◆ errorMessage()
| QString spatialite_database_unique_ptr::errorMessage | ( | ) | const |
Returns the most recent error message encountered by the database.
Definition at line 97 of file qgsspatialiteutils.cpp.
◆ open()
| int spatialite_database_unique_ptr::open | ( | const QString & | path | ) |
Opens the database at the specified file path.
Returns the sqlite error code, or SQLITE_OK if open was successful.
Definition at line 44 of file qgsspatialiteutils.cpp.
◆ open_v2()
| int spatialite_database_unique_ptr::open_v2 | ( | const QString & | path, |
| int | flags, | ||
| const char * | zVfs | ||
| ) |
Opens the database at the specified file path.
Returns the sqlite error code, or SQLITE_OK if open was successful.
Definition at line 68 of file qgsspatialiteutils.cpp.
◆ prepare()
| sqlite3_statement_unique_ptr spatialite_database_unique_ptr::prepare | ( | const QString & | sql, |
| int & | resultCode | ||
| ) |
Prepares a sql statement, returning the result.
The resultCode argument will be filled with the sqlite3 result code.

◆ reset() [1/2]
| void spatialite_database_unique_ptr::reset | ( | ) |
Will close the connection and set the internal pointer to nullptr.

It is not allowed to set an arbitrary sqlite3 handle on this object.
A dedicated spatialite context (connection) is created when calling open or open_v2. This context needs to be kept together with the handle, hence it is not allowed to reset to a handle with missing context.
