Question

为什么在sql sever中使用format对文字格式化，提示为：'FORMAT' 不是可以识别的 内置函数名称

create table products
(prod_id int,
productname varchar(20),
unit varchar(20),
unitprice float);
insert into products values('1','gold','1000g','32.35');
insert into products values('2','silver','1000g','11.56');
insert into products values('3','copper','1000g','6.85');
SELECT productname, unitprice, FORMAT(getdate(),'YYYY-MM-DD') as PerDate FROM products;

SQL Server 里面执行一下， 看看你需要哪一种格式。

Answer 2

format在SQL SERVER上不能用，SQL SERVER上规范日期格式是用CONVERT（），FORMAT在ACCESS中能用。

Answer 3

SELECT productname, unitprice,
convert(varchar,getdate(),23) as PerDate
FROM products

Answer 4

SELECT productname, unitprice, FORMAT(getdate(),'YYYY-MM-DD') as PerDate FROM products

改为
SELECT productname, unitprice, CONVERT(DATE, getdate()) as PerDate FROM products

追问

请问下为什么我上面提交的那个不可以，如果我想要将perdate的格式设置为yyyy/mm/dd或者yyyy.mm.dd呢？
