We can retrieve the query even we closed our query window in SQL without saving the script.
SELECT execquery.last_execution_time AS
[Date Time], execsql.text AS [Script] FROM sys.dm_exec_query_stats
AS execquery
CROSS APPLY sys.dm_exec_sql_text(execquery.sql_handle) AS execsql
ORDER BY execquery.last_execution_time
DESC
Above query provides a list of scripts and its time of execution in the last 24 hours.
This will be work for all
executed scripts not only a view or procedure.
