SignalID | Automatic radio signal identification for Android and PC

I am using placeholder and also tried with tostring but it is not displaying the info in the alert message, What am I missing?

It's only displaying as is..

I have a TABLE1 table in which I am storing Signal_name, Timestamp, Signal_value. I am storing same 52 signals values at every 10 milliseconds(in every 10 milliseconds 52 values inserted into 52 columns of the table).

I want to get values in a time range between two dates and exclude some values in gaps between those two dates. My query works well with a small amount of gaps, however, sometimes I have to exclude a huge amount of gaps so that my query exceeds the maximum amount characters. Right now I'm concatenating EXCEPT queries for each time-gap I want to exclude. I'm sure there is some smarter way to do that, but I'm not so familiar with SQL.

I'm working with pandas read_sql() and passing the parameters with the params argument, in the example I wrote down readable values:

I am using Postgres and Sequelize to create a file that when called, creates an array of objects, which has 3034 separate items within it. I then pass this array to my model 'SignalDegs' with the call bulkCreate. As I watch node execute the file, from what it looks like all the items are being read within the function, the last line output is a console.log that I've written to confirm that an error was not caught.

After double-checking with my Postgres DB by selecting all records, I see that only the first 185 rows are written.

Is there a limit to how many records can be written with bulkCreate?

Function Call

Working on a small project where I need to populate a postgres database based on some log data. I've decided to use Sequelize to create my model and db connection.

When trying to call SignalDegs.create() to insert a record I receive the below error message. I've tried to reference DataTypes and import it instead of Sequalize directly resulting in the same error. Any help would be greatly appreciated!.
