Oracle full EXPORT with exclude and NOT using par file

Question

I need to do a full export of a 12.2 database. Recently we placed 2 tables in it with over 4 million records that will remain static. I'd like to eliminate them from the daily EXPDP as they have been archived offline.

This EXPDP is launched via a scheduled task and calls a series of batch files that have defined variables that are passed from batch file to batch file. This produces a series of log and archive files important in the larger scheme of things.

I do this without a .PAR file as the .PAR files does not seem to like any VARIABLE names defined in the batch files.

I can run this at the command prompt without issue, but if I call it via a batch I get an error

** LRM-00111: no closing quote for value 'table:"LIK' **

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

Any helpful hints on how to either use a variable name (as in %DBNAME%) in the PAR file or proper formatting for the batch file would be appreciated.

I think the Oracle documentation says something vague about being careful about how to escape single and double-quotes "depending on platform" when using command line parameters. Worse comes to worst, your batch file could create the .PAR file on the fly, before invoking `expdp`. Also, is `%_80` supposed to match anything up to an underscore character followed by `80` at the end? If so, you need to do something similar to `LIKE\'%!_80\' ESCAPE \'!\'` — Mark Stewart, Jan 08 '21 at 23:24

You can try this script expdp_powershell.ps1

For example

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

or

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

Script 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

For example output

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\'\"
