• How can I change the format for outgoing mail headers? For some reason, it expanded to four lines; can not find the ' to: ' line easily.

  After the recent upgrade of the outgoing message header changed completely. He is now a huge block with four lines over bar tools. I can't seem to figure out how to get several 'to' address spaces, and it is also difficult to find the cc: and bcc: a long time ago I remember finding some controls for the headers, but have not been able to find. Would appreciate any help.

• How to find the mode of a string array

  Hey guys,.

  Then I came across this little problem that I thought I could solve easily enough, but it turned quite messy.

  I have this array of strings, and I want to find the most frequent entry in this array. Let's say I have the following table.

  Apple

  Apple

  Kiwi

  Orange

  Apple

  the mode would give me apple. I thought to convert the strings into a number and then find fashion as usual.

  But if the chain is too long, it seems a superelevation of unique number used to represent.

  Any ideas on a clean way to do this?

  This can also work

• Where can I find the line start/run in the box start Windows

  I want to use the Msconfig function but cannot find the start/run line in which to enter.  When I hit the start icon (the microsoft logo), it is not clear.  I'm looking in the wrong place.  If this is the right place where it appears.  If this is not the right place to be looking, where should I look?

  Thank you

  1. you can use the search box instead of running it. It all works the same.

  2 in this case is to know how to restore/enable option run in the right side of the Start Menu:
  Right click on the Start button > properties > at the top, click on Start Menu tab > click Customize > scroll to find command run, put a checkmark in the box > OK

  You check Startmenu. Execution option should be there now.

• How to find the connection line

  Hello

  I have a spatial table with geom type in 2002.

  I have a set of line (for example say it's 5 rows) attach image.

  I need to find the line that is internal linking to these 5 rows. I mean, it's a dividing line has the inside line.

  I am unable to get the inner lines of a border.

  If I have a spatial query table I get limit but I want inner lines.

  Fix is instant for ref.

  Thanks in advance

  This is because CONCAT_LINES does not create a polygon, it only concatenates lines in a new line. But always a line (even if the endpoint and the starting point of this line may be the same).

  It might be a good idea to start reading the Documentation space: content, since it seems that there are some concepts in Oracle Spatial, which are not clear to you. Basically: there is no simple easy feature to create a polygon of a bunch of lines delivered with Oracle, you will need to create one yourself.

  Concat_lines might be a start, however, that allows to create a line, then check the endpoint and the starting point: if they are identical, you can create your polygon. Is they are not the same, you can copy the starting at the end point. You can then change the GTYPE and the Ansdo_elem_info so that the entire element becomes a polygon. With a polygon you can use inside effectively to get the results you want. I don't have access to my environment of development here, so can't help you build something right now. But maybe someone else has something already?

  Oh, and after the fact: do not store your polygons in a temporary table, but change your datamodel and begin to use them properly. Temporary tables will be only complicate things more.

• Find the nearest parallel line and ignore perpendicular line

  Hello
  
  We have two sets of linear facilities. We would like to find the nearest line of the other set of geometry, but preference should be given to the parallel lines as the perpendicular ones more.
  
  I was intending to use the suite response I see in this forum.
  extract the parallel roads
  
  Is another way?
  
  Thank you
  Frédéric

  Frederick,

  It really depends on what you're trying to determine from your data. I noticed that you included 'street' in your tags. Are you trying to link Street - axis facades, utilities or the plots?

  If you use buffering as John suggested, get an account for characteristics how target your buffer interacts with. In some cases (say the intersections of streets) where you will get multiple occurrences, you can compare the angles/slopes to identify the one who more parallel.

  Note that line buffering will produce a Cheeto (right, with well rounded rectangle). The Cheeto may interact with more than 1 target function if your buffer is too big and the characteristics of the target are tip-to-tail connected - and each of these objectives can be parallel to your line. If it's a problem, you can calculate distances to your targets and choose Next. You will probably always compare the slopes to eliminate false positives at intersections.

  In support of geocoding, I once to the streets adjacent plots and tried the above approaches and found that they do not have sufficient accuracy to dead end or corner-bulbs bulbs. Instead, I used the rotation value of the parcel labels (always placed perpendicular to the street) to generate features of research at the intersection of the adjacent streets. These search functions have variable length depending on the type of street. There were still a few false positives due to errors of data (e.g., misguidance label type, incorrect of streets, etc.), but little enough to dump a body to.

• Oracle Spatial function to find the closest channel line according to lat/long

  Hello
  
  Here's my scenario. I have a table that contains the geometries of type line (road network) channels. The line geomteries are of type Ohio state South (SRID 41104) plan.
  I have a requirement - given a lat/long, find the string line that aligns with this lat/long or the nearest set of strings of line at 0.02 miles.
  It is a typical example of an attempt to identify an accident on our road network situation. Accidents reported us in lat/long through the GPS system.
  How can I achieve this through any space function?
  
  Thanks for the help in advance.
  
  Thank you
  L.

  Hello L,

  SELECT
    r.
  FROM
    roadsegments r
  WHERE SDO_NN(r.geometry,
               sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
               'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE';
  

  This will give you the two segments of road nearest you at 0.02 miles. See [url http://docs.oracle.com/cd/E11882_01/appdev.112/e11830/sdo_operat.htm#i78067] documentation on the operator SDO_NN, especially the bit about the use of the index indicator.

• Is there a way to find the length of a line, not a column

  I'm trying to find the length of a particular line in a table... is it possible?
  I don't mean length of the column value... I can get by using LENGTH (COLUMNNAME)
  I'm not average line length, I can get extended calculation or using the trace file.
  Please let me know if there is a function, that allows to calculate or any other solution.
  
  Thank you!

  >
  (1) select avg_row_len from dba_tables
  where table_name = 'abc ';
  I got the length of the average line like 65
  That means 65... It is 65 bytes/KB/MB, or what exactly is 65?
  >
  This means that 65 bytes - see ALL_TABLES in doc database
  http://docs.Oracle.com/CD/B19306_01/server.102/b14237/statviews_2105.htm#i1592091
  >
  (2) also a member of the team of mine use this query:
  SELECT sum (data_length) FROM ALL_TAB_COLUMNS WHERE
  table_name = 'ABC ';
  and divided the result above with the number of rows in this table

  Suppose that gives only the length of the average column type... is not our requirement?
  >
  At best, that would give you the MAXIMUM length that COULD be a line. It will not help at all. For example all columns defined as NUMBER (with any precision or scale) appears in the form of bytes 22 since they can take a lot. And a VARCHAR2 (4000) will be listed as 4000 even if it is NULL or if the average length is 2 bytes.
