What is the best way to go about reading the .txt file and executing the query to add the records?

I have a .txt file containing an insert query with around 10,000 records. Below is an example:

INSERT INTO tblVeiculo (VeiculoId, Codigo, Fabricante, Modelo, AnoInicial, AnoFinal, Portas, Combustivel, NrMotorObstruido) VALUES
(1, '001034066', 'AGRALE', 'MT 12.0 4X2 SB(E-TRONIC)(URB.) DIES 2P BASICO', 2005, 2013, 2, 'DIES', 1), 
(2, '001034078', 'AGRALE', 'MT 12.0 4X2 LE(E-TRONIC)(RODOV.) DIES 1P BASICO', 2005, 2013, 1, 'DIES', 0), 
(3, '001034080', 'AGRALE', 'MT 12.0 4X2 LE(E-TRONIC)(RODOV.C/AR) DIES 1P BASICO', 2005, 2013, 1, 'DIES', 0), 
(4, '001034091', 'AGRALE', 'MT 12.0 4X2 LE(E-TRONIC)(URBANO) DIES 2P BASICO', 2005, 2013, 2, 'DIES', 0) ...

I need to extract the data from this .txt file and execute the query to insert all the records into an SQLite database.

The table I am trying to create looks like this:

db.openDatabase({
  name: "data.db",
  location: "default"
}).then(() => {
  db.executeSql("CREATE TABLE IF NOT EXISTS tblVeiculo ("
    + "VeiculoId INTEGER        PRIMARY KEY AUTOINCREMENT NOT NULL,"
    + "Codigo VARCHAR (512), "
    + "Fabricante VARCHAR (256), "
    + "Modelo VARCHAR (512), "
    + "AnoInicial DATETIME, "
    + "AnoFinal DATETIME, "
    "[Portas] INT (1), "
    + "Combustivel VARCHAR (256), "
    + "[NrMotorObstruido] INT (1)); ", {}).then((data) => {
      console.log("TABLE CREATED: ", data);
    }, (error) => {
      console.error("Unable to execute sql teste", error);
    })
}, (error) => {
  console.error("Unable to open database", error);
});

Is there a way to read the content of the .txt file and execute the insert query in SQLite?

Answer №1

It's interesting that this question is related to Angular2 considering the usual process of reading a text file and inserting it into SQL server happens on the backend.

This operation is typically done when the backend starts up.

If you do want to read a text file in Angular2, you would first need to use the http service to load it. However, trying to communicate with SQL from the client side could pose security risks as your code would be visible to anyone who accesses it.
