How do I check to see if a value is an integer in MySQL?

I have been been trying to select only the numeric rows from a field in mysql.

A sample of the data in the database would be:

‘1234543’
’12f4231′
‘fdfrgr34’
etc.

I want my select statement to only return the numeric rows.

So in this case the only row I would get back would be the ‘1234543’ row.

Any help would be greatly appreciated.

Thanks,
Stefan.

Try this

SELECT * FROM table_name WHERE column_name REGEXP '^[0-9]+$';
