Binding problem when using NVL function

Question

Hello.
I have a problem with my ADF application (11.1.2.1).
I use VO with a query (database view) - pivot table.
If i use where clause like table.attr = :p_attr, everything works ok.
If i use where clause like table.attr = NVL (:p_attr, table.attr) and put a value in :p_attr (executeWithParam) , query executes as if there is a null value.
Debug console shows:
Binding null of type 12 for "p_attr".
Query with NVL works ok in sqldeveloper.
But in jdev, as if the table attribute isn't bind to bind variable.
If a just remove NVL function, it works.
Any idea?
Thanks.
Regards

Answer 1

Hello.
I enter 50 in p_depart parameter and click "ExecuteWithParams". Query is executed and shows records (pivot table).
But if i look at the log window i see that an empty query was executed first.
<OracleSQLBuilderImpl> <bindParamValue> [427] Binding null of type 12 for "p_depart"
<OracleSQLBuilderImpl> <bindParamValue> [428] Binding null of type 12 for "p_job"
<OracleSQLBuilderImpl> <bindParamValue> [429] Binding null of type 12 for "p_hire_od"
<OracleSQLBuilderImpl> <bindParamValue> [430] Binding null of type 12 for "p_hire_do"
Then, it is autoexecuted for the second time with parameter set to the value i inserted.
<OracleSQLBuilderImpl> <bindParamValue> [470] Binding param "p_depart": 50
<OracleSQLBuilderImpl> <bindParamValue> [471] Binding null of type 12 for "p_job"
<OracleSQLBuilderImpl> <bindParamValue> [472] Binding null of type 12 for "p_hire_od"
<OracleSQLBuilderImpl> <bindParamValue> [473] Binding null of type 12 for "p_hire_do"
The same happens in our query. But ours is much more complex and it takes a lot of time to first execute "empty" query and then with inserted parameter.
We cannot use it.
It looks like bug.
