Setting null data options

Beginning with version 5.3, the M-Business XML conduit supports null values for data elements. In earlier versions, numeric data elements could have a value of zero and string data elements could have a value of spaces, but they could not be null.

Note

You can specify that null values are allowed on not at the column level. If a column is specified as required, it cannot have a null value. In attribute-based schemas, null values are allowed by default; in element-based schemas, null values are disallowed by default.

Caution

If you are supporting users with M-Business Client version 5.2, be sure that you set up your database fields to disable support for null values; M-Business Client version 5.2 will not display nulls correctly.
