[teiid-issues] [JBoss JIRA] (TEIID-3813) Informix translator - convert function in definition of view is not pushed down

Juraj Duráni commented on TEIID-3813:
-------------------------------------
Another examples:
1. '+'/'-'/'*'/'/' operations are not allowed on boolean
values
- Query
{code:sql}
SELECT BooleanValue, (convert(BooleanValue, float)+2) AS BooleanValuePlus2,
(convert(BooleanValue, float) - 2) AS BooleanValueMinus2, (convert(BooleanValue, float)*2)
AS BooleanValueTimes2, (convert(BooleanValue, float)/2) AS BooleanValueDiv2 FROM
BQT1.SmallA WHERE IntKey >=0 AND IntKey <=5 ORDER BY BooleanValue
{code}
- Source-specific command
{code:sql}
SELECT g_0.booleanvalue AS c_0, (g_0.booleanvalue + 2.0) AS c_1, (g_0.booleanvalue - 2.0)
AS c_2, (g_0.booleanvalue * 2.0) AS c_3, (g_0.booleanvalue / 2.0) AS c_4 FROM smalla AS
g_0 WHERE g_0.intkey >= 0 AND g_0.intkey <= 5 ORDER BY c_0
{code}
However, infromix doe not support conversion from boolean to numeric type. But in my
opinion it would be better to get exception concerning casting rather than "Routine
(equal/plus/minut/...) can not be resolved."
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.
