I create a new function modul in abap which should return a list of the data element AGVAL.
AFAIK there are two ways now:
I use an already available table type
I create a new table type
How to do this kind of introspection? I would like to now if there is already a table type with one column, which is of type AGVAL?
you can enter your element type in TA SE11 as Data Type.
Go to display and use the Where-Used-List to search for table fields / strucure fields to find the usage of this data element.

I don't know any option else but using SQL to query the ABAP dictionary directly.
For instance, this query extracts all table types having a structure whose first component has the data element SO_TEXT255 (and which is not embedded in a nested structure) :
SELECT * FROM DD40L
WHERE ROWKIND = 'S'
and ROWTYPE in (
select TABNAME from DD03L
where POSITION = 1
and ROLLNAME = 'SO_TEXT255' )
Of course, it doesn't restrict to structures with only this one component but you may adapt it a little bit.
If you do not stick purely to ABAP-way it is done via SE11 in a very simple way.
Search by table types
Choose search type as "by reference line"
That's it!

We have a legacy vb6 solution working with an access database with one of the forms containing a number of mutually exclusive option buttons
There is no reference table and the options are saved/loaded using hard coding ie. values in the field optState would be either 0, 1 or 2.
We are building a query in Access to export data into XML and looking for a way to convert the options into text fields without updating the DB or VB application!. So if 0 show some text, 1 some other text ... etc.
Is there a way we can do this in the access query or access sql?
No plans to upgrade the VB or DB so looking for a workaround.
thanks

You could use IIf (Immediate If) to do this in a query. As you have multiple values per field, you would need to nest them. Something like:
SELECT tblStatus.*,
IIf([Status]=0,"Available",IIf([Status]=1,"Sold",IIf([Status]=2,"Withdrawn",""))) AS StatusOut
FROM tblStatus;
This returns an empty string if a value is not 0/1/2. Or you could use Switch in the query:
SELECT tblStatus.*,
Switch([Status]=0,"Available",[Status]=1,"Sold",[Status]=2,"Withdrawn") AS StatusOut
FROM tblStatus;

I have a database. I created it with HeidiSQL. Its look like this.
I enter the value-1 and value-2.
Is there a way to enter a formula to Result column like " =Value-1 * Value-2 " ? I want my database to calculate the Result when I enter my values to other cells.
A trigger is one way to achieve automated column content.
A second one is a view, which you can create additionally to the table. That view could contain SQL which generates the result:
SELECT value1, value2, value1*value2 AS result
A third (more modern) alternative is adding a virtual column in your existing table. You can do that with HeidiSQL's table editor, like shown in the screenshot. Just add a new column with INT data type, and set its Virtuality to "VIRTUAL", and Expression to "value-1 * value-2". That's it.
I'm not familiar with HeidiSQL, but it appears to be a front end? What RDBMS are you using, for example SQL Server allows a computed column.
SQL
ALTER TABLE YourTable
ADD Result AS ([Value-1] * [Value-2])
Right click your database name in the folder structure, go to --> create new then -->Trigger
Then you can create a trigger that when entering data, will be activated on the entire column like this:
But you will need to know how to write the actual query and function. This requires basic knowledge that is generally generic and consistent of most all SQL languages.
I have list of 100 views for which I need to check if those views have fields A and B. If any of those 100 views uses those two fields, I need to display a message. Any existing function module will help.
Sujeet,
Function module ISB_TABLE_READ_FIELDS accepts a table or view name and returns a table of fields on the structure. If you don't have this function module, you can write your code to select entries from table DD03L, which is keyed on table name and contains all of the fields on all database table structures.
Once you have the list of fields, the code to implement the logic you want should be trivial.
I doubt there is an existing SAP Function Module to do this - I suspect you will have to write some ABAP or do some Excel manipulation.
I would expect that there is a table within SAP which defines views - I'm not sure which though.
If no-one suggests anything else I would use ST05 - "SQL Trace" to see which tables SAP reads when you call SE12 to look at the view you are interested in. You can look at the SELECT statements and see which tables it reads to get the view definition.
I just tried pressing F1 on a field in SE12 for a view to see if there was a mention of a table. The technical info made reference to a structure containing the string "DD27" - I had a look in SE16 for tables with similar names and DD27SV looks like it might help.
Have a look and see what you think - you'd need to query that table in some ABAP or extract to Excel and do equivalent manipulation there.
I have the following problem:
I'm testing many BAPI's and dont want to create a Table with the corosponding types for the rows, each time I call a new BAPI.
Is it possible to generate s.th. like a generic table like:
DATA foo TYPE ANY TABLE.
and use this to put it as the table parameter to get the result of the bapi?
No, this is not possible - you can't declare variables using a generic type. However, you could try to determine the data type (e. g. using RPY_FUNCTIONMODULE_*) and then use CREATE DATA to create the table dynamically using a reference. Check the documentation of CREATE DATA for an example.
Hi I have a table which was designed by a lazy developer who did not created it in 3rd normal form. He saved the arrays in the table instead of using MM relation . And the application is running so I can not change the database schema.
I need to query the table like this:
SELECT * FROM myTable
WHERE usergroup = 20
where usergroup field contains data like this : 17,19,20 or it could be also only 20 or only 19.
I could search with like:
SELECT * FROM myTable
WHERE usergroup LIKE 20
but in this case it would match also for field which contain 200 e.g.
Anybody any idea?
thanx
Fix the bad database design.
A short-term fix is to add a related table for the correct structure. Add a trigger to parse the info in the old field to the related table on insert and update. Then write a script to [parse out existing data. Now you can porperly query but you haven't broken any of the old code. THen you can search for the old code and fix. Once you have done that then just change how code is inserted or udated inthe orginal table to add the new table and drop the old column.
Write a table-valued user-defined function (UDF in SQL Server, I am sure it will have a different name in other RDBMS) to parse the values of the column containing the list which is stored as a string. For each item in the comma-delimited list, your function should return a row in the table result. When you are using a query like this, query against the results returned from the UDF.
Write a function to convert a comma delimited list to a table. Should be pretty simple. Then you can use IN().
