• How to sanity check a date in java

  - by Bloodboiler

  I find it curious that the most obvious way to create Date objects in Java has been deprecated and appears to have been "substituted" with not so obvious to use lenient calendar. So... How do you check that a date given as a combination of day, month and year is a valid date? For instance a date 2008-02-31 (as in yyyy-mm-dd) would be invalid date.

• Combining the UNIQUE and CHECK constraints

  - by Bobby

  I have a table with columns a b and c, and if c is false then I only want to allow insertions if columns a and b are unique, but if c is true then a and b do not need to be unique. Example: There can only be one (foo, bar, false) in the table, but no limit on how many (foo, bar, true) there can be. I tried something like CONSTRAINT blah UNIQUE (a,b) AND CHECK (C is TRUE) but I can't figure out the correct syntax.

• Lighttpd check request headers in configuration

  - by Mike Hayes

  Hi I was wondering if it was possible in the configuration of Lighttpd to read request headers, I've searched and searched.. apparently it's not possible. For example, conditional configuration based upon IP address: $HTTP["remoteip"] == "0.0.0.0" { // Do something } Is there something similar to check headers, for example: $HTTP["X-Some-Header"] == "Value" { // Do something } I'm thinking there isn't but thought I would post here as a last resort. Google didn't help much, and Lighttpd documentation would suggest this is not possible. Thanks Mike

• Disable TSQL script check?

  - by grady

  Hi, lets say I have a script like that: if(some condition) begin select somecolumn from sometable end Lets say, that "somecolumn" does not exist and the condition is not true, which means the select is NOT executed. Even though the select would not be executed, the script is not valid, Management Studio complains about the missing column "somecolumn". Question: Can I somehow disable this sort of check so that the script is executed and since the if is not true, it will never notice that the column is missing? Thanks :-)
