Converting OLE Object in Sql Server to Oracle

Question

SQL Server contains datatype OLE Object. This is basically an array of binary floating point data where each value of the array is 4 byte long. How can I store these values in Oracle database.
null

Answer 1

You cannot specify the precision/scale or length of input paramters to a stored procedure in Oracle, or at least the pl/sql engine does not respect the sizing. Assuming that you want to do something with variable1 in the procedure, and not just return it, the Oracle equivalent would be something along the lines of:
SQL> CREATE FUNCTION f (p_param1 IN VARCHAR2,
  2                     p_param2 IN NUMBER,
  3                     p_param3 IN NUMBER) RETURN NUMBER IS
  4     l_var1 NUMBER(20) := SUBSTR(p_param1, p_param2, p_param3);
  5  BEGIN
  6     RETURN l_var1 * 10;
  7  END;
  8  /
Function created.
SQL> SELECT f('ABC10DEF', 4, 2) FROM dual;
F('ABC10DEF',4,2)
              100You may need to adjust the return type to match what you are actually returning.
You can also use this iin a direct assignment in pl/sql without doig a select, something like:
SQL> DECLARE
  2     l_num NUMBER(20);
  3  BEGIN
  4     l_num := f('ABC10DEF', 4, 2);
  5     DBMS_OUTPUT.Put_Line('The number is: '||l_num);
  6  END;
  7  /
The number is: 100John
