PL/SQL Block - available online in file 'sample2' Input Table SQL> SELECT ename, empno, sal FROM emp ORDER BY sal DESC The following example uses a cursor to select the five highest paid employees from the emp table. Output Table SQL> SELECT * FROM temp ORDER BY col1 INSERT INTO temp VALUES (i, x, 'i is odd') INSERT INTO temp VALUES (i, x, 'i is even') PL/SQL Block - available online in file 'sample1' Which string is inserted depends on the value of the loop index. The values of a loop index, counter variable, and either of two character strings are inserted. The following example uses a simple FOR loop to insert ten rows into a database table. To run the scripts, invoke SQL*Plus, then issue the following commands: SQL> START exampbld The second script loads (or reloads) the database tables. The first script builds the database tables processed by the sample programs.
You can find these scripts in the PL/SQL demo directory. You do that by running two SQL*Plus scripts, exampbld and examplod, which are supplied with PL/SQL. However, the Pro*C examples expect you to use the scott/tiger account.īefore trying the samples, you must create some database tables, then load the tables with data. You can experiment with the samples from any Oracle account. You run some samples interactively from SQL*Plus, others from Pro*C programs. "Passing Parameters to a Cursor FOR Loop" "Understanding the Main Features of PL/SQL" Here is a list of the files and their locations in this guide: Filename For the location of the directory, see the Oracle installation or user's guide for your system. You can find the online files in the PL/SQL demo directory. So, they are preceded by the following comment: - available online in file '' Calling a Stored Procedure Running the ProgramsĪll the sample programs in this appendix and several others throughout this guide are available online. This appendix discusses the following topics: Running the Programs Sample 1. The sample programs illustrate several important PL/SQL concepts and features. I hope one of the (last two) examples suits the requirements for your script.This appendix provides several PL/SQL programs to guide you in writing your own. Here the outer loop finishes its execution without being affected by the broken inner one.
To not break the outer loop, a sub-routine holding the inner loop and being called ( call) from the outer one is required to hide the code block context of the outer loop from the goto break-up method: off The script below breaks the inner loop when a certain condition is net.
You will notice that the inner loop finishes execution before the outer one is broken. The result of the check is transferred to the outer loop using a variable FLAG: off The batch file here breaks the outer loop when the a certain condition in the inner loop is met. The following code snippet breaks both loops upon a certain condition is met: offĪs you can see, execution of the loop construct is interrupted immediately at a certain point. You can easily reproduce that when you increase the end value 5 to a huge number like 1000000.īut now let us concentrate on nested loops (two in each example): Note that the loop actually completes the counting internally, but no more commands are executed. The example below breaks the loop depending on its loop counter value: offĪlthough the loop is specified to count up to 5, the output is: 0 So let me elaborate on that.īreaking a single for loop is simple: put goto :STOP into the loop and the label :STOP in the line following the loop structure.
I do not exactly understand what you are trying to accomplish, but I do understand how to break out of nested for loops (or any other nested parenthesised blocks of code). Rwinsta %%i /server:%%l & echo Disconnected sessions terminated (Optimizations welcomed) offĮcho This will look for a specific userID AND kill disconnected sessions on all servers!įor %%a in (q:scripts1commoncitrixlists*.txt) do (Įcho Looking for %username% and killing disconnected sessions on %%lįor /f "tokens=3" %%b in ('qwinsta *tcp /server:%%l ^| find /i "%userid%"') do echo %%b | rwinsta %%b /server:%%l & echo SESSION FOR %userid% KILLED ON %%lįor /f "tokens=2" %%i IN ('qwinsta /server:%%l ^| find /i "disc"') DO ( Here's what I have so far, and it works like a charm. If the session is found in farmlist2.txt, I want to FINISH searching in that list, but don't continue to farmlist3.txt. I want to cycle through the lists until I find the users session, and then stop when that list is finished (not stop when the session is cleared, they may have multiple sessions in the farm). Goal: Search for sessions on a server matching a specific user ID, and also kill any disconnected sessions found I know breaking out of a nested loop is fairly easy, however, I'm not sure how to do it when I'm working with multiple lists of servers.
