" c) Procedural part can be parsed either by an application tool or oracle kernel. The thing to watch for is the version of the PL/SQL engine embedded in the application tool. The ideal situation is when these two versions are the same. If they are not, life can get interesting."
To put it MILDLY!!! Dick Goulet ____________________Reply Separator____________________ Author: "Gogala; Mladen" <[EMAIL PROTECTED]> Date: 3/24/2003 7:08 AM Let me throw some shade onto the issue: a) PL/SQL engine does not execute SQL statements - ever. It passes them over to the SQL Executor engine. b) PL/SQL is just a procedural enclosure of the SQL language. There is another one: it's called Java. c) Procedural part can be parsed either by an application tool or oracle kernel. The thing to watch for is the version of the PL/SQL engine embedded in the application tool. The ideal situation is when these two versions are the same. If they are not, life can get interesting. -----Original Message----- Sent: Monday, March 24, 2003 4:29 AM To: Multiple recipients of list ORACLE-L Hi List, I was going thru Oracle "PL/SQL User's Guide and Reference". http://otn.oracle.com/docs/products/oracle9i/doc_library/release2/appdev.920 /a96624/01_oview.htm#962 Paragraphs below (near the "Figure 1-4 PL/SQL Engine" in the doc) confused me little. para1 --- "These two environments are independent. PL/SQL is bundled with the Oracle server but might be unavailable in some tools. In either environment, the PL/SQL engine accepts as input any valid PL/SQL block or subprogram. Figure 1-4 shows the PL/SQL engine processing an anonymous block. The engine executes procedural statements but sends SQL statements to the SQL Statement Executor in the Oracle server." para2-- "In the Oracle Database Server: Application development tools that lack a local PL/SQL engine must rely on Oracle to process PL/SQL blocks and subprograms. When it contains the PL/SQL engine, an Oracle server can process PL/SQL blocks and subprograms as well as single SQL statements. The Oracle server passes the blocks and subprograms to its local PL/SQL engine." Now my doubt is: 1.In para1 - Does pl/sql engine only processes the procedural statements and always passes SQL statements to SQL Statement Executor ? 2.In para2 sentence "When it contains ..." says Oracle pl/sql engine can process SQL statements. Statements in both paragraphs seems ambiguous. Pls shade some light. Thanks Sam __________________________________________________ Do you Yahoo!? Yahoo!
