When Aqua Data Studio is launched, the main application window and toolbars appear, with the Schema or Files Browser in focus depending on what was being viewed when the application was last exited. Most of what Aqua Data Studio is capable of can be found in the main application toolbar and menus. If you need to customize the output from your queries, it is better to use tools such as Oracle Reports than DBMS_OUTPUT and SQL*Plus.Below is a list of all the available menus within the main application toolbar. CAUTIONĭBMS_OUTPUT is designed to be used primarily for debbuging. This usually is not a problem when DBMS_OUTPUT is used for debugging. This means that the output will be echoed to the screen when the block has finished and not during execution of the block. With SERVEROUTPUT on, SQL*Plus will call DBMS_OUTPUT.GET_LINES after the PL/SQL block has completed. Optionally, you can specify size with SET SERVEROUTPUT ON SIZE buffer_size where beffer_size will be used as the initial size of the buffer (the argument to DBMS_OUTPUT.ENABLE). The SQL*Plus command SET SERVEROUTPUT ON implicitly calls, which sets up the internal buffer. With this option, SQL*Plus will automatically call DBMS_OUTPUT.GET_LINES when a PL/SQL block concludes and prints the results, if any, to the screen. In addition, some third-party products (SQL-Station included) have an option that allows the display of DBMS_OUTPUT data. Having said that, how can we use DBMS_OUTPUT for printing? SQL*Plus, SQL*DBA, and Manager ll have an option known as SERVEROUTPUT. Essentially, it implements merely a first in, first out data structure. The DBMS_OUTPUT package itself does not contain any mechanism for printing. If DISABLE is called, the contents of the buffer are purged, and subsequent calls to PUT and PUT_LINE do not affect. If DISABLE is called, the contents of the buffer are their structure dictates. They are stored in their internal format, taking up as much space in the buffer as their structure dictates. Later, arguments to PUT or PUT_LINE will be placed in this buffer. The default size is 20,000 bytes, and the maximum size is 1,000,000 bytes. Where buffer_size is the initial size of the internal buffer, in bytes. The syntax for the PUT and PUT_LINE calls are: ENABLE and DISABLE control of the buffer. ![]() The GET routines are GET_LINE and GET_LINES. The PUT routines in the package are PUT, PUT_LINE, and NEW_LINE. There is also an ENABLE procedure that sets the size of the buffer. A PUT operation takes its argument and places it into an internal buffer for storage.Ī GET operation reads from this buffer and returns the contents as an argument to the procedure. Two basic operations, GET and PUT, are implemented through procedures in the package. This means that any Oracle user can call the routines in DBMS_OUTPUT without having to prefix the package name with SYS. The script which creates DBMS_OUTPUT grants the EXECUTE permission on the package to the PUBLIC, and creates a public synonym for it. ![]() DBMS_OUTPUT package in Oracle, like other DBMS packages, is owned by the Oracle user SYS. In this article, we will examine the DBMS_OUTPUT package in some detail. ![]()
