Is this possible/how is it done?
I tried just going through and putting a @DBName.dbo.Table1
in the FROM clause but it said invalid object name @DBName ...
I also tried this in a stored proc, but it didn't work either:
quote:
EXEC('USE ' + @DBName)
*SELECT STATEMENT HERE*
Any suggestions?
Is there any way to use a parameter as a databas or tabel name? I like to use a parameter where I now use "PulpQMain" I like to read the database name from a tabel in runtime so the sp works even if a change name on the database.
Thanks /Jörgen

View 1 Replies View RelatedHi, i have a big problem. I´m having trouble with the select statement in SQL query language. The problem is that I need to retrieve various data from database and the input object is a list. The simple way of doing this is:SELECT <return values>FROM <datatable name>WHERE (<select data parameter>)My problem is that my where parameter needs to be an array list. The simple way of solving the problem would be using a for statement in my c# code and call my store procedure various times, but my array list can be too long and take a long time to connect and search data for each statement, so I need to access the database once.Can anybody help; I would appreciate it very much thx, Malcolm
Hi all,
I am trying to create a report against an Access 2003 database using the provider as follows: "Provider=Microsoft.Jet.OLEDB.4.0;"
Simple reports with no parameters are fine (e.g. using a text query of 'Select * from BERs'
But how do I pass in a report parameter to limit the results coming back ? I have only used stored procs in the past which work fine but how to achieved this using Access has me stumped.
An example query I need would be 'Select * from BERs WHERE Year = [Year?]'
Anyone got any pointers ?
Thanks in advance

I have reportviewer control into the aspx page and i want to save the parameters informations to the database. but i also want to stick with reportviewer parameter UI instead of my own UI.
Is that possible using ReportViewer?

Hallo
is it possible to perform an insert/update query upon the execution of a report, using the report Visual Basic expressions?
I mean, the user enters some values for the report parameters, and i would like to store them, along with the resulting recordset data, into a dedicated table in the database.
I was curious to know if it the amount of data sent to the sql server mattered.
I am working on a web application and I have three stored procedures that most likely will be called one after the other. Each procedure accepts at least 4 parameters. Instead if I create one stored procedure, then I will be passing at least 12 parameters. Some of the parameters could be quite bulky(at least 1000 characters).
So which one is better, 1 stored procedure with 12 parameters or 3 stored procedures with 4 parameters each called one after the other.
Thanks

View 2 Replies View RelatedIn many DTS packages I have used parameterised queries for incremental loads from Oracle database sources using the Microsoft ODBC Driver for Oracle.
Now I want to migrate these packages to SSIS, but the OLE DB connection for Oracle does not support parameters.
I cannot use the "SQL command from variable" data access mode because of the 4000 character limitation on the length of string variables and expressions.
Am I missing an obvious workaround?
I have setup a Database Audit Specification as follows:
Audit Action Type: SELECT | Object Class: DATABASE | Object Name: SHOPDB | Principal Name: public
Now, when I perform a SELECT query with a bound parameter such as:
SELECT * FROM myTable WHERE name='queryname'
What I see through the Audit Logs is something like:
SELECT * FROM myTable WHERE name='@1'
I understand that it is by design that we cannot see these parameters throught Database Level Auditing. I would like to know whether it is possible to see these parameters by any other means using
(1) SQL Server Enterprise Edition,
(2) SQL Server Standard Edition, or
(3) by an external tool.
In the v1.2 CTP version, the DatabaseMetadata methods for getting information about objects in a database (i.e. getTables(), getColumns(), ...) errors if your current database connection is in a different database than the object you are quering.
Is this the intended behavior going forward?
In my case I have access to both database A and database B. My current connection is in database A , but I am looking up object in database B.
ResultSet rs = conn.getDatabaseMetadata.getTables("B","dbo","%",{"TABLES" });

I have a SSRS report with four parameters,and I want to be able to enter information for two of the parameters and run the report opposed to all four of them. However, when I select allow blanks and only select the parameters that I want to run the report by, the report come back blank..Essentially, I want to be able to the run report by different parameters without having to enter information for all parameters at the same time.
View 2 Replies View RelatedHi,
I have an app in C# that executes a query using SQLCommand and parameters and is taking too much time to execute.
I open a SQLProfiler and this is what I have :
exec sp_executesql N' SELECT TranDateTime ... WHERE CustomerId = @CustomerId',
N'@CustomerId nvarchar(4000)', @CustomerId = N'11111
I ran the same query directly from Query Analyzer and take the same amount of time to execute (about 8 seconds)
I decided to take the parameters out and concatenate the value and it takes less than 2 second to execute.
Here it comes the first question...
Why does using parameters takes way too much time more than not using parameters?
Then, I decided to move the query to a Stored Procedure and it executes in a snap too.
The only problem I have using a SP is that the query can receive more than 1 parameter and up to 5 parameters, which is easy to build in the application but not in the SP
I usually do it something like
(@CustomerId is null or CustomerId = @CustomerId) but it generate a table scan and with a table with a few mills of records is not a good idea to have such scan.
Is there a way to handle "dynamic parameters" in a efficient way???
Hello:
I just recently bumped into this problem and I think I know what's causing it. This is the setup:
Report Parameters: FromDate, ToDate, DivisionalOffice, Manager, SalesRep
dsCalendarEvents Parameters: FromDate.Value, ToDate.Value, DivisionalOffice.Value,
dsDivisions Parameters: N/A
dsManager Parameters: DivisionalOffice.Value
dsSalesRep: DivisionalOffice.Label
When I query the ReportServices WS and scan the parameter dependencies for SalesRep it says there are four dependencies: FromDate, ToDate, DivisionalOffice and Manager!!!
If I change "dsSalesRep" to use "DivisionalOffice.Value" the ReportingServices WS parameter dependency scan returns only one dependency for "SalesRep" parameter!!!( This is the correct behavior )
Has anybody seen this behavior and more importantly, is there a work around?

Hello all,
Given:
string commandText = "Categories_Delete";SqlCommand myCommand = new SqlCommand(commandText, connection);myCommand.CommandType = CommandType.StoredProcedure;
Is there a reason NOT to use myCommand.Parameters.AddWithValue("@CategoryID",CategoryID); I'd prefer to use that over myCommand.Parameters.Add("@CategoryID", SqlDbType.Int, 4).Value = CategoryID; as I have these functions being created dynamically and hope to get away from a big lookup to try to convert System.Types into SqlDbTypes. [shudder]
It seems that ADO.NET makes an implicit conversion to the valid type. If this is correct then I can move on fat dumb and happy. Anyone have any good insight?
Thanks,

Hi,
I'm having a bit of trouble with SQL Parameters. I can't seem to define the type when creating the parameters.
Here's what I've done:
I have a function that processes my request and returns a datatable:
Public Function Grab_Data(querystring asn string, params() as SqlParameter) as DataTable
... dims all the necessary variables
Try
...creates the connection and command
Dim p as SqlParameter
For each p in params
p = command.parameters.add(p)
p.direction = parameterdirection.input
Next
...opens connection, creates dataset and fills it
Finall
....disposes connection and command
End Try
Return datatable
End Function
I call this function by:
...dim the necessary variables
querystring = "SELECT * FROM Tbl_Users WHERE Joined>=@date"
dataTable = Grab_Data(querystring, New SQLParameter("@date", DateTime.Today))
My code works fine and I get the results that I want, but no where in my code is the type of the parameter defined.
I tried calling the function like:
Grab_Data(querystring, New SQLParameter("@date", SQLDBType.DateTime, DateTime.Today))
But when I do this, I get an error saying that no value is assigned to @date.
Can anyone tell me what I need to modify so that I can pass the type of the parameter to the function?
The reason why I am not explicity defining the parameters in the function is because I can reusing the function numerous times throughout my code. So some calls have three parameters passed to it and some and none.
Thanks.

where customers.name request.form("txtoperator") request.form("txtname")

Hi all, I am using classic ASP and SQL Server 2005. Can I use parameters like @whatever in my asp code or are they for stored procedures exclusively?

However, when I run dbo.skillsearch 'ph%'
I get an empty set, while dbo.skillsearch 'php' returns the results expected.
I am therefore assuming that I can't use a parameter for a LIKE clause with any wildcards?
Is there any way around this other than manually building the SQL statement in the SP and then executing it? I'd obviously prefer to not have to do it that way for all the SQL Injections and related reasons.
Wouldn't this also kill my query optimization benefits, manually building the statement each time?

I am trying to use the URL to pass a parameter to a report. I have tried several ways to make this happen with no effect. My report is using a sproc that has a int parameter. I have tried make a list of partial parameters and passing the parameter I want through the URL. I hide the prompt. I put NULLs and Blanks allowed. I have created a linked report then hid the prompt. I used parameters=false instruction. Here is the basic URL http://reportsrv/Reports/Pages/Report.aspx?ItemPath=%2fActiveTasks%2fProject+Details&rs:Command=Render&ProjectID=56.
Please Help it is driving me crazy.

View 1 Replies View RelatedI have a table of 25-30 million properties, from which are retrieved~150 centered on a point, based on the parameters -- coordinates,property type and date of transaction. There's an SP (also implementedas a function returning a table) to return the desired records.This look-up takes the most time in the C# program that calls it, andshould be optimized. It was suggested that instead of having an SP onthe server, each time the program should create an SP that is the same,however without any parameters -- with the values hard-coded. Thenexecute it, and drop it. This way, the execution plan will becustomized for the specific parameters. I tried it and it turns outthe suggested method is noticeably faster, even compared to recompilingan SP every time. I was wondering if there is a way to get equivalentperformance out of an SP or UDF that has parameters, or is thisapproach necessarily going to be less optimized than hard-codednon-parameters.Thanks,Jim
