Stored Procedure Schema

Below code snippets contains the code to find the stored procedure based on the key word. Many times with the tough deliveries and short dead lines it can be possible that, we tend to forget the name of the stored procedure etc... So in that kind of situation this stored procedure will help you where in you can just type in the key word and it will look for that stored procedure. The best part of this procedure is scans all the databases attached on the server and returns you the result set.


if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[Split]') and xtype in (N'FN', N'IF', N'TF'))
 drop function [dbo].[Split]
GO

CREATE FUNCTION dbo.Split
(
 @RowData nvarchar(2000),
 @SplitOn nvarchar(5)
)  
RETURNS @RtnValue table 
(
 Id int identity(1,1),
 Data nvarchar(100)
) 
AS  
BEGIN 
 Declare @Cnt int
 Set @Cnt = 1

 While (Charindex(@SplitOn,@RowData)>0)
 Begin
  Insert Into @RtnValue (data)
  Select 
   Data = ltrim(rtrim(Substring(@RowData,1,Charindex(@SplitOn,@RowData)-1)))

  Set @RowData = Substring(@RowData,Charindex(@SplitOn,@RowData)+1,len(@RowData))
  Set @Cnt = @Cnt + 1
 End
 
 Insert Into @RtnValue (data)
 Select Data = ltrim(rtrim(@RowData))

 Return
END

How to use this procedure.

Here the parameter one 
is the Keyword for scanning. 
Second Parameter used for Searching on 
the specific object FN = Scalar function, IF = In-lined table-function,P
 = Stored procedure,TR = Trigger,V = View
Third paramter is the 
database name, this is the optional parameter, if not given any database
 name it will scan all the database.
