使用 不同的 table 和数据文件 尝试此命令确实有效 ，此时错误消息是太简短了，无法提供更多调试信息（以前从未使用过 BCP 实用程序）。如果有人有使用此工具的经验，任何调试建议或如何解决此问题将不胜感激。
进一步调试后，发现当使用BCP将tsv文件复制到MSSQL DB中时，tsv中的文字'null'值被导入为字符串和（我假设）这就是导致错误的原因，因为目标 table 中的某些字段需要数值等（在使用 BCP 之前，正在使用一个以更隐蔽的方式处理此问题的进程).将命令更改为
形式
echo "Replacing null literal values with empty chars"
NULL_WITH_TAB="null\t"
TAB="\t"
sed -i -e "s/$NULL_WITH_TAB/$TAB/g" $filename
/opt/mssql-tools/bin/bcp "$TABLE" in "$filename" \
$TO_SERVER_ODBCDSN \

-P $PASSWORD \
-d $DB \
$RECOMMEDED_IMPORT_MODE \
-t "\t" \
-e /home/me/projects/bcp-experiments/examples/recent-err-row.log
修复了问题（将 TSV 中的“null”替换为文字制表符）。如果有人知道将来如何强制从 BCP 发出更详细的错误消息，或者其他类型的问题会引发此类模糊错误，请告诉我。

使用 不同的 table 和数据文件 尝试此命令确实有效 ，此时错误消息是太简短了，无法提供更多调试信息（以前从未使用过 BCP 实用程序）。如果有人有使用此工具的经验，任何调试建议或如何解决此问题将不胜感激。
进一步调试后，发现当使用BCP将tsv文件复制到MSSQL DB中时，tsv中的文字'null'值被导入为字符串和（我假设）这就是导致错误的原因，因为目标 table 中的某些字段需要数值等（在使用 BCP 之前，正在使用一个以更隐蔽的方式处理此问题的进程).将命令更改为
形式 echo "Replacing null literal values with empty chars"
NULL_WITH_TAB="null\t"
TAB="\t"
sed -i -e "s/$NULL_WITH_TAB/$TAB/g" $filename
/opt/mssql-tools/bin/bcp "$TABLE" in "$filename" \
$TO_SERVER_ODBCDSN \
-U $USER \
-P $PASSWORD \
-d $DB \
$RECOMMEDED_IMPORT_MODE \
-t "\t" \
-e /home/me/projects/bcp-experiments/examples/recent-err-row.log
修复了问题（将 TSV 中的“null”替换为文字制表符）。如果有人知道将来如何强制从 BCP 发出更详细的错误消息，或者其他类型的问题会引发此类模糊错误，请告诉我。
