Hello, I am trying to essentially create an inner join. However, the thing that makes my case unique is, I need to do an inner join "twice".
I have SomeTable:
ID
Name
Item1ID
Item2ID
ItemTable:
ID
Name
Description
I need to do a query on SomeTable and retrieve a specific result based upon the ID. When I return that result, I want to return the two Item names that correspond with the result. I need this to act like a left join because the item id may not exist in the ItemTable. Does anyone know how to write a query like this?
Heya, I'm stuck on this query, we are currently moving from mysql to mssql, and this one has stumped me.
I used to use CONCAT, and i thought i'd found the correct syntax for MSSQL but it fails when used.
Code:
$sql = " SELECT * FROM ol_user_2_group ug INNER JOIN ol_users_details ud ON ug.user_id = ud.user_id INNER JOIN ol_user_rank ur ON ug.user_id = ur.user_id WHERE ug.group_id= ".$group_id." AND ud.firstname + ' ' + ud.lastname AS fullname LIKE '%".$search."%'";
ud.firstname + ' ' + ud.lastname AS fullname LIKE '%".$search."%'";
How many result-rows does mssql return should be used asynchronous method to use mssql cursor, can get the best performance in any time in any result offset?
i want to make the cursor fast in any time whatever how many results returned
i was planning to create a database migration tool .. its a certain database of a DMS (document management system) to another DMS (two different DMS)... from DMS using msde 2000 server .. and tranfer to a DMS using a postgre sql or mssql .. depends ..
they have different table structures and names . . :D
i was thing of what language shall i use.. or what language is the best to work on this kind of project :)
Does enabling/disabling Data Execution Prevention have a performanceimpact on SQL 2000 or SQL 2005?For SQL best performance - how should I configure for:Processor Scheduling:Programs or Background servicesMemory Usage:Programs or System Cache
I am a bit new to the MSSQL server. In our application, we use so many SQL queries. To imporve the performance, we used the Database enigine Tuning tool to create the indexes. The older version of the application supports MSSQL 2000 also. To re-create these new indexes, I have an issue in running these "CREATE INDEX" commands as the statements generated for index creation are done in MSSQL 2005. The statements include "INCLUDES" keyword which is supported in MSSQL 2005 but not in MSSQL 2000.
Ex:-
CREATE INDEX IND_001_PPM_PA ON PPM_PROCESS_ACTIVITY
I am currently work on mssql 6.5. On my workstation, I have mssql 6.5 cient software.
However, I would like to install mssql 7.0 server on my nt workstation and work with it to become familiar with 7.0. Can I install mssql 7.0 server on my nt workstation? Can mssql 6.5 client coexist with mssql 7.0 on the same machine if they are in different directories?
Ben writes "I have a sql script that doesn't function very well when it's executed on a SQL 2000 server.
The scrpt looks like this:

I need to be converted to a script that can be executed on both MSSQL 2000 and MSSQL 2005.
I was wondering if somebody there could help me with this problem?!
I've been tasked to move our production databases on MSSQL 2000 to 2005. I've supported MSSQL since version 6.5 and performed migrations to successor versions.
Current Environment is MSSQL 2000 32-bit with current Service Packs.
I've performed mock migrations on Test servers upgrading all Production instances simultaneously from MSSQL 2000 to 2005 32-bit. The Test environment is identical to Production minus server name, IP etc. Also I have a separate server with MSSQL 2005 installed where I use the DETACH / ATTACH and BACKUP / RESTORE method for migration / acceptance testing. There are approximately 30 databases totaling 70 GB. This has gone as expected and fairly successful. Vendors have been coordinated with to update code and staff for acceptance testing.
I'd prefer going directly to MSSQL 2005 64-bit instead if possible due to memory benefits etc. This is where I'd like some feedback prior to borrowing a 64-bit server for testing.
Upgrade options:
1. Is it better to migrate from MSSQL 2000 32-bit to 2005 64-bit via: a. DETACH / ATTACH b. BACKUP / RESTORE c. Is one method more advantageous relating to the end result? 2. Regarding XP clients, have issues been experienced with the default SQL Server driver or is an alternate recommended for XP clients to connect to a MSSQL 64-bit server databases? 3. If you have performed this migration and have relevant experience please pass them along.
DB is developed on local computer with MSSQL 2005 Express. My host is on MSSQL 2005 workgroup. Are they compatible, because I am getting errors? Is my approach wrong?
I have tried several approaches.
A) I created a backup of database on my local, then placed a copy on the server. Then I tried to restore through Server Management Studio. I get this error.

B: I also have tried copying the database. I put it in the same path as the other databases that can be read with server management studio on the server. Then, tried to get to it through server managements studio and it did not appear. So I tried to attach it. Then I received this error:

C: I have also tried opening the Database, and back up file through Server Management Studio. without success.
D: I also tried Windows and Software update at microsoft update, but no updates were recommended for Version on Server.
I'm surprised this is so hard. My original data base was created in same family of software. 2005 MS SQL Express. I could use some direct help from someone experienced with this. Am I doing it wrong or are the DB versions incompatible.
I was writing a query using both left outer join and inner join. And the query was ....
SELECT Â Â Â Â Â Â Â S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Â Â Â Â Â Â Â Production.Suppliers AS S LEFT OUTER JOIN Â Â Â Â Â Â (Production.Products AS P Â Â Â Â Â Â Â Â INNER JOIN Production.Categories AS C
[code]....
However ,the result that i got was correct.But when i did the same query using the left outer join in both the cases
i.e..
SELECT Â Â Â Â Â Â Â S.companyname AS supplier, S.country,P.productid, P.productname, P.unitprice,C.categoryname FROM Â Â Â Â Â Â Â Production.Suppliers AS S LEFT OUTER JOIN (Production.Products AS P LEFT OUTER JOIN Production.Categories AS C ON C.categoryid = P.categoryid) ON S.supplierid = P.supplierid WHERE S.country = N'Japan';
The result i got was same,i.e
supplier   country   productid   productname   unitprice   categorynameSupplier QOVFD   Japan   9   Product AOZBW   97.00   Meat/PoultrySupplier QOVFD   Japan  10   Product YHXGE   31.00   SeafoodSupplier QOVFD   Japan  74   Product BKAZJ   10.00   ProduceSupplier QWUSF   Japan   13   Product POXFU   6.00   SeafoodSupplier QWUSF   Japan   14   Product PWCJB   23.25   ProduceSupplier QWUSF   Japan   15   Product KSZOI   15.50   CondimentsSupplier XYZ   Japan   NULL   NULL   NULL   NULLSupplier XYZ   Japan   NULL   NULL   NULL   NULL
and this time also i got the same result.My question is that is there any specific reason to use inner join when join the third table and not the left outer join.
OLEDB source 1 SELECT ... ,[MANUAL DCD ID] <-- this column set to sort order = 1 ... FROM [dbo].[XLSDCI] ORDER BY [MANUAL DCD ID] ASC
OLEDB source 2 SELECT ... ,[Bo Tkt Num] <-- this column set to sort order = 1 ... FROM ....[dbo].[FFFenics] ORDER BY [Bo Tkt Num] ASC
These two tasks are followed immediately by a MERGE JOIN
All columns in source1 are ticked, all column in source2 are ticked, join key is shown above. join type is left outer join (source 1 -> source 2)
result of source1 (..dcd column) ... 4-400-8000119 4-400-8000120 4-400-8000121 4-400-8000122 <--row not joining 4-400-8000123 4-400-8000124 ...
result of source2 (..tkt num column) ... 4-400-1000118 4-400-1000119 4-400-1000120 4-400-1000121 4-400-1000122 <--row not joining 4-400-1000123 4-400-1000124 4-400-1000125 ...
All other rows are joining as expected. Why is it failing for this one row?
I'm having trouble with a multi-table JOIN statement with more than one JOIN statement.
For each order, I need to return the following: CarsID, CarModelName, MakeID, OrderDate, ProductName, Total ordered the Car Category.
The carid (primary key) and carmodelname belong to the Cars table. The makeid and orderdate belong to the OrderDetails table. The productname and carcategory belong to the Product table.
The number of rows returned should be the same as the number of rows in OrderDetails.
Why would I use a left join instead of a inner join when the columns entered within the SELECT command determine what is displayed from the query results?
I have a merge join (full outer join) task in a data flow. The left input comes from a flat file source and then a script transformation which does some custom grouping. The right input comes from an oledb source. The script transformation output is asynchronous (SynchronousInputID=0). The left input has many more rows (200,000+) than the right input (2,500). I run it from VS 2005 by right-click/execute on the data flow task. The merge join remains yellow and the task never finishes. I do see a row count above the flat file destination that reaches a certain number and seems to get stuck there. When I test with a smaller file on the left it works OK. Any suggestions?
A piece of software I wrote starting timing out on a query that left outer joins a table to a view. Both the table and view have approximately the same number of rows (about 170000).
The table has 2 very similar columns, one is a varchar(1) and another is varchar(100). Neither are included in any index and beyond the size difference, the columns have the same properties. One of the employees here uses the varchar(1) column (called miscsearch) to tag large sets of rows to perform some action on. In this case, he had set 9000 rows miscsearch value to "g". The query then should join the table and view for all rows where miscsearch is set to g in the table. This query takes at least 20 minutes to run (I stopped it at this point).
If I remove the "where" clause and join all rows in the two tables, the query completes in about 20 seconds. If set the varchar(100) column (called descrip) to "g" for the same rows set via miscsearch, the query completes in about 20 seconds.
If I force the join type to a hash join, the query completes using miscsearch in about 30 seconds.
So, this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER HASH JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
and this works:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE descrip = 'g' ORDER BY balance DESC
But this does't:
SELECT di.File_No, prevPlacements, balance,'NOT PLACED' as status FROM Info di LEFT OUTER JOIN View_PP pp ON di.ram_file_no = pp.file_no WHERE miscsearch = 'g' ORDER BY balance DESC
What should I be looking for here to understand why this is happening?
We are trying to migrate from sql 2005 to 2012. I am changing one of the implicit join to explicit join. As soon as I change the join, the number of rows returned are fewer than before.
INSERT #RIF_TEMP1 (rf1_row_no,rf1_rif, rf1_key_id_no, rf1_last_date, rf1_start_date) SELECT currow.rf0_row_no, currow.rf0_rif, currow.rf0_key_id_no, prevrow.rf0_start_date, currow.rf0_start_date FROM #RIF_TEMP0 currow LEFT JOIN #RIF_TEMP0 prevrow ON (currow.rf0_row_no = prevrow.rf0_row_no + 1)
[Code] ....
the count returned from both the queries is different.
I am not sure what am I doing wrong. The count of #RIF_TEMP0 is always 32, it never changes, but the variable @countTemp is different for both the queries.
Why does this right join return the same results as using a left (or even a full join)?There are 470 records in Account, and there are 1611 records in Contact. But any join returns 793 records.
select Contact.firstname, Contact.lastname, Account.[Account Name] from Contact right join Account on Contact.[Account Name] = Account.[Account Name] where Contact.[Account Name] = Account.[Account Name]
Is there a way to do a super-table join ie two table join with no matching criteria? I am pulling in a sheet from XL and joining to a table in SQLServer. The join should read something like €œfor every row in the sheet I need that row and a code from a table. 100 rows in the sheet merged with 10 codes from the table = 1000 result rows.
This is the simple sql (no join on the tables):
select 1.code, 2.rowdetail from tblcodes 1, tblelements 2
I read that merge joins work a lot faster than hash joins. How would you convert a hash join into a merge join? (Referring to output on Execution Plan diagrams.) THANKS
There is a table called "tblvZipCodes" that contain a zipcode of all cities, area code that are located in that zip code.
The problem I have with the inner join is that there are more than 1 cities in one zipcode code. Is there a way to just return only the 1st row and not return the rest of the rows from the tblvZipCodes in the INNER JOIN query?
Thanks..

hello, i am running mysql server 5 and i have sql syntax like this: select sales.customerid as cid, name, count(saleid) from sales inner join customers on customers.customerid=sales.customerid group by sales.customerid order by sales.customerid; it works fine and speedy. but when i change inner join to right join, in order to get all customers even there is no sale, my server locks up. note: there is about 10000 customers and 15000 sales. what can be the problem? thanks,
I have 2 tables, I will add sample data to them to help me explain...Table1(Fields: A, B)=====1,One2,Two3,ThreeTable2(Fields: A,B)=====2,deux9,neufI want to create a query that will only return data so long as the key(Field A) is on both tables, if not, return nothing. How can I dothis? I am thnking about using a 'JOIN' but not sure how to implementit...i.e: 2 would return data- but 9 would not...any help would be appreciated.
