Hi,
I have a requirement to convert a date value like '7th March 2020' to '2020-03-07'.
However, the problem is the datatype for the date column is varchar and this needs to be achieved in SSIS.
Can somebody please help on this ?
Thanks.

What have you tried so far? I imagine if you replace the "th ", "nd " or "st " with " ", the CONVERT function in SSIS would be able to handle it, wouldn't it?

I've never much enjoyed building out these complex expressions in SSIS.

John's suggestion is correct, also just make sure you throw in "rd" as well.

I created a variable named "sDate" with a String Data type. It's value is set to "7th March 2020".

I used the following (quite lengthy) expression to convert this into the "YYYY-MM-DD" string format:

(DT_STR, 4, 1252) DATEPART("YEAR", (DT_DATE) REPLACE(REPLACE(REPLACE(REPLACE(@[User::sDate], "st", ""), "nd", ""), "rd", ""), "th", "")) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("MONTH", (DT_DATE) REPLACE(REPLACE(REPLACE(REPLACE(@[User::sDate], "st", ""), "nd", ""), "rd", ""), "th", "")), 2) + "-" + RIGHT("0" + (DT_STR, 2, 1252) DATEPART("DAY", (DT_DATE) REPLACE(REPLACE(REPLACE(REPLACE(@[User::sDate], "st", ""), "nd", ""), "rd", ""), "th", "")), 2)

Hopefully that helps as at least a starting point.

Recreating such a thing in yet another "string format" would go against my grain. Why not convert it to a proper DATE or DATETIME datatype?

RBAR is pronounced "ree-bar" and is a "Modenism" for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
________Stop thinking about what you want to do to a ROW... think, instead, of what you want to do to a COLUMN.

Change is inevitable... Change for the better is not.
