How many Objects u can create in DB

Ah, good old u.. He was famous for creating objects in DB. Word is he once created 12 at a time, and up till 42 in a single day.
Too bad he passed away. Even sadder that a lot of people still haven't heard..

There are a number of ways to find the answers to your questions. For some simple things, you can create a test case and use a larger and larger number, until you get an error that tells you that you have exceeded the maximum. You can also search the online documentation. You can search on the words in your questions or you can search on more general terms like "limits". Here are a few examples of the sections of the online documentaiton that contain answers to some of your questions:

http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/limits003.htm#i288032

The answers should be depending on you hardware...you can create as many as databases and tables as long as you have the sources. Hence, answer should be == (n-1)

1) How many DB can be created in a machine

depends on the HDD space you can make many DB's no restriction.

2) How many column can be used in a Select Statement

1000

3) How many tables that can be joined in a select statement

before 8i it was only 15 but after tht. itz increased to 255 i think but not sure.

4) How many SUB QUR that can be written in a session

in a session u can create many.
i think the question sld be

" How many SUB QUR tht can be written in a SELECT statement"

if so then the above said ans for this also.

5) How many column can we hav in a Table

ORA-01792: maximum number of columns in a table or view is 1000
Cause: An attempt was made to create a table or view with more than 1000 columns, or to add more columns to a table or view which pushes it over the maximum allowable limit of 1000. Note that unused columns in the table are counted toward the 1000 column limit.
Action: If the error is a result of a CREATE command, then reduce the number of columns in the command and resubmit. If the error is a result of an ALTER TABLE command, then there are two options: 1) If the table contained unused columns, remove them by executing ALTER TABLE DROP UNUSED COLUMNS before adding new columns; 2) Reduce the number of columns in the command and resubmit.

6) What is the Maximum size of Procedure

4 GB

Better post your source at the same time as the answers, then we can estimate if they are valid ones.

@deviji:
I successfully selected 3999 columns from dual. I did it in both 9iR2 and 10gR2. My conclusion is that your answer to question 2 is wrong. I generated the select statement with this query:

SELECT *
FROM   (SELECT     /*+ALL_ROWS*/
                   ', ' || LEVEL || ' column_' || LEVEL x
        FROM       DUAL
        CONNECT BY LEVEL < 4000)

All you need to do is modify the first line of the result set and add a "from dual" and you're off. I didn't check the rest of your answers (yet) but I'd certainly double check.

Actually, there IS a restriction. Regarding the fact that object names should contain only aphanumerics along with several special characters, maximum allowed length of an object name and object name uniqueness, we might, actually, hit the number of objects limit. Not that it is probable, but possible - yes.

I somehow think you will run into some internal limit before that.. some id column or some sequence or something.

Although, of course you can have more than 1 object of the same name in different schemas. As Frank says, you would hit other limits loooooong before you broke the above mentioned limits Smile

No objections.

My intention wasn't mentioning all possible causes. I just wanted to point out that there ARE restrictions (as opposed to Deviji's "no restrictions").

Yes, and Littlefoot pointed out that there is a logical restriction. Granted that restriction is huge, but it is not true to say that there is no restriction on the number of objects that can be created

hi Maaher,
just visit this site
http://download.oracle.com/docs/cd/B28359_01/server.111/b28320/limits003.htm#i288032

it says number of columns per table is 1000. that is why i said the columns you can retrieve from a table could be 1000.
but i forgot about joins.

so can any one tell me what could be the maximum number of columns one can retrieve in a single select statement?

and Michel i think you answered '42' for number of parameters one can pass to a procedure isn't it?
see this

http://download.oracle.com/docs/cd/B10500_01/appdev.920/a96624/e_limits.htm

it says,
parameters passed to a function or procedure 64K
so.......what can we conclude from this?

regards,
viji

You'd better rethink your logic if you ever run into one of those limits.
Why are you so keen on knowing how many columns you can have in a select, or in fact the other limits?
And as for Michel's 42: google for that number if it does not ring a bell. It is about the most famous number.

I had to test it myself. It's a logical deduction you made, but apparently not correct.

I'd listen to Frank: if anyone is hitting any of these limits, the design probably needs a makeover. It sure would be a nightmare to maintain. One of the limits I have ever encountered in my professional life is the size of a VARCHAR2.
