| - | ===== Discussion ===== | ||
| - | |||
| - | ==== UPDATE INDEXES ==== | ||
| - | If no qualifier is specified, the UPDATE INDEXES statement will build all the Omnidex Indexes for the connected Omnidex Environment. | ||
| - | ==== UPDATE INDEXES FOR environment_object ==== | ||
| - | A specific Database, Table, Column, or Index object can be specified to limit the area to build the indexes. | ||
| - | |||
| - | update indexes for database db1; | ||
| - | |||
| - | update indexes for table trans_table; | ||
| - | |||
| - | update indexes for column trans_table.trans_date; | ||
| - | |||
| - | ==== WITH Options ==== | ||
| - | LOG=<directory> will cause Omnidex to write indexing logs to the specified directory. This is particularly useful for reviewing the status of large UPDATE INDEX operations. | ||
| - | |||
| - | update indexes with log="odxlogs"; | ||
| - | |||
| - | BUF=mega_bytes is used to increase the internal size of indexing buffers used by the Omnidex indexing operation. | ||
| - | |||
| - | UPDATE INDEXES WITH BUF=1024 | ||
