在SQL Server中,可以使用CAST函数将int类型的数据转换为字符串类型的数据。CAST函数是SQL Server的内置函数,用于将一个数据类型转换为另一个数据类型。下面是使用CAST函数进行int转字符串的示例: DECLARE@numINTSET@num=123DECLARE@strVARCHAR(50)SET@str=CAST(@numASVARCHAR(5
1.SELECT CAST(‘9.0’ AS decimal) 结果:9 2.SELECT CAST(‘9.5’ AS decimal(10,2)) 结果:9.50(精度与小数位数分别为10与2。精度是总的数字位数,包括小数点左边和右边位数的总和。而小数位数是小数点右边的位数) 3.SELECT CAST(NOW() AS DATE) 结果:2017-11-27 now() 2017-11-27 10:43:22...

If $arg is an atomic value, the function returns the same string that is returned by the expression cast as xs:string, $arg, except when noted otherwise. If the type of $arg is xs:anyURI, the URI is converted to a string without escaping special characters. Inthis implementation, fn:st...
CAST 和CONVERT执行DATE` 数据类型转换。 日期字符串 第一个参数指定一个日期字符串文字。可以为输入 date_string 提供任何类型的日期字符串。每个字符都必须对应于格式字符串,但以下情况除外: 可以包含或省略前导零(不带分隔符的 date_string 除外)。 年份可以用两位数或四位数字指定。 月份名称可以完整指定,也可...
