Hello;
I just did this the other day, so you are in luck :). Add a attribute to
your table/entity, set it¹s type as COLUMN, enter the column name you want
to pass to the function . Set the return type, in this case I used
VARCHAR2 and set the internal data type to String. Modify the properties
for the attribute and set the read property to the function you wish to
use. I used to_char(%P,¹DD MONTH YYYY¹), the %P represents the value to be
passed to the function, in this case DATEID. I set the value to ReadOnly,
so I did not have to enter a function to write a value in the DATEID field.
After it is all said and done it looks like this:
{
allowsNull = Y;
columnName = DATEID; (column that is going to be passed to
function)
externalType = VARCHAR2; (External type expected, in this case
VARCHAR2)
internalInfo = {"_nameInObjectStore" = "TO_CHAR(DATEID,'DD MONTH
YYYY')"; }; (This is the data you enter for your read function)
isReadOnly = Y; (Here it is readonly not updateable)
name = theDateAsString; (What you called the attribute)
readFormat = "TO_CHAR(%P,'DD MONTH YYYY')"; (This is the data
you entered for the read function)
valueClassName = NSString; (Internal Data Type)
width = 11; (External Width)
},
It is pretty easy, from the properties file it looks hard but it is not.
Change 2 things, set the readonly property and set the read format using %P
for the value that EOF should pass to your function. And WA-LA.
Thanks
Don
