獲取錯誤CallableStatementCallback;錯誤的SQL語法，同時從postgreSQL調用程序

Question

我使用Spring-JDBC支持和PostgreSQL並且出現錯誤。我能夠從後端運行proc。所以它的編譯過程。

CREATE OR REPLACE PACKAGE schemaname.my_pkg_name 
IS 
PROCEDURE update_email(person_id numeric, OUT email_gratitude_id numeric); 
END my_pkg_name; 

CREATE OR REPLACE PACKAGE BODY schemaname.my_pkg_name 
IS 
PROCEDURE update_email(person_id numeric, OUT email_gratitude_id numeric) IS 

begin 
select email_gratitude_id into email_gratitude_id from schemaname.emp_email_dtls_tbl 
where person_id=person_id; 

end; 
END my_pkg_name 

private class EmployeeSP extends StoredProcedure 
{ 
    private static final String SPROC_NAME = "schemaname.my_pkg_name.update_email"; 

    public EmployeeSP(DataSource datasource) 
    { 
     super(datasource, SPROC_NAME);      
     declareParameter(new SqlParameter("person_id", Types.INTEGER));   
     declareParameter(new SqlOutParameter("email_gratitude_id", Types.INTEGER)); 

     compile(); 
    } 

    public Object execute(int emp_id) 
    { 
     Map<String,Object> results = super.execute(emp_id,null); 
     return results.get("email_gratitude_id"); 

    } 
}; 


EmployeeSP tp = new EmployeeSP(template.getDataSource()); 
tp.execute(123456);

Answer 1

試 'CREATE FUNCTION somefunc（）返回整數AS $$' 即不是 'PACKAGE' 使用 'FUNCTION'。使用可以檢查Chapter 39. PL/pgSQL - SQL Procedural Language！你

還可以檢查
