The LEFT() function extracts a sub-string of a specified length from the beginning of a string.
- expression evaluates to the string from which the sub string is extracted.
- length is the number of extracted characters if length is less than 1, LEFT() returns null.
The LEFT function is equivalent to sub-string extraction starting from the first character position, i.e. expression[1,length]
An example of use is as:
STR_VAL =" Today's Brush is Tomorrows Forest.- Bemba Proverb" CRT LEFT(STR_VAL, 14) CRT DQUOTE(LEFT(STR_VAL,999)) CRT DQUOTE(LEFT(STR_VAL,0))
Today's Brush " Today's Brush is Tomorrows Forest.- Bemba Proverb" ""
to the screen.
