Game max fixed the number of rows in a table

Hi all

I created a table that should contain only one line and avoid the possibility to add other lines to it, I used the following:

CREATE TABLE <table_name> (
    <field_1> <field_type> unique,
    ...
    <field_2> <field_type>
    CONSTRAINT <field_1_ck> CHECK (<field_1> = <value>) 
);

It works, but it seems a bit heavy for me... Is there a better way to define a fixed/maximum number of rows in a table?

See you soon,.

Count the number of rows in a table (s)

Hi all
I have a TKT_PRIORITY_LK table that I want to count the number of rows returned by a priority level... say Low, Medium, High, critical. I want to be able to count how many of each created are they, instead returning ID instead, if making any sense... Can you please help with this.
Example; Select count (*) in TKT_PRIORITY_LK
PRIORITY group
Kind regards

Try this

Select a.PRIORITY, count (*) from TKT_PRIORITY_LK a, TKT_TICKET_MAIN b

where a.id = b.PRIORITY_ID

get the number of rows affected by their table top

Hello, I need to count the number of rows updated in table form. In the process of ApplyMRU, I can use the string substitution #MRU_COUNT # to show the lines updated in a success message, but I need to get this value and store it on a table. Any help would be much appreciated. Thank you.

For that you would benefit from the APEX$ ROW_STATUS integrated substitution string.

1. create a page element display only (in my case P15_UPDATED_ROWS) Save Session State set to Yes and the Type of Condition is set to never.

2. Add a calculation after the shows with a Type of static assignment and calculation value 0 to reset the counter whenever the page is sent.

3. Add an On submit - after calculations and Validations process of PL/SQL page linked to your tabular presentation with a Status of Type PL/SQL Expression and Expression 1 :apex$row_status = 'U' and the code of the following process :
```
:p15_updated_rows := :p15_updated_rows + 1;
```
If you don't actually means "day" in the strict sense, and then change the status of process to include possible APEX$ ROW_STATUS 'C', 'U', and "D" values as needed. If you want to count all created, updated and deleted lines, do not add the condition to the process, but make sure the extended run is set to createand changed lines.

How to determine the number of rows in the database and save the result to a local variable?

Hello

I'm a newbie in the use of TestStand, databases and SQL, and now I've met difficulties. I use TestStand 2014 (32 bit).

I have a need to know the number of rows in a database and save that number in a local variable. I tried to practice using the database of the Types of step provided with TS. I tried to use the following in a SQL statement:

Locals.NumberOfRows = ("SELECT COUNT (*) FROM TEST_TABLE")

It returns an error: specified value is not the expected type. My goal is possible in this way, or I'm doing this completely wrong?

-RautSa

Thank you for your response, Norbert. I have a database of who wins new values at random, and sometimes I need the exact number of rows in this table.

I managed to achieve my goal by using the SQL statement: "SELECT COUNT (*) as Rowcount OF TEST_TABLE", followed by a data GET operation, which records that number of lines in a local variable.

See the number of rows affected the performance of sqlplus to a sql file

Hello

It's just we have a sql file that contains a bunch of select/update/insert statements.

I have a unix script that calls sqlplus on this sql file. However, at the exit I don't get the number of rows affected.

Without adding any code in the input sql file, how can I change the code of sqlplus shell script to print the number of rows affected for each statement in the sql file?

${ORACLE_HOME}/bin/sqlplus -L >> ${LOG_FILE} 2>&1  << EOF

  whenever sqlerror exit sql.sqlcode;
  set echo on;
  set feedback off;
  set serveroutput on;
  @${SQL_FILE};
  exit;

The SQL_FILE of entry content is:

select 12 "col1" from dual;
select 'abcd' "col2" from dual;
select;
select 13 'col3' from dual;

How can I get the number of rows in the table using Sunopsis API target in ODI 10 g?
Hi guys,.

In fact, I want to send an alert message as soon as the interface is run from a package. I've included alert OdiSendMail that sends an email once the interface is running.

Could someone please tell how to get the number of rows inserted into the table the Sunopsis API target.

I tried to use < % = odiRef.getNbRows () % >, but this has not worked for me. Since I am a beginner, could you please help out me

This is my mail to send ODI format

"The population of data managed to < % = odiRef.getSysDate () % >

Total of lines in the target table is: < - need an API code-> "

Kind regards

Hello

Create the project with details below variable

Nom_de_variable: Total_Row_Count

Type of variable: Variable discount

Definition tab:
Data type: digital
Action: No persistent

Refresh the tab:
Schema: provide the schema of your repository to work and be

SELECT log.nb_row
THE journal of snp_step_log, snp_scen_step step
WHERE log.nno = step.nno
AND step.scen_no = (SELECT scen_no FROM snp_scen_step WHERE step_name='<%=odiRef.getPrevStepLog ('STEP_NAME") % > ')
AND log.sess_no = '< % = odiRef.getSession ("SESS_NO") % >' code at low
AND step.step_name = ' < % = odiRef.getPrevStepLog ("STEP_NAME") % > '

Note: add this variable after the stage of interface in your package (after the interface anywhere you can place), you can add this variable before ODISendEmailNotification in your package

call this varciable * #Total_Row_Count * in the Notification of ODISendEmail

for example :

Data has been fulfilled successfully in < % = odiRef.getSysDate () % >
Total no of lines filled are: * #Total_Row_Count *

it will work

cordially,

Displays the number of rows in the table displaying a named criteria query data
I created a test named for my View, called 'Criteria1' and Criteria1 to create a group of ADF with Table query. I want to display the number of rows in result when a search is performed. How can I do?

Thanks in advance,
Tom
As mentioned, you can add outputText and you must give OutputText partialTriggers as query component your Id. Thus, when you give a search on the query component, it will refresh the outputText with the number of lines.

ID = "ot1" partialTriggers = "id of the component of motion here" / > ""

Get the number of rows in the oracle table

Hi all
I want to get the total number of rows in the sql to the appmodule table.
After you apply the criteria to view some on the view object. If he try with getallrowsinrange the number of rows found within the viewobject was but I want a total number of rows in the sql table.

How can I get that

I use jdev 11.1.1.5

Thanks in advance

I threw something together, quick and dirty, don't hesitate to optimize.

Assuming you want the County table, I put the code in a subclass of EntityDefImpl since it is representing a table in the middle tier.

public class EmpDefImpl
      extends EntityDefImpl {
  /**
   * This is the default constructor (do not remove).
   */
  public EmpDefImpl( ) {}

  //~ Methods ****************************************************************************

  public long getTableRowCount( DBTransaction transaction ) {
    String query = getQuery( );
    String countQuery = String.format( "SELECT COUNT(*) FROM (%s)", query );
    long count = 0;

    ViewObject vo = transaction.createViewObjectFromQueryStmt( countQuery );

    try {
      vo.executeQuery( );

      Row row = vo.first( );
      Number number = (Number)row.getAttribute( 0 );
      count = number.longValue( );
    } finally {
      vo.remove( );
    }

    return count;
  }
}

Depending on your card type, you may not get an oracle.jbo.domain.Number, but something else, so the cast may need correction.

Usage example:

public class EmpEditViewImpl extends ViewObjectImpl {
  public EmpEditViewImpl() {
  }

  protected void executeQueryForCollection( Object object, Object[] object2, int i ) {
    super.executeQueryForCollection( object, object2, i );

    EmpDefImpl def = ( EmpDefImpl )getEntityDef( 0 );
    long tableRowCount = def.getTableRowCount( getDBTransaction() ) );

    // Do something with it
  }
}

As you can see, the code is fairly generic. Also, you might be able to put this in a base extension ADF class.

How can I add a last column that counts the number of rows returned by this view?

EDIT - here is a dump of my paintings, and here are my views.

Edit2 - this is possible by using the DECODE function, by chance?

The function...

CREATE OR REPLACE FUNCTION view_row_count (view_name VARCHAR2)
RETURN NUMBER
AS
retval NUMBER;
BEGIN
EXECUTE IMMEDIATE
'select count(*) from '||view_name INTO retval;
RETURN retval;
END view_row_count;
/

And now the query...

select
object_name,
created,
last_ddl_time,
view_row_count(object_name) as view_row_count
from user_objects
where object_type = 'VIEW'
