添加或删除表

功能概述

在创建模型时,一般会在向导中勾选一些数据表,而进入设计器后也经常需要增加或删除数据表。

在添加新表时,可以直接绑定已有的数据表也可以通过SQL查询的方式创建新表。

添加表

1. 单击设计画布上方的添加表

image

2. 输入新表的名称。

image

3. 绑定表。我们有两种方法可以绑定表,一是通过直接选择数据库中的表;二是通过 SQL 查询的方式来添加表。

如果选择,则选择数据库中所需的数据表,并验证。

image


如果选择SQL查询,则根据当前所连数据库的语法输入表达式语句,并验证。

image

type=info

提示

  • 所输入SQL查询语句的语法规则必须与所连数据源的语法规则一致,否则会验证失败,无法添加。

    • 如连接的是SQL Server数据源,输入的SQL查询语句语法规则必须符合SQL Server语法

    • 如连接的是Oracle数据源,输入的SQL查询语句语法规则必须符合Oracle的语法

    • ……

  • 如果使用的是 DB2 数据库,那么在使用聚合列时需要为列添加别名,否则将会预览失败。
