Append 'WITH (NOLOCK)' to 'SQL' Queries, Get Packages in Active
Script
Description
Provides a suite of tools that can assist in enhancing the
processing efficiency of 'SQL' and 'R' scripts.
- The 'libr_unused()' retrieves a vector of package names that are called
within an 'R' script but are never actually used in the script.
- The 'libr_used()' retrieves a vector of package names actively utilized
within an 'R' script; packages loaded using 'library()' but not actually
used in the script will not be included.
- The 'libr_called()' retrieves a vector of all package names which are
called within an 'R' script.
- 'nolock()' appends 'WITH (nolock)' to all tables in 'SQL' queries. This
facilitates reading from databases in scenarios where non-blocking reads are
preferable, such as in high-transaction environments.
