Question

考虑以下sql脚本

:ON ERROR EXIT

PRINT 'Line 3'
GO

PRINT 'Line 6'
GO

SELECT * FROM NonExistingTable
GO

PRINT 'Line 12'
GO

使用SQLCMD

运行时

> sqlcmd -i MyScript.sql
Line 3
Line 6
Msg 208, Level 16, State 1, Server MyServer, Line 2
Invalid object name 'NonExistingTable'.

当您在启用了SQLCMD模式的SQL Server Management Studio中运行时，您将获得

Line 3
Line 6
Msg 208, Level 16, State 1, Server MyServer, Line 2
Invalid object name 'NonExistingTable'.
** An error was encountered during execution of batch. Exiting.

但是，当您双击错误行时，查询编辑器将跳转到有问题的行。

报告第2行表示相对于批次的行号。批处理由GO语句分隔。我们希望获得真正的第9行答案。

我还尝试过PowerShell的 Invoke-Sqlcmd ，但情况更糟，因为它根本没有检测到这样的错误（Error detection from Powershell Invoke-Sqlcmd not always working?）。

是否有一种简单的方法可以使用一些助手来包装我们的sql脚本以获得所需的真实错误行？

UPD ：我已经更改了错误脚本以确保它确实会失败...

以下是我提出的解决方案：https://github.com/mnaoumov/Invoke-SqlcmdEx

现在

> .\Invoke-SqlcmdEx.ps1 -InputFile .\MyScript.sql
Line 3
Line 6
Msg 208, Level 16, State 1, Server MyServer, Script .\MyScript.ps1, Line 9
Invalid object name 'NonExistingTable'.

sqlcmd failed for script .\MyScript.ps1 with exit code 1
At C:\Dev\Invoke-SqlcmdEx\Invoke-SqlcmdEx.ps1:77 char:18
+             throw <<<<  "sqlcmd failed for script $InputFile with exit code $LASTEXITCODE"
    + CategoryInfo          : OperationStopped: (sqlcmd failed f...ith exit code 1:String) [], RuntimeException
    + FullyQualifiedErrorId : sqlcmd failed for script .\MyScript.ps1 with exit code 1

它有一个正确的第9行输出

以防我在这里插入脚本。该脚本可能看起来像一个矫枉过正，但它是这样编写的，以便完全支持所有SQLCMD脚本功能并正确处理事务

UPD ：@MartinSmith提供了一个使用 LINENO aproach的好主意。

以下是使用此方法的版本：https://github.com/mnaoumov/Invoke-SqlcmdEx/blob/LINENO/Invoke-SqlcmdEx.ps1它基本上在每个 GO 语句后插入 LINENO [对应行号] 。

但是如果我们考虑以下脚本

IF NOT EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID('dbo.MyFunction') AND type = 'FN')
    EXEC sp_executesql N'CREATE FUNCTION dbo.MyFunction() RETURNS int AS BEGIN RETURN 0 END'
GO
LINENO 3

ALTER FUNCTION dbo.MyFunction()
RETURNS int
AS
BEGIN
    RETURN 42
END
GO

会失败

> sqlcmd -i MyScript.sql
Msg 111, Level 15, State 1, Server MyServer, Line 5
'ALTER FUNCTION' must be the first statement in a query batch.
Msg 178, Level 15, State 1, Server MyServer, Line 9
A RETURN statement with a return value cannot be used in this context.

因此 LINENO 方法不适用于必须是查询批处理中的第一个语句。以下是此类语句的列表：http://msdn.microsoft.com/en-us/library/ms175502.aspx：创建默认值，创建函数，创建过程，创建规则，创建模式，创建触发器和创建视图。没有提到ALTER语句，但我认为该规则也适用于它们
