I have 2 databases.
-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 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'm creating my first software but I have a problem: I have two tables in my database and I managed to transfer data from table1 to table2. How can I just insert specific rows from table1 to table2. I don't want to copy all the data in table1 to table2; I just want to copy the selected rows.
Here's my code:[code...]
I have a listbox which has a sourcebinding which is borrow and I only want the selected items single row to be transferred to my table returns but I don't know how to do it. Whenever I click the button, everything in table borrow will be copied to table returns.
i am trying to write code to insert selected rows from Table1 to Table2 ,, so i find code do that with DataGradView and i try to Modifies it to work with Multi records " Without DataGradView"

How i can import row from TABLE1 to TABLE2 without primary keyfield or adding correct value to primary key
i tried with two different codes, but result is same, it says: "In the column "Key"a constraint on the uniqueness.[code]...
I have two tables:
table1
case_no flow result
tc_1 001 pass
tc_1 002 pass
tc_1 003 pass
tc_2 001 pass
tc_2 002 fail
tc_2 003 pass
table2"
case_no result
tc_1 pass
tc_2 fail
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..
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]

View 3 RepliesI have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

Any thoughts on this? Btw, this is my first time using a datarow, and I've recently been studying how to use ADO.net.

I'm trying to utilize two tables with SQLReader but it's not working as planned.This is a simple explanation:
Table1 has columns c1 and c2, both integer.
Table2 has column data that is string (numeric with hyphen separators).
A typical record has this: : 20123-456-9834-167
The user inputs two integer values in variables uf2 and uf3.I want to get records from table1 that match the criteria:
1. Column c2 equals uf2.
2. A table2 record is found that:
a. has "-" + c1 at the end. (e.g. If c1 value is 167, the record above matches.)
b. has "-" + uf3 elsewhere in the record. (e.g. If uf3 value is 456, the record above matches.)
There is no "relationship" between the two tables.
The pertinent SQL code I have tried is similar to this:
dim strQuery as string = "SELECT c1, c2, data FROM table1, table2 WHERE " & _
"c2 = @f2 AND data LIKE '%-' + c1 AND " & _[code].....
I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.

View 10 RepliesI have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.

in my every form i use update button to update values in a raw,
Now my query is that:- for doing so right now i have two option
1) UPDATE Table1 SET Column1 = Value1, Column2 = Value2 WHERE Some_Column = Some_Value but in this if i have many colom it will be a long process as in some table i have more than 50 coloms.
so i found a second option which is, first delete the row and then again insert the values but in this case it changes its row no which in some case not good for my project.
so i want to know is there any way to update * . or is there any short way to update similar to delete and insert.

I am working on a timekeeping application using Visual Basic 2008 Express and Access 2000.The database has two identical tables, each with 50 identical fields. Only the table names are different as are the input control names on the Windows form. The queries are also identical except for the query name and the reference to the table name in the "INSERT INTO" statement.
The sub procedure in Visual Basic for Week 1 works perfectly and inserts the record. The sub procedure for Week 2 runs through all commands and parameters but doesn't update the table.I have looked at every line of code, every parameter and every entry in the query and find nothing wrong. I run the query from within Access and it works fine.
Heres where I find an inconsistency that baffles me.the last lines of code in both sub procedures are:
objData.OpenConnection()
objData.Command.ExecuteNonQuery()
intRowsAffected = objData.Command.ExecuteNonQuery
[code]....
I set breakpoints at each line an the procedure that works stops at each of the six lines of code, the procedure that doesn't work gets to the 3rd line(in italics) and then exits the procedure with no error message and no indication as to why the record was not saved.
