  • oracle 11g alias to query
    H hadad

    When migrating from oracle 10g to 11g, I've a stored procedure with a syntax like:

    select * from table1
    union
    select t,y from
    (select * from table2)aliasQuery
    where (select max(t)from (select t from table 3 where table3. t=aliasQuery.t)

    query works well with 10g but 11g returns error that aliasQuery not defined

    may be this syntax no longer supported in 11g or here is some database missing configurations

    Thanks

  • Microsoft sync framework
    H hadad

    I've got a central SQL server database. My solution has a WCF service responsible for synchronizing data with clients running SQL Server or SQL Server Express. The service uses Microsoft Sync Framework and it works well, but the Sync Framework requires a direct connection to my client's server, and clients that are running SQL Server Express may not have a static IP address to let my application locate them. How can I overcome this problem? Does Sync Framework have an intermediate service that can exchange datasets of changes on both server and client? Or can I use Sync Framework to get datasets of changes?

  • mark rows as deleted or updated befor loading them in a dataset
    H hadad

    I've tried the xml to let me choose an intermediate method to tell the dataset the state of rows but it will be more efficient if it loads the data directly but If it does, also, How can I tell the row state? this data set will be transferred to a client where another adapter will update the client database so the dataset must tell the state of the rows which I cant do when loading the data because the column which tell the state is invented by my sql script and it does not belong to table so the data set will trait it as a normal column.

  • mark rows as deleted or updated befor loading them in a dataset
    H hadad

    I select the modified data from the sql server as a xml I've added an attribute to each row to tell me its state when I load this file to a dataset it does not read the stated it marks all rows as Added by default so if I want to change the state I have to loop over the table and change the rowstate property my question is Can I change the state when the data set loads the xml file or I have to loop over the table after population?

  • mark rows as deleted or updated befor loading them in a dataset
    H hadad

    Hello, I'm developping a sync solution enables filtering but is there any way to load the changes form the source database into a dataset and mark the deleted or updated rows to transfer this dataset to client and update its data? I've tryied to use the Microsoft Sync Framework but it does not allow filtering even if I use a custom provider because in my scenariro I want to sync a subset of the data on the server with a client and vice versa sync framework depends on primary key only which not acceptable here because when deleting or updating rows these rows may deletetd for another user in the source database the primary key in the client will not be the same as the server this is because I want to select the changes as xml and populate the dataset soit can mark the deleted rows and updated .. ctc
