Post SQL Assistant Hang - Reproducible Reply with quote
SSMS 10.0.5500.0
6.0.86 PRO

Code:
SELECT 'EXEC sp_rename ''' + c.TABLE_SCHEMA + '.' + c.TABLE_NAME
   + '.' + c.COLUMN_NAME
FROM INFORMATION_SCHEMA.[COLUMNS] c
WHERE c.DATA_TYPE = 'timestamp'


Start with the above. Add a + at the end of the select. Process hangs for a long time with one core pegged. Have about 20 tables in the database and only a few have a timestamp column. No other addins installed. Pasted this code in 3 times and hung each time.

I tried that and I can reproduce it as a long freeze. On my system it takes almost a minute for the cursor to start blinking again and nearly 100% of CPU

I will submit this issue to development for further analysis
