The Oracle INSERT ALL statement is used to insert multiple rows with a single INSERT statement. You can insert the rows into one table or multiple tables by using only one SQL command

Syntax

INSERT ALL  
  INTO table_name (column1, column2, column_n) VALUES (expr1, expr2, expr_n)  
  INTO table_name(column1, column2, column_n) VALUES (expr1, expr2, expr_n)  
  INTO table_name (column1, column2, column_n) VALUES (expr1, expr2, expr_n)  
SELECT * FROM dual;  

Parameters

1- table_name: it specifies the table in which you want to insert your records

2- column1, column2, column_n: this specifies the columns in the table to insert values

3- expr1, expr2, expr_n: this specifies the values to assign to the columns in the table.

Oracle INSERT ALL Example

This example specifies how to insert multiple records in one table. Here we insert three rows into the "suppliers" table

INSERT ALL  
  INTO suppliers (supplier_id, supplier_name) VALUES (20, 'Google')  
  INTO suppliers (supplier_id, supplier_name) VALUES (21, 'Microsoft')  
  INTO suppliers (supplier_id, supplier_name) VALUES (22, 'Apple')  
SELECT * FROM dual;  

Output

3 row(s) inserted.
0.02 seconds

This is totally equivalent to the following three INSERT statements

INSERT INTO suppliers (supplier_id, supplier_name) VALUES (1000, 'Google');  
INSERT INTO suppliers (supplier_id, supplier_name) VALUES (2000, 'Microsoft');  
INSERT INTO suppliers (supplier_id, supplier_name) VALUES (3000, 'Apple');  

Oracle INSERT ALL Example: (Insert into multiple tables)

The INSERT ALL statement can also be used to insert multiple rows into more than one table by one command only

In the following example, we are going to insert records into the both "suppliers" and "customers" tables

INSERT ALL  
  INTO suppliers (supplier_id, supplier_name) VALUES (30, 'Google')  
  INTO suppliers (supplier_id, supplier_name) VALUES (31, 'Microsoft')  
  INTO customers (age, name, address) VALUES (29, 'Luca Warsi', 'New York')  
SELECT * FROM dual;  

Output

3 row(s) inserted.
0.03 seconds

Here, total 3 rows are inserted, 2 rows are inserted into the suppliers table and one row into the customers table
