如何清空表格

Question

如何在SQLite中清空表格？

如果我执行“DELETE * FROM TABLENAME WHERE ID＆gt; 0”，则下次输入记录时ID不会从1开始。

Answer 1

要真正消除表格的所有痕迹，您必须删除它然后重新创建它。如果您特别担心AUTOINCREMENT列，则可以操纵the sqlite_sequence table进行重置。

Answer 2

DELETE FROM tablename;

DELETE FROM SQLITE_SEQUENCE WHERE name ='tablename';

Answer 3

DELETE FROM SQLITE_SEQUENCE WHERE NAME = 'TABLENAME'
