Anyone heard of a utility that can be used to parse complex,
nested SQL statements and return a list of source table.column
elements? By source table.column elements I mean original table
names in cases where an alias is used (<alias>column) or when no
table name is supplied and a default table name is assumed.
I know there are 3rd party SQL parsers that build a tokenized
parse tree. But the effort to walk the trees generated by nested
SQL statements in order to determine source table.column names
seems significant.
Motivation: I'm documenting a very complicated Oracle application
and would like to track which table.column elements are being
used across scripts.
Thanks,
Malcolm
