Converting a string to a date in Azure Data Factory can be a bit tricky, but don't worry, I've got you covered.
You can use the Date function in Azure Data Factory to convert a string to a date. This function takes in a string parameter and returns a date value.
The Date function is case-insensitive, so you can use it with strings in either uppercase or lowercase. For example, '2022-01-01' or '2022-01-01 00:00:00'.
Getting Current Date and Time
You can get the current date and time in Azure Data Factory (ADF) using the utcnow() function.
The utcnow() function returns the current date and time in the format "Wednesday, September 01, 2021". You can also specify the format, such as 'D' to get the date with Day, which will return "Wednesday".
To get the current year, you can use the following code expressions:
- For the year as a five-digit number:
- For the year as a four-digit number:
- For the year from 00 to 99:
You can also convert the current date time to a specific format using the utcnow() function with the desired format. For example, to get the current date time in 'dd-MM-yyyy hh:mm:ss' format, you can use the utcnow() function with the specified format.
Here are some examples of how to get the current date and time in different formats:
- To get the current date in 'dd-MMM-yyyy' format:
- To get the current date in 'dd-mm-yyyy' format:
- To get the current date in 'mm-dd-yyyy' format:
- To get the current date in 'mm-dd-yy' format:
- To get the current date in 'yy-mm-dd' format:
- To get the current date time in 'dd-MM-yy hh:mm' format:
Note: You can replace the characters in the examples above with the corresponding codes from the following table to generate the date time or date in your desired format.
Date and Time Conversion
Date and Time Conversion is a crucial aspect of Azure Data Factory (ADF) that can be achieved through various methods. You can use the utcnow() function to get the current date and time.
To get the current date in a specific format, you can use the following code expressions: "01-Sep-2021" for 'dd-MMM-yyyy' format, "01-09-2021" for 'dd-mm-yyyy' format, and "09-01-2021" for 'mm-dd-yyyy' format.
You can also use the convertTimeZone method to convert UTC time to local time in Azure Data Factory. This is useful when dealing with time zones.
The date time conversion concept is simple: you need to use the utcnow() function and specify the desired format. You can use the following table for conversion:
For example, to get the current date in 'dd-MM-yyyy hh:mm:ss' format, you can use the utcnow() function like this: utcnow( 'dd-MM-yyyy hh:mm:ss').
Getting Specific Date and Time Components
To get the current date and time in Azure Data Factory, you can use a code expression. This expression can be formatted to return specific date and time components.
You can specify the format to return the date with just the day using the 'D' format. For example, the expression 'D' returns the date as "Wednesday, September 01, 2021".
Current Month
Getting the current month in Azure Data Factory is a straightforward process. You can use the following code expressions to achieve this.
To get the full name of the current month, use the expression: "September". This will return the full name of the current month.
For the abbreviated name of the month, use the expression: "Sep". This will return the abbreviated name of the current month.
If you need the month as a number from 01 to 12, use the expression: "To get the current month(The month, from 01 through 12) in Azure data factory, you can use the following code expression:". However, this expression is not provided, so you'll have to figure out the correct syntax on your own.
Get Current Year
Getting the current year in Azure Data Factory (ADF) is a straightforward process. You can use the code expression to get the current year as a five-digit number.
To get the current year, you'll need to use the correct code expression, which depends on the desired format. The year as a five-digit number can be obtained using a specific code expression.
For example, if you want the year as a four-digit number, you'll need to use a different code expression. This is because ADF has different code expressions for different year formats.
The result of using the correct code expression will be the current year.
