Metadata provides structural details about your SQLite database, including tables, columns, data types, primary and foreign keys, and other schema-level details.
In most cases, metadata is requested automatically by an application using the ODBC driver. The application initiates metadata requests using standard ODBC functions such as SQLTables and SQLColumns. The driver fetches the requested metadata from SQLite and returns it to the application.
Metadata can also be retrieved manually by using PRAGMA statements.
For more information on accessing metadata through ODBC functions or PRAGMA statements, see Access metadata.
