SQL Insert Statement 10

SQL INSERT Statement

by

The SQL INSERT statement adds new records into tables or to insert data into SQL tables. The syntax of the INSERT statement in SQL Server is

-- SQL Server INSERT Syntax
INSERT INTO [Destination Table] ([Column1], [Column2],..., [ColumnN])
VALUES ([Column1_Value], [Column2_Value],..., [ColumnN_Value])
  • Destination Table: Fully qualifies Table name to insert records
  • Column1…..ColumnN: Choose the number of columns from the tables.
  • Column1_Value…..ColumnN_Value: Values that you want to insert. For example, Column1_Value inserted for Column1. If you omit the field names, you must specify the column_values (field values) in the order defined by the destination table structure

We can write this Sql Server Insert Statement as,

-- SQL Server INSERT Syntax
INSERT INTO [Destination Table]
VALUES ([Column1_Value], [Column2_Value],..., [ColumnN_Value])

This table holds two records, and we will perform the insert operations on it.

SQL Insert Statement 1

SQL INSERT Statement Example

This Insert Statement example insert a new record into [SQL Insert] Table in a more traditional way. Here, we haven’t inserted the ID value because it is an identity column, and it will be updated automatically

-- SQL Server Insert Example
USE [SQL Tutorial]
GO

INSERT INTO [dbo].[SQL Insert] (
	[FirstName], [LastName], [Occupation], [YearlyIncome], [Sales])
VALUES ('Tutorial', 'Gateway', 'Education', 10000, 200)
SQL Insert Statement 2

If we are inserting data for all the Columns, then we can ignore the column names of the destination table (Syntax 2). It means the above SQL Server Insert Statement can also write as:

-- SQL Insert Statement Example
INSERT INTO [dbo].[SQL Insert] 
VALUES ('SQL', 'Programming', 'Database', 50000, 1800)

TIP: It is not good practice to ignore the column names. So, always provide the column names in SQL Server.

Above T-SQL query will insert data into [FirstName], [LastName], [Occupation], [YearlyIncome], and [Sales] columns. Whenever you omit the field names, you must specify the column_values (field values) in the order defined by the destination table structure. It means SQL value will be inserted in [FirstName] column etc.

-- SQL Server Insert Statement Example
INSERT INTO [dbo].[SQL Insert] 
	SELECT [FirstName], [LastName], [Occupation], [YearlyIncome], [Sales]
	FROM [SQL Tutorial].[dbo].[Employ]
	WHERE ID > 2

Above query insert [FirstName], [LastName], [Occupation], [YearlyIncome], and [Sales] columns from the source table where [ID] value is greater than 2 into the [SQL Insert] table.
