Hello,

I search to remove two string like this in a script file
IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[MSmerge_del*]'))
DROP TRIGGER [dbo].[MSmerge*]

Open in new window

I try the following without good result
$DIRECTORY="c:\temp"
$script=$DIRECTORY + "\" + ".Drop.Triggers.sql"
$Sql = [IO.File]::ReadAllText($script)
$Sql -replace '(?s)drop trigger \[MSmerge_.*?\r\nGO' -replace '(?s) \[MSmerge_.*?\r' , '' | Out-File $script

Open in new window


Why?

Thanks

Guess this is a continuation from https://www.experts-exchange.com/questions/28960354/script-smo-triggers.html ?
You want to remove the complete line, I assume. What about the create statement certainly following the drop?

Yes, I always try without result
$DIRECTORY="c:\temp"
$script=$DIRECTORY + "\" + ".Drop.Triggers.sql"
$Sql = [IO.File]::ReadAllText($script)
$Sql -replace '(?s)drop trigger \[MSmerge_.*?\r\nGO' -replace '(?s) \[MSmerge_.*?\r' , '' | Out-File $script

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

I didn't get your last response. You didn't answer to my questions at all. I think you want to remove all lines written out below:
IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[MSmerge_del*]'))
DROP TRIGGER [dbo].[MSmerge*]
GO
CREATE TRIGGER [dbo].[MSmerge*] /* and further text here */
/* ... */
GO

Open in new window

where the "*" means text parts to ignore when searching. Correct?

Following, T-SQL code :
IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[MSmerge_del_2DF5CAAAAF3D4CB0B6497DE4645ABC11]'))
DROP TRIGGER [dbo].[MSmerge_del_2DF5CAAAAF3D4CB0B6497DE4645ABC11]
GO
IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[MSmerge_ins_2DF5CAAAAF3D4CB0B6497DE4645ABC11]'))
DROP TRIGGER [dbo].[MSmerge_ins_2DF5CAAAAF3D4CB0B6497DE4645ABC11]
GO
IF  EXISTS (SELECT * FROM sys.triggers WHERE object_id = OBJECT_ID(N'[dbo].[MSmerge_upd_2DF5CAAAAF3D4CB0B6497DE4645ABC11]'))
DROP TRIGGER [dbo].[MSmerge_upd_2DF5CAAAAF3D4CB0B6497DE4645ABC11]

Open in new window

This works for me:
$DIRECTORY="c:\temp"
$script=$DIRECTORY + "\" + ".Drop.Triggers.sql"
(Get-Content $script) -replace '.+MSMerge_.*', '' -join "`r`n" -replace '\r\n\r\n\r\nGO', '' | Out-File $script

Open in new window

but you might have to add or remove a \r\n combination from the pattern.
