[teiid-issues] [JBoss JIRA] (TEIID-5714) Can't push cross source function
[
https://issues.jboss.org/browse/TEIID-5714?page=com.atlassian.jira.plugin...
]
Steven Hawkins updated TEIID-5714:
----------------------------------
Workaround Description:
An ugly workaround would be to use a procedure:
begin
create local temporary table t (c bigdecimal);
loop on (SELECT TAB1.STRINGCOL, TAB1.DATE FROM MODEL2.TABLE1 TAB1) as x
begin
insert into t values (MODEL1."dbo.examplefunc"(STRINGCOL, DATE, TRUE) );
end
select * from t;
end
If there is another source table on MODEL1 another slightly less ugly workaround would be
to use a subquery associated with MODEL1:
SELECT (SELECT MODEL1."dbo.examplefunc"(TAB1.STRINGCOL, TAB1.DATE, TRUE) FROM
MODEL1.TABLEX LIMIT 1) MODEL2.TABLE1 TAB1
Can't push cross source function
--------------------------------
Key: TEIID-5714
URL: https://issues.jboss.org/browse/TEIID-5714
Project: Teiid
Issue Type: Bug
Components: Query Engine
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Priority: Major
Fix For: 12.2, 12.1.1
With two sources, MODEL1 and MODEL2, with a function on MODEL1:
CREATE FOREIGN FUNCTION "dbo.examplefunc"(col1 string, col2 date, col3 boolean)
returns bigdecimal;
A query of the function against only a table on MODEL2 will fail with "cannot be
pushed to source":
SELECT MODEL1."dbo.examplefunc"(TAB1.STRINGCOL, TAB1.DATE, TRUE) FROM
MODEL2.TABLE1 TAB1
