I have a table like below,I'm using vertica data base sql
| Name | Cust ID |
| | 1 |
| | 2 |
|Prem | 2 |
For cust ID 1 the name is blank, so it should display and N/A, for cust ID 2 we have 2 entries, which are 1 is blank and 2 is Prem, so blank should be ignored and should display Prem.
The final out put should be like this,
|Name | Cust ID |
|N/A |1 |
|Prem |2 |
The final output should be like this,
|Name | Cust ID |
|N/A |1 |
|Prem |2 |
This works if the non-empty name of the same cust-id is always the same in multiple rows. Note that I use the NULL value for non-existent data. An empty string and NULL are two different things, for me.
WITH
indata("name",custid) AS (
SELECT NULL , 1
UNION ALL SELECT NULL , 2
UNION ALL SELECT 'Prem', 2
)
SELECT
IFNULL(MAX("name"),'N/A') AS "name"
, custid
FROM indata
GROUP BY custid;
-- out Null display is "(null)".
-- out name | custid
-- out ------+--------
-- out N/A | 1
-- out Prem | 2
I have this written and working as a raw SQL query, but I am trying to convert it to a more Laravel eloquent / query builder design instead of just a raw query.
My table structure like this:
Table One (Name model)
______________
| id | name |
|------------|
| 1 | bob |
| 2 | jane |
--------------
Table Two (Date Model)
_________________________________
| id | table_1_id | date |
|-------------------------------|
| 1 | 1 | 2000-01-01 |
| 2 | 1 | 2000-01-31 |
| 4 | 1 | 2000-02-28 |
| 5 | 1 | 2000-03-03 |
| 6 | 2 | 2000-01-03 |
| 7 | 2 | 2000-01-05 |
---------------------------------
I am returning only the the highest (most recent) dates from table 2 (Dates model) that match the user bob from table 1 (Name model).
For instance, in the example above, I return this from my query
2000-01-31
2000-02-28
2000-03-03
Here is what I am doing now (which works), but i'm just not sure how to use YEAR, MONTH and MAX with laravel.
DB::select(
DB::raw("
SELECT MAX(date) as max_date
FROM table_2
INNER JOIN table_1 ON table_1.id = table_2.table_1_id
WHERE table_1.name = 'bob'
GROUP BY YEAR(date), MONTH(date)
ORDER BY max_date DESC
")
);
Try this code if any problem then,
DB::table('table_1')->join('table_2', 'table_1.id','=','table_2.table_1_id')
->select(DB::raw('MAX(date) as max_date'),DB::raw('YEAR(date) year, MONTH(date) month'),'table_1.name')
->where('name','bob')
->groupBy('year','month')
->orderBy('max_date')
->get();
If any problem with above code then feel free to ask.
I have a SQL Server table like this

| | John | 2/6/2016 |
| | John | 4/6/2016 |
| | John | 4/6/2016 |
| | Andi | 5/6/2016 |

+----+-----------+------------+
i want insert the id coloumn like this.
+-----------+-----------+------------+
| id | acoount | date |
+-----------+-----------+------------+
| 020616001 | John | 2/6/2016 |
| 020616002 | John | 2/6/2016 |

| 040616003 | Steve | 4/6/2016 |
+-----------+-----------+------------+
I want to generate id number of the date provided like this. 02+06+16(from date)+001 = 020616001. if have same date, id + 1.
I have tried but still failed .
I want make it in oracle sql develop.
Someone help me.
Thanks.
Try the below SQL as per the given data, Its in SQL Server 2012....
select REPLACE(CONVERT(VARCHAR(10),convert(date,t.[date]), 101), '/', '')
+'00'+convert(varchar(2),row_number()over(partition by account,[date] order by t.[date])) as ID,
t.account,
t.date
from (values ('John','2/6/2016'),
('John','2/6/2016'),
('John','4/6/2016'),
('John','4/6/2016'),
('Andi','5/6/2016'),
('Steve','4/6/2016'))T(account,[date])
Update your table using statement .
update table set id= replace(CONVERT(VARCHAR(10),CONVERT(datetime ,date,103),3) ,'/', '') + Right('00'+convert(varchar(2),row_number()over(partition by account,[date] order by t.[date])) ,3)
MySql
i can give you the logic of 020616001 this part right now .......
for same id +1 i have to work on it....that i ll let u know after my work
insert into table_name(id)
select concat
(
if(length (day(current_date))>1,day(current_date),Concat(0,day(current_date))),
if(length (month(current_date))>1,month(current_date),Concat(0,month(current_date))),
(right(year(current_date),2)),'001'
)as id
you cannot convert your dates column to datetime type in normal way because it is dd/mm/yyyy.
Try this,
declare #t table(acoount varchar(50),dates varchar(20))
insert into #t values
('John','2/6/2016')
,('John','2/6/2016')
,('John','4/6/2016')
,('John','4/6/2016')
,('Andi','5/6/2016')
,('Steve','4/6/2016')
;With CTE as
(select * , SUBSTRING(dates,0,charindex('/',dates)) dd
,SUBSTRING(stuff(dates,1,charindex('/',dates),''),0, charindex('/',stuff(dates,1,charindex('/',dates),''))) MM
,right(dates,2) yy
from #t
)
,CTE1 as
(
select *
,ROW_NUMBER()over(partition by yy,mm,dd order by yy,mm,dd)rn from cte c
)
select *, REPLICATE('0',2-len(dd))+cast(dd as varchar(2))
+REPLICATE('0',2-len(MM))+cast(MM as varchar(2))
+yy+REPLICATE('0',3-len(rn))+cast(rn as varchar(2))
from cte1
I have got a table with name table_listnames whose structure is given below
mysql> desc table_listnames;
+-------+--------------+------+-----+---------+----------------+
| Field | Type | Null | Key | Default | Extra |
+-------+--------------+------+-----+---------+----------------+
| id | int(11) | NO | PRI | NULL | auto_increment |
| name | varchar(255) | NO | | NULL | |
+-------+--------------+------+-----+---------+----------------+
2 rows in set (0.04 sec)
It has got sample data as shown
mysql> select * from table_listnames;
+----+------------+
| id | name |
+----+------------+
| 6 | WWW |
| 7 | WWWwww |
| 8 | WWWwwws |
| 9 | WWWwwwsSSS |
| 10 | asdsda |
+----+------------+
5 rows in set (0.00 sec)
I have a requirement where if name not found under the table , i need to insert or else do nothing
I am achieving it this way
String sql = "INSERT INTO table_listnames (name) SELECT name FROM (SELECT ?) AS tmp WHERE NOT EXISTS (SELECT name FROM table_listnames WHERE name = ?) LIMIT 1";
pst = dbConnection.prepareStatement(sql);
pst.setString(1, salesName);
pst.setString(2, salesName);
pst.executeUpdate();
Is it possible to know the id of the record of the given name in this case
I have one table like this (report)
--------------------------------------------------
| user_id | Department | Position | Record_id |
--------------------------------------------------
| 1 | Science | Professor | 1001 |
| 1 | Maths | | 1002 |
| 1 | History | Teacher | 1003 |
| 2 | Science | Professor | 1004 |
| 2 | Chemistry | Assistant | 1005 |
--------------------------------------------------
I'd like to have the following result
---------------------------------------------------------
| user_id | Department+Position |
---------------------------------------------------------
| 1 | Science,Professor;Maths, ; History,Teacher |
| 2 | Science, Professor; Chemistry, Assistant |
---------------------------------------------------------
That means I need to preserve the empty space as ' ' as you can see in the result table.
Now I know how to use LISTAGG function but only for one column. However, I can't exactly figure out how can I do for two columns at the sametime. Here is my query:
SELECT user_id, LISTAGG(department, ';') WITHIN GROUP (ORDER BY record_id)
FROM report
Thanks in advance :-)
It just requires judicious use of concatenation within the aggregation:
select user_id
, listagg(department || ',' || coalesce(position, ' '), '; ')
within group ( order by record_id )
from report
group by user_id
i.e. aggregate the concatentation of department with a comma and position and replace position with a space if it is NULL.
