T-SQL (SS2K8) :: How To Parse A String To Equal Length Sub-strings

How to parse a string to equal length substrings in SQL

I am getting a long concatenated string from a query (CTVALUE1) and have to use the string in where clause by parsing every 6 characters..

CREATE TABLE [dbo].[PTEMP](
[ID] [char](10) NULL,
[name] [char](10) NULL,
[CTVALUE1] [char](80) NULL
)
INSERT INTO PTEMP
VALUES('11','ABC','0000010T00010L0001000T010C0001')
select * from ptemp

after parsing I have to use these values in a where clause like this

IN('000001','0T0001','0L0001','000T01','0C0001')

Now ,the values can change I mean the string may give 5 values(6 character) today and 10 tomorrow..So the parsing should be dynamic.

Parse And Format Name Strings.

Please let me know if you come across any name strings this function cannot parse.
CREATE function FormatName(@NameString varchar(100), @NameFormat varchar(20))

Parse XML Strings In SQL Text Field

Jul 23, 2005

I am trying to build a query on a SQL2000 text field which contains XMLstring. The query is like "select requestnumber from history whererequestnumber is like '%re1%'". As you can see in the following samplerecords, the xml string has database structure and the requestnumber isa node of the XML. I wonder if it is possible to have SQL server parsethis field and allow me to do the query. If not, any suggestion wouldbe appreciated as to how to store XML data in SQL2000. I am not sureif I misused the SQL2000 XML feature correctly. So far I pass the rawquery result to ADO and manipulate it in XMLDOM.The table is to capture history of changes in any record in mydatabase. So I need to keep it simple so any record from any table canbe stored in here. The structure of the table is like this:sysObjectNumber(int, not null)recordKeyValues(char(30), not null)archiveTime(datetime, not null)history(text, null)A sample record would be like the following:sysObjectNumber recordKeyValues arvhiveTime History=============== =============== =========== =======1728725211 ABC 2005-03-25 8:09:56.700<history><partnumber>ABC</partnumber><type>2140461537</type><color>1</color><remain></remain><lastdatein></lastdatein><lastdateout></lastdateout><lastquantityin></lastquantityin><lastquantityout></lastquantityout><threshhold>null</threshhold><usedby>user1</usedby></history>1728725211 ABC 2005-03-28 11:01:14.407<history><partnumber>ABC</partnumber><type>2140461537</type><color>1</color><remain></remain><lastdatein></lastdatein><lastdateout></lastdateout><lastquantityin></lastquantityin><lastquantityout></lastquantityout><threshhold>4</threshhold><usedby>user2</usedby></history>1728725211 ABC 2005-03-28 11:46:12.723<history><partnumber>ABC</partnumber><type>2140461537</type><color>1</color><remain>4</remain><lastdatein></lastdatein><lastdateout></lastdateout><lastquantityin></lastquantityin><lastquantityout></lastquantityout><threshhold>4</threshhold><usedby>user1</usedby></history>1728725211 ABC 2005-03-28 11:46:35.273<history><partnumber>ABC</partnumber><type>2140461537</type><color>1</color><remain>4</remain><lastdatein></lastdatein><lastdateout></lastdateout><lastquantityin></lastquantityin><lastquantityout></lastquantityout><threshhold>4</threshhold><usedby>user4</usedby></history>

T-SQL (SS2K8) :: Joining Where Values Do Not Equal One Another

Apr 23, 2014

I have two select statements; one for open purchase orders, one for open customer orders. I would like to be able to combine the query based on i.item in the top statement joined with c.item from the bottom statement. The i.item is related to a specific c.item, but they do not have the same values. In this case I want to join based on.

p.item=i.item where
1001099548=1001099550
84162359=84198545
84532300=84532293

305545A3=87433653
87444977=87444975

left side coming from p.item = right side coming from c.item.

Here are my statements.

--#1 OPEN PO's
SELECT p.item
,(p.qty_ordered-p.qty_received) as POQtyRemaining
,i.item

Zero Length Strings Showing Up As A Space In Views Linked In Access

Jun 28, 2000

Zero Length Strings Showing up as a Space in Views linked in Access

I have code being converted from a SQL 6.5 DB to SQL 7; SQL 7 does not concantenate NULLS like in 6.5, so i have replaced all occurances of concantenated NULLs with zero-length strings (''s); in SQL, the view displays the zero-length strings properly, but when i view the linked view in Access97, the zero-length strings are displayed as spaces; is this a SQL problem or an Access Problem? Is there a solution?

Example of display:
10132 Hampton, VA: A. Deepak Publishing

SELECT PublisherID, Info = CASE WHEN City IS NOT NULL
THEN City + CASE WHEN State IS NOT NULL
THEN ', ' + State ELSE '' END + ': ' ELSE ''
END + Publisher
FROM tblLibraryPublishers

When view is linked in Access97, the display will be:
10132 Hampton, VA : A. Deepak Publishing
(this spacing can produce a number of lookup/search problems if only the Publisher name is displayed because a space is added to the beginning of the Publisher name)

Thank you!

T-SQL (SS2K8) :: Function To Parse Each Command In The Table

Nov 19, 2014

I am debugging a DB maintance script which creates a table of index maintainance commands which are created separately for each index according to the level of fragmentation and other factors.

For the debugging process, I'm looking for a way to parse each command in the table without actually running them to locate any syntax errors. In other words, as if you clicked the blue check on each one.

Does such a function exist in SQL 2008 (the version I'm doing this on) or other versions?

Parse A String Using Charindex

Jan 15, 2008

Hi,

I've the following query. I'm using the yellow highlighted to join 2 tables, as these tables dont have a relationship between them.
The format of the name field is 'AAAA-BBBBBB-123'
here A will be only 4 chars, followed by '-' B can be any number of chars again followed by '-' and the last is the id which I'm using to do a join. This query will fail if the id is just 1 digit as its taking the last 3 chars as the id.
I dont know how to get the id from the right using charindex. Charindex would search for the first occurence of '-' from the right and get the chars after hypen i.e 123. How can this be achieved?

SELECT id AS 'ID',
name AS 'name',
sequence AS 'num'
FROM
FirstTable A
INNER JOIN SecondTable q
ON (CONVERT(INT,RIGHT(name,3))= a.id)
INNER JOIN ThridTable t
ON(t.id = q.id)
INNER JOIN FourthTable s
ON (q.name = s.name )
WHERE A.id = @ID
AND t.name=LEFT(s.name,((CHARINDEX('-',s.name))-1))
ORDER BY 'ID','num'

One more question on this is: Is this a good way of joining tables? If I dont use this I've a very large query containing unions. Which one should be bug-free and more efficient?

Thanks,
Subha

Nested CASE To Parse A String

Feb 6, 2006

I am attempting to create a view to bring together multiple joined tables based ona one to many relationship

Eg Table1 contains code, address
Table2 contains code, financial details
table3 contains code, financial history

This view is then going to be used to update a table with only one record for each 'code'. i.e. NewTable = code, add1, add2, city, prov, postal, financialvalue, history value1, history value2

My current stumbling block is:

One of the fields in table1 is a free format address field (address).
eg. could be (street addres, city prov, postal)
or
could be (street address 1, address2, address 3, city prov, postal)

I want to be able to assign individual components of the address to corresponding fields

if # of commas = 2 then
address1 = substring(address,1, position of first comma)
cityprov = substring(address,possition of first comma, position of second comman)
postal = substring(address rest of field)

I have a UDF which returns the number of commas but I cannot figure out how to use either a nested case statement to parse the string...

ANy ideas on how best to accompish this?
( this table is needed for some leacy software which can only handle one record with all infor....

Parse Long String To Columns

Dec 31, 2007

I have a column with varchar(2000) that contains events with time-stamps. The data looks something like this for a record:

03:14:46: abc 03:14:47: def 03:14:59: xyz 03:15:17: zzz

I would like to parse out each time-stamp and event to a separate columns, like

col1= 03:14:46: abc
col2= 03:14:47: def
col3= 03:14:59: xyz
col4= 03:15:17: zzz

The number of events are dynamic so number of time-stamps with events can be anything from 2-30 of them.

Anyone would suggest how I can resolve this?

Thanks.

How to parse a string to equal length substrings in SQL

I am getting a long concatenated string from a query (CTVALUE1) and have to use the string in where clause by parsing every 6 characters..

CREATE TABLE [dbo].[PTEMP](

Now ,the values can change I mean the string may give 5 values(6 character) today and 10 tomorrow.. So the parsing should be dynamic.

Can You Parse Out A Text String &> 8000 Chars Long??

Mar 30, 2005

Any way to parse out a text value (not varChar, using text data type) that is > than 8000 characters long? I'm looping through 1 big string passed to the DB that is pipe delimited, but I find myself needing the substring function to keep track of which segment I'm acting on (after an update, I then need to take that segment and remove it from the string)...but the subString function won't take anything larger than 8000 chars.

Say I have this string that is text data type...

'aaa|bbb|ccc|ddd|....'

..and so on, surpassing 8000 char length, how could you parse it out using the pipes as the delimter, then do an Update using that segment? Afterward, return to that string and find the next segment, then use it, and so on (in a loop). I tried using an update to set the string = replace(string, segmentJustUsed, '') to "erase" it, but replace can't take text as the datatype. Any help? Hope this isn't to confusing.

Stored Procedure To Parse Delimited String To Table?

Apr 10, 2015

SP to parse a delimited string and insert the result in a table. I am using SQL Server 2008 R2. I have 2 tables - RawData & WIP. I have Robots on a manufacturing line capable of moving data to a DB.

How To Show Two Dataset With Equal && Non Equal Of Multiple Selection.

Jun 14, 2006

Dear Friends,

In my report, I am having Listbox for users to choose Country, City & Company.
The user can choose Country. Based on the country selection, cities will be listed out.
Based on the city selection, Companies will be listed out.
They can choose companies.

Now, I have to show two set of results.

A. List of Companies as per selection ( dataset with equal to selection )

B. List of Companies which are not selected ( ie dataset with not equal to selection )

I have created a dataset with all companies and filter it by selection. When I tried with the filter option in the Dataset, I am able to check for only one value and not for multiple value. If the selection is one company, then I can filter it. But if they choose 5 companies, I am not not able to filter it. Is there any other option I can try out.

Please advice. Thanks.

warm regards

SQL Server 2008 :: Using Left And Charindex To Parse String / Getting Rid Of Rest Of Data

Jun 16, 2015

I am trying to erase some erroneous bad data in my table. The description column has a lot of </div>oqwiroiweuru</a> weird data attached to it, i want to keep the data to the left of where the </div> erroneous data begins

update MyTable
set Description = LEFT(Description(CHARINDEX('<',Description)-1)) where myid = 1

that totally works.

update MyTable
set Description = LEFT(Description(CHARINDEX('<',Description)-1)) where myid >= 2

gives me a Invalid length parameter passed to the LEFT or SUBSTRING function. The statement has been terminated error.

SQL Ce 3.5 && DataSet -&&> String Length??

Oct 10, 2007

Hi!

I create a dataset from a sqlce 3.5 database (I drag-dropped the tables of the database on the DataSet).

And when I try to put a text with more than 4000 characters in the dataset, it throw me an exception ....

--> I tried to insert this text directly in sql ce and it works well! So I think that the DataSet has a limitation?? But the maxlength of the string coloumn of the dataset is set to 536870911

Do you have an idea about this problem?

thx for help and sorry for my bad english

Updating The String Removing The Strings.

May 20, 2008

I have to write a query to update the table to remove dots .... from the string value.
so i could write.

UPDATE tbaddress
SET Title='New address'
WHERE Title='New address....'

but, there could be more than this specific record in the table, so i have to find each single record to do this. Is there a way to update the table so I can just remove the .... but rest of the text remain.

thanks
