These properties are used to configure tSystem running in the Standard Job framework. The Standard tSystem component belongs to the System family. The component in this framework is available in all Talend products. Use home directory. Select this check box to change the name and path of a dedicated directory.
Use Single Command. When the required command is very simple, to the degree that, for example, only one parameter is used and without space, select this option to activate its Command field. In this field, enter the simple system command. Note that the syntax is not checked. In Windows, the MS-DOS commands do not allow you to pass directly from the current folder to the folder containing the file to be launched. To launch a file, you must therefore use an initial command to change the current folder, then a second one to launch the file.
Use Array Command. Select this option to activate its Command field. In this field, enter the system command in array, one parameter per line. Standard Output and Error Output. Select the type of output for the processed data to be transferred to.
Schema and Edit Schema. A schema is a row description, it defines the number of fields to be processed and passed on to the next component. The schema is either Built-in or stored remotely in the Repository. Click Edit schema to make changes to the schema. If the current schema is of the Repository type, three options are available:. View schema : choose this option to view the schema only.
tSetGlobalVar - 6.3
Change to built-in property : choose this option to change the schema to Built-in for local changes. Update repository connection : choose this option to change the schema stored in the repository and decide whether to propagate the changes to all the Jobs upon completion. If you just want to propagate the changes to the current Job, you can select No upon completion and choose this schema metadata again in the Repository Content window.
Click Sync columns to retrieve the schema from the preceding component in the Job.Key : Name of the variable to be called in the code. Value : Value assigned to this variable. Select this check box to gather the Job processing metadata at a Job level as well as at each component level. This is an After variable and it returns a string. This variable functions only if the Die on error check box is cleared, if the component has this check box.
A Flow variable functions during the execution of a component while an After variable functions after the execution of the component. For further information about variables, see Talend Studio User Guide.
If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. For more information on this feature, see Talend Studio User Guide.
This scenario is a simple Job that prints out the value of a global variable defined in the tSetGlobalVar component. Double-click the tSetGlobalVar component to display its Basic settings view. Click the plus button to add a line in the Variables table, and fill the Key and Value fields with K1 and 20 respectively.
Then double-click the tJava component to display its Basic settings view. In the Code area, type in the following lines:. In this use case, we use the Result variable. The content of global variable K1 is displayed on the console.
Purpose tSetGlobalVar facilitates the process of defining global variables. Advanced settings tStatCatcher Statistics Select this check box to gather the Job processing metadata at a Job level as well as at each component level.
Usage This component is generally used as a one-component subjob. Log4j If you are using a subscription-based version of the Studio, the activity of this component can be logged using the log4j feature. Limitation Knowledge of Java language is required. Scenario: Printing out the content of a global variable. Setting up the Job.

The data to be loaded into a Postgresql table with the field of data type timestamp yyyy-mm-dd HH:mm:ss. The excel cannot be modified as it is being downloaded from the cloud and the data is loaded straight away into the table. I tried using tConvert type but it cannot accept null or " " values in timestamp.
I am facing a Null tMap error during runtime in talend. Even if I try to convert from string to date format in order to pass null in tmap, it is changing the date format and showing error. How can this be handled? Here is the Excel screenshot:. At first, I do not quite understand why do you want to use tConvertType component. After defining a proper schema Talend is changing your data into Java Date object and from that moment format is not important and you don't have to convert it when you want to put it into Postgres table.
At least it should not cause NullPointerException. You have to allow taking null values in by checking the Nullable check box. You should also check trim option.

In the meanwhile, will tweet out updates if anything changes. But, should not be a huge worry. UPDATE: all fixed by 11:30 AM ET today. Sorry for any issues Are prediction markets now too stable, because people trust them too much.
I explore with Andrew Gelman in a new post at Slate. I know it is not as sexy or important as the president, but senate races are just really exciting. Wisconsin and Illinois are very likely Democrats gains from Republicans in blue states. Nevada is now a tight hold for the Democrats. Indiana, Pennsylvania, New Hampshire, and Florid are all leaning Republican by a whisker. Ohio and North Carolina are leaning Republican a little more strongly. The chart tracks the probability of victory on PredictWise since we started state-by-state predictions on February 27, 2016.
I know that an efficient market should have everything priced in immediately, but the state-by-state predictions have slipped slightly above the national predictions in the last few days. She just needs to win one of those and she is president. At this point I have been constructing the predictions independently and they have stayed very consistent. If this divergence continues I will become increasingly concerned about whether the national markets are suppressed.
If there is a good lesson for American public opinion from Brexit it this. The two set of voters: leave and remain, live in a totally different reality. The remain voters got increasingly freaked out about the British economy as a possibility turned into a reality.Liquidity in index futures drops outside stock exchange trading hours because the index arbitrage players can no longer ply their trade.
If the futures price gets out of whack, they cannot hedge an index futures purchase or sale through an offsetting sale or purchase of the underlying stocks. But other market participants are still active. Index Futures Predict the Opening Direction Suppose good news comes out abroad overnight - the ECB cuts interest rates, or China reports stronger than expected growth in GDP. The local equity markets will probably rise, and investors may anticipate a stronger U. If they buy index futures, the price will go up.
And with index arbitrageurs on the sidelines until the U. As soon as New York opens, though, the index arbitrageurs will execute whatever trades are needed to bring the index futures price back in line - in this example, by buying the component stocks and selling index futures.
Investors cannot just check whether the futures price is above or below its closing value on the previous day, though. The dividend adjustments to index futures fair value change overnight (they are constant during each day), and the indicated market direction depends on the price of index futures relative to fair value regardless of the preceding close.
On a day when several big index constituents go ex-dividend, index futures may trade above the prior close but still imply a lower opening.
Trading is typically volatile at the opening, which accounts for a disproportionate amount of total trading volume.
If an institutional investor weighs in with a large buy or sell program in multiple stocks, the market impact can overwhelm whatever price movement the index futures indicate.How to use an If statement in Talend Part 33
Institutional traders do watch futures prices, of course, but the bigger the orders they have to execute, the less important the index futures direction signal becomes. Late openings can also disrupt index arbitrage activity.
Although the market opens at 9:30am, not every stock starts to trade at once. The opening price is set through an auction procedure, and if the bids and offers do not overlap, the stock remains closed until matching orders come in. The longer index arbitrageurs stay on the sidelines, the greater the chances that other market activity will negate the index futures direction signal. The Bottom Line If the futures price suggests the market will rise on the opening, investors who wish to sell that day may want to wait until after the market opens before entering their order, or set a higher price limit.
Buyers may want to hold off when index futures predict a lower opening, too. Investors can monitor futures prices and fair values on websites like CNBC or CNN Money, both of which also show pre-market indications for individual stocks (a less reliable indicator due to poor liquidity).
