Does ProC/C Generate Calls to the Oracle Call Interface? Why Not Code Using SQLLIB Calls and Not Use ProC/C? Can I Call A PL/SQL Stored Procedure From a ProC/C Program? Can I Write C Code, and Precompile It Using ProC/C? Can I Use Bind Variables Anywhere in a SQL Statement? I Am Confused By Character Handling in ProC/C. ProC is client code. It owns it own physical executable process. It creates a client-server session with Oracle. PL/SQL is server code. It is executed inside an Oracle server process. So there is no need for PL/SQL to "connect" to the database server - it runs inside the database server. 16/02/2011 · PL/SQL, running inside an Oracle server process, has none of these devices. It is not attached to a keyboard. Cannot write to a graphic or console window. You can however create a buffer in that server process, write to it via PL/SQL, and then the client that owns that server session can read this buffer and display it. This is what DBMS_OUPUT. Subject: ProC/ProCobol vs PL/SQL Performance Dear all, Has anyone done any testing in this area? Any findings? We've done a simple test here and found that the precompilers were much slower than PL/SQL. The program just had a loop that fetches a row from a tiny table 20K times. The problem seems to be with the number of roundtrips the precompiler.
24/07/2003 · Pro C/C Passing CLOB to PL/SQL Proc 399638 Jul 22, 2003 11:37 PM I have been attempting to pass a temporary CLOB to a PL/SQL Procedure that should populate it. One of the common scenarios of using such a loop is when data is available in an array that would be used somewhere else in the program but in some sections, you. C and C also have the ability to do some operating system tasks that are difficult or impossible to do directly in PL\SQL. PL\SQL has the advantage of being relatively easy to use for someone who knows SQL, but doesn't know C or C and/or doesn't have a C compiler.
Yes it might be more efficient to call SQL directly from ProC, as opposed to calling SQL from PL/SQL from ProC, if that is the only choice. Perhaps Vinu can confirm how the application accesses the database to launch its 100-commits-per-second attack btw Vinu, you need to find a way of not committing 100 times per second.

Would it be more efficient to pass the array into a pl/sql block defined in the host program and let it call the server-side package for each element of the array, or should I code a further procedure in the server-side package to receive the array and have it.

You do that by running two SQLPlus scripts, exampbld and examplod, which are supplied with PL/SQL. You can find these scripts in the PL/SQL demo directory. I am using your ProC program for dowloading oracle table data to ascii format and found it very fast. Will you pl tell me why it is faster than SQL or PL/SQL ? Secondly, If I want to write a query which are selecting millions of records and having option to write in SQL or PL/SQL or ProC, then which option I should write a query? Pl tell me why. PL/SQL is easier to code and maintain, but see 2 below 2. Processing speed -- which option between proc and pl/sql if there are minimal/heavy processing involved. PL/SQL is fundamentally about data-processing not file processing. So whilst PLSQL and Proc on the db server will both run pretty much the same speed at retrieving your data. I don't know C but in JDBC you cannot send more than one statement using the execute function. I assume this is a restriction imposed by the Oracle protocol and therefor I. intermixing regular C with ProC statements as you can see and then you run it through the ProC compiler. What comes out of that is a C program which has the ProC statements replaced with the equivalent function calls which will do the same thing.

ProC uses either C or C as its host language. During compilation, the embedded SQL statements are interpreted by a precompiler and replaced by C or C function calls to their respective SQL library. The output from the ProC precompiler is standard C or C code that is then compiled by any one of several C or C compilers into an executable. The main idea into PL/SQL terms. Now we are going to provide a brief description of how working mine idea about PL/SQL control over Oracle transactions [I]. In this first point we will go to execute only one alone store procedure as Pl/SQL with help of 'ExecuteNonQuery' C code. Of course you may use and other C methods to execute a store. Unlike SQL, PL/SQL allows you to group SQL statements logically and send them to Oracle in a block rather than one by one. This reduces network traffic and processing overhead. For more information about PL/SQL, including how to embed it in an application program, see Chapter 7, "Embedded PL/SQL". What Does the ProC/C Precompiler Offer?
