Introduction
In the world of managing databases, it's really important to know all the little details about your database.
Whether you're someone who manages databases, builds software, or just likes learning about tech, taking a closer look at your
Microsoft SQL Server (MSSQL) databases can help you understand how they're set up and how they work. In this blog, we'll break down a SQL query
that's meant to get important information about a specific database. We'll explain what each part of the query means and why it's important.
SQL Server Database Properties with T-SQL
This SQL query retrieves information from the
sys.databases dynamic management view, providing details about your database.
Let's break down the key components of the query:
select
database_id,
name,
create_date,
compatibility_level,
collation_name,
snapshot_isolation_state_desc,
is_read_committed_snapshot_on,
recovery_model_desc,
target_recovery_time_in_seconds,
is_auto_close_on,
is_auto_shrink_on,
is_auto_create_stats_on,
is_auto_update_stats_on,
is_auto_update_stats_async_on,
is_ansi_null_default_on,
is_ansi_nulls_on,
is_parameterization_forced
from
sys.databases
where
name = 'dbdocs'; --Replace this with your DBNAME
By executing this SQL query, you gain a comprehensive snapshot of various aspects of the 'dbdocs' database in your MSSQL environment.
Understanding these details is crucial for optimizing performance, ensuring data consistency, and maintaining database integrity.

database_id | ID of the database.
name | Name of the database.
create_date | Date the database was created.
compatibility_level | SQL Server compatible level.
collation_name | Default collation in the database.
snapshot_isolation_state_desc | Description of snapshot isolation transcations being allowed (OFF, ON, IN_TRANSISTION_TO_ON, IN_TRANSISTION_TO_OFF)
is_read_committed_snapshot_on | Is READ_COMMITTED_SNAPSHOT on (1) or off (0).
recovery_model_desc | Recovery model FULL, BULK_LOGGED, or SIMPLE.
target_recovery_time_in_seconds | The estimated time to recover the database in seconds.
is_auto_close_on | AUTO_CLOSE on (1) or off (0).
is_auto_shrink_on | AUTO_SHRINK on (1) or off (0).
is_auto_create_stats_on | AUTO_CREATE_STATISTICS on (1) or off (0).
is_auto_update_stats_on | AUTO_UPDATE_STATISTICS on (1) or off (0).
is_auto_update_stats_async_on | AUTO_UPDATE_STATISTICS_ASYNC on (1) or off (0).
is_ansi_null_default_on | ANSI_NULL_DEFAULT on (1) or off (0).
is_ansi_nulls_on | ANSI_NULLS on (1) or off (0).
is_parameterization_forced | Parameterization FORCED (1) or SIMPLE (0).
Conclusion
In conclusion, while this SQL query may appear complex at first glance, each component serves a specific purpose in providing valuable insights
into the configuration and behavior of your MSSQL database. By leveraging this information, database administrators and developers can
make informed decisions to enhance the performance and reliability of their database systems.
