setting a unique date format
Talend Data Preparation supports many different date formats, which you can harmonize to improve your data.
You can see in the SubDate column that even if your data respects the semantic type set as date, they do not follow only one date format. As a consequence, European and American standards, - and / are coexisting.
You are going to harmonize the SubDate column and set only one date format for all your data. To do so:
Procedure
-
Click the header of the SubDate column to select its
content.
-
In the statistics box on the bottom right, click
Pattern.
This tab gives you a better view of the different date formats currently used. Some dates follow the European standard, while other follow the American format. In any case, you can see that the dd-MMM-yyyy format is the most commonly used.
-
To standardize the date format, click Change date
format... in the functions list.
A menu opens, where you can specify the current date formats, and the desired one.
-
In the Your format field, type
dd-MMM-yyyy.
The dd-MMM-yyyy format is the most suited since it is the one that already had the most occurrences.
Results
The SubDate column now follows only one date format, which make it easier to read. You can also notice that the recipe highlights your last action and it is even possible to modify the date format again, directly from the recipe.
