Warning: Index "%1" on table "%2"."%3" might be corrupted because it references computed column "%4" containing a non-deterministic conversion from string to date. Run DBCC CHECKTABLE to verify index. Consider using explicit CONVERT with deterministic date style such as 121. Computed column indexes referencing non-deterministic expressions can't be created in 90 compatibility mode. See Books Online topic "Creating Indexes on Computed Columns" for more information.
