How to deal with a char column in select statement
Hi,
I have to query on tables which have CHAR columns (length 5 for example)
as ID.
Let's say we have some lines with these ID values : XXXXX, YYYYY, ZZZ
[2 white spaces at the end]. As u can see there is no restriction about
the length of the value : it can less than five characters.
Here is my select statement in a sql map config file :
<select id="select1" parameterClass="string" parameterMap="result-map" >
Select id, lib1, lib2 from myTable where id = #value#
</select>
Here is the problem : if I use the value "ZZZ" as parameter value then
the statement finds no result. I must pass "ZZZ " value to make the
query ok
My connection (an oracle connection actually) has the
"fixed[Default]String" property set to true, provided by an initial
properties file.
The strange thing is : the query (with this "ZZZ" value) works fine
with a spring class like JdbcTemplate
Any help is greatly appreciated
Regards,

Just curious: What is the added value of using CHAR instead of VARCHAR
in this case?
