Based on the performance considerations, the SPs are more versatile and allow a broader range of inquiries and actions than the views.

Fetching a lot of data takes a lot of time. There's no cure for that, other than fetching less.
Here's some idea's you can try if you need more speed;
- verify and update the indexes (what fields are you using in your search?)
- look into (horizontal) paritioning
- select fewer columns (are you really using them all?)
- execute the optimize table[^]-command to compact the table (if deleted a lot recently)

I've never worked in C++ nor Java, but the Oracle-database speaks SQL.

What are you trying to achieve (on a higher level)? Create some kind of synchronization?

Can you post the complete message?
This would only work if the table you're inserting to has columns to match the query's result.

I have solved it ! It was a missmatch in the first select ok how do i store the query so i can call it in a store_procedure
|
|
|
|

Doesn't Oracle have a "create procedure" or something similar?

We won't actually do the writing for you but will help when you have a problem (not the entire process). Try breaking it down into smaller bits.
Write a query that compares the 2 tables and identifies the records that need to be updated.
Test it
Now change the query to do the actual update.
Create a stored procedure using the update query.
Look into database job scheduling to call the stored procedure you have created (I know SQL Server but not Oracle).
If this is beyond you then you need to get some education in working with a database, specifically Oracle which is not a trivial exercise.

Sorry my knowledge of Oracle and DB2 is very limited, I'm not going to be able to help with the details on those platforms. Oracle has a dedicated support forum, Ask Ted I think, you should get more relevant support there!

Hi everyone,
I have a table with the name is: Detail, that includes 'DateOfBirth' column (datetime type). For example: 1986-06-16 00:00:00.000
Now I want to create a store procedure to swap "day" value and "month" value for date values that have "day" and "month" value smaller 13, such as :
Origin value: 1984-05-10 (10th May)
Expected value: 1984-10-05 (5th Oct)
Do you know how can do that ?
Thanks and regards,
Tai

This is not tested and it is not the only way to do this:
UPDATE MYTABLE
SET DOB = CAST(CAST(YEAR(DOB) AS VARCHAR(4)) +
CAST(DAY(DOB) AS VARCHAR(2)) +
CAST(MONTH(DOB)AS VARCHAR(2)) AS DATETIME) +
CAST(DOB AS TIME)
|
|
|
|
|
Thank you.
I got an error when trying your code:
"Type TIME is not a defined system type"
I am using Microsoft SQL Server
|
|
|
|
|
I use TIME with SQL2008. You can use the CONVERT command to give you the time portion of the DATETIME column as a VARCHAR. (Look at 108)
