Member Function Documentation

toSQL()

void te::da::BinaryOpEncoder::toSQL ( const Function &  f, std::string &  buff, SQLVisitor &  v  ) const

virtual

It encodes the function to a SQL notation.

This method will encode the function in infix binary operator notation: (firstOperand op secondOperand). For example, the '+' function is encoded as: (A + B).

Parameters

f	The function to be translated to a SQL notation.
alias	The function alias in the data source query language.
buff	The destination string buffer where the translation will be written.
v	The SQL visitor that will be used to visit the arguments expression.

Implements te::da::SQLFunctionEncoder.
