 Hello, welcome to SSUnitex. This is continuation of Azure Data Factory interview questions and answers. So recently one of my friend has attended interview in one of the organizations. So this question was asked there. So here we will see how to use the wildcard characters inside the get meta data activity. Because inside the get meta data activity we don't see any direct option by which we can use the wildcard characters. So let me quickly go inside the browser and we will try to see the requirement first. We are having all these files. Our requirement is we just want to pick only the file which is containing today's date 2205. So that we can see the third file and the last file. So these two files it will pick and will process. So this is the actual requirement. So let me quickly go inside the Azure Data Factory and here as I have already created this pipeline. So let's start. So first let me try to use the get meta data activity. So we can simply use the get meta data activity here. Go to on the settings and under the settings we are required to set up a data set. So let me try to create a new data set here as it is pointing to Azure Blob Storage. So you can select the Azure Blob Storage then click on continue. After that the file format which is the delimited text and click on continue. Now here we have already created the link service. So we can use that link service. Now let me try to select the path. So here we can select the input location and under the input we can see the India. So we should be having the India folder under the input. So we can go here and let me try to go inside the India. So without selecting any file you can simply click on OK. So all these files which is available under the India we want to pick. Now first row as header you can either select or skip then click on OK. So what it is doing it is going to create a new data set as data set is created. Let me click on this plus symbol and here which argument we want we want all the child items here. So this is we are having. But remember if we are going to execute this it will be going to get all the files those are available under the India folder. So we can hear verify the output. So in this child items we can see it is picking all these files. But we don't see any options by which we can mark this as dynamic. So we can open this data set so we cannot use the wildcard characters directly inside the path. So how we can use it so simply we can go inside the parameter and let's try to create a new parameter with the file name and go to the connection and trying to make this file name as dynamic and using this parameter of the file name. So now this data set is expecting one input parameter which will be the file name. But the file name we can go inside the pipeline and here this data set is asking this parameter value. So here we can use the wildcard characters. So simply we can use the astic 20205 then again astic. So if we are having any file that is containing 20205 it will pick all those files except those files it will not pick any file. So let me try to execute it again. So this time it should pick only two files. So as it got executed let me check the output. So here this time we can see it is only picking these two files because these two files are containing 20205. So I hope guys you have understand how we can use the wildcard characters inside the get metadata activity. Thank you so much for watching this video. See you in the next video.
