包含带换行符的单元格的 sqlSave 表进入 Access
sqlSave tables containing cells with line breaks into Access
我有代码可以将多个数据帧导出到 Access 数据库中的各个 sheet。每个 sheet 中的一列包含包含多行字符串的单元格（即，使用“\r\n”通过 R 引用插入到字符串中的中断）。
我 运行 遇到的问题是 sqlSave 似乎想要截断字符串，以便访问中导出的单元格仅包含多行值的第一行。换行符对我的目的至关重要。想知道 how/if 我可以将包含多行字符串的列从 R 传递到 Access 中。

# write in table

根据评论，考虑将基础列更改为长文本（或备忘录）以容纳超过 255 个字符的短文本限制的所有字符数据。然后，运行 迁移您的数据框。请参阅 Access SQL 的 ALTER TABLE 声明。
sqlQuery(db_Out, "ALTER TABLE FVS_StandInit ALTER COLUMN FVSKeywords LONGTEXT")
sqlSave(db_Out, FVS_StandInit, tablename="FVS_StandInit", colnames=FALSE, rownames=FALSE)
我有代码可以将多个数据帧导出到 Access 数据库中的各个 sheet。每个 sheet 中的一列包含包含多行字符串的单元格（即，使用“\r\n”通过 R 引用插入到字符串中的中断）。
我 运行 遇到的问题是 sqlSave 似乎想要截断字符串，以便访问中导出的单元格仅包含多行值的第一行。换行符对我的目的至关重要。想知道 how/if 我可以将包含多行字符串的列从 R 传递到 Access 中。

代码示例：
# establish output dB connection
db_Out <- odbcConnectAccess2007("./Out_Database.accdb")
# write in table
sqlSave(db_Out,FVS_StandInit,tablename="FVS_StandInit",colnames=FALSE,rownames=FALSE)
