我想从Table2中删除我的行,其中ID存在于Table1中,而在Table1中,确定是否应该发生删除的值存在.
例:
表格1
+--------+--------+
| ID | Author |
+--------+--------+
| 121 | John |
+--------+--------+
| 150 | Ann |
+--------+--------+
表2
+--------+---------+-----------+
| ID | MetaKey | MetaValue |
+--------+---------+-----------+
| 121 | Color | red |
+--------+---------+-----------+
| 150 | Color | grey |
+--------+---------+-----------+
| 121 | Weight | 10 |
+--------+---------+-----------+
| 150 | Weight | 30 |
+--------+---------+-----------+
并删除Table2中的行,其作者是'John'(来自Table1)
