Question

I’m interested is it possible with PL/SQL block to transfer the content of a Oracle table into text file on the Hard Drive. I need a PL/SQL block which can download the content of a table witch will be used to store log data into text file.

you can use UTL_file package for this..

you can try below type of block —

declare 
p_file util_file.file_type;
l_table <your_table_name>.ROWTYPE;
l_delimited varchar2(1) := '|';
begin
p_file:= utl_file.fopen('<file_path>','<file_name>','W');
for l_table in (select * from <your_table_name>) loop
utl_file.putline(p_file,l_table.col1||l_delimited||l_table.col2||l_delimited||l_table.col3||l_delimited||l_table.col4||l_delimited <continue with column list .........> ||chr(10));
end loop;    
utl_file.fclose_all();
end;
