Question

A very easy one for someone, The following insert is giving me the

ORA-01722: invalid number

why?

INSERT INTO C         


        

Answer 1

An ORA-01722 error occurs when an attempt is made to convert a character string into a number, and the string cannot be converted into a number.

Without seeing your table definition, it looks like you're trying to convert the numeric sequence at the end of your values list to a number, and the spaces that delimit it are throwing this error. But based on the information you've given us, it could be happening on any field (other than the first one).
