Returns the textual message associated with the current LastServerErr
property of the specified object. Not available at design time and read-only at run time.
error_text = orasession.LastServerErrText error_text = oradatabase.LastServerErrText
String
The returned value indicates one of three possible states:
If Null
is returned, an Oracle Call Interface (OCI) database function has not returned an error since the most recent LastServerErrReset
property.
If a non-Null
value is returned, an OCI function has returned an error code; the returned string is the associated message.
If the message is empty, then no additional information was available.
This example demonstrates the use of the CreateDynaset
method and the LastServerErr
and LastServerErrText
properties to determine whether an Oracle error has occurred and to display the error message. Copy and paste this code into the definition section of a form. Then, press F5.
Sub Form_Load () 'Declare variables as OLE Objects. Dim OraSession As OraSession Dim OraDatabase As OraDatabase Dim OraDynaset As OraDynaset 'Create the OraSession Object. Set OraSession = CreateObject("OracleInProcServer.XOraSession") 'Set up an error handler. On Error GoTo errhandler 'Create the OraDatabase Object by opening a connection to Oracle. Set OraDatabase = OraSession.OpenDatabase("ExampleDb", "scott/tiger", 0&) 'Attempt to Create the OraDynaset Object. 'Notice that the FROM keyword is missing from the SQL statement.
