Hello everybody: I have a SQL Server intance with SP2. I want to modify the colum's order of one of my tables, which has 600.000 records. the time out property is set to 0 (unlimited). I open the desing view, (in multiuser or single user mode, the get the same result with both modes). With the mouse, for example, I move the fifth column to the second o seventh column position. SQL Server shows a warning telling me that this kind of operation with large amount of data can take very long time. I click ok. (continue) After a few seconds SQL Server shows a Time Out Error!!! (It seem like is SQL doesn't do anything) No event viewer o SQL Server error or warning is reported. It seems like if SQL Server ignores the time out=0 (or whatever configured). If I try the same procedure with less records, for example 250.000 the operations is successful [:S]. I thought it was RAM problem and upgraded my server from 2GB to 4GB I need to solve this issue but I would like to knwon which other method can I use to change the column order Plase help, any idea?? or documentation about it? Thank you in advance. HernÃ¡n Rojas.
