-----------------------------------
Summary: Informix translator - convert function in definition of view is not
pushed down
Key: TEIID-3813
URL:
https://issues.jboss.org/browse/TEIID-3813
Project: Teiid
Issue Type: Bug
Affects Versions: 8.7.1.6_2
Reporter: Juraj Duráni
Assignee: Steven Hawkins
I defined a view (see definition below). When I try to select all rows from the view,
teiid/informix jdbc driver throws an exception.
Teiid DDL:
{code:sql}
CREATE VIEW U6 (StringCol string,
IntCol integer)
AS
SELECT CONVERT(BQT1.SmallA.IntNum, string) AS StringCol, BQT1.SmallA.IntNum AS IntCol
FROM BQT1.SmallA
UNION ALL
SELECT BQT1.SmallB.StringNum, CONVERT(BQT1.SmallB.StringNum, integer)
FROM BQT1.SmallB;
}
{code}
Query:
{code:sql}
SELECT * FROM VQT.U6
{code}
Source-specific query
{code:sql}
SELECT g_1.intnum AS c_0, g_1.intnum AS c_1 FROM smalla AS g_1 UNION ALL SELECT
g_0.stringnum AS c_0, g_0.stringnum AS c_1 FROM smallb AS g_0
{code}
Actual exception:
{code:text}
Caused by: java.sql.SQLException: The statement failed because corresponding column data
types must be compatible for each UNION, INTERSECT, or MINUS query.
