Transact SQL :: Retrieve All Records From Parent Table And Any Records From Child Table

Oct 21, 2015

I am trying to write a query that will retrieve all students of a particular class and also any rows in HomeworkLogLine if they exist (but return null if there is no row). I thought this should be a relatively simple LEFT join but I've tried every possible combination of joins but it's not working.

SELECT
Student.StudentSurname + ', ' + Student.StudentForename AS Fullname,
HomeworkLogLine.HomeworkLogLineTimestamp,
HomeworkLog.HomeworkLogDescription,
ROW_NUMBER() OVER (PARTITION BY HomeworkLogLine.HomeworkLogLineStudentID ORDER BY

[Code] ...

It's only returning two rows (the students where they have a row in the HomeworkLogLine table).

Cannot Retrieve All The Records In A Recordset

Mar 31, 2008

I am using ADODB.Recordset to retrieve the records from an MS Access database. The table has 11450 records and the recordset shows this number as the recordcount too. But when I try to fetch the records in a While loop using EOF as the check, I am able fetch only 4000 or so records. No error occurs and no exception is thrown. Control just comes out of the function. Why could this be happening?
Does Recordset have some limit on the number of records for Jet 4.0 provider?

Any help is appreciated.

Query To Retrieve Records That Sum To A Field In Another Table

May 18, 2012

I really need creating a query that will retreive all records from a table where the dbo.CorpAdv.AcctNum field equals a specific value (for this example "0023"), the TranCode = "R" and the sum of the records, starting with the latest, equals the value of a field in another table (dbo.Master.TotalAdv)

dbo.CorpAdv.pID is an integer and unique ID for each record, later records have higher numbers
dbo.CorpAdv.AcctNum is text field
dbo.CorpAdv.AdvAmt is numeric (dollar amounts)

How To: Retrieve A Limited Number Of Records From A Record Set

Apr 24, 2008

I€™m working on a database project that will ultimately contain millions of records for each lot. In addition, each lot will have up to 96 corresponding serial number records.

I would like to add a SQL parameter that would tell the database engine to only return X number of records.

For Example:
If table TBL_LOTS contains one million records I would like to limit the return set to 100 for example.

What would I need to add to the SQL command to below to restrict the data set to the first 100 records in the set of one million?

Trouble Writing Stored Procedure To Retrieve Records By Selected Month And Year

May 15, 2007

hi,
i am a nubie, and struggling with the where clause in my stored procedure. here is what i need to do:
i have a gridview that displays records of monthly view of data. i want the user to be able to page through any selected month to view its corresponding data. the way i wanted to do this was to set up three link buttons above my gridview:
[<<Prev]  [Selected Month]  [Next>>]
 the text for 'selected month' would change to correspond to which month of data was currently being displayed in the gridview (and default to the current month when the application first loads).  
i am having trouble writing the 'where' clause in my stored procedure to retrieve the selected month and year.
i am using sql server 2000. i read this article (http://forums.asp.net/thread/1538777.aspx), but was not able to adapt it to what i am doing.
i am open to other suggestions of how to do this if you know of a cleaner or more efficient way. thanks!

--- Structure of the target table
create table trg
(
cyear int,
district varchar(10),
school varchar(10),
RollNo int,
zipcode varchar(10),
type varchar(20), /* This is an extra column with hard coded values which we need to assume as Total,flag1_handicapped,flag2_Disadvantaged.For Every unique zipcode i need to GROUP BY these 3 values.

empl_related int,
empl_not_related int,
modified_date datetime
)

-- The below table shows what values should get loaded into trg table

type /* here we to load 3 rows with 3 values
This table contains some calculated columns. such as "actual_cnt","empl_related","empl_not_related" and so on...
Every calculation should be grouped by this "type" column.For reference the you can see the bottom output rows how they should look like.
The 3 valid values for this type column is "Total","flag1_handicapped","Disadavantaged".
"Total" means = All the records which satisfies the calculation.
"flag1_handicapped" means = All the records which statisfies the calculation and have test.flag1_handicapped = 'Y'
"flag2_Disadvantaged" means = All the records which satisfies the calculation and have test.disadvanatged = 'Y'*/


actaul_cnt This is a calculated column. The calc is as follows:
count of records grouped by currentyear,district,school,zipcode,type(flag1_han dicapped,flag2_Disadvantaged,total)

empl_relatedThis is again calculated column. The calc is as follows.
count of records where status='E' and relation = 'R' grouped by currentyear,district,school,zipcode,type(flag1_han dicapped,flag2_Disadvantaged,total)

empl_not_related This is again calculated column. The calc is as follows.
count of records where status='E' and relation = 'NR' grouped by currentyear,district,school,zipcode,type(flag1_han dicapped,flag2_Disadvantaged,total)


modified_date getdate()

-----------------------------------------------------------------------------------------------


Here is the sample template which i felt like using to load the data. We need to modify this query littlt bit accordingly as per above rules.

select
currentyear as "CYear",
district as "District",
school as "School",
rollno as "RollNo",
zipcode as "zipcode",
count(*) "actaul_count",
sum(case when (status='E' and relation='R') then 1 else 0 end) "Emp_Related",
sum(case when (status='E' and relation='NR') then 1 else 0 end) "Emp_Not_Related",
getdate() "Date"
from test
group by currentyear,
district,
school,
rollno,
zipcode

/* Using the above query we need to load 3 rows into below target table whose structure is defined as follows */



------------------------------------------------------------------------------------------------------------------------

Expected Output Rows using above sample data
----------------------------------------------------
CYEAR|DISTRICT|SCHOOL|ROLLNO|ZIPCDE| TYPE |ACTUALCOUNT| EMPL_RELATED |EMPL_NOT_RELATED |MODIFIED_DT
-------------------------------------------------------------------------------------------------------------------------
2005 | D1 | S1 | 101 | 530024 | Total | 11 | 2 | 9 | 2002-01-26
2005 | D1 | S1 | 101 | 530024 | flag1_handicapped | 2 | 1 | 1 | 2002-01-26
2005 | D1 | S1 | 101 | 530024 | flag2_Disadvantaged | 2 | 1 | 1 | 2002-01-26



------------------------------------------------------------------------------------------------------------------------
But using above SELECT,i am able to get only row as output that to i am not able to show the "type" column in the output

2005 | D1 | S1 | 101 | 530024 | 11 | 2 | 1 | 2002-01-26 12:57:53.420 |


------------------------------------------------------------------------------------------------------------------------
Basically i am not getting how to build the Group by clause and displaying the type code using above rules.
Can anyone help me out in solving the problem.
Do we need to perform any UNION ALL ON test.flag1_handicapped and test.flag2_Disadvantaged columns.?
This is totally seems out of box for me.

Any help would be greatly appreciated.


Thanks in Advance.

Any College Students In The House?

Nov 19, 2006

Hello!

My name is Dr. James Triton. I am working on a research program for an unnamed University. Without getting into too much detail, I was wondering if any lower level college (or perhaps late high-school, depending on the strength of your Computer Science program) would be interested in filling out a few SQL queries, making an ER model or DDLs for a database.

Here is some example questions:

1.List each employee's first name, middle initial, and last name, concatenated to form a single value, as well as how many years they have been working for the company. An example name would appear as "JOHN Q SMITH". Sort the output by descending number of employment years. (HINT: create a column alias.)
2.List all of the job functions (such as "CLERK"), and the last names of all employees associated with each function. Order the output alphabetically by the functions. (HINT: there are a total of seven different functions.)
3.List the last name of every manager, along with the last names of the employees that the manager manages. Create column aliases "MANAGER" and "EMPLOYEE", and order the output by manager last name.

(there are 15 such queries)
The table for these is located here:

Please email me if you are interested!

I create a function called UpdatePasswordByUserId in my dataset with the above stored procedure that returns a scalar value. When I preview the data from the table adapter in my dataset, it spits out the right value.

Retrieve Text File Data In SSE For Data Acquisition System

Oct 24, 2007

Hey All,
I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel. I am trying to use SSE to retrieve the data from the text file, and parse each line of data into individual columns in a databse. Then I want to be able to extract the data associated with a particular ATD channel number from the databse and display it in the appropriate text field on a windows form.
I've got the MCU programmed. I have no problem collecting the data from the serial port, and I can do the visual basic programming okay. I have absolutely no clue how to read the data into the database, continuosly read new values into the databse, and then access the stored data to update the text fields on the form. Please help if you can, I've been working on this specific problem for a couple of weeks and I'm not making any progress. Thanks.

Transact SQL :: Trigger Execution With OLEDB Connection From In-house Application

Oct 28, 2015

issues with triggers in Sql Server 2014.

A few weeks ago I've done a SQL Server migration from SQL Server 2000 to SQL Server 2014.It was a bit tricky but anything worked fine.

I have some legacy VB6 (Visual Basic 6) applications written in house which worked with Databases on the old SQL server 2000.Surprisingly, these applications worked well after the upgrade to SQL Server 2014 without having to change a piece of code.

Now, some users tell me that they receive some unusual message when saving data  from these legacy applications.After investing for a few hours, I discovered that triggers are not executed when those users try to save data from grids or forms in their applications.Trying to reproduce the INSERT statement in SQL Server Management Studio, the triggers run well.From the application, they don't.

These applications connect to Database Server thru OLEDB connection with the following ADO connection string :

Provider=SQLOLEDB.1;Password={password};User ID={user};Initial Catalog={db};Data Source={datasource}.the {user} is a true SQL account who have read/write/delete access in the databases.

On the web there is a lot of questions involving the same issue, but only from SSIS.I found some articles about an OLEDB connection parameter named FastLoadOptions with a value of FIRE_TRIGGERS, but nowhere how to put it in the ADO OLEDB connection string.

how to reactivate the "normal" use of triggers from an ADO OLEDB connection ?Either with some obscur parameter in the connection string or options somewhere in the SQL Server 2014.

Retrieve Text File Data In SSE For Data Acquisitio

Oct 24, 2007

Hey All,
I am developing a data acquistion system which monitors the amount of energy that a user consumes in different parts of a house and displays the information in real time on their computer screen. I am collecting the data through tranducers attached to the circuit breakers in the breaker box and sending the data to analog-to-digital converter channels in a MCU. I am retrieving the data from the serial port and storing it to a text file. Each line of data in the text file represents three fields which are separated by commas. I will be reading data from multiple data collection boxes so the first field is the unit number, the second fied represents the analog-to-digital converter channel number from each unit, and the third field is the data that is collected from the ATD channel.

What's The Accepted Way To Retrieve Records In A SQL Table With Null Values Using A Visual Studio 2005 Table Adapter?

Jan 21, 2008

I'm using an ObjectDataSource in Visual Studio to retrieve records from a SQL Server 2005 database.
 I have a very simple dilemma.  In a table I have fields FirstName, Surname, Address1, Address2, Address3 etc. None of these are mandatory fields.
It is quite common for the user not to enter data in Address2, Address3, so the values are <null> in the SQL table.
In Visual Studio 2005 I have an aspx form where users can pass search parameters to the ObjectDataSource and the results are returned according to the passed in parameters.
The WHERE clause in my Table Adapter is:WHERE (Address1 LIKE @Address1 + '%') AND (Address2 LIKE @Address2 + '%') AND   (Address3 LIKE @Address3 + '%') AND (FirstName LIKE @FirstName + '%') AND (Surname LIKE @Surname + '%')
If, for example, I simply want to search WHERE FirstName LIKE ‘R’, this does not return any results if the value of Address3 is <null>
My query is this: Could someone please show me the best way in Visual Studio 2005 to return records even if one of the Address fields is <null>.
For reference, I have tried: Address3 LIKE @Address3 + '%' OR IS NULLThis does work, however itsimply returns every instance where Address3 is <null>  (accounting for about 95% of the records in the database). Thanks in advance Simon
