Question

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.

Answer 1

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.
