Connecting from Code
The CData ADO.NET Provider for CockroachDB implements a standard DbConnection object in CockroachDBConnection. You can also use the CockroachDBConnectionStringBuilder to programmatically build, parse, and rebuild connection strings.
Creating Connection Objects
See Establishing a Connection for guides to defining the connection string and authenticating. Below is a typical invocation to create CockroachDBConnection objects.
C#
using (CockroachDBConnection connection =
new CockroachDBConnection("User=root;Password=root;Database=system;Server=localhost;Port=26257"))
{
connection.Open();
}
VB.NET
Using connection As New CockroachDBConnection("User=root;Password=root;Database=system;Server=localhost;Port=26257")
connection.Open
End Using
Using CockroachDBConnectionStringBuilder
The following code example shows how to use an ADO.NET connection string builder to parse a connection string.
C#
CockroachDBConnectionStringBuilder builder =
new CockroachDBConnectionStringBuilder("User=root;Password=root;Database=system;Server=localhost;Port=26257");
//Pass the connection string builder an existing connection string, and you can get and set any of the elements as strongly typed properties.
builder.ConnectionString = "User=root;Password=root;Database=system;Server=localhost;Port=26257";
//Now that the connection string has been parsed,
// you can work with individual items:
builder.MyString = "new property";
builder.MyBoolean = true;
// You can refer to connection keys using strings,
// as well.
builder["Logfile"] = "test.log";
builder["Verbosity"] = 5;
VB.NET
Dim builder As CockroachDBConnectionStringBuilder = New CockroachDBConnectionStringBuilder("User=root;Password=root;Database=system;Server=localhost;Port=26257")
'Pass the connection string builder an existing connection string, and you can get and set any of the elements using strongly typed properties.
builder.ConnectionString = User=root;Password=root;Database=system;Server=localhost;Port=26257"
'Now that the connection string has been parsed,
' you can work with individual items:
builder.MyString = "new property"
builder.MyBoolean = True
' You can refer to connection keys using strings,
' as well.
builder("Logfile") = "test.log"
builder("Verbosity") = 5
