Join two table and fetch data!


HOME ยป Databases
I have two table and want to fetch data from them.
This query
working fine:
"Select * from myads join users on myads.id =
users.id";
but the problem is I want to use one of the field as
counter
For the Single table this works for me:
"SELECT
*,(30-DATEDIFF(now(),updateDate)) as counter FROM myads";
Now, my
question is how can i combine this two querys.. any help will be
helpful.

I am new in SQL server database, I want to know how to fetch
table data like in oracle I login through SQL , connect to the schema
and run select statement. Can someone provide me any link to learn
this.
Thanks

Good Day Everyone..

Table1 with thousand over
records various types of recurrance and due pattern.

/>where ID = History_ID

Table 1

Duepattern
1 Monthly 10
2 Yearly 25 />3 Monthly 15
4 Weekly
5 yearly
14


Table 2

I have two table of numbers. I need to join them sequentially. I
am looking for the most efficient way to do this. Actually. I am
working with dates but I will explain with numbers for simplicity.



TABLE 1 has data 1, 3, 6, 8
TABLE 2 has data 1.1, 2.3, 4.5, 6.5, 8.8, 8.9


I want values >= 1 and < 3 ... >= 3 and < 6 ... >=6 < 8
etc



I want a result like



1 1.1    
1 2.3
3 4.5
6 6.5
8 8.8
8 8.9


So, basically I want the values >= my current row but < then
next higher row.



I need this to be very efficient because it will be run on a large
dataset using dates instead of numbers.

My query looks like this:



@Query("SELECT p FROM Pilot p LEFT JOIN FETCH p.playerShips
WHERE p.nickname = (:nickname)")


So far so good. I'm getting Pilot instance even when playerShips is
empty.

Now, I want to fetch only inactive ships so I modified my query to
look like this:



@Query("SELECT p FROM Pilot p LEFT JOIN FETCH p.playerShips
s WHERE p.nickname = (:nickname) AND s.active = false")


and I'm getting null as a pilot so it clearly doesn't work.
I'd
be glad if someone could explain me how to create a JOIN FETCH query
with WHERE clause that applies to the child elements. Thanks in
advance.

I am fetching data from cursor in the way like this:



variable rc refcursor
spool file.txt
set timing on
exec :rc := someoraclepackage.somefunction(some,parameters,here)
set timing off
print rc
spool off


But I've identified a problem with TIMING. Some
packages give me the real time of their execution, but some other not.
They show me time like 120 miliseconds, and the real time of
processing the package is for example 10 minutes.



I need the exact time of the package processing for performance
testing.



All I have heard about the solution of this problem is:




  1. Inserting the data from the cursor to a temporary table (database
    server side), to count the real package runtime.

  2. Running a select * on the temporary table to fetch
    the data (jenkins side)



But I have no Idea where to start with putting the data from the
cursor to a temporary table, and I don't know if this is the real
solution of the problem...
