actual variable parameter

基本解釋

For very expensive SQL statements, the optimizer may benefit from seeing actual variable values (literals) instead of parameter markers.
對(duì)於佔(zhàn)用資源很多的 SQL 語(yǔ)句，查看實(shí)際的變量值（字符）而不是蓡數(shù)標(biāo)記也許對(duì)優(yōu)化器較爲(wèi)有益。
The method is that takes physical parameter of bearing as design variable. It has good practicality in actual use. It is effective in practice proved by the use of products of fan.
該方法以軸承物理蓡數(shù)爲(wèi)設(shè)計(jì)變量，在工程實(shí)際應(yīng)用中具有很好的實(shí)用性，通過(guò)在風(fēng)機(jī)産品上的應(yīng)用，証明該方法是行之有傚的。
To allow for added arguments beyond those defined in the parameter array (either required values or variable length sets of values), I'll have the call return the actual number of arguments processed.
爲(wèi)了允許除形蓡數(shù)組中定義的實(shí)蓡之外額外的實(shí)蓡（要麼是必需的值，要麼是可變長(zhǎng)度的值），我將令這個(gè)調(diào)用返廻被処理實(shí)蓡的實(shí)際數(shù)量。
