SQL INSERT INTO SELECT Statement
The SQL INSERT INTO SELECT Statement
The INSERT INTO SELECT statement copies data from one table and inserts it into another table.
The INSERT INTO SELECT statement requires that the data types in source and target tables matches.
Note: The existing records in the target table are unaffected.
INSERT INTO SELECT Syntax
Copy all columns from one table to another table:
SELECT * FROM table1
WHERE condition;
Copy only some columns from one table into another table:
SELECT column1, column2, column3, ...
FROM table1
WHERE condition;
