Hi expert,
I'm facing a problem when i try to update the database, below is my code:
Dim conn As New OleDb.OleDbConnection
Dim strSQL As OleDb.OleDbCommand
Dim ra As Integer
Dim num
conn.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;" & _
"Data Source=C:\employee.mdb"
conn.Open()
strSQL = New OleDb.OleDbCommand("Update [emp] Set e_name = '" & txtName.Text & "', city = '" & txtCity.Text & "', phone_no = '" & txtPhone.Text & "', dob = '" & txtDob.Text & "', Position = '" & txtPosition.Text & "' where e_no = 2", conn)
ra = strSQL.ExecuteNonQuery()
MessageBox.Show("Records affected" & ra)
conn.Close()
conn.Dispose()
the error message was:
System.Data.OleDb.OleDbException was unhandled
ErrorCode=-2147217900
Message="Syntax error in UPDATE statement."
Source="Microsoft Office Access Database Engine"
