When AUTO_UPDATE_STATISTICS Doesn't Happen

  • Article

When your SQL Server database is set to have its statistics automatically updated, you will probably conclude that, whenever the distribution statistics are out-of-date, they will be updated before the next query is executed against that index or table. Curiously, this isn't always the case. What actually happens is that the statistics only gets updated if needed by the query optimiser to determine an effective query plan.

Question of the Day

Encoding URLs

I have this data in a table:

CREATE TABLE Response
( ResponseID INT NOT NULL CONSTRAINT ResponsePK PRIMARY KEY
, ResponseVal VARBINARY(5000)
)
GO
If I want to get a value from this table that I can add to a URL in a browser, which of these code items produces a result I can use?
