SQL>You can see that the bytes representing each characters have numeric values, and it each of these that are compared from left to right. 'john' starts with a 'j' which is 106 and that's greater than 97 or 102, so john is the greatest.
If there were two names beginning with 'j' then the next character is compared...

How to retrieve Min(startDate) and Max(endDate) for different groups of data? (sql server 2000)

My sample dataset (below) contains 3 groups -- 'a', 'b', 'c'. I need to retrieve the Min(startDate) and Max(EndDate) for each group so that the output looks something like this (date format not an issue):
fk   minStart      maxEnd
a    1/13/1985    12/31/2003
b    2/14/1986    12/31/2003
c    4/26/1987    12/31/2002
What is the Tsql to perform this type of operation? Note: the actual data resides in a sql server 2000 DB. If the Tsql is different between version 2000 and the later versions -- I would be grateful for both versions of the Tsql
--I noticed that multiple lines of Insert values doesn't work in Sql Server 2000 -- this sample is in Sql Server 2008
create table #tmp2(rowID int Identity(1,1), fk varchar(1), startDate datetime, endDate datetime)
insert into #tmp2
values
('a', '1/13/1985', '12/31/1999'),

It is unclear what you are trying to achieve, you said that it is SQL Server 2000 but provide a sample data with SQL Server 2008 syntax
Is it possible to use UNION ALL for your queries to make its one
select * from
select * from #tmp2 t1 where exists
(select * from (select top 1 * from #tmp2 t2 where t2.fk = t1.fk order by t2.startdate) x where x.rowID = t1.rowID)
UNION ALL
select * from #tmp2 t1 where exists
(select * from (select top 1 * from #tmp2 t2 where t2.fk = t1.fk order by t2.Enddate desc) x where x.rowID = t1.rowID)
as der order by fk

Performance Issue using min() and max() in one SQL statement

I have a simple query that selects min() and max() from one column in a table in one sql statment.
The table has about 9 Million rows and the selected column has a non unique index. The query takes 10 secs. When i select min() and max() in separate statements, each takes only 10 msecs:
This statement takes 10 secs:
select min(date_key) , max(date_key)
from CAPS_KPIC_BG_Fact_0_A
where date_key != TO_DATE(('1900-1-1' ),( 'YYYY-MM-DD'))
This statement takes 10 msecs:
select min(date_key)
from MYTABLE
where date_key != TO_DATE(('1900-1-1' ),( 'YYYY-MM-DD'))
union all
select max(date_key) from MYTABLE
Because the first statement is part of an autmatic generated SQL of an application, i can't change it and i have to optimize the data model. How can i speed up the first statement?

I've ran similar query on a table that has 10 milliion rows, with an index on the date column
This is what I have found:

Transactions between Min and Max dates

Hey all,
I have a requirement to extract data between min(transdate) and max(transdate), i got to do this using a single query, i used two queries, ie. 1 select for selecting the max and min dates and my second query to get the transactions. Can some one give me an idea to solve this, as Max & Min functions are not allowed in the where clause.
Thanks in Advance
- Eric

Why single fetch if you want effeciency then use analytic function
SQL> SELECT empno,ename,hiredate FROM
2 (SELECT empno,ename,hiredate,MAX(hiredate) OVER (ORDER BY empno) m,
3 MIN(hiredate) OVER (ORDER BY empno) mi FROM emp)

The syntax for the least function is:
least( expr1, expr2, ... )

SharePoint - Error_1_Error occurred in deployment step 'Add Solution': Timeout expired. The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool size was rea

Hi,
I am Shanmugavel, SharePoint developer,
I am facing the below SharePoint 2013 deployment issue while deploying using VS2012.
If i will deploy the same wsp or existing wsp
(last build) using direct powershell deployment, the solution adding properly, but the same timeout exception coming while activation the features. Please find the below error.
I tried the below activists:
1. Restarted my dev server, DB server.
2. tried the same solution id different server
3. tried existing wsp file (last build version)
4. Deactivated all the features, including project Active deployment configuration.... but still i am facing the same issue.
I hope this is not coding level issue, because still my code is not start running, before that some problem coming.
Please help me any one..... Last two days i am struck because of this...

What you need to understand is the installation of a WSP does not do much. It just makes sure that you relevant solution files are deployed to the SharePoint farm.
Next comes the point when you activate the features. It is when the code which you have written to "Activate" certain features for your custom solution.
Regarding the error you are getting, it typically means that you have more connections (default is I guess 100) open for a SQL database then you are allowed to.
If you have a custom database and you are opening a connection, make sure you close it as well.
Look at the similar discussion here:
The timeout period elapsed prior to obtaining a connection from the pool. This may have occurred because all pooled connections were in use and max pool
size was reached[^]
I would suggest further to look at the
ULS logs[^] to get better insight.

Min and max constraints

In my database design and implementation module I'm at the implementation stage. I've set up all of my tables with PK and FK constraints and I'm wondering if you can enforce min and max column constraints. One of the rules of my DB is for my staff table there has to be a minimum of 10 and a maximum of 50, how would I enforce this rule as a constraint on the staff table or isn't this possible?
We have only been learning database design and SQL fundamentals so I don't think I'd be allowed to use triggers or procedures.
Many thanks
Mike

Thing is my staff_id's are in the format 'S110001' will these constraints only check for integers 10 - 50? maybe I need to use a count function on the column or something?
thanks again for your help!
MikeCheck constraint can also be used to check a list of values.
example:
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name> LIKE <condition>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name> NOT LIKE <condition>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>
IN (<comma delimited list of values>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>
NOT IN (<comma delimited list of values>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name> BETWEEN <lower_value>
AND <higher_value>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>
NOT BETWEEN <lower_value> AND <higher_value>);
ALTER TABLE <table_name>
ADD CONSTRAINT <constraint_name>
CHECK (<column_name>) > (<condition>);

Parallel_max_server and max process

Hi,
is there any initial parameter like : max process ?
is there any relation between parallel_max_server and max process ?
I can not understand the last post of the followin thread :
Getting error in TNS connection from Oracle hosted on LINUX machine
I have the same TNS_12564 error.
Thanks.

Mines are :

Do I have to change them ?
I see nothing inherently wrong with them. Out of 150 processes, a maximum of 40 can be allocated to Parallel Slaves. It all depends how well you're managing/using parallel option on your workload.

Min and max functions

Hi,
I need to perform a calculation:
(max(min(C,2.375),0)+max(min(Y,2.375),0))/6
if the value of c is less than 2.375 then it has to accept the value of C else 2.375.
on it i need to perform the max operation.
How can i do this?

Hi,
MIN and MAX, like all the aggrgate functions, take only one argument.
Perhaps you're thinking of the row functions LEAST and GREATEST, which can take one or more arguments.
For example:
GREATEST ( LEAST ( c
                 , 2.375
         , 0
         )will return
2.375 if c is greater than 2.375,
0 if c is less than 0, or
c otherwise.
CAUTION: Unlike the aggregate functions, that ignore NULLs, GREATEST and LEAST will return NULL if any of their arguments are NULL.

MIN and MAX datetimes ti find range

I am using Oracle 11g version
create table re(Name char(20),Datetime char(45),val1 number);
insert into re values('abc','10/29/2012 13:00','1.5')
insert into re values('abc','10/29/2012 13:05','1.5')
insert into re values('abc','10/29/2012 13:10','1.5')
insert into re values('abc','10/29/2012 13:15','1.5')
insert into re values('abc','10/29/2012 13:20','0.00')
insert into re values('abc','10/29/2012 13:25','0.00')
insert into re values('abc','10/29/2012 13:30','0.00')
insert into re values('abc','10/29/2012 13:35','0.00')
insert into re values('abc','10/29/2012 13:40','2.1')
insert into re values('abc','10/29/2012 13:45','2.3')
insert into re values('abc','10/29/2012 13:50','2.1')
insert into re values('abc','10/29/2012 13:55','2.1')
insert into re values('abc','10/29/2012 14:00','2.2')
O/P:
In this way data is stored in database.Needed output is, I want the datetime column data range with min and max values where val1>0 only.
Expected result while we consider the above data is::
Name mintime maxtime
abc 10/19/2012 13:00 10/19/2012 13:15
abc 10/29/2012 13:40 10/29/2012 14:00
For this I tried something like this,
select name, min(to_date(Datetime ,'mm/dd/yyyy hh24:mi')) start, max(to_date(Datetime ,'mm/dd/yyyy hh24:mi')) end from (
select name, Datetime ,to_date(Datetime ,'mm/dd/yyyy hh24:mi') - rank() over (partition by loc_name order by t1 asc) Val_col from re where val1 > 0
) group by lname, Val_col
but I am getting the output like this for above query.
name start end
abc 10/29/2012 13:00 10/29/2012 13:00
abc 10/29/2012 13:05 10/29/2012 13:05

abc 10/29/2012 13:00 10/29/2012 13:00
abc 10/29/2012 13:05 10/29/2012 13:05
so.on.Firstly and most importantly do NOT store dates as char columns: that's what the DATE type is for.
Secondly, i'm not sure how you get your output from the input, particularly as your SQL contains 'partition by loc_name' which
doesn't even exist in your example table.
Why has the same name got two rows with those min/max times. Are you partitioning by val1?

Min and Max values from entire table

Hi,
i have requirement in which i need to find the min and max values from the entire table.
See the sample data
create table test
Sal1 int,
Sal2 int,
Sal3 int
insert into test values (100,700,5700)
insert into test values (200,3300,5300)
insert into test values (4400,1200,3500)
insert into test values (5400,5600,3100)
i want the output as 100 and 5700.. how can i achieve this in a single query. Please through some light on this topic..!
Thanking you in advance

Below is an example with a subquery for each of the queries Mohammad posted in order to return both min and max in a single result set.
SELECT ( SELECT MAX(Maxx) AS Maxx
FROM test UNPIVOT
( Maxx FOR E IN ( Sal1, Sal2, Sal3 ) ) AS unpvt
) AS Maxx
, ( SELECT MIN(Minn) Minn
FROM test UNPIVOT
( Minn FOR E IN ( Sal1, Sal2, Sal3 ) ) AS unpvt
) AS Minxx;

Distinct and max more than 2 column

Hi All,
Need help here. I have one table and need to display latest revision. But the problem is, i cannot use DISTINCT for column TITLE and MAX also failed when column is more than 2. I'm really stuck
I try below SQL statement but failed:
SELECT title, MAX(revision), coordinator
FROM specification
GROUP BY title, coordinator
But if my table have only 2 column, it's working:
SELECT title, MAX(revision)
FROM specification
GROUP BY title
Table Name: SPECIFICATION
TITLE          REVISION          COORDINATOR
SPEC-01          A                          John
SPEC-01          B                          Michelle
SPEC-01          C                          Andrew
SPEC-01          D                          John
SPEC-02          A                          Jenny
SPEC-02          B                          Robert
The result should be like below:
TITLE          REVISION          COORDINATOR
SPEC-01          D                          John
SPEC-02          B                          Robert

How to show Min and Max values when another value "changes to a new value"

Hi
If I have this data (generated with this query: SELECT 1 A, 1 B UNION ALL SELECT 2, 1 UNION ALL SELECT 3, 2 UNION ALL SELECT 4, 2 UNION ALL SELECT 5, 1)
A B
1 1
2 1
3 2
4 2
5 1
How can I generate this data (created with this query SELECT 1 Amin, 2 Amax, 1 B UNION ALL SELECT 3, 4, 2 UNION ALL SELECT 5, 5, 1)
Amin Amax B
1 2 1
3 4 2
5 5 1
Thanks.

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules. Temporal data should
use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
This is minimal polite behavior on SQL forums. You also do not know the ANSI/ISO syntax for insertion and you did the old Sybase insertion kludge wrong, that we need keys, etc.
CREATE TABLE Foobar
(foo_seq INTEGER NOT NULL PRIMARY KEY,
glop_score INTEGER NOT NULL);
INSERT INTO Foobar
VALUE
(1,1),
(2,1),
(3,2),
(4,2),
(5,1);
>> How can I generate this data (created with this query SELECT 1 Amin, 2 Amax, 1 B UNION ALL SELECT 3, 4, 2 UNION ALL SELECT 5, 5, 1) <<
This makes no sense; you have the wrong syntax and mixed data types. My guess is:
SELECT MIN(foo_seg), MAX(foo_seq), MAX(glop_score)
FROM Foobar
GROUP BY glop_score
HAVING MIN(glop_score) = MAX(glop_score);
Amin Amax B
1 2 1
3 4 2

Alert Queries and Max lines displayed

I have a query that I have set as an alert which triggers every monday morning. The query selects about 5000 rows from OITM but the alert only displays the first 90 or so. I also have SAP B1 set to email them to me but I get only the same 90 that show up in the alert window.
Is there any way to get the full 5000? I assume there is a max rows displayed setting somewhere and I am not seeing it.
Thanks.
[Edit]
I just read that the max alerts size in B1 is 64K. Is this correct? If so it might explain the problem. That being the case, how can I automatically email my self the results of the query? Should I go outside SAP and use some SQL process? (MS SQL '08)
Edited by: Erik S. on May 24, 2010 8:17 PM

Thanks for the reponses. I ended up doing an alert directly from SQL and cut out the middle-man.
I have to have 5000+ rows because I then give the file to my customers who incorporate my inventory on hand into their ecomm solutions. It is the only way that I have found to give exposure to inventory levels without creating a view for them in SQL.
