Is there a query to get the list of tables on which my table depends? I have already tried sys.sql_expression_dependencies, sys.dm_sql_referencing_entities, sp_depends, information_schema.routines.
This gives the objects which depend on my table. These are the queries I have tried:
sp_depends 'dbo.buyer'
SELECT *
FROM information_schema.routines ISR
WHERE CHARINDEX('dbo.buyer', ISR.ROUTINE_DEFINITION) > 0
SELECT OBJECT_NAME(referencing_id),* FROM sys.sql_expression_dependencies
WHERE referencing_id = OBJECT_ID('dbo.buyer')
SELECT OBJECT_NAME(referencing_id),* FROM
ims.sys.sql_expression_dependencies
WHERE referenced_id = OBJECT_ID('ims.dbo.buyer');
SELECT referencing_schema_name, referencing_entity_name,
referencing_id, referencing_class_desc, is_caller_dependent
FROM sys.dm_sql_referencing_entities ('dbo.buyer', 'OBJECT')
try this
SELECT DISTINCT t.name
FROM sys.foreign_key_columns as fk
INNER JOIN sys.tables as t
ON fk.referenced_object_id = t.object_id
INNER JOIN sys.tables as t2
ON fk.parent_object_id = t2.object_id
WHERE t2.name = 'yourTableName'
Go through the following link
https://learn.microsoft.com/en-us/sql/relational-databases/tables/view-the-dependencies-of-a-table
You can get details of
1. Object that depends on
2. Object on which {table} depends

With SQL Server 2016 supporting Temporal Tables I wonder if there is a way to determine if a table is currently temporal? Something like
select * from sys.objects where object_id('dbo.MyTable', 'u') = parent_object_id and type_desc = "SYSTEM_VERSIONED"
SELECT temporal_type
FROM sys.tables
WHERE object_id = OBJECT_ID('dbo.MyTable', 'u')
0 = NON_TEMPORAL_TABLE
1 = HISTORY_TABLE
2 = SYSTEM_VERSIONED_TEMPORAL_TABLE
Documentation
Another way of listing temporal tables with their history tables together is given in this SQL tutorial as List Temporal and History Tables in a SQL Server Database
select
t.object_id,
t.name,
t.temporal_type,
t.temporal_type_desc,
h.object_id,
h.name,
h.temporal_type,
h.temporal_type_desc
from sys.tables t
inner join sys.tables h on t.history_table_id = h.object_id
Here is a simple answer to the original basic question:
SELECT *
FROM sys.tables
WHERE name = 'MyTable'
AND schema_id = SCHEMA_ID('dbo')
AND temporal_type_desc = 'SYSTEM_VERSIONED_TEMPORAL_TABLE'
And here is a similar query looking for the actual system managed history table:
SELECT h.* FROM sys.tables p
INNER JOIN sys.tables h
ON p.history_table_id = h.object_id
WHERE p.name = 'MyTable'
AND p.schema_id = SCHEMA_ID('dbo')
AND p.temporal_type_desc = 'SYSTEM_VERSIONED_TEMPORAL_TABLE';
This query will give you the system versioned tables, the associated history tables, the retention policy, and whether the retention policy is enabled at the database level.
From Microsoft Docs
SELECT DB.is_temporal_history_retention_enabled,
SCHEMA_NAME(T1.schema_id) AS TemporalTableSchema,
T1.name as TemporalTableName, SCHEMA_NAME(T2.schema_id) AS HistoryTableSchema,
T2.name as HistoryTableName,T1.history_retention_period,
T1.history_retention_period_unit_desc
FROM sys.tables T1
OUTER APPLY (select is_temporal_history_retention_enabled from sys.databases
where name = DB_NAME()) AS DB
LEFT JOIN sys.tables T2
ON T1.history_table_id = T2.object_id WHERE T1.temporal_type = 2
I have a database and a lot of tables inside it. I wrote some information into the each table and column's decription part. And now using query i want to see all table and columns descriptions.
Note: DATABASE -> ms sql server
Can you please help me ?
You can see that using INFORMATION_SCHEMA
To get columns for each table you can do:
SELECT * FROM INFORMATION_SCHEMA.COLUMNS
To get table information you can do:
SELECT * FROM INFORMATION_SCHEMA.TABLES
Check this query:
SELECT
t.name AS TableName
, td.value AS TableDescription
, c.name AS ColumnName
, cd.value AS ColumnDescription
FROM sys.tables t
INNER JOIN sys.columns c ON t.object_id = c.object_id
LEFT JOIN sys.extended_properties td
ON td.major_id = t.object_id
AND td.minor_id = 0
AND td.name = 'MS_Description'
LEFT JOIN sys.extended_properties cd
ON cd.major_id = t.object_id
AND cd.minor_id = c.column_id
AND cd.name = 'MS_Description'
select * from INFORMATION_SCHEMA.TABLES
select * from INFORMATION_SCHEMA.COLUMNS
select * from user_col_comments;
This will display all tables's column with comments for the logged in user.
select * from user_col_comments where table_name = '<table name>';
This will display specified tables's column with comments for the logged in user.
desc table_name query is used to describe the table
I'm using the following t-sql code:
USE [my_database]
SELECT DISTINCT so.name
FROM syscomments sc
INNER JOIN sysobjects so ON sc.id=so.id
WHERE sc.TEXT LIKE '%table_name%'
in order to show all the Stored Procedures that use the table table_name.
I want do this work for all tables in my database.
How can I perform this task and organize the output?
This uses information schema for both tables, and stored procedures. You can change or get rid of ROUTINE_TYPE condition to add functions, and you can change table type to return views.
This answer produces its results by checking what tables a stored procedure depends on. I think this will be a much more accurate result then checking if a name is in the query text. If the procedure refers to a table in a comment section, then this result will not be returned in the first query, but will be in the second and other answers given.
SELECT t.TABLE_NAME, s.ROUTINE_NAME
FROM INFORMATION_SCHEMA.TABLES t
INNER JOIN INFORMATION_SCHEMA.ROUTINES s ON
s.ROUTINE_NAME IN (SELECT referencing_entity_name
FROM sys.dm_sql_referencing_entities(TABLE_SCHEMA + '.' + TABLE_NAME, 'OBJECT'))
AND s.ROUTINE_TYPE = 'PROCEDURE'
WHERE t.TABLE_TYPE = 'BASE TABLE'
edit: Here's how to get the dependencies without the function. (I like this method the best)
SELECT DISTINCT t.name [TableName], p.name [ProcedureName]
FROM sys.objects t
LEFT JOIN sys.sql_dependencies d ON
d.referenced_major_id = t.object_id
LEFT JOIN sys.objects p ON
p.object_id = d.object_id
AND p.type = 'p'
WHERE t.type = 'u'
If your specific use is to just find any string that matches a table name, below will work:
SELECT t.TABLE_NAME, s.ROUTINE_NAME
FROM INFORMATION_SCHEMA.TABLES t
INNER JOIN INFORMATION_SCHEMA.ROUTINES s
ON CHARINDEX(t.TABLE_NAME, s.ROUTINE_DEFINITION) > 0
AND s.ROUTINE_TYPE = 'PROCEDURE'
WHERE t.TABLE_TYPE = 'BASE TABLE'
You could do a JOIN on LIKE:
select * from INFORMATION_SCHEMA.TABLES t
join
(
SELECT DISTINCT so.name
FROM syscomments sc
INNER JOIN sysobjects so ON sc.id=so.id
) x on x.name like '%' + t.TABLE_NAME + '%'
Note that your query doesn't restrict to procs - you'll also get views, defaults, and other objects too. If you just want procs, you can add where so.xtype = 'P' to your inner query.
Another version that uses sys tables only:
select t.name as TableName, p.name as SPName
from sys.objects t
join sys.syscomments c
on c.text like '%' + t.name + '%'
join sys.objects p
on p.object_id = c.id
where t.type = 'U' -- user table
and p.type = 'P' -- procedure
You can also use the built in function that's been around at least since SQL 2005 and works for tables, views, and stored procedures. I get the same number of results as Daniel's answer above when checking dependencies on a table in a fairly enterprisy database.
sp_depends [TableName]
sp_depends [TableName.Column]
sp_depends [StoredProcedureName]

I need an sql query to enumerate all views (I only need the view names) of a specific database in SQL Server 2005.
To finish the set off (with what has already been suggested):
SELECT * FROM sys.views
This gives extra properties on each view, not available from sys.objects (which contains properties common to all types of object) or INFORMATION_SCHEMA.VIEWS. Though INFORMATION_SCHEMA approach does provide the view definition out-of-the-box.
SELECT SCHEMA_NAME(schema_id) AS schema_name
,name AS view_name
,OBJECTPROPERTYEX(OBJECT_ID,'IsIndexed') AS IsIndexed
,OBJECTPROPERTYEX(OBJECT_ID,'IsIndexable') AS IsIndexable
FROM sys.views
SELECT *
FROM sys.objects
WHERE type = 'V'
Run this adding DatabaseName in where condition.
SELECT TABLE_NAME, ROW_NUMBER() OVER(ORDER BY TABLE_NAME) AS 'RowNumber'
FROM INFORMATION_SCHEMA.VIEWS
WHERE TABLE_CATALOG = 'DatabaseName'
or remove where condition adding use.
use DataBaseName
SELECT TABLE_NAME, ROW_NUMBER() OVER(ORDER BY TABLE_NAME) AS 'RowNumber'
FROM INFORMATION_SCHEMA.VIEWS
select v.name
from INFORMATION_SCHEMA.VIEWS iv
join sys.views v on v.name = iv.Table_Name
where iv.Table_Catalog = 'Your database name'
Some time you need to access with schema name,as an example you are using AdventureWorks Database you need to access with schemas.
SELECT s.name +'.'+v.name FROM sys.views v inner join sys.schemas s on s.schema_id = v.schema_id
Necromancing.
Since you said ALL views, technically, all answers to date are WRONG.
Here is how to get ALL views:
SELECT
sch.name AS view_schema
,sysv.name AS view_name
,ISNULL(sysm.definition, syssm.definition) AS view_definition
,create_date
,modify_date
FROM sys.all_views AS sysv
INNER JOIN sys.schemas AS sch
ON sch.schema_id = sysv.schema_id
LEFT JOIN sys.sql_modules AS sysm
ON sysm.object_id = sysv.object_id
LEFT JOIN sys.system_sql_modules AS syssm
ON syssm.object_id = sysv.object_id
-- INNER JOIN sys.objects AS syso ON syso.object_id = sysv.object_id
WHERE (1=1)
AND (sysv.type = 'V') -- seems unnecessary, but who knows
-- AND sch.name = 'INFORMATION_SCHEMA'
/*
AND sysv.is_ms_shipped = 0
AND NOT EXISTS
(
SELECT * FROM sys.extended_properties AS syscrap
WHERE syscrap.major_id = sysv.object_id
AND syscrap.minor_id = 0
AND syscrap.class = 1
AND syscrap.name = N'microsoft_database_tools_support'
)
*/
ORDER BY
view_schema
,view_name
This is old, but I thought I'd put this out anyway since I couldn't find a query that would give me ALL the SQL code from EVERY view I had out there. So here it is:
SELECT SM.definition
FROM sys.sql_modules SM
INNER JOIN sys.Objects SO ON SM.Object_id = SO.Object_id
WHERE SO.type = 'v'
To discover all triggers in any given MS SQL Server database, I'm currently querying the sysobjects table (which is fine because it works in MS SQL Server 2000 which I have to support) e.g.
SELECT R1.name AS trigger_name,
T1.name AS trigger_parent_table_name
FROM sysobjects AS R1
INNER join sysobjects AS T1
ON R1.parent_obj = T1.id
WHERE R1.xtype = 'tr';
This gives me a reduced list of trigger names and for each I can use
EXEC sp_helptext 'trigger_name_here'
to find the definition. That works fine for databases where only the default dbo schema is used.
I now have a MS SQL Server 2005 database which uses multiple schemas. What is the best way of discovering the schema for each trigger?
You are looking for the parent object for a trigger so it will always be a table. In sys.tables (system view) you get the schema_id and with it you can go sys.schemas (system view too) to get the schema's name.
Hope this helps.

EDIT:
The code:
SELECT sys.objects.name AS [trigger],
sys.tables.name AS [table],
sys.objects.type,
sys.schemas.name AS [schema]
FROM sys.schemas RIGHT OUTER JOIN
sys.tables ON sys.schemas.schema_id = sys.tables.schema_id RIGHT OUTER JOIN
sys.objects ON sys.tables.object_id = sys.objects.parent_object_id
WHERE sys.objects.type = 'tr'
This is is with sys.tables but you can do it with only sys.objects, this is a general select to look for parents and schemas:
SELECT O.name, O.type, S.name AS [schema],
OP.name AS parent_name, OP.type AS parent_type, SP.name AS parent_schema
FROM sys.schemas AS SP RIGHT OUTER JOIN
sys.objects AS OP ON SP.schema_id = OP.schema_id RIGHT OUTER JOIN
sys.objects AS O LEFT OUTER JOIN
sys.schemas AS S ON O.schema_id = S.schema_id ON OP.object_id = O.parent_object_id
