Subject [jira] Created: (DERBY-1515) Provide ALTER TABLE functionality to change a column's data type
Date Sun, 16 Jul 2006 16:27:13 GMT
Provide ALTER TABLE functionality to change a column's data type
----------------------------------------------------------------

                 Key: DERBY-1515
                 URL: http://issues.apache.org/jira/browse/DERBY-1515
             Project: Derby
          Issue Type: New Feature
          Components: Documentation, SQL
    Affects Versions: 10.1.3.1, 10.1.2.1, 10.1.1.0, 10.2.0.0
            Reporter: Bryan Pendleton
            Priority: Minor


Derby should provide a feature which allows a user to change the data type of an existing
column in an existing table.

Currently, there exists the statement:

    ALTER TABLE tablename ALTER COLUMN columnname SET DATA TYPE datatype

However, this statement currently only allows increasing the length of a VARCHAR column. You
are not allowed to decrease the width or to change the data type.

It would be nice if this restriction could be lifted, and the datatype could be changed.
