getPrecision(int index) - Advanced SQL Engine - Teradata Database

If a table function with dynamic result row specification calls Tbl.getColDef(), and the value of an element in the resulting array corresponds to a TIME, TIMESTAMP, DECIMAL or NUMBER data type, the table function can use getPrecision() to get the precision of the data type.

Argument

The index argument specifies which element in the array returned by Tbl.getColDef() to get the precision of.

Exceptions

If the index argument specifies an array element that is not a TIME, TIMESTAMP, DECIMAL or NUMBER column, getPrecision() throws an SQLException to indicate that Tbl.getPrecision(int) is invalid for the type of column intended, setting the SQLException fields as follows.
