Get the records when entered value dd matches in dd/mm/yyyy instead of entering dd/mm/yyyy

What I have tried:

where tbl_MonthleyIntrest.DateTime = '13';

Solution 2

Try:
SQL

SELECT * FROM tbl_MonthleyIntrest WHERE DAY(tbl_MonthleyIntrest.DateTime) = 13

Ignore that - I read it as MySql, not MSSql.
Try:

SQL

SELECT * FROM tbl_MonthleyIntrest 
WHERE DATEPART(dd, tbl_MonthleyIntrest.DateTime) = 13

it says Conversion failed when converting date and/or time from character string.

Simple solution: don't store date values in strings - it always gives problems. Always store values in the most appropriate form: numbers go in INT or FLOAT, dates in DATE or DATETIME. If you don't, then you store up problems for later on, and your data starts to become unusable.
You could bodge round it in this case with SUBSTRING, but it's not recommended - you are just putting a band-aid on a broken leg...

for date time i am using as nvarchar(50)

OriginalGriff 14-Mar-16 5:33am

I guessed: don't.
It's inefficient in space terms (100 bytes instead of 8), and it creates loads of problems when you want to do something with it: sorting doesn't work, comparisons don't work, culture can't be taken into account, invalid dates are very possible, and so, on, and so on.
Change it now, before you get too much data in there, because the more data you get, the bigger a problem it becomes to fix when you finally decide it just isn't working. If it gets to production? It's a total PITA and can really muck you up...

thank you sir

You're welcome!

Member 12115746 14-Mar-16 6:08am

sir by nvarchar can we execute the above statment

OriginalGriff 14-Mar-16 6:12am

As i said: yes - use SUBSTRING - but it will cause you problems. It's a lot, lot quicker to fix the problem at source, rather than fix each symptom it causes as they come up...

Member 12115746 14-Mar-16 6:14am

just for learning sir can you show statement
