管道化表函数必须返回一个集合。在函数中,PIPE ROW 语句被用来返回该集合的单个元素,该函数必须以一个空的 RETURN 语句结束,以表明它已经完成。一旦我们创建了上述函数,我们就可以使用 TABLE 操作符从 SQL 查询中调用它。 管道化表函数经常被用来把数据从一种类型转化成另一种类型。 下面是用 Pipelined Table 实现...
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。 ora_migrator:PL/pgSQL...

不支持using语法,可通过把参数拼接到SQL串中来解决。 数据库标识符使用quote_ident包裹,数值使用quote_literal包裹。 示例: EXECUTE 'UPDATE employees_temp SET commission_pct = :x' USING a_null; 转换成: EXECUTE 'UPDATE employees_temp SET commission_pct = ' || quote...
The underscore character needs to appear in quotes, and the backslash is used before each of the quotes to escape those quotes (because the entire string appears within a set of double quotes). exec_sql.sh. As mentioned earlier, it is possible to query the database from a shell script ...
