You can drag and drop fields to make new tables, and to move fields between tables. You can also rename the tables, and set primary key fields.
既可以拖放字段形成新表，也可以在两表之间移动字段，还可以重命名表和设置主键字段。
An entity's primary key is the attribute or set of attributes that distinguish one instance of the entity from another.
实体的主键是使该实体的一个实例区别于其他实例的一个或一组属性。
The "id" column will be set as the primary key and will be auto-incrementing.

After an XMLToSQL is created, primary key columns and target columns are set. The following sample class illustrates these steps.
XMLToSQL创建完后，就可以设置主键列和目标列了。
As a result, if you rely on database sequences (such as for automatic primary key generation), it's likely that an identical primary key will show up across a set of databases.
因此，如果您依赖于数据库序列(如自动主键生成)，很有可能在一个数据库集中将出现同一个主键。
You can use dynamic relationships to correlate primary keys from a set of related business objects and static relationships to correlate non-primary key properties.
可以使用动态关系来关联一组相关业务对象的主键，而使用静态关系来关联非主键属性。
This method takes three parameters, the primary key, the action performed on the table (create, update, delete) and a result set.
此方法具有三个参数，主键、对表执行的操作(创建、更新、删除)和结果集。
Dynamic relationships are typically used to correlate primary keys from a set of related business objects, whereas static relationships are typically used to correlate non-primary key properties.
动态关系通常用于关联一组相关业务对象中的主键，而静态关系通常用于关联一些非主键的属性。
The ID is set to auto-increment and is used as the primary key.
ID被设置为自动增量并作为主键。
This is used to set the record's primary key and it serves as a signal to Doctrine that the record being processed already exists in the database.
这用于设置记录的主键，该主键用作针对Doctrine 的一个标记，表明正在处理的记录已经存在于数据库中。
Make a separate table for each set of related attributes, and give each table a primary key. Each field contains at most one value from its attribute domain.
为每个相关属性的集合创建一个单独的表，并为每个表指定一个主键。每列最多包含一个来自其属性域的值。
A column set to the AutoNumber data type often makes a good primary key.
设置为“自动编号”数据类型的列通常是很好的主键。
This model decomposes a nested relational schema into a set of atomic schemas, each of them constitutes of a primary key or a primary key plus a non-primary attribute.
此模型将复杂的嵌套关系模式分解为由主键或主键和一个非主属性构成的原子模式集合。
If the source table doesn't include a primary key or clustered index, the tool can automatically add a ROWID column and set the clustered index on the column during the conversion.
如果源表不包含主键或聚簇的索引，该工具可以自动添加rowid列和列上的聚集的索引设置转换过程中。
