How to Remove Leading Zeros from Alphanumeric Text Fields in MySQL?

Trimming Leading Zeros in Alphanumeric Text in MySQL Functions

If you're working with alphanumeric text fields in MySQL and need to remove leading zeros, the trim() function is a reliable option.

The trim() function allows you to specify a set of characters to be trimmed from the beginning or end of a string. To trim leading zeros, you would use the following syntax:

TRIM(LEADING '0' FROM <field_name>)

Here's an example:

SELECT TRIM(LEADING '0' FROM myfield) FROM table;

If the myfield column contains the value "00345ABC," the query will return "345ABC." This is because the trim() function will remove all leading zeros from the field, leaving you with the desired result.

Note that if the field contains non-numeric characters alongside the zeros, the trim() function will only remove the numerical zeros. This means that if the field contains the value "00ABC345," the trim() function will return "ABC345."
