In Database replace null with 0

Hi,

I have a dataset via in-DB tool which includes null values that i would like to replace with 0. I'll be making calculations on the columns using the formula in-db tool, but it currently doesn't read these null values so the output remains null.

I understand we can use the data cleanse tool, but i'll need to data stream out in order to do this and the second part of the workflow involves the calculations so i'm not sure how i'd get the data back in.

Does anyone know what is the best way to go about this?

Thanks

If you use Formula In-DB with SQL Server, this will work.

ISNULL([Field], 0)

If it's Oracle:

NVL([Field], 0)

If it's MySQL

IFNULL([Field], 0)

Cheers,

Hi @Thableaus

I'm using SQL Server.

Will I need to input the formula for all fields affected? The multi-field formula tool is quite handy as I could convert multiple fields at the same time.

Thanks
