We have a legacy application we cannot modify that connects to Oracle 11g and at some point runs a query and returns a result. The application however is using the "generated" column name from Oracle to read the result.
Consider the following query:
select nvl(1,0.0) from DUAL;
As this query does not specify an alias, the generated column name would be "nvl(1,0.0)"
However on another server the generated column name is "nvl(1,0)" (notice 0 and not 0.0) and the application fails.
Is there a configuration that can be changed for Oracle? I've searched for formatting and locale configurations and they are equal on both servers.
Any help would be appreciated
It turns out there's a parameter called cursor_sharing that was set to FORCE instead of EXACT
select nvl(1,0.0) from DUAL;
The query above returns the following depending on the value of the parameter:
FORCE=NVL(1,0)
EXACT=NVL(1,0.0)

When running a PowerCenter session that uses an Oracle database view as a source the session fails with one of the following errors:
ORA-01843: Not a valid month.
In SqL developer it runs without any issues
Column : Report_date : Data Type : date.
In mapping parameter variable defined as String
Passing report date dynamically using param file &Control table
Select * from ABC
Where report_date=to_char(31-MAR-21,'DD-MON-RR')
--Error: not valid month
Could you please advise on it
You need to put single quotes around infa mapping parameter. Like this -
First calculate Report_Date and put the value in infa param file in correct format. You can use control table too. But you need to create a param file from that.
param file should look like
[folder.workflow.session]
$$Report_Date='21-Oct-2021'
Then in mapping you can call it in source qualifier as -
Select * from ABC Where report_date=to_char('$$Report_Date','DD-MON-RR')
single quote will ensure your data is passed as string.
Now, if youdont want to use param file, you can use control file as a new source and join with the SQL above to get desired result. But first approach is faster.
I need to mask first and last name. Our requirement is to use the first name only. How can I access the FIRST_NM field when masking the LAST_NM?
LAST_NM=substr(FIRST_NM,1,4)||'LAST'
select T.EE_FIRST_NM, T.EE_LAST_NM from MY_TABLE

Expected Result:
LaksFIRST LaksLAST
Looks like REMAP_DATA is available from Oracle 11g on. The issue is the REMAP_DATA parameter takes one column as input and a PL/SQL package/function to process that data; so you wouldn't really be able to figure out what first name goes with what last name. There is a good DataPump REMAP_DATA PDF on a sample package & function would work; but it won't solve your problem.
What you could do, depending on your Oracle version, is define a virtual column named LAST_NAME_MASKED on your MY_TABLE that contains a function to do your substr, and then exclude the LAST_NM column from the DataPump export.
I use in a Java Application JDBC to query the DBMS. The application works correctly with Sql Server but I get this error in DB2 during one insert:
com.ibm.db2.jcc.am.SqlDataException: DB2 SQL Error: SQLCODE=-302, SQLSTATE=22001, SQLERRMC=1, DRIVER=3.63.75
The insert is made using the ResultSet.TYPE_SCROLL_SENSITIVE, ResultSet.CONCUR_UPDATABLE.
My query is a plain select of the table, then I declare my PreparedStatement, passing the parameters and afterwards with the ResultSet I do first the moveToInsertRow() and then the insertRow().
Do you know if there are any problems with this approach using DB2?
As I told you before the same code works correctly with Sql Server.
SQL Code -302 on DB2 means:
THE VALUE OF INPUT VARIABLE OR PARAMETER NUMBER position-number IS INVALID OR TOO LARGE FOR THE TARGET COLUMN OR THE TARGET VALUE
So it seems like you are trying to insert a value into a column which is too large or too short (e.g. Hello World into a varchar(5)). Probably the column has a different length in DB2 and sql-server or you are inserting different values.
Probably too late to add to this thread.. but someone else might find it useful
Got the same SQL Exception when trying to do a SELECT : didn't realize the property value in WHERE clause was exceeding the limit on the corresponding column
SELECT * FROM <schema>.<table_name> WHERE PropertyName = 'value';
value was a VARCHAR type but exceeded the Length limit
Detailed exception does say it clearly that data integrity was violated: org.springframework.dao.DataIntegrityViolationException
So a good idea would be to do a length check on the value(s) that are being set on the properties before firing any queries to the database.
I have the linked server set up in SQL Server 2008. But I could not run any query against the linked server.
I tried to run this simple command but it's not working
SELECT * FROM MYSERVER..ALANH.TEMP_UPDATE1
This is the error I got when I run the above command.
Msg 7399, Level 16, State 1, Line 1
The OLE DB provider "OraOLEDB.Oracle" for linked server "MYSERVER" reported an error. The provider did not give any information about the error.
Msg 7312, Level 16, State 1, Line 1
Invalid use of schema or catalog for OLE DB provider "OraOLEDB.Oracle" for linked server "MYSERVER". A four-part name was supplied, but the provider does not expose the necessary interfaces to use a catalog or schema.
Could anyone help me to connect to the OracleLinkedServer? Thanks very much.
you can be that way too:
**SELECT * FROM OPENQUERY(MYSERVER, 'SELECT * FROM ALANH.TEMP_UPDATE1')**
You can write the query like this:
select * FROM [MYSERVER]..[ALANH].[TEMP_UPDATE1]
Important: In this case, the fully qualified table name must be written in upper case.
You might try the fix from this article.
Also, this could be a problem with naming. From an MS KB article
If you receive these error messages, a table may be missing in the
Oracle schema or you may not have permissions on that table. Verify
that the schema name has been typed by using uppercase. The
alphabetical case of the table and of the columns should be as
specified in the Oracle system tables.
On the Oracle side, a table or a column that is created without double
quotation marks is stored in uppercase. If the table or the column is
enclosed in double quotation marks, the table or the column is stored
as is.
First make sure the tnsping utility works from client server, then use the below string in linked server database source setup
host[:port]/service_name

Try something like this:
SELECT * FROM ALL_TABLES#"SOME.SERVER.NAME";
In this case I'm selecting ALL_TABLES from a linked server called SOME.SERVER.NAME.
Richard's post above was critical.
I am using v12 ODP.NET odbc drivers and had to ensure that "Zero Level Only" was NOT checked and that the names supplied for table and schema were the correct case. All of the schemas and tables I access are uppercase only.
Use the query below to determine what the correct table name is, though you will have to supply the schema name in the correct case for the query to work. Try all uppercase, try all lowercase, try mixed case, or better yet get the actual name from the dba (I've heard that only table/schema names that are "" quoted will be allowed mixed case, otherwise in oracle it's all uppercase.)

I am trying to perform SET operations in Oracle across remote databases.
I am using the MINUS operator.
My query looks something like this.
SELECT NAME FROM localdb MINUS SELECT NAME from remotedb#dblink
This is throwing up a ORA-12704 error. I understand this warrants some kind of conversion or a NLS Setting.
What should I try next?
The two name columns are stored in different characters sets. This could be because of their type definitions, or it could be because the two databases are using different character sets.
You might be able to get around this by explicitly converting the field from the remote database to the character set of the local one. Try this:
SELECT NAME FROM localdb MINUS SELECT TO_CHAR(NAME) from remotedb#dblink
It seams the types of NAME column in those 2 tables are different.
Make sure the NAME column in the remotedb table is exactly the same type as the NAME in localdb table. It is mandatory when you use a MINUS operator.
