The position of characters in the text indexes beginning at zero. That means the last character in the text has the index equal to (LEN(text)-1).
To use a literal text as an argument of a function, enclose the text in quotes (“ string_constant ”).
FIND(find_text, within_text, start_index) Locates the argument find_text in the argument within_text and returns the starting position of find_text in within_text. The start_index argument specifies the character at which the search starts. If find_text is not found, the function returns -1. |
LEFT(text, num_chars) Returns the first num_chars characters of the argument text. |
MID( text, start_at, num_chars) Returns num_chars characters from the argument text, starting from the position start_at. |
RIGHT( text, num_chars) Returns the last num_chars characters of the argument text. |
LEN(text) Returns the number of characters (length) of the argument text. |
LOWER(text) Returns the argument text, converted completely to lower case. |
UPPER(text) Returns the argument text, converted completely to upper case letters. |
REPLACE(original_text,start_position,num_chars,inserted_string) Returns a text string created by way of replacing num_chars characters in original_text, with inserted_string, starting at start_postion. |
TRIM(text) Returns a text string with all leading and trailing spaces from the argument text removed. |
