Question

java中如何将大于10000的字符串，插入oracle数据库中的blob类型字段中？

Answer 1

不要用blob，用clob类型。先插入一个empty_clob()，然后用Statement myStmt = conn.createStatement();
ResultSet clobResultSet=myStmt.executeQuery("SELECT "+strCLOBColName
+" FROM "+strTable
+" WHERE "+ strIdColName +" ='" + strIdValue+ "' FOR UPDATE ");
CLOB myClob = (oracle.sql.CLOB)clobResultSet.getClob(strCLOBColName);
myClob.putString(1,strBuff);
myStmt.execute("COMMIT");
clobResultSet.close();
myStmt.close();
conn.setAutoCommit(true);
