Question

我需要从我的数据库表中获取“Tname”列中具有相同值“r_c”的所有行。

 public ArrayList<String> getDb2(String r_c ){
    ArrayList<String> dd = new ArrayList<>();
    String KW = r_c.toString();
    String selection = "Tname " + "like ? ";

    Cursor cursor = db.query("info", null,selection,new String[]{"%"+KW+"%"},null,null,null);
    if(cursor !=null && cursor.moveToFirst()){
        do{
            dd.add(cursor.getString(0)+"\n " + "From :  " +cursor.getString(2)+"\n "+"price : " + cursor.getString(1)+" \n "+"Nots : " + cursor.getString(3));
        }
        while (cursor.moveToNext());
    }
    return dd ;
}

回答手机，对不起，如果代码中有任何错误，但想法很简单。

function manuf {
 echo -n "Manufacturer: " ; read userManuf
 varManuf=$(mysql -D snipeit -e "SELECT count(id) FROM manufacturers;")
 countManuf=$(echo $varManuf | awk '{print $2}')

 if [ $userManuf -ne 0 ] && [ $userManuf -le $countManuf ]; then
    assetModelManuf=$userManuf
 elif [ "$userManuf" = "n" ] || [ "$userManuf" = "N" ]; then
    echo -n "Type new manufacturer name: " ; read userNewManuf
    assetModelManuf=$userNewManuf
 else    echo "Try again!" && manuf
 fi
}

如何获取列中具有相同值的行列表？
