I disagree on the "generally strongly" advice.
Manageability, consistency, security, reliability, portability are all reasons for storing binaries in the database.
Storing binaries in the database means that you have db-enforced referential integrity, one point of entry for the backup, one place to set security...

why this code returns all rows although I specified the condition? how to correct?
CREATE OR REPLACE FUNCTION fn_get_resume_details2(resume_id integer)
RETURNS SETOF record AS
$$select resume_id, resume_title, objective_title, objective_text, summary_title, summary_text from resume_details where resume_id = resume_id;
$$LANGUAGE sql;
</pre>

In your where clause, resume_id = resume_id, that is the same as saying where 1 = 1. It will be true for all rows. I'd recommend changing the name of your parameter to be different from the column name.
CREATE OR REPLACE FUNCTION fn_get_resume_details2(in_resume_id integer)
RETURNS SETOF record AS
$$select resume_id
,resume_title
,objective_title
,objective_text
,summary_title
,summary_text
from resume_details
where resume_id = in_resume_id;
$$LANGUAGE sql;

I have a clinic management software on C# WinForm and planning to have an online interface for eServices. I am planning to move from SQL Server because of the cost and the Express Edition is not enough capacity..
So for such project, if you are the decision make then which database you'll move to? PostgreSQL or MySQL? or maybe another FREE db?

I'm trying to use C# to add a column to an MS Access database, but I'm having trouble with the syntax.
My SQL string amounts to something like this:
ALTER TABLE t_customer <br />
ADD person_id integer <br />
CONSTRAINT FK_person_id <br />
FOREIGN KEY (person_id) <br />
REFERENCES t_person (person_id)
I can't find any difference to the MSDN example syntax.
Can you tell me where the error is?
Thanks!

Not without seeing your code, but I could do an educated guess. You're referring to this[^] example? The example on that page lists this code;
dbs.Execute "ALTER TABLE Orders " _
& "ADD CONSTRAINT OrdersRelationship " _
& "FOREIGN KEY (EmployeeID) " _
& "REFERENCES Employees (EmployeeID);"
Are you concatenating strings the same way? If so, check the resulting string - it may be missing the space at the end of each line; between "Orders" and "ADD", between "OrdersRelationShip" and "FOREIGN" and between ")" and "REFERENCES".

the same way i have another 11 child tables, when i want to insert data using

SELECT

WHERE
a.int_voucher_month=int_month and a.int_voucher_year=int_year and a.str_voucher_code=b.str_voucher_code;
It will Insert in Both Master as well as one child table.
IF any mistake in above code.. Please mention...

Not sure the purpose of the child tables. You also need a rule for when an update occurs on the master table since you are replicating data in two tables.
Why not only have the master table with single inserts and create views on the master table that have the hard coded date ranges built into the views?

Thank you for your quick reply Chris.
I would be having around 5 million records per month in my table. That is why I thought of partitioning the table on the basis of months to generate month-wise reports. May be I got it wrong, but my understanding was that the data would be inserted only in the child tables and not the master table.
Due to the amount of data, the query being fired takes 4-5 mins to return any results (basically it is using the WITH RECURSIVE clause). I used indexes and also tried optimizing the query but it hardly made any difference. I might have to write the query in a different manner, but the problem is still with the amount of data in the table.
Kindly suggest on how to resolve this issue.
Thank you in advance.

hello all,
is it possible to load data from csv file into an oracle table using an ODBC bulk command ? 
|
|
|
|

why don't you use Sqlldr.exe for Bulk insert

Because I am coding an application in VB6, I have only an ODBC link to the database

You can Use Sqlldr.exe in VB6..,
Why are you going to break your head again for bulk insert concept., there is already well tested component is giving by the Oralce..,
Use the Shell executions to execute the sqlldr.., No need of ODBC..,
Thanks
