Hi All,
I have the following scenario. I have a table called Invoice. This
has around 30 columns of which i have to do a retrieval based on
filter conditions on 10 columns. These filters need to be partial
searches i.e. for e.g the Customer name could be 'Arun', 'Parthiv',
'Aaron', now i should be able to search the customer as 'ar' and it
should return 'Arun' and 'Parthiv'. My concern is there are 10 columns
on which this like '%x%' search has to be done and there will
practically be hudreds of thousands of rows. can anybody suggest me to
improve the performance of such a query. Currently what i am thinkin
of is
select Id, Memo, .. FROM Invoice where CustomerName like '%' + @Name +
'%' and etc.
P.S. am using ASP.Net as the front end.
For those implementing encrypted columns, what is the recommended approach when allowing users to also do partial searches on encrypted data? (ie email or creditcard info where the tables contain millions of rows). I understand one cannot have the encryption without performance impact, but the searches can be 10 to 20 times as long as when the info is stored in normal char(20) columns. Just looking as a way to try and lessen the impact.
I was doing research oh how to do some searches on dates that allow a bit of a freedom to the person searching. They should be able to specify the parameters. For example how would you make a search for all events that happened on a specific day in any year,any month? example : every 18 Or how would you searh for values that happened in a specific month in any year and any day? eg. May Or how would you search for values that happen in a specific year and any day and month? eg. 2007 Or how would you search for values that happen every 18 May?
I tried few things and can only work out the search for the year bit. The values are saved in the database as DateTime.
First thank you for all your help thus far. Now I'm stuck again. I've been doing a lot of reading on triggers and logging information into tables but I've been trying to capture how many times someone enters an item into the search box.
So every time somebody types Gumballs into the search box I want to capture it and the name of the person who is currently logged in. Is there away to do this? Maybe this is something that I should be checking in ASP.NET forums?
I have a number of functions that require the input of parameters in order to ultimatly create a report under Reporting Services by making use of a Stored Procedure.
All the functions etc work as does the stored procedure, but it only works if I specify data that I know exists e.g.
Hi Everyone. I have created a procedure on sql to obtain information about two tables ( bookinfo and author). The procedure is :
CREATE PROCEDURE FindBookByAuthor @Aname char AS
select b.libcode, b.title, b.subject, a.authorname, b.instock from bookinfo b join authorinfo a on b.authorid = a.authorid where a.authorname like '%' + @aname + '%' GO
I have tested this procedure changing the variable @aname for the surname of the author. This works fine. The problem comes when I execute this procedure from web matrix. I use a textbox to obtain the data for the variable @aname. I send the data. What happens is that when I run the web page and look for a book through the author the select statement behaves differently and gives me a different output.
Hi, I am looking for an easy and efficiant way to add a boolean search function to an already existing search i have using ASP pages and MSSQL 2000 SPROCS.
Currently I have some code such as:
CREATE PROCEDURE sp_name
@var1 int = NULL, @var2 varchar(50) = NULL
AS
SELECT blah, blah, blah FROM sometable INNER JOIN anothertable ON anID = anID WHERE (table1.column2 = COALESCE(@var1,table1.column2) AND table2.column4 = COALESCE(@var2,table2.column4))
and this works like a charm, if i pass a value into @var1 or @var 2 it gives back results where those crietera match, or if I pass no values in it returns all records.... anyways, you get the idea...
Now I would like to add the ability to introduce a 3rd variable, and have it run a boolean search on a varchar(2500) column. This column is a description field for an image so I would like to be able to search the descriptions by passing in something like 'car OR bike AND travel' and return all the records that have the words 'car' or 'bike' and 'travel' somewhere in the description field.
How can i do this? I am using SQL Server Standard Edition so I don't believe I have full text search functions available, (not sure if that would even help).
Thanks all for your support and guidance!
P.S. i would also like to maintain the functinality so that if all the @var# are blank it still returns all records.
I am writing a stored procedure to pull records from a table of personal data related to jobs applied for.
There are 3 tables involved, the jobs, the applicants and the applications.
I need to search on job title, job ref from the jobs table and on forename, surname and applicant ID from the applicants table.
There are some quirks here, if the user enters an applicant ID then we can simply scan the jobs table for that id where it also matches the job title wildcards, so that is quite easy to manage.
My own idea for the more complicated searches was to gather the unique ID's from the jobs table into a var, then do similar with the applicants and then search the applications table where both these ID's matched? I think that wouldn't work so well if using the 'WHERE IN()' clause for the main query?
So what approach would be best here to perform the second part of the SP if the client hasn't passed an ApplicantID?
Obviously the applications table has both JobID and ClientID's to relate back to the applicants table.
So can anyone help here, it seems a fairly complicated statement or set of statements would be required here.
Here is my requirement: The script needs to enumerate the the databases in a givin instance of sql server. Then it needs to output the account with permissions on that server. Finally it then needs to search stored procedured for reference to specific file and account names loaded from a csv file. The results should be output to a text file or displayed in an exportable window format.
What I don t understand: What do they mean by: account with permissions on that server, which account re they talking about
and what do they mean by the SP references a specific file and account name? how can an SP reference a file or account name. i have never seen that? Thanks for help.
For anybody that implemented fuzzy searches in SQL Server or any otherdatabase for that matter. I have implemented edit distance algorithm,specifically q-grams, in SQL Server and wanted to get some opinionsfrom anyone who used a similar algorithm in a DBMS.We are looking to implement fuzzy address search and are employingnumber of different techniques including synonyms for strings like"drive", "dr", "drv", etc... Number expansion, so 6 ave = Six Ave =6th Ave = 6... Now, we also have an implementation of edit distancealgorithm, which would cover misspellings and similar sounding words.One of the challenges is putting various techniques together. Synonymsand number expansion techniques go well together but no edit distance.Also, I am trying to figure out how to leverage edit distanceimplementation for 'contains' searches. So if a string like'Mississippi Municipal Building' would be returned if the Search is for'Misisipi Municipal'.Any thoughts?
I have a database containing several tables with many different fields. I need to create an admin section that lets me search on one field or the combination of several. Does anyone have links to pages that offer a general overview for inhouse database search strategy and admin edits. Thank you
I have recently become responsible for a small database for a volunteer soccer league. I am reasonably savvy when it comes to development, but I have not had a lot of experience with administration before.
I need to do what I think must be pretty simple: set up full text indexing so I can use a CONTAINS search on a table. The table contains all of the fields the kids use, and each field has a number of divisions that typically play on that field; we use these 'favored divisions' to make scheduling a little easier. Now, one day when I have time, I will set up a proper, normalized, one-to-many relationship between the favored divisions and the playing fields, but right now it's basically like this:
fieldID (int, primary key, identity seed) fieldName (varchar), e.g. High School Field favored_divisions (varchar) - comma-delimited list of divisions, e.g. G10,B14,G12
I imagine it's probably database sacrilege to have a comma-delimited list like that, but we don't have the resources now to re-write that piece of the web application. My question is, in SQL Server 2005, what do I need to do to be able to do a full-text search on this field with the following query:
SELECT fieldID, fieldName FROM playing_fields WHERE CONTAINS(favored_divisions,'G10')
Right now the query runs and does not return an error, but does not return any results, either. IIRC, full-text indexing is enabled by default in SQL Server 2005, but I am not familiar with the procedure -- something about having to populate a catalog. Do I need to edit or set up a new index on the actual playing_fields table? What has to happen to make this work?
I have a form that loads a dataset. This dataset is composed from SQL statements using alias and unions. Basically it takes uses data from 3 tables. This dataset also has a alias column called ClientName that consists of either people's name or business name.In addition, the form also consist of a search field that allows user to enter the 'ClientName' to be searched (i.e. to search the alias column). So, my question is how can the alias column be searched (user can also enter % in the search field)Function QueryByService(ByVal searchClientNameText As String) As System.Data.DataSet If InStr(Trim(searchClientNameText), "%")>0 Then searchStatement = "WHERE ClientName LIKE '" & searchClientNameText & "'"Else searchStatement = "WHERE ClientName = @searchClientNameText"End If Dim queryString As String = "SELECT RTrim([People].[Given_Name])"& _"+ ' ' + RTrim([People].[Family_Name]) AS ClientName, [Event].[NumEvents],"& _"[Event].[Event_Ref]"& _"FROM [Event] INNER JOIN [People] ON [Event].[APP_Person_ID] = [People].[APP_Person_ID]"& _searchStatement + " "& _"UNION SELECT [Bus].[Organisation_Name],"& _"[Event].[NumEvents], [Event].[Event_Ref]"& _"FROM [Bus] INNER JOIN [Event] ON [Bus].[APP_Organisation_ID] = [Event].[APP_Organisation_ID] "& _searchStatement ..........End Function
i want to be able to do full text searches on a table that i have that already has data in it.. i created a new catalog, then started incremenetal population.. but nothing happened? will it only catalog the new data thats been entered into the table after i start incremental update? so since i have data in teh table already, would i need to do a full population first before i start incremenetal population?
The reason it is poorly designed is the table is used to hold questions and answers, all with a 1:1 relationship. Instead of having ID, ProductType, Question, Answer they have unfortunately adopted the approach of the above i.e:
id 1 thisID 3 parentid nuLL DESCRIPTION: this is a question
id 20 thisID 3_1 parentID 3 DESCRIPTION: this is the answer to the question above
So I am writing a sproc that does this using a temp table. I got this far:
SET ANSI_NULLS ON GO SET QUOTED_IDENTIFIER ON GO -- ============================================= -- Author:Spencer -- ============================================= ALTER PROCEDURE [dbo].[GetFAQs] -- Add the parameters for the stored procedure here @ProductType varchar(255) AS BEGIN SET NOCOUNT ON; -- Insert statements for procedure here CREATE TABLE TEMP ( IDINT, thisIDvarchar(50) null, parentIDvarchar(50) null, Titlevarchar(255) null, DescriptionQvarchar(8000) null, DescriptionAvarchar(8000) null, ProductTypevarchar(255) null, )
SELECT ID, thisID, parentID, Title, DescriptionQ, DescriptionA, ProductType FROM A2Z WHERE ProductType = @ProductType AND parentID IS NULL END GO
This gets all my questions for that product type.
What I need to do is load the questions into my temp table and then run through the a2z table again gaining the answers to the questions (the parentid holds the question ID). The answers then will also get loaded into the temp table.
I'm an SQL novice, but I know this must be a common problem.
I'm trying to select a recordset (using ASP), but I know I only want part of the recordset, and am not sure how to limit it ahead of time.
For example, the query will return about 500 rows, but I know I only want to use a small section of these records. I want to give the user the ability to navigate through small sections of these 500 rows without having to get all rows all the time. I know ahead of time which rows to get, but have no idea how to limit the recordset before I get it (there is no fields in the database to help).
This is what I'm doing now. "select * from xyz where id=xxx order by date desc;" I know I only want the first 10, or 10-20, or 400-410. The way I'm doing it now, I'm getting the whole recordset each time, doing a "rs.move x" where x is where I want to start. This is really a waste of network traffic and memory since my SQL server is on a different machine as the web server running ASP.
How do I do this?
Please email me if you could at pmt@vantagenet.com
Hello - I was wondering if anyone knew how to do this -
I have a database with a field for Id, LName, GName, DOB. In the LName field, some of the names have * placed after the names. Is there a way I can search for the entries in LName with the * in the record?
I have started a project using Linq for sql and SSCE. Everything goes well until I realize that SSCE can only run in full trust. Linq for sql is planned to support partial trust scenario. Any plans for such a support in Sql Compact Edition?
The following code accepts a couple of parameters and creates a temp table to hold unpaid schedule rows (like invoices). Then is takes the payment amount passed and starts paying the oldest ones first, until it runs out of money or pays a partial. When it pays it inserts a row in the applieds table with the schedule_ID, Receipt_ID (payment id), applied amount, and applied date.

I was just wondering if anyone could tell me how to do a search for a partial data match. Say one data field is 123, 234, 345, 456 and another is 111, 222, 333, 444 and another is 555, 666, 777, 888 and I want to search for the unique number 234 but not the whole number 123, 234, 345, 456 ... is there any way to do that or does every search have to be exactly like the data in the field? Thanks for any help. Dennis
In our database we have the concept of 'Companies' each company has an entry in a tblCompanyControls using a field lCompanyNumber to uniquely identify it.
Company specific data is then grouped within additional tables using this lCompanyNumber. Thus all the departments for a particular company (eg 4) exist in a table tblDepartments with lCompanyNumber =4. The same applies for pensions, pay elements, employees and so on.
Each employee has various attributes stored in several tables, thus the main data is stored in tblEmployees with an lCompanyNumber to illustrate the company they belong to. And a system generated lUniqueID that is the 1 to many relationship to tables such as tblEmployeePayElements, tblEmployeePensionSchemes.
These in turn have a primary key that establishes a 1 to many with the period data for pay elements etc.
What we want to do is replicate only the data for a specific company, for tblEmployees, tblDepartments this looks straightforward as i just set a filter like 'tblEmployees.lCompanyNumber = 4'. My problem is how do I replicate just the tblEmployeePayElements for those employees that are in the specific company as the table does not contain the lCompanyNumber. Can you replicate a view? I an quite ignorant of replication and would really appreciate some pointers. Note DRI is not in use.
I am serious problem of partial update my query is something like bEGIN tRAN declare cursor...
SElect * from tableA where flag = null
open cursor fetch first...
while @@FETCH_STATUS = 0 BEGIN UPDATE TABLE tableB .. . . .
fetch next END CLOSE ... DEALLOCATE.. COMMIT TRAN
The problem is the cursor select retrieves says about 10000 rows, goes thru the loop for 1000 rows and just terminates without giving an error message,or rolling back in case of errors, but comes out as successfully completed.
I am at loss as what could be the problems.. any suggestions welcome..
Could someone please help me? I am trying to pull in a partial string (the last six characters of the field, to be exact).
This is an example of my code:
select * into #temp_2 from #temp_1 a, Server2.DBa.dbo.table2 r where r.field1r = a.field1a and r.field3r = a.field3a (field3a is where I need just the last 6 characters)
To be more specific: r.field3r looks like 000884 a.field3a looks like 17445000884 So- I just want to pull in the 000884 off of a.field3a
etc like that. each row varies with one exception. administrator@sthou.com is in each one.
is there a simple way thru sql or T-SQL to delete that "administrator@sthou.com" part? or should i call each row individually into say, a VB.net form using a split with the deliminator ";" and then looping thru and updating each row?
We have here 3 tables which are linked by Order number. there is one more table we need to use to get the Shipping zone code. This column however is 10 pos. ( the order number on that table)whilst the others are all 8. We want to join on MHORDR in the table MFH1MHL0, then we are done.

I have been asked to see what I can recover from a development server whose database became suspect during a power failure.
One developer from another group who's time is limited tried to repair the database using checkdb, but it is still suspect.
There are no recent backups of anything whatsoever. Needless to say, we are lacking in DBA skills here. At this point, we don't care whether we get the data back, but we are desperate to recover the table definitions, user-defined functions and stored procedures -- if not all of them than most of them; if not most of them than some.
What are our options here?
Are their any good third-party tools to help us with this problem?
Hi all,I have 2 files containing Id numbers and surnames (these filesessentially contain the same data) I want to select distinct() andjoin on id number to return a recordset containing every individuallisted in both the files HOWEVER, in some cases an incomplete IDnumber has been collected into one of the 2 files -is there a way tojoin on partial matches not just identical records in the same way asyou can select where LIKE '%blah, blah%'??Is hash joining an option i should investigate?TIAMark

And then be able to summarize the results in the matrix.
I have a file where there is a partial row at the end. It doesn't cause an error, but I get a "partial row" warning during execution.
What do most people do with these partial rows? Do they just ignore them as long as they don't cause errors? Or is it better to handle the partial row with a conditional split, for example?
Just wondering what other people's thoughts on this are. I tend to be of the "get rid of it" camp, but maybe that's overkill? Just looking for opinions, best practices.
Hi - I am using partial backup & restore on a Data Warehouse database currently in development.
When I recently tested the restore procedure I got the following error when trying to an online restore of one of the ReadOnly filegroups:
Msg 3125, Level 16, State 1, Line 1
The database is using the simple recovery model. The data in the backup it is not consistent with the current state of the database. Restoring more data is required before recovery is possible. Either restore a full file backup taken since the data was marked read-only, or restore the most recent base backup for the target data followed by a differential file backup.
I believe I received this message as the Filegroup I was attempting to restore had been set ReadWrite since it was backed up.
So - I am looking for a query to test that all my filegroup backups are consistent with the live database.
I think I can achieve this by checking the read_write_lsn & read_only_lsn values for the filegroup to restore are the same as the values in sys.master_files for the live database.
I am reading the lsn values for the backup from msdb.dbo.backupfile
Can anyone confirm this is the correct approach? or is there a better way to do this??
