Question

Hi can anyone help with a quire to retrieve both numeric and alpha numeric entries from a column.

Example: Column is 'ID' and entries could be = abc0000 or could be all 9999999999.

The search is a list of numeric and alphanumeric items.

Example: 8765398 ha34789 ss0487667 7629

Answer 1

You could do:

SELECT * FROM table WHERE ID REGEXP '^[A-Za-z0-9]+$'

You could also use a named character :

SELECT * FROM table WHERE ID REGEXP '^[[:alnum:]]+$'
