<p>Does anybody know if there is a way to make autocompletion work in MySQL Command Line Client under Windows? It's working nicely under Linux for me, but  simply moves the cursor under Windows instead.</p>

It ought to work this way:
```
```
C:\> mysql --auto-rehash
```
```
Or configure your my.cnf:
```
```
[mysql]
auto-rehash
```
```
edit:
My apologies.  I have found some references that the tab-completion feature in mysql client works only on UNIX/Linux.  It does not work on Windows.
update:
The reason for this is mentioned briefly in MySQL
bug #4731

I just downloaded 4.0.15 - command
  completion in mysql.exe is NOT
  working, as expected. It was never
  working in mysql.exe because we were
  not able to make readline to compile
  with VC++.
mysqlc.exe is a cygwin build, and it is linked with readline.
Explanation:
GNU readline
is a standard open-source library for handling user input.  The MySQL team uses the readline library, but they are not its author.  From the above comment, I understand that they were unsuccessful in compiling the readline library on Windows with Microsoft Visual C++, the tool they use to build the MySQL product.  Some open-source projects have not been made fully compatible with the Microsoft Windows environment.
At one time in the past, the MySQL product provided an alternative client they called
```
mysqlc.exe
```
, which they compiled with the
cygwin
toolset on Windows, but they don't provide this anymore.  The cygwin toolset includes the readline library, so it was possible to compile the
```
mysqlc.exe
```
client with support for tab-completion.
So in theory, if you are really intrepid, you could download the cygwin toolset including the readline library, then download the MySQL source code and build it using cygwin.  Then you should have a mysql client program that can perform tab-completion.  But this sounds like a lot of work even for someone who is familiar with building MySQL from source.
