Build Identifier:

this CASTing worked on previous versions of MonetDB, it does not work on SP-2 windows. Hannes tested on SP-1 and said it did not fail there.

it is now preventing the PISA script from working

https://github.com/ajdamico/usgsd/tree/master/Program%20for%20International%20Student%20Assessment

Reproducible: Always

Steps to Reproduce:

create table test (a varchar(100) ) ;
INSERT INTO test (a) VALUES ('0.10');
INSERT INTO test (a) VALUES ('9999.00') ;
UPDATE test SET a = NULL WHERE a IN ( 9999 ) ;

Actual Results:

Welcome to mclient, the MonetDB/SQL interactive terminal (Jan2014-SP2)
Database: MonetDB v11.17.17 (Jan2014-SP2), 'demo'
Type \q to quit, ? for a list of available commands
auto commit mode: on
sql>
sql>create table test (a varchar(100) ) ;
operation successful (222.637ms)
sql>INSERT INTO test (a) VALUES ('0.10');
1 affected row (35.888ms)
sql>INSERT INTO test (a) VALUES ('9999.00') ;
1 affected row (14.665ms)
sql>UPDATE test SET a = NULL WHERE a IN ( 9999 ) ;
conversion of string '0.10' to type sht failed.

It did work with SP1, even if it probably should not have. Regardless, something that did not complain before now does. Breaks things...

the string 9999.00 != 9999, ie what is the expected result. I agree the error message is incorrect.
