![]() Since next we will be learning how to multiplex control files in Oracle Database. Do make sure to subscribe to my YouTube channel. That is how you check what control file contains in Oracle Database. Loading multiple files into multiple tables in a singe control file. On successful execution, you will have the name and location of the trace file which has all the content of the control file in a user-readable format. fld2 DECODE(:fld1, hello, goodbye, :fld1) ) BEGINDATA hello, goodbye. In the end, we need the name and location of the trace file into which the ORADEBUG utility saved the control file content and we can find that like this â SQL> oradebug tracefile_name Let us setup a simple test case with some data which we will insert into a table through SQL Loader. SQL> alter session set events 'immediate trace name controlf level 9' In this short blog post, we will explain how to use Decode Function in the control file of SQL Loader to Load data. Step 4- Use the alter session statement to display the physical content of the control file. Step 3- Set the size of the trace file to unlimited SQ>ORADEBUG UNLIMIT Ä«y default, the size of the trace file is not set to unlimited. Step 2- Debug the current process SQL> ORADEBUG setmypid Hi, I need to decode an incoming value from the delimited file and insert the decoded value into the target table. Step 1- Connect With the database using the SYS user C>SQLPLUS / as SYSDBA See SQLLoader Express for more information. Note: You can also use SQLLoader without a control file this is known as SQLLoader express mode. The second way to read a control file is through the ORADEBUG utility of the Oracle Database. The SQLLoader control file is a text file that contains data definition language (DDL) instructions for a SQLLoader job. Now letâs check out the second way to read a control file in Oracle. You can change this name and location according to your preference. How SQLLoader expects that data to be formatted. The corresponding name/identifier of stackoverflow should be test or a foreign key to a table that contains test. ![]() But the names/identifier of the properties are unreadable. DDL is used to control the following aspects of a SQLLoader session: Where SQLLoader will find the data to load. The query select UTLRAW.CASTTOVARCHAR2 () from dual returns the string below: Here the values of the metadata are shown.On successful execution this statement will create a user-readable version of the Control file and save it into my D: drive with the name âtrace_cf.txtâ. The SQLLoader control file is a text file that contains data definition language (DDL) instructions. Functions code, eatest and oracle.least must always be prefixed by the schema name even if the oracle is before pgcatalog in the searchpath because these functions are implemented inside PostgreSQL parser and analyzer. Step 2- Write Alter Database Statement SQL>ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS 'D:\\trace_cf.txt'
