decimal数据类型在结果网格中将显示有效小数位: 12.50 (5).精度和小数位数的默认值分别是18与0。如果在decimal类型中不提供这两个值,SQL Server将截断数字的小数部分,而不会产生错误。 SELECT CAST('12.5' AS decimal) 结果是一个整数值:12 SQL中CONVERT函数格式: CONVERT(data_type,expression[,style]) 参数说明...
SELECT CAST('12.5' AS int) (3).CAST()函数和CONVERT()函数都不能执行四舍五入或截断操作。由于12.5不能用int数据类型来表示,所以对这个函数调用将产生一个错误: Server: Msg 245, Level 16, State 1, Line 1 Syntax error converting the varchar value '12.5' to a column of data type int. (4)....
