R-15107-48632-28569-47708-49546-63224-06623-07526 tcl slt th3 src

The authorizer callback is invoked as SQL statements are being compiled by sqlite3_prepare() or its variants sqlite3_prepare_v2(), sqlite3_prepare_v3(), sqlite3_prepare16(), sqlite3_prepare16_v2(), and sqlite3_prepare16_v3().

At various points during the compilation process, as logic is being created to perform various actions, the authorizer callback is invoked to see if those actions are allowed.

R-31386-03131-57152-48354-62931-03354-07372-50774 tcl slt th3 src

The authorizer callback should return SQLITE_OK to allow the action, SQLITE_IGNORE to disallow the specific action but allow the SQL statement to continue to be compiled, or SQLITE_DENY to cause the entire SQL statement to be rejected with an error.

R-64962-58611-23755-17940-51440-03163-56069-63868 tcl slt th3 src

If the authorizer callback returns any value other than SQLITE_IGNORE, SQLITE_OK, or SQLITE_DENY then the sqlite3_prepare_v2() or equivalent call that triggered the authorizer will fail with an error message.

R-04452-49349-54233-41206-52506-27116-05869-21475 tcl slt th3 src

When the callback returns SQLITE_DENY, the sqlite3_prepare_v2() or equivalent call that triggered the authorizer will fail with an error message explaining that access is denied.

The first parameter to the authorizer callback is a copy of the third parameter to the sqlite3_set_authorizer() interface.

The second parameter to the callback is an integer action code that specifies the particular action to be authorized.

R-43249-19882-52899-37517-44560-32908-46536-34852 tcl slt th3 src

The third through sixth parameters to the callback are either NULL pointers or zero-terminated strings that contain additional details about the action to be authorized.

R-38392-49970-12862-30349-17432-31139-60846-54763 tcl slt th3 src

If the action code is SQLITE_READ and the callback returns SQLITE_IGNORE then the prepared statement statement is constructed to substitute a NULL value in place of the table column that would have been read if SQLITE_OK had been returned.

R-31520-16302-20553-09634-49353-53000-23080-58537 tcl slt th3 src

When a table is referenced by a SELECT but no column values are extracted from that table (for example in a query like "SELECT count(*) FROM tab") then the SQLITE_READ authorizer callback is invoked once for that table with a column name that is an empty string.

If the action code is SQLITE_DELETE and the callback returns SQLITE_IGNORE then the DELETE operation proceeds but the truncate optimization is disabled and all rows are deleted individually.

/* IMP: R-17228-37124 */

Only a single authorizer can be in place on a database connection at a time. Each call to sqlite3_set_authorizer overrides the previous call.

When sqlite3_prepare_v2() is used to prepare a statement, the statement might be re-prepared during sqlite3_step() due to a schema change.
