尝试通过bcp包中的mssql-tools将TSV文件数据复制到MSSQL DB中。获取以下形式的bcp错误日志：

因此，TSV中的字符应适合。使用cat -ne datafile.tsv可以看到行以$结尾，因此我对该文件进行的预处理是：
# remove header
sed -i 1d "$EXPORT_STAGE/$TABLENAME/$TABLENAME.TSV"
# remove DOS carriage return
sed -i "s/\r//g" "$EXPORT_STAGE/$TABLENAME/$TABLENAME.TSV"
# append etl date to data records
sed -i "s/$/\t$(date +%Y-%m-%d)/" "$EXPORT_STAGE/$TABLENAME/$TABLENAME.TSV"

任何人都可以帮助确定这里可能发生的事情吗？
答案 0 :(得分：1)
就像杰米和亚历克斯一样，BCP会将双引号解释为文本值的一部分，因此，原本应为单字符的字段例如。 Y被读为3宽字符串"Y"，因此溢出了目标DB中的字段（在这种情况下，它是期望的varchar(1)）。
*注释中的扩展对话对数据中的各种其他问题很有帮助，我认为对于调试BCP问题的其他人仍然有用，但是此双引号是该问题的主要问题。
