This warning is telling you there’s a conflict in your constraints. Reduce the priority of the height constraint to 999 and it will go away. Tested it in your Github project and worked perfectly.
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
You need to first change the constraint and then animate the update. This should be in the superview. self.nameInputConstraint.constant = 8 Swift 2 UIView.animateWithDuration(0.5) { self.view.layoutIfNeeded() } Swift 3, 4, 5 UIView.animate(withDuration: 0.5) { self.view.layoutIfNeeded() }
Nope, I’m afraid not. The only things you can do with constraints are: where T : class – T must be a reference type where T : struct – T must be a non-nullable value type where T : SomeClass – T must be SomeClass or derive from it where T : ISomeInterface – T … Read more
Many solvers (including IPOPT) will hand you back the value of the variables at solver termination, even if the problem was found infeasible. At that point, you do have some options. There is contributed code in pyomo.util.infeasible that might help you out. https://github.com/Pyomo/pyomo/blob/master/pyomo/util/infeasible.py Usage: from pyomo.util.infeasible import log_infeasible_constraints … SolverFactory(‘your_solver’).solve(model) … log_infeasible_constraints(model)
No, MySQL is doing the right thing, according to the SQL-99 specification. https://mariadb.com/kb/en/sql-99/constraint_type-unique-constraint/ A UNIQUE Constraint makes it impossible to COMMIT any operation that would cause the unique key to contain any non-null duplicate values. (Multiple null values are allowed, since the null value is never equal to anything, even another null value.) If you … Read more
It’s not possible. I’d like to see “static interfaces” to handle this, but don’t expect them any time soon… Alternatives: Specify a delegate to act as a factory for T Specify another interface to act as a factory for T Specify an interface on T itself for initialization (and add a constraint so that T … Read more
Fairly easy to do with Auto-Layout only… no code required. The key is to use a “content view” to hold the elements, and a greater-than-or-equal constraint between your “bottom” element and your “footer” view. In this image, yellow is the main view, green is the scroll view, blue is the content view, the labels are … Read more
Use the information_schema.table_constraints table to get the names of the constraints defined on each table: select * from information_schema.table_constraints where constraint_schema=”YOUR_DB” Use the information_schema.key_column_usage table to get the fields in each one of those constraints: select * from information_schema.key_column_usage where constraint_schema=”YOUR_DB” If instead you are talking about foreign key constraints, use information_schema.referential_constraints: select * from … Read more
You can implement something similar to them with triggers, but MySQL itself (before version 8.0.16) doesn’t support CHECK constraints. Don’t worry though, it’ll let you define them and just silently ignore them!
