How Can I Correctly Cast a VARCHAR Field to an INT in MySQL?

Correctly Casting VARCHAR to INT in MySQL

MySQL queries involving VARCHAR to INT conversion often result in syntax errors due to improper casting techniques. This guide demonstrates the correct method using CAST functions.

The acceptable result types for casting are limited. Specifically, you should use UNSIGNED [INTEGER] as the target data type.

The accurate syntax for this conversion is:

<code class="language-sql">SELECT CAST(PROD_CODE AS UNSIGNED) FROM PRODUCT;</code>

This query will successfully cast the PROD_CODE VARCHAR field to an unsigned integer.
