Question

我们在WSO2 DSS 3.0.0上的数据服务中遇到了问题。如果我直接在数据库上执行查询，我没有错误。该数据库是Sybase版本12。

DBS

<data name="DSProgram" serviceNamespace="http://myschema.org.br">
<config id="ProgramDS">
  <property name="carbon_datasource_name">ProgramDS</property>
</config>
<query id="updateProgram" useConfig="ProgramDS">
  <sql>update aca..program set name = :name, endingdate = (case when :endingdate = '' then null else :endingdate) where course = :course</sql>
  <param name="name" sqlType="STRING"/>
  <param name="endingdate" sqlType="STRING"/>
  <param name="course" sqlType="INTEGER"/>
</query>
<operation name="updateProgram">
  <call-query href="updateProgram">
     <with-param name="name" query-param="name"/>
     <with-param name="endingdate" query-param="endingdate"/>
     <with-param name="course" query-param="course"/>
  </call-query>
</operation>
</data>
