我使用Postgres上的SQL语言使用RETURNS TABLE命令返回一个表:

CREATE OR REPLACE FUNCTION procreadbudget()
  RETURNS TABLE(budgetmonth character, budgetincome numeric, budgetexpense numeric) AS
$BODY$
SELECT budget_month, budget_income, budget_expense FROM budget ORDER BY unique_id;
$BODY$
  LANGUAGE 'sql' VOLATILE

所有数据都以逗号分隔的字符串形式返回,而不是作为表格返回:

"(Jan,1123,1201)"
"(Feb,1098,996)"
"(Mar,1545,1345)"
"(Apr,1564,1952)"
"(May,1123,990)"
"(Jun,1345,1234)"
"(Jul,1234,878)"
"(Aug,1139,1187)"
"(Sep,1076,1123)"
"(Oct,873,956)"
"(Nov,1298,1423)"
"(Dec,1123,1324)"

迈克,请你提出任何建议
