Error Casting String To Date
Oct 24, 2007
I have a Foreach loop container that I'm using to loop through a directory and copy files to a new directory. The file name contains the date and I need to compare the value to the current date to determine if the file should moved. I'm having a problem converting the string to a date.
I have a FileName variable of type string that is in this form: 200710221200_FileName_7001.log
I have a FileDate variable of type datetime that I'm trying to use the following expression on:
(DT_DBDATE)(SUBSTRING(@[User::FileName] , 1,4) +"-"+ SUBSTRING(@[User::FileName] , 5,2) +"-"+SUBSTRING( @[User::FileName] , 7,2))
Which is giving me the following error:
The expression "(DT_DBDATE)(SUBSTRING(@[User::FileName] , 1,4) +"-"+ SUBSTRING(@[User::FileName] , 5,2) +"-"+SUBSTRING( @[User::FileName] , 7,2))" has a result type of "DT_DBDATE", which cannot be converted to a supported type.
From the help files, it appears to me that the DT_DBDATE cast uses the form of yyyy-mm-dd. I'm not sure what I'm doing wrong. Any help is greatly appreciated.
Thanks!

Hi All
My brain has truned to mush at the moment.
:(
I want to sort on a char(5) column with data in it that looks like
01/07
05/02
06/01
12/01
07/98
so it comes out in the human date order.
e.g
07/98
06/01
12/01
05/02
01/07

I am selecting older legacy data from an AS400 mainframe that we still use. I am fairly new to constructing T-SQL statements so I hope I am doing this correctly. There is a table from the AS400 that has been setup with a field for TMONTH, TDAY, and TYEAR. Instead of having one field for a date, for some reason years ago this was set up this way.
I now have this statement in my SELECT statement and it is not working:
WHERE (CAST(OWNR.TMONTH + '/' + OWNR.TDAY + '/' + OWNR.TYEAR AS DATETIME) >= @startdate)
I am not getting a syntax error, however I am getting "Error Converting data type varchar to numeric. These fields on the AS400 are set up as numeric fields.
What do I need to do differently? Should I use a CONVERT instead and if so, how would I structure that statement.
Thanks for the help

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:

Hi,I'm trying to concatenate a Description (nchar(100)) and Date(datetime) as Description and my initial effort was just"...description+' '+open_date as description..." which throws a date/string conversion error; finally came up with a working string belowbut don't think it's the optimal way to do this - any suggestions?select (rtrim(description)+''+rtrim(convert(char(2),datepart(mm,open_date)))+'/'+convert(char(2),datepart(dd,open_date))+'/'+convert(char(4),datepart(yyyy,open_date))) as description fromoncd_opportunity where opportunity_id=?open_date is not a required field at the db level, but it is requiredon the form so it should not be null as a rule.

I've imported a CSV file into a table in SQL Server 2012. It's a large file, 140,000+ rows, so I couldn't covert it to Excel first to preserve the date format due to Excel's row limit. In the CSV file, there were 3 column with date data in "31-Aug-09" format, and the import automatically transformed these in "31AUG09" format (varchar(50)) in SQL Server. Now I need to convert these 3 columns from varchar to datetime so I could work with them in date format.
I've tried several things,e.g,
select
convert(datetime,
right(admdate,4)+left(admdate,2)+substring(admdate,3,3))
or
select
convert(datetime,
substring(admdate,6,4)+substring(admdate,1,2)+substring(admdate,3,3))
but keep getting the same error message (Msg 241) "Conversion failed when converting date and/or time from character string".

Using DTS package in 2000 version, I am dumping TXT file contents into SQL Table,
I have one column having date in format YYYYMMDD(20070929) and corresponding column in SQL is datetime, but it fails on data type mismatch.
I have no choice of making date column in SQL to string or Varchar etc,
is there any way to make that date column in SQL to convert the value upon transformation from format (YYYYMMDD) to M/DD/YYYY (9/29/2007).
many many thanks,

I asked this question below, but the answer was that the conversion will take place automatically, but I can't get that to happen. I have a flat file with an 8 position field that I identify as string (and I also tried date) that is yyyymmdd and it needs to go into the database field that is datetime format. IS there something I am doing wrong with the definition of it, or do I need to add some kind of conversion, and if so, what and how would that be done. I'm a dts Sql2000 expert, but the SSIS thing is driving me crazy. I have a ton of dts' to convert and the migration tool doesn't work because there are a lot of active X scripts in them. thanks for your help. Boston Rose

Hi,
I Have this simple convertion in a Script component
Dts.Variables("dateOfProcess").Value = CDate(lineMCF.Substring(30, 2) + "/" + lineMCF.Substring(28, 2) + "/" + lineMCF.Substring(24, 4))
this works fin in my development environment which has a spanish version of SQL Server and uses "DD/MM/YYYY" as date format.
but the production environment has an english version of SQL Server and "MM/DD/YYYY" date format, so the package crashes in this server.
How do I convert the string to date not depending on the SQL server language.
thanks.

I have a table in which a date value is stored as varchar.some of these values are stored ina dd/mm/yyyy format and other values are stored in a yyyy-mm-dd format..Now I wish to retrieve some data by querying between two dates. However I need to convert the varchar date value to datetime in order to do this but since the date value is in two different formats, the following doesn't work.
select date_value
from my_table
where CONVERT(DATETIME, date_value, 103) between @date1 and @date2
How can you convert the date value to datetime when its stored in mutiple formats. I can't change the table itself as I dont have admin privelages.

Hi,
Im having a problem with a SQL string. Im not that great a building them and just need a bit of help. For example, my table has many fields, the 2 i need to concentrate on are; "Date1", and "Date2", these fields are VarChar(8). I also have a webpage thats going to build a report, that has 2 textboxes in with 2 dates, these textboxes are being used as a Date range (From > To). When a user submits the form, the query needs select all dates similar to this kinda thing (from >= "Date1" and to <= "Date2") if that makes sense. My Date format is (DD, MM, YY) BTW.
Thank you
Help is much appreciated.

Hello,
I'm new to SQL Server and I have to finish a VB.Net program from an employee that has left the company.
I have a table with column 'vanafdatum' witch has datatype char but they stored only dates in this column ( like this: 13/09/2006).
When I try to run the next querie I receive an error message "The conversion of a char data type to a datetime data type resulted in an out of range datetime value".
This is the querie I try to run
SELECT MAX(CAST(vanafdatum AS datetime)) AS vanaf_datum
FROM tarieven
WHERE (vanafdatum <
(SELECT getdate()))
Is there any way I can cast the char datatype to a datetime datatype without getting this error.
I allready tried to change the data type from char to datetime, but doesn't work either.
A possible solution is to erase the column an manually fill in all the fields again in the data type datetime, but that seems a little stupid to do.
So I wonder if there is a solution that can change the data type for all rows in the database without losing any data.

I've got an ftp task that will be downloading a couple of files each night. today they're called
blah20060830blah
the date value in the middle changes each day. I'm trying to adjust this value with an expression. The expression doesn't want to cast my getdate function into a string that this property will accept. I know i'm missing something stupid.
Thank you

I'm using SQL 7.0 SP1.
I am using DTS to read in a date with the format of YYYYMMDD. I am trying to convert this date to MM/DD/YYYY and then use the CDate function with the following code to load it into a Datetime column in SQL Server:
Function Main()
strDate = DTSSource("Col002")
strYear = Left(strDate, 4)
strMonth = Mid(strDate, 5, 2)
strDay = Right(strDate, 2)
strHoldDate = strMonth + "/" + strDay + "/" + strYear
DTSDestination("DateName") = strHoldDate
Main = DTSTransformStat_OK
End Function
My DTS package will execute without errors, but it does not add the row. I have been successful using CDate when the source date is in the format MM/DD/YYYY.
Also, do you have any tips on how to debug DTS? How to see what's in a variable, etc.?
Thanks!
Lisa

I am running a converted DTS package which executes a stored procedure which extracts fields from a SQL database table and puts them to a flat file. Two of the fields are datetime fields. The stored procedure does not convert the dates, and under SQL 2000 DTS the fields extract as strings in format yyyy-mm-dd hh:mms. When this gave me an error in SSIS, I added a data conversion task between the Ole DB Source and the Text file destination to convert the two fields to DT_STR format and used the converted fields in my mapping for the text file. I am still getting an error on this:
-1071636319,0x,Data conversion failed. The data conversion for column "mm_hdr_process_date" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page."
The target code page is 1252 (ANSI) and I have tried several variations of length, and I still get this error.
Any suggestions? I would prefer not to have to change every stored procedure we have which may do this.
Thanks for any help.

Having some trouble converting strings to dates. I am using a .dtsx package and have figured out how to use a derived column to convert the string to a new string which is a valid date. The problem is now converting the column data type to date. I insert a new data conversion step to convert the vchar field to date, then when it runs it fails on this step. Error is
The conversion returned status value 2 and status text "The value could
not be converted because of a potential loss of data."
If I leave out the data conversion step and run the package, then manually change the data type to date it warns with the same message, but if I accept it converts correctly.
Here is my derived column code
REPLACE(SUBSTRING([Data Conversion 1].START_OF_EXECUTION,1,10) + " " +
RIGHT([Data Conversion 1].START_OF_EXECUTION,8),".",":")
Please Help

I created an SSIS package that pulls in legacy data from a DB2 AS400. There is an In Date field that is stored on the AS400 as OdbcType.Date or DATE. However, when I use SSIS to pull in the data, SQL wants it to be a string so I gave up and let SQL have it's way.
Now in my SELECT statement, I have this:
SELECT TLMST.TLNUMBER, TLMST.DOGNAM, BRDMST.BRDesc, TLMST.INDT
FROM TLMST INNER JOIN
BRDMST ON TLMST.BRDCOD = BRDMST.BreedNumber
WHERE (TLMST.INDT >= @startdate) AND (TLMST.INDT <= @enddate)
ORDER BY TLMST.INDT, TLMST.TLNUMBER
Because I see the dates stored in TLMST are yyyy-mm-dd format, this is not working. It is not pulling any records. I tried to use the CAST statement but I keep getting errors about casting from a string to a date and data overflow errors.
Should I go back and re-do the SSIS or is there a way to pull the records for this? Thanks for the information

EventStartDate is held as an varchar(10) therefore needs to be cast before i can compare. Is this the best way or is there a better one? If it is how do i get it to work?Any help would be great thanks,drazic19
