THanks again

But this command doesn't execute :
My base is in a library called "revue" so for a normal request I type :
$sql= 'select * from revue.My_table "
$tab=executeSQL($sql)
Where execute Sql is a function that return a table tht contains the sql result.
To test your solution I typed :
$sql= "select column_name
from all_tab_columns
where table_name = 'revue.user'";
And it doesnt works : The error sais that "ALL_TAB_COLUMNS doesnt exists in revue"
Thans for your patience
