# Retrieve information about the database
# Retrieve a List of all Stored Procedures
The following queries will return a list of all Stored Procedures in the database, with basic information about each Stored Procedure:
SELECT *
FROM INFORMATION_SCHEMA.ROUTINES
WHERE ROUTINE_TYPE = 'PROCEDURE'
The ROUTINE_NAME, ROUTINE_SCHEMA and ROUTINE_DEFINITION columns are generally the most useful.
SELECT *
FROM sys.objects
WHERE type = 'P'
SELECT *
FROM sys.procedures
Note that this version has an advantage over selecting from sys.objects since it includes the additional columns is_auto_executed, is_execution_replicated, is_repl_serializable, and skips_repl_constraints.
SELECT *
FROM sysobjects
WHERE type = 'P'
Note that the output contains many columns that will never relate to a stored procedure.
The next set of queries will return all Stored Procedures in the database that include the string 'SearchTerm':
SELECT o.name
FROM syscomments c
INNER JOIN sysobjects o
ON c.id=o.id
WHERE o.xtype = 'P'
AND c.TEXT LIKE '%SearchTerm%'
SELECT p.name
FROM sys.sql_modules AS m
INNER JOIN sys.procedures AS p
ON m.object_id = p.object_id
WHERE definition LIKE '%SearchTerm%'
# Get the list of all databases on a server
Method 1: Below query will be applicable for SQL Server 2000+ version (Contains 12 columns)
SELECT * FROM dbo.sysdatabases
Method 2: Below query extract information about databases with more informations (ex: State, Isolation, recovery model etc.)
Note: This is a catalog view and will be available SQL SERVER 2005+ versions
SELECT * FROM sys.databases
Method 3: To see just database names you can use undocumented sp_MSForEachDB
EXEC sp_MSForEachDB 'SELECT ''?'' AS DatabaseName'
Method 4: Below SP will help you to provide database size along with databases name , owner, status etc. on the server
EXEC sp_helpdb
Method 5 Similarly, below stored procedure will give database name, database size and Remarks
EXEC sp_databases
# Count the Number of Tables in a Database
This query will return the number of tables in the specified database.
USE YourDatabaseName
SELECT COUNT(*) from INFORMATION_SCHEMA.TABLES
WHERE TABLE_TYPE = 'BASE TABLE'
Following is another way this can be done for all user tables with SQL Server 2008+. The reference is here (opens new window).
SELECT COUNT(*) FROM sys.tables
# Database Files
Display all data files for all databases with size and growth info
SELECT d.name AS 'Database',
d.database_id,
SF.fileid,
SF.name AS 'LogicalFileName',
CASE SF.status & 0x100000
WHEN 1048576 THEN 'Percentage'
WHEN 0 THEN 'MB'
END AS 'FileGrowthOption',
Growth AS GrowthUnit,
ROUND(((CAST(Size AS FLOAT)*8)/1024)/1024,2) [SizeGB], -- Convert 8k pages to GB
Maxsize,
filename AS PhysicalFileName
FROM Master.SYS.SYSALTFILES SF
Join Master.SYS.Databases d on sf.fileid = d.database_id
Order by d.name
# Determine a Windows Login's Permission Path
This will show the user type and permission path (which windows group the user is getting its permissions from).
xp_logininfo 'DOMAIN\user'
# See if Enterprise-specific features are being used
It is sometimes useful to verify that your work on Developer edition hasn't introduced a dependency on any features restricted to Enterprise edition.
You can do this using the sys.dm_db_persisted_sku_features system view, like so:
SELECT * FROM sys.dm_db_persisted_sku_features
Against the database itself.
This will list the features being used, if any.
# Retrieve Database Options
The following query returns the database options and metadata:
select * from sys.databases WHERE name = 'MyDatabaseName';
# Show Size of All Tables in Current Database
SELECT
s.name + '.' + t.NAME AS TableName,
SUM(a.used_pages)*8 AS 'TableSizeKB' --a page in SQL Server is 8kb
FROM sys.tables t
JOIN sys.schemas s on t.schema_id = s.schema_id
LEFT JOIN sys.indexes i ON t.OBJECT_ID = i.object_id
LEFT JOIN sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id
LEFT JOIN sys.allocation_units a ON p.partition_id = a.container_id
GROUP BY
s.name, t.name
ORDER BY
--Either sort by name:
s.name + '.' + t.NAME
--Or sort largest to smallest:
--SUM(a.used_pages) desc
# Retrieve Tables Containing Known Column
This query will return all COLUMNS and their associated TABLES for a given column name. It is designed to show you what tables (unknown) contain a specified column (known)
SELECT
c.name AS ColName,
t.name AS TableName
FROM
sys.columns c
JOIN sys.tables t ON c.object_id = t.object_id
WHERE
c.name LIKE '%MyName%'
# Search and Return All Tables and Columns Containing a Specified Column Value
This script, from here (opens new window) and here (opens new window), will return all Tables and Columns where a specified value exists. This is powerful in finding out where a certain value is in a database. It can be taxing, so it is suggested that it be executed in a backup / test enviroment first.

# Remarks
As with other relational database systems, SQL Server exposes metadata about your databases.
This is provided through the ISO Standard INFORMATION_SCHEMA schema, or the SQL Server-specific sys catalog views.
