Table types for

You can create logging or nonlogging tables in a logging database on HCL OneDB™. The two table types are STANDARD (logging tables) and RAW (nonlogging tables). The default standard table is like a table created in earlier versions without a special keyword specified. You can create either a STANDARD or RAW table and change tables from one type to another.

In a nonlogging database, both STANDARD tables and RAW tables are nonlogging. In a nonlogging database, the only difference between STANDARD and RAW tables is that RAW tables do not support primary-key constraints, unique constraints, referential constraints, or rollback. However, these tables can be indexed and updated.

The following table lists the properties of the types of tables available with HCL OneDB. The flag values are the hexadecimal values for each table type in the flags column of systables.
