首先,我们需要创建一个自定义函数,用于实现LEAST函数的功能。可以使用以下代码创建函数: CREATEFUNCTIONdbo.LEAST(@Value1<数据类型>,@Value2<数据类型>,...)RETURNS<数据类型>ASBEGIN-- 函数逻辑将在下一步实现END 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 4. 定义函数参数 在上一步创建的函数中,我...

如果列是由1开始的枚举值,可以用CHOOSE来转成对应的文字描述 GREATEST和LEAST 这两个是后面才有的,GREATEST可以输出多个列中最大的的列值,有点像列级别的MAX函数。而LEAST就是反过来,多列中的最小值。这里需要注意对NULL值的处理。 IIF 这个可以理解为对CASE WHEN的简化,相当于XML和JSON,CASE WHEN和IIF。
The LEAST function requires at least one argument and supports no more than 254 arguments.Each expression can be a constant, variable, column name or function, and any combination of arithmetic, bitwise, and string operators. Aggregate functions and scalar subqueries are permitted....
