How to interpret a value as Null from Database?

Hi,

Using NullInterpret, we can interpret any value as a null value. Example, '+' can be interpreted as a null value using the NullInterpret variable. But by definition of Nullinterpret,

"The defined symbol will when it occurs in a text file or an inline statement be interpreted as NULL."

So, if I want to interpret something ('+') from the database, how can we do that? is there any variable similar to Nullinterpret or we need to handle that logically using If statement?

Thanks

There is a function to check if a value is a number, IsNum. You can use that:

LOAD Year,

      If (IsNum(Amount), Amount, Null ()) as Amount,

xxx

Try this Karthick Sudalaiyandi:

On load the script do

If(FindOneOf(Amount,'+-><') > 0 , 'NULL',Amount) AS Amount

In the red part put the possible characters that will be considered null.
