Examples of org.eigenbase.sql.SqlFunction

org.eigenbase.sql.SqlFunction
A SqlFunction is a type of operator which has conventional function-call syntax.

          String newFunctionName = functionName + literal;


          // Look up the new function name in the drill operator table
          List<SqlOperator> operatorList = table.getSqlOperator(newFunctionName);
          assert operatorList.size() > 0;
          SqlFunction newFunction = null;


          // Find the SqlFunction with the correct args
          for (SqlOperator op : operatorList) {
            if (op.getOperandTypeChecker().getOperandCountRange().isValidCount(nArgs - 1)) {
              newFunction = (SqlFunction) op;
