Hi Paul, >> Norman, I'm not sure what you mean by this bug--how does extracting DDL involve conversion from CLOB, etc.? Something like this : --DDL Script for TABLE "XXXXXX"."YYYYYYY" CREATE TABLE "XXXXXX"."YYYYYYY" ( <SNIP lots of columns here > , CONSTRAINT "YYYYYYY_FK1" <SNIP lots of constraints here> ) PCTFREE 10 PCTUSED 40 INITRANS 1 MAXTRANS 255 NOCOMPRESS NOLOGGING STORAGE ( <SNIP storage clauses here> BUFFER_POOL DEFAULT) TABLESPACE "MY_TABLESPACE" ORA-22835: Buffer too small for CLOB to CHAR or BLOB to RAW conversion (actual: 5112, maximum: 4000) I have to confess this is not my table, nor my generation of it either. It's one I know about but it was quite a long table - lots of columns and lots of constraints, storage clauses etc. It may be bug 2616047 but that applies to MVs apparently. It's not a problem I've ever had myself, my tables are a lot smaller when scripted :o) Cheers, Norman. Norman Dunbar. Contract Oracle DBA. Rivers House, Leeds.
