Import data from google sheets to a MySQL table

Saving data from Google. Sheets to MySQL table using Apps Script.

Prerequisites

• create a table in MySQL database
• A google sheet with data

MySQL table

CREATE TABLE `invoice` (
 `id` INT(11) NOT NULL AUTO_INCREMENT, 
 `headquarter` VARCHAR(90) NULL DEFAULT NULL, 
 `invoice_month` VARCHAR(90) NULL DEFAULT NULL, 
 `invoice_year` CHAR(4) NULL DEFAULT NULL, 
 `customer` CHAR(100) NULL DEFAULT NULL, 
 `invoice_no` VARCHAR(12) NULL DEFAULT NULL, 
 `invoice_value` VARCHAR(20) NULL DEFAULT NULL, 
  PRIMARY KEY (`id`)
)
;

Apps Script to insert data into MySQL

  var maxRecordsPerBatch = 1000;
  var spreadsheet = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = spreadsheet.getSheetByName(sheetName);
  var sheetData = sheet.getDataRange().getValues();
  var dbConnection = Jdbc.getConnection(url, username, password);

  // The following only needs to be set when you are changing the statement that needs to be prepared
  // or when you need to reset the variable.
  //
  // For example, if you were to switch to a different sheet which may have different values, columns,
  // structure, and/or target database table.

  var dbStatement = dbConnection.prepareCall(sql);

  var headquarter;
  var invoice_month;
  var invoice_year;

    // to the database for processing.
    dbStatement.addBatch();

      }
      if (!lastRow)
      { // Reset vars
        dbStatement = dbConnection.prepareCall( sql ); // Better to reset this variable to avoid any potential "No operations allowed after statement closed" errors
