Global Temp Table or PL/SQL Table

I am trying to determine if this can be done only using PL/SQL table. If not, will the usage of the global temp table affects the performance.
Here is the situation,
I have a data block that is based on a stored procedure. This stored procedure will return table of records from different database tables with join conditions. Some of the fields within the table of records will not have data returned from database tables. They will be the fields displayed on the form and the data will be entered by user.
For example:
Records will look like:
Id          (will be populated by procedure)
Hist_avg     (will be populated by procedure)
My_avg     (will be used as field on the form so that user can enter their own avg)
Cheked     (will be populated by procedure)
My questions are:
1.     Is this doable in form using a data block based on PL/SQL table?
2.     Will users be able to manipulate (update) the data that based on the PL/SQL table in the memory as they wish and invoke the procedure to update the underlying table when clicking on a button (Update Avg)?
3.     What is the advantage of using PL/SQL table and global temp table from database and form point of views?
Any info is appreciated.

Transfer data from SAP TABLES to a SQL table

Hi,
I need to transfer data from SAP tables to a SQL table. Please suggest the best way as well as the steps please.

Hi
Step 1: Create an entry for the External database in DBCON table using Trxn: DBCA.
Field Name Description Value (For: E.g.:)
CON_NAME Logical name
for database con RAJ
DBMS Database system MSS
USER_NAME Database user <username>
PASSWORD Password for setting up
the connection
to the database <pwd>/<pwd>
CON_ENV Database-specific MSSQL_SERVER=depotserver MSSQL_DBNAME=HOF_INDORE
DB_RECO Availability type for an open database connect
Then, you can define internal table and code the following way:
DATA: BEGIN OF wa,
c_locid(3),
c_locname(50),
c_locstate(5),
END OF wa.
EXEC SQL.
CONNECT TO 'RAJ' AS 'V'
ENDEXEC.
EXEC SQL.
SET CONNECTION 'V'
ENDEXEC.
< Populate SAP data into an internal table >
Loop on itab.
EXEC SQL.
< code here for populating data into MS-SQL Server table>
ENDEXEC.
Endloop.

Diference b/w normal tables and pl/sql tables

what is the diference b/w normal tables and pl/sql tables.
already we have tables then what is the purpose of pl/sql tables.
what are the advantages of pl/sql tables compare nor mal tables.

user10447332 wrote:

They are memory structures that store data and go away when your program stops running - essentially arrays or "tables" in other programming languages. "normal" ("heap") tables are stored on disk and are persistant - they store data permanently.
already we have tables then what is the purpose of pl/sql tables.Collections are used to store data temporarily in memory, when it will be accessed shortly or repeatedly for fast access. This works best with smaller data sets because if you store too much data in a collection you can run out of memory to use
what are the advantages of pl/sql tables compare nor mal tables.Collections give you faster access to data you need to read more than once during the same application. They work well for fast lookups and for smaller data sets can improve program performance slightly with the use of the bulk collect and forall PL/SQL operators under the right conditions.

How to add hash table values to SQL Table using Powershell

Hi,
I have sharepoint list with four(column1, column2, column3,column4)columns.I am reading the list column values and adding to hashtable. Now I want to add values from hastable to SQL table with four(column1, column2, colum3,column4)columns using powershell.
I have written the following script for single column but I would like to know how to add values for multiple columns.
if(($key -eq "Column1") )
$SqlQuery = "INSERT INTO [TableName] ([Column1]) VALUES ('" + $HashTable.Item($key) +"')"
#Set new object to connect to sql database
$connection = new-object system.data.sqlclient.sqlconnection
$Connection.ConnectionString ="server=SQLServerName;database=SQLDBName;Integrated Security = True;"
$connection #List connection information
$connection.open() #Open Connection

Hi AOk2013,
Not knowledgable on PowercShell, based on my understanding on HashTable in Java, Some modification you can make in your code to achieve your requirement.
If the Keys in HashTable are "Column1","Column2","Column3","Column4", you can reference below.
if(($key -eq "Column1") ) #what is the purposed of this if ?
#$SqlQuery = "INSERT INTO [TableName] ([Term]) VALUES ('" + $HashTable.Item($key) +"')"
#specify the real column names in the table
$SqlQuery = "INSERT INTO [TableName] ([ColumnA],[ColumnB],[ColumnC],[ColumnD]) VALUES ('" + $HashTable.Item("Column1") +"','"+ $HashTable.Item("Column2") +"','"+$HashTable.Item("Column3") +"','"+$HashTable.Item("Column4") +"')"
#Set new object to connect to sql database
$connection = new-object system.data.sqlclient.sqlconnection
$Connection.ConnectionString ="server=SQLServerName;database=SQLDBName;Integrated Security = True;"
$connection #List connection information
$connection.open() #Open Connection
$Cmd = New-Object System.Data.SqlClient.SqlCommand
$Cmd.CommandText = $SqlQuery
$Cmd.Connection = $connection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$DataSet = New-Object System.Data.DataSet
$SqlAdapter.Fill($DataSet)
$DataSet.Tables[0]

Importing 30 tables into one SQL Table (Help Required)

Dear Experts,
I am new in SQL server, actually i need to gather 30 different excel file in one sql server table and i have imported all excel file in different databases, all tables have 186 different columns and datatypes. I couldnt change data type while conversion.
Now all columns have different data type which are occupying extra space in my database.
Now the problem is that i need to convert all databases into one database or table. Although i have created a table but i dont have idea how to import all table into one table and defining datatype in new table while importing the old tables.
Please help me in this matter or if any body has skype or any other chatting id please do let me know so that i may explain it better.
Thanking you in advance.
Best Regards,

There are several things you can try. If you have SSIS, take a look at this.
http://www.singhvikash.in/2013/06/ssis-how-to-load-multiple-excel-files.html
https://www.simple-talk.com/sql/ssis/importing-excel-data-into-sql-server-via-ssis-questions-you-were-too-shy-to-ask/
Also, if your files have virtually the same name, like files with dates in the name, you can loop through files in your folder, and increment the loop with each run through.
DECLARE @intFlag
INT
SET @intFlag
= 1
WHILE (@intFlag
<=30)
BEGIN
PRINT @intFlag
declare @fullpath1
varchar(1000)
select @fullpath1
= '''\\path to your files\'
+ convert(varchar,
getdate()- @intFlag
, 112)
+ '_your-text-file-name.txt'''
declare @cmd1
nvarchar(1000)
select @cmd1
= 'bulk insert [dbo].[your-table-name] from '
+ @fullpath1 +
' with (FIELDTERMINATOR = ''\t'', FIRSTROW = 2, ROWTERMINATOR=''0x0a'')'
exec (@cmd1)
SET @intFlag
= @intFlag + 1
END

Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Global Temp Table vs. PL/SQL Table

Hi,
I'm trying to find out which better (efficient) to use in coding, a Global Temporary Table or PL/SQL table. The process requires evaluation to what data stored in the tbale.
Thanks in advance.

Ok, let me restate this.
not carteasian product, carteasian LIKE ... where there is a many to many join between 2 fields (a resolution table).
Anyway, on Sybase/SQL Server if you need 3 fields from a table, 3 tables away,
you are allow to do a bulk / set update
UPDATE tempTable
field1 = t3X
field2 = t3Y
field3 = t3Z
FROM tempTable, t1, t2, t3
Where (joins)
In Oracle, the only way to do this is with 3 subselects
UPDATE tempTable
field1 = ( select t3X FROM tempTable, t1, t2, t3
Where (joins) ) ,
field2 = (select t3Y FROM tempTable, t1, t2, t3
Where (joins) ),
field3 = (select t3Z FROM tempTable, t1, t2, t3
Where (joins) ),
while this works, it does not seem effcient or elegant compared to the Sybase Solution.
By the way I am dealing with a design that preceeds me and I joined the team from a DIFFERERENT TEAM with a DIFFERENT background. I am neither stupid nor a poor designer, however I am ignorant of the Oracle ways and figured this would be the best place to look for the answer. Hans seems to have the best grasp of the request, does he have a CONSTRUCTIVE comment?
Thank you in advance.

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).

Global temp table problem w/ODP?

I'm using the current version of the ODP .NET data adapter to access a global temporary table on an Oracle
9.2.0.4.0 server created with -
CREATE GLOBAL TEMPORARY TABLE euik_dex_open_tasks_temp1
(resource_id NUMBER,
task_assignment_id NUMBER,
task_id NUMBER,
incident_id NUMBER,
customer_product_id NUMBER,
inventory_item_id NUMBER,
contract_service_id NUMBER)
ON COMMIT DELETE ROWS
(See below for what is returned from the data dictionary for this table)
If I use SQLPlus to insert a row into this table, then query the table immediately, I see the inserted row.
If I use the same exact SQL through the ODP adapter, the ExecuteNonQuery statement returns the fact the 1 row was inserted. However, doing a SELECT from the table immediately after the INSERT, no rows are returned. See the .NET test ap, below.
Also, note that if I use a global temp table made with ON COMMIT PRESERVE ROWS, the ODP adapter works fine.
What am I doing wrong? Thanks in advance...

Andrew,
As David indicated if you do not wish to have "auto commit mode" you just need to use a transaction object to manually control the transaction.
I'm just nervous at the idea of ODP.NET initiating interactions I am not aware of.I think it would be more fair to say "finishing interactions" in this case rather than "initiating interactions" but you could always just run a SQL trace from the database to see exactly what is happening if you are concerned.

A better way than a global temp table to reuse a distinct select?

I get the impression from other threads that global temp tables are frowned upon so I'm wondering if there is a better way to simplify what I need to do. I have some values scattered about a table with a relatively large number of records. I need to distinct them out and delete from 21 other tables where those values also occur. The values have a really low cardinality to the number of rows. Out of 500K+ rows there might be a dozen distinct values.
I thought that rather than 21 cases of:
DELETE FROM x1..21 WHERE value IN (SELECT DISTINCT value FROM Y)
It would be better for performance to populate a global temp table with the distinct first:
INSERT INTO gtt SELECT DISTINCT value FROM Y
DELETE FROM x1..21 WHERE value IN (SELECT value FROM GTT)
People asking questions about GTT's seem to get blasted so is this another case where there's a better way to do this? Should I just have the system bite the bullet on the DISTINCT 21 times? The big table truncates and reloads and needs to do so quickly so I was hoping not to have to index it and meddle with disable/rebuild index but if that's better than a temp table, I'll have to make do.
As far as I understand WITH ... USING can't be used to delete from multiple tables or can it?

Almost, but not quite, as efficient as using a temporary table would be to use a PL/SQL collection and FORALL statements and/or referencing the collection in your subsequent statements). Something like
DECLARE
TYPE value_nt IS TABLE OF y.value%type;
l_values value_nt;
BEGIN
SELECT distinct value
    BULK COLLECT INTO l_values
    FROM y;
FORALL i IN 1 .. l_values.count
    DELETE FROM x1
     WHERE value = l_values(i);
FORALL i IN 1 .. l_values.count
    DELETE FROM x2
     WHERE value = l_values(i);
END;or
CREATE TYPE value_nt
IS TABLE OF varchar2(100); -- Guessing at the type of y.value
DECLARE
l_values value_nt;
BEGIN
SELECT distinct value
    BULK COLLECT INTO l_values
    FROM y;
DELETE FROM x1
   WHERE value = (SELECT /*+ cardinality(v 10) */ column_value from table( l_values ) v );
DELETE FROM x2
   WHERE value = (SELECT /*+ cardinality(v 10) */ column_value from table( l_values ) v );
END;Justin

Hi,
"CREATE GLOBAL TEPORARY TABLE ..." is not a PL/SQL command; it is a SQL command only.
Create the table, using that statement, before running the PL/SQL block.
You can issue SQL statements from within PL/SQL using the EXECUTE IMMEDIATE command, but this is rarely a good idea.
I assume the PL/SQL code is meant to create the table and then populate it.
You should split those into two separate pieces of code. You'll only want to create the table once, no matter how many times you use it. I assume you'll want to populate it the same way many times. Remember, the "TEMPORARY" in "GLOBAL TEMPORARY TABLE" refers to the data, not the table. When you end a transaction (or a session, depending on whther you want "ON COMMIT DELETE ROWS" or "ON COMMIT PRESERVE ROWS"), the data disappears, but the now-empty stays, ready to be populated for the next transaction (or session).

Global temporary table in PL/SQL called from APEX page

I have a global temporary table in a PL/SQL procedure that is called from an APEX page.
The global temp table is populated with data as the procedure runs and then at the end of the procedure I do a create_collection_from_query_b to populate a collection with the data from the temp table. (I do this b/c it is much faster than creating the collection and doing an add_member for each row.)
The problem is that there are no commits in my procedure but I cannot get the bulk insert to work unless I define the temp table as on commit preserve rows.
Can anyone shed any light on this issue.
Thanks,
Andrew

If the process calls the PL/SQL procedure and the temp table is in the procedure, wouldn't the commit fire after all the PL/SQL code is complete which would be after the bulk insert from the temp table to my collection?Yes, but at any point in the procedure containing code like
:APEX_ITEM := ...or
select ... into :APEX_ITEM from ...or
my_procedure(p_in => ..., p_out => :APEX_ITEM, ...);or
apex_util.set_session_state(...);then APEX will commit whilst maintaining session state.
If you don't have any of these events in the procedure, then test to see if the commit is occurring in <tt>apex_collection.create_collection_from_query_b</tt> prior to creation of the collection.

Update Global Temp Table in Oracle 11g

Hi Experts,
Scenario: I have stored procedure A which calls procedure B. Procedure B uses Global temp Tables(With On Commit Preserve Rows) to work with the data.
I am trying to update one of the GTT in Proc B but unable to do it .. via SQL or via PL/SQL Cursor/Collection. There is no syntax nor logical error and the PL/SQL proc completes execution successfully but the rows are not getting updated. My Db version is Oralce 11g 11203.
Update statement is something like this.
Update <GTT>
SET amount1 = amount1 *-1, amount2 = amount2 *-1
where field1 = <value>
and field2 in ( Select filed2 from <table1> );
Any idea why would this update not work? Has anyone faced this issue in Oracle 11g??
Appreciate your suggestions & thanks in Advance for your inputs.
Cheers,
MS

You already told us that it DOES work - no errors or exceptions.
It is trivial to determine if that update will do anything - just turn it into a SELECT and see if any rows are ntselected:
v_cnt INTEGER;
SELECT COUNT(*) INTO v_cnt FROM myGTT
WHERE field1 = <value>
AND field2 in (Select field2 from <tablee1>);
Then take a look at the 'count' that you get.

How can I get rid of Global Temp Table

Hello,
I've been writing PL/SQL stored proc for creating reports on VB.NET front end. Until now, I've been using session specific global temp table to store intermediate results and at the end I pass the result set to .NET via reference cursor. The reports are created by simply binding the ref cursor result sets to .NET grids. It's been working fine, but I am kind of bothered by the temp tables. I looked on other options, but couldn't really come up with one.
Can somebody suggest me how I can get rid of those temp tables? Thanks,

Tubby, that's exactly I was trying to do. I think that table type has to be defined in database, not within PL/SQL. How can I create that table of user defined record type? I tried that, but it doesn't allow me. I think I am missing something. For example,
create type group_t is record
(A varchar2,
B number,
C number)
now inside sp, i have something like:
type my_group is table of group_t index by binary_integer
now I have sp cursor as
cursor cur_test IS 'ABC' as A, 1 as B, 5 as C
now i do something like this. My original queries are longer and much more complicated so please don't suggest you can directly open ref cursor for this query.
FETCH cur_test BULK COLLECT INTO my_group;
Then I do all the processing, calculations, totals, sub-totals, and insert into temp table and return via ref cursor.
My problem is I can't directly fetch into the above table you mentioned. How should I go about in this situation?
Maybe I should STOP thinking about this approach and just do whatever I've been doing or solve it through pure SQL. However, there are tons of problems with pure SQL approach.
