Ad-hoc retreival of data from SQL Server varbinary column -

-

i retreive binary data varbinary(max) column in sql server database debugging purposes.

what easiest way data local binary file, preferably without having write throw-away console application?

i have tried using sql server management studio (with "results file" option) outputs hex encoded binary string file, rather raw binary data.

i've found this solution bcp command (run command prompt):

c:\temp>bcp "select myvarbinarycol mytable id = 1234" queryout "c:\filename.pdf" -s mysqlserver\myinstance -t  enter file storage type of field filedata [varbinary(max)]: enter prefix-length of field filedata [8]: 0 enter length of field filedata [0]: enter field terminator [none]:  want save format information in file? [y/n] n  starting copy...  1 rows copied. network packet size (bytes): 4096 clock time (ms.) total : 15 average : (66.67 rows per sec.)

i used -t option use windows authentication connect db. if use password auth, you'll need use -u , -p switches specify username , password.

but linqpad suggestion in robb sadler's answer , somehow prefer it.

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
