create date strict(value a, template b, default c)
|
Group |
Parses a text a using format template b and creates a timestamp from these values.
Description of Parameters
|
Parameter |
Description |
|
a |
The text to be interpreted. Note: Instead of a String (intended use) a Date or Timestamp object is also tolerated here (even if this makes the use of the function pointless), but then parameter b must remain empty. Note: If a String cannot be interpreted with the format template b or if a Date or Timestamp object has an Empty Flag, an error occurs and parameter c controls the further behaviour of the function. |
|
b |
|
|
c |
(optional) Behaviour of the function if the text cannot be parsed as a date. See also parameter a. Default: empty |
Possible Values for Parameter c
|
Value |
Behaviour of Function |
|
now |
The current date will be returned. |
|
empty |
The Empty Flag is set. Internally, the field also receives the current date. However, because of the Empty Flag, the value is not visible. |
|
error |
The function terminates with an error. |
|
Other value |
Instead of the input value, this value will be used. If this text cannot be interpreted with b either, the function will terminate with an error. |
Examples
Current date of the example: 2011-10-20 15:33:23.0
Note: No date cannot be interpreted as a timestamp with any format template b and thus triggers an error. The further behaviour of the function is then controlled with parameter c.
