Accessing the Custom Object Return type from oracle pl/sql in java

Question

I have created a procedure which signature is as follows :

PROCEDURE CUSTOMER_LIST_FOR_SUSPICIOUS_CHECK (
      pCustNo             NUMBER,
      pCustomerList   OUT EMOB.PKG_FINGER.CUSTOMER_LIST,
      pErrorFlag      OUT VARCHAR2,
      pErrorMessage   OUT VARCHAR2);

So I want to call this procedure from java . I have researched a lot and got the following code :

String query = "begin BIOTPL.PKG_FINGER.CUSTOMER_LIST_FOR_SUSPICIOUS_CHECK(?, ?, ?, ?); end;";
CallableStatement stmt = conn.prepareCall(query);

stmt.setInt(1, 83);
stmt.registerOutParameter(2, OracleTypes.ARRAY, "BIOTPL.PKG_FINGER.CUSTOMER_LIST");
stmt.registerOutParameter(3, OracleTypes.VARCHAR);
stmt.registerOutParameter(4, OracleTypes.VARCHAR);
stmt.execute();

But After executing the above code I am getting the following error :

The definition of customer_list is given by as follows :

TYPE CUSTOMER_REC IS RECORD
   (
      CUST_NO     NUMBER,
      CUST_CODE   VARCHAR2 (50),
      CUST_NAME   VARCHAR2 (500)
   );

   TYPE CUSTOMER_LIST IS TABLE OF CUSTOMER_REC
      INDEX BY BINARY_INTEGER;

I cant understand where is the error ? Please help me to resolve the error and get the parameter from oracle pl/sql procedure .

Answer 1

The Oracle driver has a special API for this usecase called registerIndexTableOutParameter . Your code would look like this:

((oracle.jdbc.OracleCallableStatement)stmt).registerIndexTableOutParameter(2, 500, OracleTypes.STRUCT, 0);

See the JavaDoc for more details about what the parameters are: https://docs.oracle.com/database/121/JAJDB/oracle/jdbc/OracleCallableStatement.html#registerIndexTableOutParameter_int__int__int__int_
