PL/SQL using dynamic table names

I want to create a procedure in which i want to pass a parameter which after concatenation with a string gives me a variable which is the tablename in my SELECT query in the procedure.
How to do it?

See here for an example using ref cursor.

Dynamic SQL substituting dynamic table name with slct statement having date

Hello,
I just wanted some help with the following PL block. My problem is whenever I try to run this block it ask for invoking values for 2 substitute variables, though no substitute variables present in the code. Please find the code below:
Declare
cursor C_1 is
select unique table_name from gsi_daily_count;
table_names varchar2(240);
Begin
Open C_1;
Loop
Fetch C_1 into table_names;
EXIT WHEN C_1%NOTFOUND;
EXECUTE IMMEDIATE' select last_extract_date,
to_char(min(greatest(nvl(last_update_date,'||01-Jan-10||'),nvl(program_update_date,'||01-Jan-10||'))),'||DD-MON-YY HH24:MI:SS||') mi,
to_char(max(greatest(nvl(last_update_date,'||01-Jan-10||'),nvl(program_update_date,'||01-Jan-10||'))),'||DD-MON-YY HH24:MI:SS||') ma
from' || table_names ||'
group by last_extract_date
order by last_extract_date desc';
End Loop;
Close C_1;
COMMIT;
End;
Please help.
Thanks in advance.

You cannot specify your dates the way you have since they are being intepreted as bind variables:
Try this:
Declare
cursor C_1 is
    select unique table_name
    from gsi_daily_count;
    table_names varchar2(240);
Begin
Open C_1;
Loop
    Fetch C_1 into table_names;

but thats what you get when a company throws you in at the deep end with a ridiculous time constraint to migrate a whole MSSQL DB.Migrating SQL-Server to Oracle is not a simple thing. A lot of best practices in SQL-Server are absolutely worse practices in Oracle - they are that different. Simple example is lock escalation - an issue in SQL-Server. In Oracle, the concept of a lock being escalated into a page lock simply does not exist.
In terms of getting the migration done as quickly and painlessly as possible I try to reuse all the logic as it appears in the MSSQL code - in this case it was using dynamic table names. I do not doubt that i am probably shooting myself in the foot in the long run.....As long as you do not splatter too much blood on us here.. not a problem :D
Seriously though - just keep in mind that what works in SQL-Server may not work as well (or even at all) in Oracle. So do not hesitate to refactor (from design to code to SQL) mercilessly when you think it is warranted.

Dynamic table name from Arguments in cfquery /

I'm trying to use dynamic table names in a cfc but seem to
have hit upon a wall as my calling methods from flash keep hitting
my _error methods - Code attached to show what I'm trying to
achieve; if anyone can give me some pointers it would be a great
help. I've seen numerous by using the Form with the arguments but
this is coming into a gateway used by a flash component and doesn't
work no matter how much I fiddle the code.
Thanks in advance

There was a time when I needed a dynamic query such as this.
BUT, it is very dangerous, which is why I took a few steps to make
it more secure.
1. Always use cfqueryparam and strict datatyping
2. Use listFindNoCase for known table names in the database
e.g
<cfset variables.tableNames =
"items,products,categories,blog" />
<cfif
listContainsNoCase(variables.tableNames,lCase(trim(arguments.tableName)),",")>
query here
<cfelse>
Error: Unknown table requested
</cfif>

(Urgent) Dynamic Table Name

Hi Fellows,
Can I use dynamic table name in a loop? I have a problem that I want to use variable table in a cursor for example
procedure check_rows as
cursor c1 is
select view_name
from user_views;
v_count number;
v_view_name varchar2(35);
begin
for i in c1 loop
select count(*)
into v_count
from i.view_name;
if v_count = 0 THEN
dbms_output.put_line ('The View '| |i.view_name| |' has no rows');
end if;
end loop;
end;
but i receive a message
i.view_name must a name of a table to which the user has access.
Can anybody solve my problem.

Dynamic table name in select statment

hai,
Please help me....
oracle 9i i am using.
i have four tables abc_121,
abc_122,
abc_123,
abc_124.
i want to pick records from a table.table name should be prepared dynamically.
i.e., i want to pick records from a quarter table of this year.(ex: abc_124). using sql statement only.
i have tried..but i couldn't...... pls help me...

i.e., i want to pick records from a quarter table of this year.(ex: abc_124). using sql statement only.Create a partition view. E.g.
create or replace view abc as
select * from abc_121
union all
select * from abc_122
union all
...For the partition view approach to correctly work (doing "partition pruning"), you need to have a constraint on the column that identifies that partition.
In other words, you cannot use the table name as an attribute to identifies its data content. Foe example, you can have tables YEAR2001_Q1 and YEAR2001_Q2. However, the year and quarter also need to be in the table itself - e.g. columns YEAR and QUARTER.
For table YEAR2001_Q1, the YEAR column needs to have a check constraint that ensures it is always 2001. And a check constraint for column QUARTER to ensure that it is always 1.
If these conditions are met, then a select from the partition view using +"where YEAR=2001 and QUARTER=2"+ will result in only table YEAR2001_Q2 to be used and not other tables like YEAR2001_Q1.

Passing dynamic table name in ADO. net destination

I am new to SSIS and I have a requirement where i need to pass dynamic table name in ADO .net destination .
My package contains an "Execute Sql task" in the control flow which computes the destination table name to be provided at run time and stores it in a variable expression
"@[User::Table_name]"(which has a scope of full package).
Now, the problem I'm facing right now is that , I am unable to use this variable expression in the ADO .Net Destination .
I need to pass this variable expression as the table name in ado .net destination.
But, whenever I use this variable in place as the table name I keep on getting this error and my package fails:-
[ADO NET Destination [403]] Error: The Table or View name is not expected. \n\t If you are quoting the table name, please use the prefix " and the suffix " of your selected data provider for quotation. \n\t If you are using multipart name,
please use at most three parts for the table name.
Although ,I am able to run my package when i am providing the existing(static) table name.So there is nothing wrong with the package.
Tried a lot of things still not working..Please help...

I am having the result stored in the variable expression . I just need a way to be able to use it as the Destination table in ADO .net Destination.
I am not sure if this will work for you, but I am able to store the table name in variable and use it dynamically (via data flow task expression property ) as shown.
Thanks, hsbal
Hi Adeep,
Based on my further research, just as hsbal said, we can set a variable as ADO.NET Destination table via Expressions property in Data Flow Task.
If there are any other questions, please feel free to ask.
Thanks,

Dynamic table name - error

After run (or test) of procedure
create or replace procedure tmp_select_dymanic

ACount OUT NUMBER
) as
begin
EXECUTE IMMEDIATE 'BEGIN SELECT count(*) INTO :Count FROM :InTable END;'
USING ACount, AInTable;
end tmp_select_dymanic;
error message: invalid table name.
I know the table exists and contains data. I can make SELECT in SQL (not dynamic).
What a reason for error? May be privileges in database? But i make SELECT on my own table?
How can i set dynamic table name in other way?
My Oracle Version 10g.

What you are asking can be done by REF_CURSOR;
look this example and try your self the rest:
CREATE OR REPLACE PROCEDURE insert_to_table_dinamic (
   table1   IN   VARCHAR2,
   table2   IN   VARCHAR2
AS
   rc         sys_refcursor;

Import Data using Full Table Name

Is there a way to run the import data wizard so when pulling data from a csv it generates an insert statement not only using the table name but using the Oracle Schema name -- ie fully qualified table name?

Hi Nilanjan,
I need help ASAP.
About this dump-load task, how does it works? Because I was checking out a package called Import SQL and this one only imports data from a table, however this table has to be allocated within the database that is being used, and I right? Are these 2 related somehow?
Does this task order BPC to find data from a SQL Table (allocated in a different server, different instance for SQL) and import it to SQL Fac2 table?
Can you help me with a simple explanation what do I need to do to run this task? The page help.sap.com talks shows a section within DumpLoad Task Usage which is called Importing Into SQL Server...
* Processing the Application using DumpLoad -
Importing into SQL
You can use DumpLoad to process the application as a standalone procedure, or with data import, export, or clear.
Prerequisites
The DumpLoad task (OsoftTaskDumpLoad2008.dll) is registered with Microsoft SSIS. See Registering Custom Tasks.
Procedure
1.Open a package or create a new package in Microsoft SSIS on the Planning and Consolidation server. i already did this for the DumpLoad task ... should I do this for the Import SQL task also ?
2.Select the task and add it to the package. WHAT DOES SELECT THE TASK MEAN?
3.Open the task, and choose Data Management None .
4.Enter the application set, application, and user ID.
Im getting confused, can you please provide more details about the whole procedure. Thanx in advance

We are having a very peculiar problem where the gateway service works inconsistently for the same input data.
i.e If I execute the same service n number of times, I get the results successfully for say n-3 times but the other 3 times I get a "RFC Error :Error while executing Database procedure"
There is no change in the input data or DB table data during all the executions.
Running the stored procedure stand alone in HANA studio works all the time.
We tried executing the AMDP from SE24 and the same behavior occurred.
When trouble shooting we found that the exception occurs inside the AMDP when the call db procedure statement is executed.
Could you please advise what could be the possible reason for this any tuning parameter/unavailability of db connections?
Or could you please suggest some other troubleshooting mechanism by which we can zero in on the cause?
When I go in the debug mode I can see the exact error as
cannot use duplicate table name: [288] SAPXXX.ZCL_PLAN_MAINTENANCE=>GET_COMP_TYPE#stub#20140905055908: line 15 col 3 (at pos 492): cannot use duplicate table name exception:
where ZCL_PLAN_MAINTENANCE=>GET_COMP_TYPE is the AMDP class and method. SAPXXXis the schema.
