Row level security has supported in-memory OLTP tables. Users can now implement the Row-level security policy on the memory tuning table.
In addition, schemabinding, predicate functions, and inline table-valued functions include native_compilation compilation options.
One, make series horizontal single lineThis is a series of horizontal single test, the effect is good.In this example, the table main title tag Align=left|center|rightValign=top|bottom>Align and valign are used to set the horizontal and vertical positions of the headings respectively. The default value for align is top, which is the default value for Center;valign. The Rules= "None": indicates no internal border;rules= "Rows": a border that shows only horizontal orientation;Rules= "Cols: Indicat
