Describe the different types of costs and give examples of each. (a) Why is it important to separate out fixed and variable costs? (b) How does this help managers make decisions? How do a product cost and a period cost differ?
Under certain conditions the plan shown when using EXPLAIN PLAN can be different from the plan shown using V$SQL_PLAN. For example, when the SQL statement contains bind variables the plan shown from using EXPLAIN PLAN ignores the bind variable values while the plan shown in V$SQL_PLAN takes ...
evaluated only once for each set of differentvalues of the variables from its outer context. For UNCACHEABLE SUBQUERY, thesubquery is re-evaluated for each row of the outer context. Cacheability ofsubqueries is subject to the restrictions detailed in Section 7.9.3.1, “How theQuery Cache ...
Across the stable density stratification of the abyssal ocean, deep dense water is slowly propelled upward by sustained, though irregular, turbulent mixing. The resulting mean upwelling determines large-scale oceanic circulation properties like heat and
For DEPENDENT SUBQUERY, the subquery is re-evaluated only once for each set of different values of the variables from its outer context. For UNCACHEABLE SUBQUERY, the subquery is re-evaluated for each row of the outer context. When you specify FORMAT=JSON with EXPLAIN, the output has no ...
2.2.2. Correlation of TPC with HBA, HCA, and FLAV For the estimation models, the results of independent variables (HBA, HCA, and FLAV) reported in a previous work of our team [31] and the dependent variables (methods of analysis of the concentration of total phenolic compounds) were used...
For DEPENDENT SUBQUERY, the subquery is re-evaluated only once for each set of different values of the variables from its outer context. For UNCACHEABLE SUBQUERY, the subquery is re-evaluated for each row of the outer context. When you specify FORMAT=JSON with EXPLAIN, the output has no ...
However the explain plan below indicates the use of the RBO because the cost field is blank: SELECT STATEMENT [CHOOSE] Cost= The cost field is a comparative cost that is used internally to determine the best cost for particular plans. The costs of different statements are not really directly...
