For workflow definitions in Azure Logic Apps and Power Automatesome expressions get their values from runtime actions that might not yet exist when your workflow starts running. To reference these values or process the values in these expressions, you can use functions provided by the Workflow Definition Language.
Although this page refers specifically to logic apps, these functions work for both flows and logic apps. For more information about functions and expressions in Power Automate, see Use expressions in conditions. For example, you can calculate values by using math functions, such as the add function, when you want the sum from integers or floats. Here are other example tasks that you can perform with functions:.
Or, for detailed information about each function, see the alphabetical list. To show how to use a function in an expression, this example shows how you can get the value from the customerName parameter and assign that value to the accountName property by using the parameters function in an expression:.
For example, the concat function can take two or more string values as parameters. This function combines those strings into one string. You can either pass in string literals, for example, "Sophia" and "Owen" so that you get a combined string, "SophiaOwen":.
Or, you can get string values from parameters. This example uses the parameters function in each concat parameter and the firstName and lastName parameters. You then pass the resulting strings to the concat function so that you get a combined string, for example, "SophiaOwen":.

For example, see getFutureTime. The following sections organize functions based on their general purpose, or you can browse these functions in alphabetical order. To work with strings, you can use these string functions and also some collection functions. String functions work only on strings. To work with collections, generally arrays, strings, and sometimes, dictionaries, you can use these collection functions.
To work with conditions, compare values and expression results, or evaluate various kinds of logic, you can use these logical comparison functions. For the full reference about each function, see the alphabetical list. If you use logical functions or conditions to compare values, null values are converted to empty string "" values. The behavior of conditions differs when you compare with an empty string instead of a null value.Flow has a rich set of actions, but sometimes users just need to do basic operations like getting the current time, adding numbers together, or replacing a part of a string of text.
For new users who are unfamiliar with the expression language, there is an inline help experience that shows how to use each expression as they build out their flow.
On the Expression tab there is a list of the common expressions that are used inside of flows. When you select an expression, it will be added into the text box.
You will need to fill in the parameters for each expression that you use. You can now click on the expressions inside of the action card and they will open up again for further editing. Below are a few different scenarios for expressions. You can use the full list of functions available in the Azure Logic apps Workflow Definition Language, documented here.
One of the simplest examples for expressions is to manipulate dates. For example, using the new Get Calendar View action to get your events for the next day:. The utcnow expression gets the time that the flow runs at. Expressions like adddays or addhours can be used to add or subtract time — in this example, adding one day. You can see the various date formats here. Sometimes, you need to replace a certain character in a string. Replace takes three parameters: the string that you want to replace something in, the character you are replacing, and the character you want to replace it with.
A more involved scenario could be getting the extension from a file name.

This requires splitting the filename on the ". That would look like this: last split triggerOutputs ['headers']['x-ms-file-name'] ,'. In this example, the split function would return a list of each of the segments separated by the period. Then, the last function returns the final item in that list, which would be the file extension itself. One of the most advanced scenarios you can now use expressions for is Parsing XML messages.
First, you'll need to convert your content, be it from a file or some other API to be an XML inside of the flow engine.I am trying to auto mate a process such that two fields in a list are inputs from a flow copies the fields from another list and creates or updates this list B. Go to Solution. I have implemented a simulation of your flow by using a string variable called RandomCategory instead of triggerBody?
So, I guess the problem is when evaluating triggerBody? View solution in original post. If you could provide an expanded screenshot of your Flow and steps we could likely better assist you. If this reply has answered your question or solved your issue, please mark this question as answered. Answered questions helps users in the future who may have the same issue or question quickly find a resolution via search.
If you liked my response, please consider giving it a thumbs up. Step 1: just before your condition action block, create an array variable with the following pairs:. Step 2: Add a new Apply to Each inside the 'true' branch of your condition, using the variable you created as its input. Step 3: Include a condition inside the Apply to each, so you compare if triggerBody? If true, then invoke "Create item action block" using int last item as the input for "Annual leave allocated". Leave the 'false' branch empty.
Please remember to inspect all iterations of the Apply to Each loop to identify which one failed:. I just suggested to add the compose action block for troubleshooting purposes, so it is unclear to me why it is working now and failed before.
The Apply to each you added iterates over the array variable. So in its first execution it takes the first element from the array: ['C1','30'], the second time it takes the second element from the array: ['C2','25'], and so and so. Please note each element is also an array. In its first execution the expression first item extracts the first element from ['C1','30'] : the result is the string 'C1'. In its second execution the expression first item extracts the first element from ['C2','25'] : the result is the string 'C2'.
And so and so. In its first execution the expression last item extracts the first element from ['C1','30'] : the result is the string '30'. In its second execution the expression last item extracts the first element from ['C2','25'] : the result is the string '25'.Does alligator pepper help irrection in men

Re: Using if expressions in flow. Be grateful, Thumbs up!77mq css grid wrap
Save the Galaxy for free!In this walkthrough, you'll learn to use expressions and Conditions to compare multiple values in Advanced mode. When you create a flow, you can use the Condition card in basic mode to quickly compare a single value with another value.
However, there're times when you need to compare multiple values. For example, you may want to check the value of a few columns in a spreadsheet or database table.
Sometimes your workflow needs to take an action if the value of an item is valueA or valueB. For example, you may be tracking the status of tasks in a spreadsheet table.
Assume that the table has a column named Status and the possible values in the Status column are:. Given the preceding spreadsheet, you want to use Power Automate to remove all rows with a Status column that's set to completed or unnecessary.
Search for Scheduleand then select the Schedule - Recurrence trigger. Note: Select the "get rows" action that corresponds to the spreadsheet that you're using. Select the folder icon in the File name box, browse to, and then select the spreadsheet that contains your data.
Add the Value token to the Select an output from previous steps box. Add the following or expression. This or expression checks the value of each row in the table a row is known as an item when accessed in a expression. If the value of the status column is completed or unnecessarythe or expression evaluates to "true". In the File name box, search for, and select the spreadsheet file that contains the data you want to delete.
The flow runs after you save it. If you created the spreadsheet shown earlier in this walkthrough, here's what the it looks like after the run completes:. Notice all data from rows that had "completed" or "unnecessary" in the Status column were deleted. Assume you have a spreadsheet table with two columns. The column names are Status and Assigned. Assume also that you want to delete all rows if the Status column's value is "blocked" and the Assigned column's value is "John Wonder".
To accomplish this task, follow all steps earlier in this walkthrough, however, when you edit the Condition card in advanced mode, use the and expression shown here:.Go to Solution.
Can you please Try Below formula in Compose Connector, I reproduced your issue using this formula in compose connector and its working fine. View solution in original post. You can use condition connector for this purposeCondition Connector by default give you if condition functionality. No I can't use a condition - there is now where to add the condition in at the point where the issue arrises - the problem is like this. I wanted to put content in depending on what was on column 30, as part of the flow copy item from one sharepoint list to another.
So I have used expression, selected an logical expression if to asses column 30 and put certain info into [Primary Machine Process Instructions] column based on the assesment.
But the if statement as submitted it won't let me save the statement - what is it requiring to allow it to be valid? Find your favorite faces from the community presenting at the Power Platform Community Conference!
