Invoked once for that table with a column name that is an empty string. Table") then the SQLite3::READ authorizer callback is When a table is referenced by a SELECT but no column values areĮxtracted from that table (for example in a query like "SELECT count(*) FROM SQLite3::IGNORE return can be used to deny an untrusted user SQLite3::IGNORE then the prepared statement isĬonstructed to substitute a null value in place of the table column that would haveīeen read if SQLite3::OK had been returned. If the action code is SQLite3::READ and the callback returns The call that triggered the authorizer will fail with an error message explaining that When the callback returns SQLite3::OK, that means the operation View that is responsible for the access attempt or null if this access attempt is The 5th parameter to the authorizer callback is the name of the inner-most trigger or The 4th parameter will be the name of the database ( "main", List of action codes and parameters Actionįirst argument passed to the pragma, or null Theįollowing table describes the second and third parameters according to the action: The other parameters are only passed for some actions.

A SELECT or UPDATE query will call theĪuthorizer for every column that would be read or updated. The authorizer callback may be called multiple times for each statement prepared by Place while the user-entered SQL is being prepared that disallows everything except But the application does not want the user toīe able to make arbitrary changes to the database. SQL queries for evaluation by a database. For example, an application may allow a user to enter arbitrary This is used when preparing a SQL statement fromĪn untrusted source to ensure that the SQL statements do not try to access data theyĪre not allowed to see, or that they do not try to execute malicious statements thatĭamage the database.
