49 as 49.00. and: 54.9 as 54.90. Regardless of the length of the decimal or whether there are are any decimal places, I would like to display a Decimal with 2 decimal places, and I'd like to do it in an efficient way. The purpose is to display money values. eg, 4898489.00

2021年1月13日 · I think you would most likely want to use '0.00' instead of '#.##'. The # will ignore trailing zeroes so 5.10 will become 5.1 or 4.00 will just show 4 on its own. The '0.00' format will ensure you always get exactly two decimal places. –

2018年1月13日 · Assuming the assignment is to exclude all strings that consist entirely of zero's, at most one decimal point and possibly leading and/or trailing spaces, here is one way to do it, which requires only standard string functions (and therefore should be faster than any regular-expression solution).

2014年12月5日 · Date and time expressed according to ISO 8601 is for example 2020-10-11T00:00:00+00:00 or 2020-10-11T00:00:00.000+00:00. Converting the ISO 8601 to java.util.Date is bit tricky. We can use the simpleDateformat API of java for the conversion.

select id from table where BadColumn='0000-00-00 00:00:00' Collect the IDs into a comma-delimited string. Example: 1, 22, 33. I used an external wrapper for this (a Perl script) to quickly spit them all out. Use your list of IDs to update the old columns with a …

The Z at the end specifies Zulu time which is UTC time and thus has a timezone offset of +00:00 hours.

2013年10月28日 · @Habib yes, that is correct if the current DateTime contains a timezone adjustment. If you don't want the timezone then use DateTime.Now.ToUniversalTime().ToString("O").
