您如何使用 jdbc 执行此类操作?
String x = ("\\. /home/user/Desktop/dbfile.sql");
Class.forName(Database.JDBC_DRIVER);
Connection conn = (Connection) DriverManager.getConnection(
Database.DB_URL + "localhost" + "/" + "mydatabase", "root", "");
Statement stmt = (Statement) conn.createStatement();
stmt.execute(x);
结果:线程“main” com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException 中的异常:您的 SQL 语法有错误;检查与您的 MySQL 服务器版本相对应的手册,以了解在 '.
我试过这个
public static void main(String[] args) throws Exception
{
String x = readFileAsString("/home/user/Desktop/myDB.sql");
Class.forName(Database.JDBC_DRIVER);
Connection conn = (Connection) DriverManager.getConnection(
Database.DB_URL + "localhost" + "/" + "mydb", "root", "");
Statement stmt = (Statement) conn.createStatement();
System.out.println(x);
stmt.execute(x);
}
private static String readFileAsString(String filePath) throws Exception
{
byte[] buffer = new byte[(int) new File(filePath).length()];
BufferedInputStream f = null;
try
{
f = new BufferedInputStream(new FileInputStream(filePath));
f.read(buffer);
}
finally
{
if (f != null)
try
{
f.close();
}
catch (IOException ignored)
{
}
}
return new String(buffer);
}
结果
Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS */;
