Sql query to insert datetime in SQL Server


Question

I want to insert a datetime value into a table(SQL Server) using the sql query below

insert into table1(approvaldate)values(18-06-12 10:34:09 AM);

But I get this Error msg. Incorrect syntax near '10'.

I tried it with the quotes

insert into table1(approvaldate)values('18-06-12 10:34:09 AM');

I get this error message Cannot convert varchar to datetime

Kindly help! Thanks.

You will want to use the YYYYMMDD for unambiguous date determination in SQL Server.

insert into table1(approvaldate)values('20120618 10:34:09 AM');

If you are married to the dd-mm-yy hh:mm:ss xm format, you will need to use CONVERT with the specific style.

insert table1 (approvaldate)
       values (convert(datetime,'18-06-12 10:34:09 PM',5));

5 here is the style for Italian dates. Well, not just Italians, but that's the culture it's attributed to in Books Online.

A more language-independent choice for string literals is the international standard ISO 8601 format "YYYY-MM-DDThh:mm:ss". I used the SQL query below to test the format, and it does indeed work in all SQL languages in sys.syslanguages:

declare @sql nvarchar(4000)

declare @LangID smallint
declare @Alias sysname

declare @MaxLangID smallint
select @MaxLangID = max(langid) from sys.syslanguages

set @LangID = 0

while @LangID <= @MaxLangID
begin

    select @Alias = alias
    from sys.syslanguages
    where langid = @LangID

    if @Alias is not null
    begin

        begin try
            set @sql = N'declare @TestLang table (langdate datetime)
    set language ''' + @alias + N''';
    insert into @TestLang (langdate)
    values (''2012-06-18T10:34:09'')'
            print 'Testing ' + @Alias

            exec sp_executesql @sql
        end try
        begin catch
            print 'Error in language ' + @Alias
            print ERROR_MESSAGE()
        end catch
    end

    select @LangID = min(langid)
    from sys.syslanguages
    where langid > @LangID
end

According to the String Literal Date and Time Formats section in Microsoft TechNet, the standard ANSI Standard SQL date format "YYYY-MM-DD hh:mm:ss" is supposed to be "multi-language". However, using the same query, the ANSI format does not work in all SQL languages.

For example, in Danish, you will many errors like the following:

Error in language Danish The conversion of a varchar data type to a datetime data type resulted in an out-of-range value.

If you want to build a query in C# to run on SQL Server, and you need to pass a date in the ISO 8601 format, use the Sortable "s" format specifier:

string.Format("select convert(datetime2, '{0:s}'", DateTime.Now);

Management studio creates scripts like:

insert table1 (foodate) values(CAST(N'2012-06-18 10:34:09.000' AS DateTime))
2015/06/10

you need to add it like

insert into table1(date1) values('12-mar-2013');
2013/10/24

No need to use convert. Simply list it as a quoted date in ISO 8601 format.
Like so:

select * from table1 where somedate between '2000/01/01' and '2099/12/31'

The separator needs to be a / and it needs to be surrounded by single ' quotes.

If you are storing values via any programming language

Here is an example in C#

To store date you have to convert it first and then store it

insert table1 (foodate)
   values (FooDate.ToString("MM/dd/yyyy"));

FooDate is datetime variable which contains your date in your format.
