2 abc NULL
2 aaa NULL
4 xyz NULL
4 xyz pqr
4 pyz xqr
I want to get only one record for each record number. that is, the
result set should be like this:

Hello
I am trying to write and SQL query...
I have a table with 4 columns, ID, Key, Value and SiteID.
SiteID can be Null or an int.
As an example I could have these four rows,
ID=1, key=colour, value=red, siteID=Null
ID=2, key=colour, value=green, siteID=2
ID=3, key=font, value=arial, siteID=2
ID=4, key=size, value=6,siteID=Null
My query will pass in a siteID and I need to bring back all rows with that site ID plus any rows whos key I haven't already got who's siteID =Null.
The Null site ID is default, so it always needs to bring back the null if a key doesn't exist with a siteID.
Does anyone know if that is even possible with just a straight SQL query?
Thanks
Becky

Hi I have been tearing my hair out trying to resolve this problem.
A form is submitted with a number in to checkthe database for the items with that number of items in the quantity field(s) and display them.
There are 2 relevant Tables in the 2005 server SQL Database, One called "Products" the other called "ProductDetails"
In both tables is a field called Quantity, this hold a numerical value for the quantity of the product.
Some products have additional attributes such as sizes or colours and these are stored in the ProductDetails table.
Every product is stored in the "Products" table and has a unique ProductID, where a product has additional attributes, these along with the ProductID and the quantity for that particular attribute are stored in the ProductDetails table.
I am trying to loop through the database and produce a list of all the items and if they have any additional size or colour attributes then display these too, and if they dont have additional attributes then just display the product details and quantity stored in the Products table.
What I have actually done instead is produce a list of every item and every attribute in the database, but for example Where product 1 doesnt have any attributes, and neither does product 2, but product 3 and product 3 do, when the details are displayed on the page (Using ASP),
Rather than displaying product 1 details and the quantity in the "Products" table, product 2 and the details & quantity in the Products table, then product 3 and each of the attributes & Quanity pertaining to that item in the "ProductDetails" table, and so on, it shows every item as having every combination of attributes,
so although products 1 and 2 have no attributes, it will show product 1 with the first attribute of the other products and then show another product 1 with the next attribute from another product and keep going untill all the attributes in the whole of the Product details table is shown , then do the same thing with product 2 and then product 3 and so on.....
Also the products that have no attributes are not only shown with the attributes that they dont have, they are not shown without attribues and with the correct details in the list.
Here is my string, which has changed a million times, I am just learning as I go along so if it is obvious please be pateient with me and help me out...
rsResults.Source = "SELECT DISTINCT Products.ProductID, Products.ProductName, Products.ProductPict, Products.Quantity, ProductDetails.ProductDetailID, ProductDetails.P_Size, ProductDetails.P_Color, ProductDetails.Quantity FROM Products, ProductDetails WHERE Products.ProductID = Products.ProductID AND Products.Quantity <= "& +rsResults__var1 & " OR Products.ProductID = ProductDetails.ProductID AND ProductDetails.Quantity <= "& +rsResults__var1 & " Order by Products.ProductID asc "
Can anyone see why it is doing this instead of only showing the attributes next to the items that have attribues?
Please help
Warm Regards,
Joe

I am trying to use ssis (sql query or .net-script task)
to transfer data from one table to another.
I have difficulties to make the query:
i have one table tbl_games which fields are :
type ,startDateTime, EndDateTime, playerId.
I need to check every 1/2 hour according to the startDateTime,
How many times a person is playing and to show it in a new table
tbl_collectData like this:
TimeplayerId Games_0-30_secondsGames_30-50_seconds
8-8:30 A 3 2
8:30-9B 2 10
9-:30C 20 7
The length of the game is measured by the StartDateTime -EndDateTime,
and only games type # 2 is being collected.
The number 3 example is: 3 games that lasted between 0-30 seconds and were played between 8-8:30 by player A, and the game type is 2.
I tryed to start by doing something like this , but it is not a complete query:
INSERT INTO tbl_collectData
(Time, playerId, Games_0-30_seconds)
SELECT '12 / 26 / 2007 4 : 53 : 03 PM' AS Expr1, playerId, COUNT(DATEDIFF(ss, StartDateTime, EndDateTime)) AS numberOfCalls_0_30
FROM tbl_games WHERE (Type = 2) AND (DATEDIFF(ss, StartDateTime, EndDateTime) < 31) AND (StartDateTime > '12 / 26 / 2007 4 : 53 : 03 PM') AND
(StartDateTime < '12 / 26 / 2007 5 : 23 : 03 PM')
GROUP BY playerId
I just don't know how to do it! Please help!!!!

Hi,I have two tables Trade table and Cons table. Records are inserted inboth the tables independent of each other. There are fields likeExc_Ref, Qty, Date in both the tables.I need to write a query which should give me records :1. Where there is missing Exc_Ref value in either of the table. i.e.If Trade table has a Exc_Ref value but missing in Cons table then thatrecord should be displayed. Similarly if Cons has a Exc_Ref valuewhich is not found in Trade table then that too should be displayed.2. In case where both the tables have matching Exc_Ref data then itshould display the record only when the remaining column does notmatch like Qty or Date.Please help me to resolve this complicated query.ThanksNick

Hi Guys
I Have not been able to solve this problem from quiete a while now.
I am using sql server 2005.
I have got a table which contains these columns - start date, end date and volumes
if the month in the start date is same as that of end date, the volume remains same, else if the months in the two dates are different, then i have to distribute the volume in such a way that some part will go in the first month and the rest in the other month.. i have to somehow calculate (or prorate) the volume according to the no of days in each month
I have to perform a query on this table so that I can group the volumes for different months and different years.
Here is the sample data...

I'll start by giving the basic idea of the data structure I'm looking at in the database (pardon my MS Paint skills!):
And this all starts with a root plan. So (taking projects out of the picture for the minute), it could be a structure going any number of levels down like so: plan -> goal -> strategy -> plan -> goal -> strategy -> plan -> goal -> strategy, etc.And not forgetting, that a strategy can also have any number of projects, and all these relationships are one to many, so it ends up being like a large tree structure.
What I am trying to accomplish is user security related, in that I need to enforce rules set to say whether a single user is allowed to view a project. You can define the rules at any level in the structure above. So if for instance, a user is given a rule that they can access anything from a goal, they can see any projects that exist in any strategies underneath that goal in the tree structure. I hope this is making sense so far... The rules can also just be defined at a specific project level.
These rules (at the moment, I'm more than happy to change if this is a silly way of doing it) are set in a table that has the columns:user_id intplan_id intgoal_id intstrategy_id intproject_id intallow bitEvery row will have a user_id value, and one of either a plan_id, goal_id, strategy_id or project id (which I thought would be a simple way to pull out what kind of rule if needed), and the allow column just defines if it's an allow or deny rule (a specific deny rule on any object lower in the tree structure will override any cascaded allow rule).
The way my application needs to grab this information, is to simply have some way of returning a list project_id values for which the current user is allowed to access. I'm basically stumped. The closest I have gotten (which still didn't quite work) was going to end up using quite a large number of cursors... Which is bad. It can be inefficient to an extent, as once these values are gathered once, I can store them in a Session variable, so it's not grabbing them every time the user tries to load a project.
Thanks for any help!

Hi,
I am positive some SQL Gurus can help me with this complicated query. I am not sure if it is possible with a single query or needs multiple queries.
I have 3 objects. First, PaintOrder; Second, Combination; and Third, Material. Each Paint Order can have multiple Combinations and each Combination can have multiple (from 0 to 5) Materials. All the data is stored in single table called paintMatCom.
Here is the sample Data
PaintOrderId CombId MaterialId
1000 1 1
1000 1 2
1000 2 3
2000 1 1
2000 2 3
2000 2 4
3000 1 1
3000 1 2
3000 2 3
3000 3 4
3000 3 5
I have a Search Screen where user can select multiple Materials (upto 5) to search for the appropriate PaintOrders. Also, use has the option to select AND/OR between materials. Please look at the attached image for clear understanding.
Some of the sample searches are as follows (Combination IDs are not needed in the Output; just PaintOrder IDs).
1. Find PaintOrders with MaterialIDs 1 AND 2 OR 4
2. Find PaintOrders with MaterialIDs 2 OR 3 OR 4
3. Find PaintOrders with MaterialIDs 3 AND 4 OR 5 OR 1
Hope you got the idea. I think it would require some Joins and GROUP BY which I am not expert at. I would appreciate any help.

You can display both by referring to their position in the recordset or by aliasing them in the query and referring to the alias in your code.
Note that in order to put Products.Quantity or ProductDetails.Quantity in just one column you'll have to add some logic in the query, using a coalesce, like:
sql Code:
Original
- sql Code
SELECT
Products.ProductID, Products.ProductName, Products.ProductPict,
COALESCE(Products.Quantity, ProductDetails.Quantity, 0) Quantity,
ProductDetails.ProductDetailID, ProductDetails.P_Size, ProductDetails.P_Color
FROM
Products
LEFT OUTER JOIN
ProductDetails
ON Products.ProductID = ProductDetails.ProductID
WHERE
Products.Quantity <= "& +rsResults__var1 & "
OR
ProductDetails.Quantity <= "& +rsResults__var1 & "
Order by Products.ProductID asc;
SELECT Products.ProductID, Products.ProductName, Products.ProductPict, COALESCE(Products.Quantity, ProductDetails.Quantity, 0) Quantity,ProductDetails.ProductDetailID, ProductDetails.P_Size, ProductDetails.P_ColorFROM Products LEFT OUTER JOIN ProductDetails ON Products.ProductID = ProductDetails.ProductID WHERE Products.Quantity <= "& +rsResults__var1 & " OR ProductDetails.Quantity <= "& +rsResults__var1 & " ORDER BY Products.ProductID ASC;
Untested, beware of syntax errors!
In this case you'll have just one Quantity colum and you won't have to change anything in your asp code.

I have run into a problem, I have 2 fields in my database, both key fields:
Table 1
=====
Field X <key>
Field Y <key>
In field X, there are say about 3 records for each unique Field Y. I let my users query the data base like follows:
Enter the Codes you want: 1000 and 3000 and 8500
So I want to pick up records where there will be the above values for All Y values. i.e 1000/AAA, 3000/AAA, and 8500 for AAA - if there is even ONE of the X values not matching a record without a matching X value, leave it out.
i.e:
X=1000,Y=AAA
X=3000,Y=AAA
X=8500,Y=AAA
X=1000,Y=BBB
X=3000,Y=BBB
X=8500,Y=BBB
X=1000,Y=CCC
X=3000,Y=CCC
X=9999,Y=CCC
When the query runs, I want to see the following records:
X=1000,Y=AAA
X=3000,Y=AAA
X=8500,Y=AAA
X=1000,Y=BBB
X=3000,Y=BBB
X=8500,Y=BBB
BUT NOT:
X=1000,Y=CCC
X=3000,Y=CCC
X=9999,Y=CCC
because one of the X values was not matched (the last X value =9999 and not one of the requirements of the search)
So I guess I want something like this:
SELECT X,Y from TABLE1 WHERE ALL Y VALUES HAVE ALL OF THESE X VALUES (X=1000,X=3000,X=8500) IF ANY X VALUES ARE MISSING SKIP RECORD
^^ Hope the above makes sense... but I am really stuck. The only other way I think I could do it is, copy all records that match all 3 X values into a temp table, and weed out any that are missing any one of the X values after they are copied but, I am running this on MYSQL 5.0 Clustered, and there is not enough room in memory for it probably... and query time has to remain under a second.
Anyhelp would be appreciated...

Hi,
hope someone can help or suggest something to help me with the issue.
I have a list of projects. this list contains all master (parent) and all subprojects(child). when I click on a project I want to be able to retreive information about that project and it's subprojects. here is my delema. I want my sql query to check if project is master or sub. if master then get all data for this project and its subprojects but if it's sub then get data only for that sub. below is a sample data that I hope it clear things up
parent_ID child_id Type projname
-----------------------------------------------
100 100 P parent_X_proj
100 25 C child_X_proj
100 29 C child_X_proj2
200 200 P parent_Z
300 300 P parent_Y
etc................
this is how my table is constructed. my application passes child_id and what I want is if someone clicks on parent_X_proj I want to be able to retreive the three projects (100,25,29) but if someone clicks on child project (29) then I want only that project.
so I want my query to look for the type and if my type is P (parent) then get all project where parent_id = 100(for example) but if type= C then get child_id = 29.
I know it could be done in stored procedure buy my application cannon executre SP but only sql statements.
Thank you for any help

SQL2K on W2KserverI need some help revamping a rather complicated query. I've given thetable and existing query information below.

I'm not sure if this is even possible but can i pull out rows from two tables (that have a one-to-many relationship) but only if they satisfy a few conditions.
tblWine tblSources
ID Name ID WineID Source Price Status

1 Le Dome 1 1 Smith 100.00 IB

4 2 Smith 135.00 DP
5 2 Hill 125.00 DP
I only want to pull out row that contain the cheapest wine for their status. So the result would look something like this.

Perhaps you can help with something that I consider kind of omplicated? (I am SO hoping that I am NOT going to have to do this manually!!!)
I have a table (about 3000 rows) where two of the columns have Domain User information.
COL1 has DOMAINUsername and COL2 has (or SHOULD have) DOMAIN@username.com
I need to look at each field in COL1 and if exists DOMAINusername, I need to populate COL2 with username@DOMAIN.com
Is this possible???

The low down:
Local Web Server on Windows 2003
Local SQL Server on Windows 2003
Hosting dynamic website tied to inhouse Access Application
Ok, basically, how it is set up, people can login to our website and enter data (insert record), on our end, we have an Access application where we can play with the data that was entered via the website. Currently, we do not have either server set up as a Mail server.
What we need to be able to do:
When a customer enters data on our website, their supervisor, and about 2-3 other people related to the transaction need to be emailed to be notified that an order was submitted. So how do I code that? On the page with the Insert Record? OR after Insert Record redirect them to another page that sends the mail out?
Which server do I enable the mail?
I was reading about SQL Mail etc, which would be good since we do mass emails to clients weekly, but I have no idea how to set that up and I look crossed eyed at any tutorial.
Do I want to set up theSQL server to also be a Mail Server that way we can use the SQL database to email as well as data entered from the website? But then again, the website points to the Web Server which pulls data off the SQL server (so unless the Web Server is a mail server, nothing will be sent, am I right?)
*sigh*
I know very little about SQL and I'm being asked to impliment this and I am 100% confused. I'm a graphics artist not a programmer! LOL
Thanks in advance to anyone who can/will help me.

All I am trying to do is use a SqlDataSource, Read that Data from the Session Variable, Do a RowFilter off the Data and then return the Data (Currently a DataSet but doesnt matter). But Since I dont use SqlDataSource that much not sure all the code I have is neccasry:
protected DataSet GetSearchAppData(string strWhere)
{
DataSet dsSearchAppTable = new DataSet("SearchAppTable");
SqlDataSource ss = new SqlDataSource();
DataView dv = new DataView();
DataSourceSelectArguments dsArgg = new DataSourceSelectArguments();
dsArgg = DataSourceSelectArguments.Empty;
ss = ((SqlDataSource)Session["SearchAppTable"]);
dv = (DataView)ss.Select(dsArgg);
dv.RowFilter = strWhere;
dsSearchAppTable.Tables.Add(dv.Table.Clone());
return dsSearchAppTable;
}
And to mention it, dsSearchAppTable returns a Table with 0 rows. Not sure what the heck I'm doing wrong.

Hello guys,
I am askng for any help ...am trying to get this SQL language.
I want to provide an SQL query to set all the priority to 1 for all customers that have all their orders being for a product with importance of 100.
--------------------------------------------------------------------
There are three tables in the database: Customer, Product and Orders.
The Customer table has three column: Customer_id (PK), priority, Address.
The Orders table has three colums as well: Order_id (PK), Customer_id (FK), Product_id (FK)
The Product table has three columns as well: Product_id(PK), Product_name, Importance.
So the order table is connected to both the product and the customers table by respective foreign key.

Our office uses a program to keep demographic and private customer information. This program is installed in a Dell PowerEdge Windows 2000 Server with 8 desktops spread throughout the office for our employees to use. We back the SQL database up every night on 2 WD external HD that we rotate and the server does a nightly backup too. Our software vendor is changing to a different software program that we don't care for since our current software works so well. As a result, we want to keep using the original software. Here's my question:
If we choose to stay with the original software, do we need this software to read and print out the SQL database for individual customers forever? In other words, if this software fails, is there a way to read and print the existing records without using the original software? Our software vendor tells us that our version will be discontinued and no support will ever be available again. But since we are required to keep our records for many years down the road, we need a way to print this information out if the customer wants to have a copy say 5 years from now. Is there any way to do this without the original software? Thank you very much for your help and opinions.

The best way to explain this is by example.I have a source table with many columns.SourceSYMBOLEXCHANGE_NAMECUSIPTYPEISSUE_NAMEand so onThen I have 3 other destination tables.ExchangesEXCHANGE_ID IDENTITYEXCHANGE_NAME UNIQUESecurityMasterSECURITY_MASTER_ID IDENTITYSYMBOL UNIQUECUSIPTYPEISSUE_NAMEand so onExchange_mm_SecurityMasterEXCHANGE_IDSECURITY_MASTER_ID-- The Source table has multiple rows of the same symbol.-- The Exchanges table is already populated with all the exchanges.-- A single security (in the SecurityMaster table) can belong to manyExchanges, hence the Exchange_mm_SecurityMaster table.Now. If I just wanted to insert into the SecurityMaster table withouttouching the Exchange_mm_SecurityMaster table I could just execute:INSERT INTO SecurityMaster ([SYMBOL], [CUSIP], [TYPE], [ISSUE_NAME])SELECT DISTINCT[SYMBOL], [CUSIP], [TYPE], [ISSUE_NAME]FROM SourceWHERE NOT EXISTS (SELECT * FROM SecurityMaster SM WHERE SM.SYMBOL =Source.SYMBOL)Now to the Exchange_mm_SecurityMaster. I need the individual identityvalues for each row inserted into SecurityMaster so I can then turnaround and insert into Exchange_mm_SecurityMaster. Here are theissues/possibilities as I see it.- @@IDENTITY will not work since I am not inserting a single row at atime- I guess I could INSERT INTO SecurityMaster first, THEN do anotherINSERT INTO Exchange_mm_SecurityMaster with different where clause.- I could create a stored procedure that does a single insert intoSecurityMaster and Exchange_mm_SecurityMaster. Then call thatprocedure for each row in the SELECT DISTRICT from the Source table.My main worry is the number of arguments passed in. My example onlyshows a few but a regular SecurityMster table could have 30-50columns.- Maybe do something with a trigger but I am not sure if I can passthe EXCHANGE_NAME value to the SecurityMaster trigger when that tabledoes not need it.Hope I explained it clearly. Any help would be appreciated.

Hi,
My users table contains a field called researchInterestId which looks like this: 1, 5, 10
This is because users where allows to select multiple options when choosing their research interests.
I have another table which contains the names of those research interests, which looks like this:
researchInterestId researchInterestName
1 Biology
2 Cancer
My question is, when selecting my list of users, i wish to also display the names of their research interests. I know how to inner join but im not sure in this case as there are multiple values (1, 5, 10)
Hope that makes sense and that someone can point me in the right direction or let me know what this type of query is called?
Thanks
Sam

Hi,
for my website im going to be selling rims, and i need to have available a search by vehicle
SKU: 8438743
CAT: RIM
BRAND: ADVAN
MODEL: KREUZER_SERIES_V
DIAMETER: 17
WIDTH: 8
OFFSET: 45
LUGS: 5
LUG SPACING: 114.3
FINISH: GMETAL
that would be the determing factors of the results, heres what would define for example a
2002 Accord V6
LUGS = 5
LUG SPACING = 114.3
55 > OFFSET > 40
DIAMETER < 20
WIDTH < 9
so for the accord
the required attributes are a 5X114.3 lug pattern
the offset needs to be 40-55
max diameter is 19"
max width = 8"
My question is this, how many databases do i need to make? and what catagories do I use in each database? Also is it possible to do less than, greater than, etc, in databases? I think thats everything, thanks!

I have the following stored procedure that I use for an update. The table now has just over two million rows and the stored procedure takes days to run. I am looking for any help that would produce the same results faster. This runs on SQL Server 6.5, on an NT machine with 4 pentium pro 200 processors and 512 MB of RAM so I am relatively sure that the performance issue is in the below statement.
UPDATE PAY_CHECK_DETAILS
SET JobID = j.JobID
,HROrganizationID = j.HROrganizationID
,JobDetailID = j.JobDetailID
,GLAccountNumber = j.GLAccountNumber
FROM JOBS j, PAY_CHECK_DETAILS p
WHERE j.EmployeeID = p.EmployeeID
AND j.HRActionEffectiveDate =
(SELECT max(HRActionEffectiveDate)
FROM JOBS jj
WHERE p.EmployeeID = jj.EmployeeID
AND jj.HRActionEffectiveDate <= p.PayDate)
AND j.HRActionSequence =
(SELECT max(HRActionSequence)
FROM JOBS jjj
WHERE p.EmployeeID = jjj.EmployeeID
AND jjj.HRActionEffectiveDate =
(SELECT max(HRActionEffectiveDate)
FROM JOBS jjjj
WHERE p.EmployeeID = jjjj.EmployeeID
AND jjjj.HRActionEffectiveDate <= p.PayDate))
AND NOT (ISNULL(p.JobID,1) = ISNULL(j.JobID,1)
AND ISNULL(p.HROrganizationID,'A') = ISNULL(j.HROrganizationID,'A')
AND ISNULL(p.JobDetailID,1) = ISNULL(j.JobDetailID,1)
AND ISNULL(p.GLAccountNumber,'A') = ISNULL(j.GLAccountNumber,'A'))
Thanks for any help or suggestions you have.

I have a table that has attendance for programs. What I need to get is the number of days each month that any program had an entry for. What I'm trying to do is ensure that an active program had all entries for that particular month.
I can do this query and subquery in Access but not in sql. Here's the Access queries:
1)SELECT Cen_DailyReport.PgmID, DatePart("m",[date]) AS Mo, DatePart("d",[date]) AS Dy
FROM Cen_DailyReport
WHERE (((DatePart("yyyy",[Date]))=2004))
GROUP BY Cen_DailyReport.PgmID, DatePart("m",[date]), DatePart("d",[date])
HAVING (((Cen_DailyReport.PgmID)="dyad"));
Then to get the actual day count per month, the next query is:
2) SELECT Query11a.PgmID, Query11a.Mo, Count(Query11a.Dy) AS CountOfDy
FROM Query11a
GROUP BY Query11a.PgmID, Query11a.Mo;
and this query aggregates the data from the 1st query. I'm wanting to do this in SQL.
In the long run, I want to take that count in the query and compare it with the actual number of days in a month to see if any entries are missing (like a program not being entered at all on any given day that they should have had entries for)
Any help would be appreciated.

I have the table tbOld with columns as fieldID (PK), Class, Name, other1, other2, other3 and tbNew with the same structure (fieldID (PK), Class, Name, other1, other2, other3).
Most Class-Name combinations are the same in both tables but have different FieldID, others are only in the 'tbNew' and absent in the tbOld, some are only in the 'tbOld' but we are not interested in those.
We need to update data in tbNew for columns other1, other2, other3 and make them the same as in tbOld where possible (where class-Name combination is present in the tbOld)
The update statement based on the join on two columns does not work (both columns are not PK, as FieldID is PK in each table, but we can't join on it)
Any help is highly appreciated.

I'm having some trouble coming up with the correct select statement.Lets say I have the following two tables:---------------- ----------------Orders OrderItem---------------- ----------------PK OrderID (int) PK OrderItemID (int)OrderDate (datetime) FK OrderID (int)CustomerName (nvarchar) Priority (int)My search would basically return a list of all the orders placed withinthe last week. The select statement would include the entire contentsof the Orders table. The tricky part is that I also need to return thenumber of items within each order that have a priority of 1 (so theycan be displayed more prominently).The first part of the select statement is easy enough, but I'm stuck onthe count part. I'd appreciate any help. Here's what I have so far:SELECTOrders.OrderID,Orders.OrderDate,Orders.CustomerNameFROMOrdersWHEREDATEDIFF(dd, Orders.OrderDate, GetDate()) < 7--Jason

Befor question let me give you the tables, so simple:
tblProduct tblProductLang
ID ProductName Cost ID ProductName Lang
------------------------------------- -------------------------------------
1 Pencil 1 1 Bleistift gr-GR
2 Paper 1 2 Papier gr-GR
3 Button 2 3 Taste gr-GR
4 Mouse 15 4 Maus gr-GR
5 Monitor 45 4 Souris fr-FR
Ok. We have two table,
tblProduct: Keeps the product name and cost
tblProductLang: Keeps the product name in different language and short name of the language.
We are about the make a language file to our website. Default language is english. So no problem with the product name, user can easily understand. If yuser selects german , english names of the product will be nothing for him/her. We make a language table for products so when user changes language, he/she will get product name of the preffered language, if there is no equivalent name of that product, result will be default name. Let me give you a sample output:
If user wants gr-GR language , result will be: If user wants fr-FR language , result will be:
ID ProductName Cost ID ProductName Cost
------------------------------------- -------------------------------------
1 Bleistift 1 1 Pencil 1
2 Papier 1 2 Paper 1
3 Taste 2 3 Button 2
4 Maus 15 4 Souris 15
5 Monitor 45 5 Monitor 45
As you can see ID 1,2,3,4 came from tblProductLang as German, but ID 5 has no equivalent so it came from tblProduct as English.(Same thing for the french.) So question is how can i do that?
