Hi Everyone,

I have this issue. I need to put a limit in number of rows per excel file.

For example :

The total rows in my table is 4116 but I only need 998 per excel file. So,

Excel 1 should be 998
Excel 2 should be 998
Excel 3 should be 998
Excel 4 should be 998
Excel 5 should only be 124

I already done the excel 1 to 4. However, the excel 5 still showing 998 rows even if i limit it only to 124.

Below is my code:
PROCEDURE fpr_forms_to_excel(p_block_name in varchar2 ,
														 p_path 			in varchar2 ,
														 p_file_name 	in varchar2 ) IS
-- Declare the OLE objects
	application 					OLE2.OBJ_TYPE;

	cell 									OLE2.OBJ_TYPE;
	range 								OLE2.OBJ_TYPE;
	range_col 						OLE2.OBJ_TYPE;

Please read OraFAQ Forum Guide and How to use [code] tags and make your code easier to read.
Also always post your Oracle version, with 4 decimals, as solution depends on it.
