ntext, text, and image
Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.
Variable-length Unicode data with a maximum length of 230 - 1 (1,073,741,823) characters. Storage size, in bytes, is two times the number of characters entered. The SQL-92 synonym for ntext is national text.
Variable-length non-Unicode data in the code page of the server and with a maximum length of 231-1 (2,147,483,647) characters. When the server code page uses double-byte characters, the storage is still 2,147,483,647 bytes. Depending on the character string, the storage size may be less than 2,147,483,647 bytes.
Variable-length binary data from 0 through 231-1 (2,147,483,647) bytes.
These functions and statements can be used with ntext, text, or image data.
