Oracle full-text search

Using like %, Oracle performs a full table scan, which consumes system resources. This allows you to use full-text retrieval of oracle to increase the query speed. Before creating a synchronization and optimized storage process, you must use the sys user to grant permissions to evan users: grantexecuteonctx_ddltoevan; otherwise, SQLcreateorreplace will be reported.

Using like '%', Oracle performs a full table scan, which consumes a considerable amount of system resources. This allows you to use full-text retrieval of oracle to increase the query speed.
