Hei,
I'm currently trying to write a program in C# that will allow users to
parametrize their queries.
For instance, I have a query like this:
SELECT * FROM Customers Where Region = @Region AND Gender > @Gender
How can I extract the Parameters names without using String
manipulation (which is not perfect since sql statements can also
contain '@' in LIKE clauses for example)
I tried this way
Dim comm As New OleDbCommand(SqlStatement, myCon)
comm.Prepare()
MsgBox(comm.Parameters.Count.ToString())
comm.Dispose()
myCon.Close()
but this always return me 0 (zero)
Do you have any idea on how to solve this generic problem?

I am stuck on how to syntactically retrieve an output value (@ProdCount) from a stored procedure. The SPROC works fine: the value of @ProdCount appears correctly in the output window. However, I can't retrieve it in the DAL handler (value remains 0). Does anyone have an idea on how to properly extract the return value. TIA for any pointers.SPROC (abridged): ALTER PROCEDURE and_Store_GetProductsByProdCatID_SortPage (@ProdCatID INT,...@ProdCount INT OUTPUT )
ASSELECT @ProdCount=(SELECT COUNT(*) FROM and_StoreProduct WHERE ProdCatID= @ProdCatID)DECLARE @SQL nvarchar(4000)SET @SQL = 'WITH tmpProd AS ( SELECT ROW_NUMBER() etc.. )SELECT ProdID, etc..FROM tmpProdWHERE Row BETWEEN etc..ORDER BY etc..'

"Current Date updated ( 12/31/2015 -> 12/31/2016 )" "Status updated ( Open -> Should be Closed )" From example 1 ==> need outputs of " 12/13/2015" and "12/31/2016"; example 2 --> need outputs of "Open" and "Should be Closed"
These are what all records look like:
1. It contains the word, "updated". 2. There is a space after the last character of updated. Then, there is a space before open parenthesis. Then, there is a space before getting the required word. Example: "updated ( xxxxx" (xxxxx is a required extract word.) 3. The entire word(s) should be captured before the "->" sign (after the open parenthesis) 4. The last part is to captured everything after the "->" but before the close parenthesis ")"
Is there a way in SQL Server 2000 to extract data from a table, such thatthe result is a text file in the format of "Insert Into..." statements, i.e.if the table has 5 rows, the result would be 5 lines of :insert into Table ([field1], [field2], .... VALUES a,b,c)insert into Table ([field1], [field2], .... VALUES d, e, f)insert into Table ([field1], [field2], .... VALUES g, h, i)insert into Table ([field1], [field2], .... VALUES j, k, l)insert into Table ([field1], [field2], .... VALUES m, n, o)Thanks in advance
Suppose I have a table with relations (REL). In this table there are relations between parent en child, so the columns are: Rel_Id, parent_Id, child_Id. Example:
1, A, B 2, A, C 3, A, D 4, B, E 5, C, F 6, G, H 7, G, I 8, H, J
I need a query which returns all relations from REL that are in the same tree as the input unit. In the example, giving D as input unit, it should return relations 1, 2, 3, 4 and 5, because A, B, C, E and F are (in)directly related to D and belong therefore to the same tree. Giving H as input, it should return relations 6, 7 and 8. (with a tree, I mean that a parent can have 0, 1 or more children and a child belongs at most one parent.)
I have a sql that I want to execute with LIKE and parameters:I tried several options outlined that I found at http://aspnet101.com/aspnet101/tutorials.aspx?id=10%20but they all seem to return 0 records. When I try and execute my statement in Enterprise manager, it works fine.Code Snippet:...Dim sql as stringsql = "SELECT * FROM tblName WHERE First LIKE '%' + @fname + '%' AND Last LIKE '%' + @lname + '%'"Dim param(1) as sqlParametersqlParams(0) = New SqlParameter("@fname", SqlDbType.VarChar, 50)sqlParams(0).Value = Trim(fname.text)sqlParams(1) = New SqlParameter("@lname", SqlDbType.VarChar, 50)sqlParams(1).Value = Trim(lname.text)...Can anyone tell me if there is anything wrong with my code above?
I have an issue with an OLE DB command and parameters. The statement I want to run starts with a WITH statement - when I take out the parameter it runs fine. When I take out the WITH statement and leave the parameter in it runs fine. When I run the statement in SSMS it runs fine.
With both the WITH statement and the parameter in it gives the error 'Syntax error, permission violation, or other nonspecific error'.
The SQL for a dataset in ASP.NET 2.0 is as follows.... SELECT DISTINCT StudentData.StudentDataKeyFROM Student2Roster INNER JOIN StudentData ON Student2Roster.StudentDataRecID = StudentData.StudentDataRecIDWHERE (Student2Roster.ClassRosterRecID IN (@ClassRosterRecIDs) ClassRosterRecIDs are giuds At design time i use 'b2cf594d-908b-4c0c-a67f-6364899a4d42', '2e0b3472-d3f0-4a54-94af-bfc0a99525d9' as the parameter and it works in the designer but not at runtime. At runtime I get the error Conversion failed when converting from a character string to uniqueidentifier. If I leave the quotes off and only use 1 value like b2cf594d-908b-4c0c-a67f-6364899a4d42 it works.How can I use multiple guids as an IN parameter like 'b2cf594d-908b-4c0c-a67f-6364899a4d42', '2e0b3472-d3f0-4a54-94af-bfc0a99525d9'? Thanks
I have a report that is using a union statement to pull in data from two identical tables except that one is for current month, the other for archived data.
What I want to do is prompt the user once for a date and use the value to select from the right table. Since a sales date can only exist in one of the tables, one union will work, the other not.
But the report in prompting me for a parameter for each query....which is in Informix and the prompt is this: "?"
Is there anyway to force both halves of the query to see this as one parameter so the user is only prompted once?

Hi there, I am trying to use the ADO technology within MS Access 2000. Basically I'd like to use parameters in a command object to insert a new record and get its newly inserted ID. But instead of it it returns error:
Run-time error '-2147217900 (80040e14) Must declare the scalar variable "@ii_file"
Isn't this varaible (and all the rest of variables) declared by setting a parameter ".Parameters.Append .CreateParameter("@ii_file", adVarChar, adParamInput, 255, Me.cbo_ii) "? I'd like to avoid using stored procedures in order to create the whole SQL statement from the client side. Thanks!

Is there a way to retreive the SQL Statement with the values from the parameters merged together? I know how to retreive the SQL Select Statement and the parameters separately but I need to retreive the final SQL. For example: SELECT name FROM employee WHERE id = @id I would like to retreive from SQLDataSource SELECT name FROM employee WHERE id = 1
I have a user login scenario where I would like to make sure that they not only exist in the user table, but also make sure there account is "verified" and "active". I'm trying to return 3 output parameters. UserID, verified, active. Is this possible?
Do I need just a select statement to do this? What is the difference between the output and select statements?
I need to run a different select statement based on the value of a parameter. Visual studio is not liking how I am formatting it.

I am having trouble returning the correct record with my stored procedure. my problem is that i don't know how to structure the sql statement to do the following: given a set of records that have the same loankey, i need to 1. find the record that has most recent date (lockExprDt) 2. for all records with that date, find the highest Lock Number (LockNo) 3. for the all the records with that date and that LockNo, find the highest extension number (Ext) currently my sql statement returns a record that has the most recent date. i don't now how to write the sql to further define my query to return the record that has the most recent date with highest lock number, and finally the highest extension number. any suggestions as to what i am doing wrong. below is my slq statement. please note that i need to add the sql that will query for the max LockNo, and max Ext. Any help is greatly appreciated. thx! select a.loankey, a.lockrate, a.investor, a.price, a.ext, a.cost, a.lockno, a.lockstatus , CASE WHEN CONVERT(CHAR(8),a.lockdate,10)='12:00:00 AM' THEN NULL ELSE CONVERT(CHAR(8),a.lockdate,10) END as 'LockDate' , CASE WHEN CONVERT(CHAR(8),b.lockExprDt,10)='12:00:00 AM' THEN NULL ELSE CONVERT(CHAR(8),b.lockExprDt,10) END as 'LockExprDt' , Case WHEN CONVERT(CHAR(8),b.lockExprDt,10)>= CONVERT(CHAR(8),GETDATE(),10) THEN datediff(day, CONVERT(CHAR(8),GETDATE(),10), CONVERT(CHAR(8),b.lockExprDt,10)) ELSE NULL END as 'Days' from cfcdb..locktable ainner join (select loankey, max(lockExprDt) as lockExprDtfrom cfcdb..locktablegroup by loankey) bON a.loankey = b.loankey AND a.lockExprDt = b.lockExprDt where a.loankey = @LoanKey
I have a table which has a field called Org. This field can be segmented from one to five segments based on a user defined delimiter and user defined segment length. Another table contains one row of data with the user defined delimiter and the start and length of each segment. e.g.
Table 1
Org
aaa:aaa:aa
aaa:aaa:ab
aaa:aab:aa
Table 2
delim
Seg1Start
Seg1Len
Seg2Start
Seg2Len
Seg3Start
Seg3Len
:
1
3
5
3
9
2
My objective is to use SSIS and derive three columns from the one column in Table 1 based on the positions defined in Table 2. Table 2 is a single row table. I thought perhaps I could use the substring function and nest the select statement in place of the parameters in the derived column data flow. I don't seem to be able to get this to work.
Any ideas? Can this be done in SSIS?
I'd really appreciate any insight that anyone might have.
Hello, Is there any way to run a parameterized statement against SQL when you have an unknown ammount of inputs. Instead of doing the following: FOR i as integer = 0 to topValuestrWhere &= " OR myColName='"& myArr(i) &"'" NEXT wash up the string and submit this to SQL, I want to do it with parameters. I'm calling a sproc in SQL and I would prefer just to send in a string like "1,4,42',45" in a parameter split that in SQL and run my query.The query would be something like "...WHERE myColname=1 OR myColname=2 OR myColName=3" I only want to declare one parameter and not use string concatenation as described above.It doesn't matter if there's a split function in SQL or not, as long as it solves my problem in an efficient manner. Cheers!/Eskil

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.
Hi, 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???
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?
I have a table that has the first name and last name together in one field (stupid I know). I want to extract the first name from the field and copy it into another field names, well, firstname. I figure it might be possible since there is a comma after the last name. But how can I do this?
So for:
STRNAME ------------- adams, john ------------- washington, michael -------------
I want it to be like this
STRNAME | STRFIRSTNAME --------------------------- adams | john --------------------------- washington | michael
So I guess there would be two parts to the statement:
1. First I need to select or trim the strname field to the comma. BUT I don't want to just trim it- I want to copy it.
2. The next thing I need to do is to copy the lastname (the part that I trimmed) into a new field which I created called lastname.
I posted this a while ago with no luck and I'm going to try it again:
I have a column called strlastname with contains the firstname and last name of a client. I want to separate out the first name and last name into into two separate fields. I figured maybe I can do it easier if I copied the column into the table. So now I have a column called strfirstname that contains the first name and the last name and a colmn called strlastname that contains the first name and last name. The lastname is seperated from the first name with a comma like this:
