Question

有谁可以告诉我为什么当我的桌子上有匹配时这段代码没有返回任何值？

CREATE FUNCTION fn_AllEmployeesAndTownsWhichContainLetters(@setOfLetters NVARCHAR(200), @string NVARCHAR(200))
    RETURNS BIT 
        AS
        BEGIN 
            DECLARE @length INT, @i INT
            SET @length = LEN(@string)
            SET @i = 1      
            WHILE (@i < @length)
                BEGIN
                    IF CHARINDEX(SUBSTRING(@string, 1, @i),@setOfLetters) <= 0
                        RETURN 0
                    ELSE
                        SET @i = @i + 1
                END
            RETURN 1
        END GO
