Finding A Substring Within A Text
Nov 7, 2007
Hello everyone,
I have 2 identical tables each containing 3 fields (ID, Date, Text). Each table holds news announcements from different publishers using slightly different presentations of identical announcements. I am trying to identify duplicate anouncements.
Example:
Table 1:
ID Date Text
872 3/20/1999 SomeTown, MA -- YYY, Inc., manufacturer and marketer of high-performance, interactivc computer graphics workstations, today announced the 1234 Family of stand-alone workstations. xxx is a registered trademark of yyy
Table 2
ID Date Text
297 3/20/1999 March 3, 1999YYY Inc., manufacturer and marketer of high-performance, interactive computer graphics workstations, Tuesday announced the 1234 Family of stand-alone workstations that allows users to operate in both DEC and IBM computing environments.
Important: The length and contents of the text in red is NOT constant. Only the green substring may appear in both entries (if the two are in fact duplicate anouncements).
I am using SQL Server 2005 Express on Windows XP
Any help/suggestion will be greatly appreciated.

Hi,
According to the docs, when using substring on a text field (not varchar):
substring (<text>, start, length)
...the length in this case, represents BYTEs as opposed to number of characters. So my question is, how many bytes per character (or characters per byte)....or is this a possible conversion?
thanks,

I have Sql server 2005 SP2.
I enabled it for Full Text search. Substring search where i enter *word* doesn't return any row.
I have a table testtable where description has word Extinguisher.
If i run a query with *ting* it doesn't return any row.
select * from testtable where contains(description,'"*xting*"') ;
But it works if i do
select * from testtable where contains(description,'"Exting*"') ;
The Full text search document says it supports substring search.
Is it an issue with sql server 2005?Please help.

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

I have a scenario of where the standard Full-Text search identifies keywords but Semantic Search does not recognize them as keywords. I'm hoping to understand why Semantic Search might not recognize them. The context this is being used in medical terminology and the specific key words I noticed missing right off the bat were medications.
For instance, if I put the following string into a FT indexed table
'J9355 - Trastuzumab (Herceptin)'
AND
'J9355 - Trastuzumab emtansine'
The Semantic Search recognized 'Herceptin' and 'Emtansine' but not 'Trastuzumab'
Nor in
'J8999 - Everolimus (Afinitor)'
It did not recognize 'Afinitor' as a keyword.
In all cases the Base of Full-Text did find those keywords and were identifiable using the dmvsys.dm_fts_index_keywords_by_document.It does show the index as having completed.
why certain words might not be picked up while others would be? Could it be a language/dictionary issue? I am using English and accent insensitive settings?

Hi all,
I have just started using SQL7 and quite dumb at it.
Here is my problem
i have tables ip_address and ip_subnets. both contains more than 20,000 records. Though ideally each subnet should correspond to only one ip address it is not so due to SMS inventory and remote clients configurations etc.
As an example If my ip address is 141.151.128.78 I need to select only 141.151.128.64 ( or atleast 141.151.128.*)as the valid subnet. In other words I need to compare upto 3rd octet and only if it matches with ip address then declare that as the valid subnet.
Pls note that ip addresses vary for each machine though there will 4 octets, I can't use character positions as the nos in each octet might vary from 1-255.
Any help would be greatly appreciated
Pasted here under is the query script I am playing around with charcter poistions which are not working in my favor. Just added to explain my problems in more clearer way
select distinct system_data.name0, System_IP_Address_ARR.ip_addresses0, System_IP_subnets_Arr.ip_subnets0, system_disc.client0 from system_Data, System_IP_Address_ARR, system_ip_subnets_arr, system_disc where system_data.machineid = System_IP_Address_ARR.itemkey and system_data.machineid = system_ip_subnets_arr.itemkey and system_data.machineid = system_disc.itemkey and system_disc.client0 = 1 and substring(System_IP_Address_ARR.ip_addresses0,1,10 ) = substring(System_IP_subnets_ARR.ip_subnets0,1,10) and substring(System_IP_Address_ARR.ip_addresses0,10,1 ) = '.' and System_IP_subnets_ARR.ip_subnets0 not in ('11%.%.%.%','12%.%.%.%', '10%.%.%.%' , '10.%.%.%' , '1.%.%.%') order by System_DATA.name0

I an trying gto devide this one field that contains city state and zip into 3 seperate columns. The Column right now looks like this:
Coulumn1
-------------------------------
SOUTH EL MONTE CA91733617
BOSSIER LA71172
GARDENA CA90249107
MILWAUKEE WI53216
PARIS IL61944
DUQUOIN IL62832
REDWOOD FALLS MN56283
AUBURN ME04210
I tryed this:
use cimpro1
select substring(cust_shipto_addr_l3, 1, 19) as 'City',
substring(cust_shipto_addr_l3, 20, 21) as 'State',
substring (cust_shipto_addr_l3, 22, 31) as 'Zip'
from opcshto
For some reason, when I run the query I get this for State:
State
-------------------------
CA91733617
LA71172
CA90249107
WI53216
IL61944
IL62832
MN56283
ME04210
When I use the substring to only pull characters 20 and 21 it pulls everything startign at 20. I just want it to select character position 20 ans 21 for the state. As far as the substring for City and Zip, everything comes out fine. Its just State that I am having trouble with.
Any help is appreciated.

I'm using the GridView to display some accounting infromation. I have a project where I have a 14 character control number. I would like to have a dropdown list to select the account classification of records to be displayed. The accounting classification is the first two characters of the control number. So the dropdown list needs to show unique first two characters and the GridView will be filtered on these two characters. I have been trying to use "substring" in the ASP.NET code; not even sure you can.
Any suggestions on how to accomplish this would be greatly appreciated. See code below:
<asp:DropDownList ID="DropDownList1" runat="server" AutoPostBack="True" DataSourceID="SqlDataSource2"
DataTextField="control_num" DataValueField="control_num">
</asp:DropDownList><asp:SqlDataSource ID="SqlDataSource2" runat="server" ConnectionString="<%$ ConnectionStrings:GPCRReportsConnectionString %>"
SelectCommand="SELECT DISTINCT [substring(control_num,1,2)] FROM [Request]"></asp:SqlDataSource>
ERROR: Invalid column name 'substring(control_num,1,2)'.

Hi,
I'm trying to do write a query in SQL that returns the last two characters in a field.
If the actual fields are sheep, dog, cat, parrot
I want the query to return ep, og, at, ot
After rooting around I've discovered the SQL 'substring' function.
The problem I have is that the field has a variable length, so I need a way of passing the strign length to substring.
Its probably simple to solve, but not for a rookie like me without an example and I am (as always) grateful for any ideas.

Hi Carmi & Jun,
Thanks for responding. The problem is still persistent. What I want to do is to display two names in a combobox and the box should only be as wide as 2 adjacent names for their actual length. Whether I use char or varchar the combobox is always twice the width defined for the fields. So we will try to find a solution: an elegant one rather than a workaround.
Any new ideas are still welcome.
Thanks again.
Dirk

it's early in the morning (well it is here anyway) and i need a shot of logic...
in the data base i'm currently working with i have a varchar field that holds either a number or a collection of numbers in square brackets. I need to extract the number or the first number in square brackets if it's a list. i know it's gonna be a simple one but my head just won't do it?? i'm trying with substring and charindex to determine the position of the '[' but just not getting it this morning
quick sample of what the data in this column may look like...
declare @t table (col varchar(30))
insert into @t
select '2' union all
select '[5] [4]' union all
select ' [12] [1]'
so i need to get...
col
-------
2
5
12
EDIT-
OK, so i get this to work but only if there is actually square brackets
declare @t table (col varchar(30))
insert into @t
--select '2'union all
select '[5] [4]'union all
select ' [12] [1]'
select col
,substring(col, charindex('[',col)+1, charindex(']',col)-charindex('[',col)-1)
from @t
