I am using ADLS2 Storage for json files and am trying to read the file from serverless Synapse Analytics.
I can read the file using the normal means (SQL SCRIPT AND JSON_VALUE(doc, '$.date_rep') AS date_reported,) .
THE PROBLEM : The json file has [ ] wrapping the file contents. I cannot modify the files but cannot read using a query because the file is [] wrapped.
How do I remove the square brackets from the beginning and end of the json file in the query ( json_modify , ect)
Hi @MichaelColeman-6206
Are you able to use jq to unwrap the json?
eg:
json-and-jq
If this helps please accept my solution and upvote.
Or just have a nice day.
Hi @MichaelColeman-6206,
Welcome to Microsoft Q&A platform and thanks for posting your query.
As I understand your requirement here, you want to remove the square brackets from start and end of the JSON content. As you mentioned you are using Azure syanpse analytics , I hope you can leverage Syanpse pipelines in order to achieve the requirement.
You can follow the below steps :
Step1: Create a dataset pointing to the json file in ADLS.
Step2: Use LookUp activity in Synapse pipeline and use the newly created dataset in the lookup to fetch the JSON content as the LookUp output.
Step3: Create a variable in the pipeline say myvar and pass the following expression in its value: @substring(string(variables('var')),add(indexof(variables('var'),'"'),1),add(lastindexof(variables('var'),'"'),-2)) .
Output of the set variable activity will replace the brackets of the source JSON .
Hope this will help. Please let us know if any further queries.
