I'm creating a data flow task to export a set of records that were created within a specific time frame. The date offsets I'm using are read into user variables that are of type Int32. I have an OLEDB source connected to a SQL Server 2005 database using the following query to get the records I want:
select * from claim where date_created > dateadd(day,?,getdate)
I've mapped Parameter0 to my offset variable, which has a value of -7. When I hit OK to close out of the OLE DB Source editor, I get a message saying "Argument data type datetime is invalid for argument 2 of dateadd function." I can't figure out why it keeps talling me this even though the variable I'm passing in is an integer, not a datetime. I've done a lot of searching and found some instances of other people having this problem, but so far no answers. I could just go ahead and try to create an equivalent query using datediff or something, but I'd like to know what's going on here. Is this a bug in Integration Services itself, or is there another explanation?
Heres My SQL to get me 2 hours back of Midnight, two months ago (so 11pm of the prev day)
SELECT DATEADD("hh",-2,DATEADD("m",-2,DATEADD(dd,-(DAY(GetDate())-1),DATEADD(day,DATEDIFF(day, 0, GETDATE()),0)))) So I converted it into RS for my report start date, but it's not running...cant even get preview to load, it detects an error right away.,,just doesnt tell me what it is
I'm pretty sure I have the "h", "m" and "d" syntax right, I tried them all individually and they give me the correct dates...other than changing GetDate() to Now() I dont know what makes this diffenent...is it just too much nesting to Reporting Services?
Hello...I am running into a problem while running a query..can some1 help..this is the query :**************SELECT *from Table Swhere S.dtDate1 BETWEEN dateadd(year,1,dateadd(month,-1,getdate()))AND dateadd(day,-1,(dateadd(month,1,dateadd(year,1,dateadd(month,-1,getdate())))))***************(first part of the date calculation comes out to be '2005-05-01' andsecond part is '2005-05-31')Here is the interesting twist:The query runs right if the first date in the between clause isentered directly i.e. the query wud run right if i rite it asSELECT *from vCustomerProductDetail Swhere S.dtDate1 BETWEEN '2005-05-01'AND dateadd(day,-1,(dateadd(month,1,dateadd(year,1,dateadd(month,-1,getdate())))))The funny part is the ending date in the between part is depending onthe starting date if u notice..so if there is somethg rong in thefirst part there shud be somethg rong with the second too if u get wati am saying but the query runs right with the second part left as itis..can some1 please help..thanks-Raghu
I created a function to use in a View, works similar to DATEADD but only with my company's Business days Monday-Thursday.
I am running a query but it never ends to run.
This is the function:

[Code] ...
This is how I am trying to use it in the View:
Production.GBDATEADD(Production.Schedule.START_DATE, Production.Operations_Data_Pool.MFG_DAY - 1) AS SCH_DATE

Variables are only allowed when ordering by an expression referencing a column name. Are parameters not good for names of things in a query but ok for values of what those names represent? If not, what am I doing wrong? Thank you very much.
I am new to Parameterize query ... and i want to use above for inserting XML data and to retrive the same as it contains some special character so by using string it is changed.
I'm trying to return a query based on the dateadd function. I have a column in the database called date_added which is am successfully using the the DATEADD function above as date1. The Var1 variable I need to populate from the database too from a column called life_span which is an int data type. The error I get is An expression of non-boolean type specified in context where a condition is expected near select
My query is as follows: select guid, dateadd(day,life_span,date_added) as datepayday. From User_table

Hi, Below are two methods o passing a parameterized query, are these the same, or is one open to sql injection attacks more than the other?Option 1 - through code behindDim testDataSource As New SqlDataSource()testDataSource.ConnectionString = ConfigurationManager.ConnectionStrings("ConnectionStringName").ToString()testDataSource.UpdateCommandType = SqlDataSourceCommandType.TexttestDataSource.InsertCommand = "INSERT INTO test(id) VALUES (@id1)"testDataSource.InsertParameters.Add("@id1", TextBox1.Text) Option 2: through sqldatasource on page and control parameters<asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:ConnectionStringName %>"InsertCommand="INSERT INTO test(id) VALUES (@id1)" <InsertParameters><asp:ControlParameter ControlID="TextBox1" Name="id1" Type="Int32" /></InsertParameters></asp:SqlDataSource> Feedback would be great, thanks!
I am trying to use the following SQL query to return a set of values:SELECT id, submit_date, company_name, request_type, status FROM tblRequestForms WHERE request_type IN (@RequestType) AND status IN (@Status) ORDER BY id ASCI have tried passing an array of string values to both @RequestType and @Status, but It does not work. Is there any way to pass multiple values like this using parameters?
I want to export an SQL Server table to an Excel Spreadsheet driven by a web interface. I am using Cold Fusion to call a SQL Server Stored procedure. The SP accepts a variable (IDlist) from the web page and sets this to a Global Variable.
The SP then executes a DTS package to export to Excel. The DTS package uses the Global variable in the SQL Query thus:
SELECT ... FROM ... WHERE tblPropertyRegister.IDProperty IN (?);
This works fine when I pass one single ID (@outIDlist = "20") into the stored procedure. But it returns no records when I pass multiple IDs (@outIDlist = "19, 20, 21") into the stored procedure. It works fine also if I "hard code" the IDlist into the DTS query (eg WHERE tblPropertyRegister.IDProperty IN (19, 20, 21);). The problem appears to be in the setting of the global variable in the stored procedure.
Has anyone had any experience with this? Any feed back would be greatly appreciated. TIA
I am developing a website for multiple clients, each with their own separate database on SQL Server 2005. The database structures are identical for all clients. I like to use SQL stored procedures for the security advantages (i.e., don't need to grant access to the tables, only exec permissions on the stored procedures), but maintaining and deploying many sp's across all databases is becoming unwieldy and error-prone.
Is there a way to use parameterized queries (SqlCommand, SqlParameter) in C# code (which could be reused for all databases by changing the connection string) without having to grant access to the tables?
I am having an issue with a Parameterized Query in Sql Ce 3.5 The Query resembles select * from sometable where ((ID = @someId) or (NAME like @someName))
The first part of the query runs fine, the second returns no results when it should.
What I was hoping is that there is some way to run a server trace against the SqlCe file to see the actual query that is ran with the params replaced.

I have a class that works fine using the SQLDataReader but when I try and duplicate the process using a Dataset instead of a SQLDataReader it returnsa a null value. This is the code for the Method to return a datareader
public SqlDataReader GetOrgID() { Singleton s1 = Singleton.Instance(); Guid uuid; uuid = new Guid(s1.User_id); SqlConnection con = new SqlConnection(conString); string selectString = "Select OrgID From aspnet_OrgNames Where UserID = @UserID"; SqlCommand cmd = new SqlCommand(selectString, con); cmd.Parameters.Add("@UserID", SqlDbType.UniqueIdentifier, 16).Value = uuid;
SqlDataAdapter adapter = new SqlDataAdapter(); adapter.SelectCommand = cmd;
adapter.Fill(dataset); return dataset;
}
Assume that the conString is set to a valid connection string. The Singlton passes the userid in from some code in the code behind page ...this functionality works as well. So assume that the Guid is a valid entry..I should return a valid dataset but its null.
I'm trying to do a basic update query which is working on other pages but not on this page. Dim uid As Integer = CInt(Session("uid")) Dim cmd As New SqlCommand("UPDATE [cvdata] SET [jobCompanyName] = @inputJobCompanyName WHERE [user_id] = @uid", strConn) With cmd.Parameters cmd.Parameters.AddWithValue("@inputJobCompanyName", inputJobCompanyName.Text) cmd.Parameters.AddWithValue("@uid", uid) End With cmd.Connection.Open() cmd.ExecuteNonQuery() cmd.Connection.Close() The funny thing is that if i remove inputJobCompanyName.Text and add a custom value (for example "test") it works.So it doesn't seem to read my updated textfield or something im clueless.Kind regards, Mark
If txtLink1 happens to be empty, I want @link1 to enter null. The column in the Sql Server allows for nulls, but I get an error message that says no value was supplied. In short, how do I supply a null value using a parameterized query?
#2: For debugging purposes, how can I view what my SQL string looks like (with all the values entered) before it gets submitted to the database? When I view the string, it still contains the placeholder values (@link1) instead of the actual values.
I have a parameterized query. The parameters contain data from my tables. Some of the parameters could include single quotes. The single quotes are wreaking havoc in my parameterized query. How can I replace single quotes with double quotes inside of my SQL stored procedure?
I know that it's something similar to REPLACE(@variablename, '''''', ''''''''), but I can't get the number of quotes right.
All of the examples that I am seeing are converting the quotes inside of an application. This is not an option for me, as I am calling this stored procedure from a SQL job that will run daily.
I have a smart device project in Visual Studio 2005 that has a SQL Mobile data source. I am trying to create a parameterized query that utilizes 'LIKE' and wildcards. My query is below:
SELECT LocationID, StreetNum, StreetName, rowguid FROM tblLocations WHERE (StreetNum = @StreetNum) AND (StreetName LIKE '%' + @StreetName + '%')
However, when I test this on my PDA, I get the following error:
SQL Execution Error.
Executed SQL statement: SELECT LocationID, StreetNum, StreetName, rowguid FROM tblLocations WHERE (StreetNum = @StreetNum) AND (StreetName LIKE '%' + @StreetName + '%') Error Source: SQL Server Mobile Edition ADO.NET Data Provider Error Message: @StreetName : deerbrook - FormatException
Does anyone know how to add wildcards to a parameter?
I have events which require certain things be done several days before the event and things be done several days after the event. I attempted to use the DATEADD function to subtract 3 days from the event date. The SQL Statement I created did just that, but, it displays 3 days back from today's date.
There are 2 tables:
CalendarCategories -- Table
CalCategoryID -- int field CalCategoryName -- varchar field
CalendarEvents -- Table
CalCategoryID -- int Field Title -- varchar Field StartDate -- DateTime Field
I have to perform some tasks 3 days before the event. So, TODAY, I want to see a listing of those events which are scheduled for 3 days FROM NOW.
This is my current SQL Statement: SELECT DATEADD(d,-3,StartDate) AS [Update Payoffs & Ins], Title AS [Closing Description] FROM CalendarEvents WHERE datepart(dd,StartDate)=datepart(dd,getdate()) AND datepart(mm,StartDate)=datepart(mm,getdate())
This SQL Statement takes TODAY'S events and gives them a date of February 20. See example of the results at http://www.joelwilliamslaw.com/DesktopDefault.aspx?tabid=141
This is what I have already done relative to my calendar listings:
Specific Event Types for the Current Month :
SELECT StartDate AS [Date and Time], CalCategoryName AS [Cls Type], Title AS [Closing Description] FROM CalendarEvents inner join CalendarCategories on CalendarEvents.CalCategoryID = CalendarCategories.CalCategoryID where (CalendarEvents.CalCategoryID = 1 OR CalendarEvents.CalCategoryID = 2 OR CalendarEvents.CalCategoryID = 3 OR CalendarEvents.CalCategoryID = 4 OR CalendarEvents.CalCategoryID = 20) AND (datepart(mm,StartDate)=datepart(mm,getdate()) AND datepart(yy,StartDate)=datepart(yy,getdate())) AND CalendarEvents.ModuleID = 360 ORDER BY StartDate ASC
Specific Event Types for the Current Day:
SELECT StartDate AS [Date and Time], CalCategoryName AS [Cls Type], Title AS [Closing Description] FROM CalendarEvents inner join CalendarCategories on CalendarEvents.CalCategoryID = CalendarCategories.CalCategoryID where (CalendarEvents.CalCategoryID = 1 OR CalendarEvents.CalCategoryID = 2 OR CalendarEvents.CalCategoryID = 3 OR CalendarEvents.CalCategoryID = 4 OR CalendarEvents.CalCategoryID = 20) AND (datepart(dd,StartDate)=datepart(dd,getdate()) AND datepart(mm,StartDate)=datepart(mm,getdate()) AND datepart(yy,StartDate)=datepart(yy,getdate())) AND CalendarEvents.ModuleID = 360 ORDER BY StartDate ASC
I am hoping someone could help me understand why this is happening and perhaps a solution. I am using ASP.NET 2.0 with a SQL 2005 database. In code behind, I am performing a query using a parameter as below: sql = "SELECT field_name FROM myTable WHERE (field_name = @P1)" objCommand.Parameters.Add(New SqlParameter("@P1", TextBox1.Text)) The parameter is obtained from TextBox1 which has valid input. However, the value is not in the table. The query should not return ANY results. However, I am getting one single row back with null values for each field requested in the query. The SQL user account for this query has select, insert, and update permissions on the table. The query is simple, no joins, and the table has no null values in any fields. If I perform the exact same query using an account with select only permission on the table, I get what I was expecting, no records. Then if I go back to the previous user account with more permissioins, and I change the query to pass the paramter this way: sql = String.Format("SELECT field_name FROM myTable WHERE (field_name = {0})", TextBox1.Text) I also get NO records retuned using the same criteria. What is going on here? I would prefer to use the parameterized query method with the account having elevated permissions. Is there some command object setting that can prevent the null row from returning? Thanks!
Hi, Im struggling with this insert statement, I want to use with a AJAX validation Post Form page. Its quite straght forward, if a search query returns null the insert these values. The search query does work, what I mean by that is that txt field values seem to pass for search but not insert. Any help out there cheers Paul if (RowCount == 0) {String strSQL = "INSERT INTO Mail_List (FirstName, Email) VALUES( @FirstName, @Email )";
try {mySqlConn = new SqlConnection(strSqlConn); mySqlConn.Open();SqlCommand cmd = new SqlCommand(); cmd = new SqlCommand(strSQL, mySqlConn);cmd.Parameters.AddWithValue("@FirstName", Request.Form["FirstName"]);cmd.Parameters.AddWithValue("@Email", Request.Form["Email"]); cmd.ExecuteNonQuery(); lblStatus.Text = "Registration Successful"; }
From MS Dynamics NAV 2013 I get a lot of querries that have a where clause like this:
where [Field1] like @p1 and [Field1] < @p2. Field1 is the only primary key field and clustered index. The query also has a TOP 50 clause. @p1 is always a "Starts-With"-value (something like N'abc%').
The query plan uses a clustered index seek but the number of reads look more like a clustered index scan.
Depending on the table size I see 1M or more reads for these querries.
If I rebuild the query in SSMS, but replace the paramerters with actual values I only see a few reads.
I was able to reproduce the issue with a temp table. See code below.
Is there a way to make SQL Server use another strategy when using the parameterized query?
SQL Server Version is 11.0.3401. if object_id('tempdb..#tbl') is not null drop table #tbl; create table #tbl ( [No] nvarchar(20) ,[Description1] nvarchar(250)
joy mundy alluded in her webcast that it is possible to dynamically specify a table name in a parameterized ole db source query. is this true? if so, how can it be done?
know if there is any way out to run execution plan for parameterized queries?
As application is sending queries which are mostly parameterized in nature and values being used are very robust in nature, So i can not even make a guess.
I am using a lookup component in a SSIS data flow. The lookup is a select to a foxpro table. THe lookup works fine with full cache selected. I cannot get the lookup to work with a partial or no cache. I have the latest Foxpro OLE DB driver installed which I understand to support paramaterized queries. Has anyone had success with using cached lookup to Foxpro? Does anyone know how to set the lookup properties of sqlcommand and sqlcommandparam? I am unable to find any examples in BOL or on the web.
Here are some details. IF I go with "use a table or a view" option with the default cache query I get initialization errors
[lkp_lab_worst_value [6170]] Error: An OLE DB error has occurred. Error code: 0x80040E14. An OLE DB record is available. Source: "Microsoft OLE DB Provider for Visual FoxPro" Hresult: 0x80040E14 Description: "Command contains unrecognized phrase/keyword.".
In the advanced editor I see
SQLCommand set to
"select * from `kcf`"
and SQLCommandParam set to
"select * from (select * from `kcf`) as refTable where [refTable].[patkey] = ? and [refTable].[dayof_stay] = ? and [refTable].[modifier] = ? and [refTable].[kcf_code] = ? and [refTable].[source] = ? and [refTable].[kcf_time] = ?"
I believe the above error is because Foxpro V7 does not support the inner subselect . In addition the query contains CRLF without a continuation character (";").
If I remove the CRLF in the sqlcommandparam query, using the advanced editor, I get this design time error "OLE D error occurred while loading column metadata. Check the sqlcommand and sqlcommandparam properties". The designer requires both properties to be set, its unclear to me how the interact.
I cannot find any examples in BOL or on the web on how to set these 2 properties. Can someone give me a few guidelines?
I can get past the design errors by changing sqlcommandparam to a plain select that is VFP 7 compatible ( I removed the subselect and the square brackets):
select * from kcf as refTable where refTable.patkey = ? and refTable.dayof_stay = ? and refTable.modifier = ? and refTable.kcf_code = ? and refTable.source = ? and refTable.kcf_time = ?
But then I get a runtime error

Using c# in the compact framework, is there a way to do a parameterized query for counting the number of records where a specified column is null. I tried all of these, but none of them work:
cmd.Add(new SqlCeParameter("@IntColumn", SqlInt32.Null)); cmd.CommandText = "select count(*) from TableName where IntColumn is not @IntColumn";
cmd.CommandText = "select count(*) from TableName where not IntColumn = @IntColumn";

HelloWhen I use a PreparedStatement (in jdbc) with the following query:SELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = ?ORDER BY group_nameIt takes a significantly longer time to run (the time it takes forexecuteQuery() to return ) than if I useSELECT store_groups_idFROM store_groupsWHERE store_groups_id IS NOT NULLAND type = 'M'ORDER BY group_nameAfter tracing the problem down, it appears that this is not preciselya java issue, but rather has to do with the underlying cost of runningparameterized queries.When I open up MS Enterprise Manager and type the same query in - italso takes far longer for the parameterized query to run when I usethe version of the query with bind (?) parameters.This only happens when the table in question is large - I am seeingthis behaviour for a table with > 1,000,000 records. It doesn't makesense to me why a parameterized query would run SLOWER than acompletely ad-hoc query when it is supposed to be more efficient.Furthermore, if one were to say that the reason for this behaviour isthat the query is first getting compliled and then the parameters aregetting sent over - thus resulting in a longer percieved executiontime - I would respond that if this were the case then A) it shouldn'tbe any different if it were run against a large or small table B) thisperformance hit should only be experienced the first time that thequery is run C) the performance hit should only be 2x the time for thenon-parameterized query takes to run - the difference in response timeis more like 4-10 times the time it takes for the non parameterizedversion to run!!!Is this a sql-server specific problem or something that would pertainto other databases as well? I there something about the coorect use ofbind parameters that I overall don't understand?If I can provide some hints in Java then this would be great..otherwise, do I need to turn/off certain settings on the databaseitself?If nothing else works, I will have to either find or write a wrapperaround the Statement object that acts like a prepared statement but inreality sends regular Statement objects to the JDBC driver. I wouldthen put some inteligence in the database layer for deciding whetherto use this special -hack- object or a regular prepared statementdepending on the expected overhead. (Obviously this logic would onlybe written in once place.. etc.. IoC.. ) HOWEVER, I would desperatelywant to avoid doing this.Please help :)
