Closing active connections using RMySQL

Question

As per my question earlier today, I suspect I have an issue with unclosed connections that is blocking data from being injected into my MySQL database. Data is being allowed

Answer 1

a. dbListConnections( dbDriver( drv = "MySQL"))

b. dbDisconnect( dbListConnections( dbDriver( drv = "MySQL"))[[index of MySQLConnection you want to close]]). To close all: lapply( dbListConnections( dbDriver( drv = "MySQL")), dbDisconnect)

Yes, you could just rewrite the table, of course you would lose all data. Or you can specify dbWriteTable(, ..., overwrite = TRUE).

I would also play with the other options, like row.names, header, field.types, quote, sep, eol. I've had a lot of weird behavior in RMySQL as well. I can't remember specifics, but it seems like I've had no error message when I had done something wrong, like forget to set row.names. HTH
