dbms-output

Im using Aqua Data Studio to debug a stored proc by scattering output statments throughout. I have a delete statement in the package which violate an integrity constraint: DELETE FROM x WHERE x.ID = an_x_with_children; My proc fails with an ORA-02292 on this line, as expected. I want to see the value of the an_x_with_children variable. So I wrap the line with outputs like so: dbms_output.put('Attempting to delete x: ' || an_x_with_children); DELETE FROM x WHERE x.ID = an_x_with_children; dbms_output.put(' Success'); And expect to see the message as the last thing in the messages console prior

This question already has an answer here: Why no output when PLSQL Anonymous block completes? [duplicate] 7 answers Printing the value of a variable in SQL Developer 8 answers I am using SQL Developer and want to output the contents of a variable to the console using DBMS_OUTPUT.PUT_LINE(). I am running the following code that adds the numbers 1 through 5 inclusive but I'm not seeing any output. SET SERVEROUTPUT ON; DECLARE n_counter NUMBER := 5; -- Substitute this variable n_sum NUMBER := 0; BEGIN WHILE n_counter != 0 LOOP n_sum := n_sum + n_counter; n_counter := n_counter -1; END LOOP; DBMS

I implemented a function that returns clob data-type, and I would like to print the result in DBMS Output . Unfortunately, I am getting ORA-06502: PL/SQL: numeric or value error and I think it is due to the size of DBMS_OUTPUT. This is the code. DECLARE TYPE tp_col_array IS TABLE OF varchar2(32767); FUNCTION my_fn ( p_in_proc_date IN varchar2) RETURN clob AS vr_output_str clob; BEGIN -- Detailed code hidden due to privacy. Sorry RETURN vr_output_str; EXCEPTION WHEN LOGIN_DENIED THEN DBMS_OUTPUT.PUT_LINE('Invalid username/password: logon denied'); RETURN 'TEST Terminated'; END my_fn; BEGIN DBMS

I have an SQL script that is called from within a shell script and takes a long time to run. It currently contains dbms_output.put_line statements at various points. The output from these print statements appear in the log files, but only once the script has completed. Is there any way to ensure that the output appears in the log file as the script is running? Not really. The way DBMS_OUTPUT works is this: Your PL/SQL block executes on the database server with no interaction with the client. So when you call PUT_LINE, it is just putting that text into a buffer in memory on the server. When

I need to debug in pl/sql to figure times of procedures, I want to use: SELECT systimestamp FROM dual INTO time_db; DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db); but I don't understand where the output goes to and how can I redirect it to a log file that will contain all the data I want to collect? DBMS_OUTPUT is not the best tool to debug, since most environments don't use it natively. If you want to capture the output of DBMS_OUTPUT however, you would simply use the DBMS_OUTPUT.get_line procedure. Here is a small example: SQL> create directory tmp as '/tmp/'; Directory created
