您要查找的是不是:
- Deleting Rows in Result Sets 删除结果集中的行
- From there, you can leave data in result sets or opt to map each row in a result set to an object. 从那里,您可以把数据留在结果集或者选择把结果集中的每一行映射到一个对象。
- There are no detail rows in the result set. 结果集中没有明细行。
- This produces additional rows in the result set. 这将在结果集中产生额外的行。
- Use API functions or methods to fetch the rows in the result sets. 使用API函数或方法提取结果集中的行。
- Use this tab if you want to group rows in the result set. 如果希望对结果集中的行进行分组,可以使用该选项卡。
- Use this tab to restrict the rows in your result set. 使用该选项卡可限制结果集中的行。
- The DELETE statement is used to delete rows in a table. delete 声明常用来删除表中的数据。
- Inserting rows through a cursor, updating rows in a cursor, or deleting rows through a cursor are not replicated in passthrough mode. 直通模式下,不复制通过游标插入行、通过游标更新行或者通过游标删除行的操作。
- The following topics provide details on adding, editing, and deleting rows in data tables, and how to work with rows in various stages of an application. 下面的主题详细讨论了在数据表中添加、编辑和删除行以及如何在应用程序的不同阶段对行进行操作。
- Defines a cursor that reflects all data changes made to the rows in its result set as you scroll around the cursor. 定义一个游标,以反映在滚动游标时对结果集内的各行所做的所有数据更改。
- Subsequent call to mysql_fetch_row() would return the next row in the result set, or FALSE if there are no more rows. 依次调用mysql_fetch_row()将返回结果集中的下一行,如果没有更多行则返回FALSE。
- The rank value only indicates a relative order of relevance of the rows in the result set. 排名值仅指示结果集中各行相关性的相对顺序。
- The format of the rows in the result set is defined by the column-list of the SELECT statement. 结果集中各行的格式由SELECT语句的列状列表定义。
- CROSS APPLY applies nodes() to each row in the Instructions table and returns only the rows that produce a result set. CROSS APPLY将nodes()应用于Instructions表中的每行,并且仅返回生成结果集的行。
- There are also means to give scrollable cursors free access to any row in the result set. 这里还有一些使可滚动光标能够自由访问结果集中的任意行的方法。
- The size of a Cartesian product result set is the number of rows in the first table multiplied by the number of rows in the second table. 第一个表的行数乘以第二个表的行数等于笛卡尔积结果集的大小。
- Using the CUBE operator on a real-life hierarchy, such as yearly sales and quarterly sales, produces meaningless rows in the result set. 对诸如年度销售额和季度销售额之类的现实性层次结构使用CUBE运算符在结果集中生成的行毫无意义。
- Result sets from the queries can be cached in result tables and re-used as customized data marts. 查询得到的结果集可以缓存在结果表中并作为定制数据集市重新使用。
- CROSS APPLY applies nodes() to each row in the outer table, T1(rows), and returns only the rows that produce a result set when nodes() is applied to T1. Rows. CROSS APPLY将nodes()应用于外部表T1(rows)中的每行;并且仅返回在将nodes()应用于T1.;rows时生成结果集的行。
