PL/SQL
PL/SQL是一種高級(jí)數(shù)據(jù)庫(kù)程序設(shè)計(jì)語(yǔ)言,PL/SQL語(yǔ)言在將SQL語(yǔ)言的靈活性及功能與第三代語(yǔ)言的可配置能力相結(jié)合方面是獨(dú)一無(wú)二的。該語(yǔ)言集成了面向過(guò)程語(yǔ)言的過(guò)程結(jié)構(gòu)和強(qiáng)大的數(shù)據(jù)庫(kù)操作，為設(shè)計(jì)復(fù)雜的數(shù)據(jù)庫(kù)應(yīng)用提供了功能強(qiáng)大、健壯可靠的程序設(shè)計(jì)語(yǔ)言。該語(yǔ)言專(zhuān)門(mén)用于在各種環(huán)境下對(duì)Oracle數(shù)據(jù)庫(kù)進(jìn)行訪問(wèn)。由于該語(yǔ)言集成于數(shù)據(jù)庫(kù)服務(wù)器中，所以PL/SQL代碼可以對(duì)數(shù)據(jù)進(jìn)行快速高效的處理。
PL/SQL is Oracle's procedural extension to industry-standard SQL. PL/SQL naturally, efficiently, and safely extends SQL. Its primary strength is in providing a server-side, stored procedural language that is easy-to-use, seamless with SQL, robust, portable, and secure.
