I want to rename tables and views which are used in stored procedures. Is there any way to find and replace table names in stored procedures, maybe there is tool for ms sql server (i'm using ms sql server 2012).
SQL Server might not allow you to directly UPDATE the object definitions (Views and Stored Proceduress in your case) present in the System catalogs even after setting the 'Allow Updates' option to 1.
The following code will generate the required ALTER Script and you can run them manually after reviewing the definitions ([ModifiedDefinition] )or u can loop through each value of [ModifiedDefinition] and run it using sp_executesql.
SELECT
b.Name AS [ObjectName],
CASE WHEN b.type ='p' THEN 'Stored Procedure'
WHEN b.type ='v' THEN 'View'
ELSE b.TYPE
END AS [ObjectType]
,a.definition AS [Definition]
,Replace ((REPLACE(definition,'OLD Value','New Value')),'Create','ALTER') AS [ModifiedDefinition]
FROM sys.sql_modules a
JOIN
( select type, name,object_id
from sys.objects
where type in (
'p' -- procedures
,'v'--views
)
and is_ms_shipped = 0
)b
ON a.object_id=b.object_id
And as always, be careful with production data and take backups before performing bulk changes on object definitions!!
You can use DBvisualizer .. it pretty much works with all databases and with ms sql too, you can do all you mentioned by using this.
I answered this on another topic (https://stackoverflow.com/a/67728039/11165834) , I do it using the following script:
DECLARE #queryDef NVARCHAR(max)
WHILE EXISTS (
SELECT 1
FROM sys.sql_modules sm
JOIN sys.objects o ON sm.object_id = o.object_id
WHERE sm.definition LIKE '%TEXT_TO_REPLACE%'
AND o.type = 'V'
)
BEGIN
-- TO ALTER THE VIEW AUTOMATICALLY
SET #queryDef = ( SELECT TOP 1 Replace (Replace (sm.definition, 'CREATE VIEW', 'ALTER VIEW'),
'TEXT_TO_REPLACE',
'NEW_TEXT')
FROM sys.sql_modules sm
JOIN sys.objects o ON sm.object_id = o.object_id
WHERE sm.definition LIKE '%TEXT_TO_REPLACE%'
AND o.type = 'V')
EXEC (#queryDef)
END
I use it to replace procedures/views when I restore a backup from production into tests databases.
As #S.A said, be verry careful because is not a verry safe way.
Change the "o.type" and "Replace (sm.definition, 'CREATE VIEW', 'ALTER VIEW'" accordingly to your need

I have a script which searches through all the available databases (those I have access to) for a specific text in a procedure.
In my server, there are many databases (in my case about 150 databases), meaning that I get shown the results for all databases eventhough there are no results for most of them (about 90%).
Is there any way to avoid getting these empty result-queries?
You can use below code to check whether stored procedure contains a text in each database. If there are stored procedures in a database only, you will have resultset.
CREATE TABLE ##DatabasesContainingSP(dbname sysname, SPName SYSNAME);
EXECUTE master.sys.sp_MSforeachdb 'USE [?];
INSERT INTO ##DatabasesContainingSP
SELECT DISTINCT
db_name() as dbname, o.name AS Object_Name
FROM sys.sql_modules m
INNER JOIN
sys.objects o
ON m.object_id = o.object_id
WHERE m.definition Like ''%ABC%'';
'
IF EXISTS(SELECT * FROM ##DatabasesContainingSP )
begin
SELECT * FROM ##DatabasesContainingSP
end
GO
IF OBJECT_ID('tempdb..##DatabasesContainingSP' , 'U') IS NOT NULL
drop TABLE ##DatabasesContainingSP;
Thank you for the quick responses.
I managed to solve it by creating a table and adding insert into this table in the beginning of my generated and concatenated code, which solved the problem since when reading the table in the end, it only shows the inserted results.
With kind regards,

I am just starting creating some unit tests for my database.
If I have faked a table,
EXEC tSQLt.FakeTable
#TableName = 'dbo.[My Table]',
#Identity = 0,
#ComputedColumns = 0,
#Defaults = 0
Can I check if it has been faked?
Note that documentation on the FakeTable SP can be found here.
Motivation
I want to be able to do this as I imagine creating several stored procedures which populate these faked tables so I can perform tests.
However I do not want to handle faking the tables in the stored procedures (so I can call them multiple times entering different info each time).
I don't want to have the possibility that I forget to fake the table before adding the data (as would almost certainly cause me to fail my test).
tSQLt adds an extended property to a fake table to track the table it fakes. This is easily tested using the function tSQLt.Private_GetOriginalTableName:
SELECT tSQLt.Private_GetOriginalTableName('dbo','[My Table]')
This will return NULL if the table isn't faked.
If you want to do something more complex, you can query sys.extended_properties directly. See the contents of the tSQLt.class.sql script (in the tSQLt distribution) for the definition of tSQLt.Private_GetOriginalTableName.
You can check for the existence of the table at the beginning of your stored procedure(s).
If Not Exists ( Select 1 From Sys.Objects Where [Name] = 'YOURTABLENAME' And [Type] = 'U')
Begin
-- Your Create Table Statement Here
ENd
Based on your comments, the tool has to be doing something like this, using schema:
Create table dbo.MisterPositive ( test int )
Create table developers.MisterPositive (test Int )
-- Both statements below work
Select * From dbo.MisterPositive
Select * From developers.MisterPositive
-- Use this to look for existence prior
Select 1 from sys.objects
Inner join sys.schemas ON sys.objects.schema_id = sys.schemas.schema_id
where sys.objects.[Name] = 'MisterPositive' And sys.schemas.name = 'dbo'
Select 1 from sys.objects
Inner join sys.schemas ON sys.objects.schema_id = sys.schemas.schema_id
where sys.objects.[Name] = 'MisterPositive' And sys.schemas.name = 'Developers'
So yours would be
If Not Exists ( Select 1 from sys.objects
Inner join sys.schemas ON sys.objects.schema_id = sys.schemas.schema_id
where sys.objects.[Name] = 'YOURTABLE' And sys.schemas.[Name] = 'tSQLt' )
Begin
-- create table here
End
Is there any query in SQL server 2005 that returns the list of Stored procedures in the particular database along with the name of databases whose objects are getting used in the stored procedure.
That is how to get all procedure names:
select *
from DatabaseName.information_schema.routines
where routine_type = 'PROCEDURE'
I will check now, if there is any way to check their code for table names.
you can use this query
it will show all dependencies even to the columns
SELECT
--SP, View, or Function
ReferencingName = o.name,
ReferencingType = o.type_desc,
--Referenced Field
ref.referenced_database_name, --will be null if the DB is not explicitly called out
ref.referenced_schema_name, --will be null or blank if the DB is not explicitly called out
ref.referenced_entity_name,
ref.referenced_minor_name
FROM sys.objects AS o
cross apply sys.dm_sql_referenced_entities('dbo.' + o.name, 'Object') ref
where o.type = 'p'
-- for other database object types use below line
-- o.type in ('FN','IF','V','P','TF')
works for single database
select *
from information_schema.routines
where routine_type = 'PROCEDURE'
This is not a simple thing to do reliably in SQL Server 2005. You might want to look at commercial products such as ApexSQL Clean or SQL Dependency Tracker.
In SQL Server 2008 you could try using the sys.sql_expression_dependencies dynamic management view. For example,
select
quotename(s.name) + N'.' + quotename(o.name) as ProcedureName,
ed.referenced_server_name,
ed.referenced_database_name,
ed.referenced_schema_name,
ed.referenced_entity_name
from sys.sql_expression_dependencies ed
inner join sys.objects o on o.object_id = ed.referencing_id
inner join sys.schemas s on s.schema_id = o.schema_id
where
o.type = 'P'
Hope this helps,

I have created a SQL CLR trigger with the follow SQL:
GO
CREATE TRIGGER AuditAccountsTable
ON [dbo].[Accounts]
FOR INSERT,DELETE,UPDATE
AS
EXTERNAL NAME namespace.Triggers.AuditTrigger
I am trying to query:
select * from sys.triggers
Is there a way to find the: EXTERNAL NAME namespace.Triggers.AuditTrigger on the trigger from querying in the DB?
I can't be sure as I don't have a place to test this, but does the text column returned below get you close to what you're looking for?
select t.name, c.text
from sys.triggers t
inner join sys.syscomments c
on t.object_id = c.id
where t.type_desc = 'CLR_TRIGGER'
Unlike T-SQL "modules" such as Stored Procedures and Functions, the SQLCLR T-SQL wrapper objects do not have their CREATE statements stored in the database. This is why you cannot access them via sys.sql_modules, OBJECT_DEFINITION, or the deprecated-since-SQL-Server-2005-and-should-not-be-used sys.syscomments. This is why SQLCLR Stored Procedures and Functions need to have their parameter default values stored in sys.parameters
Instead, CREATE statements for SQLCLR T-SQL wrapper objects are inferred from meta-data, just like Indexes, Primary Keys, Foreign Keys, etc.
You can get all of the parts of the CREATE TRIGGER statement from the following query:
SELECT OBJECT_SCHEMA_NAME(st.[object_id]) AS [SchemaName],
st.[name] AS [TriggerName],
OBJECT_SCHEMA_NAME(st.parent_id) AS [ParentSchemaName],
OBJECT_NAME(st.parent_id) AS [ParentName],
st.is_instead_of_trigger,
SUBSTRING((
SELECT N', ' + ste.[type_desc]
FROM sys.trigger_events ste
WHERE ste.[object_id] = st.[object_id]
FOR XML PATH ('')
), 3, 500) AS [Actions],
QUOTENAME(sa.name) AS [AssemblyName],
QUOTENAME(sam.assembly_class) AS [AssemblyClass],
QUOTENAME(sam.assembly_method) AS [AssemblyMethod]
FROM sys.triggers st
INNER JOIN sys.assembly_modules sam
ON sam.[object_id] = st.[object_id]
INNER JOIN sys.assemblies sa
ON sa.[assembly_id] = sam.[assembly_id]
WHERE st.parent_class = 1; --- OBJECT_OR_COLUMN
Is there a way to know what are the tables used by one stored procedure by doing an SQL query?
Best regards, and thanks for the help.
P.S.: I'm using SQL Server 2005.
This article on TechRepublic
Finding dependencies in SQL Server 2005
describes a way to do that:
This tutorial will show how you can
write a procedure that will look up
all of the objects that are dependent
upon other objects.
Here is the code to create the system stored procedure for finding object dependencies:
USE master
GO
CREATE PROCEDURE sp_FindDependencies
(
#ObjectName SYSNAME,
#ObjectType VARCHAR(5) = NULL
)
AS
BEGIN
DECLARE #ObjectID AS BIGINT
SELECT TOP(1) #ObjectID = object_id
FROM sys.objects
WHERE name = #ObjectName
AND type = ISNULL(#ObjectType, type)
SET NOCOUNT ON ;
WITH DependentObjectCTE (DependentObjectID, DependentObjectName, ReferencedObjectName, ReferencedObjectID)
AS
(
SELECT DISTINCT
sd.object_id,
OBJECT_NAME(sd.object_id),
ReferencedObject = OBJECT_NAME(sd.referenced_major_id),
ReferencedObjectID = sd.referenced_major_id
FROM
sys.sql_dependencies sd
JOIN sys.objects so ON sd.referenced_major_id = so.object_id
WHERE
sd.referenced_major_id = #ObjectID
UNION ALL
SELECT
sd.object_id,
OBJECT_NAME(sd.object_id),
OBJECT_NAME(referenced_major_id),
object_id
FROM
sys.sql_dependencies sd
JOIN DependentObjectCTE do ON sd.referenced_major_id = do.DependentObjectID
WHERE
sd.referenced_major_id <> sd.object_id
)
SELECT DISTINCT
DependentObjectName
FROM
DependentObjectCTE c
END
This procedure uses a Common Table
Expression (CTE) with recursion to
walk down the dependency chain to get
to all of the objects that are
dependent on the object passed into
the procedure. The main source of data
comes from the system view
sys.sql_dependencies, which contains
dependency information for all of your
objects in the database.
Try sp_depends, although you should probably recompile the stored procedure to update the statistics in the database.
Look up sp_depends system stored proc.
I think that as long as the stored procedure and the tables are all in the same database then you can right click on the procedure in SSMS and click "View Dependencies". I don't know the query behind the dialog though...
As others indicated you can use the Dependancies stored procedures; however, in my experience and this was back on SQL Server 2000, the depandancies were not always reliable. In some cases they weren't being updated. You can always go to the sysComments table assuming your schema is not encrypted.
declare #crlfSearch varchar(max),#objectSearch varchar(max),#escapeSearch varchar(max)
set #crlfSearch=('%bid' + char(13)+'%')
set #objectSearch='%bid %'
set #escapeSearch ='%[[]Bid]%'
select distinct so.name
from syscomments sc
inner join sysobjects so
on sc.id=so.id
where text like #objectSearch or text like #crlfSearch
or text like #escapesearch
This query looks for three common cases you might have to add some but basically we find where the table name has a space after it, (This helps to limit cases where the table name is part of another table name), Has a return at the end of it, or is escaped within brackets.
