To replace new line space in Oracle SQL, you can use the REPLACE function. Here's an example:
Let's say you have a table named "employees" with a column named "notes" that contains new line spaces represented by the "\n" character. To replace these with a space, you can use the following SQL query:
CODE:
UPDATE employees
SET notes = REPLACE(REPLACE(notes, CHAR(13), ''),CHAR(10),'');
In this query, the REPLACE function takes three arguments: the column name "notes", the CHAR(10) AND CHAR(13) function which represents a new line character in Oracle SQL,and a single space '' which is the replacement string.
The UPDATE statement updates the "notes" column in the "employees" table with the new values.
After running this query, any new line spaces in the "notes" column will be replaced with a single space.

To remove all occurrences of new line, carriage return, and tab characters from a string column in Oracle, we can combine them and replace with a space character using the concatenation sign "||" and REPLACE() function. Here's an example syntax:
REPLACE(string_column, CHR(10) || CHR(13) || CHR(9), ' ')
In the above syntax, string_column refers to the column name containing the string values. The CHR() function is used to generate ASCII values for new line (CHR(10)), carriage return (CHR(13)), and tab (CHR(9)) characters, which are then combined using the concatenation sign "||". The REPLACE() function then replaces all occurrences of the combined characters with a single space character.
For example, if we have a table named "employee" with a column named "address" containing string values with new line, carriage return, and tab characters, we can use the following query to replace them with a space character:
SELECT REPLACE(address, CHR(10) || CHR(13) || CHR(9), ' ')
FROM employee;
This query will return the "address" column with all occurrences of new line, carriage return, and tab characters replaced with a space character.
