The download package contains usage examples in the directory examples/. These
examples explain how to use the following classes:
Connection
Driver
PreparedStatement
ResultSet
ResultSetMetaData
Statement
The examples cover:
Using the Driver class to connect to MySQL
Creating tables, inserting rows, fetching rows using (simple) statements
Creating tables, inserting rows, fetching rows using prepared statements
Hints for working around prepared statement limitations
Accessing result set metadata
The examples in this document are only code snippets, not complete programs. The code snippets provide a brief
overview on the API. For complete programs, check the examples/ directory of your
MySQL Connector/C++ installation Please also read the README file in that
directory. To test the example code, edit the examples.h file in the examples/ directory to add your connection information, then rebuild the code by
issuing a make command.
The examples in the examples/ directory include:
examples/connect.cpp:
How to create a connection, insert data into MySQL and handle exceptions.
examples/connection_meta_schemaobj.cpp:
How to obtain metadata associated with a connection object, for example, a list of tables, databases, MySQL version, connector version.
examples/debug_output.cpp:
How to activate and deactivate the MySQL Connector/C++ debug protocol.
examples/exceptions.cpp:
A closer look at the exceptions thrown by the connector and how to fetch error information.
examples/prepared_statements.cpp:
How to run Prepared Statements including an example how to handle SQL statements that cannot be prepared by the MySQL Server.
examples/resultset.cpp:
How to use a cursor to fetch data and iterate over a result set.
examples/resultset_meta.cpp:
How to obtain metadata associated with a result set, for example, number of columns and column types.
examples/resultset_types.cpp:
Result sets returned from metadata methods. (This is more a test than an example.)
examples/standalone_example.cpp:
Simple standalone program not integrated into regular CMake builds.
examples/statements.cpp:
How to execute SQL statements without using Prepared Statements.
examples/cpp_trace_analyzer.cpp:
This example shows how to filter the output of the debug trace. Please see the inline comments for further documentation. This script is unsupported.
