Table Name on JDBC
Hi Experts,
If I am working on a outbound interface using JDBC (SAP to ODS) on direct insert and update, how can we check the target table name of ODS? I believe it's in somewhere of my Message Type or Message Interface? Or is it at the Communication Channel? I have no idea how can I look for it after several try and error.
Example, the table SAP_INVOICE in ODS is ready for SAP to pump in data, where can I get the SAP_INVOICE value in my XI?
Thanks.
Cheers,
Isaac.
Refer this link : [JDBC Message Format|http://help.sap.com/saphelp_nw04/Helpdata/EN/2e/96fd3f2d14e869e10000000a155106/content.htm]
Check the JDBC receiver Message Type.
Or check converted XML in Communication Channel Monitoring (for JDBC).
Thanks

Table name in Receiver JDBC Adapter
Hi All,
I am using receiver JDBC adapter.
But table name consist of " like BPC."#II" .
After mapping table name becomes BPC."#II" .
I am getting error while pulling data from DB.
Is the table name creating a problem.
Please remedy of this if you have come across such scenario.

All that i could get from the SAP Help regarding JDBC Adapters are these links where i never found anything much regarding the table name.anyways just go through these links and see if you find anything useful.

- Escape Symbol for Apostrophe
The apostrophe character () is a reserved character in SQL syntax and is therefore replaced by an escape character if it occurs within value strings. This replacement character can be database-specific. Typical replacement characters are \ or (default value). If a character occurs that is invalid for the database being used, the adapter triggers an error message (an SQL exception) concerning the SQL syntax that is generated by the database.
- Column Name Delimiter
Depending on the database being used, column names can be enclosed by a special delimiter character, for example, if the names can contain special characters (such as ). This character can be specified at this point. The default setting is no delimiter character. If a character occurs that i

Referencing table-aliased column names in JDBC
We are attempting to port an application from MySQL to Oracle 8i, using JDBC as the database connection technology. The app has SQL statements using joins, e.g.
SELECT A.*, B.* FROM table1 A, table2 B WHERE A.field1=B.field2 etc
Often the tables have columns sharing the same name, so the table alias is required to avoid ambiguity (e.g. both tables have column ID, so they must be referenced as A.ID or B.ID).
When using MySQL, the Java code
String strField = rset.getString( "SURNAME" );
or
String strField = rset.getString( "A.SURNAME" );
both succeed if the column name is unique, and if it is not unique, only the second form works. However, with Oracle, the second form never works, even though the column name is a valid column in the table aliased as A. Providing the whole table name does not work either:
String strField = rset.getString( "table1.SURNAME" );
If the Oracle JDBC driver does not support the {table-alias}.{column-name} syntax, then presumably the only way to reference ambiguous columns in joins is to supply the column number instead. (e.g. getString( 14 )). Our application generates dynamic SQL, and having to do this would be a MAJOR problem.
We are currently using Oracle 8i - might this have been fixed in the move to 9i?
Many thanks for any help,
Steve Francis,
London, UK.Can't do it by alias, as you would just repeat the
calculation/function/whatever and add whatever additional "stuff"
to create your new column.
ISNULL(row1, 99999) AS ideal,
ISNULL(row1, 99999)+10 AS newideal
etc.

Jdbc bug in executeUpdate(sql, int[]) when table name is case-sensitive;
I have found a bug in oracle's jdbc (ojdbc6.jar), can someone tell me how to submit it so that it can be fixed?
The BUG: using executeUpdate(insert_sql_stmt, int[]) to retrieve the generatedKey generated by before-insert trigger using a sequence results in error when the tablename is case-sensitive (but OK if table name in uppercase).
Steps to reproduce:
1a. create table "mixCase" (f1 integer, f2 varchar2(20));
1b. create table upperCase (f1 integer, f2 varchar2(20));
2a. create sequence mixCase_seq start with 1;
2b. create sequence upperCase seq start with 1;
3a. create or replace trigger mixCase_trigger before insert on "mixCase"
bq. for each row \\ begin \\ select mixCase_seq.nextval into :new.f1 from dual; \\ end;
3b. create or replace trigger upperCase_trigger before insert on upperCase
bq. for each row \\ begin \\ select upperCase_seq.nextval into :new.f1 from dual; \\ end;
4a. String url = "jdbc:oracle:thin:@//localhost:1521/orcl";
bq. conn=DriverManager.getConnection(url,user,password); \\ Statement stmt = conn.createStatement (); \\ int rc=stmt.executeUpdate("insert into \"mixCase\"(f2) values('aa')",new int[]{1});
4b. String url = "jdbc:oracle:thin:@//localhost:1521/orcl";
bq. conn=DriverManager.getConnection(url,user,password); \\ Statement stmt = conn.createStatement (); \\ int rc=stmt.executeUpdate("insert into upperCase(f2) values('aa')",new int[]{1});
When you run 4a or 4b in a java jdbc program:
4b runs OK and rset=stmt.getGeneratedKeys() returns the correct f1 value of 1.
4a results in error:
bq. h6. java.sql.SQLSyntaxErrorException: ORA-00942: table or view does not exist \\ + at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:91)+ \\ + at oracle.jdbc.driver.DatabaseError.newSQLException(DatabaseError.java:112)+ \\ + at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:173)+ \\ + at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:455)+ \\ + at oracle.jdbc.driver.T4CTTIoer.processError(T4CTTIoer.java:406)+ \\ + ...+
+Notes:</</em>
# If Statement.RETURN_GENERATEDKEYS is used instead of "new int[]{1}" in 4b, there is no error but the rset=stmt.getGeneratedKeys() returned in a ROWID such as 'AAARUyAAEAAAAGQAAL', not what is expected. Other database's jdbc return the correct generated integer value.
# Same 4b error if new String[]{"f1"} is used as 2nd argument for executeUpdate.
# The only difference in 4a and 4b is that 4a has case-sensitive table name. All sequence names, trigger names, column names are implicitly deemed to be uppercase by oracle in both cases.

schema executible under your oracle_home bin directory.
schema 1.xml 1.xsd
for example
if it dupes in 10.2.0.3 open a TAR with support so that we may bug it.

JDBC Schema and Table Names Reversed
Hi,
We're currently evaluating CR4E but are unable to successfully run/preview any reports.
We have successfully created a JDBC connection using the generic JDBC driver. We are connecting to an Ingres database. The connection is successful and we can browse databases/schemas/tables with no problem. The problem is with the SQL that the reporting engine is generating.
A simple example:
SELECT "currency"."description" FROM "currency"."john" "currency"
In this statement, "currency" is actually the table and "john" is the schema name.
The query should read:
SELECT "currency"."description" FROM "john"."currency" "currency"
Help would be appreciated as we're completely stuck.
Many thanks,
Darran SmithHi Tej,
Thanks for clarifying the issue on the JRC.
Executing:
SELECT "price_type"."currency", "price_type"."description" FROM "price_type"."john" "price_type"
against the DB results in "Table 'john' does not exist or is not owned by you" as expected.
Executing
SELECT "price_type"."currency", "price_type"."description" FROM "john"."price_type" "price_type"
against the DB works just fine.
I amended my code to simply call:
CRJavaHelper.changeDataSource(reportClientDocument, userName, password, connectString, driverName, JNDIName);
and changed the CRJavaHelper.java file around line 145 that originally reads:
newTable.setQualifiedName (origTable.getAlias ());
I tried setting the qualified name to various different things:
"price_type"
"john.price_type"
"otherSchema.price_type"
None of these worked, but they did produce different things in the JDBC trace log. I've uploaded the JDBC log file to showing what happens with either "price_type" or "john.price_type":
[http://www.romofabrics.com/iijdbc.txt|http://www.romofabrics.com/iijdbc.txt]
As you can see, everything looks OK (including the schema and table name) until the very final select statement is created.
When you say that generic JDBC is supported, is that what I'm effectively using?
Cheers,
Darran -
Physical table name - abstract table name mapping in CMP Bean
Hello,
I am using a EJB 2.x bean deployed on a SJSAS 9 server. EJB has problem associating the EJB to the actual table
Details are as follows:
EJB name: AccountCMP
Actual tablename : account

Please note that the insert statement has the ejb-name (I think so, as my CMP EJB is called ACCOUNTCMP) instead of the actual tablename (account).
I do have the account.dbschema file and sun-cmp-mappings.xml in the NB 5.5 project, but the mappings.xml file is not included in the jar by NB. Is that expected, or an problem.

I found out the issue. sun-cmp-mappings.xml file is mandatory, and dont know why, netbeans excludes this file from the jar. I had to edit project.properties file to negate this exclusion.
Another problem was that my table did not have a primary key (and hence by schema file did not have it also). CMP bean code generator did not like this.
Once I fixed these two problems, my CMP started working fine.
Thank you all -

at java.lang.Thread.run(Thread.java:534)OK, I figured it out myself. :)
Turns out when I define the queue name in the AQ Adapter definition, I was specifying "<Default Schema>" as the schema name. When I changed this to my actual schema name (eg: "SCOTT"), it worked. Nice little bug there!
The reason it broke with the example program is because I was changing the schema name before I deployed it. As I didn't have a SCOTT schema.
So the moral of the story here is, don't use "<Default Schema>"!
I was running on 10.1.2.0.0 [build #1787 ]. In case anyone wants to fix this. -
Table name as paramter to PreparedStatement?
Can a table name be provided as a parameter to a Prepared Statement? We are using Oracle 10 and have data stored in different schemas. The tables in each schema are identical, but depending on the customer querying the database we need to view the data in one schema or another. Follows is the code we are using:
Connection con = session.connection();
PreparedStatement stmt = con.prepareStatement("select * from ?");
stmt.setString(1, customerSchema+".visit");
ResultSet rs = stmt.executeQuery();and then we get the exception:
ORA-00903: invalid table name
Is what I am trying to do possible without reverting to changing the Prepared Statement call to:
PreparedStatement stmt = con.prepareStatement("select * from " + customerSchema+ ".visit");The reason I would avoid the above code, is because we want to use Hibernate and use the mapping file for SQL statement, but the problem I have is SQL/JDBC focused, since Hibernate can't do something that JDBC can't do.
BTW I am dealing with a legacy database, so while it would be nice to correct the database design, there is too much already in place to do so at this time.I am dealing with a system where each each client is allocated a separate schema (the data is not private to the customer, so no ethics issues here). We now need to create an admin tool that can create reports, grabbing the data from the various schemas. I was hopping to be able to have an admin user that can access all the schemas, without having to list all the login names and passwords somewhere. In doing so I would be able to query each table of a given type in the various tables. So if I have a table called 'MyTable', then we would have:
SELECT * from mySchemaA.myTable
SELECT * from mySchemaB.myTable
etc
While we can argue over what was done in the past over the way the database was set up, the truth its already there and we have to deal with the result.
Currently the two alternative solutions I am looking at are:
- separate JNDI entries, in the application server, that the application needs to know about

Dynamic table creation using JDBC
hi all, i am working in JDBC and using prepared statements.the problem i have is i need to create and read from tables,dynamically and i should also create tables with keys dynamically,i.e the user gives the table name and i should create it using JDBC.the user does not enter the full query he just types the table name.i am using oracle as backend.i have tried prepared statements to retrieve datas from tables whose names r given dynamically like
"select * from ?"
and then using
setString(1,the variable which holds the table name);
but this doesnt seem to work.it says invalid table name.how can i do this.i shd also create tables the same way like
"create table ? ..."
is there a way out of this problem or is there any other type of statement that i can use.please give a detailed example.thanks in advance.Usually when I work with Oracle DBA's they get real excited when I suggest that the application could create the tables dynamically. Because this means that there is absolutely no chance that there is a coherent implemetation of table allocation.
Seemed like a good point to me. -
Need to know schema name and table name associated with a column-URGENT
Hi folks,
I need to know the schema name and the table name associated with a column. Though jdbc has the api to getTableName and getSchemaName, some database vendor like oracle does return empty upon call of mentioned methods. I found that oracle driver does not support that
Can any one give me the solution? It is urgent. Or do you suggest any third pary jdbc driver which can provide those?
Thanks
AngelinaAngelina,
Your question has been discussed several times previously in this forum. Search this forum's archives for "getTableName". Oracle JDBC driver does not implement this (because "it is not feasible" -- according to Oracle).
First of all, I would suggest that you could probably change your application's logic so that you would not need this functionality (but I guess that is not feasible either, right :-)
Alternatively, you could try querying the Oracle database data dictionary.
Good Luck,
Avi. -
Refresh tool and table name containing database name in Mysql
Hi,
when refreshing the database schema and my table name contains a database name (for example "my_other_db.my_other_table"), the refresh tool never sees weather "my_other_db.my_other_table" already exists or not. so it always generates a create-table-statement (which is syntactically correct, but of course fails, because that table exists already).
Is there known workaround for it? I am using Mysql 5.0.x, jdbc driver 5.0.7, Kodo 4.1.4 (but this problem was there before).
Right now i'm deleting the database names from my package.jdo-files, then doing the refresh command and after that i put back the database names. At runtime Kodo works very well with the database name before the table name.
Thanks very much,

Persistence two beans in the same table, Duplicate table name in different beans
Hi,
I need to persist two beans belonging to different classes in the same
table, but the following mistake happens:
[jdo-enhance] javax.jdo.JDOFatalUserException: Invalid jdbc-table-name:
Duplicate table name
There exists some way of persisting both objects in the same table?
thanks
jasabinoNo. It would be very confusing to do so. Can they not share an
inheritance hierarchy? You can use flat mapping to do so.

I am doing DataBase Lookup in XI
First i have created a Table in Database( CheckUser) which has two fields UserName and PhoneNumber and then i have created
I have created one Communication Channel For Reciever Adapter .
I have given the parameters like this
JDBC Driver : com.microsoft.jdbc.sqlserver.SQLServerDriver
Connection : jdbc:microsoft:sqlserver://10.7.1.43:1433;DatabaseName=Ravi;
UserName.... sa
password.... sa
persistence : Database
Database Table Name : CheckUser
Key column name and Value column name i left blank and activated
and then
I have created
Data Types : Source ...... UserName
Destination.... PhoneNumber
Message Types
Message Interfaces
In Message Mapping
I have created one User Defined function DBProcessing_SpecialAPI().This method will get the data from the database....
In this function i have written the following code
//write your code here
String query = " ";
Channel channel = null;
DataBaseAccessor accessor = null;
DataBaseResult resultSet = null;
query = "select Password from CheckUser where UserName = ' " +UserName[0]+ " ' ";
try {
channel = LookupService.getChannel("Ravi","CC_JDBC");
accessor = LookupService.getDataBaseAccessor(channel);
resultSet = accessor.execute(query);
for(Iterator rows = resultSet.getRows();rows.hasNext();){
Map rowMap = (Map)rows.next();
result.addValue((String)rowMap.get("Password"));
catch(Exception e){
result.addValue(e.getMessage());
finally{
try{
if(accessor != null)
accessor.close();
}catch(Exception e){
result.addValue(e.getMessage());
And the i have mapped like this
UserName -
> DBProcessing_SpecialAPI----
>PhoneNumber
when i am testing this mapping i am getting the following error
