Query for Searching data 'from Date to Date'

Question

0.00/5 (No votes)

See more:

I am using ms-access as database backend, and visual studio 08 for frontend in windows application.

For a cashbook table, I have Date column whose data type is string so that I can store data in my custom format like '12 -Jan -2011' .

This value is coming from dateTimePicker.Text property.
I have used custom property of dateTimePicker.

It is working fine for insert, update and delete, but when I am running query to find data 'date between', it is not giving proper result.

what can be best option to resolve this problem with least modification ?
:confused::confused:

Solution 1

Date column has type is string (varchar, nvarchar, ...). So, when you select this column with between clause, SQL cannot select exactly the result which you want.

Notice that, between clause only apply to some datatype, such as DateTime, SmallDateTime, int,... (datetime and Number only).

Please cast Date column into datetime before querying

SELECT Date FROM CashBook WHERE cast(Date as datetime) BETWEEN '...a from date here' AND '...a to date here'

Sorry, I forgot you mentioned in Access :). In Access you can use CONVERT function to convert Date column

Your problem is specifically that you are using a string.
It will search between the values of the strings, not between dates.

You will need to convert the Date as a string to a Date as a Date.

Or, much easier, use one of the Date options to format the date properly, giving it's format in a Day Month Year style.

That would obviate the problem altogether.
