有人看到我的更新或插入查询有问题吗？我正在使用准备好的语句

Connection connection2 = UBOCMSSQLConnectionUtill.getMSSqlConnection();
connection2.setAutoCommit(false);
PreparedStatement updatePreparedStatement = null;
PreparedStatement insertPreparedStatement = null;
try {
    String updateQuery = \"UPDATE CRLM2 SET BR=?, LIMITTYPE =?, LIMITMEMBER=?,\"
        + \"PRODUCT=?,PRODTYPE=?,MTYDATE=?,CCY=?,CREQLIMAMT=?,MRKTLIMAMT=?,EXPDATE=?,\"
        + \"PRODGROUPID=?,AMT1=?,AMT2=?,DATE1=?,DATE2=?,TEXT1=?,TEXT2=?,LIMITSEQ=?,\"
        + \"STARTDATE=?,UPDATECOUNTER=? WHERE LIMITMEMBER = ?\";

    String insertQuery = \"insert into CRLM2(\" + \"BR,\" + \"LIMITTYPE,\"
        + \"LIMITMEMBER,\" + \"PRODUCT,\" + \"PRODTYPE,\" + \"MTYDATE,\"
        + \"CCY,\" + \"CREQLIMAMT,\" + \"MRKTLIMAMT,\" + \"EXPDATE,\"
        + \"PRODGROUPID\" + \"AMT1,\" + \"AMT2,\" + \"DATE1,\" + \"DATE2,\"
        + \"TEXT1,\" + \"TEXT2,\" + \"LIMITSEQ,\" + \"STARTDATE,\"
        + \"UPDATECOUNTER) \"
        + \"values(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)\";

     * then insert it.
