This may sound a bit weird...
But I need to find the data that does not match between two tables.
I'm using MySql
Suggestions are welcome
Thanks in advance.

If you are using SQL 2005, use the EXCEPT operator to find differences between entities.

Sorry, forgot to mention...
I'm using MySql...
I tried using NOT IN but it returns empty...

What code have you tried?

Something like this...
Search from tableA where id NOT IN (search id that match between tableB and tableA)
|
|
|
|
|
Assuming that you are working with Sql Server, you may try
Select A.[ColumnName],B.[ColumnName2] from table1 A,table2 B
where A.[PKColumn] <> B.[FKColumn]

Hi,
Say I have the table below:
Tabl1
PKey ColA ColB ColC
1 a1 b1 c1
2 a1 b2 c2
3 a1 b3 c3
... a2 ...
...
... a3 ...
...
If I group by ColA with the select statement as follows:
SELECT<br />
ColA, MAX(ColB), <br />
FROM<br />
Tabl1<br />
GROUP BY<br />
ColA
If for example for a1 the MAX(ColB) is b2, THEN I would like to include ColC in the select statement such that for a1 the resulting row would be:
ColA ColB ColC
a1 b2 c2
What is the best way to do this?
TIA!
I am a SysAdmin, I battle my own daemons.

select b.*
from (
select ColA, Max(ColB) as MaxColB
from Tabl1
group by ColA
) as a
Tabl1 as b
on b.ColA = a.ColA
and b.ColB = a.ColB
order by b.ColA

Use the T-SQL REPLACE function to remove the literal string 'Record:' from your text.
Is it actually necessary to store the string 'Record:' in each record value? What purpose does it serve? It looks like your database design may be broken and could do with normalization.

Don't double-post. It's rude.
Anyway, why did you think it was a good idea to post your question in the SQL forum. Your question has nothing to do with SQL. Next time, I suggest you engage your brain and think for 5 seconds before you post.

Do NOT post the same question in multiple forums. Doing so is considered very rude around here and on other sites as well. And, as you've found out, it doesn't get your question answered any faster.
BTW, what does this have to do with SQL??

Hi people.This is Amitav Guha From Bangladesh.
How can i deploy a SQL database after designing it?
Can anyone plse answer me.

You could backup the database on your development server and restore it to your production server.
Alternatively, generate scripts for your database from Management Studio, copy and run them on your production server.

I figured this out! I has to do with that the web app is logging in using sql authentication and I wasn't.
I have an issue and I don't really know how to put it in words in order to put it in a search engine and hope to get an answer, so I will tell you my problem and I hope you can help me.
My software accesses a SQl Server database using the connection string
("Data Source=.\SQLEXPRESS;AttachDbFilename=" + txtbxdatabase.Text + ";Integrated Security=True;Connect Timeout=30;User Instance=True") (I go the sintax from the connection string created from wizard)
As you can see it gets the name of the database from a text box. This works perfectly until we try to use our software with a third party vender's software.
Third Party software uses ASP to connect to the Sqlserver on station (PC) and writes transaction data to it. When my program tries to open the same Sqlserver on the station (PC) it gets an error (I did not write it down) that, in so many words, would not let my program access the database because it is already in use. I think my connection string is the problem, but I have not found anything helpful online.
Any ideas?

n my C# program, I get the following error when trying to write to a
table:
"Dynamic SQL generation for the UpdateCommand is not supported against
a SelectCommand that does not return any key column information."
i use this code :
da = new OracleDataAdapter(command, con);
da.MissingSchemaAction = MissingSchemaAction.AddWithKey;
comB = new OracleCommandBuilder(da);
da.Fill(ds, "product");
ds.Tables["product"].PrimaryKey = new System.Data.DataColumn[] { ds.Tables["product"].Columns["item_code"] };
comB.GetUpdateCommand();
da.Update(ds, "product");

Hi Sujit!
Do you have a primary column defined in the Table? If not then defined it.
You must have a primary key defined in your database tables to avoid this error.
I hope this will help you.
Regards.

Apply a sort so that the last entered records are output first.
