Insert performance inside a stored procedure

Hi,
I have an insert statement that inserts approx 400,000 records. The insert executes in 7 seconds if I run it from my SQL command. But when the same insert is executed as part of stored procedure, it takes ~30 mins. This is not the case with all large inserts. The behavior is sporadic - it happens with different insert statement at different times.
Please advise how I can tune this.
Thanks,
Phani

Hello,
Post your procedure code here along with insert statement.

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.

Using ALTER SESSION inside a stored procedure.... not a good idea?

Hi,
I have two stored procedures, both of which are used to query a database to find a particular book, based on ISBN. One sproc searches our main product catalogue and the other searches our suppliers feed catalogues. The stored procedures are called from a C# application via a search tool and the user is able to search on either our catalogue or our suppliers. The appropriate procedure is called based on the users choices.
However, the following behaviour is observed
I search for an ISBN (is a varchar2 field, as isbn's may contain an X if the checksum digit equates to 10) on a feed, so uses the FEED SPROC. The book is found and returned to the app in about 0.5 seconds. I can repeat this as often as i like on different books etc. always works fine.
I then do the same search but against our own catalogue, so uses our CATALOGUE SPROC. Again the book is found quickly, and the search can be repeated with the same results.
If i then go back and run our FEED SPROC then the search time increases to about 3 minutes !
Both the feed and our catalogue is in the same database, although different schema's the connections will be pooled through our app server.
I can repliacte this every single time. I think i have narrowed doen the cause of this behaviour to a few lines of code in our CATALOGUE SPROC:
-- store values
select value into v_vch_NLS_COMP from nls_session_parameters nsp where nsp.parameter = 'NLS_COMP';
select value into v_vch_NLS_SORT from nls_session_parameters nsp where nsp.parameter = 'NLS_SORT';
-- Ensure case insensitivity throughout
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_COMP = LINGUISTIC';
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_SORT = BINARY_CI';
do other stuff
-- restore session variables
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_COMP = ' || v_vch_NLS_COMP;
EXECUTE IMMEDIATE 'ALTER SESSION SET NLS_SORT = ' || v_vch_NLS_SORT;
If i remove this code then all is well, so i am assuming that using ALTER SESSION inside a stored procedure is the cause of the problem as it would be changing the execution plan of the FEEDS SPROC in some manner? Any ideas? I know i can just rewrite the sproc to avoid using this coding, but wanted to understand if i am doing something wrong by using ALTER SESSION in this manner?
Any pointers would be appreciated.

Hello (and welcome),
It may be a case of having to create a linguistic index to facilitate the queries once you set these session level parameters, i.e..,
CREATE INDEX idx_01 ON tab ((NLSSORT(col1, 'NLS_SORT=BINARY_CI'))It would appear that the setting of those parameters is invalidating index searching on the current indexes.

Calling Stored procedure inside an Stored procedure

Hi,

Kindly provide me the example...
rgds.

having a pocedure called PRCD1,
Create or Replace Procedure PRCD2 IS
egin
PRCD1;
END;
cheers !!!It will for surely err out. You cannot use "EXECUTE" inside a stored procedure.
Here's how you do it:
SQL> create or replace procedure p1 is
2 begin
3    dbms_output.put_line('I am P1');
4 end;
5 /
Procedure created.
SQL> create or replace procedure p2 is

4    p1;
5 end;
6 /
Procedure created.
SQL> set serveroutput on
SQL> exec p2
I am P2

SQL Server Free Text Search with multiple search words inside a stored procedure

I am trying to do a free text search. basically the search string is being sent to a stored procedure where it executes the free text search and returns the result.
If I search for red
flag, I want to return the results that matches both red and flag text.
Below is the query I use to return the results.
select * from customer where FREETEXT (*, '"RED" and "flag"')
This doesn't give me the desired result. Instead this one give the desired result.
select * from customer where FREETEXT (*, 'RED') AND FREETEXT (, 'FLAG')
My problem is since it's inside a stored procedure, I will not be able to create the second query where clause. I thought both query should return the same result. Am I doing something wrong here?

I am moving it to Search.

On SQL 2005, you will have to do it manually.
On SQL 2008 or later, you could have used sys.sql_expression_dependencies.

How 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

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

Extract data in to excel inside a stored procedure

Hi,
Is there a way to extract data from a table in to excel inside a stored procedure and not using SSIS?
Thanks,
Preetha

Here's a similar, simpler, sample.
Sub TestMacro()
' Create a connection object.
Dim cnPubs As ADODB.Connection
Set cnPubs = New ADODB.Connection
' Provide the connection string.
Dim strConn As String
'Use the SQL Server OLE DB Provider.
strConn = "PROVIDER=SQLOLEDB;"
'Connect to the Pubs database on the local server.
strConn = strConn & "DATA SOURCE=(local);INITIAL CATALOG=NORTHWIND.MDF;"
'Use an integrated login.
strConn = strConn & " INTEGRATED SECURITY=sspi;"
'Now open the connection.
cnPubs.Open strConn
' Create a recordset object.
Dim rsPubs As ADODB.Recordset
Set rsPubs = New ADODB.Recordset
With rsPubs
' Assign the Connection object.
.ActiveConnection = cnPubs
' Extract the required records.
.Open "SELECT * FROM Categories"
' Copy the records into cell A1 on Sheet1.
Sheet1.Range("A1").CopyFromRecordset rsPubs
' Tidy up
.Close
End With
cnPubs.Close
Set rsPubs = Nothing
Set cnPubs = Nothing
End Sub
Finally, this answers you exact question.
Option Explicit
Sub Working2()
'USE [Northwind]
'GO
'DECLARE @return_value int
'EXEC @return_value = [dbo].[TestNewProc]
' @ShipCountry = NULL
'SELECT 'Return Value' = @return_value

strConn = strConn & "Integrated Security=SSPI;"
con.Open strConn
'Put a country name in Cell E1
Set rst = con.Execute("Exec dbo.TestNewProc '" & ActiveSheet.Range("E1").Text & "'")
'The total count of records is returned to Cell A5
ActiveSheet.Range("A5").CopyFromRecordset rst
rst.Close
con.Close
End Sub
Sub Working()
'USE [Northwind]
'GO
'DECLARE @return_value int

SSRS dataset throws error when another stored procedure is called inside dataset stored procedure

Hello;
I am using Report Build 3.0, I have a simple report which gets data using dataset which is created from a Stored Procedure. I have another stored procedure which updates the data in the table which is used for the report. I want to get the live data on report everytime
the report is run so that I call that stored procedure (sp_updatedata) inside my report dataset stored procedure and here where my report fails as it throws error while creating dataset.
Here is sample:
sp_updatedata (this only returns "Command(s) completed successfully"
Create Proce sp_getReportData
As
Begin
Exec sp_updatedata -- I call it to update the data before it displays on the report
Select * from customers
End
If I remove this line it works.
Exec sp_updatedata -- I call it to update the data before it displays on the report
Thanks
Essa Mughal

Hi MESSA,
According to your description, you create a dataset based on a stored procedure. In this procedure, it calls another procedure. Now it throws error when creating dataset. Right?
In Reporting Services, when creating dataset, all the query or stored procedure will be executed in SSMS. So if the procedure can be executed in SSMS, it supposed to be working in SSRS. However, it has a limitation in SSRS. In a dataset, it can only return
one result set.
In this scenario, I don't think it's the issue of calling other procedure inside of procedure. Because we tested in our local environment, it works fine. I guess the sp_updatedata returns a result set, and the "select * from customers" returns
another result set. This might be the reason cause the error.
Reference:
Query Design Tools in Report Designer SQL Server Data Tools (SSRS)

If you still have any question, please post the error message and the store procedure (sp_updatedata).

What suggestions do you have to prevent a duplicate Logins.Login? None of the inserts for all three tables should occur if a login already exists in the Logins table. There should be a message to indicate which Login failed. I haven't yet decided if I want
all of the logins in the text file to fail if there is a duplicate, or just the one with the duplicate. I'm open to suggestions on that. So far, the duplicates only occur when someone forgets to update the tabbed delimited file and accidently runs the procedure
on an old one. I'm sure I can come up with an if statement that will accomplish this. I could maybe use WHERE EXISTS or WHERE NOT EXISTS. But I know I can get a good solution here.
I'm also aware that duplicates could be prevented in the table design. Again, I didn't design it.
I have a tab delimited file created but don't see a way to attach it.
Thanks for any help.

Thanks to all three that replied. I meant to mark the question as answered sooner. I've tried all the suggestions on a test system. All will work with maybe some slight variations. Below was my temporary quick fix. I'm working on switching to a permanent
solution based on the replies.

Use database inside a stored procedure

Hi guys, a stupid question: I'm working with several database and sometimes I'm afraid to run an alter or a create something in the wrong database, bear in mind that several database have the same tables. Sometime happens to run a query oin the db A
instead in the db B. So, the question: If I create a procedure like this,
create procedure creatingPillar as
use USA
begin
IF EXISTS (SELECT * FROM sys.objects WHERE object_id =
OBJECT_ID(N'pillarretail') AND type in (N'U'))
DROP TABLE PillarRetail
create table PillarRetail (anid int , ancore varchar(20), period dec(18,6), settlem datetime2,
settlementper int, asf dec(18,6),astlf dec (18,6), tot dec (18,6) )
insert into PillarRetail select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot from createsemipillar2011
insert into PillarRetail select select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot createsemipillar
end
but I'm wondering if is useless to put the use USA in the stored procedure by the moment that I'm creating the procedure in USA. I mean, having the SP in the USA db even if I run the procedure from another db it should run in USA. Just a stupid question
I know but I got this doubt...
Thanks

You may try as below:
create proc as below: (This will create the proc in USA database.
use USA
Go
create procedure dbo.creatingPillar as
begin
IF EXISTS (SELECT * FROM sys.objects WHERE object_id =
OBJECT_ID(N'pillarretail') AND type in (N'U'))
DROP TABLE PillarRetail
create table PillarRetail (anid int , ancore varchar(20), period dec(18,6), settlem datetime2,
settlementper int, asf dec(18,6),astlf dec (18,6), tot dec (18,6) )
insert into PillarRetail select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot from createsemipillar2011
insert into PillarRetail select select anid, ancore, Period, settlem, settlementper,
asf, astlf, tot createsemipillar
end
Then you can call as below:
Exec USA.dbo.creatingPillar

How to simulate a dml error in order to test try-catch code block inside a stored procedure

Hi,
What would be the easiest way to simulate a dml error in order to test a try catch block.
I would like to do it with a simple command from outside the stored procedure if possible.
I tried dropping the table that was updated but it hangs
Thanks,
Dani

Dropping the table that is the target of the procedure will give you an unpleasant surprise: the CATCH block will not fire. To wit, errors like missing tables can only be caught in outer scopes, but not in the procedure where the error occurs.
But you would add a fake constraint to a table which causes the update to fail. You need to do this in advance, not while running the procedure.

Using VIEW inside a stored procedure

Hi,
So I have a View designed in one file that validates someone who is authorized.
Then I have a stored procedure to display authorized stationeries created before a given date. Its takes a parameter @CreatedOn.
How can I use VIEW in my stored procedure so I can display all the authorized which are set 1 before a given date?
My VIEW:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized
FROM dbo.Stationeries
WHERE Authorized = 1
And my stored procedure:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)ASBEGINSELECTFROMENDGO
Thanks!

Try something like below, You need to replace CreatedDate column with appropriate date column in your table.
1. Alter the view to get the required date:
ALTER VIEW vw_AuthorizedStationeries AS
SELECT Authorized, CreatedDate
FROM dbo.Stationeries
WHERE Authorized = 1
2. Alter SP:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM vw_AuthorizedStationeries
WHERE CreatedDate <= @CreatedOn
END
GO
OR
You can pull required information directly from your table:
CREATE PROCEDURE usp_stationeries (@CreatedOn datetime)
AS
BEGIN
SELECT Authorized
FROM dbo.Stationeries
WHERE CreatedDate <= @CreatedOn and Authorized = 1
END
GO

Best approach for performing DMLs using stored procedures

Hi,
I have a really general question and would like to hear your say about this.
I want my application to manipulate or read data using stored procedures (or packages in that manner) and not directly using queries against the DB.
Let's say I have a table with many columns:
create table test (pkid number(10),col1 varchar2(30), col2 number(10), col3 date,...);For such a DML procedure, is it best to do something like
procedure do_update(i_pkid IN number,i_col1 IN varchar2, i_col2 IN number, i_col3 IN date,...) as
begin
   update test
   set col1=i_col1,
        col2=i_col2,
        col3=i_col3...
   where pkid=i_pkid;
   commit;
end;Or do a selective update, meaning update only a certain column every time, given only 1 column actually changes? (and how to do that - separate procedures for each column? [columns can be nulls])
Also, is it better to work with test.col1%type instead of specifying the data type in the procedure?
And one last question - If I have a table with 100 columns and I don't want to create a procedure with 100 parameters - the best approach would be to use a record?
I just need to be set on the way I start implementing things in order to do it well from the start.
Many thanks.

One last clarification (although it may be more related to c/c++ developers - maybe one of you will know):
We are working with C++ and VB against a SQLServer and my part is to translate all the existing procedures to Oracle in order to migrate the application to work with Oracle DB.
The existing procedures use an IN parameter for each column in the table and I would really like to use rowtype like you mentioned.
Since I'm not a c/c++/vb developer - is there an easy way of working with such types, or even User-Defined Types, from c/c++/vb (as in passing a rowtype record from c++ to a SP ?)
I'm not looking for the actual way - just want to know how hard it would be and how much code needs to be changed in order to be able to convince the developers that this is the RIGHT way to work.
PS. none of our developers have experience with ORACLE so they wouldn't know the answer...Not actually an Oracle server-side (SQL language or PL/SQL language) question - but a client one. And it has been a long time since I wrote a fat client using C/C++ or Delphi.
The OCI (<i>Oracle Call Interface</i>) supports advance (user defined) SQL data types. Has since Oracle 8i. So in that respect, yes the client can support custom SQL data types.
How well it does depends entirely on that client language's features wrt OCI integration. For example, Delphi 4 was release around Oracle 8i and supported custom SQL types. I would expect that most languages today (like Java and C#) will provide support for it.
As for usiong +%ROWTYPE+ - this is a PL/SQL clause as far as I know. Unsure whether it is supported by the OCI. What could support it is a pre-compiler like Pro*C. These enable you to mix pseudo SQL source code with client language source code. The pre-compilation step then replaces the pseudo SQL code with native client language calls to the OCI. The code is then compiled by that client language's compiler. Pre-compilers can pull all kinds of interesting "tricks" with their pseudo SQL code support.
The best would be to consult the applicable client language's manuals that describe the interface it supports (via OCI) to Oracle.
