Hi @sivaram_mandepu,

In the first screenshot, the input must be a valid JSON array, so instead of using {{mvname: "mv_......"}}, update it to [ { "mvname": "mv_......." } ].

In the third screenshot, the SQL error likely comes from a newline or extra space in the mv_name value. You can try trimming the value in Python using dbutils.widgets.get("mv_name").strip() before using it in the SQL command.

Let me know if this doesn’t work.
