php - A logical problem with two tables -

- April 15, 2012

Hey guys, I have made a list for fixtures.

mysql_query ("<"> <"date selected by date" .TBL_FIXTURES. "Where compname = '$ comp_name' group" date "); $ I = 1; $ D = "Start"; While ($ line = mysql_fetch_assoc ($ result)) {$ odate = $ line ['date']; $ Date = date ("FJY", $ line ['date']); Echo "& lt; p & gt; Stability $ i - $ d to $ date & lt; / p & gt;"; }

As you can see from the query, the date is displayed from the fixtures table. The way my system works is that when "steady" is played, it is removed from this table so that when the whole round fixtures are completed, there is no date for that round in this table. Was there. They will be in the second table.

Anyway, if I can run another query for the dates at the same time, and there is no date in the results table, then can I display the date from the fixtures table?

  "SELECT * FROM" .TBL_CONF_RESULTS "Where compiled = '$ _GET [id]' and amp; type2 = '2' order date"

this will be the second query!

Edit from here ...

Can any one select a date from two tables and then use only one if there are matches then my query Use the lines of dates to fill (grouped by)? Is this possible?

It looks as if you want two result set union, similar to the following:

< Pre>

 SELECT f.date to tbl_fixtures f where f.compname = '$ comp_name' select the union from r.date to tbl_conf_results r where r.compid = '$ _get [id]' and r.type2 = '2' Select the group's date  and the rows from r.date which are not already in the result set (at least this T-SQL). Apparently this may not be well, but there are many blogs on it (Search: Union T-SQL).

windows - Heroku throws SQLITE3 Read only exception -

September 15, 2015








    After I deploy the app to Heroku, I have to run migration scripts and get this error message    ... ITES \ padrino \ prophetmargin & gt; Heroku Rack AR: Rack mutated! SQLite3 :: ReadOnlyException: only one try to write database to read: CREATE TABLE "schema_migrations" ( "version" varchar (255) NOT NULL) /disk1/home/slugs/215264_925fd2c_65a3/mnt/.bundle/gems/gems/ padrino-core- is 0.9.11 / lib / padrino-core / cli / rake.rb: 9: in `init '    how can this be? I also tried to run Heroku dbpush SQLite: //db/my-db.db and that did not work      Horoku sqlite3 but using postgres does not do. I'm not sure why you are receiving this error, however, as I have used sqlite3 in development and when pushing it into its travel, they do some magic which migrates to postgrads.   I'm absolutely sure how Heroku does 'backwash' this database but it seems that this is happening to you because it's the SQLite db file which is obviously due to Heroku's

lex - Building a lexical Analyzer in Java -



-



September 15, 2015








    I am currently learning lexical analysis in compiler design. To know how a lexical analyzer actually works, I am trying to build myself. I am planning to make it in Java   The input to the lexical analyzer is a .tex file that is of the following format.    \ section {script} {intro} \ section {Scope} arbitrary text \ section {relevance} uncontrolled text \ subdivision (profit) arbitrary text \ subsubsection {in real life} \ subdivision {Ingredient} \ end {document}    The output of the lecture may be a table of contents with a page number in another file.    1 Introduction 1 1.1 Scope 1 1.2 Relevance 2 1.2.1 Benefits 2 1.2.1.1 Real life 2 1.2.2 loss 3 I hope that This problem is within the scope of  Language Analysis     Read the .exe file and check '\' and continue to check whether it is actually on search In the sectioning command is set to indicate whether or not a flag variable is the type of sectioning.   I hope the above approach will work for the construction of Lexa

python - rename keys in a dictionary -



-



February 15, 2015








    I want to change the names of keys in a dictionary which are ints, and I need them so that the inputs with key zero They can sort correctly.   For example, my keys are like this:    '1', '101', '11'    and I may need them:    '001', '101', '011'    What is doing, but I know that there is a better way    tmpDict = {} in the ADC for the old: t MpDict ['% 04d'% int (olden)] = addict [oldkey] New controlled = tmpDict       You are going wrong about this if you want to draw entries on a line in a specific way, then you have to sort on the extraction.    for sorted (D, key = int): print '% s:% R'% (k, d [k])   < / Div>
