Method Summary

Modifier and Type	Method	Description

Method Details

renameLivingColumn

void renameLivingColumn(SchemaNode aNode,
 String columnNewName)
                 throws OperationException

Renames an active column of a table.

If the table exists in several mapped modes (history, replication, relational), the change will affect all of them.

Parameters:

aNode - the data model node for the element to be renamed

columnNewName - the target name for the column

Throws:

OperationException - if the new name cannot be assigned because of database constraints.

5.9.0

renameDisabledColumn

void renameDisabledColumn(SchemaNode aNode,
 String columnNewName,
 String columnOldNameOrNull)
                   throws OperationException

Renames a disabled column of a table.

If the table exists in several mapped modes (history, replication, relational), the change will affect all of them.

Parameters:

aNode - the data model node for the element to be renamed

columnNewName - the target name for the column

columnOldNameOrNull - This parameter can be passed as null in most cases. If a non-null parameter value is provided, it has to match the existing name for this column; this extra verification makes non-ambiguous the choice of the column to be renamed; indeed, if the element has undergone several type evolutions, it might be represented in the database by several columns with distinct names.

Throws:

OperationException - if the specified parameters do not map to exactly one database column, or if the new name cannot be assigned because of database constraints.

5.9.0
