How to write a query for AFTER DATE

Hello Experts,
I’m new to SQL and stuck on a query. How would you write SQL Code for the following query:
The HR Department wants to determine the names of all employees who were hired after Davies:
Thanks in advance.

Hello,
You need to change to the table name you have in your schema and in this case its "employees". Don't hard code date in where clause you might have different requirement later ;)
SELECT *
FROM employees
WHERE hire_date > (SELECT hire_date
FROM employees
WHERE name = 'Davies');Regards

12-jan-89         Thusrs_day

No not like that ,I want up to 2014 year
Ok, so lets say you have table like this
SQL> create table my_table(dob date);
Table created.
SQL> insert into my_table (dob) values( to_date('12-jan-1989', 'dd-mon-yyyy'));
1 row created.
SQL> commit;
Commit complete.
SQL> select * from my_table;
DOB
12-JAN-89
You can write a query like this
select dob + (level -1) dob
      , to_char(dob + (level -1), 'fmDay') day_
   from my_table
connect
     by level <= (dob + interval '25' year) - dob + 1;

How to write sql query for counting pairs from below table??

Below is my SQL table structure.
user_id | Name | join_side | left_leg | right_leg | Parent_id
100001 Tinku Left 100002 100003 0
100002 Harish Left 100004 100005 100001
100003 Gorav Right 100006 100007 100001
100004 Prince Left 100008 NULL 100002
100005 Ajay Right NULL NULL 100002
100006 Simran Left NULL NULL 100003
100007 Raman Right NULL NULL 100003
100008 Vijay Left NULL NULL 100004
It is a binary table structure.. Every user has to add two per id under him, one is left_leg and second is right_leg... Parent_id is under which user current user is added.. Hope you will be understand..
I have to write sql query for counting pairs under id "100001". i know there will be important role of parent_id for counting pairs. * what is pair( suppose if any user contains both left_leg and right_leg id, then it is called pair.)
I know there are three pairs under id "100001" :-
1. 100002 and 100003
2. 100004 and 100005
3. 100006 and 100007
100008 will not be counted as pair because it does not have right leg..
But i dont know how to write sql query for this... Any help will be appreciated... This is my college project... And tommorow is the last date of submission.... Hope anyone will help me...
Suppose i have to count pair for id '100002'. Then there is only one pair under id '100002'. i.e 100004 and 100005

Sounds like this to me
DECLARE @ID int
SET @ID = 100001--your passed value
SELECT left_leg,right_leg
FROM table
WHERE (user_id = @ID
OR parent_id = @ID)
AND left_leg IS NOT NULL
AND right_leg IS NOT NULL

In general case, you cannot write this query.
This is one of the limits of relational database concepts. The number of columns must be known up-front. In the SELECT clause, you have to list and name all columns returned by the query. So you have to know number of departments. (There are some workarounds - you can return one column with concatenated values for all departments, separated by space character).
If you know that you have 3 departments then you qurey will return 4 columns:
SELECT
   e.job,
   SUM ( CASE WHEN d.deptid = 10 THEN e.sal ELSE NULL END) d10,
   SUM ( CASE WHEN d.deptid = 20 THEN e.sal ELSE NULL END) d20,
   SUM ( CASE WHEN d.deptid = 30 THEN e.sal ELSE NULL END) d30
FROM dept d, emp e
WHERE d.deptno = e.deptno
GROUP BY e.job

How to write select query for this

Hi,
I had a html form and in the for i had drop down box and it needs to select multiple values from the drop down box. When i select multiple values then i have to write the SQL select statement query .
When i try to write the select statement and trying to run i am getting error.
select * from Table
where emo_no = '1,2,3'
this is how i write query please suggest me how to write query for selecting multiple values from the drop down box.
Thanks

select * from Table
where emo_no in ( 1,2,3)
for integer values
select * from Table
where emo_no in ('1','2','3')
for characters
If we talk about large scale applications that may have millions of records, I would suggest this.
declare @t table (v int)
insert into t (v) values (1)
insert into t (v) valves (2)
insert into t (v) values (3)
select *
from table
inner join @t t on table.emo_no = t.v
Using "in" for a where clause is not so bad for filtering on a few values, but if you are filtering a lot of rows and a lot of values (emo_no) the performance degrades quickly for some reasons beyond the scope of this.
This is just one solution, I'll through this out as well, instead of an in memory (@t) table, doing a disk based temp table (#t) and creating an index on the column "v".
create table #t (v int)
insert into #t (v) values (1)
insert into #t (v) valves (2)
insert into #t (v) values (3)
create index ix_t on #t (v)
select *
from table
inner join #t t on table.emo_no = t.v
drop table #t
Pardon any syntax errors and careful using a drop statement.
Sometimes in memory tables work better than disk temp tables, it takes some testing and trial and error depending on your datasets to determine the best solution.
Probably too much info ;-)

Assuming you're using SQL Server you can ask here:
http://www.sqlteam.com/forums/forum.asp?FORUM_ID=23
Otherwise, please ask in the relevant forum for the type of technology you're using.
Basically it's either:
select *
from [table name]
order by country
If you want to do something with groups do something like:
select (max) income, country
from [table name]
group by country
