使用 SQL*Plus 命令 通过SQL Worksheet 可使用一组 SQL*Plus 命令。SQL*Plus 命令必须先由 SQL Worksheet 解释,然后再传递给数据库。一些命令不受支持,因此将被忽略,并且不会发送到 Oracle Database。有关不受支持的 SQL*Plus 命令的列表,请参阅 OTN 上的 SQL Developer。 1。 要使用“Describe”命令描述模式...
Oracle对SQL的处理过程如下所示: (1)语法检查(Syntax Check):检查此SQL的拼写是否正确。 (2)语义检查(Semantic Check):例如检查SQL语句中的访问对象是否存在及该用户是否具备相应的权限。 (3)对SQL语句进行解析(Parse):利用内部算法对SQL进行解析,生成解析树(Parse Tree)及执行计划(Execution Plan)。

When FIPS flagging is active, your SQL statements are checked to see whether they include extensions that go beyond the ANSI/ISO SQL92 standard. If any non-standard constructs are found, then Oracle Database flags them as errors and displays the violating syntax. ...
一、sql解析 这里我们先简单sql语句执行步骤: 语法检查(syntax check) 语义检查(symantic check): 对象是否存在,是否有权限。 sql解析(parse): 利用内部算法对sql进行解析,生成解析树及执行计划。 执行sql,返回结果(execute and return) 首先了解一下sql解析时用到的内存结构——shared pool。
