Parameters With LIKE Statement
Aug 24, 2005
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?

Hi,
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'.
Has anyone seen this before?

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

Hei,I'm currently trying to write a program in C# that will allow users toparametrize their queries.For instance, I have a query like this:SELECT * FROM Customers Where Region = @Region AND Gender > @GenderHow can I extract the Parameters names without using Stringmanipulation (which is not perfect since sql statements can alsocontain '@' in LIKE clauses for example)I tried this wayDim 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?RegarsPhilippe Graca

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?
Thanks

Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
Dim pageID As StringpageID = Request.QueryString("ID")
TextBox13.Text = pageID 'Test to make sure the value was stored
SqlDataSource1.SelectParameters.Add("@pageID", pageID)
End Sub
....
<asp:SqlDataSource ID="SqlDataSource1" runat="server" ProviderName=System.Data.SqlClient ConnectionString="Data Source=.SQLEXPRESS;Initial Catalog=software;Integrated Security=True;User=something;Password=something" 'SelectCommand="SELECT * FROM Table1 WHERE [ClientID]='@pageID' ></asp:SqlDataSource>
The error that i am getting, regardless of what i put inside the ' ' is as follows:
"Conversion failed when converting the varchar value '@pageID' to data type int."
anyone have any suggestions ?

When I debug my code I see the string going into the parameter correclty, but the the delete statement doesnt work and I'm not sure why. Does this look ok? // Set up SqlCommand, connection to db, sql statement, etc.
SqlCommand DeleteCommand = new SqlCommand();
DeleteCommand.Connection = DBConnectionClass.myConnection;
DeleteCommand.CommandType = CommandType.Text;
// Store Primary Key photoID passed here from DeleteRows_Click
// in a parameter for DeleteCommand
SqlParameter DeletePrimaryKeyParam = new SqlParameter();
DeletePrimaryKeyParam.ParameterName = "@PhotoID";
DeletePrimaryKeyParam.Value = photoID.ToString();
// Insert new parameter into command object
DeleteCommand.Parameters.Add(DeletePrimaryKeyParam);
// Delete row, open connection, execute, close connection
DeleteCommand.CommandText = "Delete From Photo_TBL where PhotoID IN (@PhotoID)";
Response.Write(DeleteCommand.CommandText);
// DeleteCommand.Connection.Close();
DeleteCommand.Connection.Open();
DeleteCommand.ExecuteNonQuery();
DeleteCommand.Connection.Close();

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!

In an OLE DB Source in an SSIS package, we are having difficulties using multiple parameters in a SQL statement.
Using a single '?' works fine, but I've read that when you want to map more than 1 parameter you should use 'Parameter0, Parameter1, etc'.
The problem is that when we use Parameter0 and Parameter1 and then try to map it, it says that the query contains no parameters.
Can anyone help with the correct way to use multiple parameters in a SQL query that's part of an OLE DB Source task?
Thanks,
Mike

Hi to allI wish to be able to have a standard select statement which hasadditional fields added to it at run-time based on suppliedparameter(s).iedeclare @theTest1 nvarchar(10)set @theTest1='TRUE'declare @theTest2 nvarchar(10)set @theTest2='TRUE'selectp_full_nameif @theTest1='TRUE'BEGINother field1,ENDif @theTest2='TRUE'BEGINother field2ENDfrom dbo.tbl_GIS_personwhere record_id < 20I do not wish to use an IF statement to test the parameter for acondition and then repeat the entire select statement particularly asit is a UNIONed query for three different statementiedeclare @theTest1 nvarchar(10)set @theTest1='TRUE'declare @theTest2 nvarchar(10)set @theTest2='TRUE'if @theTest1='TRUE' AND @theTest2='TRUE'BEGINselectp_full_name,other field1,other field2from dbo.tbl_GIS_personwhere record_id < 20ENDif @theTest1='TRUE' AND @theTest2='FALSE'BEGINselectp_full_name,other field1from dbo.tbl_GIS_personwhere record_id < 20END......if @theTest<>'TRUE'BEGINselectp_full_namefrom dbo.tbl_GIS_personwhere record_id < 20ENDMake sense? So the select is standard in the most part but with smallvariations depending on the user's choice.

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
Thank you

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?
Thanks in advance.

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

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.
Regards,
Bill

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

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???

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,

I am currently having this problem with gridview and detailview. When I drag either onto the page and set my select statement to pick from one table and then update that data through the gridview (lets say), the update works perfectly. My problem is that the table I am pulling data from is mainly foreign keys. So in order to hide the number values of the foreign keys, I select the string value columns from the tables that contain the primary keys. I then use INNER JOIN in my SELECT so that I only get the data that pertains to the user I am looking to list and edit. I run the "test query" and everything I need shows up as I want it. I then go back to the gridview and change the fields which are foreign keys to templates. When I edit the templates I bind the field that contains the string value of the given foreign key to the template. This works great, because now the user will see string representation instead of the ID numbers that coinside with the string value. So I run my webpage and everything show up as I want it to, all the data is correct and I get no errors. I then click edit (as I have checked the "enable editing" box) and the gridview changes to edit mode. I make my changes and then select "update." When the page refreshes, and the gridview returns, the data is not updated and the original data is shown. I am sorry for so much typing, but I want to be as clear as possible with what I am doing. The only thing I can see being the issue is that when I setup my SELECT and FROM to contain fields from multiple tables, the UPDATE then does not work. When I remove all of my JOIN's and go back to foreign keys and one table the update works again. Below is what I have for my SQL statements:------------------------------------------------------------------------------------------------------------------------------------- SELECT:SELECT People.FirstName, People.LastName, People.FullName, People.PropertyID, People.InviteTypeID, People.RSVP, People.Wheelchair, Property.[House/Day Hab], InviteType.InviteTypeName FROM (InviteType INNER JOIN (Property INNER JOIN People ON Property.PropertyID = People.PropertyID) ON InviteType.InviteTypeID = People.InviteTypeID) WHERE (People.PersonID = ?)UPDATE:UPDATE [People] SET [FirstName] = ?, [LastName] = ?, [FullName] = ?, [PropertyID] = ?, [InviteTypeID] = ?, [RSVP] = ?, [Wheelchair] = ? WHERE [PersonID] = ? ---------------------------------------------------------------------------------------------------------------------------------------The only fields I want to update are in [People]. My WHERE is based on a control that I use to select a person from a drop down list. If I run the test query for the update while setting up my data source the query will update the record in the database. It is when I try to make the update from the gridview that the data is not changed. If anything is not clear please let me know and I will clarify as much as I can. This is my first project using ASP and working with databases so I am completely learning as I go. I took some database courses in college but I have never interacted with them with a web based front end. Any help will be greatly appreciated.Thank you in advance for any time, help, and/or advice you can give.Brian

Ok I have a query "SELECT ColumnNames FROM tbl1" let's say the values returned are "age,sex,race".
Now I want to be able to create an "update" statement like "UPATE tbl2 SET Col2 = age + sex + race" dynamically and execute this UPDATE statement. So, if the next select statement returns "age, sex, race, gender" then the script should create "UPDATE tbl2 SET Col2 = age + sex + race + gender" and execute it.

Hi guys,
I have the query below (running okay):
Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
FROM myTables
WHERE Conditions are true
ORDER BY Field01
The results are just as I need:
Field01 Field02
------------- ----------------------
192473 8461760
192474 22810
Because other reasons. I need to modify that query to:
Code Block
SELECT DISTINCT Field01 AS 'Field01', Field02 AS 'Field02'
INTO AuxiliaryTable
FROM myTables
WHERE Conditions are true
ORDER BY Field01
SELECT DISTINCT [Field02] FROM AuxTable
The the results are:
Field02
----------------------
22810
8461760
And what I need is (without showing any other field):
Field02
----------------------
8461760
22810
Is there any good suggestion?
Thanks in advance for any help,
Aldo.

I've have a need with SQL Server 2005 (so I've no MERGE statement), I have to merge 2 tables, the target table has 10 fields, the first 4 are the clustered index and primary key, the source table has the same fields and index.Since I can't use the MERGE statement (I'm in SQL 2005) I have to make a double step operation, and INSERT and an UPDATE, I can't figure how to design the WHERE condition for the insert statement.

i was tasked to created an UPDATE statement for 6 tables , i would like to update 4 columns within the 6 tables , they all contains the same column names. the table gets its information from the source table, however the data that is transferd to the 6 tables are sometimes incorrect , i need to write a UPDATE statement that will automatically correct the data. the Update statement should also contact a where clause
the columns are [No] , [Salesperson Code], [Country Code] and [Country Name]
i was thinking of doing
Update [tablename]
SET [No] =
CASE
WHEN [No] ='AF01' THEN 'Country Code' = 'ZA7' AND 'Country Name' = 'South Africa'
ELSE 'Null'
END
What is the best way to script this
