Adb ODBC Provider

You can use these databases (among others) in your ETL:

Data Type Mappings

This section lists which database types map to or from which .NET types when querying an ODBC server and working with its database parameters. The listed .NET types below are fully supported by the dataflow.

Note

Mappings tagged with AdbColumnSchema below depend on whether or not an AdbColumnSchema is supplied to SetMappedType(AdbParameter, Type, AdbColumnSchema, ParameterDirection). Of the out of box workers, this is only supplied by AdbInsertTarget<TInputError>.

Provider-Independent .NET Types

.NET Type Display Name DbType (or OdbcType) enum SQL Type (uses SQL Server as example)
System.Boolean, System.Boolean? Boolean bit
System.Byte, System.Byte? Byte tinyint
System.Byte[] Binary binary(7), image, varbinary(10), varbinary(max)
System.DateTime, System.DateTime? OdbcType.DateTime datetime. Without AdbColumnSchema also: date, datetime2, smalldatetime.
System.DateTime, System.DateTime? OdbcType.Date, OdbcType.DateTime, OdbcType.SmallDateTime With AAdbColumnSchema: date, datetime2, smalldatetime
System.Decimal, System.Decimal? Decimal decimal(38,0), money, numeric(10,2), smallmoney
System.Double, System.Double? Double float
System.Guid, System.Guid? Guid uniqueidentifier
System.Int16, System.Int16? Int16 smallint
System.Int32, System.Int32? Int32 int, integer
System.Int64, System.Int64? Int64 bigint
System.Single, System.Single? Single real
System.String String char(32), nchar(32), ntext, nvarchar(max), text, varchar(max)

Provider-Specific .NET Types

This provider does not map any provider-specific .NET types. It does however use OdbcType when mapping System.DateTime above.

Parameters

Use positional parameters of the format ?. You can use GetPlaceholder(String) to get the placeholder in a portable manner.

Adb Information

The Adb Information example program dumps the below information with this provider querying a MariaDB server. See that example for more information.

Note

The values below will be different if querying a different type of server.

=== AdbConnection.SchemaInformationCollection ===
Note: The metadata schemas can be retrieved with AdbConnection.GetSchema().
The returned information is provided from the .NET provider as-is. Some collections
can be inaccurate, and different values can also be needed for different purposes,
which is why database specific actionETL providers can be created that replace
individual values with the desired ones. See the vendor provider documentation for
details on the returned information.
