Good Morning Sir,
I am willing to install oracle database on my computer. So I have downloaded the database from here Oracle Database Software Downloads | Oracle Technology Network | Oracle[^] I found 12c is the latest database and I have downloaded it. Mine is a Windows 10 64 bit Operating System based on x-64 processor so the database will work in my computer since Microsoft Windows x64 (64-bit) is only present.
I created the oracle account and started installing the database, there were few steps prompted to me before installing the database, I've chosen the default settings and moved on. But I got this error,
Failed to add VISWESWARAN\Visweswaran install user to %2% group
I have searched the internet for this error and referred this Configuring Users, Groups and Environments for Oracle Database[^] thread but I found nothing.
Sir, could you please help me
Thank you for your time sir.

Have a look at Oracle 12c Install on Windows
It is for Windows 7, but I guess, the installation process on Windows 10 should not differ too much.

Thank you sir for your kind reply. But I have tried that and I see the same error message 
|
|
|
|
|
Can you elaborate on this one
I created the oracle account and started installing the database, there were few steps prompted to me before installing the database, I've chosen the default settings and moved on

Sir,
I mean the initial steps for installing the database like
[radio-button] [selected] Install and configure database
[radio-button] Install database
[Back] [Next]
here Install and configure is the default selected option, all I did is clicked next. since I am a beginner in Oracle database, I've selected the default options without modifying various values.
No, sir there is no guest user account in my computer, I have only one account in my PC which is admin
Thank you sir for your time and kind help

I believe that you are installing the software as an Administrator. Right?

These are not the data you are looking for... move along.

- Could you post the exact message?
- Could you explain what and how you did?
- Was it in MS SQL Server or in some other DBMS?

We do not provide free code or projects. You should help yourself and try to find the code from here. You are most likely to get a project sample, and work for that.
Try searching, "mysql data definition sql php" on the top right corner.

Hi,
I want to avoid dynamic sql but my Table name varies for different run, is there any better way to avoid the dynamic sql in this situation?
I am trying my best, searching, asking and implementing different approaches etc, if anybody can give me some suggestion, link or even code snippet that would very helpful.
Hi,
I have a table (Table123) that has Columns ColA, ColB, ColC, ColD, ColE, ColF, ColG, I have many rows entered in the same table but want to check for two rows RowA, RowB, if for example I have three columns that are different in these two rows, I want to select those Column Names, like if ColA, ColC and ColE are changed then my query should return me as below
TableName, ChangedColumnName, OldValue, NewValue
Table123 , ColA, 123 Greetings 123 New Greetings
Table123 , ColC, 123 World 123 Hello World
Table123 , ColE, 123 Test World 123 New World
etc.
Is there anyway I can do it, but without using dynamic sql any help would be greatly helpful, thanks in advance.
Thanks in advance
Thanks,
Abdul Aleem

If you have only a few possibilities for the tables and they are known beforehand then you could do a simple case structure to decide the query.
But before you jump into solutions, few questions you should consider:
- Why do you want to avoid dynamic SQL? When done properly, it has it's place.
- Is the table name the only thing that varies in the queries. If it is, I would suggest reconsidering the structure of the database, because in such situation it sounds that the different tables could be replaced with a single table with proper categorizing fields.

- I saw Dynamic Sql is taking lot of time for execution, even if I use it with most possible ways when Data becomes little bit, the difference in execution time is too huge.
- No I saw now that I have use Columns as well randomly - is there any way like compare with sysColumns and then get its type then join with it etc? Anything works for me without using dynamic sql.
Thanks,

You lost me with the "three columns that are different in these two rows" - how can you have different columns in specific rows of a single table?
You've also mentioned that your dynamic SQL is taking a long time to run - I don't believe that is because it is dynamic SQL. It's more likely to be the way you have constructed the actual query.
If you share the code you use to build the dynamic query it might help me to understand what you are trying to achieve (and we might also be able to solve your performance problem)

Chilli is right, dynamic sql is unlikely to be your problem, query design is almost certainly the cause of slow processing.
You need to create a temp table that hold all the field from the various sources and feed the records into that table to make the structure the same.

Yeah Could be but most of the times I used Dynamic Sql if the rows are in like 10000s or 100000s then performance of the Stored Procedure decreased even after enabling and disabling the Query plans in both situations it decreased heavily, but I was able to bring that up 10 or 20 minutes, which is not bad for ETLs. But then the Politics involve and make us inferior just for that reason. That's what happens most of the times. But yes normal queries I ran so far run within couple of minutes but the dynamic sql took 10s or 20s of minutes and I could not able to minimize it more than that.
Any help would be greatly helpful - thanks for all help my friends.

Have you taken the script of the dynamic query and run a query profile on it to see if there are indexes that can be tuned.

As I said last week, if you share the code that you are using to generate the dynamic SQL we may be able to help you improve it

My task is: Our users get from their chemical suppliers some tables do determine the required quantity for chemical Y based on the given quantity of chemical X.
BTW: The task is_not_ to find a linear regression formula.
Easy example- 2 Dim: Depending on X the component Y has to be used with different quantities:
X Y= f(X)
1 0.1
2 0.2
3 0.5
In Praxis this will be not only y= f(x) it is more r=f(x,y,z, ...) and much more it is (r, s, t, ...)= f(x, y, z, ....) but the later is not the discussion here.
Now I'm asking me how one can design a General database layout with a constant number of tables/fields to save an N dimensional function.
With constant number of tables/fields I mean I don't like to solve this task by creating "dynamicly" columns according to the bigest dimension in use... or so 
Note: I have also to say most probably I’m not going to save this kind of data in a set of related tables, but anywhere I’m interesting how one would do it theoretically, maybe this gives me some more ideas and last but not least to learn.
The dimensions are usually around 3 to 5, but I like to solve: How can one design a General Database Table Layout -for N dimensions - for this task?
Is started like this
TBLS
ID (P)
NAME
TBLS_BASES
ID
TBLS_ID (P) FK: TBLS.ID
BASE_ID (P)
BASE_NAME
TBLS_BASES_VALUES
ID
TBLS_ID (P) FK: TBLS_BASES.TBLS_ID
TBLS_BASES_ID (P) FK: TBLS_BASES.BASE_ID
POS (P)
VALUE
TBL_VALUES
TBLS_ID FK: TBLS_BASES_VALUES.TBLS_ID
TBLS_BASES_ID FK: TBLS_BASES_VALUES.TBLS_BASES_ID
POS FK: TBLS_BASES_VALUES.POS
VALUE
Now an example for three dimension z= f(x, y)
First the three "base" tables for the function
TBLS TBLS_BASES TBLS_BASES_VALUES
====== ========================== ==========================================
ID BASE_ID TBLS_ID BASE_NAME TBLS_ID TBLS_BASES_ID POS VALUE
(P) (P) (P) (P) (P) (P)
---- ---- ------- --------- ------- ------------- --- -----
T1 T1B1 T1 e1 T1 T1B1 1 0.1
T1 T1B1 2 0.2
T1 T1B1 3 0.3
T1 T1B2 T1 e2 T1 T1B2 1 0.7
T1 T1B2 2 1.2
T1 T1B2 3 3.4
And here my Problem comes
In case of 3Dim always for 2 bases are needed to save one function value, in case if 4Dim it Needs a Group of 3 bases to save a function value, and so on...
Does any body has a sugestion for a better layout? At the moment I'm blocked and don't see a way how I can link a "Group" of items to one specific "Point".
TBL_VALUES
==========================================
TBLS_ID TBLS_BASES_ID POS VALUE
------- ------------- --- -----
T1 T1B1 1 1
T1 T1B2 1 1
T1 T1B1 1 2
T1 T1B2 2 2
T1 T1B1 1 3
T1 T1B2 3 3
T1 T1B1 2 4
T1 T1B2 1 4
T1 T1B1 2 5
T1 T1B2 2 5
T1 T1B1 2 6
T1 T1B2 3 6
T1 T1B1 3 7
T1 T1B2 1 7
T1 T1B1 3 8
T1 T1B2 2 8
T1 T1B1 3 9
T1 T1B2 3 9
Sorry for my english and thank you in advance for some tips.

[Edit]
Sorry for that, after about 2h edit I hope it is finally done, but preview does not really works nice 
Ok, it was not only preview

In your TBLS have a parent ID which is self referencing. I would also store a text structure of your formula in that table.
This is a straight forward bill of materials structural requirement.
Have you considered a mathematical formula parser it may allow you to store the text and decompose it to elements on the fly (caveat I have no idea of their capabilities or accuracy).
