Database plays an irreplaceable role in the modern economy and is widely used in the business computing areas like Enterprise Resources Planning (ERP), Customer Relation Management (CRM), Supply Chain Management (SCM), and the Decision Support System (DSS).

Computation of structured data in the database mainly relies on SQL (Structured Query Language). SQL is the powerful, simple-to-use, and widely-applied database computing script. However, it has some native drawbacks: non-stepwise computation, incomplete set-lization, and no object reference available. Although almost all vendors have
introduced and launched some non-compatible solution, such as various stored procedure like PL-SQL, T-SQL. These improved alternatives cannot remedy the native SQL drawbacks.

esProc solves these drawbacks with more powerful computational capability, much lower technical requirement, and broader scope of application. It is a more convenient database computing scripts.

I have often seen a recommendation that using DISTINCT instead of GROUP BY is better from a performance perspective. DISTINCT is definitely a more readable alternative, but I wanted to test for myself as to what the truth was. To compare the performance of the two, I wrote the following simple queries. The query below helps in identifying the number of records that SQL Server will need to process. On my machine, when executed without the GROUP BY or the DISTINCT clause, the query generates records in excess of 380,000.USE AdventureWorks2012; GO SELECT COUNT(so1.object_id) FROM sys.objects AS so1
CROSS JOIN sys.objects AS so2 ; GO The queries below fetch the same information – one uses the GROUP BY whereas the other query uses a DISTINCT.USE AdventureWorks2012; GO --Clean the buffers and procedure cache DBCC DROPCLEANBUFFERS; DBCC FREEPROCCACHE; GO --Evaluate GROUP BY SELECT so1.object_id, FROM sys.objects AS so1 CROSS JOIN sys.objects AS so2 GROUP BY so1.object_id, ; GO --Clean the buffers and procedure cache DBCC DROPCLEANBUFFERS; DBCC FREEPROCCACHE; GO --Evaluate DISTINCT SELECT DISTINCT so1.object_id, FROM ...(Read whole news on source site)
