SqlUtil Module

# Introduction

The SqlUtil module provides a high level database-independent API for working with database objects and SQL.

To use this module, use `"%requires SqlUtil"` in your code.

All the public symbols in the module are defined in the SqlUtil namespace

Major sections of this documentation:

- SQL Operations: working with database data (finding, updating, inserting, deleting, merging data, etc)
- Schema Management: working schema definitions (creating, modifying, aligning tables, functions, types, triggers, etc)

The SqlUtil module provides generic functionality and a framework for SQL operations and schema management, and in order to use the SqlUtil module with a particular database, a driver-specific module has to be available as well.

Currently the following driver-specific modules are available:

- MysqlSqlUtil: for working with MySQL databases
- OracleSqlUtil: for working with Oracle databases
- PgsqlSqlUtil: for working with PostgreSQL databases

The underlying driver-specific module is automatically loaded and used when required; the classes provided in the SqlUtil module provide a generic API that uses the driver-specific implementations for the underlying driver-specific implementation.
