Use the TRUNCATE TEXT INDEX statement when you want to delete data from a manual text index without dropping the text index
definition. For example, to alter the text configuration object for the text index to change the stoplist, truncate the text
index, change the text configuration object it refers to, and then refresh the text index to populate it with new data.
You cannot perform a TRUNCATE TEXT INDEX statement on a text index defined as IMMEDIATE REFRESH (the default). For IMMEDIATE
REFRESH text indexes, you must drop the index instead.
The TRUNCATE TEXT INDEX requires exclusive access to the table. Any open cursors that reference the table being truncated
must be closed, and a COMMIT or ROLLBACK statement must be executed to release the reference to the table.
The first statement creates the txt_index_manual text index. The second statement populates the text index with data. The
third statement truncates the text index data.
CREATE TEXT INDEX txt_index_manual ON GROUPO.MarketingInformation ( Description )
REFRESH TEXT INDEX txt_index_manual ON GROUPO.MarketingInformation;
TRUNCATE TEXT INDEX txt_index_manual ON GROUPO.MarketingInformation;
The truncated text index is repopulated with data the next time it is refreshed.
