I just totally love the regular expression find/replace tool in SSMS. I thought I would dump out some of my favs that I use here so that, when I need them again, I'll have a single place to refer back to them.

^set \@p(:z+)=.*\n -- finds anything like SET @p1=NULL or SET @P12='hello World' with a carriage return at the end. This is particularly helpful when you are using SQL Profiler to trace calls to stored procedures that have OUTPUT parameters. When you trace SQL Server stored procs with OUT params, SQL Profiler will show you something like this:

Code:

declare @p3 nvarchar(2048)
set @p3=505
declare @p4 nvarchar(256)
set @p4='Whatever'
declare @p5 nvarchar(256)
set @p5='Junk data'
declare @p6 nvarchar(128)
set @p6='Junk data'
exec dbo.GetMyDetailItem @MyId=N'MyId',@ProductId=505,@Description=@p3 output,@DescrKeys=@p4 output,@DescrDescription=@p5 output,@Title=@p6
output
select @p3, @p4, @p5, @p6

This code is not too clean to me and I generally will do at least one Find/Replace (^set \@p(:z+)=.*\n) which yields

Code:

declare @p3 nvarchar(2048)
declare @p4 nvarchar(256)
declare @p5 nvarchar(256)
declare @p6 nvarchar(128)
exec dbo.GetMyDetailItem @MyId=N'MyId',@ProductId=505,@Description=@p3 output,@DescrKeys=@p4 output,@DescrDescription=@p5 output,@Title=@p6
output
select @p3, @p4, @p5, @p6

Much cleaner!

My next find/replace generally is to get rid of all the "extra" DECLARE's and be left with an easier to read doc:

Code:

declare @p3 nvarchar(2048), @p4 nvarchar(256), @p5 nvarchar(256), @p6 nvarchar(128)
exec dbo.GetMyDetailItem @MyId=N'MyId',@ProductId=505,@Description=@p3 output,@DescrKeys=@p4 output,@DescrDescription=@p5 output,@Title=@p6
output
select @p3, @p4, @p5, @p6
