QSM-01049: semi-join check failed for materialized view, string

QSM-01049: semi-join check failed for materialized view, string
Cause: If there is a semi join in the query, then Query Rewrite will create (select distinct , from mjv) where is the list of rowids/pk of all mjv tables that don't correspond to a right side of a semi-join and are their columns. Query Rewrite will not occur if a join from the materialized view cannot match the semi-join from the query.
Action: None

QSM-01049:实体化视图,字符串的半连接检查失败,
.原因:如果查询中有半连接,则Query Rewrite将创建(从mjv中选择distinct ),其中是所有mjv的rowids / pk的列表与半连接的右侧不对应的表和是它们的列。如果来自物化视图的连接与查询中的半连接不匹配,则不会发生查询重写。,
.行动:无,
