将值从一个db更新到另一个db时获取'com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException'

Question

我有两个数据库连接（broConn和zroConn），我正在将列值从第一个DB的一个表更新到第二个DB的相应表。两个表都具有相同的模式。

String sql = "select * From Personal_Info";
stmt = broConn.prepareStatement(sql);
ResultSet rs =  stmt.executeQuery(sql);
while (rs.next())
{
    String sql1 = "UPDATE personal_info SET Score = ?, Result = ?,
           ModifiedBy = ?, ModifiedDate = ?, StartDate = ?,
               EndDate = ?, UploadState = ?" + " WHERE CandidateID = ?";

    stmt = zroConn.prepareStatement(sql1);
    stmt.setInt(1, rs.getInt(8));
    stmt.setString(2, rs.getString(9));
    stmt.setString(3, rs.getString(15));
    stmt.setDate(4, rs.getDate(16));
    stmt.setDate(5, rs.getDate(17));
    stmt.setDate(6, rs.getDate(18));
    stmt.setString(7, rs.getString(19));
    stmt.setInt(8, rs.getInt(1));
    stmt.executeUpdate(sql1);
}

我在stacktrace中遇到错误 -
