RE: Bind values missing from SQL trace

Rich,

I just did a quick test on 9204 where I got the following :

PARSING IN CURSOR #1 len=51 dep=0 uid=23 oct=3 lid=23 tim=1159428269085500 hv=3817972469 ad='5417974c' select * from norman where n = :nfred and v = :fred END OF STMT
PARSE
#1:c=1000,e=813,p=0,cr=0,cu=0,mis=1,r=0,dep=0,og=0,tim=1159428269085479
BINDS #1:
 bind 0: dty=1 mxl=2000(200) mal=00 scl=00 pre=00 oacflg=03 oacfl2=10 size=2000 offset=0

   bfp=40638764 bln=2000 avl=16 flg=05
   value=""
 bind 1: dty=1 mxl=128(100) mal=00 scl=00 pre=00 oacflg=03 oacfl2=0 size=128 offset=0

   bfp=4063ca70 bln=128 avl=07 flg=05
   value="varchar"
EXEC

WAIT #1: nam='SQL*Net message to client' ela= 6 p1=1650815232 p2=1 p3=0 FETCH
#1:c=0,e=122,p=0,cr=3,cu=0,mis=0,r=0,dep=0,og=4,tim=1159428269111297
*** 2007-08-16 09:56:03.320
WAIT #1: nam='SQL*Net message from client' ela= 15381631 p1=1650815232 p2=1 p3=0
STAT #1 id=1 cnt=0 pid=0 pos=1 obj=17766 op='TABLE ACCESS FULL NORMAN (cr=3 r=0 w=0 time=112 us)'

In the above, and for every test carried out, The N type bind variables are never displayed. The table is simple :

Interestingly, the trace shows both binds as having the same data type (dty=1) but with different max lengths (mxl=2000(200) for the NVVARCHAR2 and mxl=128(100) for the VARCHAR2. The AVL for the NVARCHAR is 16 bytes long, when the data was actually 8 bytes for the VARCHAR2 it is 7 bytes - which is as supplied.

So, it looks remarkably like your 'problem' is simply that N data type binds don't get listed to trace files.

My testing went as follows :

create table norman (n nvarchar2(100), v varchar2(100)); var nfred nvarchar2(1000)
var fred varchar2(100)
exec :nfred := n'nvarchar'
exec :fred := 'varchar'
select * from norman where n = :nfred and v = :fred;

HTH Cheers,
Norm.
