Dynamic SQL select from unknown table until runtime

I need to do a select from a table that is unknown until runtime. Is there any good examples of this. The Store Procedure will take in the table name and return a row.
I am not using inline SQL because there is a lot more complexity involved . What I need to do is understand how to reference this unknown table.
Here is an example of what I have written so far.
PACKAGE pk_LoadNativeDataItems IS
PROCEDURE version;
TYPE RowDataCur IS REF CURSOR;
PROCEDURE pr_LoadNativeDataItems(p_flag IN NUMBER
p_how_many_rows_to_fetch IN NUMBER,
p_row_data OUT RowDataCur);
PROCEDURE pr_LoadNativeDataItems(p_flag IN NUMBER
p_how_many_rows_to_fetch IN NUMBER,
p_table_name IN VARCHAR,
p_row_data OUT RowDataCur) IS
BEGIN
OPEN p_row_data FOR
SELECT * from ||p_table_name||;
END pr_LoadNativeDataItems;
END pk_LoadNativeDataItems;
Thanks for any help

Select from unknown table [ANSWERED]

I have a table that indexes physical table names with IDs as follows:
idxer
idx. tbl_nm
1. employee_tbl
2. cmpny_tbl
I have tried constructing a query that will get data from the table whose index is provided as follows:
SELECT *
FROM (SELECT tbl_nm FROM idxer WHERE idx = 1)
The problem is since the inner select returns a string (as I imagine it) the outer select just returns that string. What I want is the inner select to be evaluated as a table name.
Any help will be appreciated.
Hussam.

To process the results of this query I would recommend the using the INTO clause. Here's an example:
EXECUTE IMMEDIATE 'SELECT * FROM '|| tbl_nm_var
INTO vNewVariable;There are some really great resources available on the internet with examples. A Google search for "oracle dynamic sql" will give enough reading material and examples to keep you busy for a few weeks. :-)
Hope this helps.

I forgot to mention that if your query returns multiple rows, this method will produce a TOO_MANY_ROWS exception. In which case you could use an OPEN <Record variable> FOR 'Dynamic Statement' LOOP construct. The Google search I cited will give you the methods for processing this type of dynamic query.

How to create a dynamic RTF report which creates dynamic columns based on dynamic column selection from a table?

Hi All,
Suppose I have table, whose structure changes frequently on daily basis.
For eg. desc my_table gives you following column name on Day 1
SQL > desc my_table;
Output
Name
Age
Phone
On Day 2, two more columns are added, viz, Address and Salary.
SQL > desc my_table;
Output
Name
Age
Phone
Address
Salary
Now I want to create an Dynnamic RTF report which would fetch data from ALL columns from my_table on daily basis. For that I have defined a concurrent program with XML as output type and have attached a data template/data definition to it which takes in XML as input and gives final output of conc program in EXCEL layout. I am able to do this for constant number of columns, but dont know how to do it when the number of columns to be displayed changes dynamically.
For Day 1 my XML file should be like this.
<?xml version="1.0" encoding="UTF-8"?>
<dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
SELECT Name
,Age
,Phone
FROM my_table
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_my_table" source="Q2">
<element name="Name" value="Name" />
<element name="Age" value="Age" />
<element name="Phone" value="Phone" />
</group>
</dataStructure>
</dataTemplate>
And my Day 1, EXCEL output from RTF template should be like this.
Name     Age     Phone
Swapnill     23     12345
For Day 2 my XML file should be like this. With 2 new columns selected in SELECT clause.
<?xml version="1.0" encoding="UTF-8"?>
<dataTemplate name="XYZ" description="iExpenses Report" Version="1.0">
<dataQuery>
<sqlStatement name="Q2">
<![CDATA[
SELECT Name
,Age
,Phone
,Address
,Salary
FROM my_table
]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_my_table" source="Q2">
<element name="Name" value="Name" />
<element name="Age" value="Age" />
<element name="Phone" value="Phone" />
<element name="Address" value="Address" />
<element name="Salary" value="Salary" />
</group>
</dataStructure>
</dataTemplate>
And my Day 2, EXCEL output from RTF template should be like this.
Name     Age     Phone     Address     Salary
Swapnill     23     12345         Madrid     100000
Now, I dont know below things.
Make the XML dynamic as in on Day 1 there must be 3 columns in the SELECT statement and on Day 2, 5 columns. I want to create one dynamic XML which should not be required to be changed if new columns are added in my_table. I dont know how to create this query and also create their corresponding elements below.
Make the RTF template dyanamic as in Day1 there must 3 columns in EXCEL output and on Day 2, 5 columns. I want to create a Dynamic RTF template which would show all the columns selected in Dynamic XML.I dont know how the RTF will create new XML tags and how it will know where to place it in the report. Means, I can create RTF template on Day 1, by loading XML data for 3 columns and placing 3 XML tags in template. But how will it create and place tags for new columns on Day 2?
Hope, you got my requirement, its a challenging one. Please let me know how I can implement the required solution using RTF dynamically without any manual intervention.
Regards,
Swapnil K.

Hi All,
I am able to fulfil above requirement. Now I am stuck at below point. Need your help!
Is there any way to UPDATE the XML file attached to a Data Definition (XML Publisher > Data Definition) using a standard package or procedure call or may be an API from backend? I am creating an XML dynamically and I want to attach it to its Data Definition programmatically using SQL.
Please let me know if there is any oracle functionality to do this.
If not, please let me know the standard directories on application/database server where the XML files attached to Data Definitions are stored.
For eg, /$APPL_TOP/ar/1.0/sql or something.
Regards,
Swapnil K.

Dynamic parameter selection from infoview not storing the sql password

We are having the problem of dynamic parameter selection from infoview not storing the sql password as it does for the actual report. We are using Crystal Reports XI Release 2 version 11.5.3.438 (Not sure of SP level, asked in separate thread).
To be more specific.
We have created a report that dynamically populates the parameters of the report by pulling the records from the Informix sql database and allowing selection from there.
In the Central Management Console for the report object we have set as follows:
Process - Database:
Use original database logon information from the report - the sql username and pw etc
Use same database logon as when report is run
Process - Parameters
In selecting a default selection there is the option to put in the sql password, however, this does not stick and clears after update.
As such the end result is that every time this report is run from infoview and a user chooses a parameter (there are 5), crystal goes through some timeout for about a minute or so and then requests the sql password, if a user then selects the next parameter, the same timeout and password dialog appears.
We need the crystal report to handle to the sql password for fetching the parameters as well as for the database section of running the report, however, the parameters insists on the end user always putting the password in.
This is 100% replicatable on our system.
Any way that we can fix this?
Will an update fix this issue? If so could you please advise which one?
Thanks

Hi,
I am having the exact same problem. Any help?
And what does "Use same database logon as when report is run" mean? For me that would be that no prompt is needed for getting values in a dynamic parameter...
Regards
Magnus

PL/SQL: ORA-22992: cannot use LOB locators selected from remote tables

Dear ALL,
My O/S is Redhatlinux 5.2 and i had Migrated my Oracle databse to 11g2. But after that while i am retrieving records through dblinks from one of my other Oracle 9.2.0.8 databse it's throwing the error : PL/SQL: ORA-22992: cannot use LOB locators selected from remote tables.* This error i am getting in TOAD as well as SQL Developer.
Can anybody tell me how to fix this error ? Because am not able to get the records.
Also am getting another error during retrieving data from some of my tables after migrating i.e the table which having CLOB data type while am accessing to retrieve the records using select query it's throwing the error :
+(The following error has occurred:+
A query with LOB's requires OCI8 mode, but OCI7 mode is used.)
If anyone having any idea kindly share.
Thanks and Regards
Biswa

Hi,

But while am executing the same procedure in oracle 11g where the Dblink accessing the data from Oracle 9i , there am getting this error.
Kindly tell if u know any resolution.

Select from two tables and insert into a third

I'm trying to do a select from two tables and do an insert into a third table from the two resulting columns.
I have the following....
DECLARE
tempsid number;
temphostid number;
BEGIN
select "DBSID_ID","ID" into tempsid,temphostid from "DBSIDS","SERVERS"
where "HOST_SID" like '%'||"DBSID_NAME"||'%'
and "HOST_NAME" not like 'vio%'
and exists (select "DBSID_NAME" from DBSIDS)
order by "DBSID_NAME";
insert into "DBSID_LOOKUP" ("SIDLOOKUP_ID", "SERVERLOOKUP_ID")
values(tempsid, temphostsid);
END;
run;
I get the error ....
ORA-06550: line 11, column 18:
PL/SQL: ORA-00984: column not allowed here
ORA-06550: line 10, column 1:
PL/SQL: SQL Statement ignored
1. DECLARE
2. tempsid number;
3. temphostid number;

okay ... I tried a different way ...
DECLARE
a number;
b number;
BEGIN
select "DBSID_ID","ID" into a,b from "DBSIDS","SERVERS"
where "HOST_SID" like '%'||"DBSID_NAME"||'%'
and "HOST_NAME" not like 'vio%'
and exists (select "DBSID_NAME" from DBSIDS)
order by "DBSID_NAME";
insert into "DBSID_LOOKUP" (SIDLOOKUP_ID, SERVERLOOKUP_ID) values (a, b);
END;
and now it whines about ...

Selecting from two tables and confirming from them despites they not relate

Please I need a query to select from two tables that are not related to each other.
I also want to confirm data's as in verify wether what the user has entered is in accordance with what is in the tables
Examples
the first table is named "Card" and the second table is named "Student_Details"
Card table contains a column named "Pin_Number".
The Student_Details table contains fields such as Exam_Number, Name, Age, Sex.
The user has to Enter the Pin_Number which has to be confirmed in the Card table and Exam_Number which has to be confirmed in the Student_Details table and verify that both data's are correct.
Please I need the SQL and PL/SQL queries for this problem.
Thanks

Hi,
I think you need two different queries
You can write a procedure like:
create or replace procedure p1 (p_pin_number number, p_exam_number)
is
r_card_row            card%rowtype;
r_student_details     student_details%rowtype;
cursor c1 is
select *
    from card
   where pin_number = p_pin_number;
cursor c2 is
select *
    from student_details
   where exam_number = p_exam_number;
begin
open c1;
    loop
      fetch c1 into r_card_row;
      exit when c1%notfound;
      .... do whatever you want..... and the samething you can do with other cursor
    end loop;
close c1;
end p1;Hope this helps

Selecting from multiple tables, into one internal table

Hi,
What is the best & most efficient method of selecting from multiple table (in my case 6,) into one internal table?
Thanks,
John
Points will be rewarded and all responses will be highly appreciated.

I have simple example :
First one - Join 5 tables
data : f1 type i,
          f2 type i,
          f3 type i.
start-of-selection.
get run time field f1.
write the query 4 or 5 tables join.
get run time field f2.
f3 = f2 - f1 ( Total time).
Second one - joins 3 table and use for all entries
data : f1 type i,
          f2 type i,
          f3 type i.
start-of-selection.
get run time field f1.
write the query 3 tables join and use for all entries
get run time field f2.
f3 = f2 - f1. ( Total time )
Finally you can have time diffrence between the both sql statement.

SSMS is not listing table and views objects though the objects are listed when I execute TSql string "SELECT * FROM sys.Tables"

I have a db, call it xyz.mdb
It suddenly is that SSMS is not listing the table objects nor the Views. SELECT * FROM sys.Tables and SELECT * FROM sys.Views work very fine. But when I click on the tables node, on Objects Explorer, Only the Systems Tables and File Tables folders
show.
Other DBs on same SQL instance do not show same problem. They are all working very fine.
I have backed up and restored this db on other computers and the behaviour is the same. Incidentally right-clicking the db and clicking Properties throws up this error message.

Select from multiple tables without join statement

Hey Gurus,
I would like to make a select from a multiple tables to check if there is any reference to my data. I would like to do it with some elegancy, but I don't know how.
Is in abap sql possible to do it only with the select statement?
Or I was also think about a solution that I should fill some data structure with all of the tables which I want to select from and then just loop that data structure and do the select seperately from all of the tables. I just need to check if it founds some results, so no need to store it. If this solution would be fine what data structure should I use?
Or can tell me what would be the best for this?
My code for select from one table, which I want to make for multiple tables:
SELECT SINGLE id_kniznice FROM zbr_t_autori INTO wa_id
       WHERE id_kniznice EQ ls_extract-zview-id_kniznice.
     IF sy-dbcnt > 0.
       MESSAGE i000(zbr_msgc_lib).
       ls_extract-flags-vim_mark = '*'.
       MODIFY extract FROM ls_extract.
ENDIF.
Thank you for any posts.
Regards,
Robert

And there we go again...
Read this topic:
For All Entries is NOT better than INNER JOIN in most cases
And this one:
inner join vs for all entries
Also that one:
Re: LOOP AT vs INNER JOIN
JOINs are really better than for all entries in most cases. Problem is people tend to ignore basic things like using pks or indexes while making them.

but this did not work.

(1)From this output how I can know that how often archivelog is getting genarated what should be the actual interval of genaration.
(2)How can I know the size of redolog group & it's member's size.
(3)How can I determine that these sizes are perfect with my DB(Because of performance issue).

You can use this query to see the gap in time between creating archive logs which should give an indication of log switches,
set linesize 1000
select name "archive log",
       ftime "first time",
       trunc(ftime- pftime) || ' days ' ||
       trunc( mod( (ftime-pftime)*24, 24 ) ) || ' hours ' ||
       trunc( mod( (ftime-pftime)*24*60, 60 ) ) || ' mins ' ||
       trunc( mod( (ftime-pftime)*24*60*60, 60 ) ) ||' secs ' "Time Gap"
from
select name,
        first_time ftime,
        lag(first_time,1) over (order by first_time ) pftime
from v$archived_log order by first_time
/The size of the log files are in V$LOG, groups and members in V$LOGFILE.
You can extract the log switch information from the alert log.
(there is also the DBA_HIST_LOG table).

Sql text from statspack tables

Hi,
How can I get sql information from statspack tables stats$sql_text, stats$sql_summarry..?
I tried writting sql but not able to get the proper results, please help.
select b.hash_value hash_value, a.snap_time snap_time, b.module module, b.fetches fetches, b.executions executions,
b.rows_processed rows_processed, b.cpu_time cpu_time, b.elapsed_time elapsed_time from stats$snapshot a,stats$sql_summary b
where a.snap_id=b.snap_id and b.snap_id between 1 and 13
and I need to get the complete stats$sql_text.sql_text in the same query without using any procedure or function..
version is 9.2.0.8.
Thanks
clin

I'd also do this the way MOD says.
But if you are feeling adventurous, you could explore cascading delete. You can specify a primary key with "on delete cascade", which makes referred-to records automatically delete. Google for oracle delete cascade or search your Oracle docs.
I wouldn't do cascading deletes myself, though. For one, I've ran into enough trouble with many "smart" db features when trying to do db administration.
