我正在读取文本文件的整数, 把它们作为输入输入查询, 并将查询输出和写入到 xls 文件 。
ResultSet rs;
Connection con = null;
PreparedStatement ps = null;
int person_org_id, external_person_org_id;
File f = null;
Scanner scan = null;
try {
System.out.println("----------checkpoint-----------");
Class.forName("oracle.jdbc.driver.OracleDriver");
System.out.println("----------checkpoint 1-----------");
con = DriverManager.getConnection("jdbc:oracle:thin:@ksdjf.kjdlk.jkd.com:2222:edb", "aaaaa", "aaaa");
System.out.println("----------checkpoint 2 ----------");
if (con == null) {
System.out.println("unable to connect to database");
}
System.out.println("----------checkpoint 3::connected to database---------");
StringBuffer sql = new StringBuffer();
sql.append("select abd from edb.abd where customer_id=510 and person_org_id =? ");
ps = con.prepareStatement(sql.toString());
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("Excel Sheet");
HSSFRow rowhead = sheet.createRow(0);
rowhead.createCell(0).setCellValue("ABC");
rowhead.createCell(1).setCellValue("DEF");
f = new File("/tmp/contacts.txt");
scan = new Scanner(f);
int index=1;
while (scan.hasNextInt()) {
person_org_id = scan.nextInt();
ps.setInt(1,person_org_id);
rs= ps.executeQuery();
while (rs.next()) {
external_person_org_id = rs.getInt(1);
HSSFRow row = sheet.createRow(index);
row.createCell(0).setCellValue(person_org_id);
row.createCell(1).setCellValue(external_person_org_id);
index++;
}
}
FileOutputStream fileOut = new FileOutputStream(new File("/tmp/External_contact_id.xls"));
wb.write(fileOut);
fileOut.close();
System.out.println("--------checkpoint 4:: writing data to xls completed------------");
}
catch (Exception e) {
System.out.println(e.getMessage());
}
我得到的错误 Invalid 行号(65536)在允许范围外(0.65535)
我的 contacts.txt 文件有大约36000个数字。
