T-sql String Parsing
Jul 11, 2006
I have a series of strings (field name FullName) in a table (FullNames) that look like this:
FullNames
--------------
macdonald, ronald
Doe, John
I need to extract the first and last names. Here's my code:
select substring (fullname, 1, patindex( '%,%', fullname)-1) + ' ' +
substring (fullname, patindex( '%,%', fullname)+1, len(fullname) ) from FullNames
I hate having to use patindex twice in the same SELECT. Is there any way around this?
TIA,
Barkingdog

I found an article about string parsing but its done using db2
http://www.ibm.com/developerworks/db2/library/techarticle/0303stolze/0303stolze1.html
can anybody translate to Transact SQL specifically the example of create function elemIdx i didnt understand how he used recursion may b cuz the language is odd to me i didnt get it
Thanks much

I have a string that is coming from a legacy system
###T1937###U1875###U1960###U3287###U5926###U6388###U4408###T1909###U2620###U5025###U6354###U7072###U7074###U6715###U6714###U4085###U6441###U7067###U7073###U2392###U6348###U7758###U6717###U7755###U7069###U7756###U6350###U6760###U7070###D0002###D0001###U6238###U6349###U6353###U6355###F0005###U7750###U6351###U7757###
How can I convert above string to comma separted values
like one below so that it can be used for IN Clause for my SQL
'T1937','U1875','U1960','U3287','U5926','U6388','U4408','T1909','U2620','U5025','U6354','U7072','U7074','U6715','U6714','U4085','U6441','U7067','U7073','U2392','U6348','U7758','U6717','U7755','U7069','U7756','U6350','U6760','U7070','D0002','D0001','U6238','U6349','U6353','U6355','F0005','U7750','U6351','U7757'
Thanks in advance

Hi everybody, I was hoping to get some advice something I can't quite get my head around. I have a SQL db which contains a table with ratings using the AJAX rating control.
When someone rates an object, I need to select the current rating and then use those numbers to;
- calculate the new average
- add new score to total score
- increment number of votes by one.
I thought this can be best achieved using the SELECT statement and then parsing the SELECT string. (is the string comma separated?)
using each array, i'd need to convert this into integers and then do the calculation. and re-upload the data to the ratings table (using the UPDATE statement).
Is this the best way of proceeding? I have tried initially to write the code using three sql statements. But that would mean to many requests from the server, right?
Below is the conde I have writting already.int myrating;
myrating = Rating1.CurrentRating;string getscore = "SELECT " +
"RatingScore" +"FROM Rating " +
"WHERE ItemID= '" + _ItemID+ "'";string getcount = "SELECT " +
"RatingCount" +"FROM Rating " +
"WHERE ItemID = '" + _ItemID + "'";string getaverage = "SELECT " +
"RatingAverage " +"FROM Rating " +"WHERE ItemID = '" + _ItemID + "'";
int _ratingscore;int _newscore; _ratingscore = int.Parse(getscore);
_newscore = _ratingscore + myrating; //add new rating score to old scoreint _ratingcount;
int _newcount;_ratingcount = int.Parse(getcount);
_newcount = _ratingcount + 1; //increase count by 1int _ratingaverage;
int _newaverage;_ratingaverage = int.Parse(getaverage);
_newaverage = _newscore / _newcount; //calculate new average rating
otherwise
otherwise would i be best off to do the following?...
string[] dbRatings = SQLstring.Split(',');
??
Any help would be appreciated.
Many thanks in advance.
Phil

I'm running into a couple of performance issues with regards to the parsing of a text string. We have a function that will take a comma delimited character string, parse out the individual values, and then populate a temp table with those values. The two issues are 1.) the parsing process is VERY slow and 2.) there's a max to how large the string can be - at some point it could easily be 8000 characters or more in length.
Here are the function and the stored procedure wher eit occurs:
CREATE FUNCTION [dbo].[Split](@String varchar(MAX), @Delimiter char(1))
RETURNS @Results TABLE (Item nvarchar(4000))
AS
BEGIN
DECLARE @INDEX INT
DECLARE @SLICE nvarchar(4000)
-- HAVE TO SET TO 1 SO IT DOESNT EQUAL Z
-- ERO FIRST TIME IN LOOP
SELECT @INDEX = 1
WHILE @INDEX !=0
BEGIN
-- GET THE INDEX OF THE FIRST OCCURENCE OF THE SPLIT CHARACTER
SELECT @INDEX = CHARINDEX(@Delimiter,@STRING)
-- NOW PUSH EVERYTHING TO THE LEFT OF IT INTO THE SLICE VARIABLE
IF @INDEX !=0
SELECT @SLICE = LEFT(@STRING,@INDEX - 1)
ELSE
SELECT @SLICE = @STRING
-- PUT THE ITEM INTO THE RESULTS SET
INSERT INTO @Results(Item) VALUES(@SLICE)
-- CHOP THE ITEM REMOVED OFF THE MAIN STRING
SELECT @STRING = RIGHT(@STRING,LEN(@STRING) - @INDEX)
-- BREAK OUT IF WE ARE DONE
IF LEN(@STRING) = 0 BREAK
END
RETURN
END

Is there a faster / more efficient way to accomplish the above?
Any insight would be appreciated!!

I have a table Alert_Types with these fields :
alert_id,
alert_source,
body,
Now whenever a new alert is registered record goes in table like
alert_id = 1,
alert_source= document_detail_view,
body = Document ID: @document_id
Customer Name: @customer_name
Item name: @item_name
Quantity: @qty
it was simple to parse simple variables using replace functions. eg. REPLACE(@str, '@customer_name', @customer_name). It worked like mail merge.the converted string was then sent forward using a webservice.now my requirement is to add conditional values in body field e.g:
body = Document ID: @document_id
Customer Name: @customer_name
Item name: @item_name
Quantity: @qty
IF isnull(@rate, 0) > 0 Rate: @rate
IF isnull(@rate, 0) > 0 Amount: @amount
how can i parse strings like this. I'm open to change format of values for body field.

parsing any delimited string (in above example it is using ',' as parsing delimiter. This query can be useful in many business scenarios where in we have input data as a long string containing delimited values.
declare
v_sql VARCHAR2(2000);
v_pos INTEGER;
v_differentiator VARCHAR2(10);

I can't figure this one out. I don't have enough knowledge of the string functions I guess.
I need to pull a value out of a variable I setup in a for each loop. The value is the filename/path of each source file being processed. Let's say the variable that has the source file path is called VAR1.
One sort of off topic thing I've noticed is when watch the variable in bebug mode and I look at the value of VAR1 it has double back slashes. Here's an example of the value of VAR1:
"\\L3KRZR6.na.xerox.net\C$\Documents and Settings\ca051731\Desktop\Project4\DPT_20070926.ver"
How come the back slashes have been doubled? And do I need to account for that when I start parsing the string value?
Anyway, I need to grab part of the filename from VAR1 and I need the value populated at the start of the for each loop container - ideally when I capture VAR1 in the for each container. I'll be using the string in drop table, create table and create index statements before the actual Data Flow task within the overall package
In the above example I need to grab the characters before the underscore and after the last \. So I'd need the string "DPT" captured in this example.
The actual string could be 1 to 3 characters long, even though this example has it as 3 long.
Underscores could exist anywhere in the actual UNC path once this package is moved to our actual system environments so I can't key off of the underscore.
Because I can't count on the string being a fixed lenght I can't just use a positional string function and grab specific text starting/ending at specific points.
Is there a way to use the various string functions in the expression builder to grab the text between the right most underscore and the right most back slashes or something like that? Ideally I'd like to setup a new expression based packed scope variable called VAR2 and build it using string functions applied to VAR1.

Hi,
The suggestion to do this is buried deep in one of my posts, however I still do not have a clear idea of how to do this.
I have a flat file which has several "bad rows" in it. Because file error redirection is buggy, I need a manual approach to get rid of these incomplete rows in my data file.
Phil, you suggested I read the file as one long string, then parse out the bad rows (using a script?).... however I have no idea as to how to actually do this.
I was wondering if it's possible to clarify the steps involved in doing this, or perhaps point me to an example I can look at, as I cannot seem to get around this problem on my own.
Thanks much!!

Wondering what's the preferred method for this. I've got a scenario that a user is updating some content on a page and I need to update my word catalogs for my search feature. I have some code currently to filter out words that are too small, make sure there are no duplicates and to count how many occurrences there are of each. What I'm wondering is, does it make more sense to do a loop in my code to run all the insert commands to place the new words in the database, should I try sticking them together in one string and parse them when they get up there or is there a better method someone can suggest?

I'm trying to parse out a line of data that is separated by the text "atc1.", "atc2." etc.
For example,
[atc1.123/atc2.456/atc3.789/atc4.xyz/]
If I only want the data after atc2., then I could search the string for "atc2." and collect all the characters afterwards. But how can I make sure to trim off all the data after "atc3." to make sure I'm only collecting "456" from the example above?

I want to grab some key value pairs from the text in sql column
e.g.
some text[Key1=Val1]some text[Key2=Val2][Key3=Val3]some text
I want a function which takes Keyname as input & returns the value related with it if found.
GetValueFmKey('Key1') should return Val1 and like on.

I have a problem at the moment, where the client wants to be able to type in a custom algebraic formula with add/minus operators, and then to have this interpreted, so that the related datasets are then added and returned as a single dataset.
An example would be having a formula stored of [a] + [b] - [c]
and if I were to write the SQL to apply that formula, I might write something like (let's assume 1:1 relationships with the ID's)
select a.a + b.b - c.c as [result]
from z
inner join tblA a on z.id = a.id
inner join tblB b on z.id = b.id
inner join tblC c on z.id = c.id
The formula can change though, maybe things like:
[a] + [b] + [c] + [d]
[a] + [b]
The developer before me wrote something SQL-based where they parsed the string and assigned each value of the formula as either positive or negative (e.g A is positive, B is positive, C is negative, now sum the datasets to get the result), and then created one large table of values then summed them. This does (kind of) work, I'm just contemplating potential alternatives, as it is quite a slow process, and feels like it is quite convoluted, when I get into the details. If I were to do something like this in SQL, I'd normally want each part of the expression to be a column, and then to just apply the operators, but because the formula can change, then the SQL would need to be somehow dynamic for this approach.

I am trying to process an XML document that contains the attribute 'from_x'. However an openxml query can't seem to find any column with a '_x' suffix. For example if I were to execute the following fragment:
declare @hDoc int, @Message varchar(200)
select @Message = '<BACK_FM from_x="12"></BACK_FM>'
exec sp_xml_preparedocument @hDoc OUTPUT, @Message
select from_x from openxml(@hDoc, 'BACK_FM',1) with (from_x int)
I get back a null value from the openxml query. Attribute names 'fromx' and 'from_y' work ok but nothing I have tried with a trailing '_x' will work.
Does anyone know if this is a known SQL Server bug? Is it a bug at all or something about XML that I don't know about?
Thanks,
Wayne King

I need to figure out how to parse a comma separated value.
Lets say I have a variable equal to a comma separated list.
SET @Variable = '045, 032, 025, 653'
I need to create a dynamic sql string to look like:
SET @Variable = ''' + '045' + ''' + ',' + ''' + '032' + ''' + ',' etc...
Can someone teach me a optimized query to do this?
Thanks

Can you parse a SQL field? Let's say, FULLNAME field got a TEXT datatype with the following data: <firstname>Norm</firstname><lastname>bercasio</lastname><Color>blue</color>then using a select statement, parse the field to find the lastname then write it to another field called LASTNAME on the same table, same rowID. Can you send a select statement how it can be done? I am using SQL 2003 or 2005. thank you so much.

Hi All,
I'm using a SQL selection to fill a DataGrid. One of the fields I have is called diagnosis. This field in the database can contain multiple diagnosis. But I use a set of characters to divide each diagnosis.
Example : Sick!@#$%Hurt!@#$%Ill!@#$%
My problem is this is how it looks in my Data Grid. Can someone tell me how to parse out each diagnosis.
Thanks

Anybody out there ever take a column containing names and parse it out to salutation, first name, middle initial/name, last name, suffix using Transact-SQL? I think I know how to do it using an array in a procedural language, but using SQL I'm drawing a blank.
Any ideas or help will be appreciated!

I have a varchar field that contains answers to questions separated by commas. Say there are 4 questions for each user. Here is an example of what the table would look like:
User Answer
1 Good,Fair,Good,Bad
2 Bad,Good,Good,Good
3 Fair,Good,Bad,Fair
I need to write a stored procedure to report off of that separates the Answer field into 4 different columns. How can this be achieved? Any assistance would be greatly appreciated.

Hello everyone
Heres what it looks like:
I have a large file of over 40k email records. The emails are all mixed up and come in various formats but i noticed that most of them are in this format:
firstname.lastname@email.com
firstname.middlename.lastname@email.com
For all those emails with the period (.) in between, the (.) actually separates an individuals first and last name.
My task is this, to separate all the emails that are in this format into first and last name fields. I'm stimped folks and I'll really appreciate any pointers or ideas on how to go about solving this task.
Thanks

Parsing Address
This is not really a reply, but I saw the problem and the replies look very promissing.
I'm using ss2k, I have a table with an address column.
here is some example of the records under ADDRESS :
WILLOW CREEK PL
RED BARN DR
RED BARN DR
CARRINGTON DR
RENNER RD
EDMONTON CT
SPRINGBRANCH DR
HILLROSE DR
CEDAR RIDGE DR
LARTAN TRL
PRESIDENT GEORGE BUSH HWY
What I want to do is to write script that runs daily and parse the street names (RED BARN) and street types (Dr, PL , etc.. ) to 2 colums. As u can see there is no fixed length or fixed number of words ...etc ...
Any help would be really appreciated.
thnks

Hello everyone, I have this SP and can't get it to work on my SQL2000 server. I just can't seem to figure out what syntax error I am making.
(This works on my test SQL2005 server)
Truncate Table [SecurityEvents_Temp]
Insert Into SecurityEvents_Temp (
[BankNumber],
[UserName],
[DomainName],
[EventLog],
[RecordNumber],
[TimeGenerated],
[TimeWritten],
[EventID],
[EventType],
[EventTypeName],
[EventCategory],
[EventCategoryName],
[SourceName],
[Strings],
[ComputerName],
[SID],
[Message],
[Data]
)
Select
[BankNumber] = '001',
[UserName] = (Select [Value] From [dbo].[fn_Split]([Strings],'|') where idx = 3)
[DomainName] = (Select [Value] From [dbo].[fn_Split]([Strings],'|') where idx = 4),
[SecurityEvents].*
FROM [SecurityEvents]
JOIN [EventsToLog] on [SecurityEvents].[EventID] = [EventsToLog].[EventID]
WHERE [SID] NOT LIKE 'S-%'
Query Output:
quote:
Server: Msg 170, Level 15, State 1, Line 28
Line 28: Incorrect syntax near 'Strings'.
Server: Msg 170, Level 15, State 1, Line 30

Hi,
I have a name field that has fullname in it and i need to parse it to firstname, lastname, middle initial and suffix.
I used the below query to parse the Last Name and first name.
SELECT
SUBSTRING([FullName], 1, CHARINDEX(' ',[FullName]) - 1)AS LastName,
SUBSTRING([FullName], CHARINDEX(' ',[FullName]) + 1, LEN(FullName)) AS FirstName
FROM CustomerTbl
There are middel initials and suffix present in the full name. How do i parse the middle initial and suffix.
The Sample Name that appear in the table:
JONAS VICKY ==> Format without Middle Initial or suffix
MAYES MARY T ==> Format with middle initial
MCGEE, III CLIFTON ==> Format with suffix
Pls advise
Thanks
