Validating date during insert operation in pl sql with examples

For example, 1999-12-12 .12345 - should be represented as 1999-12-12 .12345Z.is 100ns (seven digits for the fractional part of the seconds).ODBC string literals are mapped to the datetime data type.Any assignment operation from ODBC DATETIME literals into datetimeoffset types will cause an implicit conversion between datetime and this type as defined by the conversion rules. 1234567 ' AS time(7)) AS 'time' , CAST('2007-05-08 .YYYY is four digits, ranging from 0001 through 9999, that represent a year.

ss is two digits, ranging from 00 to 59, that represent the second. The following table lists the supported ISO 8601 string literal formats for datetimeoffset.

The detection of any invalid UTC or local (to the persistent or converted time zone offset) datetime value will raise an invalid value error.

For example, 9999-12-31 is valid in UTC, but overflow in local time to the time zone offset .

The following code shows the results of converting a DECLARE @datetimeoffset datetimeoffset(4) = '1912-10-25 .1277 10:0'; DECLARE @datetime2 datetime2(3)[email protected]; SELECT @datetimeoffset AS '@datetimeoffset', @datetime2 AS '@datetime2'; --Result @datetimeoffset @datetime2 ---------------------------------- ---------------------- 1912-10-25 .1277 1912-10-25 .12 --(1 row(s) affected) Conversions from string literals to date and time types are permitted if all parts of the strings are in valid formats. Implicit conversions or explicit conversions that do not specify a style, from date and time types to string literals will be in the default format of the current session.

The following table shows the rules for converting a string literal to the datetimeoffset data type.
