JPA SQL Server No Dialect mapping for JDBC type: -9

Question

Iam writing a native query like

Query query = 
  entityManagerUtil.getEntityManager().createNativeQuery(\"SELECT c.NodeID,c.Code,c.Name FROM COM_Location c\"         


        

Answer 1

I had a similar issue, my sql is this

Query nmspQuery = em.createNativeQuery("select aster from MyTable where my_column = 1001")

The datatype for PRODUCT_NODE_ONIX_TYPE in the Oracle 11g is nvarachar2

I fixed it by casting the value astr to to_char. This worked fine

Query nmspQuery = em.createNativeQuery("select TO_CHAR(aster) from MyTable where my_column = 1001")
