mySQL and primary key

[Ralph DiMola]

JBV,

This looks like a server timeout. There is a mySQL server ini file parameter
"ExecTimeLimit" There is also a phpMyAdmin ini file "LoginCookieValidity"
timeout parameter. If you can't get those changed(especially "ExecTimeLimit"
so you can do it by script) you will be forced to create a new table with a
primary key and copy the data over in chunks small enough to avoid a
timeout.

Subject: mySQL and primary key

Hi list,

I have a mySQL table with 13500000 entries that weights almost 20 Gb.
I need to create a primary key on the "id" column.
I have tried in phpMyAdmin as well as in a script with "ALTER TABLE myTable
ADD PRIMARY KEY(id)", but each time I get a "504 Gateway Timeout" error, and
no index is created.

What else can I try ?

Thank you in advance.
jbv
