You can use a null value/function information file to store the null value in a table when a specified comparison value matches the input data. Specify this operand if the name of the constructor function that generates the values to be stored in a column of abstract data type differs from the name of the data type of the column, or if you want to specify information about multiple functions.

A statement specified in this null value/function information file is called a column number statement.

A null value/function information file is applicable only to an input data file in the binary format.

Be sure to specify a column number statement in one line. To specify information for multiple columns, specify as many column number statements as there are columns.
