Even if you set Persist Security Info=true OR Persist Security Info=false it won’t show a difference up front. The difference is happening in the background. When Persist Security Info=False, security-sensitive information, such as the password, is not returned as part of the connection if the connection is open or has ever been in an open … Read more
String concatenation is faster in ECMAScript. Here’s a benchmark I created to show you: http://jsben.ch/#/OJ3vo
Currently your application support 100 connections in pool. Here is what conn string will look like if you want to increase it to 200: public static string srConnectionString = “server=localhost;database=mydb;uid=sa;pwd=mypw;Max Pool Size=200;”; You can investigate how many connections with database your application use, by executing sp_who procedure in your database. In most cases default connection … Read more
A bit late on this answer but I think there’s a potential way to do this with a neat little extension method. We can take advantage of the EF convention over configuration plus a few little framework calls. Anyway, the commented code and example usage: extension method class: public static class ConnectionTools { // all … Read more
You need to URL-encode the password portion of the connect string: from urllib.parse import quote_plus from sqlalchemy.engine import create_engine engine = create_engine(“postgres://user:%s@host/database” % quote_plus(“p@ss”)) If you look at the implementation of the class used in SQLAlchemy to represent database connection URLs (in sqlalchemy/engine/url.py), you can see that they use the same method to escape passwords … Read more
You’re missing the following piece of code after the connectionString attribute (assuming that you’re using SQL): providerName=”System.Data.SqlClient”
You could try to connect? For quick (offline) validation, perhaps use DbConnectionStringBuilder to parse it… DbConnectionStringBuilder csb = new DbConnectionStringBuilder(); csb.ConnectionString = “rubb ish”; // throws But to check whether the db exists, you’ll need to try to connect. Simplest if you know the provider, of course: using(SqlConnection conn = new SqlConnection(cs)) { conn.Open(); // … Read more
What you have is a valid ADO.NET connection string – but it’s NOT a valid Entity Framework connection string. The EF connection string would look something like this: <connectionStrings> <add name=”NorthwindEntities” connectionString= “metadata=.\Northwind.csdl|.\Northwind.ssdl|.\Northwind.msl; provider=System.Data.SqlClient; provider connection string="Data Source=SERVER\SQL2000;Initial Catalog=Northwind;Integrated Security=True;MultipleActiveResultSets=False"” providerName=”System.Data.EntityClient” /> </connectionStrings> You’re missing all the metadata= and providerName= elements in your EF connection … Read more
They are synonyms for each other and can be used interchangeably. In .Net, there is a class called SqlConnectionStringBuilder that is very useful for dealing with SQL Server connection strings using type-safe properties to build up parts of the string. This class keeps an internal list of synonyms so it can map from one value … Read more
Use " instead of ” to escape it. web.config is an XML file so you should use XML escaping. connectionString=”Server=dbsrv;User ID=myDbUser;Password=somepass"word” See this forum thread. Update: " should work, but as it doesn’t, have you tried some of the other string escape sequences for .NET? \” and “”? Update 2: Try single quotes for the … Read more
