Load CLOB data

OraCmd can load CLOB data.

A Short Example

This section contains a short example showing how OraCmd load CLOB data.

The Data

The particular file (clob.txt) used for this example contains CLOB data. It's a delimited text file.

	1,Hello CLOB
	2,Not everybody use CLOB
	3,But some time we should use it

We used the following SQL statement to create the table into which all this data will be loaded:

	create table T_CLOB
	  ID     NUMBER,

OraCmd commmand

	load table=t_clob datafile="E:\test\clob.txt" delimiter="," loadtype=append

Or a batch file(replace the userid with your own database user info. The lines wrap in this page, but in the file is 1 line.):

	"C:\Program files\OraCmd\OraCmd" userid=hr/hr@localhost:1521:xe task=load 
	table=t_clob datafile="E:\test\clob.txt" delimiter="," loadtype=append 
	quit=y log="E:\test\load_clob.log"
