PR Summary

• Added New Method for Data Insertion
  A new method, insertWithReturningPks, has been included in the Command.php file to enable storing of information with automatic assignment of a unique identifier.

• Refactored Data Management Code
  The DMLQueryBuilder.php file has been updated to improve code efficiency. This refactoring has simplified the use of the new method, insertWithReturningPks, and added a safety measure for scenarios where no unique identifier is assigned during data insertion.

• Removed Redundant Test Method
  Cleaning of the CommandTest.php file has led to the removal of the now unnecessary testInsertWithReturningPks method.

• Improved Query Builder for Tests
  Code in the QueryBuilderProvider.php file was modified to generate test SQL queries more efficiently while testing the insertWithReturningPks method.

• Added Negative Default Value Test
  A new test, testNegativeDefaultValues, has been set up in the SchemaTest.php file to verify the handling of negative default values.

• Updated Testing Database
  Changes to the mssql.sql file ensured that default values for some columns are negative numbers, to facilitate better testing of database mechanisms.
