I want to find all tables used in stored procedures but it only gives me the tables that are in the database that I'm just using. Is there a solution to find all tables used in stored procedures, which are in other databases (in the same server)?
I try this:
SELECT DISTINCT p.name AS proc_name, t.name AS table_name
FROM sys.sql_dependencies d
INNER JOIN sys.procedures p ON p.object_id = d.object_id
INNER JOIN sys.tables t ON t.object_id = d.referenced_major_id
WHERE p.name like '%sp_example%'
ORDER BY proc_name, table_name
The procedures I need to analyze contain tables from different databases, but the code above gives me only results from one database.
First of all, sys.sql_dependencies is deprecated. Instead, you should use sys.sql_expression_dependencies. In it, you will find 4-part names of referenced objects (this includes objects referenced via linked server, for example).
Second, any object_id in SQL Server only makes sense within its database. If you are looking for anything outside of your current DB, don't join tables by these identifiers - use object names instead.

I saw some answers about search text in stored procedures name, Id and etc. But I don't find out that what is the good way to find all stored procedures including the SQL of their body
More info: I have a table called X; I wand to drop it and I want to be sure that it has not been used in stored procedures.
this will find all procedures, functions, triggers, etc with the text Xin it
SELECT DISTINCT
o.name AS Object_Name,
o.type_desc,
m.*
FROM sys.sql_modules m
INNER JOIN sys.objects o ON m.object_id = o.object_id
WHERE m.definition Like '%X%'
It is easy to alter so you only get procedures, or whatever you need
I want to know if a certain table dbo.person is being used in any of the database views in my database. There are a lot of views in this database.
I could right click each view "Script View as --> CREATE To" to see the SQL that was used to build this view but this will take a long time.
I am wondering if there is any way to query all of these "create view as" scripts to see if any of them mention my table dbo.person.
I hope this is clear.
You can query the system catalog for views (and use sql_modules to get the view definition) then use the system view sys.sql_expression_dependencies to find which of these views reference dbo.Person:
SELECT ViewName = QUOTENAME(OBJECT_SCHEMA_NAME(v.[object_id])) + '.' + QUOTENAME(v.Name),
m.[Definition]
FROM sys.views AS v
INNER JOIN sys.sql_modules AS m
ON m.[object_id] = v.[object_id]
WHERE EXISTS
( SELECT 1
FROM sys.sql_expression_dependencies AS d
WHERE d.Referenced_id = OBJECT_ID(N'dbo.Person', 'U')
AND v.[object_id] = d.referencing_id
)
ORDER BY ViewName;
There are some small issues with sys.sql_expression_dependencies, but I would still be more inclined to use this than to search for '%person%', since this could bring back 10s, or 100s of extra results, any time a table that contains person (e.g. dbo.PersonAddress) is referenced, or person is used as an alias (SELECT Forename + surname AS Person) etc. It really depends whether you are looking for something that is going to be accurate most of the time, but may, on occasion miss a reference, or whether you need a catch all solution that will bring back extra results.
You could try
select * from INFORMATION_SCHEMA.VIEWS
where VIEW_DEFINITION like '%Person%'
You might need to change the WHERE to dbo.person or [Person]
For a more detailed string search on SQL Server database object definitions please refer to SQL Object Where Used List script
You can simply call like
exec SearchInObjectsText 'name'
and it will return procedures, functions, views, etc where the text "name" is used
I know this doesn't answer the question directly, but it answers the need. I use a third party add-in called SQLSearch from redgate. It's free and I'm not an employee, so this isn't a "plug" of any kind.
I normally use this SQL to look in definitions. I didn't filter on VIEWS just in case it is used somewhere else.
SELECT
so.name, so.type, sm.Definition
FROM
sys.objects AS so INNER JOIN sys.sql_modules AS sm ON so.object_id = sm.object_id
WHERE
sm.Definition LIKE N'%dbo.person%'
ORDER BY so.name
Please query Information_Schema.View_Table system views
select * from INFORMATION_SCHEMA.VIEW_TABLE_USAGE where TABLE_NAME = 'Emp'
Try this
SELECT DISTINCT m.definition, 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 '%person%'
and type_desc = 'VIEW'
Does there exist a system stored procedure that lists the names of all tables in a SQL Server 2000 database and per table the names of all columns in that table? I want to export this data to a file for documentation.
I don't know if a system stored procedure exists, but I use this:
SELECT SysObjects.[Name] as TableName,
SysColumns.[Name] as ColumnName,
SysTypes.[Name] As DataType,
SysColumns.[Length] As Length
FROM
SysObjects INNER JOIN SysColumns
ON SysObjects.[Id] = SysColumns.[Id]
INNER JOIN SysTypes
ON SysTypes.[xtype] = SysColumns.[xtype]
WHERE SysObjects.[type] = 'U'
ORDER BY SysObjects.[Name]
In SQL-Server 2005+ you can do it using system views sys.columns and sys.tables
SELECT t.name TableName, c.name ColumnName
FROM sys.tables t
JOIN sys.columns c ON t.object_id=c.object_id
And you can also query the INFORMATION_SCHEMA.COLUMNS view.
It's also safer to use this view. Microsoft says this about the view "Querying the system tables directly may not provide accurate information if system tables are changed in future releases. These views provide an internal, system table-independent view of the SQL Server meta data. Information schema views allow applications to work properly even though significant changes have been made to the system tables."
Is there any way to know if a particular table is being referenced by any Views or not.I used the below code which gives only SP's and function names:
select * from sys.objects p inner join sys.sql_modules m
on p.object_id = m.object_id
where m.definition like '%abc%'
Please help!!!
select *
from INFORMATION_SCHEMA.VIEWS
where VIEW_DEFINITION like '%abc%'
First, your query gives views in the result set (I tried it on AdentureWorks2012 -> Production.Product table):
If you're using SQL Server 2008 or above, you can use the sys.sql_expression_dependencies catalog view. For example:
SELECT
referencing_object_name = o.name,
referencing_object_type_desc = o.type_desc,
referenced_object_name = referenced_entity_name,
referenced_object_type_desc = o1.type_desc
FROM sys.sql_expression_dependencies sed
INNER JOIN sys.objects o
ON sed.referencing_id = o.[object_id]
LEFT OUTER JOIN sys.objects o1
ON sed.referenced_id = o1.[object_id]
WHERE referenced_entity_name = 'YourTable'
It will give you nice look on each by-name dependency on a user-defined entity
For column level dependencies you can use the sys.dm_sql_referenced_entities function
Hope this helps
If you need to find database objects (e.g. tables, columns, triggers) by name - have a look at the FREE Red-Gate tool called SQL Search which does this - it searches your entire database for any kind of string(s).
It's a great must-have tool for any DBA or database developer - did I already mention it's absolutely FREE to use for any kind of use??
If that doesn't fit your bill - you could also check out the sysdepends catalog view in SQL Server - it lists what objects depend on what (see details in the MSDN docs).
To find out what objects depend on a given table, you could use something like:
SELECT
id,
OBJECT_NAME(ID)
FROM sys.sysdepends
WHERE depid = OBJECT_ID('YourTable')
That should give you a list of all objects depending on that table (or view or whatever you're checking)
Does anybody know of a query from system tables or views to get a list of views that use a certain field in a SQL Server database?
SELECT *
FROM
sys.sql_modules m
JOIN
sys.views v ON m.object_id = v.object_id
WHERE
m.definition LIKE '%MyTable%' --or '%MyField%'
INFORMATION_SCHEMA views and legacy syscomments are unreliable for large view definition (or any definition) because they have nvarchar(4000) fields. sys.sql_modules uses nvarchar(max).
They should not be used
sys.sql_expression_dependencies may be an alternative but is more complex to use.
