數(shù)據(jù)庫(kù) 關(guān)鍵字：
為了避免在數(shù)據(jù)庫(kù)表結(jié)構(gòu)設(shè)計(jì)過(guò)程中使用系統(tǒng)保留關(guān)鍵字我們必須知道數(shù)據(jù)庫(kù)存在哪些關(guān)鍵字，接下來(lái)會(huì)列出mysql、oracle、sqlserver三個(gè)數(shù)據(jù)庫(kù)各自的保留關(guān)鍵字。

此外，ISO 標(biāo)準(zhǔn)定義了保留關(guān)鍵字列表。 不要使用 ISO 保留關(guān)鍵字作為對(duì)象名和標(biāo)識(shí)符。 ODBC 保留關(guān)鍵字列表（如下表所示）與 ISO 保留關(guān)鍵字列表相同。
注意
ISO 標(biāo)準(zhǔn)保留關(guān)鍵字有時(shí)可能比 SQL Server 限制更多，有時(shí)則更少。 例如，ISO 保留關(guān)鍵字列表包含 INT。 SQL Server 不必將此區(qū)分為保留關(guān)鍵字。
Transact-SQL 保留關(guān)鍵字可用作數(shù)據(jù)庫(kù)或數(shù)據(jù)庫(kù)對(duì)象（如表、列、視圖等）的標(biāo)識(shí)符或名稱(chēng)。 使用帶引號(hào)的標(biāo)識(shí)符或分隔標(biāo)識(shí)符。 不限制將保留關(guān)鍵字用作變量和存儲(chǔ)過(guò)程參數(shù)的名
ODBC 保留關(guān)鍵字
保留了下列關(guān)鍵字以用于 ODBC 函數(shù)調(diào)用。這些關(guān)鍵字根本不約束 SQL 語(yǔ)法；然而，為確保與支持核心 SQL 語(yǔ)法的驅(qū)動(dòng)程序兼容，應(yīng)用程序應(yīng)避免使用這些關(guān)鍵字。
