how to compare 2 sql tables and show data that are in table 1 but not in table2?
Dim strSQLL As String = "Select t1.run from ML533 t1 left join portal t2 on t1.[run] = t2.[runNo] where t1.[run] <> t2.[runNo]"
Dim comm As New System.Data.SqlClient.SqlCommand(strSQLL, conn)
Dim ds1 As DataSet = New DataSet()
[code]....
i have tried google and other sites.. but still cannot find solution. maybe i post the wrong question. but i manage to do this code. but its only shows only 1 record missing, but its supposed to show 5 records that r missing.
The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too. The datagridview does show the table names in the db using the SHOW TABLES sql statment, but I'm not understanding how to get this info into the combobox instead.
i need to compare two different tables which are Enlistment and Schedulings Table . in schedulings Table , there was a columnnmae AvailableSlots wherein the AvailableSlots in every sections in every year is recorded.. in Enlistment table, i used to count the number of records that satisfy my query : "Select Count(*) as Total from Enlistment where YearLevels = '" & TextBox4.Text & "' AND Sections = '" & ComboBox1.Text & "'"Now, i need to know how many slots are taken that satisfies the query.. to know the number of students that can only be enrolled on that particular sections ..
here's my codes :
con = New OleDbConnection("Provider= Microsoft.ACE.oledb.12.0; Data Source=|DataDirectory|Enrollment System.accdb;Jet OLEDB:Database Password=jhedonghae;") Dim ewaaa As String = "Select Count(*) as Total from Enlistment where YearLevels = '" & TextBox4.Text & "' AND Sections = '" & ComboBox1.Text & "'"
Does anyone know how to delete the record then the deleted record will add to another table.let said i want to delete record from table1 ID '3', description 'monitor', Qty '2'after deleted the Qty, will auto add 2 to the Table2 Total field.[code]
-Table in database 1 has 5 fields -Table in database 2 has 15 fields
I made 2 querys that retrieve the 5 fields from the first and 5 fields from the second that are the same from the first.I need to update data in Table1 with elements present in table2 that arent in table1 without deleting elements in Table1.
i want to create a table that include a current year data and as well as previous data to be compare. here is the example of the table that i want to create: but i want to compare one of the annual data with the previous year. as example i want to compare between the data of current AR of 2007 with the current AR for 2006, Current AR of 2006 with current AR for 2005 and go on~, but i have no idea how to do it.
I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:
1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.
2) A server application does some work on some text files, periodically updating the data table.
I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.
1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?
2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

I have datagridview1 binded to data Table1 (with binding source) . This data table1 is in relation with his child data table2.When I insert new record to table1 I want to refresh datagridview1.
If I use table adapter fill method I get error.TableAdapter1.Fill(Me.DataSet1.Table1) ' error error: Cannot clear table Table1 because ForeignKeyConstraint FK_Table1Table2 enforces constraints and there are child rows in Table2.
I am trying to produce a form in VB2008 which shows data from two related database tables, and then allows the data in one of the tables to be updated. I would like to do this using a DataGridView, but I have no idea how I would go about this.
I need to get a table on my Form that has different columns from differen tables.As I call many tables by their Identity ID, I also need a way to show the information from that table.I created a query in my TableAdapter which selects information from 2 different tables. Tested it in the query builder and all was OK.I tried to put an empty DataGridView onto my Form and inserted the correct BindingSource for my Data Source.I then added a query and selected the query I created in my TableAdapter.
if it affects the run time of a program if I were to have multiple data tables as opposed to one data table with all my data in it? I am trying to minimize datagrids and just use code to access table data, in hopes that it will speed up my program. But I am ignorant if multiple tables vs 1 main table will make a difference because there will still be the same amount of overall data present in my program one way or the other....?
Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..
I am combining data from multiple tables into one table for a presentation software. I am doing a select statement and running a loop. Inside that loop I have multiple selects and I build a datatable an enter the data into the main table. There is a ton of records and it takes forever.

We have an access database that contains Version table. the same file is stored in 2 separate locations, how would i pull the information from both c:db1.mdb and \servernamedb1.mdb's table so i could compare the two?
I have one dataset with two tables and when some values from tables are changing I need somehow to change the values from table 2. Table one is conected to an SQL server. One table 1 receives a message from sql service broker it automatically reload all the information. I need in that moment to compare what I have new in table 1 and put it in table 2.

My sql database is :and on form1 objects is 5 X Textbox and 1X numericupdown I want with numericupdown value=1 then first 5 rows column name fill on the 5 textbox and so numericupdown value =2 then fill second 5 rows fill on the 5 textbox and so for all rows repeat.
I have three Tables in the MS Access database as below:
Company_Data Name|Age|Department|Salary User_Data
[Code].....
and i have a compare button on the VB form. Is there any code that can compare the Company_Data with User_Data and copy all the records not found in User_Data to Changes_Data table. When updating it should update the "updated on" Column to the current Date.
Same needs to be done in the opposite way. Compare User_Data with Company_Data and note the diff. No Need to update Salary in this case.
I need to pupulate a Grid, but i like to do like Microsoft SQL Server Management Studio, when you make a Select to a table with bounch of rows, it start show the result but in the botton still retriving data.So you can start looking the data, not like you get the data and after you get the last row you can asing to the Grid.
I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for.Is there a way to edit columns and rows manually ?This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )
