Introduction to RSqlParser

Methods

There are currently 4 methods in the package:

get_all_bind_variables: Get the bind variables in sql.
get_all_select_cols_with_alias: Get the names of the selected columns in the sql
get_all_subqueries: Get the subqueries in sql.
get_all_tables_with_alias:  Get the names of the tables with alias present in the sql

Note

This is a non-validating module. It expects syntactically correct sql statements.

Currently, it supports only SELECT statements.

get_all_subqueries does not return nested sub queries. To retreive nested subquery, the subquery of the main select query needs to be passed in this method again.
