How to reduce size of SQL Server table that grew from a datatype change

Question

I have a table on SQL Server 2005 that was about 4gb in size.

(about 17 million records)

I changed one of the fields from datatype char(30) to <

Alternatively, you could do a full table rebuild to ensure there's no extra data hanging around anywhere:

CREATE TABLE tmp_table();
GO
INSERT INTO tmp_table() SELECT  FROM ;
GO
DROP TABLE ;
GO
EXEC sp_rename N'tmp_table', N'';
GO
Of course, things get more complicated with identity, indexes, etc etc...
