Try:

SELECT LEFT(Products.Number, InStr(1, Products.Number, '.'))
FROM Products
0

Actually, that may include the period in the selection, so you may need to add a -1 to the position:

SELECT LEFT(Products.Number, (InStr(1, Products.Number, '.')-1))
FROM Products
0

You could use a CASE statement, something like:

SELECT CASE WHEN (InStr(1, Products.Number, '.') > 0) THEN LEFT(Products.Number, (InStr(1, Products.Number, '.')-1)) ELSE Products.Number) END

Oops, looks like a missing parenthesis:

SELECT CASE WHEN ((InStr(1, Products.Number, '.') > 0) THEN LEFT(Products.Number, (InStr(1, Products.Number, '.')-1)) ELSE Products.Number) END

If you're running it in Access,  you could use the IIF function instead:

SELECT IIF(InStr(1, Products.Number, '.') > 0, LEFT(Products.Number, (InStr(1, Products.Number, '.')-1)), Products.Number)
FROM Products
