[sql] How to identify all stored procedures referring a particular table

I created a table on development environment for testing purpose and there are few sp's which are refreing this table. Now I have have to drop this table as well as identify all sp's which are referring this table. I am facing difficulty to find list of all sp's. Please suggest some query by assuming that the table name is 'x' and database is sql server 2005.

This useful query also works if you are using Azure SQL / Synapse Anlaytics

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 '%Table_Name%'

SELECT DISTINCT OBJECT_NAME(OBJECT_ID),
object_definition(OBJECT_ID)
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%' + 'table_name' + '%'

GO

This will work if you have to mention the table name.

Try This

   SELECT DISTINCT so.name
    FROM syscomments sc
    INNER JOIN sysobjects so ON sc.id=so.id
    WHERE sc.TEXT LIKE '%your table name%'

You have basically 2 options:

----Option 1

SELECT DISTINCT so.name
FROM syscomments sc
INNER JOIN sysobjects so ON sc.id=so.id
WHERE sc.TEXT LIKE '%tablename%'

----Option 2

SELECT DISTINCT o.name, o.xtype
FROM syscomments c
INNER JOIN sysobjects o ON c.id=o.id
WHERE c.TEXT LIKE '%tablename%'

These 2 queries will get you all the stored procedures that are referring the table you desire. This query relies on 2 sys tables which are sysobjects and syscomments. The sysobjects is where all of your DB object names are stored this includes the stored procedures.

The syscomments contains the text for all of your procedures.

If you query: SELECT * FROM syscomments

You'll have a table containing the id which is the mapping to the sysobjects table with the text contained in the stored procedures as the last column.

SELECT
    o.name
FROM
    sys.sql_modules sm
INNER JOIN sys.objects o ON
    o.object_id = sm.object_id
WHERE
    sm.definition LIKE '%<table name>%'

Just keep in mind that this will also turn up SPs where the table name is in the comments or where the table name is a substring of another table name that is being used. For example, if you have tables named "test" and "test_2" and you try to search for SPs with "test" then you'll get results for both.

sometimes above queries will not give correct result, there is built in stored procedure available to get the table dependencies as:

EXEC sp_depends @objname = N'TableName';

A non-query way would be to use the Sql Server Management Studio.

Locate the table, right click and choose "View dependencies".

EDIT

But, as the commenters said, it is not very reliable.

In management studio you can just right click to table and click to 'View Dependencies'

than you can see a list of Objects that have dependencies with your table :

The following works on SQL2008 and above. Provides a list of both stored procedures and functions.

select distinct [Table Name] = o.Name, [Found In] = sp.Name, sp.type_desc
  from sys.objects o inner join sys.sql_expression_dependencies  sd on o.object_id = sd.referenced_id
                inner join sys.objects sp on sd.referencing_id = sp.object_id
                    and sp.type in ('P', 'FN')
  where o.name = 'YourTableName'
  order by sp.Name

The query below works only when searching for dependencies on a table and not those on a column:

EXEC sp_depends @objname = N'TableName';

However, the following query is the best option if you want to search for all sorts of dependencies, it does not miss any thing. It actually gives more information than required.

 select distinct
        so.name
        --, text 
  from 
       sysobjects so, 
       syscomments sc 
  where 
     so.id = sc.id 
     and lower(text) like '%organizationtypeid%'
  order by so.name

The following query will fetch all Stored Procedure names and the corresponding definition of those SP's

select 
   so.name, 
   text 
from 
   sysobjects so, 
   syscomments sc 
where 
   so.id = sc.id 
   and UPPER(text) like '%<TABLE NAME>%'
