参数面板自定义按钮，添加点击事件，绑定js，js里写了调用数据库存储过程的代码：

var sql = "exec LXGW_CustMtl_PDPackInfo_Sync '" + fbillnos[0] + "','','','','','','','','','','',0,0,0,0,'','','','','',''";
FR.remoteEvaluate('=SQL("LXGW_SPECIAL_KFMIC","'+sql+'",1,1)');

存储过程是一个简单的测试存储过程， 内部接收到参数后只有一个insert语句：

INSERT INTO KFMI_CUSTMTL_PDPACKINFO(
	pdname,
	fbillno,
	planneddateto,
	custpo,
	endcustnumber,
	endcustname,
	endcustshortname,
	kfmimtlnumber,
	kfmimtlname,
	kfmimtlmodel,
	kfmicodeno,
	pdqty,
	fqty,
	netweight,
	grossweight,
	volume,
	grossweightdetail,
	volumedetail,
	packagingmethod,
	packagingno,
	totalpackages,
	coapages,
	salesdd,
	salesddhrid,
	csdd,
	csddhrid,
	xxms,
	bsxz
	) VALUES(
	@pdname,
	@fbillno,
	@planneddateto,
	@custpo,
	@endcustnumber,
	@endcustname,
	@endcustshortname,
	@kfmimtlnumber,
	@kfmimtlname,
	@kfmimtlmodel,
	@kfmicodeno,
	@pdqty,
	@fqty,
	@netweight,
	@grossweight,
	@volume,
	@grossweightdetail,
	@volumedetail,
	@packagingmethod,
	@packagingno,
	@totalpackages,
	@coapages,
	@salesdd,
	@salesddhrid,
	@csdd,
	@csddhrid,
	@xxms,
	@bsxz
	)
