Oracle database version is 10.2 and I have tried with oracle jdbc thin driver version 10.2 and 11.1.The parameter is Timestamp, and I expected that no time conversions will be done on the way. The database column type is DATE, but I also checked it with TIMESTAMP column type with the ...

仍然是 FULL TABLE SCAN 。 罪魁祸首:setTimestamp() 把值绑定为 TIMESTAMP 类型,这样和 DATA 类型比较的时候,CBO 就会选择全表扫描。 通过Trace 能观察到该异常行为。TIMESTAMP 在 Oracle JDBC 9.2.0.1 上就有了,连续几个版本其实都有类似的问题。 解决办法:使用 setString() 而不是 setTimestamp() 方法。
timestamp java.sql.timestamp 如果oracle是date,而java中用sql.date的话,会丢失时分秒,所以可以另想办法 比如:java中是日期字符串,后台用to_date(datestr,'yyyy-mm-dd hh24:mi:ss')来转换 当然oracle中的date类型在获取的时候也会自动去掉时分秒,所以可以用to_char函数来处理 带时分秒的,最好的方法当然是...
TIMESTAMP_COL_NONE = '2007-01-01 01:01:01.999'works because the database sees this: <type datetime> = <type varchar literal> default casting rule: convert varchar literal to datetime, which results in '2007-01-01 01:01:02.000', and matches the value in the database. ...
