SQL Server TRIM character

Question

I have the following string: \'BOB*\', how do I trim the * so it shows up as \'BOB\'

I tried the RTRIM(\'BOB*\',\'*\') but does not work as says needs only 1 paramet

Answer 1

How about.. (in this case to trim off trailing comma or period)

For a variable:

-- Trim commas and full stops from end of City
WHILE RIGHT(@CITY, 1) IN (',', '.'))    
    SET @CITY = LEFT(@CITY, LEN(@CITY)-1)  

For table values:

-- Trim commas and full stops from end of City
WHILE EXISTS (SELECT 1 FROM [sap_out_address] WHERE RIGHT([CITY], 1) IN (',', '.'))     
    UPDATE [sap_out_address]    
    SET [CITY] = LEFT([CITY], LEN([CITY])-1)  
    WHERE RIGHT([CITY], 1) IN (',', '.')
