Insert Data Into The Table SQL SERVER

 First we have to create table with the table name Student with the following fields in which we are going to insert records.

Column Name	Data Type	Length
Std_Name	Varchar	50
Address	Varchar	50
City	Varchar	50
Age	Numeric	8
DOB	DateTime	8
Class	Varchar	10

Insert Data Into The Table for execution of queries open the new query window from the Microsoft Sql Server Management Studio.

Select SQL Server from the drop down combo if you are using the client else in case of server enter (local) like above. Select window authentication or SQL Server authentication according to your system installation and click on OK. Query window will appear as you click on New Query marked as first red. Select your database from the combo displaying at the toolbar above on the screen. Now write down the following query in the displaying window.

·          The syntax for insertion is –

Insert into table name values (‘String value’, numeric value)

Use single quotes for passing the character value and numeric value will be passed with out quotes. Date time will be passed with single quotes using “MM/DD/YYYY” format.

·          For passing the data in all fields of the above table

Insert into student values (‘Ram’,’Saheed Nagar’, ‘AGRA’, 21, ‘12/25/1987’, ‘10’)

·          For passing the data in specified fields of the above table

Insert into student (std_name, Address, city, age) values (‘Ram’,’Saheed Nagar’, ‘AGRA’, 21)

·          For passing the complete table in another table with same data structure.

Insert into second Table Name select * from first Table Name

·          For passing the complete table in another table with different data structure.

Insert into second Table Name select field1, field2, field3 from first Table Name

·          INSERT with DEFAULT VALUES

INSERT student DEFAULT VALUES

                INSERT employee VALUES ('KLT91469F', 'Katrina', 'L', 'Thompson', DEFAULT, DEFAULT, DEFAULT, '01/14/95')

When inserting rows, these rules apply:

·          Inserting an empty string (' ') into a varchar or text column inserts a single space. All char columns are right-padded to the    defined length. All trailing spaces are removed from data inserted into varchar columns, except in strings that contain only spaces. These strings are truncated to a single space.

·          If an INSERT statement violates a constraint, default, or rule, or if    it is the wrong datatype, the statement fails and SQL Server displays    an error message. Constraints are defined with either the CREATE TABLE    or ALTER TABLE statement. Defaults are created with the CREATE DEFAULT statement and rules are created with the CREATE RULE statement.

·          Inserting a null value into a text or image column does not create a    valid text pointer, nor does it pre-allocate a 2K text page. For details    on inserting text and image data, see the text and image Manipulation    topic.

·           An INSERT statement must follow the rules for a batch. For details, see the Batches topic.

When you specify values for only some of the columns in the column list, one of three things can happen to the columns that have no values:

·          A default value is entered if the column has a DEFAULT constraint, if a default is bound to the column, or a default is bound to the underlying user-defined datatype.

·          NULL is entered if the column allows NULLs and no default value exists for the column.

·          An error message is displayed and the row is rejected if the column    is defined as NOT NULL and no default exists.
