Question

我有一个包含两列的表，如

VENDOR_NAME   DIRECTORY_NAME
DL_101Records  .ssh
DL_101Records  ADHOC
DL_101Records  ARCHIVED
DL_101Records  INBOUND
DL_101Records  OUTBOUND
DL_101Records  PROCESSED
DL_101Records  pub
DL_101Records  TAKEDOW

是否有一种简单的方法可以将其转换为单个字符串，如

VENDOR_NAME    DIRECTORY_NAME
DL_101Records  .SSH ,ADHOC ,ARCHIVED ,INBOUND ,OUTBOUND ,PROCESSED ,PUB ,TAKEDOWN

Answer 1

试试这个，

DECLARE @TEMP VARCHAR(MAX)='';
SELECT @TEMP=@TEMP+DIRECTORY_NAME+', ' FROM YOURTABLE
SELECT VENDOR_NAME,@TEMP FROM YOURTABLE
GROUP BY VENDOR_NAME

    @Override
    public void onBindViewHolder(final MyViewHolder holder, final int position) {
        final GetAdvReqPackagesListResponse.PackageList packageList1 = packageList.get(position);

        if (packageList.get(position).getSelection_flag().equals("1")) {
            subHolder.chkBoxSelectPackage.setChecked(true);
        } else {
            subHolder.chkBoxSelectPackage.setChecked(false);

        }


        holder.chkBoxSelectPackage.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {


        @Override
        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {


            if (isChecked == true) {
               //holder.chkBoxSelectPackage.setChecked(true);
               packageList.get(position).setSelection_flag("1");

                holder.textPackageCode.setTextAppearance(context, R.style.font_color_green_size_13sp);
                holder.textPackageDesc.setTextAppearance(context, R.style.font_color_green_size_13sp);
                holder.textLaborTU.setTextAppearance(context, R.style.font_color_green_size_13sp);
                holder.textLaborAmt.setTextAppearance(context, R.style.font_color_green_size_13sp);
                holder.textPartsCount.setTextAppearance(context, R.style.font_color_green_size_13sp);
                holder.textPartsAmt.setTextAppearance(context, R.style.font_color_green_size_13sp);
            } else if (isChecked == false) {
               // holder.chkBoxSelectPackage.setChecked(false);
                packageList.get(position).setSelection_flag("0");
                holder.textPackageCode.setTextAppearance(context, R.style.font_small_color_black_size_13sp);
                holder.textPackageDesc.setTextAppearance(context, R.style.font_small_color_black_size_13sp);
                holder.textLaborTU.setTextAppearance(context, R.style.font_small_color_black_size_13sp);
                holder.textLaborAmt.setTextAppearance(context, R.style.font_small_color_black_size_13sp);
                holder.textPartsCount.setTextAppearance(context, R.style.font_small_color_black_size_13sp);
                holder.textPartsAmt.setTextAppearance(context, R.style.font_small_color_black_size_13sp);


            }

            notifyDataSetChanged();             
    }
