T_sys_client
1. Create a temporary table first
create table tmp as select * from t_sys_client where 1=0;2. Insert the queried records into the temporary table
Insert into TMP select * From t_sys_client as of Timestamp sysdate-10/1440; -- Data 10 minutes agoSelect * From T2 as of Timestamp sysdate-1/1440 --> 1 represents 1 minute ago, change to 5 represents 5 minutes ago
At this time, it is your previous

The query to be executed is:

Workaround:
1. Create a folder tmp (such as c:/php/tmp) in the PHP directory, set the TMP property to ervery one Full control2. In php.ini find Session.save_path this line, set into Session.save_path = "c:/php/tmp", and remove the semicolon before
The above c:/php/tmp according to your actual situation set

Setting this value to 1; When the session. gc_pisor value is 100 will give you approximately a 1% chance; The gc will run on any give request.

Define the proportion of the 'garbage recycl' process starting at each session initialization.The ratio is determined by gc_probability/gc_divisor,For example,. 1/100 means that there is a 1% chance to start the 'garbage collection 'process each time a request is sent.

How does the session exist on the server side (typically Apache with PHP module)?By default, PHP will save the session in the/tmp directory, the file name looks like this: sess_01aab840166fd1dc253e3b4a3f0b8381.

Sets the lifetime of the saved session file, and after this parameter is set seconds, the saved data is considered ' garbage ' and cleaned up by the garbage collector. The criterion is the last time the data is accessed (for the FAT file system is the last time the data was refreshed). If multiple scripts share the same Session.save_path directory but session.gc_maxlifetime differ, the minimum values in all session.gc
