You can find the stored definition with the below (remember to adjust the column and table name to find to be ones relevant to your environment!) SELECT object_definition(default_object_id) AS definition FROM sys.columns WHERE name=”colname” AND object_id = object_id(‘dbo.tablename’)
You can use this code to do it automatically: DECLARE @tableName VARCHAR(MAX) = ‘<MYTABLENAME>’ DECLARE @columnName VARCHAR(MAX) = ‘<MYCOLUMNAME>’ DECLARE @ConstraintName nvarchar(200) SELECT @ConstraintName = Name FROM SYS.DEFAULT_CONSTRAINTS WHERE PARENT_OBJECT_ID = OBJECT_ID(@tableName) AND PARENT_COLUMN_ID = ( SELECT column_id FROM sys.columns WHERE NAME = @columnName AND object_id = OBJECT_ID(@tableName)) IF @ConstraintName IS NOT NULL EXEC(‘ALTER TABLE … Read more
The default value of int is 0 and that is the value it will have in both JavaSE and JavaEE unless it was assigned with another value. You can’t have an uninitialized int class member in Java (or any other primitive). In your example you show the int is a class member, in the other … Read more
Try this @Target(ElementType.TYPE) @Retention(RetentionPolicy.RUNTIME) public @interface SomeInterface { Class bar() default void.class; } It does not require a new class and it is already a keyword in Java that means nothing.
It’s a new feature in Java 8 which allows an interface to provide an implementation. Described in Java 8 JLS-13.5.6. Interface Method Declarations which reads (in part) Adding a default method, or changing a method from abstract to default, does not break compatibility with pre-existing binaries, but may cause an IncompatibleClassChangeError if a pre-existing binary … Read more

Interesting. I had more luck sending IAC WILL ECHO IAC WILL SUPPRESS_GO_AHEAD IAC WONT LINEMODE 255 251 1 255 251 3 255 252 34 The IAC WONT LINEMODE seems to be redundant: my telnet client seems to get to the right state without it, but I left it in for completeness.
One way to do it SELECT IFNULL(MIN(`file`), ‘default.webm’) `file` FROM `show`, `schedule` WHERE `channel` = 1 AND `start_time` <= UNIX_TIMESTAMP() AND `start_time` > UNIX_TIMESTAMP()-1800 AND `show`.`id` = `schedule`.`file` ORDER BY `start_time` DESC LIMIT 1 Since you return only one row, you can use an aggregate function, in that case MIN(), that ensures that you’ll get … Read more
You can get the precision before you change it, with std::ios_base::precision and then use that to change it back later. You can see this in action with: #include <ios> #include <iostream> #include <iomanip> int main (void) { double d = 3.141592653589; std::streamsize ss = std::cout.precision(); std::cout << “Initial precision = ” << ss << ‘\n’; … Read more
The reason that you have to uncomment the default is that your function says that it returns a String, but if you only have case labels defined for A and B then the function will not return a value if you pass in anything else. Java requires that all functions that state that they return … Read more
