First I tried inserting values as below,

Answer 1

I had this issue when trying to concatenate getdate() into a string that I was inserting into an nvarchar field.

I did some casting to get around it:

 INSERT INTO [SYSTEM_TABLE] ([SYSTEM_PROP_TAG],[SYSTEM_PROP_VAL]) VALUES 
   (
    'EMAIL_HEADER',
    '<h2>111 Any St.<br />Anywhere, ST 11111</h2><br />' + 
        CAST(CAST(getdate() AS datetime2) AS nvarchar) + 
    '<br /><br /><br />'
   )

That's a sanitized example. The key portion of that is:

...' + CAST(CAST(getdate() AS datetime2) AS nvarchar) + '...

Casted the date as datetime2, then as nvarchar to concatenate it.

Answer 2

Simple answer - 5 is Italian "yy" and 105 is Italian "yyyy". Therefore:

SELECT convert(datetime,'21-02-12 6:10:00 PM',5)

will work correctly, but

SELECT convert(datetime,'21-02-12 6:10:00 PM',105)

will give error.

Likewise,

SELECT convert(datetime,'21-02-2012 6:10:00 PM',5)

will give error, where as

SELECT convert(datetime,'21-02-2012 6:10:00 PM',105)

will work.

Answer 3

convert(datetime2,((SUBSTRING( ISNULL(S2.FechaReal,e.ETA),7,4)+'-'+ SUBSTRING( ISNULL(S2.FechaReal,e.ETA),4,2)+'-'+ SUBSTRING( ISNULL(S2.FechaReal,e.ETA),1,2) + ' 12:00:00.127')))  as fecha,
