Oracle processes Clob data warehouse receiving (String warehouse receiving)

You can search for a bunch of references from the Internet, either in unknown or not. You can load a pile of data into the database. Please refer to the final:

Insert into CP_V_INFO "+
"(ID," +
"PROJECT_ID," +
......
"V_INFO," +
......
"VERSION) values (?,?,?,?,?,?,?,?,?,?, "+
"?,?, EMPTY_CLOB (),?,?,?,?,?,?,?, "+
"?,?,?,?,?,?,?,?,?,?, "+
"?) ";
This.cdcDao.exe cuteSQL (SQL, v7Info. getId (),
V7Info. getProjectId (),......
);
// Insert the data first and use EMPTY_CLOB () to insert the data in this field.
// Then for update
String update_ SQL = "select V_INFO from CP_V_INFO where ID = '" + v7Info. getId () + "' for update ";
This.cdcDao.exe cuteClobSQL (update_ SQL, "V_INFO", v7Info. getvInfoStr ());

After numerous difficulties, my colleagues said, "Why should I change the underlying code ?". After a pleasant keyboard sound, the original method was changed. This field is inserted normally with a String. The result is: the database is imported normally. , And tears !!!!

 

String SQL = "insert into CP_V_INFO" +
"(ID," +
......
"V_INFO," +
......
"VERSION) values (?,?,?,?,?,?,?,?,?,?, "+

This.cdcDao.exe cuteSQL (SQL, v7Info. getId (),

V7Info. getvInfo (), // String type

V7Info. getVersion ());
