Description
A constraint is used to define rules that help to provide data integrity. Column constraints are specific to the column name specified. You must have ALTER privilege on the table. The table will be locked for EXCLUSIVE use during the operation.
The NOCPTRANS column constraint is used to prevent code page translation for character and memo fields.
Example
ALTER TABLE customer; ALTER COLUMN notes NOCPTRANS
