I have a column which has decimal value of 18,8. I was asked to extend it to 18,18 to hold more places after ,.
ALTER TABLE [dbo].[TransakcjeGotowkowe]
ALTER COLUMN TransakcjeGotowkoweKwota decimal (18,18) NULL
Msg 8115, Level 16, State 8, Line 1
Arithmetic overflow error converting numeric to data type numeric.
The statement has been terminated.
I have also tried to do it by GUI. Nothing else changes just want to hold more data after ,.
