How to execute sets of DDL Statements in 1 command?

Question

Hi All,
I've been trying to look for a way to run a set of DDL statements. I normally have text files with DDL Statements on it. So what I do is load the contents of this text file into a Textbox and then set the Textbox.Text as the CommandText of my command object. Unfortunately I get errors.
Here's my code...
    Private Sub btnLoadFile_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim OpenDiag As New OpenFileDialog
        Dim txtReader As StreamReader
        OpenDiag.ShowDialog()
        If OpenDiag.FileName <> "" Then
            txtReader = File.OpenText(OpenDiag.FileName)
            CommandTextBox.Text = txtReader.ReadToEnd
        End If
    End Sub
    Private Sub btnExecute_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
        Dim myConn As New OracleConnection(My.Settings.ConnectionString)
        Dim myComm As New OracleCommand(CommandTextBox.Text, myConn)
        Try
            myConn.Open()
            myComm.ExecuteNonQuery()
            myConn.Close()
        Catch ex As OracleException
            MessageBox.Show(ex.Code & ": " & ex.Message)
        End Try
    End SubThe errors that I get are
"ORA-00900: Invalid SQL Statement"
- Not sure how I get this but I noticed that if i had remarks/comments in my text file, this is the error that i get. Although i don't get this error if i execute in SQL Plus.
"ORA-00911: Invalid Character"
- after removing the remarks/comments, i get this error. i tried removing the semi-colon ";" then it works okay if i'm running 1 DDL statement in my file.. but if i my file contains to DDL statements for example, then i get the this error "ORA-00922: Missing or Invalid Options".
can anyone help me with this?
thanks.

Answer 1

yes. i have BEGIN and END in their corresponding places.
i found out that removing linefeeds and semi-colons somehow fixes the problem for DDL statements. also, if i use a RichTextBox and uses its RichTextBox.LoadFile(filename, RichTextBoxStreamType.PlainText) instead of the File.OpenText(filename), it works fine as well. although its not something i would want. so what i did was to create a PL/SQL Anonymous Block instead. this too works if i use a RichTextBox.LoadFile instead of a textbox. but i'm using these controls to see the contents. eventually i will need to use a variable to store the contents of the file and i'm worried that it won't work with it.
unfortunately it doesn't work when i use a string. i'm guessing because of the linefeeds and semi-colons are still there.
