which mysql was being used

I uninstalled wamp on localhost windows 7

I am not sure what mysql I was running because I previously had
php/apache/mysql (php zend framework)

now I open mysql workbench and I see no databases, says not connected

How can I run mysql again

A related question is the answer if it is wamp

but what if it is not wamp mysql, maybe it is xampp mysql or php apache mysql

You don't do queries. Just copy/paste with replace.

If you do not copy the data folder, MySQL does not have access to  your old data, so you cannot do selects.
Dan CraciunIT ConsultantCommented:
On XAMPP you run xampp-control.exe, then on the control panel you can see if MySQL is running and on what port (and if you press on "Admin" you're taken to phpmyadmin's login page).

If you installed mysql as a standalone install, it will be under Program Files/Mysql or similar (don't know if that's changed since Oracle bought MySQL). Check for a "Data" folder there. If it's there and not empty, then you still have your data.

You could check your mysql installation directory in your system like C:/mysql or D:/mysql   ... then you can start the service and connect through workbench..

C:/mysql or D:/mysql
no d drive
no c/mysql

On XAMPP you run xampp-control.exe,
xammp is uninstalled no exe file

Program Files/Mysql
no c/programfiles/mysql
no no c/programfilesx86/mysql
Do a global search for ibdata1 (the MySQL database)

In the WAMP folder search for my.ini and check the data path is pointing to the data folder (the newer one) - probably don't need to do this
In the WAMP folder look for mysqld.exe and double click file
If that starts up OK then check Workbench again.

(but that ibdata1 file looks very small)

# Don't listen on a TCP/IP port at all. This can be a security enhancement,

# Replication Slave (comment out master section to use this)
# To configure this host as a replication slave, you can choose between
# two methods :
# 1) Use the CHANGE MASTER TO command (fully described in our manual) -
#    the syntax is:
#    MASTER_USER=<user>, MASTER_PASSWORD=<password> ;
#    where you replace <host>, <user>, <password> by quoted strings and
#    <port> by the master's port number (3306 by default).
#    Example:
#    MASTER_USER='joe', MASTER_PASSWORD='secret';
# OR
# 2) Set the variables below. However, in case you choose this method, then
#    start replication for the first time (even unsuccessfully, for example
#    if you mistyped the password in master-password and the slave fails to
#    connect), the slave will create a master.info file, and any later
#    change in this file to the variables' values below will be ignored and
#    overridden by the content of the master.info file, unless you shutdown
#    the slave server, delete master.info and restart the slaver server.
#    For that reason, you may want to leave the lines below untouched
#    (commented) and instead use CHANGE MASTER TO (see above)

#master-host     =   <hostname>
# The username the slave will use for authentication when connecting
# to the master - required
#master-user     =   <username>
# The password the slave will authenticate with when connecting to
# the master - required
#master-password =   <password>
# The port the master is listening on.
# optional - defaults to 3306
#master-port     =  <port>

Open in new window

I can not find mysqld.exe
but  in

I saw folders named as my old database names

so I think wamp is the correct mysql
Dan CraciunConnect With a Mentor IT ConsultantCommented:

So backup the \data folder in another location (just in case), reinstall wamp and all should work. If not, copy the \data folder back into the new mysql install location.

GaryConnect With a Mentor Commented:
If there is nothing under

then you have no MySQL Server installed.
rgb192Author Commented:
there is one mysqld.exe

am I forced to install old wamp (I am not sure of which wamp I was using)

I have exe of new wamp (I think has a different version of mysql)
rgb192Author Commented:
Ok, that was a difficult question about changing mysql and still having mysql access.  Easier question is: is all the information in the data folder.

For example can I try the new wamp and realize that mysql does not start with the mysql backup and then install the old wamp.

Are there other hidden files in addition to data folder that relate to the starting of mysql
Dan CraciunIT ConsultantCommented:
The data folder contains only the data. The rest of the config files are in different folders.

You can backup the data folder, delete the mysql folder, install wamp/xampp, make sure mysql starts ok and then restore the data folder, overwriting the files already there.

This will preserve your data into the new, working, mysql install.

rgb192Author Commented:
so is data

the table data for my 3 databases

select *
and fields
rgb192Author Commented:
basedir and data folder

Later I learned how to do a restore based on this information.
