Sending passwords in clear text may be a security problem in some configurations.

```

||||
* `<enum_var>=<value>`: `SET <enum_var>=<value>`
|
||||
* `<string_var>=%27<value>%27`: `SET <string_var>='<value>'`
|
||||
|
||||
Rules:
|
||||
* The values for string variables must be quoted with '
|
||||
* The values must also be [url.QueryEscape](http://golang.org/pkg/net/url/#QueryEscape)'ed!
|
||||
(which implies values of string variables must be wrapped with `%27`)

||||
Examples:
|
||||
* `autocommit=1`: `SET autocommit=1`
|
||||
* [`time_zone=%27Europe%2FParis%27`](https://dev.mysql.com/doc/refman/5.5/en/time-zone-support.html): `SET time_zone='Europe/Paris'`

* [`tx_isolation=%27REPEATABLE-READ%27`](https://dev.mysql.com/doc/refman/5.5/en/server-system-variables.html#sysvar_tx_isolation): `SET tx_isolation='REPEATABLE-READ'`
