创建存储过程时，SQL Server中的“=”错误附近的语法不正确

问题描述

我有一个表bankcheques，check和chequedetails现在我创建了

的程序如果bank_id，bankchequeno不存在于bankcheques表insert record.while更新记录我正在检查两个条件，如果chequedetails表中不存在chequeno，则更新bankcheques表中的每个字段。

如果chequedetails表中存在chequeno，则只更新bankcheques表中的status字段。在这里我检查另一个条件。

i我从支票表中根据bankid和chequeend从bankcheques表中获取maxcheueno并比较这两个值然后更新bankcheque表的状态。我在'='附近得到错误的语法错误请帮帮我。谢谢你。



我尝试过的事情：

I have a tables bankcheques,cheques and chequedetails now i create the procedure for
if bank_id,bankchequeno doesn't exist in bankcheques table insert record.while updating the record i am checking two conditions if chequeno not exists in chequedetails table update every field from the bankcheques table.
and if chequeno exists in chequedetails table only update the status field in the bankcheques table. here iam checking another condition.
i am taking maxcheueno from cheques table based on bankid and chequeend from bankcheques table and compare the both values then update status of bankcheque table.I am getting the incorrect syntax near '=' Error Please help me on this.Thanks in Advance.

推荐答案

if(@chqlastno==@lastcheueno)

SQL不使用==作为条件，而是使用=代替。

SQL does not use "==" for conditionals, it uses "=" instead.
