Couple of questions

Hi All,

I have 3 questions. Some one kindly answer those.

1) If a table of size 50GB, having no indexes if we create an clustered index on that then what will be the size of that index?

2) If a table is published in replication and i want to modify one of the columns data type char(50) to Char(100). What is the procedure to do it?

3)To read the error logs from SQL server, we use XP_READERRORLOG apart from this any other query
