When Copy A Table Into DataSet Is It Possible To Copy Its Index's As Well
Sep 22, 2009
When i copy a table into DataSet is it possible to copy its index's as well? right now i add kinda big table (250k + rows) into dataset and i need to query that DataSet table in my application, the problem is that in some quires it's getting slow.what is the right approch to solve this problem?
i am trying to copy data from a standard Dataset to a Type Dataset (XSD) of same table structure. i want to use Automapper to do that one. So how can i do that using automapper?
I need to copy all data from a Table of a Acces mdb (connected with OleDB) to a Table of a MySql DB (connected with ODBC)
I made a working solution, but it's very slow, and so I want to try other solutions to check if they can give me more performance.
The solution connecting to the mdb, using a DataReader, then for each row in Datareader I make an INSERT into the Mysql Table ( before copy I truncate the table to get it empty)
The records are more than 10K and this operation is very slow, and do be onest I need to do the same thing on other 2 tables also very big as this one.
I cannot make a direct sql insert ( as INSERT INTO A in ..... SELECT * FROM B) because the 1 DB has a OleDB conn and the other has a ODBC conn.
So I thought to try to make this operation using TableAdapters and DataSet, but I'm not able to make it working.
The problem is that the Dataset's HasChanges is false
If you need some code I can post, but what I do is following:
Connection to MDb Create OleDbTableAdapter Create DataSet
Basically i have a form with a sqldataadapter and a dataset to retrieve and process data. from within the form i call another form which i use to retrieve data given some criteria which my user enter (on the secord form i also use a sqldataadapter and dataset.my problem is this: the use can select 1 or more records from the second form which he or she wants to process and the logic is to jump back to the first form and show only those records. note: the secord form (search data form) can display any number of records

What approach would I take to copy a table from one DB system to a completely different DB system? I can get the source table into a DataTable object, but I don't know how to export it to the target DB. I want the columns to be automatically created with the same names & data type.

I am using VB.NET, Framework 3.5. I'm trying to copy in C:Temp and I do have the privileges. Or at least I used to...
I'm converting a process from VB 6.0 to VB .Net. The process copies a table from one database table to another database. In many cases they are not linked so a "Select * into Table2 from Table1" is not a solution. Also the source table may be a temporary global table that has a unique structure. The current process reads the source table into an ADODB recordset, obtains the columns attributes to create a new table, creates the new table, builds insert statements from the source table, and then inserts the rows into the new table. I'd like to take advantage of any .Net features that may be more efficient than that. Can anyone point me in the right Direction?
I have a DataTable with 20 columns and it have lot of rows. I have created a SQL table which is have the same 20 columns. Now I want to copy the complete Datatable to SQL table using VB.net 2005.

Access databse, On the main form I have a combo box select a table (1 of 50 table names), the subform pulls up the table and users can go to a specific record. Once they move from the subform, how do I capture the subform fields to another table. As the combo table selects from one table, the selected table is different, my primary table is linked by FKey in this "MergedTable" with FKey "TableName" and FKey "item" for each of the 50 tables?

Anyone know how to copy a table from one database to another? I know the statement 'INSERT INTO Table1 SELECT * FROM Table2' but I want to copy from one database to another from a server to a PC. Of course, I could do a select statement for all the records and use a loop to insert them one by one, but surely there is an easier way.
I am working with Vb.Net 2005 and sql server database.
I have a query in sql database (qryImportpatients) - it has 4 fields: prac_no, prac_eid, pat_name, pat_yr. I have a table in sql database (tblProjectpatients) - it has 5 fields: Project_ID, prac_no, prac_eid, pat_name, pat_yr.
Now on my form in VB.Net - I have a textbox (txtProjectID) which has a numeric value. I want to have a function which when called will insert all the datafrom the 4 fields from qryImportpatients to tblProjectpatients and also insert the numeric value (ProjectID) besides each record.
Currently using VB 2008 with MS Access 2003.I have Two Tables with Names - " Company_Data" & "User_Data" in which i have the following columns.....
Company_Data Name|Age|Department|Salary User_Data Name|Age|Department|Updated On
Now, Is there any code that can do the following:when i select a name in the combo box on the form (The list in the combo box is from the Name in the Company_Data table) and click update.It should copy the Details of the Record from Company_Data to User_Data with the current date in "Updated on" column. Note that the columns are not exactly Same. (Salary is not necessary in the User_Data)?
I want to know how can I possibly copy a table with multiple columns and rows into an Array or Collection in VB.NET.I want to know the best solution because I want to use the code for 2 different tables and do some comparisons, and the second table has too many records.I was wondering if in VB.NET there is something similar to Hashmap used in java and a table could look like the following

I'm working on a form that has a few data grid views that are populated from LINQ queries, no problem there it works as it should however that sorting does not work. After doing some reading its because LINQ results do not support sorting.As I have the LINQ results already is there a way of copying the results into a dataset or datatable then binding the data grid view to that so sorting will work?
I have a table that I'm trying to use as a template that I can then copy to a new page. I only got this much
Dim oWord As word.Application Dim oDoc As word.Document Dim oTable As word.Table FileCopy("C:/1535.doc", "C:/1535_1" & ".doc") oWord = New word.Application [Code] .....
So I want to get a copy of oTable then after the page break it makes a new page but I don't know how go to that page and put a copy of oTable.
I'm working with the project that require save all user personal information in one table when they login my system. The problem is too many users login my system per day ( or one user can login/out many time per day), it's very hard to manage. So, I want to add one more function which can specify one user information. My solution is create a text box and a find button to filter the user whose name in text box and copy to other table after that show that table, the problem is I don't know how to do that.
I also try the code which show below, but with that way I can't achieve my require[code]...
Another question is how can I delete all information in a table in database?
