我正在使用最新的 Saiku 3.8.3 独立版本,并且在使用具有不同架构的数据库 PostgreSQL 9.1 和 PUBLIC 时遇到了一些问题。
我创建了数据源并正确连接,这是我使用的数据源,没有个人详细信息:
type=OLAP
name=chegadaturistas
driver=mondrian.olap4j.MondrianOlap4jDriver
location=jdbc:mondrian:Jdbc=jdbc:postgresql://DBNAME:PORT/DB;Catalog=mondrian:///datasources/chegada_turistas.xml;JdbcDrivers=org.postgresql.Driver;
username=postgres
password=PASSWORD
security.enabled=false
我还使用旧选项创建了 Mondrian Schema,因为我使用了 Schema Workbench。这是我创建的架构:

问题是,当我运行 Saiku 时,我看不到架构,并且它在日志中有这个错误:
2016-04-08 08:17:31,976 WARN [mondrian.rolap.RolapSchema] Model is in legacy format
2016-04-08 08:17:36,725 ERROR [org.saiku.web.core.SecurityAwareConnectionManager] Error connecting: chegadaturistas
mondrian.olap.MondrianException: Mondrian Error:Internal error: Reading row count from table [null, null, tempo]; sql=[select count(*) from "tempo"]
所以我注意到 mondrian 在 COUNT 中使用的选择只是表,而不是应该在 PostgreSQL 上使用的 schema.table。为了确保我在 PostgreSQL 公共模式中创建了一个 VIEW,它并没有在“tempo”表中给我这个错误,而是给了我另一个错误。有没有办法强制 Mondrian 在选择 PosgreSQL 时使用 SCHEMA.TABLE?
