Detect I/O before running sql statement
Hi all,
how do I detect I/O before running sql statement?
do you mean:
how do I know how much I/O is occurring before running a query?
or
how do I know how much I/O will be used to retrieve the data for this query?
Which OS? You can look at OEM and "top" to see your current I/O. Detecting and deciding on whether or not you want to continue to submit the query is another problem.
The question is: what problem are trying to solve? Is it really a problem or just something you imagine might occur???
Don't try to fix a non-existent problem.

Run SQL statements from a textbox
Hi
I'm trying to execute multiple insert/update or Delete statements from a textarea of a page. I'm basically trying to replicate the same functionalility as SQL Workshop for users to access and run sql statements for it.
I know in SQL workshop you can run multiple insert/update or delete statements using the following syntax:
begin
insert into table_1 (col1,col2)values('WER','QWE');
Insert into table_1 (col1,col2)values('ABC','DEF');
End;
I have created a textarea called :P1_SQL with a submit button which when pressed it runs the execute immediate :P1_SQL. It works if its a single insert command. I've tried the begin...end option which bring up the following error message:
ORA-06550: line 1, column 6: PLS-00103: Encountered the symbol "" when expecting one of the following: begin case declare exit for goto if loop mod null pragma raise return select update while with << close current delete fetch lock insert open rollback savepoint set sql execute commit forall merge pipe The symbol "begin was inserted before "" to
Any ideas how I could get this to work?
Message was edited by:
Funkymonkey2The process code that I have is as follows:
Declare
l_sql varchar2 (4000);
begin
l_sql := :P3_SQL;
execute immediate l_sql;
End;
in the textarea I had entered the following
begin
insert into TBL_TEST_SQL(name,useR_id)values('abc','erf' );
insert into TBL_TEST_SQL(name,useR_id)values('dec','erf');
end;
I was actually hoping to concatanate the 'begin...' part and the 'end;/' part on to the beginning and end of the sql statements.
Any ideas?? -

It seems when you are starting RMAN it's executing some commands (one 'ALTER SESSION...'. It's seems to be a batch which has a bad value for SORT_AREA_SIZE. Find it and modify to a proper value as message shows. If you can't find start RMAN by calling directly the executable ($ORACLE_HOME/bin/rman or %ORACLE_HOME%/bin/rman.exe). -
Where to run SQL statements in Oracle Database 11gR1 ?
Folks,
Hello. I have just installed Oracle Database 11gR1 and login to Database Control page. There are 4 tabs on the top: Database, Setup, Preference, Help and Logout.
I just create a table "table1" in "Database" tap. But I don't see anywhere to run SQL statement such as Select, Insert, Update.
Can any folk tell me where to run SQL statements in Oracle Database 11gR1 ?
Or
Can any folk provide a User Manual for Oracle DB 11gR1 ?You can run from a terminal or install an SQL client and connect from there.

Assuming you have an oracle OS user on Linux you can try typing sqlplus at you OS command prompt. Generally you will have a .bash_profile with setting like this:

TMPDIR=$TMP; export TMPDIR

Run sql statements in PL/Sql Developer without installing Oracle database?
Hi all,
I wish to ask is there any possibility to run Run sql statements in PL/Sql Developer without installing Oracle database?
Regards.Hello Jimmy,
this is the forum for the tool SQL Developer and, as the title says, *(Not for general SQL/PLSQL questions)*.
PL/Sql Developer is not an Oracle tool, but from allound allroundautomations.
And you need access to a database to run SQL statements. This does not need to be one installed by yourself.

Is it that we cannot run sql statement in main??
Hi all,
sorry to bother again. But i have some problems. I had a program that have main method and some other small methods that contains some sql statement that call the db to retrieve info. But it keep on prompting me error: "Connection refused. Check that the hostname and port is correct, and that the postmaster is running with the -i flag, which enables TCP/IP networking.".
My program reside in the server but i really don't why i cannot run it. Is it because the main program cannot run with database and sql statement.
Please reply asap. Thank You!This sound very much that your postgress isn't running (or if it isn't it wasn't started with the -i flag)
Are you sure postgres (=postmaster) is running

Hello
I have SQL statement with parameters and I want client to run it from APPS.
What should I do for this.What client are you talking about? Something like sql*plus? Or do you mean the Oracle Apps GUI front end?
The best way is to properly set this up as a concurrent request. That will allow the user to enter any parameters and run it whenever. But that's an issue for a different forum.
Whatever you do, don't give out the apps password <shudder> -
Run sql statement from batch file
How can we execute SQL Statement using Batch file???
I did a test.
create batch file test.bat
sqlplus "username@db /pass" @\script.sql
script.sql file has following statement
select sysdate from dual;
exit
it is working but I want to call sql statement in the same batch file instead of calling .sql script file. how can I do that any idea..This is very easy in unix shell scripting, but AFAIK, not available with Windows. It's a function of how the shell/command processor handles input redirection.

How do I run SQL statements with my GUI ?
Hello,
i created a simple GUI with a status text box on top and a text box on the bottom to type in sql commands. Can somebody help me modify my code so that I can at least run a create table command and give the status of "successful create table" in the top text box?
One other question I have is that I already have a login screen gui that creates the sql connection and that gui calls this gui. Do I have to pass this connection to this new class or not? and if so, how do i do it? thanks again!

Hi
When I get the sqls from v$sqlarea, does these sqls already executed, or currently runnıng?I suggest you check the Oracle Document,
While showing similar content, you might also note there are difference between V$SQLAREA and V$SQL view
V$SQL
V$SQL lists statistics on shared SQL area without the GROUP BY clause and contains one row for each child of the original SQL text entered. Statistics displayed in V$SQL are normally updated at the end of query execution. However, for long running queries, they are updated every 5 seconds. This makes it easy to see the impact of long running SQL statements while they are still in progress.
V$SQLAREA
V$SQLAREA lists statistics on shared SQL area and contains one row per SQL string. It provides statistics on SQL statements that are in memory, parsed, and ready for execution. -
Executing multiple SQL statements
I'm using the SQL worksheet in JDeveloper to run SQL statements. JDeveloper won't run more than one statement at a time. Here's an easy example:
SELECT COUNT(*)
FROM TABLE1
WHERE PRICE IS NULL;
SELECT COUNT(*)
FROM TABLE1
WHERE PRICE > 0;
I get the following error when I submit multiple statements: ORA-00911: invalid character. I'm using the studio edition version 10.1.3.2.0.
Does Anybody know how to go around this or it is just that JDeveloper doesn't handle multiple statements?Hi,
I don't have a 10.1.3 instance to check currently. I suppose there would be an option to run script (along with run option).
Try this.
Open the SQL worksheet.
Type the statements.
SELECT COUNT(*)
FROM TABLE1
WHERE PRICE IS NULL;
SELECT COUNT(*)
FROM TABLE1
WHERE PRICE > 0;Select all (Ctrl+A), right click and see if you have a Run Script option in the context menu. If yes, select and it would work fine.

Calling SQL statements from Shell scripts
Hi,
I want to call external package procedures, declare some variables & do some oracle validations in the shell script.
How SQL environment is set in shell script & is this one time process or I have to write few statements before every SQL statement.
Please explain with an example.
Thanks..is this one time process Yes. Example :

Error Running SQL Insert Statement with & in it
Eclipse: 3.5 Galileo on Window Vista
OEPE: 11gR1 11.1.14
I get "invalid character" error when running this query in Eclipse:
INSERT INTO RECIPE (recipeId, name1, name2, recipeCategoryId) VALUES (2, 'Chunky Chicken Egg Rolls', 'No take–out joint can compare!', 1);
I've tried multiple ways trying to escape the & character, but nothing worked. What is the right way of executing SLQ via OEPE plugin that have special characters in them.
FYI, the following worked fine in Oracle 10g iSQL*Plus:
SET DEFINE ~;
INSERT INTO RECIPE (recipeId, name1, name2, recipeCategoryId) VALUES (2, 'Chunky Chicken Egg Rolls', 'No take–out joint can compare!', 1);
Thanks,
Dmitri.Very interesting case. I tried your insert stmt and got the same error. I finally got it to work by removing the ";" in the end. It looks like the jdbc driver choked up while there is ";" in the middle of the pl/sql statement and ";" in the end. If you remove ";" in the "No take–out joint can compare!" string and leave the ";" in the end, it also works!
I don't quite understand why Oracle JDBC dirver behaves like that. I'll investigate it more and we may need to do some preprocessing on the pl/sql statement before sending it to the driver. At the mean time, just remove the ";" in the end if your string literal contains ";".
Please let me know whether this workaround works for you. Thanks!
