The typical solution is not to use CHAR(n) and use a VARCHAR2(n) datatype.. But what if you have both? If the column is of CHAR(n) datatype and the string you have entered does not have n characters then Oracle will pad the data with space (CHR(32)) characters until it has exactly n characters.. What if you use a recursive TRIM function? SELECT REPLACE( REPLACE( REPLACE( RTRIM( COL_CONTENT ), CHR(10), '\n' ), CHR(9… Select * from LOCATION; Select all Open in new window. Connected to: Oracle9i Enterprise Edition Release 9.2.0.6.0 - 64bit Production With the Partitioning, OLAP and Oracle Data Mining options JServer Release 9.2.0.6.0 - Production SQL… Carriage returns = 13 Line Feeds = 10 Tabs = 9 (and other ascii codes..) Once you know the code, getting them from the database is easy. I am looking for some much needed advice on what options I can use to replace special characters Carriage Return (hex 0D) and Line Feed (hex 25) when loading them into Oracle using SQL Loader. "trim" function trims only single character. The main issue is that TRIM only removes one type of character – you can only specify a single character for TRIM to remove.

There is a function chr() … Hi All, i have this simple SQL below to extract all the information. I learnt that there is no easy way to trim multiple characters in Oracle.

We've a table with a varchar2(100) column, that occasionally contains carriage-return & line-feeds. It returns the character based on the NUMBER code. Asked: May 02, 2000 - 1:20 pm UTC. Or it is mixed with spaces and tab characters (CHR(9))? I need to trim New Line (Chr(13) and Chr(10) and Tab space from the beginning and end of a String) in an Oracle query.
