ORA-01858: a non-numeric character was found where a numeric was expected
parfile.par
directory=Data_Pump
dumpfile=test.dmp
cluster=n
logfile=test.log
tables=OWNER.TABLE
query="WHERE "sys_created_on" > to_date('01/05/2018 00:00:00','DD/MM/YYYY HH24:MI:SS')"
The following syntax were not successful either in the case above:
query='WHERE \"sys_created_on\" > to_date('01/05/2018 00:00:00','DD/MM/YYYY HH24:MI:SS')'
query="WHERE '\"sys_created_on\"' > to_date('01/05/2018 00:00:00','DD/MM/YYYY HH24:MI:SS')"
QUERY="WHERE 'sys_created_on' > to_date('01_05_2018 00_00_00','DD_MM_YYYY HH24_MI_SS')"
query="WHERE '\"sys_created_on\"' > to_date('01_05_2018 00_00_00','DD/MM/YYYY HH24_MI_SS')"
query="WHERE \"sys_created_on\" > to_date("01/05/2018 00:00:00","DD/MM/YYYY HH24:MI:SS")"
query='WHERE "sys_created_on" > to_date("01/05/2018 00:00:00","DD/MM/YYYY HH24:MI:SS")'
QUERY=\"WHERE \'sys_created_on\' > to_date\(\'01_05_2018 00_00_00\',\'DD_MM_YYYY HH24_MI_SS\'\)\"
QUERY="WHERE \'sys_created_on\' > to_date\(\'01_05_2018 00_00_00\',\'DD_MM_YYYY HH24_MI_SS\'\)"
