SQL Server converts the string 2018 to January 1st, 2018:
#Convert string to date in sql server insert statemnet how to
The following example shows how to convert a string to a date: SELECT CAST( '2018' AS DATE) In case the function fails to convert, it issues an error, depending on the implementation of a specific database system. The CAST() function returns a DATE value if it successfully converts the string to date. In this syntax, the string can be any DATE value that is convertible to a date. The following illustrates the syntax of the CAST() function: CAST (string AS DATE)Ĭode language: SQL (Structured Query Language) ( sql ) SQL provides a CAST() function that allows you to convert a string to a date. Convert string to date using CAST() function Hope this saves you time.Summary: in this tutorial, you will learn various functions that convert a string to a date in SQL. Tested it on 1000s of string dates in my system. NET Datetime.ToString(.) back into SQL datetime. I found this article useful in creating my function that converts string values from.
#Convert string to date in sql server insert statemnet iso
The best option is to stick to a deterministic setting, my current preference are ISO formats ( 12, 112, 23, 126), as they seem to be the most standard for IT people use cases. Date conversionsīecame dependent on SET LANGUAGE and SET DATEFORMAT starting with Implicit date conversions became nondeterministic. Starting with SQL Server 2005 and its compatibility level of 90,
#Convert string to date in sql server insert statemnet full
The specific format number they showed from 0 to 131 may vary depending on your use-case (see full number list here), the input number can be a nondeterministic one, which means that the expected result date isn't consistent from one SQL SERVER INSTANCE to another, avoid using the cast a string approach for the same reason. However, there's one contribution I'd like to make.
The most upvoted answer here are guravg's and Taptronic's. You can't use native T-SQL to determine whether is June 9th or September 6th. You still need to have that other crucial piece of information first. SELECT TRY_PARSE(' 10:06:32 PM' AS DATETIME USING 'en-gb')
#Convert string to date in sql server insert statemnet update
UPDATE for SELECT TRY_PARSE(' 10:06:32 PM' AS DATETIME USING 'en-us') Then you can write a case/switch for as many wacky non-standard formats as you want. this can be made fairly trivial by implementing your own CLR function. Until Denali, though, I think that has the best advice so far. No matter how much you try to predict your users' behavior, they'll always figure out a dumber way to enter a date that you didn't plan for. If someone enters is that August 9th or September 8th? If you make them pick a date on a calendar control, then the app can control the format. The days of letting people type dates using whatever format they want into a freetext form field should be way behind us by now. I strongly encourage you to take more control and sanitize your date inputs. returns an error if the conversion fails: SELECT N'MMM-dd/yyyy HH:mm:ss') AS DATETIME) Net's format, so most if not all of the token formats you'd expect to see will be there. The FORMAT() function and can also accept locales as an optional argument - it is based on. Here is one example using something you posted in your own answer. But you still can't just pass any arbitrarily defined wacky date string and expect SQL Server to accommodate.
In SQL Server Denali, you will be able to do something that approaches what you're looking for.
'mon dd yyyy hh:miAM (or PM)' as OutputFormat It wont be hard to adapt: Declare datetime It formats dates and/or times like so and one of these should give you what you're looking for.
