Dynamic SQL - Date To Varchar
Jun 18, 2008
I cannot execute a dynamic SQL function when I convert a datetime to a string:
declare @date_key datetime
set @date_key = '5/1/08'
select * from OPENROWSET('SQLOLEDB','Data Source=test;Trusted_Connection=yes; Integrated Security=SSPI'
,'Execute dbFinance..spCalc ''' + convert(varchar(20), @date_key, 101) +'''')
The code below produces the exact same text but DOES work:
select * from OPENROWSET('SQLOLEDB','Data Source=test;Trusted_Connection=yes; Integrated Security=SSPI','Execute dbFinance..spCalc ''05/01/2008''')

I have a column of data in a table that has date formatted as '2006-03-26 00:00:00.000'
What T-SQL command that will alter the column so that it is now Varchar '03-26-2006'?I also want to know how to do the opposite... if I have '03-26-2006' via command, how do I convert the column of the table to be datetime from varchar

For the example stored procedure below, lets say I want to use the "sp_executesql" stored procedure instead of "EXECUTE".
CREATE PROCEDURE [dbo].[spGetEmployees]
@managerId int,
@employeeIdList nvarchar( 200 )
AS
EXECUTE
(
'SELECT *
FROM [dbo].[hrEmployees]
WHERE [ManagerID] = ' + CAST( @managerId AS nvarchar ) + '
AND [EmployeeID] IN (' + @employeeIdList + ')'
)
I want to rewrite it something like this. Please see MSDN documentation ( http://msdn2.microsoft.com/en-us/library/ms188001.aspx ) for sp_executesql stored procedure usage.DECLARE @selectStatement nvarchar(500)
SET @selectStatement = 'SELECT * FROM [dbo].[hrEmployees] WHERE [ManagerID] = @paramManagerID AND [EmployeeID] IN (' + @employeeIdList + ')'
DECLARE @paramList nvarchar(500)
SET @paramList = '@paramManagerID int'
EXECUTE sp_executesql @selectStatement, @paramList, @paramManagerID = @managerId
Reason for using "sp_executesql" is the performance gain.However, as you can see, the @employeeIdList cannot be included as part of the Parameter List ( @paramList )like the @managerId since it **has** to be passed in as a varchar ( example: @employeeIdList = '1,2,3,4' ).
My Question Is there a way to include it as a parameter instead of it being part of the embedded dynamic SQL syntax?

I'm using SSIS to import data from a table (SQL) containing varchar fields. The problem is, that those varchar fields are changing over time (sometimes shrinking and sometimes expanding). I.e. from varchar(16) to varchar(20).
When I create my SSIS package, the package seem to store information about the length of each source-field. At runtime, if the field-length is larger then what the package expects an error is thown.
Is there anyway around this problem?
Oh, yeah... My destination fields are a lot wider then the source fields, so the problem is not that the varchar values doesn't fit in my destination table, but that the package expects the source to be smaller...

Hi All:
I am trying to execute a dynamic sql, the dynamic sql makes use of an inbound paramter defined as varchar.
When I try to execute it fails, because it does not plavce the inbound paramter in quotes.
Any help would be appreciated.
In the bound search as an eaxmple can be" 'NY'
@P_SEARCH_VALUE='NY'
SET @V_SQL_FILTER = N' WHERE STATE = '+@P_SEARCH_VALUE
SET @V_SQL=@V_BASE_SQL+@V_SQL_FILTER
EXEC sp_executesql @V_SQL
Here is the v_sql out put:
SELECT TOP 100 * FROM V$ZIPCODE_LOOKUP_ALL WHERE STATE = NY
As you can see the sql will fail because the NY is not in quotes.
I tried using '@P_SEARCH_VALUE''' and other forms but could not get it work.

This is probably a very simple question, but there it goes.
I have a DB table with the following varchar value:
1/12/2004
I want to convert the specified data to the following:
Monday, January 12th, 2004
I guess i want to:
Convert(DATETIME, '1/12/2004'), But...
I want it to be inserted into the new table as a long date type value.
Is this possible?
Thanks in advance!

Hi
I have a varchar field with values like "Jun 13 1995 12:" I want to change the type of the field to Date and the format of the values to "mm/dd/yyyy".
If I change the type of the field in the design view to Date, SQL gives me an error saying that the type cannot be changed and data would be lost.
So I think changing the dates to the mm/dd/yyyy format first and then changing the field type from varchar to date would work.
Can someone please help me as how to do this.
Thanks

Hi All,
We are trying to create a new view within SQL 2000. We have two colums from seperate tables, 1 is a datetime data type which stores the Date the other is a varchar that stores the time.
What we would like to do is merge the two into one datetime colum so we can work with this one datetime column. Unfortunaly it is not posible to have this entered into the one field at data entry. If needed we can change the time column from a varchar to a datetime datatype.
Also our SQL knowledge is minimal.
Hope this makes sense any help would be deeply appreciated.
Regards
Darren

I have developed a CF application and now need to add some charts to it for admin purposes. I have a form page that uses a calendar widget to let a manager select a date range and submits to display data for that timeframe. I need to convert the formfields to a date for my WHERE clause in my query. My experience to this point has just been simple queries of one table. below is a sample I found and modified numerous time to try and make it work with no success.
Can anyone give me a hand with this?
SELECT COUNT ((CHG_TYP_CD)) AS CHG_TYP,
CHG_TYP_CD
FROM WRK_RQS
WHERE(CAST('form.startdate' AS datetime) >= RQS_SBM_TS)
AND
(CAST('form.startdate' AS datetime) <= RQS_SBM_TS)
GROUP BYCHG_TYP_CD

for some odd reason our other programmer used varchar datatype to store dates. he claims it gives him more control. now i am trying to sort it based on date. so i create a procedure:
CREATE PROCEDURE GetAllWeekEnding
AS
Select convert(datetime, we) as we2 FROM tblArchive order by we2
GO
if i use the convert function in the procedure, i'll get an error msg when i run the code. this is the code i am using.
Dim MyConnection As SqlConnection = New SqlConnection(ConfigurationSettings.AppSettings("ConnectionStringSQL"))
Dim MyCommand As SqlCommand
MyCommand = New SqlCommand("GetAllWeekEnding", MyConnection)
MyCommand.CommandType = CommandType.StoredProcedure
MyConnection.Open()
Dim mydr As SqlDataReader = MyCommand.ExecuteReader()
While mydr.Read()
DropDownList1.Items.Add(mydr("we2"))
End While
mydr.Close()
MyConnection.Close()
the error message is: No accessible overloaded 'ListItemCollection.Add' can be called without a narrowing conversion
any ideas?

Hi everyone.
I know, I know, it should have been a datetime from the start...but here's the problem.
I'm trying to sort by my date field but because it looks like: "04/03/2004 12:14:21 PM" it's not ordering it properly using:
ORDER BY [Date]
Are there any work arounds for this? Is there some way of doing:
ORDER BY covert(datetime, [Date], 103) or something?
Cheers

how do you get it to sort correctly for the date? at the minute its sorting on the characters rather than actual date value
Code Snippet
INSERT INTO @TempItems (OrderID)
SELECT OrderID
FROM Orders o
INNER JOIN Customers c ON c.CustomerID = o.CustomerID
INNER JOIN Employees e ON e.EmployeeID = o.EmployeeID
ORDER BY
CASE @SortOrder --Order ASC
WHEN 0 THEN cast(OrderID as varchar(100))
WHEN 1 THEN cast(c.CompanyName as varchar(100))
WHEN 2 THEN cast(e.FirstName as varchar(100))
WHEN 3 THEN cast(o.OrderDate as varchar(100))
WHEN 4 THEN cast(o.RequiredDate as varchar(100))
WHEN 5 THEN cast(o.ShippedDate as varchar(100))
ELSE '1'

Year Month ProductName Date

2013 11 CDE 2013-11-01
Is there a way I can do it for all the columns of the existing table ??
