This is a limitation of (MS) SQL:
[org.apache.ojb.broker.accesslayer.JdbcAccessImpl] ERROR: SQLException during the execution of the query (for a com.xxx.Property): The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
What does the actual SQL look like, and what does the query you are running look like?

Hi:
I want to store an *supersize* byte array into a db table.
Below I have described the issues that I have. My question:
How do I control SQL for Schema? Do I have to write my own Velocity template and add that path to db.profile.
I have made the followings changes:
DB Type : MSSQL
In db-schema.xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE database SYSTEM "http://jakarta.apache.org/turbine/dtd/database.dtd";>
<database name="@DATABASE_DEFAULT@" defaultIdMethod="none" baseClass=""
<table name="PROPERTY" >
<column name="ID" required="true" primaryKey="true" type="INTEGER" >
</column>
<column name=" PROPERTY_NAME" required="true" primaryKey="false"
type="VARBINARY" >
</column>
<column name="PROPERTY_VALUE" required="true" primaryKey="false"
type="VARBINARY" >
</column>
</table>
</database>
It creates IMAGE datatype in MSSQL Server.
In repository.xml:
<class-descriptor
class="com.xxx.Property"
table="PROPERTY"
<attribute
attribute-name="DB_NAME"
attribute-value="mydb"
</attribute>
<field-descriptor id="1"
name="dbId"
column="ID"
jdbc-type="INTEGER"
primarykey="true"
nullable="false"
indexed="true"
autoincrement="true"
locking="false"
default-fetch="false"
/>
<field-descriptor id="2"
name="propertyName"
column="PROPERTY_NAME"
jdbc-type="VARBINARY"
primarykey="false"
nullable="true"
indexed="false"
autoincrement="false"
locking="false"
default-fetch="false"
conversion="com.xxx.yyy.Converter"
/>
<field-descriptor id="3"
name="propertyValue"
column="PROPERTY_VALUE"
jdbc-type="VARBINARY"
primarykey="false"
nullable="true"
indexed="false"
autoincrement="false"
locking="false"
default-fetch="false"
conversion="com.xxx.yyy.Converter"
/>
</class-descriptor>
When I run simple queryI get the following exception: but running in MySQL is fine.
[org.apache.ojb.broker.accesslayer.JdbcAccessImpl] ERROR: SQLException during the execution of the query (for a com.xxx.Property): The text, ntext, and image data types cannot be compared or sorted, except when using IS NULL or LIKE operator.
