This article provides the script to find all the Tables with or without an Identity column
Tables with Identity column
We can write a query like below to get all the Tables with Identity column:
SELECT name 'Table with Identity column'
FROM SYS.Tables
WHERE OBJECTPROPERTY(object_id,'TableHasIdentity') = 1
AND type = 'U'
Tables without Identity column
We can write a query like below to get all the Tables without Identity column:
SELECT name 'Table without Identity column'
FROM SYS.Tables
WHERE OBJECTPROPERTY(object_id,'TableHasIdentity') = 0
AND type = 'U'
EXAMPLE
Let us understand the above scripts with an example. To understand this, let us create a demo database SqlHintsDemoDB with Customers table having an identity column and an Orders table without identity column.
CREATE DATABASE SqlHintsDemoDB
GO
USE SqlHintsDemoDB
GO
/*Let us create Customers table with Identity column.*/
CREATE TABLE dbo.Customers (
CustomerId int IDENTITY (1, 1)
PRIMARY KEY CLUSTERED NOT NULL ,
FirstName Varchar(50),
LastName Varchar(50))
GO
/*Let us create Orders Table without and Identity column.*/
CREATE TABLE dbo.Orders (
OrderId int NOT NULL ,
CustomerId int NOT NULL ,
CreationDT DATETIME NOT NULL)
GO
Now let us run the queries to get the list of all Tables with or without identity column and verify the result:
