mysql建表语句转为oracle建表语句
单引号'变双引号"
comment内容去掉
varchar变varchar2
double/int之类的数字变number
PRIMARY KEY ("kc_no")语句变 CONSTRAINT "kc_no" PRIMARY KEY ("kc_no")
select jihua_no from zhou.px_kecheng_jihua
where status<>-1
and input_date between "0001-01-01" and "9999-12-31"
order by input_date desc
mysql语句转为oracle语句日期不再是字符串需要to_date
select jihua_no from px_kecheng_jihua
where status<>-1
and input_date between to_date('0001-01-01','yyyy-mm-dd') and to_date('9999-12-31','yyyy-mm-dd')
order by input_date desc
用java设置日期
pStmt.setDate(13,new java.sql.Date(Calendar.getInstance().getTimeInMillis()));
pStmt.setDate(14,new java.sql.Date(order.getPxDate().getTime()));
驱动程序名称
MySQL-AB JDBC Driver
Oracle JDBC driver
可以通过
conn.getMetaData().getDriverName().contains("MySQL")判断是何数据库
例如:
if(conn.getMetaData().getDriverName().contains("MySQL")==true)
sqlStr="select jihua_no from px_kecheng_jihua where status<>-1 and "+column+" like ? and input_date between ? and ? order by input_date desc";
if(conn.getMetaData().getDriverName().contains("Oracle")==true)
sqlStr="select jihua_no from px_kecheng_jihua where status<>-1 and "+column+" like ? and input_date between to_date(?,'yyyy-mm-dd') and to_date(?,'yyyy-mm-dd') order by input_date desc";
