SQL Select Statement With Regular Expressions
Apr 27, 2007
Hi
I 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! :)

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

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?

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,

Hi,I trying to write a select statement that will return each of my salesmen a region code based on a table of post codes using wildcards... eg.MK1 1AA would be matched in the region code table to MK1%SELECT dn.DEALER_CODE, dn.NAME AS DNAME, rc.REGION_ID,rc.POST_CODE, dn.POSTAL_CODEFROM REGIONAL_CODES rc CROSS JOINDEALER_NAW dnWHERE (dn.POSTAL_CODE LIKE rc.POST_CODE)The above statement works BUT there are some post code areas such asour friends in Milton Keynes that are split into two regions... eg MK1is region id 2 and MK10 is region 3.So a dealer with post code MK10 1AA would be matched to both rowsreturning duplicatesPOST_CODE REGION_IDMK1% 2MK10% 3I think the answer would lie in a subquery which returns the ID of theregion with the longest length of the postcode match (e.g.len(POST_CODE) for the rc table... return only the MAX....any ideas????Any help muchos appreciated, and I apologies now for the naming of thedealers name as a reserve word... not me!Ct

Hello,
Lets say I have a SP that return 1000 records,
do I get any better speed if doing it on a SP instead of just SELECT without an SP ?
if I have many users on a web-site that will execute this SP - will they get any better
speed because it is a SP ? - can SP cache itself - if so - for how long ?
(Why should I use SP if not passing any parameters ?)

Little complex but I'll try to explain the best I canI have the following table…
UserID___Year___Month_____A1____A2____B1____B2
__1_______4______5______45_____5____43____0
__1_______4______6______10_____12___1_____3
__1_______5______5______12_____22___8_____7
__1_______5______6______11_____10___5_____0
__2_______4______5______9______65___33____66
__2_______4______6______3______3____10____11
__2_______5______5______44_____2___77_____1
I want to pull out the data to show the sum of the totals for each year the user is in. The idea is to then be able to see a comparison for year on year on a month by month basis
Eg.
UserID____TotalAYear4____TotalBYear4___TotalAYear5____TotalBYear5___Month
__1___________50_____________43___________34____________15__________5
__1___________22_____________4____________21____________5___________6
__2___________74_____________99___________21____________5___________5
There would be no data returned for UserID2 for month 6 as there is no data for them for year 5 month 6 therefore no comparison can be made.
I’ve having real difficulty getting the correct SQL syntax to do this. Any ideas or pointers would be great thanks

Hi,
Is there any way to group variables present in a select statement.
My code:
SELECT @var1=something, @var2=something_else
FROM ...
GROUP BY @var1
I wanted to group by 'something' hence I used a variable to assign it to. But I'm unable to group it.
Any thoughts?
Thanks,

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

ORDER BY Field01
The results are just as I need:

Because other reasons. I need to modify that query to:
Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:
Field02

And what I need is (without showing any other field):
Field02
----------------------
8461760
22810
Is there any good suggestion?

I am using three tables in this query, one is events_detail, one is events_summary, the third if gifts. The original select statement counted the number of ids (event_details.id_number) that appear per event_name (event_summary.event_name).
Now, I would like to add in another column that counts the number of IDs that gave a gift who attended an event that were also listed in the event_ details table. So far I have come up with the following. My main issue is linking the subquery properly back to the main query. how to count in the sub-query and have the result placed within the groups results in the main query.
SELECT es.event_name, es.event_id, COUNT(ed.id_number) Number_Attendees,
(
SELECT COUNT(gifts.donor_id) AS Count2
FROM gifts
WHERE gifts.donor_id = ed.id_number
) subquery2

Hi All,
Can some one point me in the right direction in how to construct my SQL query within my cursor?
I Have got a cursor which i am using to iterate through a table, What i am trying to do is in my statement(used to open the cursor) is compare 2 tables (the one which my cursor is iterating) to see if there is a matching row in the other table (using both tables ID's Like So:
SELECT column_List
FROM Table1
WHERE Table1_id = Table2_id
so for each row my cursor checks if there is a corresponding match in table2... but i would like to write to an error log
and do other statements if there is no match
how do i add this condition to my statement either using an if...else statement proceeding to the next row?
here is the statment i attempted to write:
SELECT column_List
FROM table1
WHERE
Table1_id = Table2.id
now i want to incoporate the statements below into the statement above as a condition when table1.id <> table2.id
IF table1.id <> table2.id
BEGIN
SET @DebugMessage = 'data not live.'
RAISERROR (@DebugMessage, 16, 1) WITH LOG
END
essentially what i am trying to sayin my statement is:
go to the first row
check if it has a match in table 2,
if there is no match execute a number of statements such as error loging e.t.c
go to the next row
repeat the previous statements
...i also looked through some Case...When statements am just not sure how to put in the condition
thanks in advance
