Bryan Pendleton updated DERBY-1491: ----------------------------------- Attachment: alterColumnDefault1.diff Attached is alterColumnDefault1.diff. This diff merges the db2AlterColumn() and columnAlterClause() parsing routines in sqlgrammar.jj. Although this is a more complicated diff to the parser than the first patch, I think it is preferable because this way all the column alterations come through ALTER TABLE ALTER COLUMN, rather than trying to have both ALTER COLUMN and MODIFY COLUMN. > Provide ALTER TABLE functionality to change a column's default value > -------------------------------------------------------------------- > > Key: DERBY-1491 > URL: http://issues.apache.org/jira/browse/DERBY-1491 > Project: Derby > Issue Type: New Feature > Components: Documentation, SQL > Affects Versions: 10.0.2.0, 10.0.2.1, 10.1.1.0, 10.2.0.0, 10.1.2.1, > 10.1.3.0, 10.1.3.1 > Reporter: Bryan Pendleton > Assigned To: Bryan Pendleton > Attachments: alterColumnDefault1.diff, modifyDefault_1.diff > > > Provide a way to alter the default value for an existing column in an > existing table.
