Time Conversion

Posted By:      Posted Date: May 22, 2011    Points: 0   Category :ASP.Net
 

I have a table with Open and Close times (time(0))

It is in 24 hr format,

my first issue is getting the time to display at all

second I would like to convert to am pm

		SqlConnection SqlCon = new SqlConnection(Config.ConString);
		SqlCon.Open();
		SqlCommand SqlCom = new SqlCommand("SELECT * FROM CompanyLocationsHours WHERE LocationID = '" + LocationID + "' AND AccountTypeID ='1'", SqlCon);
		SqlDataReader SqlDR = SqlCom.ExecuteReader();
		if (SqlDR.Read())
		{
			MondayCommercial.Text = "Monday: " + Convert.ToString(SqlDR["MondayOpen"]) + " - " + Convert.ToString(SqlDR["MondayClose"]);
		TuesdayCommercial.Text = "Tuesday: " + Convert.ToDateTime(SqlDR["TuesdayOpen"]).ToString("hh:mm") + " - " + Convert.ToDateTime(SqlDR["TuesdayClose"]).ToString("hh:mm");
		}
		SqlCon.Close();
		SqlCom.Dispose();

This is my trial, but both labels show no data, yet there is data in the table,and I am pretty sure the string format hh:mm is not the correct way to convert 24hr to 12 hr.

Any help would be appreciated, thanks!

SQL error: Conversion failed when converting date and/or time from character string.

  
I hope someone can advise on the issue I'm having.

This SQL worked beautiful until I added in @startdt and @enddt and this section >> AND [Selldate] BETWEEN ' + @startdt + ' AND ' + @enddt + '

By adding in this condition, I now get the following error:

Msg 241, Level 16, State 1, Line 8
Conversion failed when converting date and/or time from character string.

I have tried changed variables to type = date and various iterations of date formatting, casting with no success. The date in the table is clean as a whistle.

(The CONVERT function is being used in setup for a PIVOT SQL which needs  VARCHAR for column headers)

Thanks in advance for your help, 
JR

declare @itemID varchar(20)
declare @startdt varchar(12)

Date Time conversion error

  

Hello all

I am trying to create a stored procedure that filters data from sql server by date but i get this error:

Conversion failed when converting datetime from character string.

my stored procedure is like:

CREATE PROCEDURE [dbo].[frRecordsUniqueBProductAndDatesSortedBDate]
(
	@productId int, 
	@dateFrom DateTime,
	@dateTo DateTime
)
AS
SET NOCOUNT ON;
DECLARE @sql nvarchar(4000)
DECLARE @productIdFilter nvarchar(10)
DECLARE @dateFromFilter DateTime
DECLARE @dateToFilter DateTime

SET @productIdFilter = Convert(nvarchar(10), @productId)
SET @dateFromFilter = Convert(DateTime, @dateFrom)
SET @dateToFilter = Convert(DateTime, @dateTo)

Set @sql = 
'select * from tableName where productId = ' + @productIdFilter +
' and myDate >= ' + @dateFromFilter + 
' and myDate <= ' + @dateToFilter


the parameters are passed to the stored procedures as dateTime variables from c# code...

any suggestions?

Round off time to the nearest minute

  
How would you round this up to the nearest minute? There isn't a built in function to do this so you have to use a little bit of maths to get there. There are 60 seconds in a minute. We already have 38 seconds on the clock. So we need to add on 60 - 38 = 22 more seconds.

Performance Tests: Precise Run Time Measurements with System.Diagnostics.Stopwatch

  
Everybody who does performance optimization stumbles sooner or later over the Stopwatch class in the System.Diagnostics namespace. And everybody has noticed that the measurements of the same function on the same computer can differ 25% -30% in run time. This article shows how single threaded test programs must be designed to get an accuracy of 0.1% - 0.2% out of the Stopwatch class. With this accuracy, algorithms can be tested and compared.

Data Types - Date and Time in SqlServer

  
Date and time values can be stored with either the DATETIME or SMALLDATETIME data type. The difference between the two is that SMALLDATETIME supports a smaller range of dates and does not give the same level of precision when accounting for time. The DATETIME data type can hold values from January 1st of 1753 to December 31st of 9999. The time is stored to the 1 three hundredths of a second and each value takes up 8 bytes of storage. The SMALLDATETIME data type can hold values between January 1st 1900 and June 6th of 2079. The time is tracked to the minute and each value takes up 4 bytes of storage. The majority of business applications can live happily with SMALLDATETIME, however, if you are in an environment where each second matters or you need to make estimates to the distant future (or past) then you have to resort to DATETIME. If you fail to specify the time when inserting a value into a DATETIME or SMALLDATETIME column, a default of midnight is used. If you fail to specify the date portion the default of January 1, 1900 is used.

.NET 4 Web Application Startup Time

  
I was chatting with Jonathan Hawkins and some of the folks on the ASP.NET team about performance and Jonathan mentioned the startup time for large ASP.NET applications is improved on .NET 4. There are some improvements in the CLR and in ASP.NET itself that helped. If you have a giant app, you should do some tests.

Date/Time Conversions Using SQL Server

  
There are many instances when dates and times don't show up at your doorstep in the format you'd like it to be, nor does the output of a query fit the needs of the people viewing it. One option is to format the data in the application itself. Another option is to use the built-in functions SQL Server provides to format the date string for you.
