escaping

When I am trying to execute INSERT statement in oracle, I got SQL Error: ORA-00917: missing comma error because there is a value as Alex's Tea Factory in my INSERT statement. How could I escape ' ?

For the moment I am just attempting to log which key is pressed. However the Escape key is never detected. @HostListener('document:keypress', ['$event']) handleKeyboardEvent(event: KeyboardEvent) { console.log(event); let x = event.keyCode; if (x === 27) { console.log('Escape!'); } } Try it with a keydown or keyup event to capture the Esc key.

We all know that we should use prepared statements or the appropriate replacement/formatting rules in order to prevent sql injection in our applications.

See note following the table. \\ A backslash ( \ ) character. \% A % character. \

I have a project, in which some JavaScript var is evaluated. Because the string needs to be escaped (single quotes only), I have written the exact same code in a test function. I have the following bit of pretty simple JavaScript code: function testEscape() { var strResult = ""; var strInputString = "fsdsd'4565sd"; // Here, the string needs to be escaped for single quotes for the eval // to work as is. The following does NOT work! Help! strInputString.replace(/'/g, "''"); var strTest = "strResult = '" + strInputString + "';"; eval(strTest); alert(strResult); } And I want to alert it, saying:

Is there any straightforward way of telling the whole WPF application to react to Escape key presses by attempting to close the currently focused widow? It is not a great bother to manually setup the command- and input bindings but I wonder if repeating this XAML in all windows is the most elegant approach? <Window.CommandBindings> <CommandBinding Command="Close" Executed="CommandBinding_Executed" /> </Window.CommandBindings> <Window.InputBindings> <KeyBinding Key="Escape" Command="Close" /> </Window.InputBindings> Any constructive suggestions welcome! All I can suggest to improve on that is

I am trying to open an SQL data connection using a PowerShell script and my password contains a $ sign: $cn = new-object system.data.SqlClient.SqlConnection("Data Source=DBNAME;Initial Catalog=Catagory;User ID=User;Password=pass$word;") When I try to open a connection it says: Login failed Shankar R10N Escape it by using backtick (`) as an escape character for the dollar sign ($).
