Group similar records by same ID in access - sql

I have a table full of clients in access and some are similar to each other (eg. NBC6, NBC10, etc.) I was wondering if there was a way to group all the similar clients and assign them all 1 ID. They would all start off the same so I was thinking to search for them like that but I'm unsure how to go about this in VBA. I am rather new to access and SQL so any help would be greatly appreciated!

Create a new field in your table called ClientGroup. Set its datatype to Text.
Get a list of all ClientGroup names you want to use. Let's say, for example, that NBC6 and NBC10 should end up in one group called NBC.
Run an Update query to assign that group:
UPDATE tblClients
SET ClientGroup = "NBC"
WHERE ClientName LIKE "NBC*"
The asterisk sign acts as a wildcard, so it will only update the records where the first 3 letters of ClientName are "NBC".
It's a lot of manual work, I suppose if you know you always want to use just the first 3 characters of a ClientName you can write a loop to put them in an array, but that's probably not the case.

Error in SQL SELECT with INNER JOIN

So, basically, I have two tables called "dadoscatalogo" and "palavras_chave", with a common field, "patrimonio" which is the primary key of "dadoscatalogo".
I'm using a servlet to connect to the database with these tables, and passing a query to search for entries based on some search criteria that's defined by the user.
Now, since the user can search for entries based on information present in both tables, I need to do an INNER JOIN, and then use WHERE to search for that info. I'm also using LIKE, because the user may pass just part of the information, and not all of it.
So, to test it all out, I tried passing it a few parameters to work with, and see how it went. After some debugging, I found out that there was some mistake in the query. But I can't seem to be able to point out exactly what it is.
Here's the test query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.patrimonio LIKE '%'
AND dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';
So, basically, what I'm trying to do with this query is, get all the primary keys from "dadoscatalogo" that are linked to a record with a "titulo" containing "tons", or a "palchave" containing "programming".
PS. Sorry for the names not being in English, hopefully it won't be too much of a distraction.
EDIT: Right now, the tables don't have much:
This is the dadoscatalogo table:
http://gyazo.com/fdc848da7496cea4ea2bcb6fbe81cb25
And this is the palavras_chave table:
http://gyazo.com/6bb82f844caebe819f380e515b1f504e
When they join, I'm expecting it to have 4 records, and it would get the one with patrimonio=2 in dadoscatalogo (which has "tons" in titulo), and the one with palchave=programming (which would have patrimonio=1)
As per my understanding run below query:
SELECT dadoscatalogo.patrimonio
FROM dadoscatalogo
INNER JOIN palavras_chave
ON dadoscatalogo.patrimonio=palavras_chave.patrimonio
WHERE dadoscatalogo.titulo LIKE '%tons%'
OR palavras_chave.palchave LIKE '%programming%';

SQL Server: Remove substrings from field data by iterating through a table of city names

I have two databases, Database A and Database B.
Database A contains some data which needs to be placed in a table in Database B. However, before that can happen, some of that data must be “cleaned up” in the following way:
The table in Database A which contains the data to be placed in Database B has a field called “Desc.” Every now and then the users of the system put city names in with the data they enter into the “Desc” field. For example: a user may type in “Move furniture to new cubicle. New York. Add electric.”
Before that data can be imported into Database B the word “New York” needs to be removed from that data so that it only reads “Move furniture to new cubicle. Add electric.” However—and this is important—the original data in Database A must remain untouched. In other words, Database A’s data will still read “Move furniture to new cubicle. New York. Add electric,” while the data in Database B will read “Move furniture to new cubicle. Add electric.”
Database B contains a table which has a list of the city names which need to be removed from the “Desc” field data from Database A before being placed in Database B.
How do I construct a stored procedure or function which will grab the data from Database A, then iterate through the Cities table in Database B and if it finds a city name in the “Desc” field will remove it while keeping the rest of the information in that field thus creating a recordset which I can then use to populate the appropriate table in Database B?
I have tried several things but still haven’t cracked it. Yet I’m sure this is probably fairly easy. Any help is greatly appreciated!
Thanks.
EDIT:
The latest thing I have tried to solve this problem is this:
DECLARE #cityName VarChar(50)
While (Select COUNT(*) From ABCScanSQL.dbo.tblDiscardCitiesList) > 0
Begin
Select #cityName = ABCScanSQL.dbo.tblDiscardCitiesList.CityName FROM ABCScanSQL.dbo.tblDiscardCitiesList
SELECT JOB_NO, LTRIM(RTRIM(SUBSTRING(JOB_NO, (LEN(job_no) -2), 5))) AS LOCATION
,JOB_DESC, [Date_End] , REPLACE(Job_Desc,#cityName,' ') AS NoCity
FROM fmcs_tables.dbo.Jobt WHERE Job_No like '%loc%'
End
"Job_Desc" is the field which needs to have the city names removed.
This is a data quality issue. You can always make a copy of the [description] in Database A and call it [cleaned_desc].
One simple solution is to write a function that does the following.
1 - Read data from [tbl_remove_these_words]. These are the phrases you want removed.
2 - Compare the input - #var_description, to the rows in the table.
3 - Upon a match, replace with a empty string.
This solution depends upon a cleansing table that you maintain and update.
Run a update query that uses the input from [description] with a call to [fn_remove_these_words] and sets [cleaned_desc] to the output.
Another solution is to look at products like Melisa Data (DQ) product for SSIS or data quality services in the SQL server stack to give you a application frame work to solve the problem.

Nested Lookup Functions? Need to match up two things

So I'm working in microsoft sql server report builder and here is essentially what I'm trying to do in code:
(Under report variables)
vChargeStatusID = Lookup(Fields!CREDIT_CARD_TRANSACTION_ID.Value, Parameters!CREDIT_CARD_TRANSACTION_ID.Value, Fields!CHARGE_STATUS_ID.Value, "DataSet1")
(As an expression for a filter)
Lookup(Variables!vChargeStatusID.Value, Fields!CHARGE_STATUS_FK.Value, Fields!CONTRACT_NUMBER.Value, "DataSet1")
I've tried using the variable and the expression for the variable to try to create another calculated field, but no luck. I keep getting the error that I can't use nested lookup functions.
Basically what I'm trying to do is, first, find two things that are equal to each other to retrieve a number. Then I need to take that number and match it to something else to finally return the contract number.
I cannot figure this out.
Any help would be great.
So, a very simple way to accomplish this is to place a field on your report (TextBox1.value) that will hold your first lookup value.
For example, your first look up will return a vendor ID (DataSet2) from a customer order (DataSet1).
TextBox1.expression = Lookup(Fields!CustOrderID.Value,Fields!CustOrder_ID2.Value,Fields!VendorID.Value,"DataSet2")
But now you need to find the vendor name from a Vendor Master table (DataSet3). You can do another look up to the Vendor Master table using the ReportItems!TextBox1.value as the first value of the look up. That way you do not get the scope issue.
TextBox2.expression = Lookup(ReportItems!Textbox1.value,Fields!VendorID.Value,Fields!VendorName.Value,"DataSet3")
All credit goes to my boss who figured this out!
Step one: Create another dataset, which is embedded. This dataset then has a filter that takes a field, in this case it's CREDIT_CARD_TRANSACTION_ID, and evaluated it be true to the parameter, pCreditCardTransactionID. This makes sure that the second dataset is ONLY going to display to me the Contract number, which is the very last thing I needed from the Lookup Function.
Step two: Create an internal parameter that the default value is set to the field CONTRACT_NUMBER from the second dataset (ContractNumberLookup).
Step three: Create a filter on the table. The CONTRACT_NUMBER from the original dataset is set to equal the internal parameter.
Tada!
I hope this helps. If any clarification is needed, let me know!

SQL select certain number of rows

Hello I need a SQL query statement that gets me rows 'start' to 'finish'.
For example:
A website with many items where page 1 selects only items 1-10, page 2 has 11-20 and so on.
I know how to do this with Microsoft SQL Server and MySQL but I need an implementation that is platform independent. :/
I have an Increment line for IDs but deleting in-between will mess the result when I select via
WHERE ID > number AND ID < othernumber
of course
Is this possible without fetching the whole database to a ResultSet?
I think your safest bet would be to use the BETWEEN operator. I believe it works across Oracle/MySQL/MSSQL.
WHERE ID BETWEEN number AND othernumber
Concerning your comment " I was just think for the case when first 100 IDs are gone I'll have to check further until there is something to fetch", you might wanna consider NOT actually ever deleting stuff from your database but to add a flag like "active" or something like that to your tables so you can avoid situations like the one you're now trying to avoid. The alternative is where you are now, having to find the max and min rows in a filter

How to design a database table structure for storing and retrieving search statistics?

I'm developing a website with a custom search function and I want to collect statistics on what the users search for.
It is not a full text search of the website content, but rather a search for companies with search modes like:
by company name
by area code
by provided services
...
How to design the database for storing statistics about the searches?
What information is most relevant and how should I query for them?
Well, it's dependent on how the different search modes work, but generally I would say that a table with 3 columns would work:
SearchType SearchValue Count
Whenever someone does a search, say they search for "Company Name: Initech", first query to see if there are any rows in the table with SearchType = "Company Name" (or whatever enum/id value you've given this search type) and SearchValue = "Initech". If there is already a row for this, UPDATE the row by incrementing the Count column. If there is not already a row for this search, insert a new one with a Count of 1.
By doing this, you'll have a fair amount of flexibility for querying it later. You can figure out what the most popular searches for each type are:
... ORDER BY Count DESC WHERE SearchType = 'Some Search Type'
You can figure out the most popular search types:
... GROUP BY SearchType ORDER BY SUM(Count) DESC
Etc.
This is a pretty general question but here's what I would do:
Option 1
If you want to strictly separate all three search types, then create a table for each. For company name, you could simply store the CompanyID (assuming your website is maintaining a list of companies) and a search count. For area code, store the area code and a search count. If the area code doesn't exist, insert it. Provided services is most dependent on your setup. The most general way would be to store key words and a search count, again inserting if not already there.
Optionally, you could store search date information as well. As an example, you'd have a table with Provided Services Keyword and a unique ID. You'd have another table with an FK to that ID and a SearchDate. That way you could make sense of the data over time while minimizing storage.
Option 2
Treat all searches the same. One table with a Keyword column and a count column, incorporating SearchDate if needed.
