Hi to all
select ModelName from SRO_ModelMaster
select RegionCode from cmp_RegionMaster
SELECT Count(*) as 'TOT' FROM SRO_SurveySelectedModel,cmp_RegionMaster WHERE
modelno in (Select ModelNo From SRO_ModelMaster where ModelName='FNRO')
AND approved='Y' AND RosapCode in (
SELECT ROsapCode FROM SRO_ROMaster where region='ER')
Please tell me how i can combine these three statments into Single SQL
Statment
I want to develop Stored procedure From this without using temp table
Thanks & regard

Basically you need to join those tables and then group by ModelName and RegionCode but to get this statement further: what is the relationship between those four tables?
Your query should look something like:
SELECT SRO_ModelMaster.ModelName,
cmp_RegionMaster.RegionCode,
Count(*) as 'TOT'
FROM SRO_SurveySelectedModel,
cmp_RegionMaster,
SRO_ModelMaster,
SRO_ROMaster
WHERE ???.modelno = SRO_ModelMaster.ModelNo
AND SRO_ModelMaster.ModelName='FNRO'
AND ???.approved='Y'
AND ???.RosapCode = SRO_ROMaster.ROsapCode
AND SRO_ROMaster.region='ER'
AND SRO_ROMaster.??? = ???.???
GROUP BY SRO_ModelMaster.ModelName,
cmp_RegionMaster.RegionCode

Hello All,
I am getting this error "Conversion failed to when converting datetime string to smalldatetime data type" in Sql Server 2008 and my string is 20081110072938 .....I also tried with datetime data type in Sql server but same error.
Exception comes at query
sql.Format("Insert into trade values('%s','%s','%s','%s','%s','%ld')",
m_sTimeStamp,m_sTradeStatus, m_sTradeType, m_sTradeXML, m_sTradeKcc, m_nTrdNumber);
here m_sTimeStamp has the value 20081110072938 .
query is like
insert into trade values('20081110072938','yes','Regular','xml','kcc','1');
first column is of datetime type.. it gives the conversion error in SQL Server 2008 .
.. whereas same string is getting converted to datetime format in MySQL ... and working fine with MySQL...
I am doing all this in VC++.
Can anybody help me out of this...
Thanks

insert into trade values('20081110072938','yes','Regular','xml','kcc','1');
To

So are you still having problems with this?
Each database server typically has a different 'native' format for dates and times. The easiest (and a correct) way to overcome this is to use parameters for operations instead of literal values. For example if you're using OdbcConnection, you should use OdbcParameter class to define values for the operations.
If you still need to use literal, perhaps you could use native conversion functions such as CONVERT or CAST in SQL Server.

Can you simply save it as a text file and then use source command in mysql command line client?
List of all MySQL commands:
Note that all text commands must be first on line and end with ';'
? (\?) Synonym for `help'.
clear (\c) Clear command.
connect (\r) Reconnect to the server. Optional arguments are db and host.
delimiter (\d) Set statement delimiter. NOTE: Takes the rest of the line as new delimiter.
ego (\G) Send command to mysql server, display result vertically.
exit (\q) Exit mysql. Same as quit.
go (\g) Send command to mysql server.
help (\h) Display this help.
notee (\t) Don't write into outfile.
print (\p) Print current command.
prompt (\R) Change your mysql prompt.
quit (\q) Quit mysql.
rehash (\#) Rebuild completion hash.
source (\.) Execute an SQL script file. Takes a file name as an argument.
status (\s) Get status information from the server.
tee (\T) Set outfile [to_outfile]. Append everything into given outfile.
use (\u) Use another database. Takes database name as argument.
charset (\C) Switch to another charset. Might be needed for processing binlog with multi-byte charsets.
warnings (\W) Show warnings after every statement.
nowarning (\w) Don't show warnings after every statement.

in joining the data in a certain in the database.. but how can i join this data using combo box?? can someone help me..
|
|
|
|

If anybody could undertsand what you are a talking about, probably we could. SQL doesn't have combo boxes, so I guess you are looking to filter the data in your code somewhere.

Hi all,
I've developed an application that's using SQL Server for DB, now I want to create a setup and give it to users.
For the DB part, I have a simple '.mdf' file that is my DB and working with that like this:
sql_conn = new SqlConnection(@"AttachDBFilename=c:\test.mdf;Integrated Security=true");
then it's a simple connection, but I don't know how to use my DB in the user's computer, I should only copy the .mdf file in the user's computer? what's the exact steps to deploy a SQL DB related application?
I've searched the Internet and some eBooks + MSDN but didn't find anything about that.
Please answer soon, since I want that in a week.
Thanks in advance.

Thanks that was good,
but I'm using SQL Server 2005, how can I deploy the DB? What the user that wants to use my app should have so that my app can run properly? is the SQL Express should be installed? Please guide me on this! 
|
|
|
|
|
Are you using SQL Server 2005 Express Edition or Compact Edition?
Express Edition needs to be installed before it can be used, but Compact Edition is basically working on .Net framework so if .Net framework is installed on the client you already have all the dll's.
If you're using Express Edition, this should help you forward: Embedding SQL Server Express into Custom Applications[^].

ADO.NET offers a great functionality which makes it very easy to implement databinding (two directional - read and write). Let`s assume that we have a DataSet with some simple DataTable tied with TableAdapter.
Here is what we have to do:
1) Create DataTable with the standard GetData method from the Adapter
2) Assign this datatable as binding source for our datagridview on UI
3) When user makes some changes in the datagridview, it is enough to call 'Update' method on the Adapter to transfer all changes into database.
This is very easy and fast to implement. However it does not work when our DataTable contains data from more than 1 physical tables from database (any joins in select clause).
Why is it impossible? The update method on tableAdapter does not generate at all. How to solve this?
Thank you very much for any help!

Haven't really used TableAdapter so I'm not able to say why it's not genereting all the methods (my guess is that the generator thinks that the view isn't updatable).
On the server side there are strict rules when the view can be updated:
- Any modifications, including UPDATE, INSERT, and DELETE statements, must reference columns from only one base table.
- The columns being modified in the view must directly reference the underlying data in the table columns. The columns cannot be derived in any other way, such as through the following:
- An aggregate function: AVG, COUNT, SUM, MIN, MAX, GROUPING, STDEV, STDEVP, VAR, and VARP.
- A computation. The column cannot be computed from an expression that uses other columns. Columns that are formed by using the set operators UNION, UNION ALL, CROSSJOIN, EXCEPT, and INTERSECT amount to a computation and are also not updatable.
- The columns being modified are not affected by GROUP BY, HAVING, or DISTINCT clauses.
- TOP is not used anywhere in the select_statement of the view together with the WITH CHECK OPTION clause.
So you may have to use VIEW_METADATA option on the view or INSTEAD OF triggers.
Hope this helps,
Mika

I guess the table adapter will have some UpdateCommand property that you need to manually set.
Hope that helps.

my question is that:
i have EMP table and also EMP_TRACK table.....suppose if im going to update EMP table the no.of rows gets effected should be stored in EMP_TRACK table.
that means EMP table simply contains columns EMPNO,ENAME.
whereas EMP_TRACK table contains columns DMLTYPE and NO_OF_ROWS_EFFECTED.
|
|
|
|
|
One way is to build a trigger on EMP and select count from inserted or deleted virtual tables.
Another way could be that you get the number of rows affected at client side and then insert it to emp_track.
One link that could be useful: Using the inserted and deleted Tables[^]
