Constructor Details

RenameConstantAction

public RenameConstantAction(String fullTableName,
 String tableName,
 String oldObjectName,
 String newObjectName,
 SchemaDescriptor sd,
 UUID tableId,
 boolean usedAlterTable,
 int renamingWhat)

Make the ConstantAction for a RENAME TABLE/COLUMN/INDEX statement.

Parameters:

fullTableName - Fully qualified table name

tableName - Table name.

oldObjectName - This is either the name of column/index in case of rename column/index. For rename table, this is null.

newObjectName - This is new name for table/column/index

sd - Schema that table lives in.

tableId - UUID for table

usedAlterTable - True-Used Alter Table, False-Used Rename. For rename index, this will always be false because there is no alter table command to rename index

renamingWhat - Rename a 1 - table, 2 - column, 3 - index

Method Details

toString
