I am working with gridview and tables, I am using c# and asp.net. Assuming I have 2 tables, lets just name it Profiles and Info.
In table profiles let's say I have fields with p_Id, FirstName, LastName and in Transaction I have I_Id, childsID, fathersID, mothersID.
This is what my tables looks like:
Profile
| p_Id | FirstName | LastName |
| 1 | Jack | Cole |
| 2 | Cynthia | Cole |
| 3 | Robert | Cole |
Info
| I_Id | childsID | fathersID | mothersID |
| 1 | 1 | 3 | 2 |
Now in my gridview I have to display FirstName, LastName, Father and Mother. But I need to display their names not their ID's.
For now my gridview looks like this:
First Name | Last Name | Father| Mother |
Jack | Cole | 3 | 2 |
what I want is like this:
First Name | Last Name | Father | Mother |
Jack | Cole | Robert Cole | Cynthia Cole |
try this
select p.firstName, p.LastName
, (select sp.FirstName+' '+sp.Lastname FROM profile sp WHERE sp.p_id=i.fathersid) as father
, (select sp.FirstName+' '+sp.Lastname FROM profile sp WHERE sp.p_id=i.mothersid) as mother
from info i
inner join profile p ON (p.p_id=i.childsID)

I have the following cascade relationships between Parent and Child categories and keep the ChildCategoryId in the Personel table. When creating a new Personel record there are 2 cascade Dropdownlist and child records are listed according to their parents. Only ChildCategoryId is saved to the Personel table e.g. when select Education and Sales, the ChildCategoryId is 3. However, when selecting a parent record that has no child i.e. Family or Culture, I have no idea what value should be saved to the Personel table.
Of course I can add two "N/A" records to the Child table for Family or Culture records and save their Ids to the Personel table, but I am not sure if it is a good idea. Because when I list the Child category name, "N/A" will be displayed on the details page.
Is there a best practices for this kind of scenarios?
Personel:
Id | Name | ChildCategoryId |
----------------------------------
1001 | John | 1 |
1002 | Mary | 2 |
1003 | Bill | 3 |
1004 | Jose | 4 |
1005 | Anna | 5 |
ChildCategory:
Id | Name | ParentCategoryId |
-----------------------------------
1 | IT | 101 |
2 | Finance | 102 |
3 | Sales | 102 |
4 | PR | 103 |
5 | HR | 103 |
ParentCategory:
Id | Name |
------------------
101 | Health |
102 | Education |
103 | Sport |
104 | Family |
105 | Culture |
I have the following query to retrieve the customer sales report based on customer ID. It works, but how can I omit the customer name being duplicated?
select Cu.CustomerName, Cu.City, pd.pname,
Cs.qty, Cs.totalAmount, Cs.payed, Cs.credit, Cs.CreditEndDate
from Customer Cu
inner join CreditSales Cs on Cu.ID=Cs.CustomerID
left join Product pd on pd.pid=Cs.pid
where Cu.ID=6
order by Cu.CustomerName
The result is:
+--------+-------+---------------+----+----------+----------+----------+------------+
| Halima | Jimma | Mouse | 1 | 345.00 | 345.00 | 0.00 | 2015-08-29 |
| Halima | Jimma | Mobile | 10 | 92000.00 | 40000.00 | 52000.00 | 2015-08-23 |
| Halima | Jimma | Iphone | 2 | 13800.00 | 6500.00 | 7300.00 | 2015-08-28 |

+--------+-------+---------------+----+----------+----------+----------+------------+
But I need like this:
+--------+-------+---------------+----+----------+----------+----------+------------+

That means the customer name should displayed only one instance.
Any help? Thanks in Advance.
Based on Milen Pavlov response, you can try this:
SELECT CASE WHEN ROW_NUMBER() over (partition by [CustomerName] order by [CustomerName]) = 1 THEN [CustomerName] ELSE '' END
FROM Customer
ORDER BY [CustomerName]
This could do the job (I need you have to add an ordering in the over() clause):
select case when a.rn > 1 then '' else a.CustomerName end as CustomerName, a.City, a.pname, a.qty, a.totalAmount, a.payed, a.credit, a.CreditEndDate
from
(
select Cu.CustomerName, Cu.City, pd.pname,
Cs.qty, Cs.totalAmount, Cs.payed, Cs.credit, Cs.CreditEndDate, ROW_NUMBER() over (partition by Cu.CustomerName order by Cs.CreditEndDate) as rn
from Customer Cu
inner join CreditSales Cs on Cu.ID=Cs.CustomerID
left join Product pd on pd.pid=Cs.pid
where Cu.ID=6
) a
order by a.CustomerName
don't think it's a job for SQL but if you insists you can create two tables the first one with all the rows and columns and than delete the first row, and the other table with the first row and just make a left join and make the join on all the fields.
I have one confusion with SQL Query.
I have three tables, student, books, book_taken_by_student.
In the last table we have all the details about books taken by students.
In list view I bind the student name as row vies and different books name as column vies from student and books table.
The list view look like
| Book1 | Book2 | Book 3 | Book 4|
A |
B |
C |
D |
E |
F |
Now with help of book_taken_by_student table I want to bind Yes or No in front of student name related with book name taken by them
How I can solve this question.
Finally I want to show my list view like this
| Book1 | Book2 | Book 3 | Book 4|
A | Yes | No | Yes | Yes
B | No | Yes | Yes | No
C | No | Yes | Yes | No
D | Yes | No | Yes | Yes
E | Yes | No | Yes | Yes
F | No | Yes | Yes | Yes
I have multiple tables and made 2 sub-selects (UserRecord,CustomerRecord) that i would like to merge into 1 table
UserRecord
========================
| RecordID | UserName |
========================
| 1 | Sara |
| 1 | Tom |
| 2 | Sara |
| 2 | Kurt |
| 3 | Fre |
========================
Table: CustomerRecord
============================
| RecordID | CustomerName |
============================
| 1 | Jef |
| 2 | Alex |
| 2 | Peter |
============================
Table: This should be the result
=======================================
| RecordID | UserName | CustomerName |
=======================================
| 1 | Sara | - |
| 1 | Tom | - |
| 1 | - | Jef |
| 2 | Sara | - |
| 2 | Kurt | - |
| 2 | - | Alex |
| 2 | - | Peter |
| 3 | Fre | - |
=======================================
- = null
I tried with left, right, left outer, right outer ... join on the 2 tables but i don't get what i would like.
SELECT *
FROM UserRecord AS ur
INNER JOIN CustomerRecord AS cr ON ur.RecordID = cr.RecordID;
What you want is not a join, but a UNION:
SELECT RecordID, UserName, NULL AS CustomerName FROM UserRecord
UNION
SELECT RecordID, NULL AS UserName, CustomerName FROM CustomerRecord
... which just appends records from the two tables.
I'd just add that the order will not be the one you have shown in your expected result. If order is important then you should SELECT from this UNION and add an explicit ORDER BY clause on this outer select. Something like:
SELECT * FROM (
SELECT RecordID, UserName, NULL AS CustomerName FROM UserRecord
UNION
SELECT RecordID, NULL AS UserName, CustomerName FROM CustomerRecord
) ORDER BY RecordID, UserName, CustomerName
You can use a simple union
select recordid, username, null as customername from userrecord
union
select recordid, null, customername from customerrecord
I have to SP, from which i want to generate Report. I need output in two different Columns on one Detail Sections. I have tried Format with Multiple Columns, but it do not full fill my needs..
-- My Data
-- Student Record
+------+------------+
| Name | FatherName |
+------+------------+
| A | B |
| C | D |
| E | F |
+------+------------+
--Teacher Record
+------+------------+
|Name | FatherName |
+------+------------+
| W | X |
| Y | Z |
+------+------------+
My required out will look like below ...
Students Record Teachers Record
+------+------------+ +------+------------+
| Name | FatherName | | Name | FatherName |
+------+------------+ +------+------------+
| A | B | | W | X |
| C | D | | Y | Z |
| E | F | +------+------------+
+------+------------+
Is there any way to get this output in one Detail Section. Student and Teacher have different number of records, one have 10 record 2nd have 5 record..
Any Help...
You can't do this in one detail section in Crystal Reports.
However, you can develop a report for each of these tables separately, then add the two reports side-by-side as sub-reports into a new report - this should achieve your objective.
I think you can do it by right-clicking the details section then Insert->subreport, one for Teachers record and one for the Students record, then editing these subreports with their respective data source.
