I have an application that uses Oracle Apex 4.2 . It has a form ( form and report on a table) that needs to display descriptions for columns on the table. For instance, there is a column on the table called fund which has a numeric value ( 1 to 6). There is a separate table that gives a description for each of these 6 values. Under EDIT PAGE ITEM, under SOURCE, I chose SOURCE TYPE -> SQL QUERY
I entered this query below:
SELECT DESCRIPTION FROM
"#OWNER#"."BU19ANT",
"#OWNER#"."FUNDCD"
WHERE ANTFUNDCD = CODE
where BU19ANT is the table that used for this form
FUNDCD is the name of the look up table
ANTFUNDCD and CODE and numeric fields on the respective tables and DESCRIPTION is the value that I want to look up and display on the form.
This gives me the correct answer MOST of the time, but not all the time.
The key to the table ( and the field used to link from the report to the form) is the Soc Security Number. If I run this same query against the Oracle table hard coding the SS Number, I always get the correct answer.
This form has 5 look ups that work this way and they all have the same problem.
I assume that I DONT need to include the Social Security Number as part of the query Apex already knows that.
But I tried to add that and can not figure out how to code it.
I tried
WHERE ANTSOCIALSECURITYNUMBER ( column on table) = P2_SOCIALSECURITYNUMBER ( the item on this page)
but that gave this error
ORA-00904: "P2_SOCIALSECURITYNUMBER ": invalid identifier
Is there some other way to code this? Or to say where SS Number = current record?
Or am I on the wrong track here?
Try :P2_SOCIALSECURITYNUMBER (for items on session) or &P2_SOCIALSECURITYNUMBER. (for items on page)

We have some data inside a table (Dimension) with historical values.
Like this (Small example)
ProductId is our Primary Key (and then is unique)
Code is our Business Key
Color and Type are our historical values
In Analysis Services (Tabular mode), our users want to build a report on that values.
Client usage Could be:
(1) If they only want to see the code ('CAR' in our example) the result would be:
(2) If they want to see the code and the Color:
Same for all the attributes that we can have and all the combinations.
Do you know how to solve this?
Can we add some logic in a calculated attribute
Thank you,

In essence, you want to aggregate by date? So, for any set of attributes you put in your pivot table, you want to show the earliest ValidFrom date and the latest ValidTo date that applies?
To accomplish this in SSAS Tabular, import the table and hide the columns ValidFrom & ValidTo. (To hide a column, right click it in Visual Studio and select Hide from Client Tools.)
Then, create 2 measures. For example:
Valid From := MIN([ValidFrom])
Valid To := MAX([ValidTo])
Note the extra space in the names to distinguish them from the column names. You could also call them something completely different. (E.g. Earliest Valid From Date)
When people connect to your cube, people will use these 2 measures rather than the columns from the original table. (They won't even see the columns because you've hidden them.)
If their pivot table includes all the attributes above (Product ID, Code, Color, Type), then the table will look exactly like your original table. If they only show Code, then your table will look like your (1). If they only show Code & Color, then your table will look like (2).
I have a table with 2 date fields and other columns. I have to be able to show stats on some of these columns between 2 dates that can be selected from a dropdown list.
All of this must be done in Apex. The client must be able to select a Start Date and an End date and then the count of for instance the number of Referrals between 01/SEP/17 and 30/SEP/17 must be shown.
The SQL code I used in Oracle to achieve this is:
select
'Total Referrals' as Details,
count(REFERRED) as Total
from PD_PATIENT_DETAILS where REFERRED = 'Yes'
and EVENT_DATE BETWEEN to_date(:EVENT_DATE) AND to_date(:EVENT_DATE_END);
I am now struggling to get this build in Apex. I only started working with Apex when I was brought onto this project. Have never worked with this before and am currently the only one working on it.
You can create 2 seperate page items and make them datepicker fields (P1_EVENT_DATE and P1_EVENT_DATE_END)
Your SQL query could look like this:
select
Total Referrals as Details
, count(REFERRED) as Total
from
PD_PATIENT_DETAILS
where
REFERRED = 'Yes'
and EVENT_DATE between :P1_EVENT_DATE and :P1_EVENT_DATE_END
Then you need to make an dynamic action (on change of one of the items, or make a go button) which submits the page or refreshes the report region (then you have to set the page items into the session state).
Something like this
In a recipe database I have two tables. One has the ingredients of every recipe [Recipe_ingr] and the other the available measures and weight for every ingredient [Weight2].
When I input a new ingredient for a recipe, I would like to be able to choose the available units for only that specific food.
I have tried with this expression in the control field but it prompts me to choose first, and then the options remain the same for all the records, not changing dinamically according to the record ingredient code.
SELECT [Weight2].[Msre_Desc], [Weight2].[Gm_Wgt] FROM Weight2 WHERE Weight2.NDB_No Like Recipe_Ingr.NDB_No ORDER BY [Msre_Desc], [Gm_Wgt];
Picture of my tables
Update:
I tried the syntax change suggested by June9 but still the control doesn't update automatically with every record as you can see in this picture: Table
Suggest you name controls different from fields they are bound to, like tbxNDB. The SQL needs to reference a field or control that is on the form. Also, LIKE operator without wildcard accomplishes nothing that an = sign wouldn't. Also recommend not using exactly same name for fields in multiple tables.
If you use that SQL statement in combobox RowSource, try:
SELECT Msre_Desc, Gm_Wgt FROM Weight2 WHERE NDB_No = [tbxNDB] ORDER BY Msre_Desc, Gm_Wgt;
You want to save Msre_Desc as foreign key, not a record id generated by autonumber?
Im building a system for my company to keep track of internal orders, inbetween our warehouses, we have material that goes out warehouse 1 to warehouse 2 and we kind of lose track of how much of "x" is in warehouse 1 and how much in warehouse 2, so i want to implement this access db where a user fills a form and says: order 1: 500 of "x" order 2: 300 of "y". then another user fills an exit form where he says 1 of "x" going out, so i would need the program to keep track of total order and how much as gone out to fill order 1 and so on...
My idea here is to have both an order number and an id number for each of "x" everytime someoneone assembles 1 "x" they fill the form and print a label directly from the access (i have this part working already) while keeping a record of when it was assembled, who verified and what was verified (it will work as a quality control also).
What i dont know is how to program the db so when it reaches 500 of "x", the id number for "x" starts again from 1
This is the one major issue with my program right now, i'm not experienced in access db's or vba, but im getting there with a tip and a trick from here and there, so, no need to be careful with the technical language, i will google it if i have to :p
EDIT:
The table structure goes as follows:
1 table as the main table where I record the check that is made for every product, where I include the model of the product, the said ID that I want to reset after a number of products checked, and a concatenated field that includes most of this information to generate a qr code.
Then there is a table for the Order Number, which is connected to a form to record each new order with a date/time field, the order number itself and the number of products. This number of products must then be called from the code that will count how many products have been checked to date and keep the order number field updated so we can keep track of the order.
Then there is another minor table just to get values for the form, the product models
Thank you for your answers ;)
See this MSDN Documentation
Unfortunately in Access, you cannot 'reset' an ID field, unless you move the records to a newly created table and use that table for every 500 records.
As for the user control and login form, I'm afraid those are separate questions that must be asked in a different thread.
To get you started:
You can set the RecordSource of a form to a table, and when users make entries, the data will be saved to the table. You can also use a form with controls (text boxes, comboboxes, etc.) and create a button that runs a query to insert these records into a table.
The login piece - you can encrypt the database with a password. That may/may not be sufficient.
I would suggest you change your schema, if possible. Something like the following:
Orders
OrderID (Autonumber)
ProductID (link to your Products table)
QuantityRequested
Deliverables
DeliverableID (Autonumber)
OrderID (link to your Orders table)
SequenceNumber: in the BeforeInsert event set this value equal to:
DCount("*", "Deliverables", "OrderID=" & Me.OrderID) + 1
I'm assuming that your form has a control named OrderID that is bound to the OrderID field of the Deliverables table.
The code uses the DCount() function to get the count of all the other deliverables that have already been created for this order. If this is the first deliverable, DCount() will return 0. It then adds 1 to this count to get the sequence number of the next deliverable.
If the new SequenceNumber is greater than the quantity requested, you could display a message saying that the order has been filled and cancel the creation of the Deliverable record.
This is just one approach and it is not a complete solution. I'm assuming that once assigned a sequence number a deliverable cannot be deleted. You might need to make allowances for deliverables that get lost or damaged. You could incorporate a status field to the Deliverable table to deal with this, but you would still need to make a decision about what to do with the SequenceNumber.
I'm developing an app which requires that the user selects a year formatted like this 1992-1993 from a spinner. The tablename is also named 1992-1993 and the idea is that using SQL the values from this table are pulled through with a statement like this select * from 1992-1993. When I run the emulator however, it throws an error.
If I then relabel the Spinner item to NinetyTwo and rename the table to NinetyTwo and run the emulator it runs as expected and the data is pulled through from the table.
Does SQLite have an issue with numbers in table names?
Yes and No. It has an issue with numbers at the beginning of a table name. 1992-1993 is an expression returning -1. Try to rename the table to Year1992.
Here a similar issue on SO.
sorry for late post
There may be a deeper issue here - is the structure you are using (table name per item in spinner) the best one for the job?
You may find that you want a number of tables e.g.
spinner_value (id, value)
form_data(id, spinner_value_id, etc ....)
