5 years ago I wrote script SQL SERVER – 2005 – List All The Column With Specific Data Types, when I read it again, it is very much relevant and I liked it. This is one of the script which every developer would like to keep it handy. I have upgraded the script bit more. I have included few additional information which I believe I should have added from the beginning. It is difficult to visualize the final script when we are writing it first time. I use every script which I write on this blog, the matter of the fact, I write only those scripts here which I was using at that time. It is quite possible that as time passes by my needs are changing and I change my script. Here is the updated script of this subject. If there are any user data types, it will list the same as well.
SELECT s.name AS 'schema', ts.name AS TableName,
c.name AS column_name, c.column_id,
SCHEMA_NAME(t.schema_id) AS DatatypeSchema,
t.name AS Datatypename
,c.is_nullable, c.max_length, c.PRECISION,
FROM sys.columns AS c
INNER JOIN sys.types AS t ON c.user_type_id=t.user_type_id
INNER JOIN sys.tables ts ON ts.OBJECT_ID = c.OBJECT_ID
INNER JOIN sys.schemas s ON s.schema_id = ts.schema_id
ORDER BY s.name, ts.name, c.column_id
I would be very interested to see your script which lists all the columns of the database with data types. If I am missing something in my script, I will modify it based on your comment. This way this page will be a good bookmark for the future for all of us.
