Good Mornig my fryends, my english is more or less but....
I need help, I need commit transacions between TWO databases maintenance referencial integrity.
example:(sql server 2000)
DATABASE 1 <------------------ODBC/BDE(Delphi 5.0)--------DATABASE 2
TABLE 1 TABLE 2
*colunm a <--Query(ODBC(SELECT(*),UPDATE(set),DELETE)----*colunm b
colunm a1 colunm b1
Enforce relationship for INSERT and UPDATES
Cascade Updated related Fields

Hi, anyone could help me on how to do the inner join of two table from two different database. Below is my scripts: Dim sqlconnection1 As New SqlConnection(ConfigurationSettings.AppSettings("appDSN")) Dim sqlCommand2 As New SqlCommand("", SqlConnection1) Dim sqlconnection2 As New SqlConnection(ConfigurationSettings.AppSettings("smDSN")) Dim sqlCommandSM2 as new sqlCommand("", sqlconnectionSM2) Sub Page_Load(Source as Object, E as EventArgs) sqlCommand2.CommandText = "Select * from invitation inner join Guest on invitation.guestid = Guest.Guestid inner join Department on Department.departmentcode = Guest.deptCode where eventcode = '" & ecode & "'" sqlconnection1.Open() ............................ The invitation table is from SqlConnection1 and the Department table is from the sqlconnection2. How to do this . Pls .. pls help me. Ann123
I have an sql 7.0 server. I need to run a query on a remote oracle server then take that output and inner join it with another table on the remote oracle server... then I need to put it a table in a database on my sql server... Anyone know how to do it? Help would be greatly appreciated...
When you make a join, it may look something like this:
SELECT Products.ProductName from Products, Categories WHERE Categories.CategoryName = 'Seafood' AND Products.CategoryID = Categories.CategoryID
In this query you use 'Products.CategoryID = Categories.CategoryID' to give the relation between the two tables. But if you already added the relationships to your database, this should be known.
My question is, why is it necessary to add the relation in the query when the relationships are already in the database? Is it somehow possible to ommit the relation in the query and make use of the relationships in the database.
Hi I am using the databse diagrammer to create a database. creating the tables and fields is no problem but there seems to be a lack of choice with joins and I cannot see how to set cardinality. any help appreciated.
I have a very simple Join Query like Select A, B , C From Database1.dbo.Table1 Inner Join Database2.dbo.Table2
Now problem is that Database name for the project freuqently changes though Table1 and Table2 names remain constant. How can I store Datbase name at a central place in a table or as a constant so that I can use them in above query. It will allow me to change them at one place without making changes in all the sps where they are used
Hi,I have two databases on the same server: COMU0002 and 2007DUand two tables: tecnicos on COMU0002 and telf_cli ON 2007DUBeing on COMU0002 this query doesn't work:SELECT * FROM tecnicosLEFT JOIN 2007DU.dbo.telf_cliON ...The error says: INCORRECT SYNTAX NEAR '2007'Even this query being on 2007DU fails on management studio:SELECT * FROM 2007DU.dbo.telf_clibut SELECT * FROM telf_cli works okAny ideas?Thank you!
Just trying to select a set of Articles from a SQL Server Database. The Articles all have a Category ID which is stored in another table (as an Article could be in more than one Category). I want to select the Top 3 Articles in a Category. At the moment I have as my SQL;
"SELECT TOP 3 f.ArticleID, f.Heading, f.Summary, f.WrittenDate, f.ArticleURL FROM feedTable f LEFT JOIN Categories c ON f.ArticleID = c.ArticleID WHERE c.CategoryID=" + CategoryID + " AND c.ArticleID<>" + id + " ORDER BY c.CategoryID"
Which seems to work to an extent in that I do get three articles in the same Category appearing. However, there are sometimes duplicates appearing, so I need to incorporate a DISTINCT clause to the above. I'm not sure where to put this in though. Any ideas?
I need to extract from a database of an association, the name of the associate and its last paid share, but after a day trying I simply cannot extract that data.
The table senhas represents the shares, the table associados the associate data and senhas_associados, represents the shares paid by an associate, as it was a many to many relationship.
To query this, I'm trying to query the share with the maximum id (senha) which is in seassoc_senha_id in senhas_associados which represents a paid share.
Here's what I've tried so far:
Firstly, I've tried this statement, the output is the required, but it doesn't show associates who haven't paid any share which is needed (no records in senhas_associados):
SELECT assoc_nome, senha_desig FROM associados, senhas, senhas_associados WHERE assoc_id = seassoc_assoc_id AND seassoc_senha_id = senha_id AND seassoc_senha_id IN (SELECT max(seassoc_senha_id) FROM senhas, senhas_associados WHERE seassoc_senha_id = senha_id AND seassoc_assoc_id = assoc_id)
the output: assoc_nome senha_desig Carlos CostaMaio Rodrigo Abril
I've even tried adding this: SELECT assoc_nome, senha_desig FROM associados, senhas, senhas_associados WHERE assoc_id = seassoc_assoc_id AND seassoc_senha_id = senha_id AND seassoc_senha_id IN (SELECT max(seassoc_senha_id) FROM senhas, senhas_associados WHERE seassoc_senha_id = senha_id AND seassoc_assoc_id = assoc_id) OR senha_desig is null
To no avail, the output was the same.
Then, I've changed the "tactic" and went to left join: SELECT assoc_nome, senha_desig FROM associados LEFT JOIN senhas_associados ON associados.assoc_id = senhas_associados.seassoc_assoc_id LEFT JOIN senhas ON senhas.senha_id = senhas_associados.seassoc_senha_id
The output: assoc_nome senha_desig Carlos CostaAbril Carlos CostaJaneiro Carlos CostaFevereiro Carlos CostaMaio Rodrigo Janeiro Rodrigo Fevereiro Rodrigo Abril Pedro SoaresNULL
Now it shows NULL's, but I can't find where to put the max function.
I've attached the relational model of the involved tables.
I have two databases with different collation sequences, let them be called A (SQL_Latin1_General_CI_AS) and B (Latin1_General_CI_AS). Now I need to join between the two (including through temp tables with server collation being Latin1_General_CI_AS). In order to get rid of the errors when trying to do so I changed all my statements in the WHERE and ON clauses to
If I were to change the collation of the character typed columns in database A to the one in database B, would it make any difference in terms of performance, or would it just be a useless exercise? Just asking because many of those columns are part of a primary or foreign key that would need to first be dropped and then recreated after changing the collation, and I'd prefer to save myself the effort of writing scripts to do so if the answer is NO.
BTW, I tried to change the database's collation sequence, but that leaves the collation of the columns unchanged.
I have a XML data passed on to the stored proc in the following format, and within the stored proc I am accessing the data of xml using the nodes() method
Here is an example of what i am doing
DECLARE @Participants XML SET @Participants = '<ArrayOfEmployees xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema"> <Employees EmpID="1" EmpName="abcd" /> <Employees EmpID="2" EmpName="efgh" /> </ArrayOfEmployees >'
SELECT Participants.Node.value('@EmpID', 'INT') AS EmployeeID, Participants.Node.value('@EmpName', 'VARCHAR(50)') AS EmployeeName FROM @Participants.nodes('/ArrayOfEmployees /Employees ') Participants (Node)
I have a database column that stores a comma delimited list of foreignkeys. Would someone show me how to do a join using the values from alist stored within a record?For example, a record in tbl_cds.genre_id might have a value of "2,5, 6" corresponding to genre_ids 2 , 5 and 6. I want to jointbl_cds.genre_id to tbl_genre.genre_id using the values in that datafield.It seems I need a loop like this:SELECT * FROM tbl_cdsWHEREBegin Looptbl_cds.genre_id[i] = tbl_genre.genre_idEnd Loop.Would someone give me the correct syntax?Is there an alternative method that would create less overhead?Sorry for such a novice post.
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
