Tracing the Bind Values

Created a simple example of how you can isolate and trace the bind variables for the records inserted and understand what to look for in the trace file.

The table here consists of 3 columns. A varchar2, number and timestamp.

The jdev 11113 workspace for this example is here.

When running the application, this following results are displayed:

Open the trace file I can see the following:

Here you can see the first insert query references "CURSOR #8" that will bind to "BINDS #8:" which shows the binding values:

value="test_string_0.8433509446104999"
value=0
value=

Timestamp is in hex format. You will to convert that yourself to find the value.
