Table variable

Hello,
I declared the following:
TYPE CustRecTable IS TABLE OF Customers_temp%ROWTYPE;
cust_recs CustRecTable;
and then I populate cust_recs from a cursor:
FETCH c_cust BULK COLLECT INTO cust_recs;
Everything works fine so far, I get approx. 500,000 records in cust_recs.
My question is:
How can I insert these records stored in cust_recs (or the cursor?) into a table that has exactly the same column structure?
Can I do this with a single PL/SQL statement or I need to loop? What would be the most efficient method?
I am using Oracle 11g R2.
Thank you,
M.R.

Skip the explicit cursors, loops and table types altogether. Do something like this:
INSERT INTO destination_table
( col1
, col2
, col3
SELECT col1
     , col2
     , col3
FROM   source_table
;Hope that helps. If you need further assistance please post the following information:
1. Oracle version (SELECT * FROM V$VERSION)
2. Sample data in the form of CREATE / INSERT statements.
3. Expected output
4. Explanation of expected output (A.K.A. "business logic")
5. Use \ tags for #2 and #3. See FAQ (Link on top right side) for details.

Open sys_refcursor for select from table variable?

Hi,
I've got a challenge for you! :-)
I've got a procedure that has a lot of logic to determine what data should be loaded into a table variable. Because of various application constraints, i can not create a global temporary table. Instead, i'd like to create a table variable and populate it with stuff as i go through the procedure.
The end result of the procedure is that i must be able to pass the results back as a sys_refcursor. This is a requirement that is beyond my control as well.
Is there a way to make this sort of procedure work?

I would strongly encourage you not to implement something like this. I realize it's tempting when you are working in strict environments where it can take a serious battle to get structures like temporary tables or SQL Types created, but that's really the proper approach to be taking.

Report cannot access pl/sql table variable defined in Package Spec.

Hi,
I've created a package spec called pkg_report with a PL/SQL table variable defined called body_text_table. When I tried to compile the following code under the Before Report trigger:
:desc := pkg_report.body_text_table(1);
Oracle gave me the following error:
Implementation Restriction: 'PKG_REPORT.BODY_TEXT_TABLE': Cannot directly access remote package variable or cursor.
Does anyone have any idea about this error? Thank you for your time at looking at it.
Regards,
John

You cannot directly access the package variable in a database package. The work around is to create a set_variable and get_variable wrapper function in the package body. See Metalink note 105838.1 for more info.
A simple example:
create or replace package my_package as
my_var     number;
function   get_variable return number ;
procedure set_variable (p_value in number) ;
end ;
create or replace package body my_package as
function get_variable return number is
begin
    return my_var;
end ;
procedure set_variable(p_value in number) is
begin
    my_var := p_value ;
end ;
end;

Using a dynamic table variable in a stored procedure

SQL Server can do this where you declare a table variable and insert / modify / delete rows in that table without it ever being actually ON the database.
Can Oracle do this?
I know I can do things like pass in a unique user id, create the table in the procedure with the user ID appended, etc ...
but this procedure is going to be accessed via two modes, a batch job as well as online. The batch job may run this procedure 500 times.
What I'm trying to is figure out a way to return a recordset of errors that occured in the job, simple, 3 lines like so:
LineNumber NUMBER,
Severity VARCHAR(10),
Error_Msg VARCHAR(200)
is there any 3 dimensional way of storing these records when the errors occur, then returning them as a select statement at the end of the procedure?
Thanks,

Why not create a table
CREATE TABLE error_log (
job_id NUMBER,
line_number NUMBER,
severity VARCHAR2(10),
error_msg VARCHAR2(200)
CREATE SEQUENCE seq_error_log_job_id
START WITH 1
INCREMENT BY 1
CACHE 100;In your procedure, you would get a new job_id from the sequence, insert whatever records you want in the error log table using that job_id and then return a REF CURSOR where you select from the error_log table using the job_id.

Query in SQL 2008R2 error Msg 1087, Level 15, State 2, Line 31 Must declare the table variable

Hello Experts,
Can You help me; I get the follwing error in my query
Msg 1087, Level 15, State 2, Line 31
Must declare the table variable "@ASE_SUBART_GROEP".
the @ASE_SUBART_GROEP is a self-defined table in this SQL environment.
Maybe you know the error or the missing part
Thanks in advance, Jos Dielemans

I'm not familiar with SAP Business One unfortunately, so can only be of limited help here. But I'm going to guess that @ASE_SUBART_GROEP is a table variable passed to a stored procedure and is defined and passed down by the application, so you won't
be able to copy-paste this code directly into management studio and get it to work.
You could remove the join to return *all* records. Although the dataset might be very big

Oracle equivalent to SQL Server Table Variables ?

Does Oracle have anything equivalent to SQL Server table variables, that can be used in the JOIN clause of a select statement ?
What I want to do is execute a query to retrieve a two-column result, into some form of temporary storage (a collection ?), and then re-use that common data in many other queries inside a PL/SQL block. I could use temporary tables, but I'd like to avoid having to create new tables in the database, if possible. If I was doing this in SQL Server, I could use a table variable to do this, but is there anything similar in Oracle ? SQL Server example:
use Northwind
DECLARE @myVar TABLE(CustomerID nchar(5), CompanyName nvarchar(40))
INSERT INTO @myVar(CustomerID, CompanyName)
select CustomerID, CompanyName
from Customers
--Join the variable onto a table in the database
SELECT *
FROM @myVar mv join Customers
on mv.CompanyName = Customers.CompanyName
The closest I've found in Oracle is to use CREATE TYPE to create new types in the database, and use TABLE and CAST to convert the collection to a table, as shown below. I can't see anyway without creating new types in the database.
CREATE TYPE IDMap_obj AS Object(OldID number(15), NewID number(15));
CREATE TYPE IDMap_TAB IS TABLE OF IDMap_obj;
DECLARE
v_Count Number(10) := 0;
--Initialize empty collection
SourceIDMap IDMap_TAB := IDMap_TAB();
BEGIN
--Populate our SourceIDMap variable (dummy select statement for now).
FOR cur_row IN (select ID As OldID, ID + 10000000 As NewID From SomeTable) LOOP
SourceIDMap.extend;
SourceIDMap(SourceIDMap.Last) := IDMap_obj(cur_row.OldId, cur_row.NewId);
END LOOP;
--Print out contents of collection
FOR cur_row IN 1 .. SourceIDMap.Count LOOP
DBMS_OUTPUT.put_line(SourceIDMap(cur_row).OldId || ' ' || SourceIDMap(cur_row).NewId);
END LOOP;
--OK, can we now use our collection in a JOIN statement ?
SELECT COUNT(SM.NewID)
INTO v_Count
FROM SomeTable ST JOIN
TABLE(CAST(SourceIDMap As IDMap_TAB)) SM
ON ST.ID = SM.OldID;
DBMS_OUTPUT.put_line(' ' );
DBMS_OUTPUT.put_line('v_Count is ' || v_Count);
END;

Hi, got this from our plsql guys:
The term "table function" is a bit confusing here. In Oracle-speak, it means a function that can be used in the from list of a select statement thus:
select * from Table(My_Table_Function()),..
where...
The function's return type must be a collection that SQL understands. So for the interesting case -- mimicking a function with more than one column -- this would be a nested table of ADTs where both the ADT and the nested table are defined at schema level. PL/SQL -- by virtue of some clever footwork -- allows you to declare the type as a nested table of records where both these types are declared in a package spec. This alternative is generally preferred, especially because the nested table can be of Some_Table%rowtype (or Some_Cursor%rowtype if you prefer).
As I understand it from our man on the ANSI committee, our use terminology follows the standard.
The construct below seems to be a bit different (though there are similarities) because it appears from your code sample that it's usable only within procedural code. And the object from which you select is a variable rather than a function.
So, after that preamble... the answer would be:
No, we don't have any constructs to let you "declare" something that looks like a regular schema-level table as a PL/SQL variable -- and then use (static) SQL on it just as if it were a schema-level table.
But yes, you can use PL/SQL's pipelined table function to achieve much of the same effect.
Look at the attached Table_Function.sql.
It shows that you can populate a collection of records using ordinary PL/SQL code. You can't use SQL for insert, update, or delete on such a collection. I see that SQL Server lets you do
insert into Program_Variable_Table select... from Schema_Level_Table
The PL/SQL equivalent would be
select...
bulk collect into Program_Variable_Collection
from Schema_Level_Table
The attached shows that once you have populated your collection, then you can then query it with regular SQL -- both from inside PL/SQL code and from naked SQL.
and the code is here
CONNECT System/p
-- Drop and re-create "ordinary" user Usr
EXECUTE d.u
CONNECT Usr/p

Using Table Variables MSSQL with xMII 11.5

I was trying an experiment with a query today where instead of creating a temp table in SQL, I used the T-SQL table variable. For a simple example:
DECLARE @ProductTotals TABLE
( ProductID int, Revenue money)
INSERT INTO @ProductTotals (ProductID, Revenue)
SELECT ProductID, SUM(UnitPrice * Quantity)
FROM [Order Details]
GROUP BY ProductID
SELECT *
FROM @ProductTotals
Well, this works fine in SQL Query Analyzer , but not in xMII. I get a message that says "no results returned from this query" So you ask, "why not just use a temp table" Well on the real application, the query can take up to 30 seconds to run, and I have the chance of having multiple users execute the same query in that time, in which my temp table will get stomped on creating an error. So I thought of using table variables as a possible alternative to avoid this.
I have already figured a work around, I put this code into a stored procedure and call that. I could also do a similar workaround using separate queries / BLS. However, I'm curious why xMII wouldn't execute this in the first place, being that it worked fine in Query Analyzer against the exact same database.

Doug,
I tried on my box with the "sqljdbc.jar" from 11.08.2006 (German Dateformat dd.MM.yyyy) and works also.
For my test I had using the following SQL-Statement:
DECLARE @ProductTotals TABLE
( ProductCount int, ProductID int, Revenue money)
INSERT @ProductTotals
SELECT count(O.ProductID) as ProductCount, P.ProductID, SUM(O.UnitPrice * O.Quantity)
FROM [Order Details] O
INNER JOIN Products P
ON O.ProductID = P.ProductID
GROUP BY P.ProductID
SELECT *
FROM @ProductTotals
Did you get a result back in MII only for the SELECT statement
SELECT count(O.ProductID) as ProductCount, P.ProductID, SUM(O.UnitPrice * O.Quantity)
FROM [Order Details] O
INNER JOIN Products P
ON O.ProductID = P.ProductID
GROUP BY P.ProductID
? My opinion is, that your select brings nothing back.

Is it possible to create table variable by copying structure of existing table?

Greetings community,
It’s a newbie question.
I’m still learning T-SQL, and I’m not very familiar with its syntax, so I’m not sure if I’m asking something stupid. I’m creating a “stored function”. I need to create temporary table variable to do some “thinking” in it and spit out a
scalar result. Actually, I have to create about ten similar functions to process ten tables in similar way, so I was searching is it possible to speed it up.
I was wondering is there any way, instead of declaring table variable with list of gazillion columns (and having the possibility to mistype something), to declare table variable so it would inherit structure of existing table.
Thanks for any help.

Temp table variable can not be created on the fly, but temp table can be created.
If you want just the structure, you can use the below.
SELECT Top 0
INTO #temp
FROM
Sales.SalesOrderHeader

Simple command to refresh data of all declared internal tables & variables!

Hi All,
I have declared many internal tables & variables in my program in declaration include.
Is there any Simple command which can refresh data of all declared internal tables & variables!
Instead of clearing & refreshing each i.table & variable i want to use single command to refresh data.
Is this possible!
Thanks in advance.
Thanks,

Whats the difference betweeen passing the table variable and table valued parameter?

Hi Everbody
Can someone one tell me what's the difference between passing a table variable and table valued parameter to a stored procedure or function? Can both be used to pass a table to a stored procedure/function?
Regards
Regards

They are essentially the same. What we call a table variable is a local
variable. A table-valued parameter is an incoming parameter to the
procedure. The only difference is that the parameter is readonly.
When you call a stored procedure, you can pass a table variable as the
actual parameter. Or a table-valued parameter that you pass on.

No need to run this in tempdb
You can run this in your database itself ie database where tables customers, orders etc exist and table variable gets created in tempdb itself
The reason for your error is because it cant find the tables in the tempdb database
So run the query in your own database
Otherwise you need to change it as below if you stiil want this to be executed in tempdb
Declare @customerscount table
(firstname char(30),
totals int,
customerNumber int)
Insert @customerscount
Select
c.firstname,
Count(*) as 'Totals',
o.CustomerNumber
FROM
<yourdbname>.dbo.Customers c join <yourdbname>.dbo.orders o ON
c.customernumber = o.customernumber
Group BY
c.firstname,o.customernumber
assuming dbo is your default schema

Table Variable properties/ uses?

Dear Readers,
I wanted to know how table variable works. Is it like a temp table where we cannot retrieve it after the connection is dropped or is it retrievable?
DECLARE @MyTable TABLE
id INT NOT NULL,
fname VARCHAR(20)
I read somewhere that we can use it in a stored procedure, that means it must be saved somewhere in order to be retrieved?
Thanks for clarifying the concept/issue.
Regards
SQL 75

Nope its like a local variable but of table type
ie its scope is only within the batch where you created it
see this example
declare @t table
v varchar(100)
insert @t
values('uyty1231314'),('qweq2142423uyiy')
--here you will get result

Table variable query optimisation

I have a table variable which (sometimes) needs to contain a couple of thousand rows, this slews the execution plan. This is fixed by DBCC TRACEON(2453) which causes the
rows in the table variable to be estimated properly, this requires sysadmin rights which I am reluctant to grant to other than this stored proc. The proc is excuted by most users with SQL authentication. I've tried with exec as 'NT AUTHORITY\SYSTEM' but that
does not seem to be recognized as I'm using sql authentication. Cant use a temp table as this breaks asp net Linq which is user to wrap the stored procedure.
Suggestions please? Is there another way to tell the proc to count the row in a table variable? Is there a tight scripted way to grant
sysadmin rights to just this stored proc across a number of databases and servers?

Hi Erland, I'm feeling particularly dumb at the moment... I read your article and each step seems clear. so I then tried to put together a script to create a certificate, create a logon, create a (SQL) user, create a proc to run as that user and test. My
dismal attempt is below.
USE master
go
-- Create a test login and test database
CREATE LOGIN testuser WITH PASSWORD = 'CeRT=0=TeST'
CREATE DATABASE certtest
go
-- Move to the test database.
USE certtest
go
-- Create the test user.
CREATE USER testuser
go
-- Create the test table and add some data.
CREATE TABLE testtbl (a int NOT NULL,
                      b int NOT NULL)
INSERT testtbl (a, b) VALUES (47, 11)
go
-- Create the certificate.
CREATE CERTIFICATE TraceOnCert
   ENCRYPTION BY PASSWORD = 'All you need is love'
   WITH SUBJECT = 'Certificate for TraceOnProc',
   START_DATE = '20020101', EXPIRY_DATE = '20200101'
go
-- Create the login
CREATE LOGIN TraceOnLogin WITH PASSWORD = 'CeRT=0=TeST'
GO
--create user link to login
IF NOT EXISTS (SELECT * FROM sys.database_principals WHERE name = N'TraceOnUser')
    CREATE USER TraceOnUser FOR LOGIN TraceOnLogin
--give login sysadmin rights
EXEC master..sp_addsrvrolemember @loginame = N'TraceOnLogin', @rolename = N'sysadmin'
go
GRANT SELECT ON testtbl TO TraceOnUser
go
-- Create two test stored procedures, and grant permission.
CREATE PROCEDURE unsigned_sp AS
   DBCC TRACEON(2453)
   SELECT SYSTEM_USER, USER, name, type, usage FROM sys.user_token
   EXEC ('SELECT a, b FROM testtbl')
   DBCC TRACEOFF(2453)
go
CREATE PROCEDURE TraceOnProc WITH EXECUTE AS 'TraceOnUser' AS
   DBCC TRACEON(2453)
   SELECT SYSTEM_USER, USER, name, type, usage FROM sys.user_token
   EXEC ('SELECT a, b FROM testtbl')
   DBCC TRACEOFF(2453)
   -- EXEC unsigned_sp
go
GRANT EXECUTE ON TraceOnProc TO public
GRANT EXECUTE ON unsigned_sp TO public
go
go
-- Run as the test user, to actually see that this works.
EXECUTE AS USER = 'testuser'
go
-- First run the unsigned procedure. This gives a permission error.
EXEC unsigned_sp
go
-- Then run the signed procedure. Now we get the data back.
EXEC TraceOnProc
go
-- Become ourselves again.
REVERT
go
-- Clean up
USE master
DROP DATABASE certtest
DROP LOGIN testuser
DROP LOGIN TraceOnLogin
