Regular Expression?
Mar 25, 2008
Hi
I'm looking to return rows from a table where a column is LIKE a keyword. This is my current code:
SELECT DISTINCT business_name FROM Table WHERE business_name LIKE @keyword + '%' ORDER BY business_name ASC
The problem with this is that if a business is called "The White Ship Inn", and the keyword to match is "White Ship" it will not match. If i put another wild card in front of @keyword then this finds too many matches - i need it to match against columns which either start with the keyword, or have a whitespace in front of them. Is there some kind of T-Sql i can use or will i have to go down the regex route (using this (http://www.codeproject.com/KB/mcpp/xpregex.aspx)) ?
cheers

Does SqlServer support Regular expression?
I want to know if it's avilable or not...
And if it's not available, I want to know any other efficient way to validate string.. manipulating Regular expression style validation.
Thank you all...

I need to remove all the [ and ] in every sql stmt where they are usedto close encircling numeric value, fyi, all these sql stmt areconverted from an Access db. For instance,select *from XYZtblwhere fieldA = [1] or fieldA = [2] or fieldA = [3]to beselect *from XYZtblwhere fieldA = 1 or fieldA = 2 or fieldA = 3-- and of course I'd have written in as follows, but that's not-- the pointselect *from XYZtblwhere fieldA IN (1,2,3)Thanks.

I am try to build a query which only matches whole words and so far I've got this.
Code:
SELECT *
FROM tblSearchWords
WHERE CorrectSpelling LIKE '%[^a-zA-Z0-9]blah[^a-zA-Z0-9]%'
This will return rows which contain the string 'blah' without any numeric or alphanumeric characters beside it. However it doesn't return the rows where 'blah' is either at the start or end of the string as it expects any character except a-zA-Z0-0.
Is there any way to accept string when there is nothing on either side as well?
Thanks,
Goran

Hi,I'm not a big friend of MSSQL, but I have to do one query I've done formySQL.But I don't know how...I have to select 'user' from 'db' where first letter is E or N, second is Bor 0 and after that there are 6 or 7 digits I know.How can I do that?In mySQL it would be something like:SELECT * FROM `table` WHERE `account` regexp '^[EN][B0]123456$' ORDER BY`Id`;Thanks in advance,Martin

I am trying to exclude all strings that has 'a' inside (I havesimplified the actual problem)select 1where 'bb b a dfg' like '%[^a]%'However, the above does not work. By the way, I can not use 'not like'such as:select 1where 'bb b a dfg' not like '%a%'Although the above will work but the idea is that I have to use 'like'and not 'not like'. This is partly because I have to exclude rows froman exclusion table (a table that has many rows that will be excluded).Actually I want to include all srings that has lets say // in it usinga regular expression. I would like to write it as (I am sure it willnot work):select 1where column like '%[^/][^/]%'That should exclude strings like: 'aaa // aa aa' or 'bb bbb // bb' etcand include strings like: 'aaa aa aa' or 'bb aa nn' etcIs there any way to write a regular expression to do it? Otherrwise Ihave to solve this problem without using regular expressions in theexclusion table.Thanks.

Hi
I have a table which stores a big chunk of html text, which I have to search for and replace some strings.
How can I write a query that makes use of regular expressions to do the following:
Below is a block of example text
======================================================================
" src="http://aaaa/bbbb/cccc.nsf/blind%2010x10.gif?OpenImageResource" width=10> <img height=10 alt="" src="http://aaaa/bbbb/cccc.nsf/blind%2010x10.gif?OpenImageResource" width=10><img height=11 alt=""
http://aaaa/bbbb/cccc.nsf/blablablabla?OpenDocument src="http://aaaa/bbbb/cccc.ns http://aaaa/bbbb/cccc.nsf/d8d4f0dfa09ba71142256cc50040ee51/ee9b4493dac727be422571c30027df61? OpenDocument" target=_self>
======================================================================
Now I want to search and replace the string that is highlighted in red with something like "FOUND"
The below string is what I want to search for - I will used PATINDEX on the string below to find the start index of the string in the body, and then I will add on 114 to the when doing a replace:
'%http://aaaa/bbbb/cccc.nsf/%some guid%/%some guid%?OpenDocument%'
For example
REPLACE
(
TheField,
SUBSTRING
(
TheField,
PATINDEX(''%http://aaaa/bbbb/cccc.nsf/%some guid%/%some guid%?OpenDocument%', TheField),
,114
)
,
'FOUND'
)
QUESTION:
what would the regular expression be and how does one type it in the query?
I tried something like the below but it does not work, please advise .....
[a-z][0-9]{32} %/% [a-z][0-9]{32}

I have as csv-file wich I import into an SQL Server table. Now I want to do some checks on it. I use a conditional split to direct data to the other tables (1 table for the correct data, 1 table for the rejected data).
Is it possible to use a regular expression in a case in a conditional split to check if a columns has the right format?
If yes? How do I do that?
If no? What is the alternative?
Thanks!

Thanks in advanace for taking the time to read this post.
I am using MSSQL 2005 and have created a function that allows me to use regular expressions in my SQL queries.
My question is I have a pattern buried in a field of misc data that I need to pull out just that pattern and discard the rest of the data. Here is the Regular Expression I am using
select field1 from table1
where dbo.RegExMatch (field1,'[a-zA-Z]{4}[0-9]{6}[a-zA-Z]{2,4}')=1
This returns all values in the field that match the expression. What I want to do now is remove all data from the field on the left and right of the expression that does not match the expression. How would I accomplish this without reading through the 200k+ records and writing rules for every exception I run across?
so I could have Gar b/a ge 'THE GOOD DATA' m/or1 ba4d da....ta. All I want to do is return 'THE GOOD DATA'

I have created 1 report with 2 datasets. This report is attached to the 1st dataset.For example,1st one is "Smallappliances", 2nd is "Largeappliances".
I created a tablix and, the 1st column extracts Total sales per Sales person between 2 dates from 1st dataset (Small appliances). I used running values expression and it works fine.
Now, I would like to add another column that extracts Total sales per sales person between 2 dates from 2nd dataset (Large appliances). I am aware that I need to use Lookup expression and it is giving me the single sales value rather than the total sales values. So, I wanted to use RunningValue expression within lookup table to get total sales for large appliances.
This is the lookup expression that I added for the 2nd column.
=Lookup(Fields!salesperson.Value,Fields!sales_person.Value,RunningValue(Fields!sales_amount.Value,
sum, " sales_person"),
"Largeappliances").
I get this error when I preview the report.An error occurred during local report processing.The definition of the report is invalid.An unexpected error occurred in report processing.
(processing): (SortExpression ++ m_context.ExpressionType)

Hi, the Microsoft SQL Server version is 2000
Basically I want use a basic regular expression but can't seem to get the syntax right.
i want to compare ID_short = ID_Long
ID_short is a truncated version of ID_Long, and I want to search on the beginning only (hence I can't use the 'LIKE' comparative on it's own).
What is the syntax to use Reg Expressions (or if anyone knows a non RegExp way of searching the beginning please let me know).
Thanks

A developer I need to support believes that the Enterprise Edition is required to take advantage of a dual processor Compaq ProLiant 3000. This machine is not a quad box, just a standard MPS architecture with a single CPU installed.
I recall that the standard SQL 6.5 build will fully utilize a standard MPS DP system and that Enterprise is required only for 4-way, 8-way and n-way boxes such as the Tandems.
Any thoughts?

Hi,
I have a crappy old database that has an email field with a lot of bad data, and I need to use SSIS to extract a list of names & email addresses.
I have an OLE DB Source set up to pull the relevant columns out of the database. Is there a way that I could setup a Regular Expression based filter to disregard any rows where my email Regex does not match the value of the email column?
Thanks,
John

Hi all,
i wrote a little function that is basically supposed to give me a match of a regular expression in C#. i tested it out in VS05 and it seems to work fine. It hits the fan when i try it on SQL Query analyzer once deployed. Anyone have any idea why?
here is the C# class that I deploy to a db using VS05.
using System;
using System.Data;
using System.Data.SqlClient;
using System.Data.SqlTypes;
using Microsoft.SqlServer.Server;
using System.Text.RegularExpressions;
public partial class RegExTest
{
[Microsoft.SqlServer.Server.SqlFunction(IsDeterministic = true, IsPrecise = true)]
public static string RegExMatch(string pattern, string matchString)
{
Regex r1 = new Regex(pattern);
if (r1.Match(matchString.TrimEnd(null)).Success)
{
Regex testReg = new Regex(pattern);
Match regMatch = testReg.Match(matchString);
string runnumber = regMatch.ToString().TrimEnd('_');
runnumber = runnumber.TrimStart('_');
return runnumber;
}
else
{
return null;
}
}
};
Basically i have a teststring that looks like abc_xxx_nnndef. xxx and nn are both numbers, and im using the pattern _\d{3}_ to test it out in SQL (i need the numbers between '_' and '_'). But it never even proceeds past the if statement in SQL i think. here is the basic SQL that i use to test the above function:
use northwind
go
declare @teststring varchar(50),
@pattern varchar(10),
@out varchar(50)
set @teststring = 'dw_012_34.ext'
set @pattern = '_\d{3}_'
set @out = dbo.RegExMatch(@pattern, @teststring )
select @teststring
select @pattern
select @out
Anyone have any suggestions as to why it works in VS 05 when I use it in a C# program, but fails on the SQL version?

HiI have a large table with allot of data in it, Im trying to find the correct SQL statement to select all the records that do not start with a letter or a number.So some records may start with a '~' and a few '$' and even some '?'. So I would like a statement that would select all of these while leaving out any records that start with anything else, such as numbers or letters.And on a similar theme, Im also trying to select all records that start with a number. Ive been using the "select blah from blah where LIKE 'a%'" for each letter and ive tried to have a play and search around that statement....
Today I was told to use a regex within my 'SELECT' statement, but I had never heard of this being done before... so I done a number of searches on Google and although I found references, I didnt actually find any examples. So when I tried to put something together I kept getting errors.
Ive used regular expressions before so theres no problem writing the expression that I need, however Ive no idea how to implement it into a SELECT statement.
If someone could please show me an example of the structure/syntax of an sql select query that contains a regex then I would be most appreciative! :)

I don't like the fact that any user I create has access to system tables inthe Master databases and the ability to issue 'sp_who' plus God knows whatother system stored procs.Is there a white paper or a script to lock down a user so that they do nothave this broad access without breaking their regular ability to run theirown queries against their own databases? I would like them to be a regularuser without the ability to snoop around in my SQL Server.--John Dalberg

Hi-
Someone posted on a thread that you can use VB (or C#) to write Regular Expressions for SQL Server 2005. I know how to write RegEx in VB, so can someone point me to a reference which explains how to use them in / with SQL2005? Or, can someone explain how?
Thanks,

I have transactional replication running. I would like the Snapshot Agent to run regularly (once per day, probably, at 23:00) so that the target data are completely refreshed so that there is little possibility of the target getting out of sync.
The Snapshot Agent's job is kicking off OK, but the "snapshot was not generated because no subscriptions needed initialization". I know I can initialise the subscriptions manually - is there a way to do this so that the initialisation happens just before the snapshot job launches?
Or is this a bad thing to want to do?
TIA
