account_holder = CASE LEN(RTRIM(LTRIM(UPPER(ISNULL(I.account_number_sterling, ''))))) + LEN(RTRIM(LTRIM(UPPER(ISNULL(I.account_number_euro, ''))))) + LEN(RTRIM(LTRIM(UPPER(ISNULL(I.account_number_usdollar, ''))))) WHEN 0 Then 0 Else 1 END,

account_number_sterling = RTRIM(LTRIM(UPPER(ISNULL(I.account_number_sterling, '')))),

account_number_euro = RTRIM(LTRIM(UPPER(ISNULL(I.account_number_euro, '')))),

account_number_usdollar = RTRIM(LTRIM(UPPER(ISNULL(I.account_number_usdollar, '')))),

company_name = RTRIM(LTRIM(UPPER(REPLACE(REPLACE(I.company_name, ',', ' '), '.', ' ')))),

address1 = RTRIM(LTRIM(UPPER(REPLACE(REPLACE(I.address1, ',', ' '), '.', ' ')))),
