语法:
CREATE [OR REPLACE] FUNCTION function_name (arguments)
RETURNS return_datatype AS $variable_name$
DECLARE
declaration;
[...]
BEGIN
< function_body >
[...]
RETURN { variable_name | value }
END; LANGUAGE plpgsql;
参数说明
function_name
:指定函数的名称。[OR REPLACE]
:是可选的,它允许您修改/替换现有函数。RETURN
:它指定要从函数返回的数据类型。它可以是基础,复合或域类型,或者也可以引用表列的类型。function_body
:function_body
包含可执行部分。plpgsql
:它指定实现该函数的语言的名称
#时间函数
