Pass array as input parameter to an oracle stored procedure using simple jdbc call

Question

Here is my oracle procedure specifications

CREATE OR REPLACE PACKAGE PKG_RE_FI AS

  PROCEDURE PRC_RE_FI_DETAILS(P_FAN_NO       IN VARCHAR2,
                              P_REF_ID       IN TY_APP_REF_ID,
                              P_COMMENTS     IN VARCHAR2,
                              P_BILLING_FLAG IN VARCHAR2,
                              P_STATUS       OUT VARCHAR2);
END PKG_RE_FI;

TY_APP_REF_ID is

CREATE OR REPLACE TYPE ty_app_REF_ID as varray(500) of obj_array_ref_id

CREATE OR REPLACE TYPE obj_array_ref_id  AS OBJECT(
app_ref_id VARCHAR2(100)
)

I am using Spring JDBC Framework(SimpleJdbcCall object) to execute above procedure. Below is the code snippet in which i have declared

      this.reFIJdbcCall =  new SimpleJdbcCall(dataSource).withCatalogName("PKG_RE_FI").
              withProcedureName("PRC_RE_FI_DETAILS").declareParameters(new SqlParameter("P_FAN_NO", Types.VARCHAR),
                        new SqlParameter("P_REF_ID", Types.ARRAY),
                        new SqlParameter("P_COMMENTS", Types.VARCHAR),
                        new SqlParameter("P_BILLING_FLAG", Types.VARCHAR),
                        new SqlOutParameter("P_STATUS", Types.VARCHAR)
              );

How should i pass array to the

new SqlParameter("P_REF_ID", Types.ARRAY),

to MapSqlParameterSource

 MapSqlParameterSource in = new MapSqlParameterSource();

PeudoCode for the same how I achieved.

    # 1.You will require a structDescriptor object for an object equivalent in pl sql like :

    StructDescriptor structDes= new StructDescriptor("<schemaname in caps>.<sql_object_name>", connectionObject);

    # 2. You will need to pass one object values such name, class, id to an object array in order and accordance to 'sql_object_name' object. 

    For exmaple:
    STRUCT[] structArray=new STRUCT[<ListObj>.size()];
    int index=0;
    for (a in ListObj){

    Object[] object=new Object[]{a.getName(),a.getId()};
    STRUCT struct=new STRUCT(structDes ,connectionObject,object);
               structArray[index]=struct;
               index++;

    }

    ArrayDescriptor arrayDes=ArrayDescriptor.createDescriptor(
        "<Schema name>.<table object from sql>", connectionObject);

    ARRAY array=new ARRAY(arrayDes,connectionObject, structArray);

   then pass it to proc 

   .declareParameters(
   new SqlInOutParameter("<parameter to proc name>",OracleTypes.ARRAY,"
   <schema name>.<sql_array_or_table_obj>"))

   like 
   Hashmap<String, Object> map= new HashMap<>();
   map.put("<parameter to proc name>",array);
   psStatement.execute(map);

Hope it helps. This sequence may vary as per requirement and type of sql database used, but base is same.

Answer 2

The Spring Data JDBC Extensions project has some support that makes this easier. Take a look at the reference manual for passing in an Oracle ARRAY type.

Hi.. In my case there are few more input parameters along with the array mentioned. How will the same be Done ? – Zeigler
