Need help Updating SQL Server Express DB from c# :(


Posted on 16th Feb 2014 07:03 pm by admin

Please can anyone help with:-
1 How to sructure the strSelect statement.
2 How to instruct the cn, da, cb, tb etc to go and get on with it.

Extra info: gl_Dataset.ds is a dataset that is in an object that is created in the forms designer.cs
and is then global to all code on this form. This setup works because I can read and display the data.
colErrByUserID is not PK but all columns in table were selected when gl_Dataset.ds was created.


private void btnSaveAllChangesMadeToAllLogsSoFar_Click(object sender, EventArgs e)
{
string strSelect = "UPDATE INTO dbo.tblQLs WHERE colErrByUserID = '" +
LoginForm.gb_strUserID + "' ";

SqlConnection cn = new SqlConnection(LoginForm.gb_strConnection);
SqlDataAdapter daTblQLs = new SqlDataAdapter(strSelect, LoginForm.gb_strConnection);
SqlCommandBuilder cb = new SqlCommandBuilder(daTblQLs);

cb.GetUpdateCommand();
daTblQLs.Update(gl_Dataset.ds, "tblQLs");

cn.Close();
}

Thank you for your help.
