You can extend the attributes available to you by adding your own
XML attributes and abstract data types to the datatypes.xml file.
You will need to modify the datatypes.xml file in the following
cases:
- When you want to change the actual size of an existing data type.
- When you want to restrict the length of the input for a particular
field on the UI. For example, say the data type allows the input to
be of length 20 but in the UI you want to restrict the length of the
input to just 10.
- When the existing data types does not meet your requirements and
you want to create a completely new data type.
You will need to modify the yfsdatatypemap.xml file in the following
case:
- When you have defined a completely new data type in the datatypes.xml
file and you want to define the mapping for this new data type in
the yfsdatatypemap.xml file.
Note: Alter Scripts would not be generated on changing the size
of CLOB datatype.
