Overview

OceanBase Connector/C is an OceanBase client development component based on C/C++. OceanBase Connector/C supports the C API library.

OceanBase Connector/C allows C/C++ programs to access OceanBase distributed database clusters from the underlying layer to perform operations such as database connection, data access, error handling, and prepared statement processing.

OceanBase Connector/C, also known as LibOBClient, is used by applications as an independent server process to communicate with OBServers based on network connections. A client references the C API header file during compilation and can connect to the C API library file. Note

The so file generated by LibOBClient is libobclnt.so, which is equivalent to libmysqlclient.so. After you install OceanBase Database, you can use the command-line tool OceanBase Client (OBClient), which is equivalent to a MySQL command-line tool.
