INSERT INTO

1 min read

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

Two Ways

  1. Specify both the column names and the values to be inserted:
INSERT INTO table_name (column1, column2, column3, ...)  
VALUES (value1, value2, value3, ...);
  1. If you are adding values for all the columns of the table, you do not need to specify the column names in the SQL query. However, make sure the order of the values is in the same order as the columns in the table. Here, the INSERT INTO syntax would be as follows:
INSERT INTO table_name  
VALUES (value1, value2, value3, ...);

Example

INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)  
VALUES ('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway');

Insert Data Only in Specified Columns

INSERT INTO Customers (CustomerName, City, Country)  
VALUES ('Cardinal', 'Stavanger', 'Norway');

Insert Multiple Rows

INSERT INTO Customers (CustomerName, ContactName, Address, City, PostalCode, Country)  
VALUES  
('Cardinal', 'Tom B. Erichsen', 'Skagen 21', 'Stavanger', '4006', 'Norway'),  
('Greasy Burger', 'Per Olsen', 'Gateveien 15', 'Sandnes', '4306', 'Norway'),  
('Tasty Tee', 'Finn Egan', 'Streetroad 19B', 'Liverpool', 'L1 0AA', 'UK');
