Azure Synapse Analitycs Dynamic Content Expressions

Question

Hello, I have a problem with wanting to formulate a json expression using the expressions of synapse analitycs.

The expression is as follows: {"query": "SELECT TOP 1000 * FROM LN_tdsls401 WHERE infor.lastModified() > '2021-08-28T06:00:00Z'"}

@markus.bohland@hotmail.de ('{', '"entidad"',':','"LN_tdsls401"', ',', '"cantidad"',':','"1000"', '"query"',':', '"SELECT TOP 1000 * FROM LN_tdsls401 WHERE infor.lastModified() >','''',variables('lastupdated'),'''"}')

When running the pipeline I realize that it is not well formulated.

Hello @Anonymous ,
Thanks for the ask and using Microsoft Q&A platform .
As we understand the ask here is how to convert the string to a valid JSON . Please do let me know if that not accurate
As I understand at this time you are concatinating the string to create a JSON format . Just wanted to check if you have explored the option to use the JSON function . Please read about the same here .

Adding the text from the link above for more context .

****json****

Return the JavaScript Object Notation (JSON) type value or object for a string or XML.

Please do let me if you have any queries .
Thanks
Himanshu
