Extracting a String Within Delimeters - Part 2

  • There is a typo in the SELECT code, needs to be


    SELECT Particulars,


           /* <text>> */ Particulars,

           /* <start > */   CHARINDEX(';',Particulars,1) + 1,

           /* <length> */   CHARINDEX(';',

              SUBSTRING(Particulars, CHARINDEX(';', Particulars, 1) + 1, 99) + ';') - 1

          ) ) ) AS Result_string

    FROM Sample_table

  • The innermost SUBSTRING will yield this:

     LUC20031026901 ; Vehicle


     SUB35030172701 ; Building

     LIQ200310121 ; Liquor

    and when the semicolon is added, it will look like this:

     LUC20031026901 ; Vehicle                                                                          ;

     Consolidated                                                                                      ;

     SUB35030172701 ; Building                                                                         ;

     LIQ200310121 ; Liquor                                                                             ;

  • Wouldn't it be easier to just use:

    SELECT RIGHT(RTRIM(Particulars), LEN(RTRIM(Particulars)) - CHARINDEX(';',Particulars) - 1)

    FROM Sample_table

    Also, you could remove the RTRIMs if you used VARCHAR instead of CHAR...

  • drop table Sample_table

    CREATE TABLE #Sample_table (Particulars varchar(120))


    INSERT INTO #Sample_table VALUES('LDR ; LUC20031026901 ; Vehicle')

    INSERT INTO #Sample_table VALUES('LDR ; Consolidated                                                     ')

    INSERT INTO #Sample_table VALUES('LDR ; SUB35030172701 ; Building')

    INSERT INTO #Sample_table VALUES('LDRR ; LIQ200310121 ; Liquor')

    select * from #Sample_table

    SELECT Particulars,

    --    quotename( -- enable this to see, that's just the string without spaces around



       /*from*/CHARINDEX(';',Particulars,1)+1,   -- search first delimiter and then offset 1 from first deliminter

       /* to */CHARINDEX(';',                    -- search for the next delimter as the end-of-string

         SUBSTRING (Particulars,

             /*from*/    (CHARINDEX (';', Particulars,1)+1) -- the first character after first delimiter

             /* to */   , datalength(Particulars)     -- use datalength for not beeing bound to specific length

             ) + ';'  -- for any case add a delimiter (this was a good idea from Denis Oliynik !!), if it's an additonal, it's just lost

          ) - 1  -- delimiter Position minus one    


         ) -- rigth parenthesis for lrim

           ) -- rigth parenthesis for rtrim

    --&nbsp rigth parenthesis for quotename

    FROM #Sample_table

    /* commet out ltrim/rtrim to extract the whole string with spaces

    This is a very general select not delimited to programmed stringlenthes or varchar's etc. It just extracts the first delimited string within another string, not more or less.

  • Thanks for the feedback. The typo occurred in translation from the submitted MS/Word document to the HTML page and was an accident by the publisher that I did not pick up on. Please accept my apologies for this.
