When calling the method below, if I use the SQL in red, the Pull method populates my data correctly. But, If I use the sql in Green, I get an errror message. I have set breakpoints and un the SQL that is returned from the sql statement is green, and it returns records. What gives? Are Joins not allowed?
public void GetDiagnosisList()
{
// Connection string to SQL Server 2000
string rdaOleDbConnectString = "Provider=sqloledb; Data Source=WORKPC;Initial" +

// string SQLGet = "SELECT tblLUDiagnosis.strDiagnosisCode, tblLUDiagnosis.strDiagnosisDesc FROM tblLUDiagnosis" +// " INNER JOIN tblPatientEpisode ON tblLUDiagnosis.strDiagnosisCode = tblPatientEpisode.strPrimaryDiagnosis" +// " WHERE tblPatientEpisode.intHospitalID =" + intHospitalID;

Table 3: ID RoleID Time 1 1 09:14 2 1 09:15 1 2 09:16
Now I want all the records which belongs to RoleID 1 but if same ID is belongs to RoleID 2 than i don't want that ID.From above tables ID 1 belongs to RoleID 1 and 2 so i don't want ID 1.
I'm developing a Windows Mobile application, which is using RDA Pull for retrieving data from SQL Server 2005 database to PDA. Please, see the example:
Code Snippet
using (SqlCeEngine engine = new SqlCeEngine(connStr))
the sqlcesa30.dll cannot connect to SQL Server database.
In the sqlcesa30.log then I found following line:
Code Snippet
2007/04/17 10:43:31 Thread=1EE30 RSCB=16 Command=PULL Hr=80040E4D Login failed for user 'test'. 18456
The user 'test' is member of db_owner, db_datareader and public roles for the Demo database and in SQL Server Management Studio I'm able to login to the Demo database with using the 'test' users credentials and I'm able to run the select command on 'mytable'.
So, what's wrong? Why the sqlcesa30.dll process cannot login to the Demo database, and from another application with using the SAME connection string it works?
We find that a delete command on a table where the rows to be deleted involve an inner join between the table and a view formed with an outer join sometimes works, sometimes gives error 625.
If the delete is recoded to use the join key word instead of the = sign then it alway gives error 4425.
625 21 0 Could not retrieve row from logical page %S_PGID by RID because the entry in the offset table (%d) for that RID (%d) is less than or equal to 0. 1033 4425 16 0 Cannot specify outer join operators in a query containing joined tables. View '%.*ls' contains outer join operators. The delete with a correleted sub query instead of a join works.
Error 4425 text would imply that joins with view formed by outer joins should be avoided.
SQL Server 2000Howdy All.Is it going to be faster to join several tables together and thenselect what I need from the set or is it more efficient to select onlythose columns I need in each of the tables and then join them together?The joins are all Integer primary keys and the tables are all about thesame.I need the fastest most efficient method to extract the data as thisquery is one of the most used in the system.Thanks,Craig
Why is it that SQL joins (*=) run a little faster as opposed to ANSI joins(LEFT JOIN...)? Aren't they supposed to be almost identical?
The issue is this: we are promoting using ANSI syntax for the obvious reason (future versions of SQL Server may not support SQL Server syntax; portability, etc.)
However, the problem is the speed. What have others done about this? Do you use ANSI syntax or SQL syntax? HOw true is it that future SQL Server versions may discontinue support for the '*=" and "=*' join operators.
I have four tables which I want to return results for an advanced search function, the tables contain different data, but can be quite easily joined,
Table A Contains a Main Image, this image is displayed in the results Table B Contains an Icon, this image is displayed in the results Table C doesn't have an image in it but has a child table with a number of images associated to the table, in the UNION ALL statement I would Like to do a Join to get say the top Image from this child and print it for the row associated with table C.
Select title, description, image from tableA UNION ALL Select title, description, icon as image from tableB UNION ALL title, description, ( inner Join SELECT top(1) from imageTableC where imagetableC.FK = tableC.PK) as image from tableC
Could someone show me the syntax to do this, I have all the information printing to the screen, bar this table C image.
Im having a problem with a statement i cannot seem to get 2 left joins working at the same time 1 works fine but when i try the second join i get this error:-

Hello everyone, For the sake of simplicity let's imagin we have two tables simple tables: Categories(Id, Name) and Products(Id, CategoryId, Name). My question is how can I make a product list, filtered by category, using a Stored Producedure (SP). My objective is to have the SP receiving the list of categories we want to display, as an input parameter, using it in the SQL Statement. Something like: Procedure:ListProductsFilteredByCategory@Categories AS NVarCharSELECT [C.Name] AS CategoryName ,[P.Name] AS ProductNameFROM Products PJOIN Categories C ON C.Id = P.CategoryIdWHERE IN (@Categories); How could I make this SP work in a way that @Categories can contain an undefined number of category IDs? Best regards,DBA
Hi, I am trying to write a stored proc which returns a value to me. with the parameters I'm supplying to the stored proc, it results in a set of rows and what I need is to get the a filed value of the last selected row of this query. Do I need to write two queries for this? It is something opposite to the TOP keyword functionality. I need the one of the field values in the last row. Cud anyone help me with this??
I'm trying to replicate two very big databases with about 10 million of 4000 characters each. The publisher is SQL 2000, subscriber is SQL 7.0
The subscriber will also perform full text searches.
I'm trying to decide wheter I should use PULL or PUSH. The publisher is operating on a very low quality/speed internet connection, where the subscriber is enjoying a T1.
I seem to be missing something. I'm trying to pull a subscription from SQL Server 2000. (To a desktop SQL 2000 install <msde i guess>) The general error I keep running into is When creating the subscription...
"Error 15004: Name cannot be NULL"
I cannot figure out where this problem originates. I'm running the SQL Service account and Executive under a domain account. (same one on both machines)
Does anyone know where I'm missing the Permissions for the subscription?
Please impart any Replication suggestions you have. Don't hold back....
I want to use window script program to execute a pull subscription installed on SQL 2005 express edition. Because it free for downloand. is there a script that can call an existing pull subscription execution.
I am trying to pull the last three entries from a table in my database but I am having trouble writing the correct query. The database has multiple entries for each item in my database but I want to pull just the last three for each item. I have tried the TOP function with the items ordered in descending order but that only works when I define each item seperatley. I need to know how to pull the last three entries for every item I have in the table.
Hello, in my scenerio i am pulling a table from msde to my ppc and then i want to insert a new record to my local table but when i try to do that i faced with an index paradox forexample: if i pulled a table with record index 1 then i am triying to insert a new record at local but at local it tries to insert index 1 again so i can't finish my operation. My primariy index is seed 1 also. How can i achieve my goal?
I am new to SQL Mobile programming. I am using SQL Server 2005 Mobile and SQL Express. I have a mobile windows application + .sdf file in the PDA. When i try to pull the table the first time, the table is successfully retrieved to PDA. When i try to pull the table again, i get the following error:
"An unexpected error has occured in TestDb.exe. Select quit and then restart this program, or sleect details for more information.
A duplicate value cannot be inserted into aunique index. [table Name=_sysRDASubscriptions, constraint name=c_LocalTableName] "
The above message indicates, that the table is existing in "_sysRDASubscriptions" table.
I tried dropping the table using SQL Explorer in PDA, but it didn't work out.
I am not sure of how to drop the existing table from the database programatically, and if I drop the table from the database, will this be cleared.
Please help me in resolving this issue. I am in desperate need of an urgent solution for this.
I created a sample test application to implement RDA, after I made all required configuration, I got the following exception after call rda.pull() :
{ Error # 1 of 1 Error Code: -2147024809 Message : An error has occurred on the computer running IIS. Try restarting the IIS server. Minor sqlError.: 28022 Source : Microsoft SQL Server 2005 Mobile Edition}
I have followed the technical artical "Remote Data Access Synchronization with SQL Server 2005 Compact Edition and Visual Basic.NET" to create a sample application.
But when I run debug mode and get an exception unexpected as following as doing rad.pull :
Immediate Window:

Dears, I'm trying to set up a rda connection through the pocket pc emulator (standalone version 1.0) and my laptop which runs Windows Vista Home Premium. To start up the rda I first need to connect from my emulated device to my laptop which runs IIS 7.0 (complete installation with compatibility toward IIE 6.0). Connection to http://localhost from my laptop is working fine.
I start the emulator (Pocket Pc with Windows Professional) and cradle the emulated device. Connection starts and I'm able to browse from my pc the content of the emulated device or to synchronize it. Then I run Internet Explorer on the emulator and try to connect to http://mycomputername (correct) but I receive a message which says that it cannot connect to the page I was looking for because connection was lost. Any suggestion on how to solve this issue? Kind regards and many thanks in advance Cristian
It seems that now I can connect to http://mycomputername and I'm able to browse the net with my pocket pc emulator. Anyway when I'm attempting to connect to htpp://mycomputername/subfolder/sqlcesa30.dll (the path is correct, I receive the following error message: "The page cannot be displayed or downloaded because the connection was lost. Check the connection and try later"..which is the same message I've been receiving before)
i have one publisher with one pull subscription. when i make any change in publisher, that change is propegated to subscriber, but when i make any change in subscription, the change is not reflected. i have tried a lot of options but no one worked. please help me.
RDA.Pull method is not doing anything for me from a VSTO 2005 Outlook addin project. I have IIS & SQL Server 2005 running on my develpoment pc. I am using Integrated Windows Auth for vdir. It just stops execution at the line of code that calls RDA.Pull & doesnt return any tables nor throws an error. I have no idea where I am going wrong. I have tried using table names that dont exist in the .sdf too.

Can someone please help me with this? I need a query that will pull clients that made payments last year but not this year. I need the query to use date parameters so I can select any date range for the past year and the current year. I have listed the tables and fields that might be needed: I'm hoping to do this without temp tables. Date range is based on the tblPaymentReceipts.PaymentDate tblClients, ClientID tblPayment, PmtID, ClientID, Paystartdate, Paygroup tblPaymentReceipts, PmtRcptID, PmtID,CleintID,PaymentDate,PaymentAmount
Hi, Writing a report that displays total hours, etc for each day in a given month and I'm having trouble comking up w/ an elegant solution. Tables are set up like this: table1 (id, start_date,end_date,submitter) table2( id,table1_id,start_time,end_time, etc) Each record in table2 is a child to a parent record in table1 and there may be multiple children for each parent. The "start_time" and "end_time" fields are datatype "datetime" and are stored with actual times (not 12:00:00 AM"). I need the report to display the values for each day in a gridview, etc so I can act upon them from the "RowDataBound" sub (more math, etc). The problem that I am running into is that for records that have multiple children for a given day, I need to sum those results and display the summed data as a single row within the GV - can't seem to work that out - I keep getting every child record displaying as its own row in the GV. Any thoughts? I'm sure it's probably fairly simple but I am still a beginner...thanks as always
I want to pull ALL users from Table1 and include information that person may have in Table2. As of now, it is only including users that have something in Table2. How do I include everyone? Thanks
hi, I want to setup transactional replication(PULL) between 2 servers . can anyone guide me with the steps involved while performaing a Pull replication from server1 to server2. Any help appreciated.
When doing a pull subscription where the schema is also replicated, the snapshot fails with the message " The process could not create the file [machine name]D$MSSQL7ReplDataunc[Publisher Name]DateTable Name.sch
There is an OS Error Code of 5 saying Acces is denied.
The file mentioned above is created, so perhaps it fails trying to create a file for the next table.
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
I have a problem creating a pull merge subscription on a server that's outside of our firewall. All standard ports are blocked so MS UNC connections are not possible which SQL 2000 uses by default when creating a subscription. Equally FTP is out = insecure.
I found a procedure to that said create the snapshot of the publication, create a backup of the published database, restore that backup to the remote server as a subscription db and then sync using merge. Didn't work, failed (several times).
Can anyone enlighten me as to what I'm doing wrong or indeed if I'm doing anything correctly!
I can create a remote desktop (Term Server) connection to the remote and another back to the publisher (from the subscriber's desktop) and both connections are using SSH tunnels. SQL Server uses a non standard port to communicate over the firewall. The remote server sits behind another firewall/router with port redirection to it's private address. Each server has the other registered and there are no comms problems and indeed there are other replicated dbs between them.
Both servers are win 2003 and the remote (subscriber) is R2 version, both with SQL 2000 Server Std patched up to SP3. (if this has any bearing on the solution which I presume there is)
Many thanks for listening and I hope a few of you can answer as well
I need to copy a large amount of data from one table and insert it into another table.
The design of the destination table is exactly the same as the source table except for the fact that it has one extra field. Can I copy; in a single SQL statement; all rows in one table (that match given criteria) into another table allowing for the extra field?
