我需要完全导出 12.2 数据库。最近我们在其中放置了 2 个表，其中有超过 400 万条记录将保持静态。我想将它们从每日 EXPDP 中删除，因为它们已离线存档。

此 EXPDP 通过计划任务启动并调用一系列批处理文件，这些批处理文件具有从批处理文件传递到批处理文件的已定义变量。这会产生一系列日志和存档文件，这些文件在更大的方案中很重要。

我在没有 .PAR 文件的情况下执行此操作，因为 .PAR 文件似乎不喜欢批处理文件中定义的任何 VARIABLE 名称。

我可以在命令提示符下毫无问题地运行它，但是如果我通过批处理调用它，我会收到错误

** LRM-00111：没有值'table:"LIK'的结束报价**

EXPDP *******/********@%dbname% FULL=Y exclude=statistics exclude=table:\"LIKE\'%_80\'\" DUMPFILE=%bckupdate%.dmp LOGFILE=%bckupdate%.log reuse_dumpfiles=yes

关于如何在 PAR 文件中使用变量名（如 %DBNAME%）或批处理文件的正确格式的任何有用提示将不胜感激。

你可以试试这个脚本 expdp_powershell.ps1

例如

E:\upwork\stackoverflow\expdp_powershell>powershell ./expdp_powershell.ps1   -user_name system -user_password manager -connect_string test -exclude table:\"LIKE\'%_80\'\"

或者

E:\upwork\stackoverflow\expdp_powershell>powershell  ./expdp_powershell.ps1

脚本 expdp_powershell.ps1

param(
[string]$user_name = "system"
, 
[string]$user_password = "manager"
,
[string]$connect_string = "TEST"
, 
[string]$export_mode = "FULL=Y" 
,
[string]$exclude = "table:\""LIKE \'%_80\'\""" 
)

$date_time_log = Get-Date -Format "yyyyMMddHHmmss" 



$DUMPFILE = "backup" + $date_time_log + ".dmp"
$LOGFILE = "backup_log" + $date_time_log + ".log"
$reuse_dumpfiles = "yes"
$DIRECTORY="DATA_PUMP_DIR"

echo $exclude

EXPDP $user_name/$user_password@$connect_string $export_mode exclude=statistics exclude=$exclude DIRECTORY=$DIRECTORY DUMPFILE=$DUMPFILE LOGFILE=$LOGFILE reuse_dumpfiles=$reuse_dumpfiles

例如输出

E:\upwork\stackoverflow\expdp_powershell>powershell ./expdp_powershell.ps1   -user_name system -user_password manager -connect_string test -exclude table:\"LIKE\'%_80\'\"
table:\"LIKE \'%_80\'\"
