Hi,
I have to migrate the oracle SQL statement to MSSQL. I want to know how to write a sql which can retrieve:
1. the user table name
2. the user table column name in the user table
3. the type of the user table column
I have already done a Oracle compliant sql :
------------------------------------------------------------
select table_name, column_name,
decode(data_type, 'VARCHAR2', 'java.lang.String',
'VARCHAR', 'java.lang.String',
'CHAR', 'java.lang.String',
'DATE', 'java.sql.Timestamp',
'NUMBER', DECODE(nvl(data_scale,0), 0, 'java.lang.Long', 'java.lang.Double'),
'LONG RAW', 'java.lang.Byte', 'BLOB', 'java.lang.Byte','java.lang.Object')
from user_tab_columns
------------------------------------------------------------
Can anyone tell me how to change it to MSSQL sql which retrieve the same value as the above sql.
Thanks.
hello, I built my application using SQLClient classes and MSSQL database i have another version of the database with Oracle, is changing to OracleClient classes the only change i have to do in order to run the program and the connection string? Thanks
i have a doubt here that would like to have some advice from u all. Can i get data from Oracle 10g database if i have an application running on MS SQL ? If can, would it be cumbersome afterall? Please advice.
hi all ms sql specialists.....i am a newbie on ms sql buti am used to oracle and toad ...and now a question (i guess this was asked xxx times befor but icouldn't find the answer easilly) :is there something powerfull like toad on oracle for mssql server? (notenterprise manager)
Hi all, Well, I have created an applicatin in asp.net and it connect to MSSQL database, and it work fine.
There is another application which was developed in Oracle and the database is oracle 8i.
Well, wat i want is whenever a form is submitted from the asp.net application, the data is inserted in the MSSQL server database and the Oracle8i database also.
Im working on a project to convert a C program from OCI(oracle) to ODBC(MsSQL).
One of the select statements uses oracle julian time:
"Select TO_NUMBER(TO_CHAR(TO_DATE('0101'||:styear,'mmddyyyy'),'J')) STYEAR from dual"
Its not a problem converting the statement, except msSQL uses 10/01/1900 as its origin for the julain calendar, where Oracle uses somewhere around 5000BC. my questions is, because this program is made to use oracle julian and need to keep it that way, how i can make the SQL conversion using oracles origin date?
Hi,I am using MSSQL 2k, and I have a linked server set up to an Oracle RDBversion 7. It goes thru an OLE DB provider for ODBC drivers on a systemDSN, which is using an Oracle RDB ODBC driver version 3.0.2.The problem occurs when I send a query that returns zero rows - queryanalyzer just does not complete nor return. This problem is not seenwhen there are rows being returned.I ran a trace and this is the error message I get-:Non-interface error: OLE DB provider MSDASQL returned an incorrectvalue for DBPROP_CONCATNULLBEHAVIOR which should be eitherDBPROPVAL_CB_NULL or DBPROPVAL_CB_NON_NULLAnybody who experienced this before has a solution?Thanks,Lawrence
I am currently migrating my database from oracle to MSSQL. My problem is that i have encountered the UTL_FILE function in Oracle and i am not finding its equivalent for MSSQL.
Can anyone help me with this plz? Is there any other way of reading and writting OS files in MSSQL?
I created a link from Oracle to SQL server. There is a trigger with insert statment in Oracle side. I got error message as follow when trigger is invoked:
SQL> insert into test1 values ('zerbra','brazi'); insert into test1 values ('zerbra','brazi') * ERROR at line 1: ORA-02047: cannot join the distributed transaction in progress ORA-06512: at "GGWEB.TRIGGER2", line 4 ORA-04088: error during execution of trigger 'GGWEB.TRIGGER2'
my simple trigger is as follows: create or replace TRIGGER TESTRI AFTER INSERT ON TEST1 FOR EACH ROW BEGIN insert into test1@sqlserver (city,state) values ('what','nine');

Hi,I'm doing an Orcle to SQL port.Simply all I want to do is run a script / DTS package that reads Oraclesequences value and writes the current value of it in to a MSSQL table - ofSequenceName, ValueCan this be done ? If so how ? (Please provide example)Steve
I lost few days to solve a problem regarding the connection to an Oracle database server (10) with goal to execute a distributed transaction.
The environment was:
Windows Server 2003 Standard MSSQL Server 2000 Standard Oracle 10g Production Edition
The connection was quite easy to make with the Microsoft driver, but the error was: Server: Msg 7391, Level 16, State 1, Line 3 The operation could not be performed because the OLE DB provider 'MSDAORA' was unable to begin a distributed transaction. OLE DB error trace [OLE/DB Provider 'MSDAORA' ITransactionJoin::JoinTransaction returned 0x8004d01b].
I tried to use the oracle odbc driver, but all kinds of errors were raised, regarding the TNS name and stuff like this. The real cause was that when you create the linked server you must to check the €œAllow inbound process€? in the provider options.
The Oracle ODBC driver allow distributed transactions.
Hello all, I will try to supply all of the information available to me to help generate some answers to the question I have. I am doing some benchmark testing of an application of how it deals with various database queries, for example oracle 10g, DB2 and MSSQL 2005. I have a very simple database called "student" that has various tables, with various columns, all as mentioned very simplistic. Each table has a few hundred rows of data, the most being one table with 2000 rows. The same database (structure and dataset), is replicated across all 3 DB's. In order to do the testing, I have been recording the same queries (select * from table_a, select * from table_b etc etc) for each database at an interface which monitors traffic between the client and db server, the problem starts here; The size of the tcpdumps are vastly greater for MSSQL vs oracle or db2. Some examples:
100 query or transaction dump: mssql=3.7mb oracl10g=133kb
50,000 query or transaction dump: mssql=1.8gb oracl10g=0.6gb db2=0.6gb
as mentioned each database's tables and data are identical to my knowledge and all queries are the same. The bloated dumps are making mssql performance numbers look bad.
So my question is: What could be the reason for MSSQLs client/server queries to contain so much information, has anyone else come across this? Is there any setting or something I could try to minimize it?
How many result-rows does mssql return should be used asynchronous method to use mssql cursor, can get the best performance in any time in any result offset?
i want to make the cursor fast in any time whatever how many results returned
i was planning to create a database migration tool .. its a certain database of a DMS (document management system) to another DMS (two different DMS)... from DMS using msde 2000 server .. and tranfer to a DMS using a postgre sql or mssql .. depends ..
they have different table structures and names . . :D
i was thing of what language shall i use.. or what language is the best to work on this kind of project :)

I am a bit new to the MSSQL server. In our application, we use so many SQL queries. To imporve the performance, we used the Database enigine Tuning tool to create the indexes. The older version of the application supports MSSQL 2000 also. To re-create these new indexes, I have an issue in running these "CREATE INDEX" commands as the statements generated for index creation are done in MSSQL 2005. The statements include "INCLUDES" keyword which is supported in MSSQL 2005 but not in MSSQL 2000.
Ex:-
CREATE INDEX IND_001_PPM_PA ON PPM_PROCESS_ACTIVITY
I am currently work on mssql 6.5. On my workstation, I have mssql 6.5 cient software.
However, I would like to install mssql 7.0 server on my nt workstation and work with it to become familiar with 7.0. Can I install mssql 7.0 server on my nt workstation? Can mssql 6.5 client coexist with mssql 7.0 on the same machine if they are in different directories?
Ben writes "I have a sql script that doesn't function very well when it's executed on a SQL 2000 server.

I need to be converted to a script that can be executed on both MSSQL 2000 and MSSQL 2005.
I was wondering if somebody there could help me with this problem?!
I've been tasked to move our production databases on MSSQL 2000 to 2005. I've supported MSSQL since version 6.5 and performed migrations to successor versions.
Current Environment is MSSQL 2000 32-bit with current Service Packs.
I've performed mock migrations on Test servers upgrading all Production instances simultaneously from MSSQL 2000 to 2005 32-bit. The Test environment is identical to Production minus server name, IP etc. Also I have a separate server with MSSQL 2005 installed where I use the DETACH / ATTACH and BACKUP / RESTORE method for migration / acceptance testing. There are approximately 30 databases totaling 70 GB. This has gone as expected and fairly successful. Vendors have been coordinated with to update code and staff for acceptance testing.
I'd prefer going directly to MSSQL 2005 64-bit instead if possible due to memory benefits etc. This is where I'd like some feedback prior to borrowing a 64-bit server for testing.
Upgrade options:
1. Is it better to migrate from MSSQL 2000 32-bit to 2005 64-bit via: a. DETACH / ATTACH b. BACKUP / RESTORE c. Is one method more advantageous relating to the end result? 2. Regarding XP clients, have issues been experienced with the default SQL Server driver or is an alternate recommended for XP clients to connect to a MSSQL 64-bit server databases? 3. If you have performed this migration and have relevant experience please pass them along.
I have an issue using parameterised reports connecting to Oracle using "ODBC" and "Microsoft OLE DB Provider for Oracle" using parameteried reports. The following error is generated "ORA-01008 not all variables bound (Microsoft OLE DB Provider for Oracle)" and a similiar one for ODBC. It works fine for simple reports. Do these 2 drivers have issues passing parameters for a remote Oracle query? Thanks.
Exception from HRESULT: 0xC0204018 (Microsoft.SqlServer.DTSPipelineWrap)
------------------------------ BUTTONS:
OK ------------------------------ For most of my queries to Oracle I can cast the columns to get rid of the error (CAST x AS DECIMAL(10) etc), but this does not work for:
1) Union
I have a select like "SELECT NVL(myColumn, 0) .... FROM myTable UNION SELECT 0 AS myColumn, .... FROM DUAL"
Even if I cast the columns in both selects (SELECT CAST(NVL(myColumn, 0) AS DECIMAL(10, 0) .... UNION SELECT CAST(0 AS DECIMAL(10, 0)) AS myColumn, .... FROM DUAL) I still get the error above.
2) SQL command from variable
The select basically looks like this:
"SELECT Column1, Column2, ... FROM myTable WHERE Updated BETWEEN User::LastLoad AND User::CurrentLoad"
Again, even if I cast all columns (like in the union), I still get the same error.
we recently got a scenario that we need to get the data from oracle tables which is installed on third party servers. we have sqlserver installed on ourservers. so they have created a DBLINK in oracle server to our sqlserver and published the DBLINK name.
what are the next steps that i need to follow on my sqlserver in order to access the oracle tables ?
On my dev server I have working ssis packages that use connections Microsoft OLEDB provider for Oracle MSDAORA.1 and Oracle provider for oledb and OracleClient data provider.
I use one or the other according to my needs.
In anticipation and to prepare for the build of a new production server, I have build a test server from scratch and deployed to it the entire dev.
Almost everything works except Microsoft OLEDB provider for Oracle.
ssis packages on the test machine will return an error
Error at Pull Calendar from One [OLE DB Source [1]]: The AcquireConnection method call to the connection manager "one.oledb" failed with error code 0xC0202009.
Error at Pull Calendar from One [DTS.Pipeline]: component "OLE DB Source" (1) failed validation and returned error code 0xC020801C.
[Connection manager "one.oledb"]: An OLE DB error has occurred. Error code: 0x80004005.
An OLE DB record is available. Source: "Microsoft OLE DB Provider for Oracle" Hresult: 0x80004005 Description: "Oracle error occurred, but error message could not be retrieved from Oracle.".
I have used the same installers for OS, SQL and Oracle SQL*Net on both dev and test machines. The install and then the restore/deployment on Test went fine.
Does anyone could point me to the right direction to solve this issue?
I am trying to make an oracle publiching from sql server 2005 enterprise final release, i installed the oracle client 10.2 (10g) on the same server where sql server already installed, i made different connection to oracle database instance and it was ok.

I've been searching for a solution for this for a week-ish, so I thought I would post my quesiton directly. Here is my scenario..
Source: MS SQL Server
Destination: Oracle 10g
The destination table has a partition set on a column called "DATE_HIGH". How do I populate this date high column in my package? Currently I just have a source object, and a destination object, but I'm unclear how to populate this field in the destination. I've read one blog that states "use OLE DB Command" - but that isn't enough information for me to implement - Can someone be more specific in these steps? Here is an example of what my newb-ness needs to understand
OLE DB Source (Select * from Table) ---> OLE DB Command (What query goes here?) --> OLE DB Destination.
Second part of my question: There is a second column called "ROW_NUM" and there is an Oracle Sequence provided to me... What objects do I need (Source, Destination, OLE DB Command etc...) and how do I call this sequence to populate on the fly as I'm loading data from my source?
If these are simple questions - my appologies, I am new to the product.
I have designed a DTS package which will migrate a view from Sqlserver 2000 to Oracle.My package is using Microsoft OLEDB provider for Oracle driver for connecting to oracle.Im able to execute this package on the my system ie on the system where sqlclient is installed(Oracle client is also installed on my machine) .But when im doing it on the server im not able to do it.The Connection to Oracle Fails. I wanted to know in order to connect to Oracle from the server,is it necessary that Oracle has to be installed on the server?.If yes, is it enough if i install oracle client on the server or Oracle Server version has to be installed on Server.
