Hi Luc, the SQL itself I'd stripped out,
All I'm doing it putting a Level.Member on Rows and a Measure on the
columns.
And I get:
Caused by: mondrian.olap.MondrianException: Mondrian Error:Failed to
load segment form SQL
at
mondrian.rolap.agg.SegmentLoader.createExecuteSql(SegmentLoader.java:643)
at
mondrian.rolap.agg.SegmentLoader.loadImpl(SegmentLoader.java:195)
... 8 more
Caused by: mondrian.olap.MondrianException: Mondrian Error:Internal
error: Error while loading segment; sql=[select `LKP_PATH`.`PATH_ID` as
`c0`, count(`FCT_RESUMEUPLOAD`.`FACT_RESUMEUPLOAD_KEY`) as `m0` from
`LKP_PATH` as `LKP_PATH_1`, `FCT_RESUMEUPLOAD` as `FCT_RESUMEUPLOAD`
where `FCT_RESUMEUPLOAD`.`PATH_KEY` = `LKP_PATH`.`PATH_KEY` and
`LKP_PATH`.`PATH_ID` = 'hello' group by `LKP_PATH`.`PATH_ID`]
Thats the real SQL generated. I'm using the latest Mondrian 4 + Saiku
build from our CI, its tagged 4.0.0-SNAPSHOT so I don't know what exact
Mondrian 4 build it used but it was built 11 hours ago.
mysql Ver 14.14 Distrib 5.5.31, for Linux (x86_64) using readline 5.1
I was actually trying to debug another issue for a client, but I can't
even run this query.
Cheers
Tom
