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)于占用資源很多的 SQL 語(yǔ)句，查看實(shí)際的變量值（字符）而不是參數(shù)標(biāo)記也許對(duì)優(yōu)化器較為有益。
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.
該方法以軸承物理參數(shù)為設(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)產(chǎn)品上的應(yīng)用，證明該方法是行之有效的。
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.
為了允許除形參數(shù)組中定義的實(shí)參之外額外的實(shí)參（要么是必需的值，要么是可變長(zhǎng)度的值），我將令這個(gè)調(diào)用返回被處理實(shí)參的實(shí)際數(shù)量。
