DB/Reporting :: Search A Table, Confining To A Specific Date Range Based On A Date-time Column?

Jul 14, 2009

Would it be possible to search a table, confining to a specific date range based on a date-time column, and get a count of the 10 most used words in a particular var-char column excluding a list of words?All in SQL?Currently I am pulling out the records that match and sorting through the contents outside of SQL, I would think where I can do it directly on the server it would be more efficient.(SQL 2008)

Asp.net - Fixing Column Data Type And Duplicate Column?

Nov 30, 2010

This is my programs complete code, the only problem is i want to fix the amount of decimal places that show up in my gridview. The problem is if i do this on the asp side the location of the column gets thrown off and the column is duplicated. I figured if i just remade the table on the asp side it would work only problem is if i remove the sql for that particular column the asp side column cannot get data.

Asp.net - Manipulating The Date And Time From A Datetime Sql Server Type

Aug 25, 2011

I'm trying to create an auction site using asp.net. My auction's start date & time and end date & time are stored in my sql server 2008 r2 database as datetime types. I'm using vb.net. I'm trying to create a select statement in which I can query the date and time portion relative to the current date and time (so as to only display current ongoing auctions). I can successfully query the date portion using the Date.Now function, but the time is giving me a hassle. DateAndTime.Now doesn't work. I've even tried to separate the time and date in the database, but I still can't get an effective query. Here are two examples of code which I've tried:

How Does DotNet Handle Parametrized Dates Where Programmatic Date Has No Time But Sql Date Has Time

Jul 16, 2010

Thought I'd see if Stack overflow is quicker than me testing something while I get a thousand interruptions from other work :)

I'm updating an old VB net application and trying to refactor some of the logic as I go. The app looks for data from a single date across a few tables and writes that view to a file.

Writing the query in SQL I'd get the equivalent of

SELECT * FROM table
WHERE CAST(FLOOR(CAST(table.date AS float))AS datetime) = '15-Jul-2010'

Ideally I'd use

SELECT * FROM table WHERE date=@input

and add a date object as a parameter to a System.Data.SqlClient.SqlCommand instance

Are those two comparable? Will I get the results I expect?

Get Type Of Data Column?

Aug 7, 2009

The user enters information into a textbox and I would like to reflect these changes on the database. So say there is a value of 50 in the textbox and the user just deletes this and it is now "". When I try to update the database I receive an error as it expects a type of double. However, simple appending a 0 here when a value of "" is encountered will not work for me as I have a universal function to handle all of my updating needs. How would I go about determining the type of field I am dealing with (int, double, varchar) of the data table which I currently have in memory
