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"?
I have compiled some procedures, at the time of compilation i saw some warnings & errors but i did not notice, Now can we see that errors or warnings in db console or any other way.
View 7 Replies View RelatedI have a requirement to create a packaged proc which lists down a set of database objects and its statuses whenever the status of objects is changed as valid/invalid in user_objects. Also, those valid objects need to be compiled while running the packaged proc.

In the above statements, product is a table. Now, I could able to access this table from user 'user2'. But however if I write a procedure in user2 schema accessing the table product, then the procedure is not getting compiled.

i have a little curiosity in result of a select statement.
One database has following characterset settings:
NLS_CHARACTERSET WE8ISO8859P15
NLS_NCHAR_CHARACTERSET AL16UTF16
and the following select statement results in multiple lines:
SQL> select INSTANCE_NAME,STATUS from v$instance;
INSTANCE_NAME
------------------------------------------------
STATUS
------------------------------------
BUP
OPEN
Another database has following characterset settings:
NLS_CHARACTERSET UTF8
NLS_NCHAR_CHARACTERSET AL16UTF16
and the same select shows only a 2 line result:
SQL> select INSTANCE_NAME,STATUS from v$instance;
INSTANCE_NAME STATUS
---------------- ------------------------------------
HPSMP OPEN
Both databases are version 10.2.0.4 and both are running on HPUX 11.31.Why do we get this differents in showing the result?
Our problem is that the package-start scripts from HP, to start a database, check the result of the select statement above and if we have the multiline result the check gives an error and stops the package again.
I come from a world of MSSQL and have been thrown into doing some Oracle work. Great! Ok, moving on.. I work in an environment where I do not have direct access to the database tables that I need data from. As a workaround, I have been asked to create a stored procedure that will be loaded into our CRM system's production db once it goes through the internal "approval" process.Basically, I need to return a result set back to the client by calling a stored procedure.
Version 1 of this that was already in place was done with the following code.
procedure events_by_day (p_start_date IN OPERATION_LOG.DT%type,
p_end_date IN OPERATION_LOG.DT%type,
p_results OUT SYS_REFCURSOR) IS
BEGIN
OPEN p_results FOR
[code]....
Then the code is executed from the client side like so:
events_by_day(p_start_date => to_date('2012-3-27 00:00:00', 'YYYY-MM-DD HH24:MI:SS'),
p_end_date => to_date('2012-3-29 23:59:59', 'YYYY-MM-DD HH24:MI:SS'),
p_results => r_cursor);
LOOP
FETCH r_cursor
INTO event_date, event_acct_no, event_type, event_count;
[code]....
As you can see, a SYS_REFCURSOR was used in this case to pass the data back.
I have two queries. One selects 5 values (all number datatypes), the second query selects 2 values (both number datatypes).If a value from query 2 exists in the resultset of query 1 - go make table updates using the second value in the select statment of query 2. If there is not a match, update a table with values from query 1.
Currently, I have two cursor for loops, which are nested. This works but of course is horribly slow. What is a better way to process this data?The number of rows varies between the two resultsets.

How to make the automatic deletion of all the archivelogs when it is applied successfully on the standby database? We have 1 primary database and 1 standby database using oracle physical dataguard.
In the primary database, we have daily backup job so that the applied archivelogs are deleted automatically, no problem
But in the standby database ( physical standby) I have to go there and delete manually because I don't issue backup on this database. Is there any solution for this problem.

I am using Oracle 9i and Unix on my system and trying to execute a UNIX shell command through external procedure in C.I created a shared lib (libextproc.so) for the following function.
int sysrun(char *command)
{
return system(command);
}
This function runs fine when caled through a driver function in C, meaning that the shared lib is fine.In PL/SQL, I have used the following method to invoke a UNIX command:-
create or replace library shell_lib as '/home/ECETRAonsite/oracle/OraHome1/lib/libextproc.so';
/
create or replace function sysrun (syscomm in varchar2)
return binary_integer
