SQLite Delete function syntax
Function:SQLite's DELETE query is used to delete existing records in the table. You can use a DELETE query with a WHERE clause to delete selected rows, otherwise all records will be deleted.
Syntax: DELETE FROM table_name WHERE [condition];
SQLite Delete function example
COMPANY 表有以下记录： ID NAME AGE ADDRESS SALARY ---------- ---------- ---------- ---------- ---------- 1 Paul 32 California 20000.0 2 Allen 25 Texas 15000.0 3 Teddy 23 Norway 20000.0 4 Mark 25 Rich-Mond 65000.0 5 David 27 Texas 85000.0 6 Kim 22 South-Hall 45000.0 7 James 24 Houston 10000.0 下面是一个实例，它会删除 ID 为 7 的客户： sqlite> DELETE FROM COMPANY WHERE ID = 7; 现在，COMPANY 表有以下记录： ID NAME AGE ADDRESS SALARY ---------- ---------- ---------- ---------- ---------- 1 Paul 32 California 20000.0 2 Allen 25 Texas 15000.0 3 Teddy 23 Norway 20000.0 4 Mark 25 Rich-Mond 65000.0 5 David 27 Texas 85000.0 6 Kim 22 South-Hall 45000.0 如果您想要从 COMPANY 表中删除所有记录，则不需要使用 WHERE 子句，DELETE 查询如下： sqlite> DELETE FROM COMPANY; 现在，COMPANY 表中没有任何的记录，因为所有的记录已经通过 DELETE 语句删除。
