index property
The (unique) index of this variable in the sql query. For instance, the
query SELECT * FROM tbl WHERE a = ? AND b = :xyz OR c = :xyz
contains
three Variable
s in its AST, but only two FoundVariables, where the
?
will have index 1 and (both) :xyz
variables will have index 2. We
only report one FoundVariable per index.
Implementation
int index;
