What is the use of SELECT and INSERT command?

Question

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 match. Note: The existing records in the target table are unaffected.

What is the use of insert command?

The insert command is used for inserting one or more rows into a database table with specified table column values. The first DML command executed immediately after a table creation is the insert statement.

What is the use of select command?

The SELECT command creates a temporary select-list of file items to be processed by the next TCL or INFO/ACCESS statement, or by other processors such as the Editor, mvBASIC, or PROC. Creating a select-list is a useful way to define and operate on a subset of items in a database.

Can we use select in insert statement?

You can use a select-statement within an INSERT statement to insert zero, one, or more rows into a table from the result table of the select-statement. The select-statement embedded in the INSERT statement is no different from the select-statement you use to retrieve data.

What is the difference between select into and insert into?

INSERT INTO SELECT inserts into an existing table. SELECT INTO creates a new table and puts the data in it.
