我正在尝试使用以下方法将数据框附加到 sql server 表中:
DBI::dbWriteTable(con_poc, "DEP_EVENTS", data_up, overwrite=FALSE, append = TRUE, verbose = TRUE, rownames = FALSE)
但是我在数据库中“日期”类型的列上出现错误。
Error in result_insert_dataframe(rs@ptr, values) :
nanodbc.cpp:1587: 22003: [Microsoft][ODBC SQL Server Driver]Numeric value out of range
我之前使用 as.POSIXct(example_date) 格式化了该列,但这似乎只适用于“日期时间”列
任何人都可以帮忙吗?
添加信息:
DEP_EVENTS:
DATA_REGION (varchar(50), not null)
EVENT_ID(PK, bigint, not null)
EVENT_NAME(varchar(200), not null)
FORECAST_STATUS(varchar(50), not null)
FORECAST_CYCLE(date, not null)
data_up <- data.frame(DATA_REGION = "America",
EVENT_NAME = "shiny deal",
FORECAST_STATUS = "Plan of Record",
FORECAST_CYCLE = as.Date("2017-07-07"))
DBI::dbWriteTable(con_poc, "DEP_EVENTS", data_up, overwrite=FALSE, append = TRUE, verbose = TRUE, rownames = FALSE)
Error in result_insert_dataframe(rs@ptr, values) :
nanodbc.cpp:1587: 22003: [Microsoft][ODBC SQL Server Driver]Numeric value out of range
我没有插入主键,因为我在尝试时收到以下错误
Error in result_insert_dataframe(rs@ptr, values) :
nanodbc.cpp:1587: 23000: [Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert explicit value for identity column in table 'DEP_EVENTS' when IDENTITY_INSERT is set to OFF.
也应要求:
str(data_up)
'data.frame': 1 obs. of 4 variables:
$ DATA_REGION : Factor w/ 1 level "America": 1
$ EVENT_NAME : Factor w/ 1 level "shiny deal": 1
$ FORECAST_STATUS: Factor w/ 1 level "Plan of Record": 1
$ FORECAST_CYCLE : Date, format: "2017-07-07"
我还尝试将因子列更改为字符,但错误没有变化。
