Working with timestamp data type.

Hi all!,
I have some problems working with the timestamp data type.
Let's say that i have a table named order, where i store (in two timestamps) the date where the order was made, and the date where the order was executed.
I want:
1) first to find the difference between these to timestamps, let me call them a,b,
2) to find the average time of the difference of timestamps. With that i mean if my table has 60 typles for examples to get (b-a)/60.
Can these happen?
Thanks in advance,

I would do this with a view and a stored procedure within oracle.
Create a view that contains the two timestamp fields & the difference between them (along with any primary keys from the original table), then use this view in a stored procedure to average the values.

Queries involving where clause with timestamp data type

I need to use milliseconds in my tables and do queries where I compare the time in the table to a specific time. I changed the column to the TIMESTAMP data type (from DATE) to accommodate the milliseconds.
I am accessing the data via a C++ program using ODBC to access the Oracle 10g XE database and a SQLBindParameter statement to set up the comparisons.
Below is a table that looks like mine but simplified to just a few fields:
. DATA_ID NOT NULL NUMBER(10)
. START_TIME NOT NULL TIMESTAMP(6)
. STOP_TIME NOT NULL TIMESTAMP(6)
My query is:
. string sql("select "\
. "to_Char(rv.start_time, 'YYYYMMDD HH24:MI:SS.FF3'), "\
. "to_Char(rv.stop_time, 'YYYYMMDD HH24:MI:SS.FF3'), "\
. "rv.data_id "\
. "from "\
. "Reservation rv "\
. "where "\
. "rv.data_id = ? and "\
. "rv.stop_time >= to_timestamp(?, 'YYYYMMDD HH24:MI:SS.FF3') and "\
. "rv.start_time <= to_timestamp(?, 'YYYYMMDD HH24:MI:SS.FF3');");
MY C++ code (minus the usual statement preparation material) is:
. string startTime("20090826 15:42:02.000");
. string stopTime("20110828 02:04:52.000");
. SQLRETURN rc = SQL_SUCCESS;
. SQLINTEGER sqlRsrcInstanceId = resource->getResourceInstanceId();
. SQLLEN sqlRsrcInstanceIdLI = 0;
. rc |= SQLBindParameter( stmtHandle, 1, SQL_PARAM_INPUT,
. SQL_C_LONG, SQL_INTEGER, 0, 0,
. &sqlRsrcInstanceId, 0, &sqlRsrcInstanceIdLI );
. SQLCHAR sqlStartTime[24];
. memset(sqlStartTime, 0, 24);
. SQLLEN sqlStartTimeLI = SQL_NTS;
. strncpy( (char*)sqlStartTime, startTime, 23);
. rc |= SQLBindParameter( stmtHandle, 2, SQL_PARAM_INPUT,
. SQL_C_CHAR, SQL_CHAR,
. sizeof(sqlStartTime)-1, 0,
. &sqlStartTime, sizeof(sqlStartTime)-1,
. &sqlStartTimeLI);
. SQLCHAR sqlStopTime[24];
. memset(sqlStopTime, 0, 24);
. SQLLEN sqlStopTimeLI = SQL_NTS;
. strncpy( (char*)sqlStopTime, stopTime, 23);
. rc |= SQLBindParameter( stmtHandle, 3, SQL_PARAM_INPUT,
. SQL_C_CHAR, SQL_CHAR,
. sizeof(sqlStopTime)-1, 0,
. &sqlStopTime, sizeof(sqlStopTime)-1,
. &sqlStopTimeLI);
When the statement is executed, I get the following error:
. ODBC Return Code: SQL Error.
. Native Error Code/Message:
. 932/[Oracle][ODBC][Ora]ORA-00932: inconsistent datatypes: expected - got -
Any suggestions on what is wrong or a better way to perform the query?

The only way to test a query is to get out of your environment and fire up SQL*Plus (command line).
I can not read all of what you wrote but the error you are generating should show up there along with sufficient information to quickly fix it.
Once you have working statement put it back into your environment.

Working with complex data types in web services ...

Hi All,
I have created a webservice and created an interface for that in ADF. Now as my web service returns a complex data type, i followed the steps given in this article "http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html" and it works fine, my results also get displayed. But only issue is i get a warning "JBO-25009: Cannot create an object of type:java.util.calendar with value:2008-09-23T23:51:30.000+05:30" and if i replace all the java.util.Date with oracle.jbo.domain.Date then i get a warning "JBO-25009: Cannot create an object of type:oracle.jbo.domain.Date with value:2008-09-23T23:51:30.000+05:30". Now i am unable to understand this although i believe it is a data type mapping issue, but not sure how to rectify it.
Anybody knows the wayout?
Regards
Lokesh

Andre,
Thanks for youe response. I also tried makeing data type as string in place of date in data control.xml and it worked fine. So it confirms that i am facing with exactly similar issue as yours.
I tried solution 2 mentioned in Frank's mail but its not helping[in fact i am already using web proxy as i am delaing with complex data types]. I created a web proxy and in java bean i placed break points to check the control flow[in order to check the root cause] but control never reaches the java bean!! I am not sure about the cause for it...control should pass through java bean isn't it??
I am quite new to SOA...so can somebody just elaborate on how to rectify this using web proxy. I have been using this rl "http://www.oracle.com/technology/products/jdev/howtos/1013/wsadf/adfcomplexwstypes.html" to work with web proxies" to work with proxies.

Required attribute does not work with any data type other than String

sir,
I am a new to JSF. My problem is that I have used an integer type data in my page which is taking its value from a bean.But in jsf code I have used the required attribute for the <h:inputText> but if I leave the text box empty it is not showing the validation error which it show show. Another problem is that the page is also not navigating to the next page.
The code is
<h:inputText value="#{UserBean.age}" required="true"/>
where age is of integer type

Well. The fact that it is not jumping to the next view is "works as required". The assumption is, that once you say a field is required, it could be that the application CANNOT function without that value. Therefor the initial view is redisplayed until all required values are entered.
IF you need a different behaviour, then the OptionalValidator-package which is currently in development state, is the way to go. It allows to specify different validating strategies for different links on a view (no validation, soft validation (== allow to go on, but produce warning messages), hard validation (== the way JSF works right now)). The problem is that with JSF 1.1 it is quite difficult to implement this behaviour. For simple validators (no parameters) it is working, but for complex validators (requiring parameters) not yet. For more info: http://wiki.apache.org/myfaces/OptionalValidationFramework
No comment on the String-only behaviour, as I have not yet tested/observed that problem...

Same Input name with different data type cause the reflection exception

I have a proxy contains couple RFCs. Two RFCs contain an argument named IN_COMPANY_CODE with data type of ZTRE_FX_BUKRSTable. Another RFC contains the same argument name of IN_COMPANY_CODE but hold different data type (String). All RFCs are in the same proxy. Complie and build the application with no issue.
But when I ran the RFC, it generates the reflection exception below:
Method SAPProxy1.Z_F_Tre_R_Pre_Trade_Fx can not be reflected. --> There was an error reflecting 'In_Company_Code'. > The XML element named 'IN_5fCOMPANY_--5fCODE' from namespace '' references distinct types System.String and MSTRFOREX.ZTRE_FX_BUKRSTable. Use XML attributes to specify another XML name or namespace for the element or types.
I realize the conflict introduced by the same name with difference data type. But I would like to know if this is fixable as a bug or if there is any best practice and/or some manual intervention to make it work.

Please install fix from OSS note 506603. After this, right-click .sapwsdl file and select "Run custom tool".

Call a method with complex data type from a DLL file

Hi,
I have a win32 API with a dll file, and I am trying to call some methods from it in the labview. To do this, I used the import library wizard, and everything is working as expected. The only problem which I have is with a method with complex data type as return type (a vector). According to this link, import library wizard can not import methods with complex data type.
The name of this method is this: const std::vector< BlackfinInterfaces::Count > Counts ()
where Count is a structure defined as below:
struct Count
Count() : countTime(0) {}
std::vector<unsigned long> countLines;
time_t countTime;
It seems that I should manually use the Call Library Function Node. How can I configure parameters for the above method?

You cannot configure Call Library Function Node to call this function. LabVIEW has no way to pass a C++ class such as vector to a DLL.

JDBC insert with XMLTYPE data type

Hi,
SOAP to JDBC scenario. Oracle 11G as a receiver.
Requirement is to insert whole xml payload message in one of Oracle table fields as a xml string. Target oracle DB table column is defined with XMLTYPE data type, it has capacity to hold xml data more than 4GB. I am using graphical mapping with direct INSERT statement.
When I try to insert xml payload with smaller size transaction goes through. However when the xml payload size increases it is giving following error in JDBC receiver communication channel monitoring.
Could not execute statement for table/stored proc. "TABLE_NAME" (structure "StructName") due to java.sql.SQLException: ORA-01704: string literal too long
Here is insert statement as in communication channel monitoring. (Note: XML payload with bold characters is truncated)
INSERT INTO TABLE_NAME (REQ_ID, OUTAGE_OBJ, TIMESTAMP, PROCESSED_FLAG) VALUES (VAL1, <?xml version="1.0" encoding="UTF-8"?>............</>, TO_DATE(2010-11-15 10:21:52,YYYY-MM-DD HH24:MI:SS), N)
Any suggestions to handle this requirement?
Thank you in advance.
Anand More.

Hi Anand,
The problem here is definitely the length of the SQL query. i.e "INSERT INTO ......... VALUES......."
This is what i got when i searched for this ORACLE error code:
ORA-01704: string literal too long
Cause: The string literal is longer than 4000 characters.
Action: Use a string literal of at most 4000 characters. Longer values may only be entered using bind variables.
Please ask a ORACLE DB expert on how to handle this Also i am not sure how can we handle Bind Varibales in SAP PI.
I hope this helps.
Regards, Gaurav.

Check box with Boolean data type is not behaving properly

Hi,
I create a sample application with one entity driven view object with two attributes. One is of String data type [Value will be Y/N] and another (transient) attribute with Boolean data type. I planned to bind this boolean data type attribute to UI. I overridded the view row impl class and included setting of boolean attribute inside the setter of String attribute. Also in the getter of boolean attribute, added code to check the string attribute and return true/false based on that. Everything is working fine in application module tester. But when i test the same in view controller project in a page, it is not working. Always Check box component is not checked eventhough when i explicitly check it.
[NOTE: I have given the control hint of Boolean attribute as check_box. Also i don't want selected/unselected entries in the page def file. That's why followed this approach]
Have i missed out anything? Why this behaviour.
Thanks in advance.
Raguraman

what is the value that is going in when u check it.. did u debug it.. is the viewRowimps setter and getter getting called.. and is it having the right value set and got.. and ur sure that ur using selectBooleanCheckBox..
ur binding the checkbox to the transient value right??

Migrating Sybase "timestamp" data type to Oracle DB

Hi,
We are migrating huge Application currently running on Sybase database
to Oracle 10.2.0.3 (500+ Tables and Stored Procedures).
Have following questions regarding this Migration.
1) Many of the Sybase Tables have column which is of Sybase data type "timestamp".
Do you have any recommendation what is the data type to be used in Oracle for
migrating "timestamp" data type in Sybase?
2) How should we migrate existing data and business logic residing in Sybase for
data columns of Sybase data type "timestamp" ?
Given below are details on how we use Sybase timestamp Column in our Application
and we are trying to arrive at the best Solution that is possible for migrating
all those Tables and related business logic to Oracle.
We have following Control Table in Sybase which has column of timestamp data type and
some other Business keys.
sp_help EQP_IES_CRE_TIMESTAMP (This is similar to desc <table> command in Oracle)
EQP_IES_CRE_TIMESTAMP,dbo,user table
default,Nov 14 2001 10:39AM
CRE_TIMESTAMP ,timestamp,8,,,0,,,,0
REF_NUM ,char,30,,,0,,,,0
REC_UPD_DT ,datetime,8,,,1,,,,0
EQP_IES_CRE_TIMESTAMPI1,clustered, unique located on default, CRE_TIMESTAMP, REF_NUM, REC_UPD_DT,0,0,0,
Following is the overall logic used in Sybase
-- Step 1: Based on Event, populate Control Table with new Row.
-- CRE_TIMESTAMP timestamp Column gets auto-populated by Sybase
insert EQP_IES_CRE_TIMESTAMP (REF_NUM, REC_UPD_DT)
values (@uuid_ref_num, @event_cre_dt)
Since CRE_TIMESTAMP is auto-populated, it does not appear in above INSERT statement.
-- Step 2: Store timestamp value populated by Sybase in previous step,
-- to variable @event_timestamp. This value would be referenced
-- later in other SQL statements
select @event_timestamp = CRE_TIMESTAMP
from EQP_IES_CRE_TIMESTAMP
where REF_NUM = @uuid_ref_num
and REC_UPD_DT = @event_cre_dt
-- Sample value for @event_timestamp could be '001c0000182f2089'
-- It is not very readable or understandable
-- Step 3: Delete Control Table entry made in Step 1
delete EQP_IES_CRE_TIMESTAMP from EQP_IES_CRE_TIMESTAMP
where CRE_TIMESTAMP = @event_timestamp
-- Step 4: Make use of saved timestamp value from Step 2 to trigger queries
-- against other Tables that have timestamp Columns
-- Some sample queries are as shown below
delete eqp_staging
where event_timestamp > @event_timestamp;
insert into eqp_movement values(@event_timestamp, ......other columns) ;
Any idea how above Table and logic could be migrated to Oracle DB
We would also like to know how data values that currently exist
in Sybase Tables should be populated in Oracle .
Any suggestions or tips would be greatly appreciated
Thanks
Auroprem

Hi All,
Thanks for your responses.
We have decided on Solution to migrate "timestamp" Column from Sybase to Oracle, that is
specific to our Application needs.
Following is what we decided:
1) Create RAW Column in Oracle which would contain data Replicated from Sybase "timestamp" Column as is.
2) Create additional Column of INTEGER data type to store number equivalent of Sybase "timestamp" column
which would be more usable and consummable in Oracle as compared to RAW datatype.
3) Write Row-Level INSERT/UPDATE Trigger on migrated Oracle Table to populate INTEGER Column using
SQL Function TO_NUMBER(<raw_column_value>, 'xxxxxxxx').
4) Applications that access this Table, upon migration to Oracle, will now start referencing INTEGER Column
newly defined, and populated via Trigger.
Please let us know if you see any issues with this approach
Thanks

How to add TIMESTAMP data type in Enterprise Architect...?

Hi all
There is no data type of timestamp in Enterprise Architech. There is only
DATE type. I have ERD prepared from Enterprise Architech. How to modify
DATE type to TIMESTAMP type.
How to add TIMESTAMP data type in Enterprise Architect or in ERD ?
Thanks in advance,
Pal

Have you asked this question of the vendor of Enterprise Architect? They may have a later version that supports the various TIMESTAMP data types. If your ERD tool doesn't support a data type, other than talking to the vendor or working around the problem (i.e. generate DDL to a text file and edit it before applying it to the database), you're probably out of luck.

Error ORA-01426: numeric overflow when Creating table with double data type

Hi,
I am using ODP.NET to create a table with data from SQL to Oracle. The problem is with double data type fields that is equivalent to FLOAT(49) in Oracle. My syntax is:

Ho to Comapre with Number Data Type

hi
My reqt is to do validation in ValidateEntity Method.
How to compare the with Number Data type:

So plz tell me how to compare the integer value with Number data type
Thanx

Check with float. It will work definitely.
float number = Float.parseFloat(HrsPerDay); //HrsPerDay is a String and I am converting it to float
if(( number <= 0) || (number >= 21))
                        throw new OAAttrValException(OAAttrValException.TYP_VIEW_OBJECT,

Creating Web service for PL/SQL Procedure with Complex Data Types

I need to created web service for PL/SQL Procedure with Complex Data types like table of records as parameters, how do we map the pl/sql table type parameters with web service, how to go about these?

Hello,
When you are creating a service from a Stored Procedure, the OracleAS WS tools will create necessary Java and PL wrapper code to handle the complex types (table of record) properly and make them compatible with XML format for SOAP messages.
So what you should do is to use JDeveloper or WSA command line, to create a service from your store procedure and you will see that most of the work will be done for you.
You can find more information in the:
- Developing Web Services that Expose Database Resources
chapter of the Web Service Developer's guide.

My iPad Mini with retina display suddenly will not connect to the Internet. It shows full wifi bars, yet no web pages will load. My Internet is working with all other apple devices in my house. The iPad also no longer works with celluar data.

My iPad Mini with retina display suddenly will not connect to the Internet. It shows full wifi bars, yet no web pages will load. My Internet is working with all other apple devices in my house. The iPad also no longer works with celluar data. I'm not sure what has happened. It was working fine a few hours ago. I have tried resetting it, ive restarted my browser etc. I tried to erase all data from my Ipad but I can't do that because it needs to sign into my Apple ID and use the Internet!

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are drooping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button
