Trouble reading data from MSSQL

Hi,
I am facing trouble in reading data from MSSQL server and displaying the same in a chart. Somehow could manage to program the "data to chart " node but not able to to make the query command work.
I am posting my flow.
Anticipating assistance, please.

I am trying to read data from a table named "trial" where the data pertains to a specific date and display the same in a chart.

  1. You need to specify the table name - you have used @input2 - this means select data from an in-memory table.
  2. do not surround a parameter with quotes.
  3. @input should be @input1

I am getting an error as given below;

I changed the data type to "datetime". Moreover I want to prefill the table name from the dropdown list "M/C" (and the date will be fed from the date picker - "date".)

For the table name, use mustache syntax as described in the built in help.

For the date time, make sure the input parameter is a date object.

Got it to work!!...thanks
