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...
Rapid Implementation for Oracle Student Management CloudConsiderations for Bind Variables in Table-Validated Value Sets After you assign a value set to a flexfield, you can use bind variables in the WHERE clause. These bind variables refer to flexfield elements: :{SEGMENT...
PLSQL_性能优化系列07_Oracle Parse Bind Variables解析绑定变量,使用绑定变量的重要性:如果不使用绑定变量而使用常量,会导致大量硬解析。由于硬解析的种种危害,不使用绑定变量往往是影响oracle性能和扩展性的最大问题
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 ...
