Orafce:兼容Oracle的函数。比如date函数(next_day,last_day,trunc,round等)、字符串函数、一些包DBMS_ALERT, DBMS_OUTPUT, UTL_FILE, DBMS_PIPE等。 Ora2pg:Perl脚本,兼容schema。连接Oracle,提取结构,产生SQL语句然后加载到PG。 Oracle to postgres:不使用ODBC和其他中间件。转换表结构、数据、索引、主键和外键。

When rounding values, the NUMBER type rounds ties away from zero, while (on most machines) the REAL and DOUBLE PRECISION types round ties to the nearest even number. For example: → WrapCopy SELECT x, round(x::numeric) AS num_round, round(x::double precision) AS dbl_round FROM generate...
