R: Check if default database is available.

mariadbHasDefault {RMariaDB} | R Documentation

## Check if default database is available.

### Description

RMariaDB examples and tests connect to a database defined by the `rs-dbi` group in `~/.my.cnf`. This function checks if that database is available, and if not, displays an informative message. `mariadbDefault()` works similarly but throws a testthat skip condition on failure, making it suitable for use in tests.

### Usage

    mariadbHasDefault()

    mariadbDefault()

### Examples

    if (mariadbHasDefault()) {
      db <- dbConnect(RMariaDB::MariaDB(), dbname = "test")
      dbListTables(db)
      dbDisconnect(db)
    }
