how to use trim in access 2013 to cut extra spaces

hi

i have some strange problem that when i make with a query for example:
NSERT INTO IskitTemp ( ProductName ) Select ProductName From ProductTbl

Open in new window

i get a list with  all products name with extra spaces that increase the character in the productName field to  250 characters (like the Restriction of The maximum amount of characters that can stored in the product name in the producttbl, but in the producttbl it's dosn't have so much  spaces  so why in iskittemp is so much spaces ?

Hi,

What is Definition of Product Name In the ProductTbl?

EDIT Are you using VARCHAR(n)  because CHAR(n) will add blanks at the end?

INSERT INTO IskitTemp ( ProductName ) Select Trim(ProductName) From ProductTbl 

Open in new window

i create it with sql string :

the Definition of Product Name In the ProductTbl is short text field size (255)

the iskttemp i create with a sql string like this
CREATE TABLE  (ProductName CHAR (255))

Open in new window

Hi,

With CHAR it adds Blank Space to create a 255 Character Long Field, pls use VARCHAR
