executes a select statement, each minute for half an hour

Hi all

I want to run a SELECT statement on a table every minute for half an hour.

Something like this:

Begin

Do all the 1 minute for 30 Min

Select col1, col2 from mytable

End

I thought about PL/SQL loop. But no matter what example with timekeeping.

I don't care?

Thank you and best regards.

Hello

As John said, you can use DBMS_SCHEDULER for this. That being said, you just can't run a query and do nothing with its result. You must do something with it.

Here is an example showing how to create a task that runs every minute for a total of 30 min

BEGIN

DBMS_SCHEDULER. Create_Job (job_name-online 'MY_JOB',

job_type-online "PLSQL_BLOCK."

job_action => ' DECLARE val1 number; val2 number; BEGIN SELECT 1, 2 INTO val1, val2 FROM DUAL; END;',

start_date => SYSDATE,

End_date => SYSDATE + 30 /(24*60),

repeat_interval => ' FREQ = MINUTELY ",

auto_drop => TRUE,

enabled-TRUE online

);

END;

It will start immediately and end 30 minutes later (it will be automatically abandoned). As you can see, the result of the query is placed in the variables. Thus, this work is useless.

When I run SQL Developer, it creates the view.
Can someone tell me why?

Thanks in advance,

Gus,

It seems that you have a completely empty line in your CREATE VIEW statement. This will cause the statement fails. If please remove this line and try again.

I want to upgrade my Safari v, but don't want to go to the Capitan - been on the website of apple for half an hour, how do I do this? Any suggestions?

I run 10.7.5 and want to update my browser safari only, do not go to Capitan. Find a Mountain Lion or Yosemite upgrade in the apple website? I watched for an hour? And Yes, I know I should have kept with upgrade... but don't want to go to Capitan, as my book air is very low.

Mountain Lion can be purchased on the Apple Online Store. If you have already not Mavericks or Yosemite from the Mac App Store, go into a physical Apple store and ask the version you want.

It is not possible to update Safari past 6.1.6 on Lion and 6.2.8 on Mountain Lion.

Create table as select statement (ETG) takes a long time.

Hi all

One of my procedure launched a table create as select statement each month.
Usually it ends in 20 minutes. for 6172063 records and 1 hour in 13699067.
But this time it never even takes to 38076 records.
When I checked everything he does is the CPU usage. No e/s.
I did a count (*) using the query, it has brought very good results.
BUT guard going on DEC.
I use Oracle 10.2.0.4.
temp_ip of the main table has 38076
table nhs_opcs_hier has 26769 records.
and table nhs_icd10_hier 49551 records.

Query is:
create the table analytic_hes.temp_ip_hier as

of ref_hd.nhs_opcs_hier one

-----------------

Any help would be greatly appreciated

Hello

It is a bit of a wild card, I think because it will require 14 scans to fill the table temp_ip to unpivot codes diagnostic and procedure, so this lilkely things are moving slower than the original. However, as it is a temporary table, I guess you could have some control over its structure, or at least be able to dismiss it and try something else. If you are able to change the structure of this table, you could make the application much simpler and probably much faster. I think that you need a list of codes of procedure for the year and a list of diagnosis for fiscal codes. I do this through the large list of UNION all THE INSTRUCTIONS, but you can have a more efficient way to do according to the base tables you are people temp_ip of. In any case, it's here (as far as I can tell this will do the same job)

JDBC PreparedStatement gives null after the execution of a valid SELECT statement

Hello

I have the following code:

    public static String GetJobLogLocation(Connection connection, int jobId) throws SQLException
    {
        String sqlstr = "SELECT LOGFILE_NAME FROM apps.fnd_concurrent_requests WHERE REQUEST_ID = ?";
        PreparedStatement prest = connection.prepareStatement(sqlstr);
        prest.setInt(1, jobId);
        ResultSet rs1 = prest.executeQuery();
        String rv = null;
        if (rs1.next())
        {
            rv = rs1.getString(1);
            System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>" + rv);
        }
        rs1.close();
        prest.close();
        return rv;
    }

As you can see, this function executes a select statement. Before I continue, let me first say that executing the exact same statement in PL/SQL Developer (external program) gives correct/expected results. In addition, run this on my Windows gives correct results environment. I seem to have this problem only on my Unix (SunOS) environment.

in any case, I get out of this function (running against my Unix environment, of course):

+ > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > > + null

The thing is, it doesn't error out, which means that the result set contains a string, but the string is returned to me with the null value, even if there is a real valid result (that is, in this case, a path).

Someone has an idea, what happens? I tried to use ojdbc6.jar AND ojdbc14.jar is, with the same results. I just don't understand...

Thank you.

ASCI says:
I'm glad that this is a not prove to be a stupid question. At least I'm feeling a little justified due to this fact.

There is no stupid question...; (o)

So what remains is: your selection is too early. Can join after insertion, update to each line to trigger the table that loggs insert/update timestamp and the contents of the LOGFIILE_NAME field?

Update a field using a select statement?
Hello
I guess it's pretty easy, but I do not understand.
I have 2 tables REQUEST and NOBODY and I want to update

UPDATE REQUEST SET SysKD = (SELECT DISTINCT PERSON. SysPERSON OF PERSON WHERE PERSON. SysVM = REQUEST. SysVK PER PERSON. SysVM > 0) WHERE REQUEST. SysLS IN (11,12).

This book error "subquery returns multiple rows. I assume that due to the fact that I have more than one record in REQUEST which fullfills REQUEST. SysLS IN (11,12).
NO ONE. SysVM > 0 is necessary because they are in PERSON and REQUEST with ANYONE. SysVM = 0 and REQUEST. SysVK = 0 (where does not REQUEST.) SysLS is 11 or 12, they all REQUEST. SysVK > 0).

I have no idea how to get a single returnvalue out of the select statement.

Thanks for help
Concerning
Carsten
Hi CarstenDD,

In the script you
```
SELECT DISTINCT PERSON.SYSPERSON) FROM PERSON
  WHERE PERSON.SYSVM = ANTRAG.SYSVK
    AND PERSON.SYSVM > 0
```
return of two or more lines, using subquery on implementation day you can use only the single row function.

You can modify your script
```
UPDATE ANTRAG SET SYSKD =
(SELECT MAX(PERSON.SYSPERSON) FROM PERSON
  WHERE PERSON.SYSVM = ANTRAG.SYSVK
    AND PERSON.SYSVM > 0)
 WHERE ANTRAG.SysLS IN (11,12);
```
then ty this please

Method 4 is the best

You could combine method 3 and 1 (without dynamic SQL)

Method 2 is the less optimal solution from the list.

Let's say that the period is 21.10.2014. -23.10.2014. and I want to get the last balance recorded for zone 1. for each day. The result should look like this:

Date         Time      Location  Box  Balance
21.10.2014.  15:00:34     1       1    1237
22.10.2014.  22:00:00     1       1    6742
23.10.2014.  23:57:12     1       1    25

So far, I managed to write a query that gives me the balance so that a SINGLE date (date more time in the table), but I need balance for EACH date in a specific period.

My incorrect code (has not managed to implement "BETWEEN" for the dates...):

SELECT TestTable.[Date], TestTable.[Time], TestTable.[Location], TestTable.[Box], TestTable.[Balance]
FROM TestTable
WHERE Time=(SELECT MAX(Time)
FROM TestTable
WHERE Location=1 AND Box=1 );

TNX!

Here's the correct query (just copy - paste):

SELECT
T1.Date,
T1.Time,
T1.Location,
T1.Box,
T1.Balance
FROM TestTable T1
INNER JOIN (
SELECT
MAX(Time) AS Max_Time
FROM TestTable
WHERE Location=1 AND Box=1 AND Date BETWEEN #10/27/2014# AND #11/1/2014#
GROUP BY Date) T2
ON T1.Time=T2.Max_Time;

The problem is in the SELECTION within the INNER JOIN. This SELECTION selects the time max for each date, because we want this and then the entire table, we choose filelds we want, but now we have only fields with the time max.

Here is a really good explanation of INNER JOIN if anyone is interested--> JOINT INTERNAL

Peace!

executes a select statement, each minute for half an hour
