Purpose
Function to return the single row result of an SQL statement
Syntax
SQLVALUES(<SQL statement>)
See Also
Description
The SQLVALUES() function executes the <SQL statement> and returns the result as a string. Multiple values from a singleton select are returned as a comma-separated list.
If the <SQL statement> returns multiple rows, only the values from the first row are returned, but the results of all rows are available in the automatically created _sqlvalues array.
Example
open database southwind cTotal = sqlvalues("select max(available), min(available) from example") // Access multiple row results sqlvalues('select state from example group by state') ? astring(_sqlvalues) AL,AR,CA,CO,CT,FL,GA,IA,IL,KY,LA,MA,MD,ME,NH,NJ,NY,OH,PA,VA,WI
