Question

I have a problem with a pl/sql anonymous block. Although I can show the variables that get with select query, I get a casting error if I use it in update sentence.

My code looks like this:

set serveroutput on

DECLARE

var1 scheme.table.column1%type; /* number[8,0] */
var2 scheme.table.column2%type; /* number[8,2] */

BEGIN

/* return simple value */
select t.column1, t.column2
into var1, var2
from scheme.table t
where <condition>

DBMS_OUTPUT.PUT_LINE('Var1 is: ' || var1 || ' Var2 is:' || var2); /* fine!!*/

update scheme.table
set scheme.table.column1 = var1 + 1
where scheme.table.column2 = var2; /* that is line error*/

END;

/*
ORA-06502: PL/SQL: error : error de conversión de carácter a número numérico o de valor
ORA-06512: en línea 58
06502. 00000 -  "PL/SQL: numeric or value error%s"
*/

Can somenone help me?
