[RESOLVED] performance issue

I have a table with about 200,000 records. so last week i decided to reduce the size to optimize performance so i backed up the table using

Code:

---

select *into table_1 from table

---

after few days, i needed to restore data that has been deleted, so i renamed the tables
table_1 to table
and
table to table_1
then did a query to insert the the newly added records and consolidate both tables

Code:

---

insert into table  (a,b,c) select a,b,c from table_1 where datecreated > '02/08/2012'

---

Now that was all fine, but im just wondering if this would cause any indexing issues or corruptions. as i started to experiance performance and speed issues lately. i made sure there was no duplicates and ran
dbcc checktable ("products");
any suggestions ??

I believe when you did this:

select *into table_1 from table

Table_1 does not have the indexes table did. Check that and I think you will need to create them.

DBCC checktable just checks the integrity of the table. You will would want to check the index fragmentation. Are you querying the table that you did the select into? If so like Tyson said their no index on the table that was created with the select into cmd. For the index fragmentation everyone has their own opinion of when they data should be reorg or rebuild. Here are a few pages that give you some info

actually it was the PK that was missing. i created it and all seems to be back to normal now. Thanks for the info :)
