SQL & PL/SQL :: Reading Oracle Statements From A Procedure / Function?
Sep 15, 2010
I want to read the oracle procedure/function and find out the no of valid sql statment lines in a procedure:--
Consider the procedure is like :--
PROCEDURE TESTVAR IS
l_local number;
i integer;
j integer;
BEGIN
SELECT real_id_number
[code]....
Now i want to read this procedure in such a way that it should return me below output :-
Seq_No Sql_Statements
1 SELECT real_id_number
2 into l_local
3 FROM master_var v
4 where v.variable_type = i
5 AND V.ID_NUMBER = j ;
how to achieve this output.

connect the following concepts/information I've been collecting. This is not my field but I'm interested in filling some of mine conceptual/technical gaps.
From a JDBC perspective, one of the benefits of Prepared (and so Callable) statements have over the regular ones is that the statement is "compiled"(*) once and then reused (performance gain).
(*) for SQL statements: building of parse tree and exec.plan
In which way can this notion be extrapolated to invocation of Oracle Stored Procedures through CallableStatements? (After clearing my doubts, I may end concluding that the only relevant feature of CallableStatements is their capacity to deal with stored procedure invocations)
According to procedure's precompiled execution plan SQL compilation implies execution plans generation PL/SQL compilation implies P-code generation and, SQL statements (from PLSQL code) are treated no differently by Oracle than SQL from Java or C/C++. These SQLs will be parsed and execution plans for those SQLs created.
...
When the PL code executes the SQL statement, only then does the SQL engine receive the SQL, parse it, and create an execution plan for it.
Therefore, even when the stored procedure can be parsed and cached in SGA (through the OracleConnection.preparedCall("proc") invocation), the SQL statements won't be effectively compiled until they are executed, right? And going deeper, will those SQL statements be cached to be reused in future invocations of the containing stored procedure? Is this a characteristic of the regular stored procedure execution in Oracle? or is it due to the CallableStatement "origin"?

One of the procedures that am working on is failing with ORA-0000: normal, successful completion error.
The procedure has got several update and delete statements and have logging enabled after each step. The problem with that again is, each time the log table gets updated thereby losing the history of until what point the procedure ran successfully.I have this issue only in production environment and unable to simulate it in dev environment which limits my options of troubleshooting the procedure code. I was using SQLERRM in the code.
Is there a way I can identify the bad records/ record causing this issue? Am very new to PL/SQL and do not know how to proceed with this.How do you debug this sort of issues??(where one procedure internally invokes another one which again invokes other one etc)

here's my question.
(I'm using PL/SQL Developer with Oracle 10g)
I have an table 'tbcontrol' where for each row I can have one or more sql statements (DML or DDL) in an column.
Example:
task | sql_scripts
1 | create table t1 (c1 number); insert into t1 (c1) values 100;
2 | create table t2 (c2 number); alter table t1 modify c1 not null default 0;
3 | alter table t2 modify c2 not null default 0; alter table t1 add c10 varchar2(10); create table t3 (c3 number not null default 0;
I need to create a procedure where I can pass an task number to execute the sql statements which are in the column 'sql_scripts'. Something like this:
create or replace sp_run_scripts (v_task number)
is
v_scripts varchar2(2000);
begin
select sql_scripts into v_scripts from tbcontrol where task = v_task
execute immediate v_scripts;
end;
But, here I'll have some problems:
- The script will have semicolons (EXECUTE IMMEDIATE doesn't support);
- If I put a begin/end like a PL/SQL script, I can only run DML statements because DDL statements have implicit commit.
- I can't use a cursor for execute each statement at a time because the scripts have multiples-rows. Even if I search for semicolons to 'separate' the scripts in the cursor (using SUBSTR and INSTR functions), I'll have problems with the semicolons between '' (quotations marks).
Now, I admit I'm lost.
Is there another way to make this process work?

I am developing android application connected to Oracle database using PHP, and I use PL/SQL statements with semantic technologies provided in Oracle(specifically, SEM_MATCH, SEM_MODELS, SEM_RULEBASES or something like this).
However, it doesn't work properly...the connection between android and Oracle works well, though. Also, the query statement is implemented well in the sql developer.The whole php code is shown below :
*<?php*
function db_connect()
*{*
*$db = "(DESCRIPTION=(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 203.249.105.20)(PORT = 1521)))(CONNECT_DATA=(SID=orcl)))";*
[code]...

I am currently studying a Foundation degree in computer software development, and one of my assignment in PL/SQL I am stuck on one of the tasks.
I have to create a procedure where one of the parameters needs to have a default value of one, if no value is entered when the procedure is called. I have trued to use the NVL function which worked when using a anonymous block, but now I have to convert that to a procedure. My problem is I'm getting an error.
The code for the procedure is
CREATE OR REPLACE PROCEDURE add_new_classes
(p_number_of_classes NUMBER := NVL(NULL,1), -- This will enter a default value of 1 if the user does not specify a number
p_course_id classes.course_id%TYPE,
p_period classes.period%TYPE,
p_frequency classes.frequency%TYPE,
[code]....
I then use this to test it
BEGIN
add_new_classes(1002,'first','daily',3002);
END;
and the error I get is
Quote:ORA-06550: line 2, column 4:
PLS-00306: wrong number or types of arguments in call to 'ADD_NEW_CLASSES'
ORA-06550: line 2, column 4:
PL/SQL: Statement ignored
1. BEGIN
2. add_new_classes(1002,'first','daily',3002);
3. END;

I know difference between procedure and function.if we want a return value from procedure, we can have OUT parameter. Similarly with function, in addition to returning a value from function, it can also send an OUT parameter value as a return value. That means, in one or the other way we are able to get a return value from both program units. Normally, I would fill a OUT variable with error message when an exception occurs. I use this varaible,after procedure call, to detect if an exception occurred or not. Similar task can be performed by a function, it returns a true/false and a value thru OUT variables.
both program units return values in the form of OUT parameters. Where exactly should we use a function, where exactly should we use a procedure?

difference between Procedure and Function.We Know that Procedure is Basically Used to perform Actions and Functions are Basically Used for Calculations but what would be the exact difference since Actions/Calculations can be done in both Procedure and Functions.Which factors decide whether we need to write a Procedure and in which cases we need Function.

I have to call oracle stored procedure or a function to update user id of one or several rows depending on what user selects.
The oracle person will be writing the stored procedure or function. I am a java developer but was never involved in writing oracle functions. So..
I want to know what is the difference betn stored procedure and function?
From java point of view are there any guidelines when to prefer one over the other(betn stored procedure and function).

I would like to know if it is possible to get the arguments of a function (or procedure), in the same way as - for example - the "arguments" object in JavaScript.
I have seen the table ALL_ARGUMENTS, for example, that is providing a lot of interesting details, but I still miss the most important for me: the values of the arguments, not only the name, or type, etc...
Something that could be called as soon as the function (or procedure) is run, at the beginning of its process, and that would give a kind of array of arguments values.

i'm trying to make a sp/function for inserting a record and return the new index.The previous code used regular inserts and needed an additional round-trip to get the id before inserting,, since this is part of a import routine performance is an issue.

P_Id Out Number,
P_ImportedOn IN Date,
P_Aisimporttypeid In Number,
P_Description In Varchar2,
