Problem With Dates In Dataset Select Statement
Mar 14, 2007
I'm using the designer to create/modify strongly typed datasets. I have one select statement that I'm having considerable trouble with. The user selects search parameters from a form. These search parameters are used to filter the data sent to a gridview control. Three of these parameters are almost enough to make me abandon the dataset in this case.
The first two are minimum and maximum age. I have a birth date field, but not an age field - ages have a habit of changing without user intervention <grin> and can be calculated. In ASP I'd do something like this:
strSQL = "SELECT [DATE OF BIRTH], [FIRST NAME], [LAST NAME], [STATE], [MALE OR FEMALE] FROM members WHERE (DateDiff(yyyy, [DATE OF BIRTH], '" & date & "') >= " & strLowerAge & ") AND (DateDiff(yyyy, [DATE OF BIRTH], '" & date & "') <= " & strUpperAge & ")"
I can't figure out how to get datediff working in the designer much less testing against upper and lower age limits.
The third parameter is astrological sign. Again, I calculate it based on the birth date. I don't have a field for it. I could, but I would have to modify all the pages that add or edit records to the database to insure all the records that have birth dates also have the right sign. I'm leaning in that direction, but is it possible to accept a sign as a parameter and calculate, based on the birth date, which records qualify?
I need to get the age issue fixed. The sign is a nice to have, since I can do it another way if I have to.
BTW: I did decide to abandon the dataset in favor of a SqlDataSource control. This allowed me to build my select string in the code behind the way I would have in ASP. This resulted in paging and sorting not working properly. Sorting would be nice, paging is necessary. I'm pretty sure going back to the dataset or using a stored procedure would fix the paging problem, and I've yet to work with stored procedures (it's on my list of things to learn). Any comments or feedback on this would be avidly read and appreciated.

right now I am able to retrieve the month and year from a field by month(TS_Date), Year(TS_Date), my question is can I put both results as one so output can say Date 2 2008 instead of two columns with month 2 year 2008.
any help would be appreciated

Hello,
I have been reading about how you shouldn't build dynamic SQL statements (see TextBox1.Text in line 3) and should use parameters instead, but I haven't yet found how to create a SELECT statement with a parameter that fills a dataset. If anyone can show me the correct way of doing this I would appreciate it so I can add it to my code snippets for proper coding practices. Thanks in advance for any assistance.
string strConnectionString = ConfigurationManager.ConnectionStrings["sqlConnectionString"].ConnectionString;
SqlConnection myConnection = new SqlConnection(strConnectionString);
-> string sqlSelect = "select * from customers where city = " + "'" + TextBox1.Text + "'";
SqlDataAdapter da = new SqlDataAdapter(sqlSelect, myConnection);
DataSet ds = new DataSet();
myConnection.Open();
da.Fill(ds, "myDataset");
myConnection.Close();

Using this IIF statement:
=CountDistinct(IIF(Fields!Released_DT.Value = Fields!Date2.Value, Fields!Name.Value,
Nothing))
Released_DT = a date - 09/03/2015 or 09/02/2015
Date2 = returns another date value in this case 09/03/2015
What I'm trying to do is: count distinct number of people (Fields!Name.Value) if the Relased_DT = Date2.My IIF statement is returning a zero value.

I have a report that uses different datasets based on the year selected by a user.
I have a year_id parameter that sets a report variable named dataset_chosen. I have varified that these are working correctly together.
I have attempted populating table cell data to display from the chosen dataset. As yet to no avail.
How could I display data from the dataset a user selects via the year_id options?

i have tried with the following query, i need help putting my queries together
select * from tblstudents where classID='1' and studentstartdate between ('03/12/2004') and ('03/12/2004')
when i run this query i get this message
Server: Msg 242, Level 16, State 3, Line 1
The conversion of a char data type to a datetime data type resulted in an out-of-range datetime value.
the studentstartdate field is set as datetime 8 and the date looks like this in the table 03/12/2004 03:12:15

I have following SQL statement which I run on an Access database. ( Program written in VB.NET )
'---------
SELECT c.*
FROM Communications AS c
WHERE CommDate Between #1/4/2005# And #5/4/2005#;
'------------
I've put dummy values in the database for dates between 1st and 8th of april... And running this query suprisingly gives back ALL rows in the table... Also the entries for the 6th, 7th and 8th of april... In fact it just gives back the WHOLE table, no matter which values I add...
If I use '1/4/2005' (not with #) then I get an error back.
Anybody an Idea how to make a BETWEEN statement work in an access database?
Thanks,
Frederik

Hi all,
I have a database with a field which contains a load of dates in this format 01/03/1998
What I want to do is select all the records from the database where the month of the date is what ever, this month or the month the customer selected etc.
I suspected it may be something like the following (which doesnt work)
sql = "SELECT * FROM avail_lowermill WHERE CH_Arrival.month = " & showmonth & " ORDER by CH_Arrival"
Can anyone suggest how I can do this?
Thanks in advance

I have the following problem:
in a data flow, if inserting new records, there are columns that take some default values. These default values are kept in a table in case the user wants to change them some day. Def. values could not be assigned at a table level because there's another dataflow that populates the same table, but the rules for the default values are different.
Since I want to extract these values only if there is at least one new row, I'm not fond of the idea to use Execute SQL Task (to save the default values in a variable) before the actual Data Flow. What are my options in getting these values in a Data Flow right before inserting? Thank you for the help.

How would I go about selecting a datetime field for a date range?
e.g.
$start_date = 04/11/2007
$end_date = $05/11/2007
I would have thought it would be something like this:
SELECT * FROM order_details BETWEEN $start_date AND $end_date
BUt I cannot get it to work in MS SQL? Would it be anything to do with the data stored such as 5/11/2007 12:00:00 AM

I have the following table of data. I need to take a date from a large table and do the following case:CASEWhen date < date(0) Then '0'When date between date(0) and date(1) Then '1'When date between date(1) and date(2) Then '2'When date >= date(3) Then '3'What I need is to be able to read all the dates the the Date table, sort then chronologically, and build the dynamic CASE statement so that the first When statement is < Date(0) and the last When statement is >= Date(Last)I hope I am making sense. Dates will be added to the table about once a year or so and I don't want to keep going back into the sql function and rewrite it with the latest date. Any ideas how to manipulate these dates into a case statement? Don't worry about the second table below. I just wanted you to see why I need to return an int from the Case function.thanksMilton

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

I have a sqlDataSource control that has its select command and parameters set dynamically. One of the parameters is a date, which should be in smalldatetime format (ie, 12/22/2006). Obviously, using SQL Server, the data is stored with both date and time. The problem is, I cannot get any data selected. I initially thought that I needed to tell it to only look at the date and not the time, but from what I have seen this should work. Here is the pertinent code.
dim seldate as datetime
selDate = Session("ChosenDate")
Dim SelCmd As String = "SELECT [PatientName], [AssignedTo], [CPT], [CPT2], [HospitalID], [RoomNbr], [ACType], [TxDx1], [TxDx2], [MRNbr], [Notes], [PatientID], [PCPID], [ResidentID], [Status], [CaseID], [AdmitDate], [crtd_datetime] FROM [DailyBilling] WHERE ([crtd_datetime] = @crtd_datetime) and ([AssignedTo] = @AssignedTo) and ([HospitalID] = @HospitalID) ORDER BY [PatientName]"
SqlDataSource1.SelectCommand = SelCmd
SqlDataSource1.SelectParameters.Clear()
Dim parFilterProvider As New ControlParameter()
parFilterProvider.ControlID = "ddlProvider"
parFilterProvider.Name = "AssignedTo"
parFilterProvider.Type = TypeCode.String
SqlDataSource1.SelectParameters.Add(parFilterProvider)
Dim parFilterHospital As New ControlParameter()
parFilterHospital.ControlID = "ddlHospitals"
parFilterHospital.Name = "HospitalID"
parFilterHospital.Type = TypeCode.String
SqlDataSource1.SelectParameters.Add(parFilterHospital)
Dim parFilterStatus As New Parameter()
parFilterStatus.Name = "crtd_datetime"
parFilterStatus.DefaultValue = selDate.ToShortDateString
parFilterStatus.Type = TypeCode.DateTime
SqlDataSource1.SelectParameters.Add(parFilterStatus)
Gridview1.databind()
Any ideas?

Hi everyone,
I've got a problem that I've been unable to work out.
I'm wanting to count the number of people that fall into a specific age group. For simplicity, lets say I'm JUST after people that are 10 years old.
This is what I'm trying to do:
SELECT 'Aged 10 years old', count(*)
FROM [People]
WHERE ([DOB] + [Date Entered]) = ?5 years?
Does anyone have a solution to this?
Thanks

I am trying to select all records added between 2 dates that the user inputs into a form and am having problems. I had this working no problems with asp but can't seem to get it working with .net. BTW I am using SQL Server and Visual Studio.
The asp.net code I am trying to use is:
Me.SqlSelectCommand1.CommandText = "SELECT news_title, news_date, news_type, news_link FROM news WHERE (news_type = 'news') AND (news_date BETWEEN CONVERT(DATETIME, '"" & startdate & ""', 102) AND CONVERT(DATETIME, '"" & enddate & ""', 102))"
....
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim startdate As DateTime
startdate = Request.Form("date_from")
Dim enddate As DateTime
enddate = Request.Form("date_to")
SqlDataAdapter1.Fill(DataSet1)
Repeater1.DataSource = DataSet1
Repeater1.DataBind()
End Sub
With this I am getting the following error:
"Syntax error converting datetime from character string. "
So I am assuming it is something to do with the way I am getting the date from the form as when I hardcode the dates in it works???
Any help would be greatly appreciated, thanx

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.

Ends up with rows:
'2015-01-01'
'2015-01-02'
'2015-01-03'
'2015-01-04'
'2015-01-05'

Hi,
OK, trying to return the results from two SQL statements into a DataSet using SqlDataAdapter. The SELECT statements query the same table but are looking for different records based on the date that the records were inserted - the 1st query looks for records fro the current month and the 2nd one looks at the same records but for the previous month. The goal is to be able to do some math within a repeater and get the difference between the two records.
Sounds easy enough and it has worked for me in different variations of the same idea but not this time - here's the code:
Protected Sub buildPartsReport(ByVal varHC) objConn.Open() sSQL = "SELECT ap.id,item_model,item_sn,aircraft_id,item_loc=item_type+ ' on ' +(SELECT tnum FROM T_Aircraft WHERE id=aircraft_id),apt.tot_time As endTimes,apt.tot_cycles as endCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & rD & "' AND item_type LIKE 'engine%';SELECT ap.id,apt.part_id,apt.tot_time as startTimes,apt.tot_cycles as startCycles FROM T_Aircraft_Parts ap, T_Aircraft_Parts_Totals apt WHERE ap.id=apt.part_id AND report_date= '" & oldRD & "' AND item_type LIKE 'engine%'" Dim objCommand As New SqlDataAdapter(sSQL, objConn) DS = New DataSet() objCommand.Fill(DS) Repeater1.DataSource = DS Repeater1.DataBind() DS.Dispose() objCommand.Dispose() objConn.Close() End Sub
Sorry if it wrapped a bit. The "rD" and "oldRD" are the variables for the date ranges (currently set to static numbers for testing). I'm getting the following error when I run this on an ASP.Net page:
System.Web.HttpException: DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'startTimes'.
The code works fine when run via the Query Tool on the SQL server (SQL 2005 Std) though it produces two distinct "tables" which I'm guessing is the problem. I've tried variations on the code including creating a 2nd dataset and then attempting a merge (no joy) and I've tried the ".TableName" route but it complains about trying to add the tablename twice.
Thoughts? I need to get this to work - it is part of a reporting component for an application that I'm developing and I'm stuck. Thanks as always...

I have a remote report ...
I need to call one of two stored procedures depending on which parameters were passed to the report. (Both stored procedures return the same fields.)
Does SQL Reporting Services allow you to switch the dataset or stored procedure name dynamically? If so, where do I put the logic? Right now I have it working with one stored procedure.
I'm thinking that I should just make one stored procedure that takes all parameters and calls one of the other two stored procedures. Do I have any options besides this?
Thanks in advance!
