Splitting the string in sql server

database, sql, sql-server, string

Solution

Try this function

CREATE FUNCTION [dbo].[func_Split] 
    (   
    @DelimitedString    varchar(8000),
    @Delimiter              varchar(100) 
    )
RETURNS @tblArray TABLE
    (
    ElementID   int IDENTITY(1,1),  -- Array index
    Element     varchar(1000)               -- Array element contents
    )
AS
BEGIN

    -- Local Variable Declarations
    -- ---------------------------
    DECLARE @Index      smallint,
                    @Start      smallint,
                    @DelSize    smallint

    SET @DelSize = LEN(@Delimiter)

    -- Loop through source string and add elements to destination table array
    -- ----------------------------------------------------------------------
    WHILE LEN(@DelimitedString) > 0
    BEGIN

        SET @Index = CHARINDEX(@Delimiter, @DelimitedString)

        IF @Index = 0
            BEGIN

                INSERT INTO
                    @tblArray 
                    (Element)
                VALUES
                    (LTRIM(RTRIM(@DelimitedString)))

                BREAK
            END
        ELSE
            BEGIN

                INSERT INTO
                    @tblArray 
                    (Element)
                VALUES
                    (LTRIM(RTRIM(SUBSTRING(@DelimitedString, 1,@Index - 1))))

                SET @Start = @Index + @DelSize
                SET @DelimitedString = SUBSTRING(@DelimitedString, @Start , LEN(@DelimitedString) - @Start + 1)

            END
    END

    RETURN
END

Example Usage – simply pass the function the comma delimited string as well as your required delimiter.

DECLARE @SQLStr varchar(100)
SELECT @SQLStr = 'Mickey Mouse, Goofy, Donald Duck, Pluto, Minnie Mouse'

SELECT
    *
FROM
    dbo.func_split(@SQLStr, ',')

Result will be like this

Problem

I have a string in the database which is comma separated.Like 'apple,banana,pineapple,grapes' I need to split this string on the basis of comma and iterate through this.Since there is no built in function in sql server, Is there any efficient way in which this objective can be attained.
