Accessing a Row Type

When a row type (named or unnamed) is used as a column of a table, its fields can be accessed in exactly the same ways that the columns of a row are accessed. That is, you create a series of nested loops that use the following functions:

• The mi_next_row( ) function controls a loop that iterates through each retrieved row type.
• The mi_value( ) or mi_value_by_name( ) function controls a loop that iterates through each field value.

For more information on how to use these functions, see Obtaining Row Values.
