DROP SEQUENCE

DROP SEQUENCE 语句用于删除序列对象。

语法图

DropSequenceStmt ::=
    'DROP' 'SEQUENCE' IfExists TableNameList

IfExists ::= ( 'IF' 'EXISTS' )?

TableNameList ::=
    TableName ( ',' TableName )*

TableName ::=
    Identifier ('.' Identifier)?

示例

{{< copyable "sql" >}}

DROP SEQUENCE seq;
Query OK, 0 rows affected (0.10 sec)

{{< copyable "sql" >}}

DROP SEQUENCE seq, seq2;
Query OK, 0 rows affected (0.03 sec)

MySQL 兼容性

该语句是 TiDB 的扩展，序列的实现借鉴自 MariaDB。
