Description
The BETWEEN() function returns true (.T.) if the value of a specified expression lies in the range delimited by two other expressions all of the same data type. The BETWEEN() function operates on Character, Date and Numeric expressions.
| Parameters | Description |
|---|---|
| <exp1> | The expression to be checked. |
| <exp2> | Expression representing the range minimum. |
| <exp3> | Expression representing the range maximum. |
The <exp1> must be equal to or more than <exp2> and equal to or less than <exp3> for BETWEEN() to return true (.T). If <exp1> is not within this range, BETWEEN() returns false (.F.).
Example
? between(date(),date()-10,date()+10) .T. ? between("A", "A", "Z") .T. ? between(10,1,9) .F.
