How to Find Tables With Primary and Foreign Key Constraint in Database

Table with ForiegnKey constraint

USE EDW; --Database name
GO
SELECT f.name AS ForeignKey,
OBJECT_NAME(f.parent_object_id) AS TableName,
COL_NAME(fc.parent_object_id,
fc.parent_column_id) AS ColumnName,
OBJECT_NAME (f.referenced_object_id) AS ReferenceTableName,
COL_NAME(fc.referenced_object_id,
fc.referenced_column_id) AS ReferenceColumnName
FROM sys.foreign_keys AS f
INNER JOIN sys.foreign_key_columns AS fc
ON f.OBJECT_ID = fc.constraint_object_id

Table with PrimaryKey constraint


USE EDW;  --Database name
GO
SELECT i.name AS IndexName,
OBJECT_NAME(ic.OBJECT_ID) AS TableName,
COL_NAME(ic.OBJECT_ID,ic.column_id) AS ColumnName
FROM sys.indexes AS i
INNER JOIN sys.index_columns AS ic
ON i.OBJECT_ID = ic.OBJECT_ID
AND i.index_id = ic.index_id
WHERE i.is_primary_key = 1

Find a table in a database

Below is the code to find a table in a database

USE XXXX  --Database name

SELECT * FROM sys.Tables
WHERE name LIKE '%Address%'

Below is the code to find a table in all database with stored procedure


USE Master
GO
CREATE PROCEDURE usp_FindTableNameInAllDatabase
@TableName VARCHAR(256)
AS
DECLARE @DBName VARCHAR(256)
DECLARE @varSQL VARCHAR(512)
DECLARE @getDBName CURSOR
SET @getDBName = CURSOR FOR
SELECT name
FROM sys.databases
CREATE TABLE #TmpTable (DBName VARCHAR(256),
SchemaName VARCHAR(256),
TableName VARCHAR(256))
OPEN @getDBName
FETCH NEXT
FROM @getDBName INTO @DBName
WHILE @@FETCH_STATUS = 0
BEGIN
SET @varSQL = 'USE ' + @DBName + ';
INSERT INTO #TmpTable
SELECT '''+ @DBName + ''' AS DBName,
SCHEMA_NAME(schema_id) AS SchemaName,
name AS TableName
FROM sys.tables
WHERE name LIKE ''%' + @TableName + '%'''
EXEC (@varSQL)
FETCH NEXT
FROM @getDBName INTO @DBName
END
CLOSE @getDBName
DEALLOCATE @getDBName
SELECT *
FROM #TmpTable
DROP TABLE #TmpTable

To run the above store proc:
EXEC usp_FindTableNameInAllDatabase 'xxxTablenamexxx'    --Table name

If Exists Logic

If exists logic for a Database

IF EXISTS(select * from sys.databases where name='yourDBname')

If exists logic for a table

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[DimPACodes]') AND type in (N'U'))

If exists logic for a synonms

IF  EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N's_DimPACodes') AND type in (N'SN'))

If exists logic for a View

IF  EXISTS (SELECT * FROM sys.views WHERE object_id = OBJECT_ID(N'vw_DimProgram') AND type in (N'V'))

If exists logic for a column

IF NOT EXISTS (SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'Dimprogram' and COLUMN_NAME = 'IAPKey')

If exists logic for a Schema

IF NOT EXISTS(SELECT * FROM sys.schemas where name = N'Test')

EXEC ('CREATE SCHEMA [telligent] Authorization [dbo]')

GO

(OR)

IF NOT EXISTS(SELECT * FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_SCHEMA = 'Test')

EXEC ('CREATE SCHEMA [Test] Authorization [dbo]')

GO

IF = SQL inline table-valued function
IT = Internal table
P  = SQL Stored Procedure
PC = Assembly (CLR) stored-procedure
PG = Plan guide
PK = PRIMARY KEY constraint
