Use a variable as a table name with NATIVE SQL
Hi all,
I am trying to execute a SELECT statement in order to fetch data from an external Oracle DB table to SAP with the following instructions:
EXEC SQL.
SELECT cityfrom, cityto
INTO STRUCTURE :wa
FROM spfli
WHERE mandt = :sy-mandt AND
carrid = :p_carrid AND connid = :p_connid
ENDEXEC.
However, I need to indicate the external table name from a variable instead of the solution above. That is, declaring a variable and store the name of the table (e.q. spfli) in it. The resulting ABAP code would be something like:
EXEC SQL.
SELECT cityfrom, cityto
INTO STRUCTURE :wa
FROM <VARIABLE>
WHERE mandt = :sy-mandt AND
carrid = :p_carrid AND connid = :p_connid
ENDEXEC.
Does anybody know if is possible to do that?
If not, is there any other solution?
Thank you in advanceYes, as Suhas said, you could use the ADBC API and his class CL_SQL_CONNECTION to achieve this...
Here is a small example:
PARAMETERS: p_carrid TYPE spfli-carrid,
p_connid TYPE spfli-connid.
DATA:
l_con_ref TYPE REF TO cl_sql_connection,
l_stmt TYPE string,
l_stmt_ref TYPE REF TO cl_sql_statement,
l_dref TYPE REF TO data,
l_res_ref TYPE REF TO cl_sql_result_set,
l_col1 TYPE spfli-carrid,
l_col2 TYPE spfli-connid,
l_wa TYPE spfli.
CONSTANTS:
c_tabname TYPE string VALUE 'SPFLI'.
* Create the connecction object
CREATE OBJECT l_con_ref.
* Create the SQL statement object
CONCATENATE 'select * from' c_tabname 'where carrid = ? and connid = ?'
INTO l_stmt SEPARATED BY space. "#EC NOTEXT
l_stmt_ref = l_con_ref->create_statement( ).
* Bind input variables
GET REFERENCE OF l_col1 INTO l_dref.
l_stmt_ref->set_param( l_dref ).
GET REFERENCE OF l_col2 INTO l_dref.
l_stmt_ref->set_param( l_dref ).
* Set the input value and execute the query
l_col1 = p_carrid.
l_col2 = p_connid.
l_res_ref = l_stmt_ref->execute_query( l_stmt ).
* Set output structure
GET REFERENCE OF l_wa INTO l_dref.
l_res_ref->set_param_struct( l_dref ).
* Show result
WHILE l_res_ref->next( ) > 0.
WRITE: / 'Result:', l_wa-carrid, l_wa-connid.
ENDWHILE.
* Close the result set object
l_res_ref->close( ).
Otherwise you can also use the FM DB_EXECUTE_SQL...

SQL or PL/SQL : dynamically insert table name in a SQL Statement
Hi,
We have a strange requirement - we need to dynamically use the table names in a SQL Query. E.g:
select * from :table_name
The table_name will be chosen from a list. I have tried this in SQL as well as PL SQL - but, I have been unsuccessul so far.
Can you guys please help me solve this puzzle ?
I hope I have explained my quesion clearly - if not, please do let me know if some more details are necessary.
Regards,
RamkyThe following is the anonymous block that im using in a report in HTMLDB. My problem is Line Number 9. The bind variable contains the chosen table name at
the run time.
Variable "qry_stmt" contains the query to be returned, so that result set for that query will be displayed in the report.
If I hard code the table name(rather that passing it through bind variable) in the
qry_stmt string, Im getting the result sets for that query. But if I pass through
bind variable at run time, its still generating the string correctly( im printing
using a print statement at line number 14). But its returing the following report
error
report error:
ORA-01403: no data found
Please advice/help me in this.....

qry_stmt varchar2(1000);

Problem with Dynamic Table Name
Hello all,
I am having trouble using a dynamic table name. I have the following code.....
declare l_cur sys_refcursor;
l_ID int;
l_tableName varchar(30);
BEGIN
open l_cur for
select hkc.ColumnID, mapping from &HKAPPDB_Schema_Name..doctablemapping ddm

UPDATE &HKAPPDB_Schema_Name..IndexedDocument
SET VerbID = (SELECT t.VerbID
FROM (SELECT DocRef, VerbID, DateUpdated
FROM &HKAPPDB_Schema_Name..l_tableName dd - this is where the dynamic table name is used
WHERE dd.VerbID is not NULL))
WHERE HKColumnID = l_ID AND VerbID is NULL;
END loop;
end;
/When I try to execute this i get an error
ORA-00942: table or view does not exist
What am I doing wrong?

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. -

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 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 advanceThere 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>

List Region with Dynamic Table name
Trying to build a page that is similar to Query Builder. On the left side of my page, I need to populate a list of table names from a SQL statement. Once the list is created, will need to perform some addtional actions when user clicks onthe specific row in the list.
What is the best way to create the list (based on SQL) that will allow me to be call some addtional processing when user clicks on the specific row?
Thanks!" this is the problem

Dynamic table names without dynamic sql?
I am trying to figure out a way to use table names as variables without using dynamic sql.
So for instance, I have...
execute immediate 'INSERT INTO '||vTABLE||' VALUES ('test')';
and
execute immediate 'INSERT INTO TABLE1 SELECT * FROM '||vTable;
Is there any other way to do these without the dynamic sql in Oracle 10.2g?I am trying to figure out a way to use table names as variables without using dynamic sql. Well I guess it makes a change from perpetual motion machines or cold fusion.
Are you doing this as a purely academic exercise or do you have something against dynamic SQL?

Dynamic 'from' Clause in Native SQL
Hi All,
While running a select query in ORACLE, we can put the table name in '<i>from</i>' clause at the runtime-Seletion Screen Parameter .
But I am not able to do so in SAP using Native Sql. Does SAP has any restrictions regarding this?
It might be possible that ,by using Embedded SQL (C/C++ precompiler ),we may be able to achive this.
Can any body please throw light on this.
Its Urgent.
Thanks in Advance.

<u>Assuming you can also use Open SQL.</u>
Macroman's suggestion is OK. in Open SQL (this is SQL of ABAP platform) but a query statement can be constituted using some dynamic clauses. Although macro coding has some restrictions it will be less time consuming using it than a dynamic query.
<u>An example SELECT statement with dynamic clauses:</u>
SELECT (fields) FROM (table_name_variable)
INTO <target_fields>
WHERE (conditions_tab) .
