IMP時 ORA-01741 illegal zero-length identifier

環境：oracle 9.2.0.1匯入； 從9.2.0.4庫上匯出（匯出客戶端是9.2.0.1）；

同義詞帶dblink,且table_owner為空的imp時報錯，發現少部分能正常匯入；與dblink是否有效無關；
解決辦法，手工建立同義詞：

IMP-00017: following statement failed with ORACLE error 1741:
 "CREATE SYNONYM "MIE_GOODS_DECL" FOR ""."MIE_GOODS_DECL"@"CEMS_MIE""
IMP-00003: ORACLE error 1741 encountered
ORA-01741: illegal zero-length identifier

查詢語句：
select *
 from dba_synonyms d where D.db_link IS NOT NULL  AND D.table_owner IS NULL  and  d.owner ='CEMS';
 
select 'CREATE OR REPLACE SYNONYM '||SYNONYM_NAME||' FOR '||TABLE_NAME||'@'||db_link||';'
 from dba_synonyms d where D.db_link IS NOT NULL  AND D.table_owner IS NULL  and  d.owner ='CEMS';

後在CEMS使用者下執行語句；
