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();
=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.
have a table with students details in it, i want to select all the students who joined a class on a particular day and then i need another query to select all students who joined classes over the course of date range eg 03/12/2003 to 12/12/2003.
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
Hi This is really bugging me. All I want to do is add a date in an update statement but when I do it, its adding the wrong date e.g. here is my update statement trying to update a date field update tbl_x set [date]=01/02/2006 where id = 1 when i do this the data comes back as 1900-01-01 00:00:00.000, am I doing something wrong, what is the correct way of doing this. Thanks.
Hi i am trying to write a statement to get the players in a squad based on the StartDate, EndDate of any season and the DateEntered, DateLeft a squad the possible situations are Player joins squad after StartDate and is still there (DateLeft Null) Player joins squad after StartDate and leaves before EndDate Player joins before StartDate and is still there (DateLeft Null) Player joins before StartDate and leaves before EndDate
this is my statement at the moment but i am gettin players that are in the squad this season and last season sp if anyone has any ideas i would really appreciate them select spm.SquadId,Person.Id as ID, IsNull(firstName+ ' ','') + IsNull(MiddleName+ ' ','') + IsNull(LastName,'') as Name, spm.DateEntered, spm.DateLeft From Person LEFT JOIN SquadPlayerMapping spm on spm.PlayerId = Person.Id Where spm.SquadId = 2927 And ((spm.DateLeft IS NULL) Or (spm.DateEntered >= (Select StartDate From Seasons Where ID = 50))) And spm.DateEntered <= (Select EndDate From Seasons Where ID = 50) Order by LastName
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?
SELECT SUM(((CASE WHEN o.date>= a.activity_date, other filter condition, other filter condition THEN (select coalesce(d.balance,d2.balance) from drawtable d where coalesce(d.date, d2.date) < a.activity_date order by d.date desc limit 1) - ( select coalesce(d.balance, d2.balance) from drawtable d where coalesce(d.date, d2.date) = interval 'current date' else end ))
from emailtable a LEFT JOIN opportunity o left join drawtable d left join drawtable d2 etc
The tricky part is I'm joining that same table twice.....would this be better in a max/min case when statement?
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"
I used codes below: sqlA = "select * from order where orderby = 'Mike'" myDataset = makeDataset(sqlA) // I created a function to return a dataset I knew the code below is working: select * from Product where OrderID in ( "select * from order where orderby = 'Mike'") Can I do the way below? select * from Product where OrderID in myDataset
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.
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)
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")
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.
hiI need to write a stored procedure that takes input parameters,andaccording to these parameters the retrieved fields in a selectstatement are chosen.what i need to know is how to make the fields of the select statementconditional,taking in consideration that it is more than one fieldaddedfor exampleSQLStmt="select"if param1 thenSQLStmt=SQLStmt+ field1end ifif param2 thenSQLStmt=SQLStmt+ field2end if
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.
Hello friends, I want to use select statement in a CASE inside procedure. can I do it? of yes then how can i do it ?
following part of the procedure clears my requirement.
SELECT E.EmployeeID, CASE E.EmployeeType WHEN 1 THEN select * from Tbl1 WHEN 2 THEN select * from Tbl2 WHEN 3 THEN select * from Tbl3 END FROM EMPLOYEE E
can any one help me in this? please give me a sample query.
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?
