PR Summary

• Addition of ColumnSchemaTest.php
  This update introduces a new test, specifically for checking how our system handles various types of data. The test will ensure that all information is processed and stored correctly.

• Minor modifications in QueryBuilderProvider.php and SchemaProvider.php
  The label 'time', used to identify a particular type of data column, has been renamed to 'datetime_col'. This change is being made to increase clarity and avoid any potential confusion in the future.

• Update in mssql.sql Fixture File
  In line with the changes made in the PHP files, the definition for the 'type' table in the fixture file has also been updated - the 'time' column is now known as 'datetime_col'.
