How to import a .dmp file (Oracle) into MySql DB?

由 こ雲淡風輕ζ 提交于 2019-12-10 02:52:46
问题 The .dmp is a dump of a table built in Oracle 10g (Express Edition) and one of the fields is of CLOB type. I was trying to simply export the table to xml/csv files then import it to the MySql, but the export simply ignored the CLOB field... (I was using sqldeveloper for that). I noticed this post explaining how to extract the CLOB to text file but it seems to miss the handling of the other fields or at least the primary key fields. can it be adopted to create a csv of the complete table? (I

I have the following query (column log is of type CLOB): UPDATE table SET log=? where id=? The query above works fine when using the setAsciiStream method to put a value longer than 4000 characters into the log column. But instead of replacing the value, I want to append it, hence my query looks like this: UPDATE table SET log=log||?||chr(10) where id=? The above query DOES NOT work any more and I get the following error: java.sql.SQLException: ORA-01461: can bind a LONG value only for insert into a LONG column It looks to me like you have to use a PL/SQL block to do what you want.
