mysql - How to avoid duplicating tables? -

I need to collect information on the database of dates and dates went into a database to be very scalable and efficient I Database Should I delete the dates table and location dateTicken and dates Planet in different databases? My only reluctance is there are many tables that rely on DateId . Is there a better solution that duplicate tables DateId ?

firebird2.5 - What is the use of firebird.msg in firebird database -



    I'm thinking of using Firebird with my application. I would like to know that the  firebird.msg  is used for the file. Is it an optional or compulsory file to include in your app installer package?       firebird.msg  contains firebird's actual error messages when an error occurs , Firebird only sends the error code and message parameters. The client library then sees the actual error message text in this file.   Without the presence of this file (for firebird 2.5 and earlier its in a folder for  fbclient.dll  (or similar libraries), Firebird 3 and later the same folder In) errormessage will only report that it can not get the  firebird.msg  and error number.   So you do not really need it, but if you need firebird clients or embedded libraries or want and if you want or want a meaningful error message from the firebird, then you should include it.

Due to interchangeable themes in WordPress, I do not know how many widgets will be in WordPress.  and examples of my current theme, based on the available width, I want to display more or fewer columns to fill the row. My idea is to first set the width of the table in the inner width of the wrapping divis, that I can do this with something like    $ ('# objects'). Width ($ ('# Object') .Parent (.) Width ()); Second, it is my goal that to display some columns per line, depending on the width of the row   My questions:    Is my planned way of accomplishing this by sending the width of the table as the parameter of the javasc
