How to resolve Information - Not a valid month error? - informatica-powercenter

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.

Oracle SQLLDR - Load Record with Invalid Date, Replace Invalid Date with Null

There are records in my source text file with invalid date values. The invalid date values are inconsistent in format due to manual entry. I still want to load all of these records, but I want to replace the invalid date value with a null.
Please let me know if/how this is possible via SQLLDR control file commands. I want to avoid creating any custom functions. Something simple that generally refers to errors/exceptions and that works (unlike the below) is ideal:
DATE "MM/DD/YYYY" NULLIF (FROM_DOS=EXCEPTION)
Thanks!
As far as I can tell, that won't go in a single pass. I'd suggest you to try a relatively simple approach:
load the original data "as is"
rows with invalid dates won't be loaded, but will end in the .BAD file
then modify the control file:
source will now be the .BAD file
load NULL into the date column (FILLER might help)
Alternatively, you might use the source file as an external table and write (PL/)SQL against it to load data into the target table. It allows you to actually code whatever you want, but - as you said you don't want to create a custom function (which would decide whether the input data is - or is not - a valid DATE value), I presume you'd rather skip that option.

How do I use a parameter within BI Publisher to update the table name I am querying in an Oracle Data set

I am trying to create a BI Publisher data model which runs the Oracle query below -
SELECT *
FROM audit_YYYYMM
(this should be the YYYYMM of the current date)
How do I setup a parameter default value within the datamodel to grab the YYYYMM from the SYSDATE?
How do I append this parameter within the data set SQL Query?
I tried SELECT * FROM audit_:Month_YYYYMM
(where I had a string parameter called Month_YYYMM)
This did not work.
You are going to have to use something like EXECUTE_IMMEDIATE. And you may have to make a separate PL/SQL package to launch rather than use the built in data definition stuff.

Unable to pass parameters with periods in Oracle APEX / REST

Using Oracle APEX 5.0.4, with Oracle 12c. I am trying to write a REST service in Oracle APEX. I have a SQL statement...
select * from <my_table> where company_name = 'GOOGLE INC.'
When run from a straight SQL prompt, this runs and returns data. I have tried to implement this in a REST service, specifically using a URI template. I am using a bind variable, so my query now looks like.
select * from <my_table> where company_name = :ACCT_NAME;
Both the space and the period in my company name are causing me problems, returning no rows. If my BIND VARIABLE is a single word, then no problems. I found UTL_URL.UNESCAPE, and have tried to use that. This seems to solve the problem of having a space, but does not fix issue when the company name contains a period.
I rewrote my SQL Statement to
select * from <my_table> where company_name = UTL_URL.UNESCAPE(:ACCT_NAME);
The query will work if the BIND VARIABLE (aka company name) is multiple words, but NOT containing a period. For example, I can look up 'GOOGLE INC' by setting my bind variable = 'GOOGLE%20INC' . I need to be able to look up 'GOOGLE INC.' [notice the period at the end of INC] so I set my bind variable = 'GOOGLE%20INC%2E' and I consistently get 'BAD REQUEST'. It appears that the URI template is not valid.
If I pass this in via a straight SQL statement (aka OUTSIDE of the REST service), my data is found...
select * from <my_table> where company_name = UTL_URL.UNESCAPE('GOOGLE%20INC%2E');
There is something unique about the PERIOD character... Any ideas?

Oracle generated column aliases different on two DB's

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)

How to resolve SQL query parameters mapping issues while using Oracle OLE DB provider?

When trying to enter a SQL query with parameters using the Oracle OLE DB provider I get the following error:
Parameters cannot be extracted from the SQL command. The provider might not help to parse parameter information from the command. In that case, use the "SQL command from variable" access mode, in which the entire SQL command is stored in a variable.
ADDITIONAL INFORMATION:
Provider cannot derive parameter information and SetParameterInfo has not been called. (Microsoft OLE DB Provider for Oracle)
I have tried following the suggestion here but don't quite understand what is required:Parameterized queries against Oracle
Any ideas?
To expand on the link given in the question:
Create a package variable
Double click on the package variable name. (This allows you to access the properties of the variable)
Set the property 'EvaluateAsExpression' to true
Enter the query in the expression builder.
Set the OLE DB source query to SQL Command from Variable
The expression builder can dynamically create expressions using variable to create 'parametised queries'.
So the following 'normal' query:
select * from book where book.BOOK_ID = ?
Can be written in the expression builder as:
"select * from book where book.BOOK_ID = " + #[User::BookID]
You can then do null handling and data conversion using the expression builder.
If You use Data Flow Task and use OLE DB Source, and you need parameterize your Query :
Create Variable to save "Full" of Query statement : Right Click on blank area outside the package - and Click Variables :
Click Add Variables on Variables Window :
Make the name is SQL_DTFLOW_FULL or something that can you understand easily. The variable data type is STRING
Create Variable(s) to save your parameter(s).
i.e, the full of Query stamements is :
SELECT * FROM BOOK WHERE BOOK_ID = #BookID --#BookID is SQL Parameter
at the sample above, I have just one parameter : #BookID, so I need to create one variable to save my parameter. Add more variables depends on your Queries.
Give it name SQL_DTFLOW_BOOKID
The variable data type is STRING
So, you need make your SSIS neat, and the variables is sorted in understandable parts.
Try to make the variable name is SQL_{TASK NAME}_{VariableName}
Make Expression for SQL_DTFLOW_FULL variable, click on number 1, and start fill number 2. Make Your SQL Statements to be a correct SQL Statement using string block. String block usually using "Double Quote" at the beginning and the end. Concat the variables with the string block.
Click evaluate Expression, to showing result, to make sure your query is correct, copy-paste the Query result at SSMS.
Make sure by yourself that the variables is free from SQL Injection using your own logic. (Use your developer instinct)
Open the Data Flow Task, open the OLE DB Source Editor by double click the item.
Select the Data Access Mode : SQL Command From Variable
Select the Variable Name : SQL_DTFLOW_FULL
Click Preview to make sure it works.
That is all, my way to prevent this SSIS failure case. Since I use this way, I never got that problem, you know, SSIS something is weird.
To change the variable value, set it before Data Flow Task, the SQL Result of SQL_DTFLOW_FULL variable will changed every you change your variable value.
In my case the issue was that i had comments within the sql in the normal form of /* */ and i also had column aliases as "Column name" instead of [Column Name].
Once i removed them it works.
Also try to have your parameter ? statement within the WHERE clause and not within the JOINS, that was part of the issue too.
