Question

每次我尝试调用我的存储过程时，都会收到以下错误：

Msg 245，Level 16，State 1，Procedure P_KB_GET_GK_UEBERSICHT，第16行

将varchar值'diverse'转换为数据类型int时转换失败。

某些示例值（或示例调用）如下所示：

exec P_KB_GET_GK_UEBERSICHT '','','','','D2335548','','Lindner',''

我根本不明白这个错误信息。他在diverse中提到了什么。此外，转换为INT会出现什么问题？第二个和最后一个参数是INT，但即使没有单引号，错误消息也保持不变。

为了给你提供所有信息，我将添加存储过程。

我正在使用SQL-Server 2008。

更新：它也不适用于数值：

exec P_KB_GET_GK_UEBERSICHT 0,0,0,'','D2335548','','Lindner',0

您对存储过程的调用是错误的。对于前三个参数，SQL Server分别需要tinyint，int和bigint，但是你传递''被解释为varchar。看看你的proc，如果你想要默认值，我认为你需要将所有三个传递为0。

编辑

你的SQL错了。取代

if @gueltjahr = '0'

使用

if @gueltjahr = 0

转换[T-SQL / SQL Server]时转换失败
