Convert flatfile column to Datetime

Question

Can anyone please help me, I have the following format that is coming in from a flatfile.

2013-12-30 00-20-18,114

I have to convert this as datetime

Answer 1

You're starting with a string of 2013-12-30 00-20-18,114 and you need to get it into a format SQL Server can handle. The unambiguous format would be 2013-12-30T00:20:18.114 but the Expression language isn't going to like the T there in the middle so we'll have to settle for 2013-12-30 00:20:18.114 as our end state.

Your problem then becomes, how do I manipulate the supplied string into that format. You can use a script task but there's no need to pull out the big guns for something like this. Because the Expressions in SSIS can be a bit of a pain to work with, I'm going to have several Derived Columns in my data flow to allow me to take small steps toward my end goal

OLE_SRC Date String

I have a basic query here to inject the supplied value

SELECT
    '' AS wtf

DER Split to parts

This Derived Column is going to create two columns: DatePart and TimePart. The end result is that I will split this column where the whitespace is.

DatePart is defined as SUBSTRING(wtf,1,10) so this strips the first 10 characters out of the string. TimePart is defined as LTRIM(RIGHT(wtf,LEN(wtf) - 10)) so it takes the remaining characters, sans leading whitespace.

DER Standardize

In this step, I'm going to make the time part into a standard format. I create a new column StandardTime and use the expression REPLACE(REPLACE(TimePart,",","."),"-",":")

DER Concat

Here I put the two columns back together again as a shiny new column called ConversionReady. This expression is DatePart + " " + StandardTime

Data Conversion

Here I cast my ConversionReady column to date [DT_DATE] datatype and call it Copy of ConversionReady because I'm lazy.

OLE DB Destination

I created a table and mapped my wtf to SourceValue and "Copy of ConversionReady" to ConvertedValue.

CREATE TABLE dbo.ConversionReady
(
    SourceValue varchar(30)
,   ConvertedValue datetime
);

What is up with all those derived columns? Doesn't that slow thing down?

No, not really. It certainly makes it easier to debug than trying to do it all in a single expression since you have no debugging capabilities for Expressions.

Answer 2

I had the same problem when i mixed Date and Time as above in a string and then i tried to convert it in to DateTime. It was not possible.

Then i did it seperatlly. And added the time in to date using Date Add function.
