sql server - Does a Full-Text Index work well for columns with embedded code values -


using sql server 2012, i've got table has several hundred-thousand rows, , grow.

in table, i've got nvarchar(30) field contains medical record number (mrn) values. these values can alphanumeric value, not words.

for example,

dr-345687 34568523 *45612345;t

my application allows end user enter value, '456' in search field. application need return 3 of example records.

currently, i'm using entity framework 5.0, , asking field.contains('456') type of search.

this takes 3-5 seconds return since appears table search.

my question is: creating full text index on column performance? haven't tried yet because copy of database have lots of data in in qa trials.

looking @ documentation full text indexes appears optimized around separate words in field value, hesitant take performance hit create index without knowing how affect query performance.

ef won't use t-sql keywords needed access sql server full text index (http://msdn.microsoft.com/en-us/library/ms142571.aspx#queries) solution won't fly without more work.

i think have create sproc data using fti , have ef call this. have similar issue , interested know results.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).

javascript - Clean way to programmatically use CSS transitions from JS? -

as title implies, there proper way set initial css properties (or class) , tell browser transition these value? for example ( fiddle ): var el = document.queryselector('div'), st = el.style; st.opacity = 0; st.transition = 'opacity 2s'; st.opacity = 1; this not animate opacity of element in chrome 29/firefox 23. because ( source ): [...] you’ll find if apply both sets of properties, 1 after other, browser tries optimize property changes, ignoring initial properties , preventing transition. behind scenes, browsers batch property changes before painting which, while speeding rendering, can have adverse affects. the solution force redraw between applying 2 sets of properties. simple method of doing accessing dom element’s offsetheight property [...] in fact, hack work in current chrome/firefox versions. updated code ( fiddle - click run after opening fiddle run animation again): var el = document.queryselector('div'...
