ODBC index-name grammar is supported on a per workstation basis for the following:
CREATE INDEX DROP INDEX DROP TABLE SQLStatistics()
CREATE INDEX myindex ON mytable (column1, column2)
ODBC grammar ASC and DESC column-identifier clauses for CREATE INDEX are ignored since Teradata does not support this type of indexing. It is possible to DROP an index using the index-name which was specified when it was created, provided you are working on the same PC and the IndexName entry in the Registry file has not been reused.
The specified index-name need not exist on the PC; it is not relevant to Teradata because an index is created for the specified table using the standard index grammar.
CREATE INDEX (columnname(s)) ON tablename
If the named index has been deleted from the Registry, or if a user is on a different PC, the index needs to be DROPped using the Teradata grammar by specifying the tablename and columns that make up the index. For example,
DROP INDEX (columnname(s)) ON tablename
You cannot DROP a Teradata named index (for example, TableName004).
