Dynamically Find out the Integer and Decimal Data Type of a Column

Question

Table: test (INTE number, DECI number(7,2))
Try to dynamically determine the column type.
Using select data_type from user_tab_columns. It only returns NUMBER which does not indicate if the column is an integer or decimal data type.
Is there a way to dynamically determine if a column is integer or decimal type?
Thanks

Answer 1

First of all your column INTE stores not just integers but any franctional numbers too:
SQL> create table test(INTE number, DECI number(7,2))
  2  /
Table created.
SQL> insert
  2    into test
  3    values(
  4           10.99,
  5           10.99
  6          )
  7  /
1 row created.
SQL> select  *
  2    from  test
  3  /
      INTE       DECI
     10.99      10.99
SQL>If you want to declare column as integer you use either NUMBER(n) or INTEGER. And, as others already pointed out, you can check DATA_PRECISION & DATA_SCALE in data dictionary view USER/ALL/DBA_TAB_COLUMNS.
