PLS-00497: cannot mix between single row and multi-row (BULK) in INTO list

Question

Hi,
I have a requirement to send a table data through mail,
so am using execute statement after opening the connection and am using the following PLSQL code, which am failing to execute successfully.
My code goes like this.
    0            10            20           30           40            50

7   PRODOAID IN NUMBER )
8   AS
9   BATCHNO  VARCHAR2(32767);
10  PCSBOX  NUMBER;
11  AMOUNT  NUMBER;
12  SMTPHOST VARCHAR2(255) := 'XXX.XXX.X.XXX' ;
13  A UTL_SMTP.CONNECTION ;

The variables BATCHNO, PCSBOX and AMOUNT are defined as scalar variables. Check there definition
> 9   BATCHNO  VARCHAR2(32767);
> 10  PCSBOX  NUMBER;
> 11  AMOUNT  NUMBER;
You cannot use BULK COLLECT on scalar variables. The variables must be defined as a COLLECTION TYPE in order to perform bulk collect.
