LEFT(cExpression, nExpression) |
Parameters
- cExpression
- Specifies the character expression that LEFT(В ) returns characters from.
- nExpression

If nExpression is negative or 0, LEFT(В ) returns an empty string. LEFT(В ) uses a starting position of 1 and is identical to SUBSTR(В ).
Return Value
Character. LEFT(В ) returns a character string.

The following example uses two different ways to display the string result from the LEFT(В ) function, which returns the first four letters in the string, "Redmond, WA":
| В |  Copy Code |
|---|---|
? LEFT('Redmond, WA', 4) && Displays the string, Redm.
myString = LEFT('Redmond, WA', 4) && Stores result in myString.
? myString && Displays result in myString. | |
