mysql - writeOGR 层创建失败 - MySQL

Question

我正在尝试将多边形边界加载到 mysql。到目前为止，这是我尝试过的，

1. 用 mysql 驱动程序安装了 gdal。在 R 中使用 ogrDrivers() 检查，它在驱动程序列表中返回 MySQL。

   db <- 'testdb'
   user <- 'testuser'
   pwd <- '****'
   host <- '127.0.0.1'
   
   DSN = paste0('MySQL:',db ,',user=', user, ',host=', host, ',password=', pwd)
   
   data_2013 <- readOGR(dsn = "/Path/to/shapefile", layer = "testinglayer")
   
   writeOGR(data_2013, dsn=DSN, driver='MySQL',layer='testinglayer', layer_options='ENGINE=Aria', overwrite_layer = TRUE)
   

但是我得到了这个错误，

Error in writeOGR(data_2013, dsn = DSN, driver = "MySQL", layer = "testinglayer",  : 
  Layer creation failed

或者有没有其他方法可以将空间多边形数据从 R 加载到 MySQL？

Answer 1

看着这个link , 参数必须以逗号分隔。所以也许这会起作用:

DSN = paste0('MYSQL:dbname=',db ,', user=', user, ', host=', host, ', password=', pwd, ', port=', port)

或者您是否尝试过 sf包？

DSN = paste0('MYSQL:dbname=',db ,' user=', user, ' host=', host, ' port=', port, ' password=', pwd)

library(sf)
data(meuse)
st_write(st_as_sf(meuse, coords = c("x","y")), dsn = DSN,  layer = "testinglayer")

或更改 host <- '127.0.0.1'至 host <- "localhost" ？
