java导出MS sqlserver的某表数据
java导出MS sqlserver的某表数据
遇到一Linux系统的Jboss的java环境连MS sqlserver的数据库,想要导出某表数据存为csv文件,用java实现如下:
import java.io.BufferedOutputStream;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
import java.io.PrintStream;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;public class SqlServerDataDump {
public static void main(String[] arg){
SqlServerDataDump sqlDump = new SqlServerDataDump();sqlDump.dataDump();
}public void dataDump() {
final String databaseName = "dbname";
final String userName = "sa";
final String passWord = "passwd";
final String serverHost = "192.168.1.10";
final int serverPort = 1433;final String fileName = "/home/test/test.csv";
// Create a variable for the connection string.
final String connectionUrl = "jdbc:sqlserver://" + serverHost + ":"
+ serverPort + ";database=" + databaseName + ";user="
+ userName + ";password=" + passWord+";selectMethod=cursor";// Declare the JDBC objects.
Connection con = null;
Statement stmt = null;
ResultSet rs = null;final String querySql = "select * from user";
File outputFile = new File(fileName);
PrintStream printStream = null;
// if (!outputFile.isFile() || !outputFile.canWrite()) {
// // is dir or readonly
// return;
// }try {
printStream = new PrintStream(outputFile);
Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
con = DriverManager.getConnection(connectionUrl);
System.out.println("get connection success.");
stmt = con.createStatement();
rs = stmt.executeQuery(querySql);
System.out.println("dump data begin.");while (rs.next()) {
String col1 = rs.getString(1);
String col2 = rs.getString(2);
String col3 = rs.getString(3);
String col4 = rs.getString(4);
String col5 = rs.getString(5);
String col6 = rs.getString(6);
String col7 = rs.getString(7);
String col8 = rs.getString(8);
String col9 = rs.getString(9);
String col10 = rs.getString(10);
String col11 = rs.getString(11);
String col12 = rs.getString(12);
String col13 = rs.getString(13);
String col14 = rs.getString(14);
String col15 = rs.getString(15);
String col16 = rs.getString(16);
String col17 = rs.getString(17);
String col18 = rs.getString(18);
String col19 = rs.getString(19);
String col20 = rs.getString(20);
…………………………………..printStream.println(col1 + "," + col2 + "," + col3 + "," + col4 + "," + col5 + "," + col6 + "," + col7 + "," + col8 + "," + col9 + "," + col10 + "," + col11 + "," + col12 + "," + col13 + "," + col14 + "," + col15 + "," + col16 + "," + col17 + "," + col18 + "," + col19 + "," + col20 + "," + ………..);
}System.out.println("end dump data.");
} catch (Exception e) {
e.printStackTrace();} finally {
if (null != rs) {
try {
rs.close();
