Toad Data Point: System.OutOfMemoryException

Toad Data Point
1

Hi toad-data-point community,

I have got a System.OutOfMemoryException when trying to create a MaterializedView with 2,500,000 records (and the software crashed). See below for details.

I am using Toad Data Point 3.4.0.2038, base edition.

Does anyone know a solution?

Thanks in advance.

Thank you for reporting the issue.

I created QAT -2691 to track it.

You can avoid the issue with the following way around

  1. Add to your query where clause the following condition ROWNUM < 2 that limit the number of return rows.
  2. Fill out the Create Materialized View Form
  3. Go to Sql Script press Open script in editor button. Don’t press Executed button.
  4. In the SQL Editor remove ROWNUM < 2 condition and
  5. Execute the CREATE MATERIALIZED VIEW statement.
    It should help you

Hi Aleksey,

Thanks a lot; your work-around works!

I guess the way the Create Materialized View Form works causes the problem?

Entering and running the sql-statement Create Materialized View, without adding/deleting the Rownum<2 statement, works well.

Thanks for your help.

I mean:

Entering and running the sql-statement Create Materialized View, without adding/deleting the Rownum<2 statement, STRAIGHT INTO THE SQL- EDITOR works well.
