Sql developer: question about exporting data

Question

Hi,
we're recently working with sql-developer. i've got a question about how we can export query results to txt/csv files for use in other applications.
First a problem: if we start a query that looks like this:
select * from
select * from A where start_date = &date
) a,
select * from B where start_date = &date
) b
where a.name = b.name
Sql-developer asks twice to input a value for the variable 'date', although it's the same variable and it's supposed to have the same value.
We solve this by making a script:
first we define the variable, then we put the query.
When we start the script, the query runs ok and sql developer asks to input the value for the variable once.
But now the result of the query is shown in the script output. The script output seems to be limited in number of lines and difficult to export.
So my question is: what's the best way to export query results to txt/csv files, avoiding the problem mentioned above?
i hope there is a solution where we can use a single query or script.
Thanks in advance!

Answer 1

Using bind variables like ":date" should solve the problem of being asked twice for the same thing.
Executing the query normally (F9), gives you the export options you require through the context menu inside the Results grid.
