Solution 1

Hi,

Write a loop in SQL that loops through the string and makes use of CHARINDEX[^] and SUBSTRING[^], and then count the number of separators (till the end of the string).

Kind regards,

SQL

DECLARE @Ids NVARCHAR(255)
SET @Ids ='as,sdf,dsaf,sdfsd'

DECLARE @ID varchar(32), @Pos int , @commcount bigint


    SET @Ids = LTRIM(RTRIM(@Ids))+ ','
    SET @Pos = CHARINDEX(',', @Ids, 1)
SET @commcount=0
    IF REPLACE(@Ids, ',', '') <> ''
    BEGIN
        WHILE @Pos > 0
        BEGIN
            SET @ID = LTRIM(RTRIM(LEFT(@Ids, @Pos - 1)))
            IF @ID <> ''
            BEGIN
                SET @commcount = @commcount + 1
            END
            SET @Ids = RIGHT(@Ids, LEN(@Ids) - @Pos)
            SET @Pos = CHARINDEX(',', @Ids, 1)

        END
    END

select (@commcount-1)

One option is to use this:

SQL

Declare @string varchar(1000)
Set @string = 'a,b,c,d'
select len(@string) - len(replace(@string, ',', ''))

pl check the following thread for other options:

Solution 4

i simply solved it as

select len('ddddddsdsgfgvddd')-len(replace('ddddddsdsgfgvddd','s',''))

It will count how many 's' occured in string
