Ok. Here we go. Time for some good ol' fashioned "Black Arts". 🙂

The first thing is, is to understand the true nature of the data-file example that was posted. I did that by "quoting the post" that had the example and some remarkable stuff showed up that the HTML rendering on this site was hiding. There's a ton of leading and embedded spaces. Here's what the file data really looks like...

The blank line actually contain 4 spaces. To help us see the spaces, I changed them all to a dash so they're easier to see.

That's almost a fixed field format. In fact, the data to the right of what I'm calling the "RowType" is the only place where it's not fixed field. It's "ragged right" but it does start in the same position in the line even for the "next line extension" of the OPT RowType. That's EASY.

The first thing to do is build a BCP FORMAT FILE to control the import. I recommend creating a new directory somewhere on the server itself to hold such format files. Save the following as a format file. On my test box, I saved it under "C:\SQL Examples\BulkData.fmt".

9.0

4

1 SQLCHAR 0 4 "" 0 Blanks01 ""

2 SQLCHAR 0 3 "" 2 RowType ""

3 SQLCHAR 0 2 "" 0 Blanks02 ""

4 SQLCHAR 0 8000 "\ n\r" 3 BulkData "" <-----<<<< Take the space out between the \ and the n. This site "consumes" backslash n as a control character.

The BCP FORMAT FILE skips the 4 spaces at the beginning of each line, picks up the next 3 characters (spaces or not) as the RowType, skips 2 more spaces, and then picks up to the next 8000 characters (ending with a carriage return/line feed) as the "bulk data" for each RowType.

The rest is pretty easy. I saved your file data example as "C:\SQL Examples\Weird Telephone File.txt". You'll, of course, need to change that and the location of the BCP FORMAT FILE. If all of this works out according to you, then I'll show you how to parameterize those two file paths so that you could turn this into a stored procedure.

Here's the code. As normal, the details are in the comments in the code.

--===== If the work table exists, drop it to make reruns in SSMS easier.

IF OBJECT_ID('tempdb..#BulkData','U') IS NOT NULL

DROP TABLE #BulkData

;

--===== Create the work table with the quintessential CLUSTERED index on

-- the RowNum column.

CREATE TABLE #BulkData

(

RowNum INT IDENTITY(1,1) PRIMARY KEY CLUSTERED

,RowType CHAR(3)

,BulkData VARCHAR(8000)

,DN CHAR(8)

)

;

--===== Using the previously constructed BCP FORMAT FILE,

-- load the file into the work table.

-- Because of the structure of the file and the BCP FORMAT FILE,

-- this will skip the blank rows, as well. Makes life real easy.

BULK INSERT #BulkData

FROM 'C:\SQL Examples\Weird Telephone File.txt'

WITH (

FORMATFILE = 'C:\SQL Examples\BulkData.fmt'

,FIRSTROW = 3

,TABLOCK

)

;

--===== Declare a "per row" variable that will be updated for every row.

-- Think "pseudo-cursor" here where we use the natural looping behind

-- the scenes of the UPDATE as if it were a declared cursor.

DECLARE @DN CHAR(8)

;

--===== Using the old fashioned method of a "Quirky Update",

-- do a "data smear" to copy each DN entry "down" to the next rows

-- until we hit another DN entry and then copy that "down", etc.

-- This is where we also assign a RowType to prep for the pivoting

-- that we'll do using an old fashiond CROSSTAB.

-- Notice that this is where we also create the "OFL" or "OVERFLOw"

-- RowType for the "OPT" row "extensions".

-- Heh... when I say "old fashioned", think "Black Arts".

UPDATE tgt

SET @DN = DN = CASE WHEN RowType = 'DN' THEN LEFT(BulkData,8) ELSE ISNULL(@DN,'') END

,RowType = CASE WHEN RowType = '' AND RTRIM(LTRIM(BulkData)) <> 'STN' THEN 'OFL' ELSE RowType END

,BulkData = LTRIM(RTRIM(BulkData))

FROM #BulkData tgt WITH(TABLOCKX,INDEX(1))

OPTION (MAXDOP 1)

;

--===== Let's see what we have in the work table...

SELECT * FROM #BulkData

;

--===== Now, let's simultaneously pivot and parse the data using a very high performance CROSSTAB.

SELECT PhoneNumber = DN

,StationCode = MAX(CASE WHEN RowType = 'LOC' THEN RTRIM(SUBSTRING(BulkData,1,CHARINDEX(' ',BulkData))) ELSE '' END)

,Port = MAX(CASE WHEN RowType = 'LOC' THEN RTRIM(LTRIM(SUBSTRING(BulkData,CHARINDEX(' ',BulkData),8000))) ELSE '' END)

,Options = MAX(CASE WHEN RowType = 'OPT' THEN RTRIM(BulkData) ELSE '' END)

+ MAX(CASE WHEN RowType = 'OFL' THEN ' '+LTRIM(RTRIM(BulkData)) ELSE '' END)

FROM #BulkData

GROUP BY DN

;

This is what ends up in the "work" table... (scroll-right to see the new "DN" column)

RowNum RowType BulkData DN

Notice how the DN has been "smeared down" for all rows where it first occurs until a new DN row shows up and then that is "smeared down", etc, etc. That's the key that we GROUP on to do the CROSS APPLY to pivot everything and to combine the any existing OFL rows with their respective OPT rows.

Here's what the final output looks like courtesy of the CROSS APPLY.

This is the "easy" part, so far. If that's ok by you, the next part would be to split the options (OPT) into separate columns but, I have to ask, do you REALLY want to do that?

Nicely done, Jeff. I'm filing this one away for later, as I'm sure the approach will come in handy some day.

There's a correction that I just made in the original post because this site ate the backslash N. In your quotes above, the \ n\r should be \r\ n (with the appropriate space removal). I had originally pasted the \ n into the wrong spot apparently due to caffeine depletion in the bloodstream. :blush:

I also do absolutely agree with Koen that SSIS does make some things (like gated parallel processing) a whole lot easier. If you combine the features of SSIS with the ability for it to call upon stored procedures and the like, it can be a formidable tool.

@Koen...

Is there a way to easily copy packages from one instance of SSIS to another? THAT would make it even more formidable.

@jeff Yes the the OPTion values have to be separated. There is a catch though when separating the OPTions:

1. the paymode is determined from the OPTions, if OPTions contain any one or more of these values: !124,32,82,13,34,38,!RIT,!TDK then its a Prepaid, if in these values: 3,52,DMS10i,58,4,DMS100,8,19,5,9,21,10,7,26,2,37 then its a postpaid. If none of the values are specified, then the default Postpaid.

2. From all possible values of OPTions, the only OPTions' columns needed are:

!BAR !ECO !IDD !LOC !NPA !OPR !STD !VAS 1FR 1MR ACT ALTO AWS CDF CFAN CFB CFBU CFD CFDU CFW CLT CND CNDB COB CWT DGT DNH DOR DTM ENQC FNT FPSV FREQ FRST MCT MTR NACT OCB OPT RTP SUS SUSO SUST VM

Thank you.

Sorry about the long quote above. I wanted to keep this all together. And, sorry about the delay. I was on vacation last week and forgot all about it.

Getting back on track, the following will do what you've asked for in the last post above. It uses the same BCP Format File, the same file, and almost all of the code is the same except for how we split up the "BulkData" column.

The first thing that you'll need to do is to build the "DelimitedSplit8K" function in whatever database you're doing all of this. It's a fully documented splitter function. You can get the function from the "Resources" section near the bottom of the article at the following link.

http://www.sqlservercentral.com/articles/Tally+Table/72993/

Once you've installed the "DelimitedSplit8K" function above, the following code will do as you've asked...

/* BCP Format File used (same as previous)

9.0

4

1 SQLCHAR 0 4 "" 0 Blanks01 ""

2 SQLCHAR 0 3 "" 2 RowType ""

3 SQLCHAR 0 2 "" 0 Blanks02 ""

4 SQLCHAR 0 8000 "\r\ n" 3 BulkData "" <-----<<<< Take the space out between the \ and the n. This site "consumes" backslash n as a control character.

Again, sorry for the delay and thanks for the problem. This was fun. If you have any questions about how this thing works, please post back. If I can't get back to it, the heavy hitters on this forum are pretty familiar with all of these techniques and I'm sure that they'll be happy to answer in my stead.
