    -- The GetNth method is handy for getting parts from delimited strings.
    -- For example:

    DECLARE @sb int
    EXEC @hr = sp_OACreate 'Chilkat.StringBuilder', @sb OUT
    IF @hr <> 0
    BEGIN
        PRINT 'Failed to create ActiveX component'

    SELECT @delimiterChar = ','
    DECLARE @exceptDoubleQuoted int
    SELECT @exceptDoubleQuoted = 1
    DECLARE @exceptEscaped int
    SELECT @exceptEscaped = 1

    -- Prints "[red]"

    EXEC sp_OAMethod @sb, 'GetNth', @sTmp0 OUT, 0, @delimiterChar, @exceptDoubleQuoted, @exceptEscaped

    PRINT '[' + @sTmp0 + ']'

    -- Prints "[blue]"

    EXEC sp_OAMethod @sb, 'GetNth', @sTmp0 OUT, 1, @delimiterChar, @exceptDoubleQuoted, @exceptEscaped

    PRINT '[' + @sTmp0 + ']'

    EXEC sp_OAMethod @sb, 'GetNth', @sTmp0 OUT, 2, @delimiterChar, @exceptDoubleQuoted, @exceptEscaped

    PRINT '[' + @sTmp0 + ']'

    -- Prints "[]"

    EXEC sp_OAMethod @sb, 'GetNth', @sTmp0 OUT, 3, @delimiterChar, @exceptDoubleQuoted, @exceptEscaped
