<div>Okay I don't have a foodmart repro path
Luc but I do know whats causing it.<br>
<br>
My client has written a schema which has a User dimension,<br>
<br>
within that dimension it has a bunch of attributes that reference
more than one table one of them is:<br>
<br>
<Attribute name="Path ID" keyColumn="PATH_ID" table="LKP_PATH"
hasHierarchy='false'/><br>
<Attribute name="Path Configuration"
keyColumn="CONFIGURATION" table="LKP_PATH"
hasHierarchy='false'/><br>
<br>
and then they include those attributes in a Hierarchy:<br>
<br>
<Hierarchy name='Path' allMemberName='All Path'><br>
<Level attribute='Path ID' /><br>
<Level attribute='Path Configuration'/><br>
</Hierarchy> <br>
<br>
This is all parsed fine by Mondrian and the schema loads.<br>
<br>
<br>
But as soon as you enable that Hierarchy and then use the Path ID
field elsewhere in the schema, in their case they also have a
dimension called Path which also uses the LKP_PATH table, thats
when the SQL gets aliased incorrectly.<br>
<br>
Luc I can send you their schema and SQL table structure offline if
that would help.<span class="HOEnZb"><font color="#888888"><br>

<div>Hi Luc, the SQL itself I'd stripped out, <br>
<br>
All I'm doing it putting a Level.Member on Rows and a
Measure on the columns.<br>
<br>
And I get: <br>

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.<br>
<br>
mysql Ver 14.14 Distrib 5.5.31, for Linux (x86_64)

I was actually trying to debug another issue for a
client, but I can't even run this query.<br>

<br>
I'm trying to get a schema running under
Mondrian 4 and Mysql and when a<br>
query is run its generating SQL like this:<br>
<br>
select `LKP_PATH`.`PATH_ID` as `c0` from
`LKP_PATH` as `LKP_PATH_1`;<br>
<br>
which MySQL is getting upset over because the
table name at the start of<br>
the select isn't the aliased table name but
the original:<br>
<br>
select `LKP_PATH_1`.`PATH_ID` as `c0` from
`LKP_PATH` as `LKP_PATH_1`;<br>
<br>
The above is a valid query.<br>
<br>
Any property I can set to get this working?<br>
<br>
Thanks<br>
