Dear serverCentral
How can I find a particular column in a number of tables.
For example, I have column name , grporder and I want to know which one of the 100 tables it is in...is there a quick way of finding that out?
There is probably something very simple, but I can't see it at the moment

Query the sys.columns view. Join it to sys.tables for the table name, or use the object_name function.

Hi ,

Just an addition to the above method, also I hope you know the database name among the existing the databases in the server, if so you can even use the below script in that database.

SELECT TABLE_NAME,COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME = 'C1'

If you dont know the databasename you have to itrate through each database in the server to check the table which has the your column. In that case you can use the below script.

EXEC master.sys.SP_MSFOREACHDB 'USE ?; IF EXISTS(SELECT 1 FROM INFORMATION_SCHEMA.COLUMNS WHERE COLUMN_NAME = ''C1'') SELECT ''?'' as db_name,table_name as table_name,column_name as column_name from information_schema.columns WHERE COLUMN_NAME = ''C1'''

In the above script just replace C1 with your column name

MC

As a side bar... That's one of the things I miss about SQL Server 2000 and Query Analyzer where you could just press {f4} for such a thing.

--Jeff Moden

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.

Got this somewhere (sorry forgot where) and I use instead of missing "object search" in SQL 2005

Change the "where" clause to limit to object types you want to search

DECLARE @SEARCHSTRING VARCHAR(255), @notcontain Varchar(255)

SELECT @SEARCHSTRING = 'dog', @notcontain = ''

SELECT DISTINCT left(sysobjects.name,60) AS [Object Name] ,

case when sysobjects.xtype = 'P' then 'Stored Proc'

when sysobjects.xtype = 'TF' then 'Function'

when sysobjects.xtype = 'TR' then 'Trigger'

when sysobjects.xtype = 'U' then 'User table'

when sysobjects.xtype = 'V' then 'View'

end as [Object Type]

FROM sysobjects

LEFT JOIN syscomments ON sysobjects.id = syscomments.id

LEFT JOIN syscolumns ON sysobjects.id = syscolumns.id

--WHERE sysobjects.type in ('P','TF','TR','U','V')

WHERE sysobjects.type = 'U'

AND ((CHARINDEX(@SEARCHSTRING,syscomments.text)>0

AND ((CHARINDEX(@notcontain,syscomments.text)=0

or CHARINDEX(@notcontain,syscomments.text)<>0)) )

OR

CHARINDEX(@SEARCHSTRING,syscolumns.name)>0

)

ORDER BY [Object Type], [Object Name]

here's another script that i use a lot;

i stick it in master, and then in any database i might type "sp_find order" in any database;

and it returns all tables(or views) that contain the string first, and then all the column names along with their table/view name that contain the string in the column name;

CREATE procedure [dbo].[sp_find]

@findcolumn varchar(50)

AS

BEGIN

SET NOCOUNT ON

SELECT

TableFound,

ColumnFound

FROM

(

SELECT

1 AS SortOrder,

sysobjects.name AS TableFound,

'' AS ColumnFound

FROM sysobjects

WHERE sysobjects.xtype IN('U' ,'V')

AND sysobjects.name LIKE '%' + @findcolumn + '%'

UNION ALL

SELECT

2 AS SortOrder,

sysobjects.name AS TableFound,

syscolumns.name AS ColumnFound

FROM sysobjects

INNER JOIN syscolumns ON sysobjects.id=syscolumns.id

WHERE sysobjects.xtype IN('U' ,'V')

AND syscolumns.name like '%' + @findcolumn + '%'

) X

ORDER BY

SortOrder,

TableFound,

ColumnFound

END
