如果另一个模式中的对象依赖于被删除的对象,那么应用默认的drop语句语义。

另外,发出所需的语句创建需要的对象,或者绑定包并向其他用户或组授予访问和使用这些对象的能力。
Also, issue the required statements to create the objects desired, or bind the package and grant the ability to access and use those objects to other users or groups.
因此,GRANT命令通常会出现在 DDL中的对象创建语句之后,如数据表。
Therefore, GRANT commands are often included in the DDL after objects, such as tables, are created.
当SQL语句引用对象时,如果没有指定模式名,那么也会隐式地加上调用者的授权ID。
When an object is referenced by an SQL statement, it is also implicitly qualified with the authorization ID of the issuer if no schema name is specified.
应用程序准备(编译)好一条语句之后,可以修改语句对象——表、索引、统计信息。
After a statement has been prepared (compiled) by the application, the statement objects — tables, indexes, statistics — can be altered.
当执行预编译语句时,IDS检测底层对象的变化,必要时重新准备(重新编译)语句。
When you execute a prepared statement, IDS now detects changes to underlying objects and re-prepares (re-compiles) the statement if needed.
如果DMLsql语句、触发器、视图或例程内引用了一个全局变量,将为语句或对象记录关于完全限定全局变量名的依赖关系。
When a global variable is referenced within a DML SQL statement or within a trigger, view or routine, a dependency on the fully-qualified global variable name is recorded for the statement or object.
选择操作之后,可以启动元数据浏览器,选择要进行查询的业务对象,也可以手动输入对象名称和soql语句。
After the operation is selected, you can either launch the metadata browser to select the business object that you want to query on, or manually enter the object name and SOQL statement.
注意一个函数赋值或对象赋值语句也是赋值语句,应该以分号结尾。
Note that an assignment statement which is assigning a function literal or object literal is still an assignment statement and must end with a semicolon.
实际上,该遍历表达式返回具有rdf:type谓词的所有语句的对象。
In effect, this traversal expression returns the objects of all statements with an RDF: type predicate.
MTK 2.0提供对以下语句、对象和数据的基本迁移支持
MTK 2.0 provides basic migration support for the following statements, objects, and data
ct在何处生成ddl语句由对象创建时间决定。
Where -ct generates the DDL statements according to object creation time.
要想进一步增强面向对象特性,可以将if语句的最后一小部分替换为Map,后者将EventType连接到EventHandler工厂对象。
It would be even more object oriented if you replaced the last bits of the if statement with a Map connecting EventTypes to EventHandler factory objects.
这不包括那些被用在对象定义,数组定义,var语句,和参数列表中的逗号分隔符。
This does not apply to the comma separator, which is used in object literals, array literals, var statements, and parameter lists.
通过使用Informix4GL丰富的语言支持,可以轻松地实现用户界面和业务逻辑,还可以在其中嵌入用于访问数据库对象的SQL语句。
Using Informix 4GL's rich language support, it is easy to implement the user interface and the business logic that might involve embedding the SQL statements to access the database objects.
