Additional constraints

Besides these naming conventions and data types, when you map LN data to Oracle data, these rules apply:

• All names the database driver generates are in lowercase characters and are not enclosed in double quotes; therefore, when storing the names in the Oracle dictionary, Oracle converts these names to uppercase. When Oracle retrieves names from the Oracle dictionary, the names display in uppercase.
• All columns that the LN Oracle driver creates have the NOT NULL constraint. LN applications do not support NULLS.
