the error I get with that is:
SQL> create or replace package tpccrand is 2 --
3 type Tperm is varray (3000) of integer; 4 randperm3000 Tperm; 5 -- 6 type Tlastname is varying array (10) of varchar2(10); 7 lastname Tlastname := 8 T_lastname( 'BAR', 'OUGHT', 'ABLE', 'PRI', 9 'PRES', 'ESE', 'ANTI', 'CALLY', 10 'ATION', 'EING' 11 ); 12 -- 13 procedure initperm; 14 procedure randstr (str out varchar2, x in integer, y in integer); 15 procedure randdatastr (str out varchar2, x in integer, y in 16 integer); 17 procedure randnum (str out varchar2, len in integer); 18 procedure randlastname (str out varchar2, id in integer); 19 function NURand (A in integer, x in integer, y in integer, 20 cnum in integer) return integer;21 end tpccrand;

Errors for PACKAGE TPCCRAND:
LINE/COL ERROR
-------- ----------------------------------------------------------------- 7/18 PL/SQL: Declaration ignored 8/7 PLS-00201: identifier 'T_LASTNAME' must be declared
That looks like a typo -- you have T_lastname not tLastName. Once you fix that however, you'll get:
1 create or replace package tpccrand is 2 --
3 type Tperm is varray (3000) of integer; 4 randperm3000 Tperm; 5 -- 6 type TlastName is varying array (10) of varchar2(10); 7 lastname TlastName := 8 TlastName( 'BAR', 'OUGHT', 'ABLE', 'PRI', 9 'PRES', 'ESE', 'ANTI', 'CALLY', 10 'ATION', 'EING' 11 ); 12 -- 13 procedure initperm; 14 procedure randstr (str out varchar2, x in integer, y in integer); 15 procedure randdatastr (str out varchar2, x in integer, y in integer); 16 procedure randnum (str out varchar2, len in integer); 17 procedure randlastname (str out varchar2, id in integer); 18 function NURand (A in integer, x in integer, y in integer, 19 cnum in integer) return integer;20* end tpccrand;
LINE/COL ERROR
-------- -----------------------------------------------------------------
7/18 PLS-00492: variable or constant initialization may not refer to
functions declared in the same package
7/18 PL/SQL: Declaration ignored
meaning you cannot initialize lastname in the spec. We must do that in the body. So, we will record the spec as:
1 create or replace package tpccrand is 2 --
3 type Tperm is varray (3000) of integer; 4 randperm3000 Tperm; 5 -- 6 type TlastName is varying array (10) of varchar2(10); 7 lastname TlastName; 8 /* 9 lastname TlastName := 10 TlastName( 'BAR', 'OUGHT', 'ABLE', 'PRI', 11 'PRES', 'ESE', 'ANTI', 'CALLY', 12 'ATION', 'EING' 13 ); 14 */ 15 -- 16 procedure initperm; 17 procedure randstr (str in out varchar2, x in integer, y in integer); 18 procedure randdatastr (str in out varchar2, x in integer, y in integer); 19 procedure randnum (str in out varchar2, len in integer); 20 procedure randlastname (str in out varchar2, id in out integer); 21 function NURand (A in integer, x in integer, y in integer, 22 cnum in integer) return integer;23* end tpccrand;
I remove the initialization. ALSO i change str and id to be IN OUT (since you do READ and WRITE to them in the body below)
We put in the body code like:
SQL> create or replace package body tpccrand is
2 procedure initperm is 3 pos binary_integer; 4 temp integer; 5 i binary_integer; 6 begin 7 for i in 0..2999 loop 8 randperm3000(i) := i+1; 9 end loop; 10 10 for i in reverse 3000..1 loop 11 pos := mod(random.val(0,3000),i); 12 temp := randperm3000(i-1); 13 randperm3000(i-1) := randperm3000(pos); 14 randperm3000(pos) := temp; 15 end loop; 16 end initperm; 17 17 procedure randstr (str in out varchar2, x in integer, y in integer) is 18 i binary_integer; 19 j binary_integer; 20 len binary_integer; 21 begin 22 len := random.val(x,y+1); 23 str := ''; 24 for i in 0..len-1 loop 25 j := random.val(0,62); 26 if j < 26 then 27 str := str || chr(j + 97); 28 elsif j < 52 then 29 str := str || chr(j + 65 - 26); 30 else 31 str := str || chr(j + 48 - 52); 32 end if; 33 end loop; 34 end randstr; 35 35 procedure randdatastr (str in out varchar2, x in integer, y ininteger)
37 i binary_integer; 38 j binary_integer; 39 len binary_integer; 40 pos binary_integer; 41 begin 42 len := random.val(x,y+1); 43 str := ''; 44 for i in 0..len-1 loop 45 j := random.val(0,62); 46 if j < 26 then 47 str := str || chr(j + 97); 48 elsif j < 52 then 49 str := str || chr(j + 65 - 26); 50 else 51 str := str || chr(j + 48 - 52); 52 end if; 53 end loop; 54 if ( random.val(0,10) = 0 ) then 55 pos := random.val(1,len-8); 56 str := substr(str,1,pos-1) || 'ORIGINAL' || substr(str,pos+8); 57 end if; 58 end randdatastr; 59 59 procedure randnum(str in out varchar2,len in integer) is 60 i binary_integer; 61 begin 62 str := ''; 63 for i in 1..len loop 64 str := str || chr(48 + random.val(0,10)); 65 end loop; 66 end randnum; 67 67 procedure randlastname (str in out varchar2,id in out integer) is 68 begin 69 id := mod(id,1000); 70 str := lastname(id/10); 71 str := str || lastname( mod(id/10,10) ); 72 str := str || lastname( mod(id,10) ); 73 end randlastname; 74 74 function NURand (A in integer, x in integer, y in integer, 75 cnum in integer) return integer is 76 ta binary_integer; 77 tb binary_integer; 78 begin 79 ta := random.val(0,A+1); 80 tb := random.val(x,y+1); 81 end NURand;
83 lastName := 84 TlastName( 'BAR', 'OUGHT', 'ABLE', 'PRI', 85 'PRES', 'ESE', 'ANTI', 'CALLY', 86 'ATION', 'EING' 87 );
Package body created.
See, we put at the bottom some elaboration code to initialize lastname (instead in the spec). Also -- I removed the duplicate randlastname and nurand functions you had as well.
So, this now *compiles* but I don't know if it *works* :)
