| Converting date to character in desired format |

I'm wanting to convert TxnDate in several tables to a character string, with a specified format.
For example, for a date of 2006-04-28, I want the data type to be SQL_CHAR (or SQL_VARCHAR) in the following format: 04/28/2006
Using the CONVERT() function, I'm able to convert the date to either SQL_CHAR or SQL_VARCHAR just fine. However, if I then try to use LEFT(), SUBSTRING() or RIGHT() on these results (to morph from 2006-04-28 to 04/28/2006), I'm getting BLANK results. For example, simply:
SELECT TxnDate as TxnDate, {fn LEFT({fn CONVERT(TxnDate, SQL_VARCHAR)},4)} as Temp FROM invoiceline NOSYNC WHERE TxnDate >= ({fn CURDATE()}-60)
Returns NOTHING in the 2nd column?!?!
How can I convert TxnDate into a character string of the format MM/DD/YYYY?
TIA! |

Well I'll start with showing everyone how to extract the Month, Day and Year so everyone can take what they want to do with the values from there.
SELECT TxnDate,
{fn MONTH("TxnDate")} as Month,
{fn DAYOFMONTH("TxnDate")} as Day,
{fn Year("TxnDate")} as Year
FROM invoiceline NOSYNC WHERE TxnDate >= ({fn CURDATE()}-60)

As always, thanks for the feedback.
However, I am curious why my approach would not work? If the CONVERT(..., SQL_VARCHAR) truly returns a varchar, why can't I then manipulate it with the other functions (LEFT(), RIGHT(), etc.)?
Also, using Month() and DayOfMonth() means I have to THEN convert to VARCHAR and manipulate even further. For example, the leading zero issue for Months and Days of Months less than 10 (e.g. I need 04/08/2006, rather than 4/8/2006).
Anyway, just don't understand why I can't simply use string functions after converting to a varchar?!?!? |
