How can filtering be done conditionally in MYSQL based on the first two characters?

edit

To filter data conditionally based on the first two characters in MySQL, you can use the LEFT() function to extract the first two characters and then use the WHERE clause to filter the results.

For example:

SELECT * FROM tablename WHERE LEFT(columnname,2) = 'AB';

This will return all rows where the first two characters of the column_name are 'AB'. You can replace 'AB' with any other combination of characters as per your requirement.
