Dump sp_WhoIsActive to a table

monitor_active_sessions.sql

-- ████████ FILE: monitor_active_sessions.sql ████████  
-- 🎯 MISSION OBJECTIVE: Real-time monitoring of active SQL Server sessions.  
--    - If the table **does not exist**, create it.  
--    - If the table **exists**, append new data.  
--    - If you need a **hard reset**, uncomment the DROP TABLE line.  
--  
-- 🔧 USAGE:  
--    🎮 Execute in SSMS or a SQL Agent job for continuous ops.  
--    🔬 Uncomment DROP TABLE if you want to refresh the dataset.  

-- 🏗️ SYSTEM INITIALIZATION: Declare key variables  
DECLARE @schema NVARCHAR(MAX),  
        @createTableSQL NVARCHAR(MAX),  
        @destinationTable NVARCHAR(200)  

SET @destinationTable = N'temp_monitoring_output'  

-- 🛑 SAFETY SWITCH: Uncomment to **reset** the table before use  
-- PRINT '⚠️ Nuking the table. BOOM!'  
-- DROP TABLE IF EXISTS [dbo].[@destinationTable]  

-- 🕵️ DETECT IF TABLE EXISTS  
IF NOT EXISTS (SELECT 1 FROM INFORMATION_SCHEMA.TABLES WHERE TABLE_NAME = @destinationTable)
