SQL Server batch variables are lost between statements

[KIENKK-LP]

What happened?

Query

DECLARE @sn NVARCHAR(50) = '2404GQV000066A00105';

SELECT *
FROM serialnew
WHERE [S/N] = @sn;

SELECT *
FROM [v_wms_joined]
WHERE [S/N] = @sn;

SELECT *
FROM drm_report_n
WHERE [Serial number] = @sn;

SELECT *
FROM serial_existed
WHERE sn_code = @sn;

Actual behavior
TablePro reports:
Statement 2/5 failed: Must declare the scalar variable "@sn".
Expected behavior
The complete SQL Server script should be sent as one T-SQL batch, so
@sn remains available to all following statements. Each SELECT result
should still be displayed separately if possible.

Investigation
The query editor currently appears to split the script at semicolons using
SQLStatementScanner, then executes each statement separately. SQL Server
local variables only live within a single batch, so @sn declared in the
first statement is unavailable to later statements.
Relevant code:

Packages/TableProCore/Sources/TableProSQLGrammar/SQLStatementScanner.swift
TablePro/Core/Coordinators/QueryExecutionCoordinator+Parameters.swift
Plugins/MSSQLDriverPlugin/MSSQLPlugin.swift
SQLScriptText already has SQL Server-specific GO batch handling for
scripts, but that path does not seem to be used by the query editor.

Could you please review whether SQL Server query execution should preserve
T-SQL batches containing DECLARE, SET, IF, BEGIN/END, and similar
batch-scoped constructs?
