Separator for floating point numbers

Question

Hello,
I work with oracle 9 and have a problem with the entry of floating point numbers.
The separator for floating point numbers in my data is a point (5.60).
The pre-setting of oracle is a comma (5,60).
By inserting I get the error message:
01722. 00000 - "invalid number"
How can i change this setting
Thanks for Help

Hi,
I'm not sure if I understood your problem, however the NLS_NUMERIC_CHARACTERS variable specifies the characters to use as the group separator and decimal character.
