Export new added row from global table to SQL database

farah_a — Wed, 25 Mar 2020 15:48:45 GMT

Greeting everyone,

I have built a model in which I add rows and columns in a global table using process flow.

I want to export the added row simultaneously in my sql table, this means each time a row is added in my global table, it should be added at the same time in my database.

My question is how can i automatically export the data without having to do it manually from DBconnector ? what trigger is needed ?

i have basic knowledge in sql, which query can help me do that ?

Thank you for your help folks

Hi @Farah A,

To add a new column, I think you could execute SQL code like what's below:

ALTER TABLE MyTable
ADD NewColumn varchar(255);

You would just execute it at the same time the new column is created. I'm not entirely sure the best way to do this, though. It's just an idea.

As for automatically exporting all this data, you might look at this question or at the User Manual section entitled, "Excel Interface".

No trigger is going to fire when you add a row to a global table. If you want to export after adding the row, then you need to adjust your code everywhere you add a row to add the row and then also export.

You could wrap those two operations together into a user command if you wanted.

That error means exactly what it says:

Data type Database.DataType does not support property Integer.

You have to use one of the values available in Database.DataType. Database.DataType.Integer isn't in that list. Database.DataType.Int is. Depending on how your database is configured, you might need SmallInt, BigInt, or Numeric for that field.

Also, why are you calling con.disconnect() from that code when you aren't calling connect() from that code?

@phil.bobo does not the command Database.Connection con = Database.Connection("DBConnector1"); do the connection with database ?

@Farah A

That creates an instance of the Database object. You still need to call the connect method to establish a connection. There is an example here in the documentation:

Hi @Farah A,

Do you still need help with this?

Thanks @Benjamin W2 for your consideration,this code worked well for me to write in MysqlDatabase :

Database.Connection con = Database.Connection("DBConnector1");

con.connect();

Database.PreparedStatement statement = con.prepareStatement("INSERT INTO Table1 (id) VALUES (:id )");

statement.bindParam("id", Table("Date DG")

[1], Database.DataType.Int);

statement.execute();

con.disconnect();
