I installed the GoMySQL using goinstall
goinstall github.com/Philio/GoMySQL
And cloned a version from github, the diff on statement.go shows on
612c612
< err = s.c.command(COM_STMT_RESET, s.statementId)
---
> err = s.c.command(COM_STMT_CLOSE, s.statementId)
Which exactly what thomas has commited for the latest version.
