Tracking Down Past Queries in SQL Server Management Studio (SSMS)
Sometimes, you need to review previously run queries in SSMS. While SSMS doesn't have a built-in query history tracker, there are workarounds.
Finding Query History Data
If the SQL Server instance hasn't been restarted since running the query, the query plan might still be in the plan cache. Try this query:
SELECT t.[text] FROM sys.dm_exec_cached_plans AS p CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t WHERE t.[text] LIKE N'%<unique_query_identifier>%';
Replace <unique_query_identifier></unique_query_identifier>
with a portion of the query you remember.
If SSMS crashed and you lost your query history, check these recovery files:
<code>C:\Users\<username>\Documents\SQL Server Management Studio\Backup Files\</username></code>
Using Third-Party Tools and Tracing
For ongoing query history monitoring, explore tools like the SSMS Tools Pack. Alternatively, you can set up a lightweight SQL Server trace filtered by your login or hostname.
Detailed Query History with sys.dm_exec_query_stats
As Nenad-Zivkovic pointed out, using sys.dm_exec_query_stats
provides more comprehensive query history details. This query joins it with other system views to order results by last execution time:
SELECT t.[text], s.last_execution_time FROM sys.dm_exec_cached_plans AS p INNER JOIN sys.dm_exec_query_stats AS s ON p.plan_handle = s.plan_handle CROSS APPLY sys.dm_exec_sql_text(p.plan_handle) AS t WHERE t.[text] LIKE N'%<unique_query_identifier>%' ORDER BY s.last_execution_time DESC;
Remember to replace <unique_query_identifier></unique_query_identifier>
with a unique part of your query.

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
