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.

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 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

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?
Thank you for your time.

I am a complete novice so I would appreciate any help or suggestions.
I have two databases : 1 development DB, 1 production DB (both are SQL Server)
I make changes to development DB on a daily basis and I need a method to bring these changes across to production DB.
Currently I query the selected table in the development DB and write the DataSet to an XML file.
##
objDataSet.WriteXml(Server.MapPath("xDataDictionary.xml"))
##
Once I go to client site (where production DB is located) I want to generate a DataSet (which I am able to do) and compare this DataSet with the DataSet created when I read in the XML file.
##
'read in XML file
XMLDataSet.ReadXML(Server.MapPath("xDataDictionary.xml"))
##
There is a unique identifier in the table and XML file called 'FieldID'.
What I need to do is compare DataSet (from Production DB) with DataSet from XML file.
If there is a 'FieldID' in the DataSet from XML file that IS NOT in DataSet from ProductionDB I want to insert this node/row into the database.
Any suggestions?

I was wondering if anyone knows if there is any software available or
if it is easy to implement the following.
We are running a SQL Server database locally in house and also have
the exact same database running on a hosted webserver. The data
changes on both versions of the database daily and what we need to do
is figure out a simple easy / cheap way to have the two databases
synchronize with each other every evening so that the data is exactly
the same every morning.
I would appreciate any input.
thanks

Hi,
I am having this scenario; I have 2 SQL Server 2005 databases, they are basically identical in structure. The first one is used by my web application and the other is by desktop application ... I created the web db for security reasons ,.. i dont want online users to have access to the major backed (desktop db) directly so the web app is writing to the web db ... now, I want to update my major backend as transactions to the web db happen and vice versa to keep the users of both applicaions happy ... Is there a good design patterns for that? I am thinking of using db triggers for this but not sure on the implementation details ...
Your help is much appreciated

Hi,
I'm currently working on a Database Synchronization project and I wondered if anyone had any ideas other than what I've got so far. The context of this project is that we have a central server which stores data for 10 different locations in a consolidated database. Each store contains a replica of that database, but with only data relevant to their own operation.
Store owners can change data at the store level or chain owners can change data at the central level, but for either change the other level has to be notified. I currently have 2 ideas on how to do this.
Note: I am using MS SQL Server 7 for the central, but MSDE (Desktop Edition) for the store levels. So, replication from the store to the server is not available. I think I need to actually code this on my own.

Please can somebody help me with the following:
Our company has an enterprize site (a very large one). From time to time we need to make changes in it. In other words, we had to synchronize one database (local where we make all changes) and database on hosting. So, we did it manually (wrote scripts and inserted them in database on hosting). But as the databases grew it became impossible to synchronize everything manually. So we need some tool which could cope with this task. The problem is that, as I know, there are many tools which can do it, but we are tight in time and can't evaluate them all. Please share your ideas on what tool is worth evaluating?
Thanks in advance.

I am not a SQL developer by any means. I have a application to build for a Valet company that will require a laptop on site with no internet connectivity to function locally. There will be about 15 locations that all operate independently. After the day is done, the laptops will connect to the internet and upload all data to a hosted SQL server on the internet for centralized data storage and reporting. After a successful upload, the client database will be purged and start fresh the next day. Should this be doe with MYSql on the client and SQL server at the data center? I have some people recommending Progress database but it is expensive. I am out of my element when it comes to syncing db's so any advise is appreciated. Thanks-

Dear All,
I’m having three databases with same data in three different locations. Now three users adding records to the particular databases respectively. I want all the data from server A to be there at aerver B and C. all the updations at server B should be there at Server A and server C. as well as same updations at C also. It is not possible to implement replication as all the servers are at long distance. How can I update every database with the other server’s data? I’d like to update day wise. Is there any tool to generate script on that particular date period? Experts, I think you understood my scenario, please let me know the tools or list of best possibilities for me.
I’m thinking of Incremental backup. Guide me in this scenario.
Thanks in advance.
