StrPCopy is defined for shortstring only.
So it will typecast the ansistring shortstring first, and then pass it
to strpcopy to copy it into the pchar.

Much to complicated. Remember that ansistrings are relatives of pchars,
and can be typecast to such beasts.

If the system will only read from the pchar, you can directly pass an

var s:ansistring;

S:='SELECT * FROM table WHERE NAME="'+Data[1].value+'"';
