Question

例如

  public void invoke(String value, SinkFunction.Context context) throws SQLException {
    statement_.execute("INSERT INTO test (column_1) VALUES '"+value"');
  }

如何正确插入值？

Answer 1

建立连接后，您可以这样做：

String sql = "INSERT INTO test (column_1) VALUES (?)";
PreparedStatement statement = connection.prepareStatement(sql);
        
statement.setString(1, value);
statement.addBatch();
statement.executeBatch();
