There is a difference in behavior between SQLDescribeParam and SQLGetDescRec.
SQLDescribeParam returns valid data whereas SQLGetDescRec for an IPD returns unreasonable, perhaps default, data, both called after SQLPrepare with a statement like "insert into tab1 values (?, ?, ?)".

MS states in the docu:

SQLDescribeParam returns the description of a parameter marker associated
with a prepared SQL statement. This information is also available in the
fields of the IPD.
