    Description

      Oracle Number : Precision and scale

      Oracle allows the scale to be negative.

      If you specify a negative scale, Oracle Database rounds the actual data to the specified number of places to the left of the decimal point. For example, specifying (7,-2) means Oracle Database rounds to the nearest hundredths

      The `java.math.BigDecimal` scale must be between 0 and the precision 18 (both inclusive).

      It gives the following exception:

      cause: org.apache.kafka.connect.errors.DataException: BigDecimal has mismatching scale value for given Decimal schema
