This is an example of a C++ function that returns the current version of chDB as a string. The version number is defined using the CHDB_VERSION_STRING macro, which should be defined during the build process. The FunctionChdbVersion class is a subclass of FunctionConstantBase, which is a base class for functions that return a constant value. The FunctionChdbVersion constructor takes the CHDB_VERSION_STRING macro as an argument, which is passed to the FunctionConstantBase constructor to set the constant value of the function. The REGISTER_FUNCTION macro is used to register the FunctionChdbVersion function with the FunctionFactory. The REGISTER_FUNCTION macro should be conditionally compiled using an #if directive that checks whether the CHDB_VERSION_STRING macro is defined, to avoid registering the function if the version number is not available.

This PR adds a simple
chdb()function with no parameters that returns the current version of chDB as a string.The version number is defined using the
CHDB_VERSIONmacro, which should be defined during the build process.The function is conditionally compiled using an
#ifdirective that checks whether theCHDB_VERSION_STRINGmacro derived fromCHDB_VERSIONis defined, to avoid building and registering the function if the version number is not available.Changelog category (leave one):
