When you open each report after the weekly refresh, the reports are ready for delivery. For each web query, you set up an Excel spreadsheet that automatically refreshes every week.

Finally, we measure the time it takes to complete the reading and inserting of data.Run this program and you would see the output somehow like this: Import done in 3462 msTo verify, run SQL Select statement in MySQL Workbench and you would see: That’s how to write Java code that imports data from an Excel file and insert into database.
#EXCEL IMPORT XML DATA EXCEL GENERATES A TABLE UPDATE#
}As you can see, we use JDBC batch update feature to efficiently insert a large number of rows into the database, with batch size of 20 – which means it will group maximum 20 SQL statements in each batch sent to the server for processing.We also use JDBC transaction to make sure that either all rows inserted or none. ("Import done in %d ms\n", (end - start)) Int progress = (int) nextCell.getNumericCellValue() tTimestamp(2, new Timestamp(enrollDate.getTime())) String name = nextCell.getStringCellValue() ĭate enrollDate = nextCell.getDateCellValue() Int columnIndex = nextCell.getColumnIndex() Iterator cellIterator = nextRow.cellIterator() RowIterator.next() // skip the header row PreparedStatement statement = connection.prepareStatement(sql) String sql = "INSERT INTO students (name, enrolled, progress) VALUES (?, ?, ?)" Iterator rowIterator = erator() Ĭonnection = DriverManager.getConnection(jdbcURL, username, password) Sheet firstSheet = workbook.getSheetAt(0) Workbook workbook = new XSSFWorkbook(inputStream) String jdbcURL = "jdbc:mysql://localhost:3306/sales" įileInputStream inputStream = new FileInputStream(excelFilePath) * Sample Java program that imports data from an Excel file to MySQL database.

Suppose that your project uses Maven, so add the following dependency to the pom.xml file: Īnd to insert data to MySQL database from Java, we need to use a dependency for MySQL JDBC driver: Īnd below is the full code of the sample program that reads data from the Excel file and insert that data to MySQL database: package net.codejava ) Note that the data type of the enrolledcolumn is timestamp so it can hold both date and time values.To read the Excel file from Java, we can use the Apache POI library. So let’s create a corresponding table in the database with the following structure: You can run the following MySQL script to create this table: CREATE TABLE `students` ( So in this post, I will share with you a sample Java program that reads data from an Excel file and inserts that data to a MySQL database.Suppose that we have an Excel file that stores information about students enrolled in courses like this: As you can see, this Excel file has only one sheet and the student information is stored in 3 columns: Student Name (text), Enrolled (date time) and Progress (number).
