There might be another DB or two that takes the above syntax, but it's certainly nowhere to be found in the SQL spec. SQL99 defines the numeric types as <exact numeric type> ::= NUMERIC [ <left paren> <precision> [ <comma> <scale> ] <right paren> ] | DECIMAL [ <left paren> <precision> [ <comma> <scale> ] <right paren> ] | DEC [ <left paren> <precision> [ <comma> <scale> ] <right paren> ] | INTEGER | INT | SMALLINT <approximate numeric type> ::= FLOAT [ <left paren> <precision> <right paren> ] | REAL | DOUBLE PRECISION INTEGER is stated to have scale zero and implementation-defined precision. regards, tom lane
