Extract SQL Server Table Meta-Data: Fields, Data Types, and Descriptions

If you need to extract meta-data from a SQL Server table, including fields, data types, and descriptions, there are several options available to you. One option is to use SQL Server Management Studio (SSMS), which has a built-in feature for generating scripts that include table meta-data.

Using SSMS to Extract Table Meta-Data

To use SSMS for this task, follow these steps:

  1. Open SSMS and connect to the SQL Server instance that contains the table you want to extract meta-data from.
  2. In Object Explorer, navigate to the database that contains the table.
  3. Expand the Tables folder and locate the table you want to extract meta-data from.
  4. Right-click the table and select Script Table as > CREATE To > New Query Editor Window.
  5. A new window will open with a script that creates the table. At the top of the script, you will see the meta-data for each field in the table, including the field name, data type, and any descriptions.
  6. Copy and paste the meta-data into a separate document or tool for further analysis or use.

Using T-SQL to Extract Table Meta-Data

If you prefer to use T-SQL to extract table meta-data, you can use the system views in the SQL Server instance's master database.

USE master;

SELECT 
  c.name AS 'Column Name', 
  t.Name AS 'Data Type',
  c.max_length AS 'Max Length',
  c.precision AS 'Precision',
  c.scale AS 'Scale',
  c.is_nullable AS 'Nullable',
  ISNULL(e.[value], '') AS 'Description'
FROM 
  sys.columns c
INNER JOIN 
  sys.types t ON c.user_type_id = t.user_type_id
LEFT OUTER JOIN 
  sys.extended_properties e ON e.major_id = c.object_id AND e.minor_id = c.column_id AND e.name = 'MS_Description'
WHERE 
  c.object_id = OBJECT_ID('your_table_name');

Replace "your_table_name" with the name of the table you want to extract meta-data from. This query will return a result set with the meta-data for each field in the table, including the field name, data type, max length, precision, scale, nullability, and any descriptions.

Conclusion

Extracting meta-data from a SQL Server table is a common task for database developers and administrators. Whether you choose to use SSMS or T-SQL to extract the meta-data, both methods are straightforward and can be easily customized to fit your specific needs.
