hi
The fieldtype function can tell the type of the field ( name, name value, attribute etc ) , what is the way to check the data type of a field?
We have a DFDL model, and when iterating through the element list, we want to be able to know the datatype of the element.
Regards

There's just a DFDL model and some ESQL code such as the following ..
Values from the DFDL are being used to create a queryString, now when an element is a float or a decimal , I need to be able to format it in a specific way .. I can't do that without knowing the data-type of the element ...
| Code: |
-- we take the element that is coming in
DECLARE refInp REFERENCE TO InputRoot.DFDL.atom:*;
-- we get to the first child
MOVE refInp FIRSTCHILD;
-- we iterate over all the children, making a query string
WHILE LASTMOVE(refInp) DO
SET FieldName = FIELDNAME(refInp);
SET FieldValue = FIELDVALUE(refInp);
CREATE LASTCHILD OF OutputLocalEnvironment.Destination.HTTP.QueryString NAME FIELDNAME(refInp) VALUE FIELDVALUE(refInp);
MOVE refInp NEXTSIBLING;
END WHILE;

Perhaps some sort of naming convention for the different data types?
blXXXX boolean
chYYYY char/string
inZZZZ integer
etc
etc
I can see what you are trying to do but IMHO there will always be exceptions so trying to do this universally is (again IMHO) doomed to fail.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions. |

Have you looked at FIELDTYPE?
