).

Note:
Do not create tables with LONG
columns. Use LOB columns (CLOB
, NCLOB
) instead. LONG
columns are supported only for backward compatibility.
Oracle also recommends that you convert existing
LONG
columns to LOB columns. LOB columns are subject to far fewer restrictions than LONG
columns. Further, LOB functionality is enhanced in every release, whereas LONG
functionality has been static for several releases.
Columns defined as
LONG
can store variable-length character data containing up to 2 gigabytes of information. LONG
data is text data that is to be appropriately converted when moving among different systems.LONG
datatype columns are used in the data dictionary to store the text of view definitions. You can use LONG
columns in SELECT
lists, SET
clauses of UPDATE
statements, and VALUES
clauses of INSERT
statements.
