Can anyone explain the following code and also what is semantic load.
Previous(Sequence) as P1,
'Successor' as Relation,
Sequence as P2,
'Predecessor' as Relation
This is not giving any kind of error. This is example provided by Qlikview. Presidents.qvw. In that script it is written. Can u explain it what is happening ? I mean how predecessor and successor working ??
I did not notice it was semantic load
Find the definition from help.
Semantic Load * from abc.csv;
Semantic Select Object1, Relation, Object2, InverseRelation from table1;
You can go through the extract given in the book (Qlikview_Reference_Manual) at Page 385 of 942 to know about semantic load and their related examples.
Some of the extracts is as follows :
Semantic links are created by loading tables containing the relations between the objects.
values of the same field. A mixture between the two is not accepted.
show that it is not a logical table.
Normally four columns are used, the first one containing the field values that have a relation to some other
field value and the third one containing the related field value.
The second column must contain the names of the relations, and finally,
the fourth one must contain the names of the inverse relations.
If three columns are used, no explicit names for the inverse relations can be given. The names given in the
second column are used both for the relation and the inverse relation. The names are then preceded or followed
If the relations are between field values of the same field, the first and third columns must have the same
name. Also the names of the second and fourth column, i.e. the type of the relations, must be the same.
However,if the relations are between field values of different fields, all columns must have different names.
Please find the attachment for detailed understanding.
Thanks and Regards,
I was reading the page you referred for Semantic link. But htere i read that ":
"Semantic Links describe the relations between the objects rather than the objects themselves."
What does it mean ??
