can any one say me exactly when and where alias and context
are used in resolving a loop.
If possible try to give me a scenario also.
Answer Posted / vams_gk
when a schema contains a loop u should create alias
table..alias concept not only for loops.we can also use
in fantraps.
coming to context :when u run two sql statements as a
singlestatemnt we will go for context detection process.
in traps we can choose contexts.
traps are two types chasam trap and fan trap.
these traps are situvation oriented
relation betwen muliple tables like this:
--------------------------------------0-
chasam trap :1:M:1
fan trap :1:M 1:M
really if u want o see the context how to look
tools->automatic detection----.detect contexts in BO XIr2
