sql - 显示表格最后一行的列？

Question

我在 sql 中有一个表，我想显示表的最后一行的列，这怎么可能？我用过SELECT TOP 1 id FROM .$table ORDER BY id DESC但没有答案。

Answer 1

• In MS Access:

  SELECT TOP 1 id FROM $table ORDER BY id DESC
  

• In MySQL:

  SELECT id FROM $table ORDER BY id DESC LIMIT 1
  

• In Oracle:

  SELECT id FROM $table WHERE ROWNUM <=1 ORDER BY id
  

• Or, you can do this: (based on Joop Eggen's comment)

  SELECT MAX(id) FROM $table
  

Where $table is the name of your table.

尝试将 LIMIT 设置为 1 喜欢

SELECT TOP 1 id FROM $table ORDER BY id DESC LIMIT 1

确保 $table 是您的表名。
