Current development setup: Visual Studio 2005 (C# language), SQL Server 2005 Express Edition.
I am at this point changing some of my application. It stores a lot of information for times of trains. I decode a file which is text based and my times are stored in varchar(4) columns with the format "HHmm".
I am now at a stage where I need to add values to these times and perform a search based on two time values (a minimum time and maximum time).
I really need to be able to add another varchar(4) value to the times stored in my database (also varchar(4) - may look at this again in future). I have absolutely no interest in storing seconds, modifying the database to include the time colon, nor am I interested in the date portion of a time string, only the 4 digits representing the hours and minutes.
Can this be done easily in SQL server? For example:
varchar(4) of 0445 + varchar(4) of 0027 should result in the time 0512.
Similarly a varchar(4) of 2358 + varchar(4) of 0015 should result in the time 0013.
My current Query takes the DATE value stored in P.CreatedDate and makes it VARCHAR, then stores it in the table. I need to format this to return YYYYMMDD. How would I go about this?
Current Code:
Code: CAST(P.CreatedDate AS VARCHAR) AS DateEntered,
I know that if I have an nvarchar column I can use an equality like = N'supersqlstring' so it doesn't implicit cast as a varchar, like if I were to do ='supersqlstring'. And then I'll be a big SQL hero and all my stored procedures will run before a millisecond can whisper.
But if I'm comparing an nvarchar column to a varchar column, is it better to cast the varchar 'up' to an nvarchar or cast the nvarchar 'down' to a varchar?
For instance:
cast(a.varchar as nvarchar(100)) = an.nvarchar
or
cast(an.nvarchar as varchar(100)) = a.varchar
Leaving aside non-matching, like (at least I don't think) that SQL considers the varchar n to be equal to the nvarchar ń, what's the best way to handle this?
Pretend for a moment that each column contains a mixed letter and number ID with no accented or wiggly-squiggly Unicode characters; it's just designs clashing.
Is there a performance hitch doing it one way or another? Should I use COLLATE? Should one of the columns be altered?
if I 'print' a MONEY value, or cast a MONEY variable to VARCHAR, it automatically rounds it to two decimal places. Maybe that's a built-in convenience, but I'd like to make it not do that.My workaround right now is to first cast my MONEY variabled to DECIMAL(30,4), and then cast the result to VARCHAR, but I'd like to avoid that step if possible.Consider the following
query:DECLARE @UnitCost MONEY SET @UnitCost = .0167 SELECT @UnitCost, CAST(@UnitCost AS VARCHAR(30)), CAST(CAST(@UnitCost AS DECIMAL(30, 4)) AS VARCHAR(30)) - - Results in: 0.0167, 0.02, 0.0167
I have a Derived Column, called Column1, which has a value "PS" in the Expression field of the editor. SSIS detects it as a Unicode string[DT WSTR] in the Data Type property. In the source table, the column is a char datatype with the lenght of 4. How should I cast this in the expression field, so its converted to char(4). I would need the syntax for it, so I can use it in my Expression area. By the way, i am setting a constant value for this derived column, so in your example, pls use the value instead of column name. I would like to see, how it would be coded?? And also, is there a reference for the expression language somewhere for newbies??? thanks a bunch.
I am trying to pull the records which are being affected i.e, comparing the values and if not same then populating the record.
I am using the below condition in where clause however i am getting runt time error as "Conversion failure when converting date and/or time from character string"
Condition in Where clause:
cast(isNull(tab1.Col1,'') as datetime) <> cast(isNull(tab2.col1,'') as datetime)
I would like to cast (convert) data type decimal(24,4) to decimal(21,4). I could not do this using standard casting function CAST(@variable as decimal(21,4)) or CONVERT(decimal(21,4),@variable) because of the following error: "Arithmetic overflow error converting numeric to data type numeric." Is that because of possible loss of the value?
Does anybody know how could I calculate the new date(adding @c to @bor subtracting @b to @c), having for example a declaration like this:DECLARE @a CHAR(12)DECLARE @b DATETIMEDECLARE @c INTSET @b='3.04.04';SET @c=6and to calculate the number of days between two dates with this kindof declaration(@a-@b or @b - @a):DECLARE @a CHAR(12)DECLARE @b DATETIMEDECLARE @c INTSET @a='12.2.04';SET @b='3.04.04';Thanks in advance.
Implement time interval type in the form of a user defined type in SS2k8r2? Specifically an interval type described in the book Temporal Data and the Relational Model by C. J. Date at all. As an example, an interval is below:
1/4/2006:1/10/2006
which would mean the time period from 1/4 to 1/10.
Hi guys I need immediate help with a query that I am trying to write. I want to sum the values in a query but the field has a type of varchar and it has decimal numbers too. So if I do the query something like that, that converts the field to int, I get the error message. I tried converting it into real or float but I get error message on that too. I need help with adding the calculatedValues and getting there sum. I would appreciate any help with that.
Thanks -Sarah Select SUM(Convert(int, calculatedValue)) from monitor.dbo.monHistory where LocalTimeWithoutDst > '8/26/06' and LocalTimeWithoutDst < '8/28/06'
This is the error message I recieve: Conversion failed when converting the varchar value '274.2' to data type int.
I encounter this particular error. Exception Details: System.Data.SqlClient.SqlException: The data types varchar and text are incompatible in the equal to operator. Line 21: Dim reader As SqlDataReader = command.ExecuteReader() This is the first time I'm trying out with MS SQL so I'm abit lost. I hope my code is correct and I've did a little search. I did not set "Text" in my database, I use int and varchar. Here's the affected part of my code and the database. Dim password As String = "" Dim querystring As String = "SELECT Password FROM Member WHERE Username = @username"

I have a varchar field which holds IDs like (1, 3, 5, 19, 23) when I order it, i get it ordered in ASCII order like (1, 19, 23, 3, 5) rather than (1, 3, 5, 19, 23) Even if I convert it to int, I won't be able to order it.
is there any way I can order a varchar field numerically?
I write using the SQL ODBC driver from software into a SLQ table called UPSSHIPMENT the format is as followed: JobNumber varchar 50 Weight real 4 FreightCost varchar 8 TrackingNumber varchar 50 Shipmethod varchar 50 VOIDID varchar 3
I then have a trigger set to update the PACKAGE table as followed CREATE TRIGGER [UPS] ON dbo.UPSSHIPMENT FOR INSERT
AS
BEGIN UPDATE PACKAGE SET WEIGHT = inserted.WEIGHT, FREIGHTCOST = inserted.FREIGHTCOST, TRACKINGNUMBER = inserted.TRACKINGNUMBER, COMMENTS = inserted.SHIPMETHOD FROM PACKAGE INNER JOIN inserted on PACKAGE.JOBNUMBER = inserted.JOBNUMBER WHERE inserted.VOIDID = 'N'
UPDATE PACKAGE SET WEIGHT = '', FREIGHTCOST = '0.00', TRACKINGNUMBER = '', COMMENTS = 'UPS VOID' FROM PACKAGE INNER JOIN inserted on PACKAGE.JOBNUMBER = inserted.JOBNUMBER WHERE inserted.VOIDID = 'Y'
END
The format of the PACKAGE table is as followed Jobnumber varchar 50 FreightCost money 8 TrackingNumber varchar 50 Comments varchar 2000 Weight real 4
I am getting the following error --------------------------- Microsoft SQL-DMO (ODBC SQLState: 42000) --------------------------- Error 260: Disallowed implicit conversion from data type varchar to data type money, table 'TESTing.dbo.Package', column 'FreightCost'.

How do you use the convert function to change the data before the update? Thank You! :mad:
I am parsing a documnet and i am grabbing that document into a variable of datatype varchar. The document contains more than 8k(upto 30k characters) characters. So how can I handle this situation.How can I get that document into my local varchar variable.

How do you set the type to varChar like this using markup (xml tags in the .aspx page)? If I were creating a SQLDataSource control declaratively and one of the parameters needed to be set to VarChar rather than just a string I would set a parameter type to varchar using this syntax: myAdapter.UpdateCommand.Paramters.Add("@Title", SqlDbType.VarChar, 80, "Title"); SQLDataSource control as a default will create parameters as strings even though the table it is pointing to has type varchar in it such as below: <asp:Parameter Name="Title" Type="String" /> If I leave it like that, I get the following error below (as expected) since it really needs to be type SqlDbType.VarChar "The data types text and nvarchar are incompatible in the equal to operator" Below is example default markup the SqlDataSource control creates with an update. Where in this markup should I change things so it will update correctly to varchar rather than just trying to throw a string in the table? <asp:SqlDataSource ID="IISLearning_Content_SqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:IISLearningConnectionString %>" SelectCommand=""></asp:SqlDataSource> <asp:SqlDataSource ID="MySqlDataSource" runat="server" ConflictDetection="CompareAllValues" ConnectionString="<%$ ConnectionStrings:MyConnectionString %>" OldValuesParameterFormatString="original_{0}" SelectCommand="SELECT * FROM [MyTable]" UpdateCommand="UPDATE [MyTable] SET [Title] = @Title WHERE [ID] = @original_ID AND [Title] = @original_Title"> <UpdateParameters> <asp:Parameter Name="Title" Type="String" /> <asp:Parameter Name="original_ID" Type="Int32" /> <asp:Parameter Name="original_Title" Type="String" /> </UpdateParameters> </asp:SqlDataSource>
I have a table with a column (locationID) of int data type, I want to pass a list of locationID's to a stored procedure using the IN operator (e.g. WHERE LocationID IN (list of locationID's)). What can I do to achieve this????
My stored procedure looks like this:
CREATE PROCEDURE [sp_test] @sLocIDs varchar(30) AS select count(distinct TimeZoneID) As timezones, from dimLocation WHERE LocationID IN (@sLocIDs)
When I test it: exec sp_test @sLocIDs = '1,2,10' I get "Error converting data type varchar to int"
In my table I am using varchar to save a date like this 2-dec-2011. Now I have a requirement where i need to select employee who where present in a month so for that I need a query so that i can pull out all the employees who are present in dec like :
Code: select * from emp_attendence where date = 'dec-2011'
I have a DB named zCIFRecord with a column named CIFUpdateDate which is of datatype varchar. The data is a date MM/DD/YYYY 01/30/2008, this is al that is in this column. I can search this colum for individual dates and for a range of dates. My problem is with a range of dates that is not within the same year, such as;
SELECT [CIFPan]
,[CIFMemNum]
,[CIFLName]
,[CIFFName]
FROM [FutureSoft].[dbo].[zCIFRecord]
WHERE [CIFUpdateDate] between '12/01/2007' and '01/30/2008'
will return nothing because it seems to only search on the 12 then the 01 then the 2008. this search can be performed properly on dates within the same year such as;
SELECT [CIFPan]
,[CIFMemNum]
,[CIFLName]
,[CIFFName]
FROM [FutureSoft].[dbo].[zCIFRecord]
WHERE [CIFUpdateDate] between '01/01/2008' and '01/30/2008'
will return the proper values because now all the numbers are in correct order. How can i create a search that lets me perform the first query as well as the second query. I tried to convert to a float but you cant convert a varchar to a float.
I inserted a record in table on DB created on SQLServer 2005 and found out that the one of the column values is shown as '??????' instead of showing the encrypted value that I sent with the insert statement.3

Hi, It is not exactly what I stated in the subject - It's an outcome - exception thrown while executing non-query command. I get this exception when I try to execute my stored procedure that takes datetime as one of its parameters. I am using dataset designer to create table adapters and build queries. Then I simply use objectdatasource component that uses one of the table adapters and bind it to for example a detailsview control. When I run this in debug mode and trace the objects everything looks perfect including these datetime parameters. It is sql server that throws the exception. I ran the sql profiler to see what exactly is going on, and I captured the command that is sent by ADO - it's broken into several lines right in the middle of my datetime parameters... this is the source of the problem. Everything is working fine when I take this command and execute it as a single line in the sql management studio. Is there anything about ADO that I do not know?
I have the following query which has been giving me headaches for days : SELECT SCCode [Service Catalog Code], FileName [File Name], FullName [Full Name], FileExtension [Extension], FileSize [Size], Author [Author], CONVERT(VARCHAR(50),CAST(LastModified AS SMALLDATETIME), 120) [Last Modified], CONVERT(VARCHAR(50),CAST(LastAccessed AS SMALLDATETIME), 120) [Last Accessed], TimesAccessed [Downloads], UploadedBy [Uploaded By], CONVERT(VARCHAR(50),CAST(UploadedAt AS SMALLDATETIME), 120) [Uploaded At] FROM #TempTable WHERE id > @firstitem AND id < @lastitem ORDER BY CASE WHEN @sortcolumn = 'Service Catalog Code' THEN SCCode WHEN @sortcolumn = 'File Name' THEN FileName WHEN @sortcolumn = 'Extension' THEN FileExtension WHEN @sortcolumn = 'Size' THEN FileSize WHEN @sortcolumn = 'Author' THEN Author WHEN @sortcolumn = 'Last Modified' THEN CONVERT(VARCHAR(50),CAST(LastModified AS SMALLDATETIME), 120) WHEN @sortcolumn = 'Last Accessed' THEN CONVERT(VARCHAR(50),CAST(LastAccessed AS SMALLDATETIME), 120) WHEN @sortcolumn = 'Downloads' THEN TimesAccessed WHEN @sortcolumn = 'Uploaded By' THEN UploadedBy WHEN @sortcolumn = 'Uploaded At' THEN CONVERT(VARCHAR(50),CAST(UploadedAt AS SMALLDATETIME), 120) END ASCWhen my @sortcolumn parameter is either FileSize (BIGINT) or TimesAccessed (BIGINT) then the query returns the data without any problem. However, if I use a different @sortcolumn value such as "Author" then I keep getting "Error converting data type varchar to bigint."A solution that seems to work is to drop CASE and use lots of IF statements instead. I don't prefer to do this because it requires me to repeat the same select statement for each and every possible @sortcolumn value!Does anyone know how to solve this? Help!
