How to find a text inside SQL Server procedures / triggers?

Question

I have a linkedserver that will change. Some procedures call the linked server like this: [10.10.100.50].dbo.SPROCEDURE_EXAMPLE. We have triggers also doing this kind of work. We need to find all places that uses [10.10.100.50] to change it.

In SQL Server Management Studio Express, I didn't find a feature like "find in whole database" in Visual Studio. Can a special sys-select help me find what I need?

Answer 1

here is a portion of a procedure I use on my system to find text....

DECLARE @Search varchar(255)
SET @Search='[10.10.100.50]'

SELECT DISTINCT
    o.name AS Object_Name,o.type_desc
    FROM sys.sql_modules        m 
        INNER JOIN sys.objects  o ON m.object_id=o.object_id
    WHERE m.definition Like '%'+@Search+'%'
    ORDER BY 2,1

Answer 2

You can find it like

SELECT DISTINCT OBJECT_NAME(id) FROM syscomments WHERE [text] LIKE '%User%'

It will list distinct stored procedure names that contain text like 'User' inside stored procedure. More info

Answer 3

[Late answer but hopefully usefull]

Using system tables doesn't always give 100% correct results because there might be a possibility that some stored procedures and/or views are encrypted in which case you'll need to use DAC connection to get the data you need.

I'd recommend using a third party tool such as ApexSQL Search that can deal with encrypted objects easily.

Syscomments system table will give null value for text column in case object is encrypted.

Answer 4

-- Declare the text we want to search for
DECLARE @Text nvarchar(4000);
SET @Text = 'employee';

-- Get the schema name, table name, and table type for:

-- Table names
SELECT
       TABLE_SCHEMA  AS 'Object Schema'
      ,TABLE_NAME    AS 'Object Name'
      ,TABLE_TYPE    AS 'Object Type'
      ,'Table Name'  AS 'TEXT Location'
FROM  INFORMATION_SCHEMA.TABLES
WHERE TABLE_NAME LIKE '%'+@Text+'%'
UNION
 --Column names
SELECT
      TABLE_SCHEMA   AS 'Object Schema'
      ,COLUMN_NAME   AS 'Object Name'
      ,'COLUMN'      AS 'Object Type'
      ,'Column Name' AS 'TEXT Location'
FROM  INFORMATION_SCHEMA.COLUMNS
WHERE COLUMN_NAME LIKE '%'+@Text+'%'
UNION
-- Function or procedure bodies
SELECT
      SPECIFIC_SCHEMA     AS 'Object Schema'
      ,ROUTINE_NAME       AS 'Object Name'
      ,ROUTINE_TYPE       AS 'Object Type'
      ,ROUTINE_DEFINITION AS 'TEXT Location'
FROM  INFORMATION_SCHEMA.ROUTINES 
WHERE ROUTINE_DEFINITION LIKE '%'+@Text+'%'
      AND (ROUTINE_TYPE = 'function' OR ROUTINE_TYPE = 'procedure');

Answer 5

This will work for you:

use [ANALYTICS]  ---> put your DB name here
GO
SELECT sm.object_id, OBJECT_NAME(sm.object_id) AS object_name, o.type, o.type_desc, sm.definition
FROM sys.sql_modules AS sm
JOIN sys.objects AS o ON sm.object_id = o.object_id
where sm.definition like '%SEARCH_WORD_HERE%' collate SQL_Latin1_General_CP1_CI_AS
ORDER BY o.type;
GO

Answer 6

There are much better solutions than modifying the text of your stored procedures, functions, and views each time the linked server changes. Here are some options:

1. Update the linked server. Instead of using a linked server named with its IP address, create a new linked server with the name of the resource such as Finance or DataLinkProd or some such. Then when you need to change which server is reached, update the linked server to point to the new server (or drop it and recreate it).

2. While unfortunately you cannot create synonyms for linked servers or schemas, you CAN make synonyms for objects that are located on linked servers. For example, your procedure [10.10.100.50].dbo.SPROCEDURE_EXAMPLE could by aliased. Perhaps create a schema datalinkprod, then CREATE SYNONYM datalinkprod.dbo_SPROCEDURE_EXAMPLE FOR [10.10.100.50].dbo.SPROCEDURE_EXAMPLE;. Then, write a stored procedure that accepts a linked server name, which queries all the potential objects from the remote database and (re)creates synonyms for them. All your SPs and functions get rewritten just once to use the synonym names starting with datalinkprod, and ever after that, to change from one linked server to another you just do EXEC dbo.SwitchLinkedServer '[10.10.100.51]'; and in a fraction of a second you're using a different linked server.

There may be even more options. I highly recommend using the superior techniques of pre-processing, configuration, or indirection rather than changing human-written scripts. Automatically updating machine-created scripts is fine, this is preprocessing. Doing things manually is awful.

select text
from syscomments
where text like '%your text here%'

Answer 8

This one i tried in SQL2008, which can search from all the db at one go.

Create table #temp1 
(ServerName varchar(64), dbname varchar(64)
,spName varchar(128),ObjectType varchar(32), SearchString varchar(64))

Declare @dbid smallint, @dbname varchar(64), @longstr varchar(5000)
Declare @searhString VARCHAR(250)

set  @searhString='firstweek'

declare db_cursor cursor for 
select dbid, [name] 
from master..sysdatabases
where [name] not in ('master', 'model', 'msdb', 'tempdb', 'northwind', 'pubs')



open db_cursor
fetch next from db_cursor into @dbid, @dbname

while (@@fetch_status = 0)
begin
    PRINT 'DB='+@dbname
    set @longstr = 'Use ' + @dbname + char(13) +        
        'insert into #temp1 ' + char(13) +  
        'SELECT @@ServerName,  ''' + @dbname + ''', Name 
        , case  when [Type]= ''P'' Then ''Procedure''
                when[Type]= ''V'' Then ''View''
                when [Type]=  ''TF'' Then ''Table-Valued Function'' 
                when [Type]=  ''FN'' Then ''Function'' 
                when [Type]=  ''TR'' Then ''Trigger'' 
                else [Type]/*''Others''*/
                end 
        , '''+ @searhString +''' FROM  [SYS].[SYSCOMMEnTS]
        JOIN  [SYS].objects ON ID = object_id
        WHERE TEXT LIKE ''%' + @searhString + '%'''

 exec (@longstr)
 fetch next from db_cursor into @dbid, @dbname
end

close db_cursor
deallocate db_cursor
select * from #temp1
Drop table #temp1

Answer 9

You can search within the definitions of all database objects using the following SQL:

SELECT 
    o.name, 
    o.id, 
    c.text,
    o.type
FROM 
    sysobjects o 
RIGHT JOIN syscomments c 
    ON o.id = c.id 
WHERE 
    c.text like '%text_to_find%'

Answer 10

Any searching with select statement yield you only object name, where search keyword contains. Easiest and efficient way is get script of procedure/function and then search in generated text file, I also follows this technique :) So you are exact pinpoint.

Answer 11

SELECT ROUTINE_TYPE, ROUTINE_NAME, ROUTINE_DEFINITION
FROM INFORMATION_SCHEMA.ROUTINES 
WHERE ROUTINE_DEFINITION LIKE '%Your Text%' 

Answer 12

Just wrote this for generic full outer cross ref

create table #XRefDBs(xtype varchar(2),SourceDB varchar(100), Object varchar(100), RefDB varchar(100))

declare @sourcedbname varchar(100),
        @searchfordbname varchar(100),
        @sql nvarchar(4000)
declare curs cursor for
    select name 
    from sysdatabases
    where dbid>4
open curs
fetch next from curs into @sourcedbname
while @@fetch_status=0
    begin
    print @sourcedbname
    declare curs2 cursor for 
        select name 
        from sysdatabases
        where dbid>4
        and name <> @sourcedbname
    open curs2
    fetch next from curs2 into @searchfordbname
    while @@fetch_status=0
        begin
        print @searchfordbname
        set @sql = 
        'INSERT INTO #XRefDBs (xtype,SourceDB,Object, RefDB)
        select DISTINCT o.xtype,'''+@sourcedbname+''', o.name,'''+@searchfordbname+'''
        from '+@sourcedbname+'.dbo.syscomments c
        join '+@sourcedbname+'.dbo.sysobjects o on c.id=o.id
        where o.xtype in (''V'',''P'',''FN'',''TR'')
        and (text like ''%'+@searchfordbname+'.%''
          or text like ''%'+@searchfordbname+'].%'')'
        print @sql
        exec sp_executesql @sql
        fetch next from curs2 into @searchfordbname
        end
    close curs2
    deallocate curs2
    fetch next from curs into @sourcedbname
    end
close curs
deallocate curs

select * from #XRefDBs

Answer 13

I use this one for work. leave off the []'s though in the @TEXT field, seems to want to return everything...

SET NOCOUNT ON

DECLARE @TEXT   VARCHAR(250)
DECLARE @SQL    VARCHAR(250)

SELECT  @TEXT='10.10.100.50'

CREATE TABLE #results (db VARCHAR(64), objectname VARCHAR(100),xtype VARCHAR(10), definition TEXT)

SELECT @TEXT as 'Search String'
DECLARE #databases CURSOR FOR SELECT NAME FROM master..sysdatabases where dbid>4
    DECLARE @c_dbname varchar(64)   
    OPEN #databases
    FETCH #databases INTO @c_dbname   
    WHILE @@FETCH_STATUS  -1
    BEGIN
        SELECT @SQL = 'INSERT INTO #results '
        SELECT @SQL = @SQL + 'SELECT ''' + @c_dbname + ''' AS db, o.name,o.xtype,m.definition '   
        SELECT @SQL = @SQL + ' FROM '+@c_dbname+'.sys.sql_modules m '   
        SELECT @SQL = @SQL + ' INNER JOIN '+@c_dbname+'..sysobjects o ON m.object_id=o.id'   
        SELECT @SQL = @SQL + ' WHERE [definition] LIKE ''%'+@TEXT+'%'''   
        EXEC(@SQL)
        FETCH #databases INTO @c_dbname
    END
    CLOSE #databases
DEALLOCATE #databases

SELECT * FROM #results order by db, xtype, objectname
DROP TABLE #results

Answer 14

I've used these in the past:

• Searching all user stored procedures for a table name
• Search and replace SQL Server data in all columns of all tables

In this particular case, where you need to replace a specific string across stored procedures, the first link is probably more relevant.

A little off-topic, the Quick Find add-in is also useful for searching object names with SQL Server Management Studio. There's a modified version available with some improvements, and another newer version also available on Codeplex with some other useful add-ins as well.
