How to Correctly Insert Extracted Data into a New Table in MS Access?

Moving Data Between MS Access Tables: A Guide

In MS Access databases, you'll often need to move data from one table to another, often after some transformation. The INSERT INTO statement is key, but incorrect syntax can lead to errors.

Troubleshooting Syntax Errors

A common mistake when using INSERT INTO with a subquery is including extra elements. The VALUES keyword and parentheses around the subquery are unnecessary in this context.

Correct Syntax for Data Insertion

Here's the correct approach:

<code class="language-sql">INSERT INTO Table2 (LongIntColumn2, CurrencyColumn2)
SELECT LongIntColumn1, Avg(CurrencyColumn) AS CurrencyColumn1
FROM Table1
GROUP BY LongIntColumn1;</code>

This streamlined query efficiently extracts data from Table1, groups it by LongIntColumn1, computes the average of CurrencyColumn, and inserts the results into Table2's LongIntColumn2 and CurrencyColumn2 fields. This eliminates syntax errors and ensures data integrity.
