Msg 245，Level 16，State 1，Procedure proc_LoansProcessed_ToDate，Line 178 [批处理开始第7行]转换varchar时转换失败价值＆＃39;）＆＃39;数据类型int。

Answer 1

我认为在连接[Loan_ID] +＆＃39;）时遇到错误。在

([BorrowerName]+' '+'('+[Loan_ID]+')') Name2

使用concat函数

Answer 2

将with open("somefile.py", encoding="utf-8") as f: exec(f.read())投射到loan_Id

varchar

到

( [borrowername] + ' ' + '(' + [loan_id] + ')' ) Name2

将[borrowername] + ' ' + '(' + [cast(loan_id as varchar(50))] + ')' as Name2与任何int连接时，sql引擎会隐式将字符串转换为int，因为string的优先级高于int。因此，您需要明确地将varchar转换为loan_id以避免此问题

此外，我刚删除了不需要的括号，使代码看起来更清晰

Answer 3

将查询的最后一行更改为 -

( [borrowername] + ' ' + '(' + CONVERT(NVARCHAR(10),[loan_id]) + ')' )Name2

注意 - 根据您的要求，在上面的行中替换NVARCHAR（10）。

我运行此查询时一直收到错误。有谁看到我搞砸了？
