做按组织关系汇总功能时，当数据量特别大，或者汇总组织特别多时，运行效率特别低，于是使用了merge into语句。
代码如下：
public void updateInsertData(DataSet dsl, String mxnm, DataSet dsc, DataSet dsr, String faslnm, DataSet dyxjDs, String thisBbnm, String tabname, DataSet glDs,String flnm,String dyzzNm,int hzbbStat){
//using后的sql

StringBuffer updateInsertSql = new StringBuffer();
SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss ");
String createdTime = formatter.format(new Date());
String lastmodifiedTime = formatter.format(new Date());
String creator = GetBspInfo.getBspInfo().getUserId();
updateInsertSql.append("MERGE INTO FCDATA_"+mxnm +" DA ");
updateInsertSql.append("USING ("+queryDataSql + ") QU ");
updateInsertSql.append("ON (");
for (int y = 0; y < dsl.getCount(); y++) {

if(!("ZZ".equals(wdmc))) {
