• Try to count the number of records where some columns are met

  Using SQL in Toad against an Oracle table, I'm trying to count the number of records in a table where some columns are filled. For
  example, I need to know the total number of records from a table where
  
  ln_stop_cd is not null - 65000 records
  ln_process_cd is <>- 25000 0 records
  ln_opt_cd is not null - 7500 records
  
  and the record_type = "A".
  
  I know that the total individual records as described above. However, I do not know how
  the SQL to show for record_type = 'A' the total count is 97500 records. Any help would be
  appreciated.

  Hello

  It seems that the problem is that the indictment may overlap; You can count the same rank 0, 1, 2 or 3 times, depending on whether 0, 1, 2 or 3 of these 3 independent conditions are met.

  Try something like this:

  SELECT     COUNT (in_stop_cd)
        + COUNT (CASE WHEN in_process_cd  != 0        THEN 1 END)     -- this site doesn't like the other inequality operator
        + COUNT (in_opt_cd)        AS grand_total
  FROM    table1
  WHERE     dt          >= TO_DATE ('01-JUN-2011', 'DD-MON-YYYY')
  AND     dt          <  TO_DATE ('02-JUN-2011', 'DD-MON-YYYY')
  AND     record_type       = 'A'
  ;
  

  You want to make charges without making 3 assists separated through the table. The problem is the 3 original requests had slightly different WHERE clauses.
  Put these conditions in the WHERE clause and make other conditions apply only to the individual counties, either with a column instead of *, or using a CASE statement that contains the condition that applies only to the column.

  Also, the date is not a column name good. Do not compare the DATEs to strings. If your column is really a DATE and you want to ignore the hours, the minutes and seconds, then the best way is to compare the column with 2 other DATES, as shown above. It's more coding, but it is more efficient and more reliable.

  I hope that answers your question.
  If not, post a small example data (CREATE TABLE and only relevant columns, INSERT statements) and also publish outcomes from these data.
  You don't have to display a large amount of data. You can probably give an excellent example of this problem with only 5 or 10 rows of sample data.
  Explain, using specific examples, how you get these results from these data.
  Always tell what version of Oracle you are using.

• Count the number of records between two values of keys (BTREE)

  How can I count the number of keys between two values?

  I use python driver and BTREE access method.

  = >

  Ideally, what I want is a set of whole time series data (intervals may change) to a given number of points on average. The keys are timestamps and the values are the data that it takes on average. I need to count the number of records between two timestamps so that I can divide this figure by the number of points I need and data on average. What is the best way to do it?  Or should I keep the timestamp constant intervals and use the RECNO access method?

  Thank you
  (first post btw... and why is there not a lot of people at stackoverflow that answering the questions of Berkeley DB?)

  BDB is an integrated db and there no internal counters or statistics you might grap to use for this.    You will have to do it manually.

  You can create a cursor, grap the records you want, whenever you get the next card that you bump a counter.

  If you are using RECNO, you can use a slider to obtain the number of registration (DB_GET_RECNO), and if all that you data is in

  sequentail records with no missing documents, you can find the total number of take the last rec #-original rec # + 1 to get a count.

  If you pass the SQL API, you can issue a SQL query to give you a count.  Select count (*) where...

  As you enter the data anyway, so better perhaps to count records as you go along.

• Count the number of rising edges in table 1 d

  Hello

  I wanted to measure the frequency of a pulse signal using a MCC DAQ via libraries ULx in Labview. I have two methods to do this:

  1. use the analog inputs:

  Since data acquisition has only 1 ADC, I use a commune VI acquisition for all channels and create a multi-dimensional array with different channels in rows 0-15. Then divide them by using the function "Array Index".  I think this split removes the parameter 'time' to the wave, since it is now a table 1 d. But I already know that there will be 1000 samples each 100 m everything I want to do now is to count rising edges using a function and divide it by the 0.1 to obtain the frequency in Hz, but I don't know how. Can anyone help?

  2. use the input frequency meter:

  Because I can't use the DAQ assistant, I have to use the CI frequency-> counter 1ChanNSamp DBL 1 d in the ULx library. There is no reference to take aid to and I do not know if this method is good. I have no way of knowing since I do not have a signal generator. In addition, it does not work so far.

  Help, please.

  Thank you!

  Thank you.

  I note in your first post it is seems to want to get readings of speed about 10 times per second. To get a resolution of 1 Hz frequency direct count you need to get at least 2500 counts in a range of counting at the highest frequency. This means that you need to have at least a second. Measures of the time are another option.

  Some preliminary calculations:

  Period at 2500 RPM = 2500 Hz is 400,000 Americans.

  Period at 2499 RPM = 2499 Hz is 400,160 to the United States.

  You need to be able to resolve a difference of 160 ns period. To do this directly requires 6.25 MHz sampling rate.  It is 25 times faster that your DAQ card can enjoy.

  What other options are there? Consider only your Information.vi extract. He uses techniques of Fourier transformation and interpolation to find the frequency of a signal. I set up a quick test VI to check this. Using a sampling rate of 10 kech. / s and 1000 samples per read (10 reads per second), it has easily resolution of less than 0.1 Hz at both ends of the range of speed and largely independent of the amplitude.  This is the way to go.

• Query to get the number of records

  Hi all
  
  I would get the number of records in all tables in a schema. I don't want to run select count (*) of < table name >, because there are nearly 400 paintings. So I need a generic quqeyr that will give the recordcount for all tables.
  
  Experts good help yourslef to tide me over.

  Do you need a specific account? Or an approximate count is sufficient? Do you use the RBO and CBO?

  If you use the CBO and want an approximate count, column NUM_ROWS USER_TABLES should give you what you want.

  If you need a specific account, you will have full scan all tables. You can automate this process via SQL dynamic, i.e.

  DECLARE
    l_cnt INTEGER;
  BEGIN
    FOR x IN (SELECT table_name FROM user_tables)
    LOOP
      EXECUTE IMMEDIATE 'SELECT COUNT(*) FROM ' || x.table_name INTO l_cnt;
      dbms_output.put_line( 'Table ' || x.table_name || ' has ' || l_cnt || ' rows.' );
    END LOOP;
  END;
  

  Lawrence was also a [solution based on XML Query | http://laurentschneider.com/wordpress/2007/04/how-do-i-store-the-counts-of-all-tables.html] to count all the rows in each table in a schema.

• How to count the number of data records?

  Hey guys, how to count the number of records, I had on a data object variable?

  Im having a result of sql query in a variable like this:

  oDB.resolveNode("#command").query.select.value = "SELECT * FROM Customers WHERE CliNombre LIKE ' % ' + input1 +" %' ";

  oDB.open ();

  oDB.first ();

  So I need to count the number of records retrieved by this SQL query at the moment. Help please

  Then move the cursor back to the first record after you have your account.

  There is a keyword count in SQL that will allow you to get the account of your request. You can run that first - get your account, and then run the actual query to get the Recordset. This would require a separate data connection. Some examples of code.

  var xfa.event.newText = inName;
  If (inName == "") {}
  App.Alert ("you must enter a name--try again!")
  }
  var nIndex = 0;
  While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection2")
  {
  nIndex ++;
  }

  oDB = xfa.sourceSet.nodes.item (nIndex) .racing var (1); pertaining to the specified data connection node
  App.Alert (ODB.saveXML ("Pretty"));

  var nIndex = 0;
  While (xfa.sourceSet.nodes.item (nIndex) .name! = "DataConnection3")
  {
  nIndex ++;
  }
  var oDBCount = xfa.sourceSet.nodes.item (nIndex) .racing (1); pertaining to the specified data connection node
  Configure sql call DB to get the number of records that match the criteria

  oDBCount.nodes.item (1).query.setAttribute ("text", "commandType");
  oDBCount.nodes.item (1).query.select.nodes.item (0) .value = "Select count (*) from table1 where AcctNumber = '" + inName + "'";
  oDBCount.open)
  oDBCount.close)

  Configure sql call DB to get the specified employee number

  oDB.nodes.item (1).query.setAttribute ("text", "commandType");
  oDB.nodes.item (1).query.select.nodes.item (0) .value = "Select * from table1 where AcctNumber = '" + inName + "'";
  App.Alert (ODB. Nodes.Item (1) .saveXML ("Pretty"));

  now connect to the DB and get a recording
  oDB.open)
  oDB.close ();

  Note the SQL command use the keyword count (take a look at the oDBCount section). This will return a number of return to the cllaer. When I set up the data connection, a node count (*) that appeared there. I dragged to the form and it has created a field called count that the onus at this node. When the query is executed, the number of resulting records returns to this field. You can have hidden it so that your users can not see it and also to change the binding votes to zero, so it is not included in the data file that is submitted when the form is complete.

• count the number of occurrence in the table with toplink

  Hello!
  
  There is no way to create a query with the expressionbuilder or... to count the number of occurences in my table?
  I don't want to use the query " select count (*) from table .
  
  Thank you

  Not sure about the question. You are looking to get the SQL "select count (*) table" to use the framework of expression TopLink or pull you that SQL already and want something else?

  If you are looking just to get the count of a table/class, you can use a ReportQuery:
  ReportQuery rquery = new ReportQuery (ClassToQueryOn.class);
  rquery.addCount (); equivalent to count (*);

  session.executeQuery (rquery);

  You can use a report query to return data instead of objects and use the criteria for selection as a normal read request.

• by comparing the number of records in the table child

  Child table table 3 - has that number of records for each record in Table1 (row_id in Table1 corresponds to par_row_id in table 3)
  
  I would like to run an Oracle SQL query to identify all the separate row_id on Table1, for which the number of child records in Table2 does not match the number of child records in Table3
