<p> 講了變量，現(xiàn)在也要講講“函數(shù)”和“子程序”了。 </p>
<p> 像“sin( )”、“abs( )”這些都是函數(shù)都是內(nèi)部函數(shù)，現(xiàn)在我們要來(lái)講講外部函數(shù)，外部函數(shù)和變量一樣在使用之前也是要先申明。它們的結(jié)構(gòu)如下圖所示。</p>
<p align="center"><img src="img/ac2k1606.gif" width="420" height="104" alt="函數(shù)結(jié)果">
</p>
<p align="center"><img src="img/ac2k1608.gif" width="400" height="188" alt="舉例" border="1"></p>
<p align="left"> <br>
函數(shù)則會(huì)把“a+b-c”的值返回給函數(shù)名“Getnumber”，如果我們輸入Getnumber(9,4,2)，則會(huì)返回“9+4-2”即“11”給函數(shù)“Getnumber”。“Function”的英文含意就是“函數(shù)”。它在這兒用來(lái)作為函數(shù)申明的一個(gè)內(nèi)容。在它后面跟著的就是這個(gè)函數(shù)的函數(shù)名。在這個(gè)函數(shù)名后面的括號(hào)中，列的是這個(gè)函數(shù)中的參數(shù)。每個(gè)函數(shù)之間要用逗號(hào)隔開(kāi)，并用“As”語(yǔ)句后跟“數(shù)據(jù)類型”來(lái)定義數(shù)據(jù)的類型。
括號(hào)外面的“As 數(shù)據(jù)類型”用來(lái)定義“函數(shù)名”的。它表示函數(shù)返回的數(shù)據(jù)的數(shù)據(jù)類型。 </p>
<p> 其實(shí)子程序和函數(shù)很相似，兩者結(jié)果對(duì)比如下圖所示。</p>
<p align="center"><img src="img/ac2k1607.gif" width="380" height="238" alt="兩者結(jié)果對(duì)比" border="1"></p>
<p> <br>
這兩種類型的過(guò)程都可以接收參數(shù)，函數(shù)可以返回單一的數(shù)據(jù)值，但子程序不能。另外，你可以從ACCESS中任何地方執(zhí)行一個(gè)函數(shù)，包括從查詢中的表達(dá)式中和宏中。然而你只能從一個(gè)函數(shù)、子程序或作為一個(gè)窗體或報(bào)表中的一個(gè)事件過(guò)程來(lái)執(zhí)行子程序。
