COPY TABLE copies the table into a new table. Make sure that the name of

the target file does not already exist. The name stored internally will be

modified accordingly. It is possible to specify logical table names.

COPY TABLE TOOL TO 'OEM:\TOOL.T'

COPY TABLE 'OEM:\TOOL.T' TO 'OEM:\TOOL2.T'

DROP TABLE deletes an existing table file. If a logical table name is specified,

the file identified by the name will be deleted.

DROP TABLE TOOL

DROP TABLE 'OEM:\TOOL.T'

RENAME COLUMN changes the name of an existing column. The properties

of the column are not changed. If the configuration of the table is stored locally

in the table, the name of the column is also changed in the respective

configuration data.

'(' column-list ')'
