ORACLE 11G，表TB_QSD_ZP有建表语句的部分(从dbms_metadata.get_ddl得到)：

 TABLESPACE "USERS"
LOB ("CONTENT") STORE AS SECUREFILE (
TABLESPACE "USERS" ENABLE STORAGE IN ROW
CHUNK 8192
NOCACHE LOGGING NOCOMPRESS KEEP_DUPLICATES )

现在这个CONTENT字段，想改成NOLOGGING，写语句如下：

alter table XXX.tb_qsd_zp modify LOB("CONTENT" BLOB) STORE AS SECUREFILE (TABLESPACE "USERS" ENABLE STORAGE IN ROW
CHUNK 8192 NOCACHE NOLOGGING NOCOMPRESS KEEP_DUPLICATES);
alter table XXX.tb_qsd_zp modify LOB(CONTENT) STORE (NOLOGGING);
alter table XXX.tb_qsd_zp modify LOB("CONTENT") STORE AS SECUREFILE(NOLOGGING);

都报同样错

ERROR at line 1:
ORA-00907: missing right parenthesis

求大师指教！
