Can I get the total number of records that meet the conditions of a query using the Table API?
Hello
A < row > TableIterator is returned when I ask operations using the index of tables. If I want to get the total number of records, I count one by one using the returned TableIterator < row >.
Can I get the total number of records directly meets the conditions of the query?
I can get the total number of records directly the request of the meeting of the conditions of CLI using the command Global table - name tableName - count - index index-name-field fieldName - start startValue-end endValue.
Can I get the same results using the Table API?
I used MongoDB and NoSQL Oracle for about a year. According to the experience of the use of these dbs, I think mongoDB querying interface is powerful. In the contras, the query interface is relatively simple, which results is a lot of work that is usually a long time in the client side.
Hello
Counting records in a database is a tricky thing. Any system that gives you an accurate count of the records will have a hotspot of concurrency on updates, namely the place where the counting is maintained. Such a count is a problem of performance in addition to competitive access problem. The problem is even more difficult in a system widely distributed such a NoSQL database.
The CLI has overall command that counts, but does so by brutal force - iterate keys that correspond to the parameters of the operation. This is how you must do this within the API. There is not a lot of code, but you have to write. You certainly want to use TableIterator
If you use TableAPI.multiGet () and a key with a touch of brightness full then, in fact, count the results as they are returned in a single piece (a list). Kind regards George

great keyoard layout, the T410 but where can I get the table
I installed a 64-bit win7 ultimate on my T410 instead of 32 bits that came with it.
I managed to restore all the drivers, but I can't find appropriate keyboard table.
Can someone give me a clue.
I have 3 characters on most of the keys, @ left superior (under ESC).
Kind regards
Jos Meijer
I found the solution. However.
As Ubuntu does not consider as brain + dead computer (like Bill Gates) users, I could easily navigate through various keyboards available.
Guess what? I am lucky to have a Dutch keyboard (never seen one before in Holland!) -
Unable to get the total number of records processed by the processor of trade rules
Details of the environment
======================
Disqualification Version: 12.1.3.0.0
I use a business rules processor to implement multiple business rules on one record and I am looking for a summary of the number of records increased and does not have a specific rule.
To illustrate:
Suppose there are 2 rules, invalid number in Column1 and valid number on Column2.
10 records to process and 3 folders don't rule 1 (valid on column1) and 9 entered failure of rule 2 (valid number on Column2).In the browser of result of the processor Business, the number of past records and failed is displayed but is not part of the output of the processor itself. In the example above, there will be 1 pass and 9 fail records and given the values of said the total number of records can be derived which is 10.
This is why the expected output will be:
Success of failure
Rule 1:7 (10-3) 3
Rule 2: 1 (10-1) 9
Note: The number of records that failed can be derived from the table of the rule ID but I don't know how to get the total number of records in order to calculate the number of records that a given rule.I tried to publish the County of acceptance and rejection in the browser of result of the processor Business in an intermediate table and ask the same intermediate table to get the pass and fail values but Disqualification does not allow to write and read the same intermediary object in a single process. What is the best way to get the number of records total handled by the processor business rules? This kind of attributes (that do not exist only in the browser of result) can be included in the output of the processor in the next version of the Disqualification?
In addition, the intermediate table contains only 1 sheet with pass and failure values while the exceptions which have individual failure on each rule contains 12 Archives. What would be the best approach to merge a single record into multiple records according to the example below?
Staging table
Success of failure
1 9Exception table
Single ID ID rule
Rule 1 Record1
Rule 1 Record2
Rule 1 record Record3
Rule 2 Record1Exception table with: staging Table data merge
Rule ID ID Unique Pass Fail Total
Rule 1 1 9 10 Record1
Rule 1 1 9 10 Record2
Recording rule 1 Record3 1 9 10
Record1 rule 2 1 9 10
Please notify.Hi Jason,
The best way to explain how to do this is with an example project (DXI). I'll send you one in offline mode.

How can I get the total amount of keyframes in the timeline
I'm building a very simple, single timeline based resource. I want to be able to count the number of pages and display the page number, I'm sure. The resource uses sym.stop (); on the timeline, and the sym.play(1000) () attached to a button. The idea is that I have 2 global variables. 1 that updates the progress of keyframes 'pageNum' and one that calculates the total number of pages (keyframes) on the timeline 'totalPages '.
"pageNum" is very good, simply a case of incrementing the timeline progress, as I have, but I'm stuck on getting the total number of keyframes. Of course, in the code pane I can look through and count the number of functions "Trigger XXXX @ ms", but can I get the code to do it for me?
See you soon
SeanHey,.
It is ok. I thought about it, although it is very ugly.
totalPages = 0;
convert the file edgeActions.js to a string
$.get ('myAnimateProject_edgeActions.js', {function (data)})
var data = dataAsStr;
Look in the 'Editing by default' file as this defines where the triggers are
var match = dataAsStr.match (/ default Timeline/g);
get the length of the returned array
totalPages = match.length;
});
If there is an easier way, I'd love to hear, or if people think this way could throw up problems. In the meantime, this will make numbering pages much easier and works for this project
Thank you for your ideas resdeign.

Hello
When pairing manually, you must press the name of 5 digits on the screen of your iPhone (when he shows the same device name that is shown on your watch, after typed it on your watch's 'i'):
Your watch then displays a six-digit code, you will then enter on your iPhone:

For reasons of confidentiality, Apple doesn't want you to access specific information of any peripheral such as MAC IMEI, UDID, address, serial number, etc and has been remove support for this kind of information the SDK for awhile now. Your application will be rejected if you try to use private methods, that's probably what they were talking about.

I can't get the bookmarks to record properly... The yellow star lights (even when I return to the site), but there is no indication when I try to view all bookmarks. Nothing shows no more on the bookmarks toolbar. Backup files seem to be empty. I tried to restart with all add-ons disabled in safe mode and it still wouldn't save a bookmark correctly.
One possible cause is a problem with the places.sqlite file that stores the bookmarks and history.

There is no option to save the video in mp4 format only. You can check on the MProot folder on your memory card for mp4 files. The. MTS files are normally saved in another folder called flow.
