Simple query with like return wrong result

Question

Hi,
I run simple query with like.
If I use parameter I get wrong results.
If I use query without parameter results are ok.
My script:
ALTER SESSION SET NLS_SORT=BINARY_CI;
ALTER SESSION SET NLS_COMP=LINGUISTIC;
-- drop table abcd;
create table abcd (col1 varchar2(10));
INSERT INTO ABCD VALUES ('122222');
insert into abcd values ('111222');
SELECT * FROM ABCD WHERE COL1 LIKE :1; -- wrong result with value 12%
COL1
122222
*111222*
select * from abcd where col1 like '12%'; -- result ok
COL1
122222
I use Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
and query run in Oracle SQL Developer 3.1.07.

Hi,
welcome to the forum.
When you put some code please enclose it between two lines starting with {noformat}{noformat}
i.e.:
{noformat}{noformat}
SELECT ...
{noformat}{noformat}
You should specify exactly how you run your code.
If I run this statement in SQL Plus:SQL> ALTER SESSION SET NLS_SORT=BINARY_CI;
Session altered.
SQL> ALTER SESSION SET NLS_COMP=LINGUISTIC;
Session altered.
SQL>
SQL> -- drop table abcd;
SQL> create table abcd (col1 varchar2(10));
Table created.
SQL>
SQL> INSERT INTO ABCD VALUES ('122222');
1 row created.
SQL> insert into abcd values ('111222');
1 row created.
SQL>
SQL> SELECT * FROM ABCD WHERE COL1 LIKE :1;
SP2-0552: Bind variable "1" not declared.

I got this error. So I wonder how you set value 12%
Please specify exactly how you run your test as we cannot reproduce your problem.
