Text Field Compare

Jun 15, 2004

I am a bit of a SQL Server newbie and have a question. I'm trying to compare two text fields. Both are 56 character fields and are a company name (one company want to see how much customer overlap they have with a newly acquired company). As you can imagine the names are a bit different in each ABN AMRO versus ABN AMRO INC. I tried comparing the first 6, 7, 8 characters with some success. Is there a more advanced way to do this? I appreciate the help.

Compare Date Field To Text Field

Mar 27, 2008

Hi,

I am very new to using SQL. Our department usually uses Brio to query the various databases under our control. However, I have recently come against a problem that prompted me to create a custom SQL query which works well as far as it goes. My problem is looking for specific conditions in billing information I receive monthly. I would like to compare on of the date fields contained in the database with a field in the form of YYYYMM (200710, for October 2007) I have created a custom column generator that forms a date from the YYYYMM. I would like, however, do the translation on the fly and make the comparison during the query. The problem is that query without the date check returns a mass of data, only about 1 percent of which is what I want.

The beginning of the SQL query looks like this:

FROM From.T_Crs_Tran_Dtl WHERE T_Crs_Tran_Dtl.Crs_Bill_Yr_Mo IN ('200710', '200711', '200712') AND ((T_Crs_Tran_Dtl.Crs_Cde IN ('1G', '1V') AND (T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND (T_Crs_Tran_Dtl.Prev_Stats_Cde IN (' ', 'TK', 'TL') AND T_Crs_Tran_Dtl.Cur_Stats_Cde IN ('TK', 'TL') AND T_Crs_Tran_Dtl.Std_Tran_Typ_Cde='B') OR (T_Crs_Tran_Dtl.Prev_Stats_Cde='UN' AND T_Crs_Tran_Dtl.Cur_Stats_Cde='XX' AND€¦

It is the €ś(T_Crs_Tran_Dtl.Dptr_Dte < LastDay(ToDate(Substr ( Crs_Bill_Yr_Mo, 5, 2 )& "/1/"&Substr ( Crs_Bill_Yr_Mo, 1, 4 )))) AND€? part of the query that is just plain wrong. The business part of this statement takes the YYYYMM field and turns it into a date which is the last day of YYYYMM.

I hope someone out there can help me with making this comparison.

I appreciate your help.

Compare Strings In Text Field

Dec 17, 2003

I am trying to build a simple search engine using Sql Server 2000 to scan information about approximatelly 20.000 products.

Heres what I am doing:

I created a table called keywords that contains a reference for each product.

keyword -> varchar(100)
items -> Text

keyword data example:

[keyword] [items]
car 1, 3, 5, 7
blue 3, 5
compact 1,7

I am not using clustered index.

To search basically I run the "AND" or "OR" to select the keywords I want to target.
I need to run another select that would compare the data in the items field depending of the condition selected. If "AND" clause is used I would need to compare all the items that contains the same reference, for example:

looking for car compact using "AND" clause
result = 1

looking for car compact using "OR" clause
result = 1,3,5,7


There is no table that holds references. The items are stored in a text field in the keyword table. I can compare data using script like AsP spliting the items by comma or space, but that can be too slow and use up a lot of RAM. Another solution would be to use a table to hold the references but that would affect performance dramatically because of the large number of records created and storage space used. One example, if I have 60.000 keywords and each keyword has an avereage of 200 references, I would have to generate 12 milion records.

I want to know if there is a function or routine in SQL server to compare matched references on the fly in the server between two or more fields and how should I do it.

In addition, in this scenario, how should a clustered index help?


Thanks

Rodrigo

Problem With Text Field: Text Input Too Long, Weird Characters

May 15, 2006

Hi,

Im a programmer for an university webportal which uses php and msssql.
When an user creates a new entry and his text is too long the entry is cut short and weird characters appear at the end of the entry.

For example:
http://www.ttz.uni-magdeburg.de/scripts/test-messedb/php/index.php?option=show_presse&funktion=presse_show_mitteilung&id=333

How can I set the text limit to unlimited?
Could it be something else?
Is there a way of splitting an entry to several text fields automatically?


Thanks in advance for any help you can give me,
Chris

SQL 2012 :: Text Qualifier Inside A Text Qualified Field

Mar 12, 2015

In SQL 2005 if i was trying to insert some data with a text qualifier inside a text qualified field, it would work, for example:

"Name","ID ","Location","","Comany",""House Name" Road",

In SQL 2012, this fails with the error message, cannot find the text qualifer for field.

To get around this, we are having to import the data into a Dirty Data column of aTEMP table, ID, Dirty Data, Clean data - perform multiple updates and change the text qualifier and ensure they are only changed in the right places so we can keep the ". In this example, we changed the text qualifier to PIPES.

After these updates, we then export the data from CLEAN data back out to CSV, then reimport it into the origional destination table with a new text qualifer.

Access Memo Field To SQL Server Text Field

Nov 19, 2006

Hi,

I'm importing an Access database to SQL Server 2000.
The issue I ran into is pretty frustrating... All Memo fields that get copied over (as Text fields) appear to be fine and visible in SQL Server Enterprise Manager... except when I display them on the web via ASP - everything is blank (no content at all).

I didn't have that problem with Access, so I ruled out the possibility that there's something wrong with the original data.

Is this some sort of an encoding problem that arose during database import?
I would appreciate any pointers.

Create Date Field From Substring Of Text Field

Jul 20, 2005

I am trying to populate a field in a SQL table based on the valuesreturned from using substring on a text field.Example:Field Name = RecNumField Value = 024071023The 7th and 8th character of this number is the year. I am able toget those digits by saying substring(recnum,7,2) and I get '02'. Nowwhat I need to do is determine if this is >= 50 then concatenate a'19' to the front of it or if it is less that '50' concatenate a '20'.This particular example should return '2002'. Then I want to take theresult of this and populate a field called TaxYear.Any help would be greatly apprecaietd.Mark

MS Access Memo Field To SQL Server Text Field

Aug 20, 2006

Hi all,



i've a reasonable amount of experience with MS Access and less
experience with SQL Server. I've just written an .NET application that
uses an SQL Server database. I need to collate lots of data from around
the company in the simplest way, that can then be loaded into the SQL
Server database.



I decided to collect the info in Excel because that's what most people
know best and is the quickest to use. The idea being i could just copy
and paste the records directly into the SQL Server database table (in
the same format) using the SQL Server Management Studio, for
example.



Trouble is, i have a problem with line feed characters. If an Excel
cell contains a chunk of text with line breaks (Chr(10) or Chr(13))
then the copy'n'paste doesn't work - only the text up to the first line
break is pasted into the SQL Server database cell. The rest is not
pasted for some reason.



I've tried with MS Access too, copying and pasting the contents of a
memo field into SQL Server database, but with exactly the same problem.
I've tried with 'text' or 'varchar' SQL Server database field formats.



Since i've no experience of using different types of databases
interacting together, can someone suggest the simplest way of
transferring the data without getting this problem with the line feeds?
I don't want to spend hours writing scripts/programs when it's just
this linefeed problem that is preventing the whole lot just being
cut'n'pasted in 5 seconds!



cheers

Dominic

How Can I Parse Text Held In MS SQL 2005 Text Field

Apr 24, 2007

Hi,I been reading various web pages trying to figure out how I can extract some simple information from the XML below, but at present I cannot understand it.
I have a MS SQL 2005 database with which contains a field of type text (external database so field type cannot be changed to XML)The text field in the database is similar to the one below but I have simplified it by remove many of the unneeded tags in the <before> and <after> blocks. I also reformatted it to show the structure (original had no spaces or returns)
For each text field in the SQL table contain the XML I need to know the OldVal and the NewVal.
<ProductMergeAudit> <before>  <table name="table1" description="Test Desc">   <product id="OldVal">  </table> </before> <after>  <table name="table1" description="Test Desc">   <product id="NewVal">  </table> </after></ProductMergeAudit>

Adding Text To A TEXT Field (MS-SQL2000)

May 9, 2007

Hi everyone,

I'm extremely new to SQL so be nice

I am attempting to write a script to add onto the end of a text field the words " -- Disposed " (About 60 rows worth).
The field is a TEXT field, so unlike a varchar field I can't just use Update as shown below.


Code:

Update AR_Primary_asset
Set AR_Primary_asset.description = AR_Primary_asset.description + ' -- Disposed'
Where AR_Primary_Asset.ASSET_REF in ('1','2','4')



I found on the Mircosoft pages about UPDATETEXT, but this only seem to work to update one row (In the case below Asset_ref = 3, was the only row effected) .


Code:

DECLARE @Dispose binary(16)
SELECT @Dispose = TEXTPTR(DESCRIPTION)
FROM AR_PRIMARY_ASSET
WHERE AR_Primary_Asset.ASSET_REF in ('1','2','3')

UPDATETEXT AR_PRIMARY_ASSET.DESCRIPTION @ptrval null null ' -- Disposed'



So i wrapped it into a cursor, this worked on my test SQL server which runs SQL2005.


Code:

DECLARE @Dispose varbinary(16)

DECLARE cursor1 CURSOR FOR
SELECT TEXTPTR(DESCRIPTION)
FROM AR_Primary_Asset
Where AR_Primary_Asset.ASSET_REF in('1','2','3')

OPEN cursor1

FETCH NEXT FROM cursor1
INTO @Dispose

WHILE @@FETCH_STATUS = 0
BEGIN

UPDATETEXT AR_Primary_Asset.DESCRIPTION @Dispose NULL NULL ' -- Disposed'

FETCH NEXT FROM cursor1
INTO @Dispose
END

CLOSE cursor1
DEALLOCATE cursor1



But when it was run on our SQL2000 server it gave the following error message

Quote: Msg 403, Level 16, State 1, Line 1

Invalid operator for data type. Operator equals add, type equals text.

I've never used vars, cursors, updatetext or even text fields before. So maybe I am going about it totally the wrong way.

Is anyone able to tell me a better way to write this? or how to make it compatible to SQL2000?

Should I Use Text Field Or Binary Field ?

Jun 1, 2008

Application is ocr'ing tiff image files and then storing the resultant text data in a text field in SQL 2005 database. This field is then used with the full text catalog.

All works fine,

However, am I using the correct field type to store the text files for efficiency and space saving?

If I use a binary field, does this reduce the size of the database by compressing the text data in the binary field? Also, is there a limit as to the size of text file that I could store in a binary field?

It would be good to get feedback on this before I go too far down the wrong road.

So, text field to store the text data or binary field to store the actual text file?

How To Update Text Field

Sep 8, 2004

Hi all,

I have a table with millions of records, table has three fields: case_id,line_no and notedata field, notedata field is 60 chars long, datatype varchar.for each case_id there could be as many as 2000 line_no meaning 2000 notes. I need to compress these notes into one note by case_no, For example case_no 1 could have 2000 lines of notes but my comressed table shoul have only one line containing all 2000 notes in line_no sequence.

my compressed table contains two fields case_no and notetext, notetext is a text field.

Replication - TEXT Field

Dec 30, 1998

I have a table that has a TEXT field and I want to replicate it. It already has a primary key field in it. I read that in SQL Server 6.5, you can do transactional replication on a table that has a TEXT field in it. I'm wondering if I need to do any other special configuration to replicate this table, i.e. enable the truncate on checkpoint option or anything else? Thanks, Hoang
