The problem is you are trying to insert the decimal value 40,7 in Oracle table however the database doesn’t consider this as a valid input string most likely because you are using comma as the decimal separator and your database might be set to use different character such as a dot (.)

You can query the SYS table NLS_DATABASE_PARAMETERS to find out the localization setting used in your DB. The following SQL statement tells you what is the decimal separator setting used.


The value for the Paremeter NLS_NUMERIC_CHARACTERS contains 2 characters. First one is the decimal separator and second is the group separator. For example if the Parameter value is ., it means that decimal separator is . and group separator is ,

Example: 12,345,23.08


To change the decimal separator character run the SQL statement


The above statement will set decimal separator as comma (,) and group separator as space. 

example: 12 345 23,08
