Two temp tables in a Stored Procedure

Hi guys,
Is it feasable to use two stored procedures and form joins between them within a single stored procedure. I am trying a workaround for cursors in SYBASE.
Thanks,
Developer

This Create a temporary table in stored proc is a long and occasionally fractious discussion of the differences between temp tables in Oracle and MS SQL Server (and hence Sybase). You may wish to review it, or at least the links to the documentation.
Alternatively, expalin what it is the sybase code is doing and we will tell the best way to implement it in Oracle.
Cheers, APC

A temp table in a stored procedure , set a value to varchar(MAX)

Hi ,,
In stored procedure there is a temp table and set a value to varchar(MAX) . What exactly is the different between setting it to varchar (MAX) instead of varchar(n)
Thank You

Temp Table within an Stored Procedure

I'm pretty new to Oracle, but I have been developing in MS SQL for about 15. So I'm still getting use to the syntax and features within Oracle.
I'm trying to create a stored procedure that has two temporary tables within it, and then queries both them tables and inserts the results into a table.
I created the script but when they try to run in on the server it wont run. Can you guys tell me what I'm doing wrong?
CREATE OR REPLACE PROCEDURE UpdateFIDB_SP IS BEGIN CREATE GLOBAL TEMPORARY TABLE myAAAA AS (SELECT AAAA.1111, AAAA.2222, BBBB.3333_EXT, CCCC.4444, DDDD.5555, DDDD.6666, DDDD.7777, DDDD.8888, AAAA.9999, EEEE.1010, EEEE.1A1A, EEEE.1B1B, FFFF.3333_LO, FFFF.1C1C, AAAA.1D1D FROM mySchema.FFFF_07 FFFF RIGHT OUTER JOIN mySchema.EEEE EEEE ON FFFF.9999 = EEEE.1B1B RIGHT OUTER JOIN ( mySchema.DDDD DDDD RIGHT OUTER JOIN mySchema.AAAA AAAA ON DDDD.1D1D = AAAA.1D1D ) ON EEEE.PSPNR = AAAA.9999 LEFT OUTER JOIN mySchema.CCCC CCCC ON AAAA.3333 = CCCC.3333 LEFT OUTER JOIN mySchema.BBBB BBBB ON AAAA.3333 = BBBB.3333_INT GROUP BY AAAA.1D1D, AAAA.1111, AAAA.2222, BBBB.3333_EXT, CCCC.4444, DDDD.5555, DDDD.6666, DDDD.7777, DDDD.8888, AAAA.9999, EEEE.1010, EEEE.1A1A, EEEE.1B1B, FFFF.3333_LO, FFFF.1C1C ON COMMIT DELETE ROWS); CREATE GLOBAL TEMPORARY TABLE myGGGG AS (SELECT GGGG.1E1E, GGGG.1F1F, GGGG.1G1G, GGGG.1H1H, GGGG.1I1I, GGGG.1J1J, GGGG.1K1K, GGGG.R1D1D, GGGG.1L1L, GGGG.1M1M, GGGG.1N1N, GGGG.1O1O, GGGG.1P1P, GGGG.1Q1Q, HHHH.1R1R, IIII.1S1S, IIII.1T1T, IIII.1U1U, IIII.1V1V FROM mySchema.IIII IIII INNER JOIN mySchema.GGGG GGGG ON IIII.1K1K = GGGG.1K1K LEFT OUTER JOIN mySchema.HHHH HHHH ON GGGG.1L1L = HHHH.1W1W WHERE ( GGGG.1M1M IN ('20', '30') ) AND ( TO_DATE(IIII.1V1V, 'dd-mon-yyyy') = TO_DATE('31-DEC-9999','dd-mon-yyyy') ) AND ( TO_DATE(GGGG.1N1N, 'dd-mon-yyyy') >= TO_DATE('01-Jan-2011','dd-mon-yyyy') ) ON COMMIT DELETE ROWS); TRUNCATE TABLE FIDB; INSERT INTO FIDB (1111, 2222, 3333_EXT, 4444, 5555, 6666, 7777, 8888, 9999, 1010, 1A1A, 1B1B,3333_LO, 1C1C, 1D1D, 1E1E, 1F1F, 1G1G, 1H1H, 1I1I, 1J1J, 1K1K, R1D1D, 1L1L, 1M1M, 1N1N, 1O1O, 1P1P, 1Q1Q, 1R1R, 1S1S, 1T1T, 1U1U, 1V1V) SELECT myAAAA.1111, myAAAA.2222, myAAAA.3333_EXT, myAAAA.4444, myAAAA.5555, myAAAA.6666, myAAAA.7777, myAAAA.8888, myAAAA.9999, myAAAA.1010, myAAAA.1A1A, myAAAA.1B1B, myAAAA.3333_LO, myAAAA.1C1C, myAAAA.1D1D, myGGGG.1E1E, myGGGG.1F1F, myGGGG.1G1G, myGGGG.1H1H, myGGGG.1I1I, myGGGG.1J1J, myGGGG.1K1K, myGGGG.R1D1D, myGGGG.1L1L, myGGGG.1M1M, myGGGG.1N1N, myGGGG.1O1O, myGGGG.1P1P, myGGGG.1Q1Q, myGGGG.1R1R, myGGGG.1S1S, myGGGG.1T1T, myGGGG.1U1U, myGGGG.1V1V FROM myGGGG INNER JOIN myAAAA ON myGGGG.R1D1D = myAAAA.1D1D ORDER BY myGGGG.R1D1D; COMMIT; END;

Some people still sound mad at me because I have two queries and use temp tables
Because in Oracle, unlike in sql server, you generally do not NEED temp tables at all.
One of the biggest mistakes new Oracle developers make is to use PL/SQL when SQL will do the job just fine. Using PL/SQL when it isn't needed generally makes the code slower, less scalable and harder to maintain.
One of the biggest mistakes sql server developers make when they use Oracle is to use temp table when they aren't needed. They try to write code in Oracle exactly the same way they wrote it in sql server. That creates temp tables that aren't needed, makes their code perform horribly and also makes it less scalable and harder to maintain.
Oracle works differently and generally doesn't need ANY temp tables. You need to learn about how Oracle handles transactions and read consistency and how writers do NOT block readers and vice versa.
Create a new thread and post FORMATTED code that shows the PROBLEM you are trying to solve and we can show you the proper way to solve it. That 'proper way' will likely NOT include any need for or use of temp tables.

MySQL temp tables or Calling Stored procedures in CS4

I need to filter a result set by username before performing a LEFT JOIN and including OR IS NULL rows. The SQL works from from the mysqli client, by either creating a temp table using "create temporary table temp_appts select * from..." Or by creating a stored procedure which contains the same "create temp table" statement, then running my LEFT JOIN statement against the temp table.
I have tried both in CS4, it accepts the code in "code view" without errors but the page in a browser loads as a blank or a 500 error in IE. In my experience, this is caused by exiting before reaching the html header.
Is it possible to do either in CS4? Below is the code I am using.
$varU_temp_appts = "-1";
if (isset(<?php $_SESSION['MM_Username'])){
$varU_temp_appts =$_SESSION['MM_Username'];
mysql_select_db($database_ess, $ess);
$query_temp_appts = sprintf("CREATE TEMPORARY TABLE temp_appts SELECT * FROM appts WHERE username=%s", /GetSQLValueString($varU_temp_appts, "text"));
$temp_appts = mysql_query($query_temp_appts, $ess) or die(mysql_error());
$row_temp_appts = mysql_fetch_assoc($temp_appts);
$totalRows_temp_appts = mysql_num_rows($temp_appts);
mysql_select_db($database_ess, $ess);
$query_todays_appts = "SELECT * FROM appt_tm LEFT JOIN (temp_appts) ON appt_tm.appt_time=temp_appts.appt_hr WHERE(appt_date=CURDATE() OR appt_date IS NULL)";
$todays_appts = mysql_query($query_todays_appts, $ess) or die(mysql_error());
$row_todays_appts = mysql_fetch_assoc($todays_appts);
$totalRows_todays_appts = mysql_num_rows($todays_appts);
Any help is appreciated!

Writing to a temp table in a stored procedure with dynamic sql

Hi
I am writing into a temp table with dynamic sql:
select coloum_name into #temp_table from
+
@DestinationDBName+'.information_schema.tables
and then I am trying to use #temp_table in the procedure:
select coloum_name into #anotherTable from #temp_table
but I am getting an error that #temp_table is not recognized.
Can a temp table not be used in dynamic sql ?
How can I overcome this problem ?

Temp Table Can used easily in Dynamic Query in SQL Server and here is small Exmaple you can check it and do like it
CREATE PROC test
AS
BEGIN
CREATE TABLE #T1
(ID int , NAME Nvarchar(50))
CREATE TABLE #T2
(ID int , NAME Nvarchar(50))
DECLARE @SQL NVARCHAR(MAX)='Insert into #T1
SELECT database_id , Name FROM Sys.Databases
Insert into #T2 Select ID , Name from #T1 '
EXEC SP_ExecuteSQL @SQL
SELECT * FROM #T2
DROP TABLE #T1
DROP TABLE #T2
END
Exec Test

Temp table scope within stored procedures

Hi,
I want to build a main sproc that will contain a temp table with policy records. I then want to call a 2nd sproc from the main sproc, but i want to be able to use the temp table that was created in the main sproc within the 2nd sproc.
Is this possible? If so, is it better to use #temptable, ##temptable, or temptable variable?
thanks
Scott

I then want to call a 2nd sproc from the main sproc, but i want to be able to use the temp table that was created in the main sproc within the 2nd sproc.
Yes this is possible, you can use that temp table in other proc. I would go with #temptable.
Sample:
use master
go
create proc subproc
as
begin
--temp table
select 1 temptable into #t
select * from #t
--table variable
declare @t table (tablevariable int)
insert into @t values (1)
select * from @t
end
go
create proc mainproc
as
begin
exec subproc
end
go
--call the procedure
exec mainproc
--drop proc subproc
--drop proc mainproc

Returning a table from a stored procedure

hi, i need to return a table from a stored procedure and show it, and come to this, but a don't know hoy to run it, so i don't know if it is right, can anyone help me?
uTable out objects_uptime%rowtype
as
begin
select * into uTable from objects_uptime;
end;

well, i finally discovered how to do the trick
this is the code for the function:
CREATE OR REPLACE FUNCTION FN_GET_RECORDS RETURN UPTIME PIPELINED IS
CURSOR cUptime is select * from objects_uptime;
p refcur.refcur_t;
temp p%ROWTYPE;
temp2 OUPTIME := OUPTIME(null, null, null, null, null, null, null, null, null);
BEGIN
OPEN cUptime;
LOOP
FETCH cUptime into temp;
temp2.OBJ_NAME := temp.OBJ_NAME;
temp2.IP := temp.IP;
temp2.STATUS := temp.STATUS;
temp2.DOE := temp.DOE;
temp2.ENABLED := temp.ENABLED;
temp2.COMMENT00000 := temp.COMMENT00000;
temp2.USERID := temp.USERID;
temp2.OBJECTID := temp.OBJECTID;
temp2.MNTID := temp.MNTID;
pipe row(temp2);
EXIT WHEN cUptime%NOTFOUND;
END LOOP;
RETURN;
END FN_GET_RECORDS;
and this for the auxiliar package, object and table:
CREATE OR REPLACE PACKAGE REFCUR
as
TYPE refcur_t IS REF CURSOR RETURN objects_uptime%ROWTYPE;
end REFCUR;
CREATE OR REPLACE TYPE OUPTIME AS OBJECT ( "OBJ_NAME"
VARCHAR2(255), "IP" VARCHAR2(20), "STATUS" VARCHAR2(10),
"DOE" DATE, "ENABLED" NUMBER(10, 1), "COMMENT00000"
VARCHAR2(1000), "USERID" VARCHAR2(50), "OBJECTID" NUMBER(10,
1), "MNTID" NUMBER(10, 1) )
CREATE TYPE TUPTIME AS
TABLE OF OUPTIME
i call it this way:
select * from table(FN_GET_RECORDS ())
if anyone knows how to do the same in a shorter manner, tell me please.
thanks to everybody for the help.

Global Temp Tables in a Stored Proc

Hi All,
I'm trying to create a procedure that creates some tables and then creates global temporoay tables. This runs fine in a scrupt but when I place it in a proc, it fails with the following error
Error(172,10): PLS-00103: Encountered the symbol "TABLE" when expecting one of the following: := . ( @ % ;
I'm using the code below to create the global temp tables but I don't think you can do this in a procedure????
TRUNCATE TABLE TMP_table;
DROP TABLE TMP_table;
CREATE GLOBAL TEMPORARY TMP_table
ON COMMIT PRESERVE ROWS
AS SELECT
Thanks for any help given

Why are you trying to create a temporary table in a stored procedure?
In Oracle, you almost certainly want to create the temporary table once at compile time just like any other table. The difference is that the data in a temporary table is local to the session.
If you really wanted to execute DDL in a stored procedure, you'd need to use dynamic SQL. But it's almost always a bad idea to do so.

How can i create a Global Temporary Table inside a Stored Procedure....

Hi...
I need to create a Global Temporary Table inside a Stored
Procedure....
I have no idea how to do that....
Please....if u can send me a sample, send to me....
Thanks a lot

To create a global temporary table inside a stored procedure,
the minimal syntax would be:
CREATE OR REPLACE PROCEDURE procedure_name
AS
BEGIN
EXECUTE IMMEDIATE 'CREATE GLOBAL TEMPORARY TABLE table_name'
|| '(column_name NUMBER)';
END procedure_name;
As Todd stated, it would probably be better to create the global
temporary table outside of the procedure:
SQL> CREATE GLOBAL TEMPORARY TABLE table_name
2 (column_name NUMBER);
Table created.
You can also specify things like ON COMMIT PRESERVE ROWS or ON
COMMIT DELETE ROWS.
It may be that there is something else, like a PL/SQL table of
records or a cursor, that would suit your needs better. It is
difficult to guess without knowing what you want to do with it.

Procedure....
I have no idea how to do that....
Please....if u can send me a sample, send to me....
Thanks a lot

there are many ways to do this..
one u can use dbms_utility package to run ddl statements like
for ex:
declare
t varchar2(200):='order_no';
v number;
begin
--dbms_utility.exec_ddl_statement('select '||t||' into '||v||'
from
--ordermaster where rownum=1');
dbms_utility.exec_ddl_statement('create table cvt(t number)');
dbms_output.put_line(v);
end;
but the actual method(recommended) involves a bit coding using
dbms_sql package you will find examples on technet or metalink
to use this package..
I hope this helps

Joining java array with SQL table in a stored procedure

Hey,
I am calling a pl/sql stored procedure from a java program passing two arrays (employees) and (departments) as parameters to the procedure. Within the procedure I have stored the arrays in a table of records like this:
type t_emp_type is record (employee_id number, department_id number);
type t_emp_tbl_type is table of t_emp_type index by binary_integer;
Where all elements in employees are stored in the employee_id column and departments are stored in the department_id column. So basically I've got a table like:
l_employee_tbl t_emp_tbl_type;
Looped through the arrays and stored the data like:
for i in 1..p_employees.count loop
l_employee_tbl(i).employee_id := p_employees(i);
l_employee_tbl(i).deparment_id := p_departments(i);
end loop;
Now I would like to compare my l_employee_tbl with a SQL table in the database. Basically I would like to join my l_employee_tbl table with a SQL table named departments on department_id, returning all department_id:s that was not found in table departments.
However, it is not possible to select from a user-defined table type. I have also tried to use the table() function and to cast l_employee_tbl, but found out it can't be done with records. And I would really like to use records or some other type where define my PL/SQL data. I know that you should not mix PL/SQL and SQL but in this case I think it is more efficient to try joining these "tables". Does anyone have a solution for this or advice to try something else out? It would be most appreciated.

Basically I would like to join my l_employee_tbl table with a SQL table named departments on department_id, returning all department_id:s that was not found in table departments. Of course, not possible as the SQL engine does not support PL/SQL user defined types. PL/SQL however support user defined SQL types. Which makes SQL defined types a lot more flexible.
However, it is not possible to select from a user-defined table type. I have also tried to use the table() function and to cast l_employee_tbl, but found out it can't be done with records. Never mind SQL and PL/SQL - as a generic programming data structure principle. How do you expect being able to cast an associative array (name-value pairs) to a standard array? The two data structures are very different. So I'm puzzled in how you expect to move a non-scalar name-value pair data structure into a non-scalar value only data structure?
And I would really like to use records or some other type where define my PL/SQL data. Why exactly? If the Java or PL/SQL data structure is populated using SQL data and database data, and wanting to use that data structure in SQL, what is the point? Why pull SQL data into a client data structure at all then - surely it is far more performant and scalable to rather keep that data in the database, and do the joins/selects/filters/etc using SQL?
There is also the issue of scalability of local data structures in PL/SQL. The PL/SQL engine runs inside an Oracle server process, consuming private process memory on the server. The bigger the data structures used in PL/SQL, the more server memory needs to be allocated to that server process. This does not scale. Especially not if 10 or more such server processes are running the same PL/SQL code and each server needs to grab large chunks of server memory.
If the data from Java comes from another source (e.g. keyboard, etc), and you need a means of storing this data server-side for use by PL/SQL and SQL. There are 2 basic choices. PL/SQL arrays for smallish amounts of data - and basing these arrays preferable on SQL data types allowing the array to be used by both SQL and PL/SQL engines. If the amount of data is not smallish, then it should be stored in the SQL engine (database) as that is designed for that exact purpose. And if the data is transient, then a GTT (global temp table) structure can be used (and indexed for optimal access).

Updating tables from Java Stored Procedures

"Oracle8i Tips & Techniques" says that Java Stored Procedures "should not modify any database tables" when called from Data Manipulation Language (DML) SQL (e.g. selects).
I have a need to do this.
Does any one know if I can call my Java from a PL/SQL stored procedure which is called from the DML SQL (e.g. via a function). That is to say java called from PL/SQL called from DML-SQL, or is this just hopeful thinking.
Any other Ideas?
Thanks in advance

Uh, not JNI but JNDI you asked. And use of JNI should be generally discouraged unless there is absolutely no other way (like co-located CORBA code for decoupling+speed). Can you direct me to a HOW-TO Oracle DB JVM configuration page? I want to know how to configure the internal DB JVM in a hurry.
Thank you,

Jimmy - You might want to buy the Following book from Oreilley Press Oracle Built in Pacakages it's very very good and came in handy when I has to write dynamic SQL (DBMS_SQL package).
You might want to try www.bookpool.com which has technical books cheaper than amazon.
