## dbExists test with schema name: reported as Issue 3 at
## http://code.google.com/p/rpostgresql/issues/detail?id=3
## and based on an earlier email by Prasenjit Kapat
##
## Assumes that
## a) PostgreSQL is running, and
## b) the current user can connect
## both of which are not viable for release but suitable while we test
##
## Dirk Eddelbuettel, 10 Sep 2009
## only run this if this env.var is set correctly
if (Sys.getenv("POSTGRES_USER") != "" & Sys.getenv("POSTGRES_HOST") != "" & Sys.getenv("POSTGRES_DATABASE") != "") {
## try to load our module and abort if this fails
stopifnot(require(RPostgreSQL))
stopifnot(require(datasets))
## load the PostgresSQL driver
drv <- dbDriver("PostgreSQL")
## connect to the default db
con <- dbConnect(drv,
user=Sys.getenv("POSTGRES_USER"),
password=Sys.getenv("POSTGRES_PASSWD"),
host=Sys.getenv("POSTGRES_HOST"),
dbname=Sys.getenv("POSTGRES_DATABASE"),
port=ifelse((p<-Sys.getenv("POSTGRES_PORT"))!="", p, 5432))
if (dbExistsTable(con, "rock'data")) {
cat("Removing rock'data\n")
dbRemoveTable(con, "rock'data")
}
cat("Write rock'data\n")
dbWriteTable(con, "rock'data", rock)
## run a simple dbExists
cat("Does rock'data exist? ")
print(res <- dbExistsTable(con, "rock'data"))
## this should return TRUE but did not -- does now after patch
cat("Does \"public.rock'data\" exist? ")
print(res <- dbExistsTable(con, "public.rock'data"))
## cleanup
if (dbExistsTable(con, "rock'data")) {
cat("Removing rock'data\n")
dbRemoveTable(con, "rock'data")
}
## and disconnect
dbDisconnect(con)
