Convert SSIS DateTime To A String

May 13, 2008

Being a newbie to SSIS I'm not sure of the most efficient method of converting a DateTime object to a String.

I'm from a C# background where this would be easy using DateTime.ToString("YYYYMMdd"). I want to use the date in a file name so don't require most of the parts.

I'm sure I could do this using a script task to produce a file name for each row of data in my table and add that filename to the dataset but it seem like overkill to do something that should be simple. Also as I'm supposed to be getting to grips with SSIS I shouldn't keep running back to what I know.

My current approach is to derive a column and build up an expression to convert the date into a string. The only problem being that it doesn't work.
The expression I'm working with is:
(DT_WSTR, 50)([OrgName] ) + "_" + (DT_WSTR, 50)( [PayrollName] ) + (DT_WSTR, 4)(YEAR( [ProcessedDate] )) + (DT_WSTR, 2)(MONTH( [ProcessedDate] )) + (DT_WSTR, 2)(DAY( [ProcessedDate] )) ".txt"

Can anyone see where I'm going wrong?

All comments greatly received.

Cheers
Ben

Convert Blob Data To String

Aug 25, 2006

How do I use the GetBlobdata to get the string representation?

I have tried numerous version of Encoders thinking that

System.Text.Encoding.GetEncoding(Row.TextData.ColumnInfo.CodePage).GetString(b) (where b is the byte array returned by GetBlobData)

But this doesn't work. I have had to resort to converting the field in SQL, so I don't have to deal with blobdata.

T-SQL (SS2K8) :: Using CAST Or CONVERT To Change Data From String To Datetime?

Apr 16, 2014

i am trying to take a field that has part of a date in it, so I have to parse it out as follows:

SUBSTRING(a1.Field1, 3, 2) + SUBSTRING(a1.Field1,5,2) + '20' + LEFT(a1.Field1,2)

This is because a date of 04/16/2014 will show as 160416 in the first part of the field I need to parse it out of, thus becoming 04162014.

From there I then need to convert this "date" into a legitimate SQL datetime type, so that I can then run a DATEDIFF to compare it to when the record was actually entered, which is a separate field in the table, and already in datetime format.

When I use the below statement, I am getting the message that, "Conversion failed when converting date and/or time from character string."

CAST((SUBSTRING(a1.Field1, 3, 2) + SUBSTRING(a1.Field1,5,2) + '20' + LEFT(a1.Field1,2)) as datetime)

I also tried CONVERT(datetime, (SUBSTRING(a1.Field1, 3, 2) + SUBSTRING(a1.Field1,5,2) + '20' + LEFT(a1.Field1,2)), and got the same message.

how I can parse that field, then convert it to a datetime format for running a DATEDIFF statement?

SIMPLE Command To Convert String To Number? Not CAST Or CONVERT.

Aug 15, 2006

Dear Experts,Ok, I hate to ask such a seemingly dumb question, but I'vealready spent far too much time on this. More that Iwould care to admit.In Sql server, how do I simply change a character into a number??????In Oracle, it is:select to_number(20.55)from dualTO_NUMBER(20.55)----------------20.55And we are on with our lives.In sql server, using the Northwinds database:SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2)) as a_number,cast ( STR(r.regionid) as int ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044SELECTr.regionid,STR(r.regionid,7,2) as a_string,CONVERT(numeric, STR(r.regionid,7,2) ) as a_number,cast (STR(r.regionid,7,2) as numeric ) as cast_to_numberFROM REGION R1 1.00112 2.00223 3.00334 4.0044Str converts from number to string in one motion.Isn't there a simple function in Sql Server to convertfrom string to number?What is the secret?Thanks

Convert Data Type In SSIS

Oct 1, 2007

Hi, all my friends,

This is another rookie one.

Is there a way in SSIS dev environment that will let you convert/cast data type at desing time?

Under data flow mappings, there are so many things you can do, but why I did not find any easy way to convert?

I got this validation warning about not supportng converting type DT_STR to DT_I4, or something related.

Am I missing something obvious?

Thanks!

DT_DECIMAL Vs DT_NUMERIC

Nov 21, 2007

Hi,

I've had problems with DT_NUMERIC in the past, where it chops off numbers and rounds them before they get to the database, even if you specify the exact same "Data Precision" and "Scale" as are defined in the table.

So, I did some tests with DT_DECIMAL and found that this data type does not do this.

I am trying to understand why the DT_DECIMAL data type does not allow you to change the "Data Precision," but DT_NUMERIC does.

I need to be able to set it to the equivalent of numeric(38,12).

Thanks

Numeric[DT_NUMERIC] - Comma Or Dot

Jun 18, 2007

Hi,



I have this problem:



In one SSIS project that I have, I convert (by using Data Conversion) my numeric column into Numeric[DT_NUMERIC] and get:



1.000000



Then, in another project I convert the same column again into Numeric[DT_NUMERIC] and get:

2,000000



Does anybody know how I can control if I´m using a dot or a comma?



Thank you.

SSIS String Variable Is Truncating Data

Sep 25, 2006

Greetings,


I have written a SSIS package which does the following:


- An 'Execute SQL Task' uses an OLEDB connection to execute a Stored Procedure in SQL Server 2005
A SSIS user defined variable named @SourceSQLStatement is passed to the Stored procedure as an OUTPUT
This variable is a string Data Type

- The Stored Procedure generates an SQL command and saves it in the variable
This variable is defined as @SourceSQLStatement nvarchar(4000) OUTPUT
The varible is then returned to the SSIS package


When the package is executed the variable does not contain the entire SQL command.
When I check in the Locals window during Debug, the contents seem to have been truncated:


+ User::SourceSQLstatement {SELECT a.FailureID, a.ExceptionHandlerID, a.FailureTypeCd, a.AccountNbr, a.AccountNm, a.CaseNbr, a.CustNm, a.AssociateNm, a.TargetSysNm, a.FailureDt, a.FailurePointTxt, a.SubmittedByNm, a.ErrorMsgTxt, a.CreateId, a.CreateDt, a.UpdateId, a.UpdateDt FROM GSPIntegrationException a WHERE a.CreateDt >= (select max(ETLC.RunDt) from X141572_ETLSTAGING.dbo.ETL ETL inner join X141572_ETLSTAGING.dbo.ETLControl ETLC on ETL.ETLID = ETLC.ETLID inner join X141572_ETLSTAGING.dbo.ETLRun ETLR on ETLC.ETLID = ETLR.ETLID an} String


The fully generated SQL command does not exceed the 4000 character length provided in the stored procedure.
Has anyone encountered this issue before?

Any help would be greatly appreciated

Thank You

Cannot Convert Between Unicode And Non-unicode String Data Types.

Apr 6, 2006

I have an Excel Source component hooked to an OLE DB Destination component in my SSIS 2005 Data Flow Task.  After I mapped the excel columns to the OLE DB table columns i get these errors below.  I noticed that for the first error, the Excel Field format (when you mouse over the column name in the mappings section in OLE DB component) is of type [DTWSTR] and the corresponding SQL field from my SQL table that it's mapping to is of type [DT_STR] when mousing over that field in the mappings in the properties of my OLE DB component.  All table fields in SQL Server for the table I'm inserting into are of type varchar.

SQL 2012 :: (SSIS) - Cannot Convert Between Unicode And Non-unicode Data Types

Sep 9, 2015

I have an SSIS package that pulls data from a MYSQL DB (Using RSSBus for Salesforce in SSIS to accomplish this). Most of the columns are loading properly, but I have many columns that I need to convert.

I have been using the Data Conversion dataflow task in SSIS to convert the rows.

I have 2 data conversions that work on most of the columns, but the DESCRIPTION column continues to return an error saying "Cannot convert between unicode and non-unicode types", regardless of what I choose on the Data Conversion task. So, basically I want to dump this column data into a SQL table with NVARCHAR datatypes. Here is what I am doing in my SSIS package...

1) Grab subset of data from SOURCE
2) Converts to TEXTSTREAM. (Data Conversion)
3) Converts to STRING. (Data Conversion)
4) Load Destination table. (OLE DB Destination)

I have also tried to simply convert the values to STRING, but that doesn't work either.

So, I have 2 Data Conversions working here that process most of the data correctly. What I can do to load the DESCRIPTION column?

Convert A String To Int?

Jul 10, 2014

using sql 2008, trying to convert a string to int

Example

Table1 has a varchar which i want to cast to int
00125000000 to int 125000000
i used the following
cast(B.[Assessment] as int) as [USER1_01],

with the result 125000000

Table2 has the same field in a different format.

0.00125

i need to find a way to convert one of them so they both match. if i did a join and matched the fields.

I tried

cast (10000000000 * cast([USER1_01] as NUMERIC(6,6)) as INT) as [USER1_01]

but for some reason it dosent look like they match, although they look the same. maybe a type problem?

How To Convert A Hex String To An Integer?

Feb 1, 2000

Hi folks,
I'm trying to import data from a text file (UnicodeData.txt) into
an SQL table. Some of the fields are unicode values (16 bits)
expressed as four hexidecimal digits. I've succeeded in importing
the data as character strings, but I have not found a way to convert
them into numbers. (They could be stored as int or nchar.)
I've tried convert(binary/int/whatever, string); E.g.
select convert(int, '0x1111') from import_unicode
gives the error
Syntax error converting the varchar value '0x1111' to a column of data type int.

I could write code to strip off one character at a time, convert the
hex digit to a decimal value, shift left, etc., but I find it hard
to believe that's the best way.

Any help is appreciated. Please email answer to lars_huttar@sil.org
as I don't read this board.

Thanks,

Convert String To Date In DTS

Dec 7, 1999

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
