1.Convert.ToInt是数据类型转换成int类型 2. 有三种方法toint16,toint32,toint64 int16-数值范围:-32768 到 32767 int32-数值范围:-2,147,483,648 到 2,147,483,647 int64-数值范围:-9223372036854775808 到 9223372036854775808 3.所以,按需使用吧
SELECT CONVERT(INT, '42') AS IntegerValue; 在这个示例中,我们将字符串'42'转换为整数类型。 4、将数值类型转换为字符串类型: SELECT CONVERT(VARCHAR(10), 42) AS StringValue; 在这个示例中,我们将整数42转换为字符串类型。 需要注意的是,CONVERT()函数在不同的数据库管理系统中可能存在差异,在某些数据库...
