processInsertSelect

protected void processInsertSelect(net.sf.jsqlparser.statement.select.Select selectBody,
 String whereSegment)

处理 insert into select

进入这里表示需要 insert 的表启用了多租户,则 select 的表都启动了

参数:

selectBody - SelectBody

appendSelectItem

protected void appendSelectItem(List<net.sf.jsqlparser.statement.select.SelectItem<?>> selectItems)

追加 SelectItem

参数:

selectItems - SelectItem

getAliasColumn

protected net.sf.jsqlparser.schema.Column getAliasColumn(net.sf.jsqlparser.schema.Table table)

租户字段别名设置

tenantId 或 tableAlias.tenantId

参数:

table - 表对象

字段

setProperties

public void setProperties(Properties properties)

指定者:

setProperties 在接口中 com.baomidou.mybatisplus.extension.plugins.inner.InnerInterceptor

buildTableExpression

public net.sf.jsqlparser.expression.Expression buildTableExpression(net.sf.jsqlparser.schema.Table table,
 net.sf.jsqlparser.expression.Expression where,
 String whereSegment)

构建租户条件表达式

指定者:

buildTableExpression 在类中 com.baomidou.mybatisplus.extension.plugins.inner.BaseMultiTableInnerInterceptor

参数:

table - 表对象

where - 当前where条件

whereSegment - 所属Mapper对象全路径（在原租户拦截器功能中，这个参数并不需要参与相关判断）

返回:
