Insert into

The INSERT INTO statement is used to insert new records/row/tuple in a table.

Syntax :-
INSERT INTO table_name (column1, column2, column3, column4,.....)
VALUES (value1, 'value2', 'value3', value4.....);

Ex :-
INSERT INTO my_tab (stu_id, name, address, mobile_no)
VALUES (05, 'Anu', 'Delhi', 982112);

Rules :-
Column and Value order should be same.
Any value that goes into a VARCHAR, CHAR, DATE, or TEXT column has single quotes around it. There are no need of quotes for numeric values (INT, DEC).

Example :-

Without specifying column name

Syntax :-
INSERT INTO table_name
VALUES(value1, 'value2', 'value3', value4);

Ex :-
INSERT INTO my_tab
VALUES (05, 'Anu', 'Delhi', 982112);

Rules :-
The values order should be same as column
We need to insert record for each column we can not leave any column.

Changing the order of column

Syntax :-
INSERT INTO table_name (column2, column1, column4, column3)
VALUES ('value2', value1, value4, 'value3');

Ex :-
INSERT INTO my_tab(name, stu_id, mobile_no, address)
VALUES ('Anu', 05, 982112, 'Delhi');

Insert Data only in Specified Columns

Syntax :-
INSERT INTO table_name (column1, column2, column3)
VALUES (value1, 'value2', 'value3')

Ex :-
INSERT INTO my_tab(stu_id, name, address)
VALUES (05, 'Anu', 'Delhi');

Insert multiple records at one time

Syntax :-
INSERT INTO table_name (column1, column2, column3, column4)
VALUES (value1, 'value2', 'value3', value4);
(value1, 'value2', 'value3', value4);

Ex :-
INSERT INTO my_tab (stu_id, name, address, mobile_no)
VALUES (01, 'Anu', 'Delhi', 982112),
(02, 'Rohan', 'Mumbai', 561425);
