System package SYS.DBMS_LOB

    XMLWordPrintable

Details

    Description

      Implement a subset of the system package SYS.DBMS_LOB:

      • Procedure DBMS_LOB.APPEND - overloaded
      • Function DBMS_LOB.SUBSTR - overloaded
      • Procedure DBMS_LOB.CREATETEMPORARY - overloaded
      • Procedure DBMS_LOB.GETLENGTH - overloaded
      • Function DBMS_LOB.READ - overloaded

      Using a BLOB variable as a handle should be supported:

      CREATE TABLE t1 (a BLOB);
      		 
      INSERT INTO t1 VALUES (utl_raw.cast_to_raw('test'));
      		 
      DECLARE
      		 
        va BLOB;
      		 
        buffer RAW(1);
      		 
        len INTEGER;
      		 
        amount INTEGER:= 1;
      		 
        pos INTEGER :=1;
      		 
      BEGIN
      		 
        SELECT a INTO va FROM t1;
      		 
        len:= DBMS_LOB.getlength(va);
      		 
        WHILE pos <= len
      		 
        LOOP
      		 
          DBMS_LOB.READ(va, amount, pos, buffer);
      		 
          DBMS_OUTPUT.PUT_LINE(utl_raw.cast_to_varchar2(buffer));
      		 
          pos:= pos + 1;
      		 
        END LOOP;
      		 
      END;
