Items and SQL Types

I've just started learning apex and I'm confused about page/application items. Since they can be used in SQL and PL/SQL as some kind of variables (for example using bind variable syntax), at some point they should be prescribed a type, since SQL and PL/SQL are both strongly typed languages.
It seems that items do have types, see the documentation (http://docs.oracle.com/cd/E11882_01/appdev.112/e11947/bldapp.htm#BCEDCGGH), but I'm not sure how they correspond to SQL types.
For example I saw that to_date is always used with items of date picker type, implying it is some string SQL type.
So the question. What SQL type do apex page/application items have, that is what type conversion do I need to use when dealing with items inside SQL and PL/SQL?

They are all VARCHAR2(4000) as far as I know - all application item are the same and the page items can be set to number or date in addition. Setting it to number or date will only include an internal validation checking if the format is matching the application globalization settings.

Debit/Credit sign settings of item and movement type usage

Dear BCS Experts,
According to your experience, where are Debit/Credit sign settings of item and movement type used in BCS? As I know, they can be used during data collection. Any other thoughts?
Thanks.

Actually, Barry, I recognised that that was not a doubt regarding BCF. It was (and still is) a doubt about the MoveType sign for that values that are generated automatically during the CoI activities.
Since the decrease/increase for such activies is defined, there is a question if the sign of these MoveTypes may interfere with the amounts or the side to be placed in (debit or credit).
Do you have experience in this?

Records and Objects, Cast for PL/SQL Type RECORD and SQL Type OBJECT

Hi seniors:
In my job, we have Oracle 10g, programming with Packages, the parameters are PL/SQL Types,
Example:
PACKAGE BODY NP_CONTROL_EQUIPMENT_PKG
IS
TYPE TR_EQUIPMENT_OPERATION IS RECORD(
wn_npequipmentoperid CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.npequipmentoperid%TYPE,
wv_npactiveservicenumber CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.npactiveservicenumber%TYPE,
wv_npspecification ORDERS.NP_SPECIFICATION.npspecification%TYPE,
wv_nptype ORDERS.NP_SPECIFICATION.nptype%TYPE,
wn_nporderid CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.nporderid%TYPE,
wn_npguidenumber CONTROL_EQUIPMENT.NP_EQUIPMENT_OPERATIONS.npguidenumber%TYPE,
wd_npdevolutionprogramdate CONTROL_EQUIPMENT.NP_EQUIPMENT_STATUS.npdevolutionprogramdate%TYPE
TYPE TT_TR_EQUIPMENT_OPERATION_LST IS TABLE OF TR_EQUIPMENT_OPERATION INDEX BY BINARY_INTEGER;
PROCEDURE SP_GET_EQUIPMENT_OPERATION_LST(
an_npequipstatid IN CONTROL_EQUIPMENT.NP_EQUIPMENT_STATUS.npequipstatid%TYPE,
at_equipment_operation_list OUT TT_TR_EQUIPMENT_OPERATION_LST,
av_message OUT VARCHAR2
IS
BEGIN
SELECT EO.npequipmentoperid,
EO.npactiveservicenumber,
S.npspecification,
S.nptype,
EO.nporderid,
EO.npguidenumber,
ES.npdevolutionprogramdate
BULK COLLECT INTO at_equipment_operation_list
FROM NP_EQUIPMENT_OPERATIONS EO,
NP_EQUIPMENT_STATUS ES,
ORDERS.NP_ORDER O,
ORDERS.NP_SPECIFICATION S
WHERE EO.npequipstatid = ES.npequipstatid
AND EO.nporderid = O.nporderid
AND O.npspecificationid = S.npspecificationid
AND EO.npequipstatid = an_npequipstatid;
EXCEPTION
WHEN OTHERS THEN
av_message := 'NP_CONTROL_EQUIPMENT_PKG.SP_GET_EQUIPMENT_OPERATION_LST: '||SQLERRM;
END SP_GET_EQUIPMENT_OPERATION_LST;
END;
Procedures calls other procedures and passing parameters IN OUT defined that PL/SQL Types. The problem appears when the access is through Java. Java can't read PL/SQL Types because only read SQL Types (Types defined in SCHEMA):
CREATE OR REPLACE
TYPE TO_EQUIPMENT_OPERATION AS OBJECT (
wn_npequipmentoperid NUMBER,
wv_npactiveservicenumber VARCHAR2(15),
wv_npspecification VARCHAR2(8),
wv_nptype VARCHAR2(2),
wn_nporderid NUMBER,
wn_npguidenumber NUMBER,
wd_npdevolutionprogramdate DATE
CREATE OR REPLACE
TYPE TT_EQUIPMENT_OPERATION_LST
AS TABLE OF "CONTROL_EQUIPMENT"."TO_EQUIPMENT_OPERATION"
Java can read this SQL Types. The problem is how cast OBJECT to RECORD, because I can't execute that:
DECLARE
wt_operation_lst TT_EQUIPMENT_OPERATION_LST;
BEGIN
SELECT EO.npequipmentoperid,
EO.npactiveservicenumber,
S.npspecification,
S.nptype,
EO.nporderid,
EO.npguidenumber,
ES.npdevolutionprogramdate
BULK COLLECT INTO wt_operation_lst
FROM NP_EQUIPMENT_OPERATIONS EO,
NP_EQUIPMENT_STATUS ES,
ORDERS.NP_ORDER O,
ORDERS.NP_SPECIFICATION S
WHERE EO.npequipstatid = ES.npequipstatid
AND EO.nporderid = O.nporderid
AND O.npspecificationid = S.npspecificationid
AND EO.npequipstatid = an_npequipstatid;
END;
and throws NOT ENOUGH VALUES, and I modified to:
DECLARE
wt_operation_lst TT_EQUIPMENT_OPERATION_LST;
BEGIN
SELECT TO_EQUIPMENT_OPERATION(EO.npequipmentoperid,
EO.npactiveservicenumber,
S.npspecification,
S.nptype,
EO.nporderid,
EO.npguidenumber,
ES.npdevolutionprogramdate)
BULK COLLECT INTO wt_operation_lst
FROM NP_EQUIPMENT_OPERATIONS EO,
NP_EQUIPMENT_STATUS ES,
ORDERS.NP_ORDER O,
ORDERS.NP_SPECIFICATION S
WHERE EO.npequipstatid = ES.npequipstatid
AND EO.nporderid = O.nporderid
AND O.npspecificationid = S.npspecificationid
AND EO.npequipstatid = an_npequipstatid;
END;
Worst is that I can't modify this procedure and PL/SQL Types will survive.
I have create a copy that CAST RECORD to OBJECT and OBJECT to RECORD too.
PROCEDURE SP_COPY_PLSQL_TO_SQL(
an_npequipstatid IN NUMBER,
at_dominio_lst OUT ORDERS.TT_EQUIPMENT_OPERATION_LST, --SQL Type
av_message OUT VARCHAR2
IS
wt_dominio_lst CONTROL_EQUIPMENT.NP_CONTROL_EQUIPMENT_PKG.TT_TR_EQUIPMENT_OPERATION_LST; --PL/SQL Type
BEGIN
SP_GET_EQUIPMENT_OPERATION_LST(an_npequipstatid, wt_dominio_lst, av_message);
IF av_message IS NULL THEN
at_dominio_lst := ORDERS.TT_EQUIPMENT_OPERATION_LST(ORDERS.TO_EQUIPMENT_OPERATION('','','','','','',''));
at_dominio_lst.EXTEND(wt_dominio_lst.COUNT - 1);
FOR i IN 1..wt_dominio_lst.COUNT LOOP
at_dominio_lst(i) := ORDERS.TO_EQUIPMENT_OPERATION(wt_dominio_lst(i).wn_npequipmentoperid,
wt_dominio_lst(i).wv_npactiveservicenumber,
wt_dominio_lst(i).wv_npspecification,
wt_dominio_lst(i).wv_nptype,
wt_dominio_lst(i).wn_nporderid,
wt_dominio_lst(i).wn_npguidenumber,
wt_dominio_lst(i).wd_npdevolutionprogramdate
END LOOP;
END IF;
END;
I would like that the CAST is direct. Somebody can help me?. Thank you so much!

I am facing the same problem as u had...may I know how u solved ur probkem...

Mapping JDBC and SQL types

Hi, I've got the following problem - I write program that communicates with PostgreSQL-Server. Everything is ok, but the database has been designed not in the best way and there's no way to change it now. Furthermore they have stored procedures that contain specific data types. And I've got the problems with these stored procedures. Look the procedure has a header:
send2db(macaddr, int8, float4, timestamp)
The problem is that I haven't found any compatible JDBC-type for macaddr. And it's not the worst - I don't know how to send arrays. I know that server accepts all these types simply like Strings in the form (for example for _timestamp):
'{"2005-4-15 15:3:4","2005-4-15 15:3:8","2005-4-15 15:3:28"}'
But if I send these Stings, I get the error from the server.
For Java I have the following code:
CallableStatement cstmn = db.prepareCall("{?=call send2db(?,?,?,?)}");
      cstmn.registerOutParameter(1, Types.INTEGER);
      cstmn.setString(2,macaddr);
      cstmn.setInt(3,verytemp);
      cstmn.setString(4,tvalues_array);
      cstmn.setString(5,date_array);
      cstmn.execute();
      result = cstmn.getInt(1);

Since java extracts away the platform dependence it is less important what platform you work on.
In theory an application (web or not) should work with out modification on a solaris machine a windows pc or even a mac. That is not to say that you would want to run your web server off a mac g4 though. Use the best machine for the job. It is not the machine but all the software that goes with it that matters more.
The database is also much less of a problem because you interact with it through JDBC rather then directly. Hence, in theory (again), you should be able to switch the database and not change any code. This means the choice of SQLServer over Oracle over MySQL is less of an issue again. Databases are not as well extracted as the machine and often you have to change code to switch database but if you understand this from the start even that will mean only minor changes.

Matching data types b/w oracle and sql server

How to identify listeners types for forms, items and events in addon wizard

Dear users,
I have developed a sample addon through B1DE wizards and successfully installed and connected the addon and can view menu and form of my addon. Since i am new to this, i didn't add any listeners to my form, items and events because i don't know what type of listeners to add and what coding to add after adding listeners.
If anyone describe me how to work with listeners, i would be glad. My form has basic fields like BPcode, BPname, Docnum, Itemcode, Item name, quanity, price, total etc. Uptil now my addon form has no function of getting list of BP and Items and calculating the totals based on price and quantity but it has some basic functions like add, update,del, add print view, next record previous, record next etc. which are due to object registration and auto-code generation wizards i think.
Please help me in adding listeners and their relevant coding.
Thanks in advance.

Thanks for reply, Actually I am asking about listeners in the wizard of B1DE, code generator wizard. I think you are telling me about adding listeners directly in the vb.net. Kindly, tell me first, what event type I should add for item, form etc while adding listeners during the wizard. Or If you know some link where event types of listeners are decribed, you are more than welcome.
Thanks,
Farhan

Table to link FI document number, line item and pricing condition type

Hi,
I am looking for tables to link the FI document number, line item and PO pricing condition type.
Appreciate any help on this.
Thanks.

For any PO in ME23n in which Goods receipt has happened, you can check in the itemdetails->Po history tab in ME23n.
Here you will find the material document number. Just click on the material document, it will take you to anpther screen here you will find a button for FI document.
Click that button for FI document. In PO history istelf you can see the Condition types.
Hope this helps.

Item category (Customized )ZJT1 and MRP type for material is not allowed

Hi Guys,
When i try to create the order i see the error as item category and MRP type of the material is not allowed.
I checked in Vov5 table, i could observe that Schedule line category is maintained.
Could you please help us in resolving this..
Thanks and regards,
Rahul

Hi,
Please assign the Item Category ZJTI and MRP type (for eg: PD) assigned to the schedule line category in IMG under Sales and Distribution--> Sales ---> Schedule line -->Assign schedule line
Hope this resolve your issue

Item Category and MRP type for material is not allowed

Hello all,
I got a Error Message:
Transaction Z113 is not defined (Message no. V1347)
Diagnosis
This combination of item category Z113 and MRP type for material is not allowed.
System response
The system does not allow further processing of this item.
Procedure
Check your entry.
You can display the combination defined in table TVEPZ, which controls scheduling line category determination, and change it as required if you have the authorization to do so. The MRP type for the material may be changed in the material master.
The SD Configuration seems all right, I have:
Sls Doc Type (VOV8) ZA9 (no delivery type assigned)
Item Category (VOV7) Z113
Assigs Sls Doc & Item Ctgry (VOV4) ZA9/ZNOR/blank/blanl/Z113
ZNOR = Std Item-Av. chck Del
ZNOR defined in MM03/Sls Org 2
Define Schedule Line (VOV6) = Z7 (without delivery)
Z7 has FLAG on Prod Allocation
Assign Schedule Line (VOV5) = Z113/ND/Z7
At table: TVEPZ
I have the entry: Z113/ND/Z7
Guys, what would?
Please help me out because I am stuck in this issue.
Thanks a lot,
Barbara

Barbara, this may be tied to Strategy Group on the Material Master (I can't read enough into the detail)
Item Category determination + MRP Type for your schedule line type ties to a Sched. Line category(this you know)
New Rqmts class gets tied to a Rqmts Type
New Rqmts Type gets assigned to rqmts class
Strategy, assign the Rqmts Type to it
Strategy Group, Assign the Strategy to it
MM02 [MRP3 view] strategy group should be the one that ties together (all the other ties
It may be something in this area that you need to trace through ?

Java.sql.types and oracletypes

There appear to be difference in the way the constants are mapped in java.sql.types vs oracletypes(). For example date is '91' in oracletypes and '93' in java.sql.types. The DatabaseMetaData.getColumns() function reports data_type as a java.sql.type. Is there any mapping available from one to the other.
Thanks

Erm,
One way to find out, I reckon.
Good Luck,
Avi.

T-SQL and CLR types for return value do not match

Hi I am trying to create a CLR function to call a webservice, the CLR function return data type is double, whether I try
to create this as a table valued funcion or a scalar to return a distance travelled value I am receiving the error below. I've tried changing data types around in the CLR side and the SQL side but keep receiving the same error message, any help would be appreciated,

You defined at table-valued CLR function, but I think you meant to define a scalar CLR function. That might be the cause of the error.
RETURNS TABLE (Distance float)
should be
RETURNS (Distance float)

BI - Purchase document's item level contion type and correspondingvalue.

Dear Experts
I would like to know - Is there any standard data source in BI for item level condition type and values of Purchase order document. These are available in SAP R/3 . Shall be grateful, if you could kindly help me out
Kind regards - P.L.Dey

Hi,
Actually, These informations are stored in Characteristics and Key Figures i.e., CVCs(characteristic value combinations)
When you do Purchase Order,
These Values will store in PURCHIS ( Purchasing Information Systems) and that to, in Open Information Warehouse Data base in the form of CVCs. (In Particular Table forms)
EG.,
Values are stored in Key Figures (Eg., Number....)
Names are stored in Characteristics ( Eg., Purchase order..)
in CVC, we can easily see, Number of purchase orders for vendor, or so.....
Hopes it is useful
Thanks.

Inconsistent java and sql object types

Hi,
I have run into error "Inconsistent java and sql object types"
while mapping a java class to a sql object type. The java class
is just a duplicate of sql data structure and I pretty much
follow the JDBC Developer's GUide's examples (20-43 to 20-45)
to create the mapping java class.
Any one runs into simliar problem or any clues?
Thanks,

The safest way would be to use JPublisher to generate the type classes. In your application, you can just use the generated code to manipulate the object.

Item Type and Service Type in Sales Order

Hi All,
How do i enter Item Type and Service Type in single sales order..?
Any suggestion please...

Hi
If you select the Item type you have choose the list of Items else it is service type you can give service description and choose belongs to G/L Acc.
Or You can create a service as a Item with Item group as Service.
Hope it helps you.

The java and sql object type was not matched

My table(Oracle10.2) has a varying arrays column. For mapping to java classes, I use JDeveloper(10.1.3.1.0) to generate java classes. Then I try to insert a record into this varrying arrays column with java. While it always complaints java.sql.SQLException.the java and sql object type was not matched. I can not find the reason.
