Fix incorrect index increment in SQL Server schema script parser

[prjanitor]

Bug Description

The SQL Server schema script parser had a logic error where i = +2 was used instead of i += 2 when detecting 'OR ALTER' tokens in CREATE statements.

Impact

This caused the parser to incorrectly set the index to 2 instead of adding 2 to the current index, resulting in incorrect token parsing for statements like:

CREATE OR ALTER TABLE dbo.MyTable (...)

Fix

Changed the assignment operator from = to += to properly increment the index by 2, skipping past the 'OR ALTER' tokens.

Testing

The fix ensures that when parsing CREATE OR ALTER TYPE/VIEW/PROCEDURE statements, the parser correctly advances past the 'OR ALTER' tokens and properly extracts the object type and fully qualified name.
