在TSQL错误消息中获取文件中的行号

考虑下面的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,您可以获得

Line 3
Line 6
Msg 208,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.

报告行2表示相对于批次的行号.批量由GO语句分隔.我们想要得到一个真正的第9行答案.

我也尝试过PowerShell的Invoke-sqlcmd,但更糟糕的是,因为它根本没有检测到这样的错误(Error detection from Powershell Invoke-Sqlcmd not always working?).

有没有一个简单的方法来包装我们的sql脚本与一些帮助来获得所需的真正的错误行？

UPD：我已经更改了错误脚本,以确保它会失败确定…

解决方法

这是我想出的解决方案： https://github.com/mnaoumov/Invoke-SqlcmdEx

现在

> .\Invoke-sqlcmdEx.ps1 -InputFile .\MyScript.sql
Line 3
Line 6
Msg 208,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

以防万一我也在这里列出了脚本.该脚本可能看起来像一个过分的,但它是这样写的,以便完全支持所有sqlCMD脚本功能并正确处理事务

调用-sqlcmdEx.ps1

UPD：@MartinSmith提供了一个整洁的想法,使用LINENO aproach.

这是使用这种方法的版本：https://github.com/mnaoumov/Invoke-SqlcmdEx/blob/LINENO/Invoke-SqlcmdEx.ps1它在每个GO语句之后基本上插入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

它会失败

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

因此,LINENO方法对于在查询批次中必须是第一个的语句将不起作用.以下是此类语句的列表：http://msdn.microsoft.com/en-us/library/ms175502.aspx：CREATE DEFAULT,CREATE FUNCTION,CREATE PROCEDURE,CREATE RULE,CREATE SCHEMA,CREATE TRIGGER和CREATE VIEW.没有提到ALTER语句,但我认为规则也适用于它们
