Hi,
It is that, what you think a binary is ,...is indeed a binary.
As per the manual, If a string input or function result is a binary string,
the string has no character set or collation.
so the resultant 'binary' is expected.
if u want the resultant as:
mysql select charset(concat(tt
I know about CONVERT but I wanted to check character set of 'tt' column
and this result use in CONVERT. Something like CONVERT(id USING
CHARSET(Name))
which doesn't work.
I just wonder why CONCAT(1, ',', Name) works OK even if CHARSET(1) is
binary string and CONCAT(id, ',', Name) doesn't
just wonder why CONCAT(1, ',', Name) works OK even if CHARSET(1) is

Dear MySQL fans,
I tested CONCAT() with binary strings and I got strange result.

Part of the problem was the way the server settings were allocating
memory. The concat would work until a certain size and then the
suddenly failed to insert (inserted NULL). After the memory
configuration change, in terms of concatenating (with CONCAT) in
pieces, it seems to work at least
the
Concat command?
My concern is whether this will still in someway cause me other MySQL
resource problems?
I want to be able to insert a large text or blob of over 200-400MBs.
Thanks,
John

Hi all,
When I run the following code the default value isn't being calculated using the concat
and other functions. Instead it is setting the column definition as a string:
CONCAT(TMP
How can I rework this to get a result more like
TMP-T-2
?
USE cro;
CREATE TABLE lpamform

Hi Paul,
Using the following fixed things. However, I am surprised at why it is
not working in 4.0.18 (Win32)? Previously I had 4.0.17 (Win32) and
things work perfectly. I guess you are right, it's a bug.

Hi All,
I am running MySQL in ANSI standard mode. However the following
statement is giving unexpected result. Am I missing something?
mysql select 'This is a' || ' test string';
+---+
| 'This is a' || ' test string' |
+---+
of this nice syntax, MySQL Server
doesn't support the standard SQL-99 || operator for string concatenation;
use CONCAT() instead. Because CONCAT() takes any number of arguments, it's
easy to convert use of the || operator to MySQL Server.
If you rewrite your query as follows, you should get
