Answer:

Explanation: 

REPLACE (text, search_string, replacement_string) Searches a text expression for a character string and, if found, replaces it with a specified replacement string The REPLACE Function The REPLACE function replaces all occurrences of a search item in a source string with a replacement term and returns the modified source string. If the length of the replacement term is different from that of the search item, then the lengths of the returned and source strings will be different. If the search string is not found, the source string is returned unchanged. Numeric and date literals and expressions are evaluated before being implicitly cast as characters when they occur as parameters to the REPLACE function. The REPLACE function takes three parameters, with the first two being mandatory. Its syntax is REPLACE (source string, search item, [replacement term]). If the replacement term parameter is omitted, each occurrence of the search item is removed from the source string. In other words, the search item is replaced by an empty string. . The following queries illustrate the REPLACE function with numeric and date expressions: Query 1: select replace(10000-3, '9', '85') from dual Query 2: select replace(sysdate, 'DEC', 'NOV') from dual

Answer:

Explanation: 

The SUBSTR(string, start position, number of characters) function accepts three parameters and returns a string consisting of the number of characters extracted from the source string, beginning at the specified start position: 

substr('http://www.domain.com', 12, 6) = domain 

The position at which the first character of the returned string begins. 

When position is 0 (zero), then it is treated as 1. 

When position is positive, then the function counts from the beginning of string to find the first character. 

When position is negative, then the function counts backward from the end of string. substring_length 

The length of the returned string. SUBSTR calculates lengths using characters as defined by the input character set. SUBSTRB uses bytes instead of characters. SUBSTRC uses 

Unicode complete characters. 

SUBSTR2 uses UCS2 code points. SUBSTR4 uses UCS4 code points. 

When you do not specify a value for this argument, then the function 

The INSTR(source string, search item, [start position], [nth occurrence of search item]) function returns a number that represents the position in the source string, beginning from the given start position, where the nth occurrence of the search item begins:
