It then scans the larger table, and performs the same hashing algorithm on the join column(s). It then probes the previously built hash table for each value and if they match, it returns a row. Nested Loops joins - Nested loops joins are useful when small subsets of data are being ...
Operation hashing a set of rows into groups for a query with a GROUP BY clause. HASH GROUP BY PIVOT Operation hashing a set of rows into groups for a query with a GROUP BY clause. The PIVOT option indicates a pivot-specific optimization for the HASH GROUP BY operator. HASH JOIN (These...
