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 CHAR, BYTE, CHARACTER CHARACTER SET GRAPHIC, VARCHAR CHARACTER SET GRAPHIC, VARCHAR, VARBYTE or NUMBER data type, the table function can use getLength() to get the length of the data type.

Argument

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

Exceptions

If the index argument specifies an array element that is not a CHAR, BYTE, CHARACTER CHARACTER SET GRAPHIC, VARCHAR CHARACTER SET GRAPHIC, VARCHAR, VARBYTE or NUMBER column, getLength() throws an SQLException to indicate that Tbl.getLength(int) is invalid for the type of column intended, setting the SQLException fields as follows.
