Ways to Search for a Pattern in all Stored Procedures and then Open it to be Altered

How can you search all the Stored Procedures for a Pattern and then open the stored procedures to be edited?

Is there anything built inside of SQL Server 2005?

Or are there any 3rd party addins that will do this searching?

I am also using Red Gate's SQL Prompt but I have not noticed that option.

Currently I am using the following command to do the searching

SELECT ROUTINE_SCHEMA, ROUTINE_NAME, ROUTINE_DEFINITION 
    FROM INFORMATION_SCHEMA.ROUTINES 
    WHERE ROUTINE_DEFINITION LIKE '%tblVacationAllocationItem%' 
    AND ROUTINE_TYPE='PROCEDURE'
    ORDER BY ROUTINE_SCHEMA, ROUTINE_NAME

This works pretty good but it returns the content of the stored procedure in one of the columns, which is hard to read. So I have to use the Object Explorer to find and open the stored procedure to see the full content.

Edited: SQL Dependency Tracker allows you to dynamically explore all your database object dependencies, using a range of graphical layouts. This looks like it would answer a few of the questions when searching for a pattern. Any other software similar to SQL Dependency Tracker?

From stackoverflow

  • Unfortunately, there is no feature in SQL Server 2005 other than querying, to find stored procedures based on their contents. The only thing you can do is filter by name in the object explorer.

    I use Visual Studio Database Edition to accomplish this task.

  • There is a open source stored procedure called sp_grep that allows for you to find database objects based on the DDL/code of their makup. I use this procedure all the time to find objects that meet certain criteria. This is very useful in Database refactoring.

    To programmatically open and modify SQL objects you can use the SQLDMO object in any .Net application. Here is some examples of using SQLDMO.

    Example: exec sp_grep 'colA='

    SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER OFF
GO

* Stored procedure  sp_grep 
* SQL Server:   Microsoft SQL Server 6.0, 4.21 for Windows NT, 
*               Microsoft SQL Server 4.2 for OS/2.
* Author:       Andrew Zanevsky, AZ Databases, Inc.
* Version/Date: Version 1.1,  October 26, 1995
* Description:  Searches syscomments table in the current database
*               for occurences of a combination of strings. 
*               Correclty handles cases when a substring begins in 
*               one row of syscomments and continues in the next. 
* Parameters: - @parameter describes the search:
*               string1 {operation1 string2} {operation2 string 3} ...
*               where - stringN is a string of characters enclosed in
*                       curly brackets not longer than 80 characters. 
*                       Brackets may be omitted if stringN does not 
*                       contain spaces or characters: +,-,&;
*                     - operationN is one of the characters: +,-,&.
*               Parameter is interpreted as follows:
*               1.Compose the list of all objects where string1 occurs.
*               2.If there is no more operations in the parameter,
*                 then display the list and stop. Otherwise continue.
*               3.If the next operation is + then add to the list all 
*                   objects where the next string occurs;
*                 else if the next operation is - then delete from the 
*                   list all objects where the next string occurs;
*                 else if the next operation is & then delete from the 
*                   list all objects where the next string does not 
*                   occur (leave in the list only those objects where 
*                   the next string occurs);
*               4.Goto step 2.
*               Parameter may be up to 255 characters long, and may not 
*               contain <CarriageReturn> or <LineFeed> characters.
*               Please note that operations are applied in the order
*               they are used in the parameter string (left to right). 
*               There is no other priority of executing them. Every 
*               operation is applied to the list combined as a result 
*               of all previous operations.
*               Number of spaces between words of a string matters in a
*               search (e.g. "select *" is not equal to "select  *").
*               Short or frequently used strings (such as "select") may 
*               produce a long result set.
*
*             - @case: i = insensitive / s = sensitive (default)
*               Insensitive search is performed regardless of this parameter 
*               if SQL Server is set up with case insensitive sort order.
*
* Examples:     sp_grep employee 
*                 list all objects where string 'employee' occurs;
*               sp_grep employee, i
*                 list all objects where string 'employee' occurs in 
*                 any case (upper, lower, or mixed), such as 
*                 'EMPLOYEE', 'Employee', 'employee', etc.;
*               sp_grep 'employee&salary+department-trigger'
*                 list all objects where either both strings 'employee'
*                 and 'salary' occur or string 'department' occurs, and 
*                 string 'trigger' does not occur;
*               sp_grep '{select FirstName + LastName}'
*                 list all objects where string 
*                 "select FirstName + LastName" occurs;
*               sp_grep '{create table}-{drop table}'
*                 list all objects where tables are created and not 
*                 dropped.
*

    Rune Grimstad : And it works! :-) Great stuff

  • To query the definition of an object, one could use syscomments. For example:

    select * from syscomments where text like '%tblVacationAllocationItem%'

    While this will work for most scenarios, if the definition is longer than 4000 characters, there will exist multiple syscomment rows for a single object. Although unlikely, it is possible that your search phrase spans multiple syscomment rows.

  • Not the answer to your question, but we save all our SProcs as separate files - easier to globally make changes using a Programmer's Editor, and they are easy to get into version management repository (SVN in our case)

  • I have posted the code in the following article for a Stored Proc that works in SQL 2000 and above that does a comprehensive search (across Procs, Functions, Views, Defaults, Jobs, etc.) and can optionally ignore comments and optionally ignore string literals. You can find it at SQLServerCentral.com :

    http://www.sqlservercentral.com/articles/Stored+Procedure/62975/

    It does not automatically open anything for editing but does give the line number of where it matches the text and takes into account the 4000-character chunks as mentioned by Cadaeic. I was planning on updating the article soon to include a loop across all databases and even to include some of my SQL# RegEx functions (for Object Name matching as well as the search string).

    Gerhard Weiss : Thanks Solomon. I actually use SQL#. (Very nice product!) Any enhancements with using RegEx would be most appretiated.
    Gerhard Weiss : I am getting a 'String or binary data would be truncated.' I did modify .sql to be run inline instead of a stored procedure so I am going to look into it to see if my changes effected this. I am using SQL Server 2005.
