Database types
Starcounter supports most of the .NET CLR primitive types.
BooleanByteDoubleInt16Int32Int64SByteSingleUInt16UInt32UInt64
Starcounter saves and returns all
DateTime values in UTC.[Database]
public abstract class Item
{
public abstract DateTime Value { get; set; }
public void TestDateTimeValues()
{
var v = new DateTime(DateTime.Now.Ticks, DateTimeKind.Local);
// The value and the kind are converted into UTC when the CLR type
// is converted to a database type, which happens here:
this.Value = v;
var kindAfter = this.Value.Kind; // System.DateTimeKind.Utc
}
}
Starcounter does not yet support the
DateTimeOffset data type.The
Decimal values are stored as a 64-bit integer and has a precision of six decimals and a range between -4398046511103.999999 and 4398046511104.999999. Trying to store a Decimal value with higher precision or outside of the specified range will result in the following exception: ScErrCLRDecToX6DecRangeError (SCERR4246). In those cases, Double can be used if the data loss is acceptable.The string data type can store data up to 1 MiB of encoded text. Thus, all strings with a length of less than 270600 will fit into the string data type. Strings with more than 270600 characters might fit depending on string content.
Starcounter does not yet support non-nullable strings.
The
Binary data type is a Starcounter-defined datatype used to store binary data in the database. The maximum size of a binary field is 1 MiB.Starcounter only supports nullable binary properties.
public abstract class Item
{
// This defines a nullable binary property.
// It is supported by Starcounter.
public abstract Binary? NonNullBinary { get; set; }
// This defines a not nullable binary property.
// It is not yet supported by Starcounter.
public abstract Binary NonNullBinary { get; set; }
}
