Azure Data Factory - Lookup Activity: Filtering Azure Table Storage query with In operator

Question

I created a Azure Table storage with this format:

ID	Table
1	table1
2	table2
3	table3
4	table4

and in the DataFactory I want to create a query using this table filtering with the IN operator, for example: ID in ('1', '2')

I'm using a Lookup Activity and I created this array parameter: array parameter

and I want to use it in the query, for example: @ID in pipeline().parameters.Id image: data factory - lookup activity query

Does anyone know a way to filter and help? Thanks!

AFAIK , Currently IN and Contains are not supported in Azure Table Storage Queries.

If your array values are less, you can directly give the query like Id eq '1' or Id eq '2' in lookup which will give the following result.

If your array is large, you can try the below approach using a ForEach.

Lookup activity:

ForEach:

Give the Lookup output value.

Inside ForEach Store the item() in a variable as string:

Inside if condition give the following expression:

@contains(pipeline().parameters.arr,item().Id)

Here arr is an array parameter with ["1","2"] values.

In true activities append the Variable value to an array variable:

Result stored in another variable from res1 variable (optional and only for showing result here):
