SELECT...INTO Statement

SELECT...INTO Statement

Creates a make-table query.

Syntax

SELECT field1[, field2[, ...]] INTO newtable [IN externaldatabase]
FROM source

The SELECT...INTO statement has these parts:

Part

Description

field1, field2

The name of the fields to be copied into the new table.

newtable

The name of the table to be created. If newtable is the same as the name of an existing table, a trappable error occurs.

externaldatabase

The path to an external database. For a description of the path, see the IN clause.

source

The name of the existing table from which records are selected. This can be single or multiple tables or a query.


Remarks

You can use make-table queries to archive records, make backup copies of your tables, or make copies to export to another database or to use as a basis for reports that display data for a particular time period. For example, you could produce a Monthly Sales by Region report by running the same make-table query each month.

Note: 

  • You may want to define a primary key for the new table. When you create the table, the fields in the new table inherit the data type and field size of each field in the query's underlying tables, but no other field or table properties are transferred.

  • To add data to an existing table, use the INSERT INTO statement instead to create an append query.

  • To find out which records will be selected before you run the make-table query, first examine the results of a SELECT statement that uses the same selection criteria.
