Junk data appearing after literals
Posted: Fri 16 Oct 2020 13:53
Hello,
I am using the latest version of ODAC. This problem did not occur with version 10.4, but I don't know exactly when it started.
Compiling in either 32 or 64 bit VCL, RAD Studio 10.1 Berlin.
I have reproduced this with multiple Oracle versions (12.2 and 19.0) and with multiple database character sets (EE8ISO8859P2 and UTF8)
Just run these SQLs, in order, in a TSmartQuery connected to a TDBGrid.
The problem is that I get some junk characters after the literals in the first two columns.
For example, in the first column, I get : 1í
and in the second column, I get TEST (edit: there was some junk data after this too but I guess the forum removed it)
The junk data changes if I re-execute the SELECT. And it only seems to happen if I select literals. When I select CHAR values from a table, the problem does not occur.
Thanks.

Code: Select all
alter session set "_adjust_literal_replacement"=FALSE;
alter session set cursor_sharing = 'FORCE';
SELECT '1' AS col1,
'TEST' AS col2,
cast ('1' AS CHAR (8)) AS col1_aschar,
cast ('TEST' AS CHAR (8)) AS col2_aschar
FROM dual;
