Besides, which is slower static SQL or dynamic SQL? Usually, Dynamic SQL is generally slower than static SQL because the database management system has to create an access plan at runtime for dynamic SQL statements.
In respect to this, what's the difference between static and embedded SQL?
In Static or Embedded SQL, how the database will be access procedure is predetermined in the embedded SQL statement and performed by the preprocessor where user cannot run queries on runtime. All processes including Parsing, validation, optimization and generation of application access plan are done at compile time.
And, what's the difference between run time and dynamic SQL?
1.In dynamic SQL, how database will be accessed is determined at run time. 2.It is less swift and efficient. 3.SQL statements are compiled at run time. 4.Parsing, validation, optimization, and generation of application plan are done at run time.
