How To Write A Sql Query to Show 0's

I never can remember this :-/ What do I have to do to get a SQL Query to return 0 if the Count of a condition is 0? For example lets say Joe, Jay, Jim could log on, but only Joe & Jim logged in Jay would not be returned in the query below. What
would I need to set-up so that All 3 users would be returned
Select logonName, Count(Logon)
From logonUserInfo
where logonName is not nullGROUP BY logonName

Currently there is only 1 table involved. I would need a separate table? What would this table need to hold?
You wouldn't need a separate table unless and until you want to store who logged in at what time and so on... then your table structures looks like below..
CREATE TABLE loginnames
loginid INT
name VARCHAR(30),
GO
CREATE TABLE loginTimes
loginid INT,
logintime DATETIME
GO
So, now you can do a left join on both tables on a certain date directly and find out who actually logined and who didn't with a count 0 for the one's who didn't login... and that will abide the principles of normalization as well...
If you don't want to use an another table, you would have to duplicate the loginnames everytime that user logins and also you don't have a track on what date the login happened.. So you will be considering from day 1 to Till date...
Please mark as answer, if this has helped you solve the issue.
Good Luck :) .. visit www.sqlsaga.com for more t-sql code snippets and BI related how to articles.

How to write a sql query to retrieve data entered in the past 2 weeks

Hi,
I have file names and last accessed date(java.sql.Date format) stored in my database table, I would like to know how I can write a query to get the name of files accessed in the past 2 weeks,I use open sql server at the back end.
Thanks in advance.

This has essentially nothing to do with JDBC. JDBC is just an API to execute the SQL language using Java and thus interact with the databases.
Your problem is related to the SQL language, you don't know how to write the SQL language. I suggest you to go through a SQL tutorial (there is one at w3schools.com) and to read the SQL documentation which come along with the database in question. A decent database manfacturer has a website and probably also a discussion forum / mailinglist as well.
I'll give you a hint: you can just use equality operators in SQL like everywhere. For example: "WHERE date < somedate".

How to write this SQL query

We have a table, the structure as below: (I put a blank row in the middle to make it clear)
Product_ID     Retailer     Retail_Price
1001          A          1.2
1001          B          1.5
1001          C          1.4
1002          B          2.0
1002          C          2.1
1002          E          1.8
1002          F          2.0
1003          A          1.7
1003          C          1.5
Basically we use the table to compare the retail price for different retailers in terms of different products. My customer asked me to give a report based on above table but only shows the retail prices which contain retailer A.
For example, on above table I need to give a report like below:
Product_ID     Retailer     Retail_Price
1001          A          1.2
1001          B          1.5
1001          C          1.4
1003          A          1.7
1003          C          1.5
Can anybody give some ideas on how I should write a SQL to achieve this.
Many thanks!

Hi,
Can anyone help me to find out if there is a approach to build a SQL Query without using group by clause.
Please site an example if is it so,

I hope this example could illuminate danepc on is problem.
CREATE or replace TYPE MY_ARRAY AS TABLE OF INTEGER
CREATE OR REPLACE FUNCTION GET_ARR return my_array

     arr my_array;
begin
     arr := my_array();
     for i in 1..10 loop

end;
select column_value
from table(get_arr)
order by column_value;
select column_value,count(*) occurences
from table(get_arr)
group by column_value
order by column_value;And the output should be something like this:

Hi sir,
i am using one query in my sql stored procedure that is:

so here i am getting this value 01/01/1900 12:00 AM
the same i used in oracle my query is :
to_char(Out_Time,'1900-01-01' + 0/(24*60),'DD/MM/YYYY HH:MI AM')

FROM shift
WHERE Shift_Code = v_ShiftCode;
but getting error that is: Encountered the symbol INTO when expecting one of the following :=(%;
am i doing any thing wrong.

It would be easier if you expalined what business logic you're trying to implement instead of asking us to interpret a piece of shonky SQL.It's yet another of the OP's questions about how to do DATEs in Oracle (so many threads it can get very confusing - even though the OP has been asked to stick to one thread!).
The code looks like it's based on the answer I gave here:

How to write an SQL query

Hi,
My table is similar to the below table. In the below table each case has one or more hometowns. But I need only one hometown for each case for that it has to select most recently (column date_mod)date if a case has two same (column date_mod) then it has to take maximum (column number)
For example in the below case for Case A it has same date_mod columns then it has to take maximum number which is 4. So the hometown for case A is Fairfiled so I have to select this hometown and I should ignore remaining hometowns. How to do this?

How to write the SQL query for generating triangular numbers

Hi,
I have a table ..which stores the sequence number like this
Seq :
1000
1200
1300
1500
1800
1900
Now i want to get a result like this
1000 1000
1200 2200
1300 3500
1500 5000
1800 6800
1900 8700
how can it be achieved. I tried using Lead and lag. but only I can add the n+1 or n-1 results. Please help.

I've never heard it called 'triangular numbers' before but I think you're looking for a 'running total':
SQL> WITH data AS
2 (
3     SELECT 1000 AS num FROM dual UNION ALL
4     SELECT 1200 AS num FROM dual UNION ALL
5     SELECT 1300 AS num FROM dual UNION ALL
6     SELECT 1500 AS num FROM dual UNION ALL
7     SELECT 1800 AS num FROM dual UNION ALL
8     SELECT 1900 AS num FROM dual
9 )
10 /* END SAMPLE DATA */
11 SELECT num, SUM(num) OVER (ORDER BY num) AS running_total
12 FROM   data
13 ORDER BY 1
14 ;
       NUM RUNNING_TOTAL
      1000          1000
      1200          2200

Debra,
Sorry but you have posted to a forum that deals exclusively with questions/issues about customizing and programming Microsoft Project, a planning and scheduling application. I suggest you delete this post and find a more appropriate forum.

How to view the sql query?

hi,
how to view the sql query formed from the xml structure in the receiver jdbc?

You can view SAP Note at
http://service.sap.com/notes
But you require SMP login ID for this which you should get from your company. The content of the notes are as follows:
Reason and Prerequisites
You are looking for additional parameter settings. There are two possible reasons why a feature is available via the "additional parameters" table in the "advanced mode" section of the configuration, but not as documented parameter in the configuration UI itself:
Category 1: The parameter has been introduced for a patch or a SP upgrade where no UI upgrade and/or documentation upgrade was possible. In this case, the parameter will be moved to the UI and the documentation as soon as possible. The parameter in the "additional parameters" table will be deprecated after this move, but still be working. The parameter belongs to the supported adapter functionality and can be used in all, also productive, scenarios.
Category 2. The parameter has been introduced for testing purposes, proof-of-concept scenarios, as workaround or as pre-released functionality. In this case, the parameter may or may not be moved to the UI and documentation, and the functionality may be changed, replaced or removed. For this parameter category there is no guaranteed support and usage in productive scenarios is not supported.
When you want to use a parameter documented here, please be aware to which category it belongs!
Solution
The following list shows all available parameters of category 1 or 2. Please note:
Parameter names are always case-sensitive! Parameter values may be case-sensitive, this is documented for each parameter.
Parameter names and values as documented below must be used always without quotaton marks ("), if not explicitly stated otherwise.
The default value of a parameter is always chosen that it does not change the standard functionality
JDBC Receiver Adapter Parameters
1. Parameter name: "logSQLStatement"
              Parameter type: boolean
              Parameter value: true for any string value, false only for empty string
              Parameter value default: false (empty String)
              Available with: SP9
              Category: 2
              Description:
              When implementing a scenario with the JDBC receiver adapter, it may be helpful to see which SQL statement is generated by the JDBC adapter from the XI message content for error analysis. Before SP9, this can only be found in the trace of the JDBC adapter if trace level DEBUG is activated. With SP9, the generated SQL statement will be shown in the details page (audit protocol) of the message monitor for each message directly.
              This should be used only during the test phase and not in productive scenarios.

Prateek
