this like gives the error Commands out of sync; you can't run this command now

第二个存储过程是

CREATE PROCEDURE `trans_history`(IN varphone VARCHAR(15), IN page INT, IN items INT)
BEGIN
  Select
  loans.amt,
  loans.date,
  loans.pay_period,
  borrower.phone As borrower_phone,
  borrower.name As borrower_name,
  lender.phone As lender_phone,
  lender.name As lender_name,
From
  loans Left Join
  users borrower On borrower.id = loans.borrower_id Left Join
  users lender On lender.id = loans.lender_id
Where
   (lender.phone = varphone) or (borrower.phone = varphone)  LIMIT page , items;
END

什么可能导致此错误？

SP 返回包含状态的第二个结果集。您需要next_result()在进行后续查询之前使用。

$result = $mysqli->query(sprintf("call trans_all('%s')",$phone));
$num_recs = $result->num_rows; 
$result->close();
$mysqli->next_result(); // <- you need this before you make another query

//Then make call second SP
$result = $mysqli->query(sprintf("call trans_history('%s','%s','%s')",$phone,$start,$limit));
$row = $result->fetch_assoc();
$result->close();
$mysqli->next_result();
