I am trying to convert a datetime column from my SQL Server to date in my vb.net program. I am importing my column with a SQL query from my vb.net source but I don't know how to convert it to date? Any ideas?
adapter_view.SelectCommand.CommandText = "SELECT [action_date] from table_1"
The thing is that my columns has hours minutes etc I want to get only the date from that column.
CONVERT(varchar,b.[Action Date],101) as Action_Date
With that code i convert my datetime to date format
SELECT CONVERT(varchar(10),Action_Date,101) as Action_Date from Table

I am trying to convert a column FC_FROM_DATE containing decimal values (ex. 20,200,721) into a date format 2020/07/21.
I have tried this code
SELECT TO_DATE(CHAR(CAST(FC_FROM_DATE AS DECIMAL(8,0))), 'YYYY/MM/DD')
FROM MARKETS.FORECAST
I get an error
Argument for chr should be between 0 and 127
Would much appreciate your help!
If you are using Oracle then you can use the following query:
SELECT TO_DATE(CAST(FC_FROM_DATE AS VARCHAR(8), 'YYYY/MM/DD') FROM Table
Seeing as the persisted format is YYYYMMDD you could convert the value to a varchar(8) and then use CONVERT to get a Date instance.
SELECT CONVERT(DATE, CAST(FC_FROM_DATE AS VARCHAR(8))) FROM MARKETS.FORECAST
Ideally Dates are stored as Date and a Date with a time component is stored as DATETIME2 (or equivalent if not Sql Server).
Test of the code above
DECLARE #FC_FROM_DATE decimal(8,0) = 20200721
SELECT CONVERT(DATE, CAST(#FC_FROM_DATE AS VARCHAR(8)))
2020-07-21
Disclaimer: This works in MS Sql Server.
I am bit confusing here?
declare #date1 datetime = '2016-01-21 14:10:47.183'
I want to convert '2016-01-21 14:10:47.183' To '21-01-2016'
when I tried: select convert(date,#date1,105)
I am getting: 2016-01-21
But with: select convert(varchar(10),#date1,105)
I am getting: 21-01-2016
Why I am not having same results with above code?
Why should I convert to varchar?
Thanks in advance
This is just presentation matter and should be done in application layer. If you cannot do it in application you could use FORMAT (SQL Server 2012+):
declare #date1 datetime = '2016-01-21 14:10:47.183'
SELECT FORMAT(#date1, 'dd-mm-yyyy');

Why I am not having same results with above code?
select convert(date,#date1,105)
-- DATETIME -> DATE
-- vs
select convert(varchar(10),#date1,105)
-- DATETIME -> VARCHAR(10) using specific style
If you only to skip time part use SELECT CAST(#date1 AS DATE) and do not bother how it is presented. It is still DATE.
To sum up: in SQL query use DATE as date, in application display it with desired format.
The reason why is because once you put a value in a datetime column (or date or any of the other variations on date-time datatypes) in SQL Server. SQL Server ceases to think of that date as having any particular format. It translates it into numbers, and stores it that way internally.
So when you select a date from a date time column, SQL Server displays it in the default format that you have selected based on your environment/local settings.
If you want to display it in any other format, you have to first convert it to a string, because as far as SQL Server is concerned, dates don't have formats. They are just numbers. The 21st day of March is the 21st day of March, whether you write it as 3/21 or 21/3.
So when you try to convert a date to a date with a different format, SQL Server just ignores you because dates don't have formats. However, if you want to convert that date to a string, SQL Server will be happy to help you display that string in any format you like.
Hope this helps, but sounds like some further research into how SQL Server stores dates would help your understanding.
I have created a package in |SSIS 2012. The package basically connect to a text files in a predefined location and load data from the text files to the SQL database table. I have one DOB field which is DATE TYPE in the destination SQL table and it was returning error: conversion failed and date out-of-range.
I did not have any luck converting DOB column using the CAST or CONVERT funtion:
CONVERT(date, DOB, 103)
What am I doing wrong?
You should use CAST() or CONVERT() functions, when you want convert varchar value to datetime
https://msdn.microsoft.com/ru-ru/library/ms187928.aspx
I had some bad data in my input files for the DOB column. For example, DOB: 100-01-01, 29999-05-24; I tried to convert these dates using CONVERT function and it was returning error.
So, I was just selecting records only with valid DOB dates using the query as below and after that I could convert the DOB without any error in this case:
SELECT * FROM MyTableTest WHERE ISDATE(dob) <> 1
I have created a column of datetime type in SQL Server.
The output of this column is:
1994-01-10
But I want to show only year, like this: 1994 (not long datetime)
How can I change this format type of datetime?
My table is tbl_borrowing, my column is VitiBotimit
Thank you
How about this:
SELECT YEAR(VitiBotimit)
FROM dbo.borrowing
DATETIME in SQL Server has no format - it's an 8-byte binary value - and therefore you cannot change the format.
You only get a format (of your choice) when you select the value from the table. If you only need the year - select it that way.
How to get the formatted date in SQL Server CE?
I have a column on a table that contains Date, but the column type is nvarchar
ID Date
----------------------
1 05/08/2012
2 10/08/2012
3 05/10/2012
The date format is MM/dd/yyyy, but it is in nvarchar.
Also, I want to have a WHERE clause to select the ID on a specific date. How can I do that? This is for SQL Server CE. Thank you very much.
you need to cover it use convert or cast function ...
cast(datecolumn as DateTime)
or
CONVERT(datetime,datecolumn,101)
For current date, you can use:
SELECT CONVERT(nvarchar,GETDATE(),101)
Output: (As of answered date)
05/31/2016
