主要是设置主键唯一性默认,自增,非空,下面这句定义是不可行的。

<addPrimaryKey columnNames="id,create_time" constraintName="pk_id_create_time" tableName="npp_event_tags"/>

改成id主键,

<column name="id" type="BIGINT" autoIncrement="true" remarks="主键id" >
<constraints primaryKey="true" nullable="false"/>
</column>

create_time不做主键,做索引

<createIndex indexName="index_create_time" tableName="npp_event_tags">
<column name="create_time"/>
</createIndex>
