Vb net updating database


26-Feb-2018 17:59

If I need to use Insert Command, can I use the same Data Adapter/Data Set ? Update ---how can I use the same m_da SQL that is already filled with the "select * from tbl A where [col B] = 'abc'" ? In VB6, using ADO I can loop thru the recordset,set the values of col Aand call the Update method. Item("col A") = lrow --this updates the value in memory, but not in the database l Row = l Row 1 Next Thank you. In my example, I Fill the dataset using Command Text "select * from tbl A where [col B] = 'abc'", before I update it. Fill(m_ds SQL) l Row = 0 For Each a Row In m_ds SQL. Rows() s SQL = "update tbl A set" s SQL = s SQL & (" col A = " & lrow) s SQL = s SQL & (" where [col B] = 'abc') m_da SQL. For every record in tbl A where col B = 'abc', I want to update the valuein col A. Fill(d.corp); // UPDATE foreach (Row dr in d.info) Table Adapters. Table Adapter Manager(); Table Adapter = new Table Table Adapter(); Table Adapter = new Table Table Adapter(); tm. Update All(d); Turns out that I needed to call the Fill funtion instead of the Get Data function.Is there a specific reason why my code didn't work? Command Text = s SQLEnd Withm_da SQL = New Sql Client. Select Command = "select * from tbl A where [col B] = 'abc'"m_da SQL. Sql Client Connection("connection string here") Dim da As New Sql Client. Also, don't use the prefix of "ado" for your connection name since you aren't using ado anyway, you're using ADO. Here's your code again (modified for better naming conventions and correct coding): Diim con As New Sql Client. For every record in tbl A where col B = 'abc', I want to update the value in col A. Fill(m_ds SQL) l Row = 0 For Each a Row In m_ds SQL.

OLEDB.12.0; Data Source =" data File = "C:\Users\Jimmy\Documents\Test Database.accdb" conn String = provider & data File my Connection. Open() Dim str As String str = "update [Items] set [Item] = '" & Item Txt Box.

I've got the following code, but the database doesn't seem to update on the Update All(man DS) command.

I've got the following code: Table Adapter Manager tab Adapter = new Table Adapter Manager(); tab Adapter.

Connection = db Connection; //Set the db connection here.

I then create table adapters for each table adapter reference that's inside this tab Adapter object.Do anyone know why the Update All() method of the Table Adapter Manager doesn't appear to work?
