RPAD function returns the string right-padded to the specified number of characters. RPAD accepts 2 or 3 parameters in PostgreSQL.
SQL Server does not have RPAD function but you can use expressions with LEFT and REPLICATE functions to implement RPAD, see examples below.
PostgreSQL:
-- Pad string with blanks (default) SELECT RPAD('abc', 7); # abc (4 blanks follow) -- Pad string with * SELECT RPAD('abc', 7, '*'); # abc****
SQL Server:
-- Pad string with blanks SELECT LEFT('abc' + REPLICATE(' ', 7), 7); # abc (4 blanks follow) -- Pad string with * SELECT LEFT('abc' + REPLICATE('*', 7), 7); # abc****
