Notes:
-
The SUBSTRING() function in SQL is used to extracts characters from a string.
- Syntax : SUBSTRING(string, start_index, length_of_character)
- Above Syntax string parameter is the string passed for extraction, start_index is the index where the extraction starts length_of_character is the length of characters to extract from string.
- start index of extraction for all string in SQL starting index is always 1.
- If you pass negative number in length parameter it will throw and error.
