CtExcelData [datatable1]
DESIGNATION STATUS
------------------------------------------
ASSISTANT MANAGER - TRAINING ACTIVE
ASSISTANT MANAGER - TRAINING ACTIVE
ADMIN ASSISTANT ACTIVE
Designation [datatable2]
DESIG_ID DESIG_NAME
------------------------------------------
10 ASSISTANT MANAGER - TRAINING
20 ADMIN ASSISTANT
I want to replace datatable1 DESIGNATION text with designation id in datatable2 if designation name exactly matches between 2 datatables using lambda expression.
There will be multiple rows in 2 tables.
//CtExcelData datatable imported from excel compared with Designation datatable fetched from db. Updated excel datatable with id from db table matching the designationname
foreach (DataRow row in CtExcelData.Rows){
DataRow desigRowsToUpdate = DS.Tables["Designation"].AsEnumerable().FirstOrDefault(r => r.Field<string>("Desig_Name").ToUpper().Trim() == row.Field<string>("DESIGNATION").ToUpper().Trim());
if (desigRowsToUpdate != null)
{
row.SetField("DESIGNATION", desigRowsToUpdate.Field<decimal>("Desig_Id"));}
}

I'm relatively new to Oracle SQL and have run into an issue where I'm trying to filter a report to only return records logged by a specific list of user names.
They are currently stored in the system in fields user.first_name and user.surname and I've created the following CAST field in the coding to join the two together:
CAST(USER.FIRST_NAME||' '||USER.SURNAME as VARCHAR (25)) as CUSTOMER
What I want to do now though is restrict it so that my query will only return records where the customer is in a pre-determined list that I can hard core into the SQL.
eg I only want to see records for :
Joe Bloggs,
John Doe,
A Nother
How do I do this in Oracle SQL?
Thanks
One option (as you said you hardcoded it) is
select *
from your_table
where customer in ('Joe Bloggs', 'John Doe', 'A Nother');
A better one is to store those customers into a separate table and join it with your_table:
insert into separate_table (name) values ('Joe Bloggs'); -- do the same for the rest
select *
from your_table y join separate_table s on s.name = y.first_name ||' '||i.surname;
Even better, use their IDs (because, there could be two John Doe persons; which one will you take)?
insert into separate_table (id) values (1123); -- this is Joe Bloggs
select *
from your_table y join separate_table s on s.id = y.id;
This question has been posted several times but I am not able to get it work. I tried the approach mentioned in Update column to the COUNT of rows for specific values in another column. SQL Server. It gives me SQLException: java.sql.SQLException: ORA-01427: single-row subquery returns more than one row error not sure what I can do.
Below is my problem
UPDATE dataTable
SET ACCX = (select b.cnt
from dataTable a
join
(SELECT Account,
COUNT(1) cnt
FROM dataTable
GROUP BY Account) b
on a.Account=b.Account)
,ACCR = 15481
,ACCF = 3
WHERE ID = 1625
I only have the access & can change to the bold part since rest of the query is generated by the tool I cannot change it & I have to update ACCX column with the count of the value in column Account. Is it possible to do?
Note: - Account column is already populated with values.
You cannot follow that query because it is for sqlserver and NOT oracle. It is simpler in oracle and does not need a join to itself.
This update will set the count for id 1625 only based on number of account numbers in datatable. See demo here;
http://sqlfiddle.com/#!4/d154c/1
update dataTable a
set ACCR = 15481,
ACCF = 3,
a.ACCX = (
select COUNT(*)
from dataTable b
where b.Account=a.Account)
WHERE a.ID = 1625;
I have an Oracle APEX tabular form with the following columns:
Project,Rater Group,Ratee,Min Persons,Max Persons
Project and Rater Group are select lists. When I select a value for Rater Group I would like to limit the Rater Groups to only those Rater Groups in the Project in the first column. However the column attributes does not have a cascading value similar to form fields. Is there any way of doing this?
I've tried:
project_id = apex_application.g_f03(:APEX$ROW_NUM)
project_id = #PROJECT_ID#
project_id = :PROJECT_ID
project_id = apex_050000.wwv_flow_tabular_form.get_row_values
none of which works.
Found this page which links to some nice examples of how to cascade within tabular forms:
https://community.oracle.com/thread/2359498
The first link posted by 'Roel' shows a working example.
I have two oracle tables, table 1 contains students info and the second table contains student transaction details. Now I want an sql query to bring out the report of the transaction details for each student. eg student ID, name, amount, transaction date etc.
Note, a student can have many transactions, so I want a situation where by if student with ID 1 bought 3 items, in the result of the query I want to see student ID 1 and the sum of 3 items bought.
I don't want the student ID to repeat 3 times and the number of items bought.
Thanks
EDIT:
Here's the query I have so far:
select
distinct(s.spriden_id),
s.spriden_last_name,
s.spriden_first_name,
t.tbraccd_detail_code,
t.sum(tbraccd_amount),
t.tbraccd_term_code,
t.tbraccd_user,
t.TBRACCD_DATE
from SPRIDEN s, TBRACCD t
where s.spriden_pidm = t.tbraccd_pidm
and t.tbraccd_term_code = 201320
and t.tbraccd_desc = 'Misc Book Store Charges';
(The first table is SPRIDEN while the second table is TBRACCD)
You can use GROUP BY to group students, as below:
select
s.spriden_id,
sum(t.tbraccd_amount),
from SPRIDEN s, TBRACCD t
where s.spriden_pidm = t.tbraccd_pidm
and t.tbraccd_term_code = 201320
and t.tbraccd_desc = 'Misc Book Store Charges'
GROUP BY s.spriden_id;
MODIFIED VERSION to select all columns:
select
s.spriden_id,
t.tbraccd_entry_date,
t.tbraccd_term_code,
t.tbraccd_user,
sum(t.tbraccd_amount)
from SPRIDEN s, TBRACCD t
where s.spriden_pidm = t.tbraccd_pidm
and t.tbraccd_term_code = 201320
and t.tbraccd_desc = 'Misc Book Store Charges'
GROUP BY
s.spriden_id,
t.tbraccd_entry_date,
t.tbraccd_term_code,
t.tbraccd_user;
I am working in Asp.Net 4.0 C#-- MVC-3. I have one problem and don't know how to solve. I have 4 tables and want to fetch data from that tables with LINQ.
TABLES
1) Project_Master
Field Names :
project_id (pk)
project_name
company_id (FK with company_master)
company_category_id (FK with Company_Category_master)
project_status_id (FK with Project_Status_Master)
2)Company_Master
Field Names :
company_id
company_name
company_category_id (FK with Company_Category_Master)
3) Company_Category_Master
Field Names :
Company_Category_Id
Company_Category_Name
4) Project_Status_Master
Field Name :
Project_Status_Id
Project_Status_Name
Below are the fields I need to fetch..(using LINQ Query)
Company_Name
Total completed project using status id(1)=complete (where staus 1 means completed)
Total Project
Company_category_name
So, how can I fetch data with linq query??
Thanks in advance...
Try the below example:
(From lse In Me.Leases, nty In Me.Entities, psg In Me.ProductionStages, lsg In LeaseStages _
Where lse.LeaseName = leaseName _
Select lse, lsg, nty, psg).Single
or you can use below example too:
var employeesQuery = from populationTable in db.Populations
join personTable in db.Persons on populationTable.Guid equals personTable.PopulationGuid
join employeeTable in db.Employees on personTable.Guid equals employeeTable.PersonGuid
select new { populationTable, personTable, employeeTable};
