ADF Business Component Type MAP Oracls vs Java

what the advantages and disadvantages from each one map type
thank in advance

Take a look at this link in developer's guide:
http://docs.oracle.com/cd/E16162_01/web.1112/e16182/bcintro.htm#sm0062
The Java Extended for Oracle type map and the Oracle Domains type map handle numeric data differently. When you create a new application the default type map Java Extended for Oracle maps numeric data to the java.math.BigDecimal >class, which inherits from java.math.Number. The java.math.BigDecimal default matches the way the Fusion web application view layer, consisting of ADF Faces components, preserves alignment of numeric data (such as numeric values >displayed by ADF Faces input fields in a web page). Whereas the Oracle Domains type map, which maps numeric data to the oracle.jbo.domain.Number class, may not display the data with the alignment expected by certain ADF Faces >components. Aside from this alignment issue, the Oracle Domains type map remains a valid choice and applications without ADF Faces components will function without issue.Thanks,

SQL user defined type mapping with Java Class type

SECRET_TAB_TYPE is userdefined type in SQL Schema. but accessing this way it is giving invalid column type error(see code below )??
I have made a class with same name attributes as in SQL Type
Connection con = DriverManager.getConnection(URL,Username, Password );
java.util.Map map = con.getTypeMap();
map.put("SchemaName.SECRET_TAB_TYPE",Class.forName("SECRET_TAB_TYPE"));
CallableStatement pstmt = con.prepareCall( "{ call smartapi.FetchSharedSecret(?,?,?,?,?,?) }" );
pstmt.setString(1,"SM");
pstmt.setString(2,"BT");
pstmt.setString(3,"COM");
pstmt.registerOutParameter(4, Types.JAVA_OBJECT);//
pstmt.registerOutParameter(5,Types.VARCHAR);
pstmt.executeQuery();
secret_tab=(SECRET_TAB_TYPE)pstmt.getObject(4);
message= pstmt.getString(5);

Mapping Oracle/Java

HI,
This is my problem : I have a field in a table containg VARCHAR2. The field is a pasword and may contain ASCII codes < 30.
I retrieve the value in a oracle.sql.CHAR type variable. I want to sent this value to client. BUT, oracle.sql.CHAR is not serializable so I must extract the value from the variable. But extracting seems to lose something from the information : some positions are not correctly decoded.
The DB is using the oracle-.......-871 Character set.
In which form can I send that information to the client in order to recompose the password correctly at the client?
Thank you!

Image type mapping

Could anyone simply tell me what is the image file type mapping in java ,JDBC, DB2 database?

Hi,
My java web application has a function to upload image and store into DB2 database through ibatis sqlmap which is based on JDBC. So Could anyone
tell me what is the image type mapping between java,JDBC and DB2? what is other concerns about this? currently I use BLOB in DB2. byte[] in java. but DB2Exception is throwed.

Does the Number type in Oracle always map to the Java BigDecimal object

We have noticed that whenever we create a column in a table of type smallint, integer, real, etc. that the type in sqlplus always shows up as number(x). Our problem is that this type always seems to map to java.math.BigDecimal through JDBC. Is this a bug in the JDBC drivers???
Put another way when I create a column of type smallint I expect that after performing a query I should be able to call the getShort method on the result set in order to get the value from the afore mentioned column. But instead I get a ClassCastException because the Java type for the column is actually a java.math.BigDecimal.

can anyone help me to solve this problem.1. Write a wrapper procedure that converts the table of dates to either number or date and then re-convert the table back into date.
2. Since it's an out param you could create a temp table, insert the contents of the index by array into it and return a cursor.
3. Create a oracle type using CREATE TYPE and then use an array of the type.

Mapping Oracle types

How can I collect in oracle the type of data "TABLE" returned by a procedure stored to utilize its data. It is to do the mapping to java.
String mp = "{call MP_Procedure(?,?)}";
// Access to database
     CallableStatement cs = (CallableStatement)con.prepareCall(mp);
     cs.setInt(1,326);
     cs.registerOutParameter(2, OracleTypes.ARRAY); ?????????????
     cs.execute();
.....

Well, in oracle database exists the type Table that is a matrix of objetcs. My database administrator use them to make stored procedure so i need to colect his contents, you know I can't explain why my database admnistrator use it, but she uses them.
So can you help me?
Sorry about my english :D

How to map Oracle ORDImage type, what is the JDBC-type ?

Hello,
I have a field in my Oracle database that has the type ORDSYS.ORDIMAGE. How can I map this in the standardjbosscmp-jdbc.xml file of JBOSS (in the part of the oracle 9i type-mappings)?
The java type is "oracle.ord.im.OrdImage", but what is the jdbc-type ? Do I have to include extra oracle files in some directories of Jboss ?
<mapping>
<java-type>oracle.ord.im.OrdImage</java-type>
<jdbc-type>?</jdbc-type>
<sql-type>?</sql-type>
</mapping>
Thanks!!!
Greetz J

I've never used JBOSS, but, could the jsbc type indicate the jdbc driver to use?
The sql type is ORDSYS.ORDIMAGE, but I am not sure what JBOSS is looking for...

Data Type Mapping from SQL server to Oracle

I am using Oracle 12c with heterogenous services connecting to SQL server DB. Some of the columns in the SQL server SB are defined as 'nvarchar(max)'. These are coming over to Oracle as 'long' type columns. I would like these to be 'varchar2' types in Oracle so I do not have any of the restrictions related to 'long' type fields when using. I can create a view in SQlServer to convert the data type ie. nvarchar(100). What is the highest value I can use to make the data show in Oracle as varchar? BTW I tried nvarchar(4000) but that still showed as long. I tried nvarchar(1000), and that did show as varchar.

The maximum value for a nvarchar2 in Oracle is 2000. The mapping -if the remote column is mapped to an Oracle varchar/nvarchar- depends on the data type returned by the ODBC driver. When the driver returns SQL_Varchar, then the maximum precision is 4000 and when it will map it to SQL_WVarchar then it is 2000.
As your Oracle database uses AL32UTF8 as character set you will get the nvarchar(max) mapped to Oracle longs as the content of your SQL Server nvarchar is stored using UCS2 character set which is covered by the Oracle database charset UTF8. So it shouldn't really matter if the returned string is mapped to an Oracle varchar or nvarchar.

Java Type mapping of NUMBER columns

I'm using JDBC Oracle driver 10.2.0.4, with java 1.5 and Oracle 10.2.0.4.
Reading a field of NUMBER(6) JDBC driver map it to java.lang.Integer, if I extend this column to NUMBER(9) Jdbc map it to java.lang.Long.
When can I find a detailed documentation of Number mapping, i found some documentation for general field mapping but is not exhaustive about NUMBER fields and this behavior is not documented.
Thanks
Carlo

That is all database/driver specific. So you have figure it out using what is in the Oracle java classes. There is no generic jdbc solution. If you are lucky the Oracle docs for the driver might document something useful.
If it was me I would just wrap another proc around it and have that strip the fields out for me and return it as a regular result set.

The JNI defines a mapping of Java types and native (C/C++) types.

As per the tutorial
The JNI defines a mapping of Java types and native (C/C++) types.Does the above sentence mean that I can use dll written in C/C++ only and not dll written in Pearl.
Could anyone please give me the solution.

Please do tell me how can I call a dll file created in Perl ....And I will point out again that I doubt that it is possible to create a dll that has the following characteristics
1. Is in fact a dll.
2. Is in fact intended to run anywhere outside of the perl engine.
Step 2 means that you run perl, not a "perl dll" via C.
You can do that or at least in the past you could. And that has nothing to do with java nor JNI. So you would learn about it on a perl site.
And I can only note that when I did that a number of years ago it was very difficult. Certainly much harder than getting JNI to work. And you had better have quite a bit of C/C++ experience before you attempt it.

Oracle to ODBC data type mapping

Hi all.
I am currently using an EasySoft ODBC driver to connect to 10g. This gives me the ability to map oracle data types to ODBC:
0 NUMBER <= 4 digits SQL_SMALLINT
NUMBER <= 9 digits SQL_INTEGER
NUMBER <= 19 digits SQL_BIGINT
NUMBER = n digits SQL_NUMERIC
NUMBER = n,m digits SQL_NUMERIC
1 NUMBER <= 4 digits SQL_SMALLINT
NUMBER <= 9 digits SQL_INTEGER
NUMBER = n digits SQL_DOUBLE
NUMBER = n,m digits SQL_DOUBLE
2 NUMBER <= 4 digits SQL_SMALLINT
NUMBER = n digits SQL_INTEGER
NUMBER <= 19 digits SQL_BIGINT
NUMBER n,m digits SQL_DOUBLE
I would rather use the Oracle ODBC driver but I am unsure how (read if) I can get these values mapped?
Any help would be much appreciated.

Hi,
Could you re-run with CQLProcessor category set to DEBUG?
Which version of OCEP is it?
Thanks,
