unitext Datatype

The variable-length unitext datatype can hold up to 1,073,741,823 Unicode characters (2,147,483,646 bytes). You can use unitext anywhere you use the text datatype, with the same semantics. unitext columns are stored in UTF-16 encoding, regardless of the SAP ASE default character set.

The unitext datatype uses the same storage mechanism as text. To save storage space, define unitext columns as NULL. When you initialize a unitext column with a non-null insert or update clause, SAP ASE assigns a text pointer and allocates an entire 2K data page to hold the value.
