I have an address column in a table which is of varchar() type so that it can contain alphanumeric data.

I need to fetch a row which contains only numeric data.

Could you please help me out?


What format is the numeric data in, packed, binary, or character?

It is a number like 123456.......
it resides in a column which is varchar() type.
Now number can start with any digit.

Also i have to fetch the row that contains only number no character or specail character.

Hello,

Sounds like this is not really an address. If it is not, it should not be stored in an "address" column, but rather in some other properly defined column(s).

What should happen if the data is "12 34 56"? Is there a maximum or minimum "valid" length? Does the query need to traverse the entire table or is there some additonal selection criteria?
