Hello Everyone,
I just installed the NPetshop and (without too much effort) making It
fully working with SQL Server. However, when I switch database to
Oracle, It becomes harder. I have Oracle9i database server running on
NT.
And have tried ODP.NET 9.2 and ODP.NET 10.4 got the same result.
The problem is on the Mapper:
<select id="GetProductListByCategory"
cacheModel="ProductList-cache" resultMap="ProductList"
parameterClass="string">
select
Product_Id,
Product_Name,
Product_Description,
P.Category_Id,
Category_Name,
Category_Description
from Products P, Categories C
where C.Category_ID= P.Category_ID and
P.Category_Id = #value#
</select>
The server log shows Ibatis send the following statement:
select
Product_Id,
Product_Name,
Product_Description,
P.Category_Id,
Category_Name,
Category_Description
from Products P, Categories C
where C.Category_ID= P.Category_ID and
P.Category_Id = :value
Which always return an empty dataset. I wonder Ibatis should directly
replace
#value# to the constant (like 'FISH') or sedning the value as a
parameter to :value?
Please help me out.
Thanks,
Follow is the provider.config section for the test.
