DataSource Controls :: Filtering Date Stored As Varchar In Table
Mar 9, 2010
I save dates as a string in a varchar data field named "TilDato" in a SQLServer-express table. I want to filter the records smaller than a specific date from a variable in the script. I try the following statement, but it does not seems function logically.
objCmd = new
SqlCommand("SELECT * FROM Reservering WHERE @laanedato<=TilDato",myConn2);
objCmd.Parameters.Add("@laanedato", laanedato);
objRdr = objCmd.ExecuteReader();
I am storing date data in sql server as varchar but I want to make comaparisons on this field in where clause- like this field from 2 days before or after etc
I'm working on an application that allows our Office Services people to schedule employee location moves. The page I'm currently working on allows for modification of scheduled moves. When the user attempts to save changes in this page, the app runs a stored proc to see if there are any conflicts, e.g., someone already sitting in the new location, someone scheduled to move into the employee's location before the employee is scheduled to move, etc. These conflicts, if any, are then displayed for the user and he/she has to make changes to one or more moves to resolve the conflict. This all works just fine. My problem comes when the user has resolved all the conflicts (or thinks he or she has). I need to check again to make sure that there are not still conflicts somewhere before allowing the data to be saved back to the database. So, I've got data for at least two scheduled moves, but this data does not necessarily match what's in the database.
I want to run the same stored procedure that I initially used on this dataset. The stored proc uses three database tables, plus the proposed move information to check for conflicts. What I'm trying to do (but please tell me if there's a totally different approach that would be better) is I've created 3 DataTables, using the 3 tables that my stored proc uses. The tables are Employee, Location and Moves. I've then put all these tables into a DataSet. I've updated my Moves DataTable with the proposed new move information. Now I want to run my stored proc on this dataset to see if I get any rows (i.e., if there are still any conflicts). But I can't just run the stored proc; it references the tables in the database. I want to run my stored proc on this DataSet. The stored proc is very long and takes 5 parameters which are referenced all through it, so I don't want to just create a DataViewManager using the SQL.
I am trying to filter a column for when the text matches "True" in the column. I am using the following syntax, don't get an error, but it isn't working.
Select ContactID,FirstName,LastName,Officer,Title from Contacts Where officer = "True"
Using a dropdownlist, I can filter (by changing datasource) the results based on customer names in a dropdownlist. This datasource, working perfectly, looks like this:
[Code]....
Now, using a textbox and a ajax calendar, I would like to be able to filter on the date as well, but my datasource so far:
[Code]....
doesn't work very good. In some case sit doesnt show anything, in onther situations - with 10 records for a given date, it only shows one.
Question one: How do I make the last datasource work? Its probably - again-again - something with the datetime formats, but for the life of me, I can't see how to do.
Question two: The Ideal solution would be using the first datasource, SqlDataSourceAllLoads, and then be able to filter the results with filterexpressions/parameters, but again, how? The filterparameters would origin from a DropDownListKunder, matching the tblDeliveredInfo.deliveryInfo_FirmaNavn as seen in the second datasource, while the date comes from the textbox txtStartDate (databinding fired by a button).
I have a standard gridview, with the standard paging and sorting interface enabled.The application holds appointments for three organisational units, with a maximum of 3000 appointment records being returned across all three units. The appointment records are quite small.
The choice I am faced with is to:
1. Have an Org Unit dropdown which returns to the datasource on change of selection and at inital databind, and returns appointment records for one org unit at a time i.e. approx 1000 records.
2. Have the objectdatasource return all 3000 appointment records for all org units at initial databind, and filter the objectdatasource by org unit on change of selection, thereby saving a trip to the datasource.
I guess the question boils down to identifying the point at which querying the datasource by org unit is more efficient than filtering the records returned by org unit.
Is 3000 records a lot for a gridview to be paging and sorting etc.
I've written a stored procedure which uses a table variable. The stored procedure is shown below:
[Code]....
The table variable @CaseNumbers is declared, and is a bunch of values are inserted using a table-valued function called SplitStringIntoInts. At this point I can select from @CaseNumbers and this works fine.But when I try to join onto @CaseNumbers, the name '@CaseNumbers' in the ON clause is highlighted with the error 'Must declare scalar variable @CaseNumbers'. What?! It's not scalar, I declared it ages ago and I have used it since!
my stored procedure is always extract some data into temp table such as"select name,address,content into #TEMP1 from table1,table2,table3" finally, select another table together with #TEMP1 to extract all desire data from one queryselect T.name,T.address,T.content,C.other from #TEMP1 T, otherTable C where T.ID=C.IDI would like to ask if i want to join one more table T2 into final query with "otherTable left C outer join on C.ID=T2.ID"
i m using ##Temp Table in stored procedure..it gives this error There is already an object named '##people' in the database.in two codition1.in case of multisession2. if transaction drop in between even i drop Table in Last in stored procedure..what can i use in place of temp table to hold data for a time being
This may not be the correct place to put this as it is both a stored procedure AND Visual Studio 2008 problem.
I have the following stored procedure:
[Code]....
I have been mokeying around with it because of what is happening. I have a dataset, call it dataset1. I drag this stored procedure onto the dataset. I EXPECT a datatable to appear, instead the data set adds this store procedure to the queries table adapter and sets the exec mode to 'NonQuery' which unless I am very mistaken, means "don't expect a dataset back from this' when in fact you DO expect a dataset back from this.
The SQL server is a Windows 2000 Server running SQL 2000. It has never caused us a moments grief since we set it up oh-so-many years ago.
If I connect to a different database and drag a query into the same dataset I get a datatable as I expect. I cannot see where / how this procedure could be wrong. The query when executed returns exactly the data I expect, in the format I expect (looks like a table, acts like a table in the Query analyzer).
I have a table in SQL where I insert data (CatCodes) using C# code but I want to insert ID code (DealerID) with it as well. Following is my Stored Procedure and C# code:
[Code]....
C#:
[Code]....
As you can see, I am insering CatCode values in Categories table using string cbspecialities.
How can I insert DealerID the same way? DealerID is automatically generated in tblDealers table when "InsertExternalInfo" asp.SqlDataSource control runs "InfoInsert" SP.
I have a Procedure which should return only 1 Record on selecting record according to Priority.
BEGIN DECLARE @Accounts nvarchar(MAX) SELECT @Accounts = ISNULL([map_user_modules].[Accounts], '') FROM [map_user_modules] WHERE [map_user_modules].[id_user] = 231 AND [map_user_modules].[id_module] = 5 IF ((@Accounts = '') OR (@Accounts = 'All')) SELECT @Accounts = null
BEGIN Select @@ROWCOUNT as Priority2 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority3 END IF @@ROWCOUNT = 1 BEGIN Return END
BEGIN Select @@ROWCOUNT as Priority4 END IF @@ROWCOUNT = 1 BEGIN Return END
In the above statement Suppose we take a scenario where Select @@ROWCOUNT as Priority3 is executed, I get two tables returned, One is the Table returned by Select @@ROWCOUNT as Priority3 and the other is the Table returned by Select @@ROWCOUNT as Priority2 which has no Records. How can I eliminate the Empty table that returns no records.
I am trying to get the @@Identity from a table by using a stored procedure called by my asp.net website. I am using a datareader to do this but get an error as it tells me it cannot convert the returned value to getint. Here is my code. What should I be using instead of getint?
Dim myReader = cmd.ExecuteReader() While (myReader.Read()) intID = myReader.GetInt32(0) End While myReader.Close()
More specifically, i'm trying to create a stored procedure that displays data from a table if the date column in the table matches a specific day of the week. (IE. Monday, Tuesday, ect...)
I have a stored procedure which must be provided with a requested FROM date and TO date. If a given FROM date and TO date is in between any record set available in the table, it must return an error. For example, According to above table, there is a request FROM 01/01/2010 TO 10/01/2010, and If the user enters 06/01/2010 as FROM date [Requested FROM date is already in between the Record ID 01 - FROM date and TO Date] , thus, it must display an error, or print a message.
I have two tables dept and employees those table have parent and child relation ship link column is deptno i want to delte department even this departmetn contains employees i want to write storedprocedure for first delte employees and after department if i wrtie these two querys in storedprocedure will i get any problems
Begin Delete from tbl_employees where Department_Id=@Department_Id Delete from tbl_Department where Department_Id=@Department_Id RETURN END
Not a fan of creation and modifcation data in each table's row but I don't make the rules here. Something about normal comes to mind. Simple method to insert or update data in a table ia EF. Datatype = smalldatetime and no it is not changing across schema. Don't care about milli seconds. In oOrg = null I always fail because of a datatype mismatch.Not sure but didn't M$ make both of these products, and shouldn't the EF know about a smalldatetime when it reads the schema? So what is the fix outside of changing many tables to be datetime which is frowned upon at this piont.
public static String updateOrgs(Orgs org, Guid user) { using (ELogs2Entities EL = new ELogs2Entities())
