concatenation

问题 I have a table with 3 Phone columns, I need to run some magic trying to get some records where the phone numbers could match between them, the problem is a Phone number could be on different field between the 2 records. So I think that a canonical string with the 3 phone numbers should allow me to make the comparison, the problem is the canonizing process. Is there a way to do this? I'm adding a snippet to illustrate what I need to do. Table is: ╔═════╦══════════╦══════════╦══════════╗ ║ ID ║

问题 Whats wrong with this HTML / PHP - just doesnt look right - Is there a better way to concatenate html and php variables into url string ??? <a href="movie_night_del.php?id=<?php echo $id ?>&mov=<?php echo $mov ?>">Click here to delete</a> 回答1: I prefer to do it in "more php" way, for example: echo '<a href="movie_night_del.php?id=' . $id . '&mov=' . $mov . '">Click here to delete</a>' //or echo "<a href='movie_night_del.php?id={$id}&mov={$mov}'>Click here to delete</a>" //or escaping " echo "

问题 Im having two jagged lists. First one: List<List<string>> firstList = new List<List<string>>(); { dd ff } { dd ff } { dd ff } Second one: List<List<string>> secondList = new List<List<string>>(); { gg hh } { gg uu } { hh uu } Im having a problem with combining both lists into one like this one: { dd ff gg hh } { dd ff gg uu } { dd ff hh uu } Any Concatenation attempt resulted in just adding secondList elements like another firstList rows like this: { dd ff } { dd ff } { dd ff } { gg hh } { gg

问题 YQL gives out result only in tree view. Is there any way to get the result in Formatted view?? 回答1: Use an XSLT stylesheet to create a formatted view. Here is an example for an RSS feed: <?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="XML" encoding="utf-8" doctype-public="-//W3C//DTD XHTML 1.0 Transitional//EN" doctype-system=http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd indent="yes"/> <xsl

问题 For concatenated SMS messages (in GSM encoding), if extended table symbol (one of these: }{[]|~^\€) is placed at the end of segment, what is correct way to split such message: Leave first byte of symbol (0b) at the end of segment and put second byte to the beginning of next one, and so fill all available bytes of UD (which seems logically correct) OR Move whole symbol bytes to the next segment and leave unused byte at the end? I didn't found any clarification neither in SMPP 3.4 specs or

问题 Ok so a guy at work has a little access database he uses to keep track of things. He has this form that he uses that already queries what he needs and produces the results on a form and that is really all he needs. One thing is that he has duplicates for every record that comes up with a different "Type" as a field "indentifier" (what I call it)...here is an example: ID Name Price Type 1 Prodcut A $10 A1 1 Product A $10 A2 1 Product A $10 A3 2 Product B $12 A1 etc naturally this is supposed

问题 I am a beginner with TensorFlow, I am trying to implement a function that takes a batch as input. It has to slice this batch into several ones, apply some operations on them, then concatenate them to build a new tensor to return. Through my readings, I found there are some implemented function like input_slice_producer and batch_join but I didn't get to work with them. I attached what I've found as solution below, but it's kinda slow, not proper and incapable of detecting the current size of

问题 I have an xml file that looks like this: <args> <sometag value="abc" /> <anothertag value="def" /> <atag value="blah" /> </args> keep in mind that tag names within args could be named anything (I don't know ahead of time) Now i have this xml file stored in a variable called $data which I loaded using a document() call in the xslt stylesheet (its not the backing data for the xslt file) I want to take that data and produce the following output: sometag=abc&anothertag=def&atag=blah so (a very

问题 I have two big numpy 2D arrays. One shape is X1 (1877055, 1299), another is X2 (1877055, 1445). I then use X = np.hstack((X1, X2)) to concatenate the two arrays into a bigger array. However, the program doesn't run and exit with code -9. It didn't show any error message. What is the problem? How can I concatenate such two big numpy 2D arrays? 回答1: Unless there's something wrong with your NumPy build or your OS (both of which are unlikely), this is almost certainly a memory error. For example,

问题 I have two tables as follows: TABLE A TABLE B StuID | actid FacID | actid 3 12 98 17 5 17 54 21 I want to list the name of everyone, both students and faculty, who participate in activity 17. Is there anyway I can get a result as below: id | actid 98 17 5 17 WITHOUT creating a new table (by just using nesting of expressions or derived relations) ? A JOIN on the actid would give something like: StuID | FacID | actid 5 98 17 I guess I need a form of concatenation?? 回答1: select * from table_a
