如何确定SQL Server中的数字是浮点数还是整数？

Question

我需要在sql server中编写这个查询:

IF isFloat(@value) = 1
BEGIN
    PRINT 'this is float number'
END
ELSE
BEGIN
    PRINT 'this is integer number'
END

请帮帮我,谢谢.

Answer 1

declare @value float = 1

IF FLOOR(@value) <> CEILING(@value)
BEGIN
    PRINT 'this is float number'
END
ELSE
BEGIN
    PRINT 'this is integer number'
END
