Inbindvariable peeking (also known as bind peeking), the optimizer looksat the value in a bind variable when the database performsa hard parse of a statement. Whena query uses literals, the optimizer can use theliteral values to find the best plan. However, when a query uses bindvariables...
(1). Sql cursor是否open?如果是则跳到5) 这种情况即为no parse,为方便比较,我们也作为parse的一种类型 (2). cursor是否在session cache中(pga),如果存在,则跳到5)这种情况oracle专家tom称其softer soft parse (3). 进行syntax check和 semantic check,然后在shared pool的hash表中寻找,如果匹配到则跳到step...
2. Sql的执行过程和parse分类,oracle运行sql时,过程如下: (1). Sql cursor是否open?如果是则跳到5) 这种情况即为no parse,为方便比较,我们也作为parse的一种类型 (2). cursor是否在session cache中(pga),如果存在,则跳到5)这种情况oracle专家tom称其softer soft parse (3). 进行syntax check和 semantic che...
Whena query uses literals, the optimizer can use theliteral values to find the best plan. However, when a query uses bindvariables, the optimizer must select the best plan without the presence ofliterals in the SQL text. This task can be extremely difficult. By peeking at bind values the ...
If Oracle bind variables are used, however, the TKPROF output is more helpful. For example: INSERT INTO TABLE (A, B, C) VALUES ( :a1, :a2, :a3) call count cpu elapsed disk query current rows --- --- --- --- --- --- --- --- Parse 687 0.01 0.01 0 0 0 0 Execute 687...
Oracle introduced a new feature called adaptive cursor sharing (ACS) in Oracle Database 11g, to improve the plans that are selected for queries containing bind variables. This feature can result in more cursors for the same query containing bind variable
