speeding up full text indexing

February 24, 2006 Leave a comment
I was working with a database of 3 million records, where a full text index takes 3 days to complete
 
I found a gem of a stored proc, sp_fulltext_service ‘resource_usage’,5 it sped up the population to 9 hours!

Changing a default on a column on SQL

February 16, 2006 Leave a comment
If you set a default value to a column, then try to drop that column, in MS SQL, you sometimes get obscure errors like this.
 
Server: Msg 5074, Level 16, State 1, Line 1
The object ‘DF__question_v__type__50C5FA01’ is dependent on column ‘type’.
Server: Msg 4922, Level 16, State 1, Line 1
ALTER TABLE DROP COLUMN type failed because one or more objects access this column.
I have found that this can be fixed with this command:
 
alter table question_values drop constraint DF__question_v__type__4FD1D5C8
 
Where the table name would be changed to fit your own purposes.
