Member Function Documentation
◆ execute()
|
protectedpure virtual |
For implementation, executes the prepared statement Type of statement is specified by the type parameter.
selectFieldList specifies fields for SELECT statement. insertFieldList is set to list of fields in INSERT statement. Parameters parameters are passed to the statement, usually using binding.
Implemented in SqlitePreparedStatement.
◆ prepare()
|
protectedpure virtual |
For implementation. Initializes the prepared statement in a backend-dependent way using recently generated sql statement. It should be guaranteed that sql is valid and not empty. For example sqlite3_prepare() is used for SQLite. This is called only when d->dirty == true is encountered on execute(), i.e. when attributes of the object (like WHERE field names) change.
Implemented in SqlitePreparedStatement.
