table variables, SQL Server is not generated by the log, and in the temporary table is generated log; 2 in the table variable, is not allowed to have nonclustered index; 3 The table variable is not allowed to have default defaults, also does not allow constraints; 4 The statistical information on the temporary table is sound and reliable, but the statistical information on the table variable is unreliable; 5 There is a mechanism for locking in th

Today in the group saw someone asked this question, then I summed up the knowledge to share it with you.

[Fngetdistance] --latbegin begins longitude. --lngbegin Start Dimension (@LatBegin Real, @LngBegin Real, @LatEnd Real, @LngEnd Real) Returnsfloat As BEGIN --distance (km) DECLARE @Distance Real DECLARE @EARTH_RADIUS Real SET @EARTH_RAD

CLUSTERED: Clustered index. Nonclustered index: nonclustered. Clustered is the physical implementation of data ordering, and the same table can only have one clustered index, and nonclustered is the logical sort. Microsoft's SQL Server supports two types of indexes: Clustered index and nonclustered index. The clustered index stores data in a data table in a physical order. Because there is only one physical order in a table, there can be only one c
