尝试将表写入非默认架构时，SQL函数不起作用

标签： r sql-server r-dbi

我正在尝试向SQL Server 2017中的非默认架构写入表。我正在使用RStudio文档来了解最佳做法：https://db.rstudio.com/best-practices/schema/#write-non-temporary-tables。

但是，当我遵循他们的指南时，会出现以下错误：Error: Can't unquote EXISTING_SCHEMA.newTbleIris

编辑

经过一番挖掘，我取得了一些进步。但是问题尚未完全解决。我发现Id（）函数允许我读取但不能写入。下面的例子。我在尝试编写时遇到的错误是：

Error in connection_sql_tables(conn@ptr, catalog_name = if ("catalog" %in% : nanodbc/nanodbc.cpp:2525: 24000: [Microsoft][ODBC SQL Server Driver]Invalid cursor state

新的可复制示例

library(odbc)
library(dbplyr)
library(dplyr)
library(DBI)

con <- dbConnect(odbc(),
                 Driver = "SQL SERVER",
                 Server = "SERVER_NAME",
                 Database = "DB_NAME",
                 UID = "USER_NAME",
                 PWD = "PASSWORD")

# Works assuming you already have iris table in EXISTING SCHEMA.
# I did this not in R because I cannot currently write to a non-default schema in R.
dbReadTable(con, Id(schema = "EXISTING_SCHEMA", name = "iris"))

# Still cannot write to non-default schema Throws an error.
dbWriteTable(con, Id(schema = "nycDoe", name = "iris"), iris)

可复制示例

library(odbc)
library(dbplyr)
library(dplyr)
library(DBI)

con <- dbConnect(odbc(),
                 Driver = "SQL SERVER",
                 Server = "SERVER_NAME",
                 Database = "DB_NAME",
                 UID = "USER_NAME",
                 PWD = "PASSWORD")

# this works, writing to default schema
dbWriteTable(con, SQL("newTbleIris"), iris)

# this does NOT work and gives error mentioned above
dbWriteTable(con, SQL("EXISTING_SCHEMA.newTbleIris"), iris)

我找到了一个简单的解决方法。只需按照以下步骤操作即可：

首先，使用默认架构编写表： dbWriteTable(con, "newTbleIris", iris)

并将其插入具有非默认架构的新数据库中，但这一次使用dbGetQuery函数：

dbGetQuery(con, "SELECT * INTO [schema].newTbleIris FROM newTbleIris")

就是这样！您的表现在将显示为非默认架构。

现在，您可以执行以下操作，删除使用默认架构首次创建的第一个表 dbGetQuery(con, "DROP TABLE newTbleIris")
