---------------------------------------------------------------
If you execute `{{create table test (a decimal(1,3));`}} in *MySQL*, will occur
error:
{{Schema Error: Error: ER_M_BIGGER_THAN_D: For float(M,D), double(M,D) or
decimal(M,D), M must be >= D (column 'a').}}
Also in *Spark/hive*:
{{scala> spark.sql("CREATE TABLE foo (a DECIMAL(5, 7))").collect}}
org.apache.spark.sql.catalyst.parser.ParseException: Decimal scale (7) cannot
be greater than precision (5).
hive> CREATE TABLE foo (a DECIMAL(5, 7));
2020-09-22 14:38:55,062 FAILED: IllegalArgumentException Decimal scale must be
less than or equal to precision
