Both char1 and char2 can be any of the datatypes CHAR, VARCHAR2, NCHAR, NVARCHAR2, CLOB, or NCLOB. The string returned is in the same character set as char1.

CONCAT - Oracle

Oracle - Concatenate Two Fields with a Space. While in the previous example, the requested result - merging two values from two different columns - has been achieved, the end result is still quite unreadable, as we have no space seperator between the product's name and its price To concatenate strings, you pass the strings as a list comma-separated arguments to the function. The CONCAT function returns a string which is the combination of the input strings. It returns NULL if one of the argument is NULL. (To handle NULL values more effectively you can use the IS NULL operator or COALESCE and NULLIF functions.). Most relational database systems support the CONCAT. CONCAT () returns NULL if any argument is NULL. A NULL parameter hides all information contained in other parameters from the result. Sometimes this is not desirable; to avoid this, you can: Use the CONCAT_WS () function with an empty separator, because that function is NULL -safe Re: Concatenate 2 XMLType Madhusudhan Reddy N Mar 25, 2013 11:52 AM ( in response to JackK ) Hi odie, how to print these two files into the below format

Oracle. Oracle uses the CONCAT(string1, string2) function or the || operator.
