In some situations it is necessary to quickly add or remove histograms from a particular column (also known as column statistics.)
This article shows how to accomplish this with one command.
The commands given in this article will not affect column statistics currently gathered for other columns, they will only touch the specified column.
Column statistics can be:
- so called minimal consisting of just 1 bucket (2 endpoints) with min/max value information required by the Optimizer
- histograms with between 2 and 254 buckets (3 and 255 endpoints respectively)
- absent with no column information recorded in the data dictionary (not normally recommended)
