I cannot find a way to join objects using the database_id.
I am trying to write an audit query which scans through the tables by accepting the database name as parameter.
I want to avoid dynamic queries.
Is it possible?
like
SELECT *
FROM information_schema.tables a
JOIN sys.tables b
ON a.datbase_id = b.database_id
AND b.database_name = 'testdb'
Give this a go.
select *
from
INFORMATION_SCHEMA.TABLES it
inner join sys.tables st
on st.name = it.table_name
where it.TABLE_CATALOG = 'testdb'
First of all, there is no such column as database_id in information_schema.tables. Secondly there is an undocumented stored proc called sp_msForEachDb, which iterates through all the database one by one and runs the script that you want to, which you need to pass as a string input to it.
In your case, it seems that you want to join the information_schema.tables with sys.tables and list the tables for testDB database. Try the script below for that:
--Build a temp table to store the info
select * into #a
from INFORMATION_SCHEMA.TABLES it join sys.tables st
on st.name COLLATE SQL_Latin1_General_CP1_CI_AS= it.table_name COLLATE SQL_Latin1_General_CP1_CI_AS
where 1=0
insert into #a --This script runs for each database and populates the info into #a
EXECUTE master.sys.sp_MSforeachdb
'select * from INFORMATION_SCHEMA.TABLES it join [?].sys.tables st
on st.name COLLATE SQL_Latin1_General_CP1_CI_AS= it.table_name COLLATE SQL_Latin1_General_CP1_CI_AS
where it.TABLE_CATALOG = ''testdb'''
select * from #a

I'm in the middle of cleaning some servers. So currently this is my server (sorry for the lame diagram):
DatabaseServer00
-DatabaseA
-ViewA
-ViewB
-ViewC
-DatabaseB
-DatabaseC
I need to find if there is any sp/triger/function/etc... in DatabaseB/C that calls ViewA from DatabaseA.
I know that i can find dependencies in DatabaseA with this sp_depends
And I'm currently using this to search in other DB
Declare #Query varchar(max)
SET #Query = '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 ''%ViewA%'''
EXEC sp _MSforeachdb #Query
But.... This code right here ^ does not returns me that ViewB depends on ViewC
So i'm kind of out of queries to run. Thanks in advance for your help.
Take a look at the Information Schema Views, they should be able to help you in most cases except the Triggers, which you'll probably have to rely on sys.triggers
SELECT * FROM information_schema.routines ISR
WHERE CHARINDEX('dbo.ViewA', ISR.ROUTINE_DEFINITION) > 0
SELECT * FROM INFORMATION_SCHEMA.VIEWS ISW
WHERE CHARINDEX('dbo.ViewA', ISW.VIEW_DEFINITION) > 0
SELECT
DB_NAME() AS DatabasName
, so.name as TableName
, tr.name as TriggerName
, sc.text as TriggerText
FROM sys.triggers tr
INNER JOIN sys.objects so
ON tr.parent_id = so.object_id
INNER JOIN syscomments sc
ON sc.id = tr.object_id
WHERE CHARINDEX('dbo.ViewA', sc.text) > 0
I want to find all of the stored procedures where a particular table is being used. There are lots of stored procedures in the database, so it's not feasible to check each procedure.
Is there any way to use a search query so that I can find the stored procedures?
I have tried this code:
SELECT distinct so.name
FROM syscomments sc
INNER JOIN sysobjects so ON sc.id=so.id
WHERE sc.TEXT LIKE '% RejectionReason %'
Where RejectionReason is my table name, but it shows all procedures where RejectionReason is used as column name, so that doesn't work.
SELECT o.name, o.type_desc, p.name, p.type_desc
FROM sys.sql_dependencies d
INNER JOIN sys.objects o
ON d.object_id = o.object_id
INNER JOIN sys.objects p
ON d.referenced_major_id = p.object_id
AND o.name = 'RejectionReason'
or
SELECT o.name, t.TABLE_NAME, c.text
FROM syscomments c
JOIN sysobjects o
ON c.id = o.id
JOIN INFORMATION_SCHEMA.Tables t
ON c.text LIKE '%RejectionReason%'
or
EXEC sp_depends #objname = N'RejectionReason';
if none of those help you check this blog:
http://blog.sqlauthority.com/2010/02/04/sql-server-get-the-list-of-object-dependencies-sp_depends-and-information_schema-routines-and-sys-dm_sql_referencing_entities/
Try to use RedGate's free tool SQL Search.
Here is a piece of code hope it will work. Just changes the table name it depends upon your code
SELECT DISTINCT so.name
FROM syscomments sc INNER JOIN sysobjects so on sc.id=so.id
WHERE sc.text LIKE '%tablename%'
e.g.:
SELECT DISTINCT so.name
FROM syscomments sc INNER JOIN sysobjects so on sc.id=so.id
WHERE sc.text LIKE '%users%'
You will get the list of store procedures and the table relations.
As per MSDN sp_depends will be removed in future releases in case you are using that, you can use the following query instead:
SELECT referencing_schema_name, referencing_entity_name, referencing_id, referencing_class_desc, is_caller_dependent
FROM sys.dm_sql_referencing_entities ('dbo.TableName', 'OBJECT');
There are two possibilities I am aware of.
Firstly SQL Management Studio has an option to show Dependencies. Right-click on the Table and select View Dependencies However, this will not highlight usps where the tablename is embedded in dynamic SQL.
The second option is to right click on the database and select Generate Scripts. Follow the wizard and script all the usps to a new query window, then search that for the name of your table. This is more laborious, but will find all uses.
I guess this script shows all the dependent object of the table, including SPs.
USE MYDatabase
GO
DECLARE #TableName varchar(100)
SET #TableName = 'mytable'
SELECT
SourceSchema = OBJECT_SCHEMA_NAME(sed.referencing_id)
,SourceObject = OBJECT_NAME(sed.referencing_id)
,ReferencedDB = ISNULL(sre.referenced_database_name, DB_NAME())
,ReferencedSchema = ISNULL(sre.referenced_schema_name,
OBJECT_SCHEMA_NAME(sed.referencing_id))
,ReferencedObject = sre.referenced_entity_name
,ReferencedColumnID = sre.referenced_minor_id
,ReferencedColumn = sre.referenced_minor_name
FROM sys.sql_expression_dependencies sed
CROSS APPLY sys.dm_sql_referenced_entities(OBJECT_SCHEMA_NAME(sed.referencing_id)
+ '.' + OBJECT_NAME(sed.referencing_id), 'OBJECT') sre
WHERE sed.referenced_entity_name = #TableName
AND sre.referenced_entity_name = #TableName

This will return SP's and Views.
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 '%TableName%'
SysObjects stores basic information about all objects inside your database. It's useful for you to know because it tells us the name of each object and the type of the object.
SysComments stores the actual text (code) for your stored procedures and functions. It contains an ID field that maps back to the id field in SysObjects.
select so.name, text
from sysobjects so, syscomments sc
where so.id = sc.id
and text like '%RejectionReason%'
I am using the following SQL script to search for column names and text inside all stored procedures of your database. You can use it as well to find tables in stored procedures.
Specify the search term in variable #SearchFor(as you would use it in a LIKE expression, e.g. '%LastName%' to find columns and stored procedures containing LastName).
It will find column names in tables as well as text inside stored procedures. The script can even display the SP source code, if you set #SPNameOnlyto 0.
--
-- Purpose: Search field names in all tables, views stored procedures
--
DECLARE #SearchFor nvarchar(max)='%Search_SP_Or_Table_Or_View%' -- search for this string
DECLARE #SearchSP bit = 1 -- 1=search in SPs as well
DECLARE #DisplaySPSource bit = 1 -- 1=display SP source code
-- tables
if (#SearchSP=1) begin
(
select '['+c.table_Schema+'].['+c.table_Name+'].['+c.column_name+']' [schema_object],
t.table_type
from information_schema.columns c
left join information_schema.Tables t on c.table_name=t.table_name

I want to find out whether the table has an identity column or not. Table is unknown to me. I have not done the structure of the table. Using Query?
I am using Sql Server Compact Edition.
IF (OBJECTPROPERTY(OBJECT_ID('TABLE_NAME'), 'TableHasIdentity') = 1)
ObjectProperty is available starting sql server 2008 Reference:
OBJECTPROPERTY
This query returns a table's identity column name:
CREATE PROCEDURE dbo.usp_GetIdentity
#schemaname nvarchar(128) = 'dbo'
,#tablename nvarchar(128)
AS
BEGIN
SELECT OBJECT_NAME(OBJECT_ID) AS TABLENAME,
NAME AS COLUMNNAME,
SEED_VALUE,
INCREMENT_VALUE,
LAST_VALUE,
IS_NOT_FOR_REPLICATION
FROM SYS.IDENTITY_COLUMNS
WHERE OBJECT_NAME(OBJECT_ID) = #tablename
AND OBJECT_SCHEMA_NAME(object_id) = #schemaname
END
Then form the code side.
Call this stored procedure using the datareader role, then check datareader.hasrows(). If the condition value is true (1), then the table has identity column if set. If not then it doesn't have an identity column.
I know it's long time ago but i found this helpful
try this :
IF EXISTS (SELECT * from syscolumns where id = Object_ID(#TABLE_NAME) and colstat & 1 = 1)
BEGIN
-- Do your things
END
Any of the below queries can be used to check if an Identity Column is present in the table
1)
SELECT *
FROM sys.identity_columns
WHERE OBJECT_NAME(object_id) = 'TableName'
2)
SELECT *
FROM sys.identity_columns
WHERE object_id = (
SELECT id
FROM sysobjects
WHERE name = 'TableName'
)
I would just like to add this option as well as I think it is the simplest
SELECT COLUMNPROPERTY(OBJECT_ID('TableName'),'ColumnName','isidentity')
One way to do this would be to make use of the stored procedure sp_help. I.e:
sp_help MyTable
This will return a DataSet that has all the information you would need on the table. There is a specific Table that has information on identities.
I.e:
If it does not contain an identity field, the Identity column will say: "No identity column defined".
#Pranay: he said Compact Edition. Stored procedures aren't supported, and there is no sys.anything.
This is the call:
SELECT Count(*) FROM INFORMATION_SCHEMA.COLUMNS WHERE AUTOINC_INCREMENT IS NOT NULL AND TABLE_NAME='this_table'
It will return either 1 (true) or 0 (false).
...
declare #tblhasIdentCol bit = IF (IDENT_CURRENT( #dbName +'.'+ #schemaName +'.'+ #tableName ) IS NOT NULL , 1 , 0 )
You get numeric value if table has identity
Very simple answer would be to run this:
SELECT IDENT_CURRENT('TABLE-NAME')
This would give max value of identity column if exists, if the column doesn't exist, it gives 1 as result.
Based on max value, you can identify which column is having that and determine the identity column.
This the query that get u all the tableNames, columnnames of the table, and is_identity or not in the selected database
SELECT
sys.columns.name
, sys.tables.name
, is_identity
FROM sys.columns
INNER JOIN sys.tables ON sys.tables.object_id = sys.columns.object_id
AND sys.columns.is_identity = 1
CREATE FUNCTION dbo.fnTableHasIdentity(#Tbl sysname)
RETURNS TINYINT
BEGIN
RETURN OBJECTPROPERTY(OBJECT_ID(#Tbl), 'TableHasIdentity')
END
--As simple as that!
select t.name as TableName,c.name as ColumnName
from sys.identity_columns c
inner join sys.tables t on c.object_id = t.object_id
where t.name = 'TableName'
If you like me, needed to be able to do this for tables in an arbitrary database, then I found the following solution:
IF EXISTS (
SELECT 1
FROM [database name].sys.identity_columns AS id_col
INNER JOIN [database name].sys.objects
ON objects.object_id = id_col.object_id
INNER JOIN [database name].sys.schemas
ON schemas.schema_id = objects.schema_id
AND schemas.name = 'schema name'
WHERE OBJECT_NAME(id_col.object_id, DB_ID('database name')) = 'table name'
) SELECT 1 ELSE SELECT 0
you can get the 1 or 0 Boolean Form if the current table has identity Columns by using this
SELECT Count(Column_ID) FROM sys.identity_columns WHERE OBJECT_NAME(object_id) = 'tableName'
One way to list all Tables with their identity column if it exists
to get you desired table add at the end of the filter "and o.name='TableName'"
where Tbale Nam is the table you are looking for
SELECT o.[Name][TableName],i.[name][IdentityColName] FROM
sys.objects o
left outer join sys.identity_columns i on i.object_id=o.object_id
where o.type='U'
How to do a global search for a key word in all the Stored Proc's for a given DB?
I used the following but I am unable to get the desired results...
SELECT name
FROM sysobjects
WHERE id IN
(
SELECT id
FROM syscolumns
WHERE name = 'loadStatus' COLLATE SQL_Latin1_General_CP1_CI_AS
)
SELECT name
FROM sysobjects
WHERE id IN
(
SELECT id
FROM syscolumns
WHERE name like '%loadStatus%' COLLATE SQL_Latin1_General_CP1_CI_AS
)

Only sys.sql_modules contains the whole definition of the procedure. Other views like INFORMATION_SCHEMA.ROUTINES contain a truncated definition.
select object_name(o.object_id), m.*
from sys.sql_modules m
join sys.objects o on m.object_id = o.object_id
where o.type= 'P'
and m.definition like N'%<keyword>%'
Have a look at this link - http://www.sqlservercentral.com/scripts/T-SQL+Aids/31131/ and see if that helps.
The SP in the linked article was written by Prasad Bhogadi and is as follows:
CREATE PROCEDURE SEARCHFORSTRING #SEARCHSTRING VARCHAR(100)
AS
SELECT DISTINCT(sysobjects.name)
FROM
sysobjects,syscomments
WHERE
sysobjects.id = syscomments.id
AND
sysobjects.type = 'P'
AND
sysobjects.category=0
AND
CHARINDEX(#SEARCHSTRING ,syscomments.text)>0
You can use this to create an SP in your database or adapt it for a one-time query.
Im working on this large DB which has a lot of the business knowledge embedded in the SPs[I know!] and there is a lot of chaining between the SPs. i.e one stored proc calling another.
Im want to find out a list of stored procedures which update a particular column. How would I do that.
Using showplan_All as outlined in
SQL Table and column Parser for stored procedures doesnt work for me, because this is a shared dev db.
using a Sp from master db scanning system text as described is not feasible because I dont have access to the master db.
So how can I find this informaion?
From system view sys.sql_dependencies you can get dependencies at column level.
DECLARE #Schema SYSNAME
DECLARE #Table SYSNAME
DECLARE #Column SYSNAME
SET #Schema = 'dbo'
SET #Table = 'TableName'
SET #Column = 'ColumnName'
SELECT o.name
FROM sys.sql_dependencies AS d
INNER JOIN sys.all_objects AS o ON o.object_id = d.object_id
INNER JOIN sys.all_objects AS ro ON ro.object_id = d.referenced_major_id
INNER JOIN sys.all_columns AS c ON c.object_id = ro.object_id AND c.column_id = d.referenced_minor_id
WHERE (SCHEMA_NAME(ro.schema_id)=#Schema)
and o.type_desc = 'SQL_STORED_PROCEDURE'
and ro.name = #Table
and c.name = #Column
GROUP BY o.name
Have you tried this : EXEC sp_depends #objname = [table name of the column you are interested in].
So for example, if you had a column named Price in a table named Product, you would execute this: EXEC sp_depends #objname = N'Product'.
Simply executing this would give you list of all sps, views, etc which depend on that particular table.
I use this all the time as I work with a db which has over 400 tables :-)
sp_depends page on MSDN
Try something like this:
use YourDatabase;
select [Name]
from sys.procedures
where object_definition([object_id]) like '%YourColumnName%';
Obviously this has the potential to generate a lot of false positives depending on what the column is named but at least you will have a list of procedures to sift through.
Here's one that works in SQL 2000+; Note that as Andrew noted in his, you will get false positives depending on your column name, but it's a starting place:
SELECT DISTINCT o.Name
FROM syscomments c
JOIN sysobjects o ON c.ID = o.ID
WHERE c.Text LIKE '%ColumnName%'
ORDER BY o.Name
use msdb
go
select * from sysjobs j
inner join sysjobsteps s
on j.job_id=s.job_id
where command like '%HBR_INSTRUMENT%'
