I wanted to find out what data types SQL Server auditing was using, so I put the auditing file results into a temp table and executed tempdb..sp_help on that temp table to get the schema.
drop table if exists #myTempTable
select top 1000 *
FROM sys.fn_get_audit_file ('E:\sqlaudit*.sqlaudit',default,default)
exec tempdb..sp_help '#myTempTable'
This will give you the following results:
Here’s the expanded information on the temp table schema:
Then we can see what kind of data lives in the audit file. It helps you set up a table to hold auditing information making sure you won’t have the wrong data type or too short of a data type. I might not choose the same data type as the audit file, but at least it gives me an idea of what would be the best choice.
