Update of .NET Provider for OLEDB. Support of schemas implemented.

Leave a comment

We continue to develop our .NET Provider for OLEDB. In the new build (#1434), we have implemented the methods to obtain database metadata:

  • OleDbConnection.GetOleDbSchemaTable
  • OleDbConnection.GetSchema

GetOleDbSchemaTable

Supported schemas:

  • SchemaGuids
  • DbInfoKeywords
  • DbInfoLiterals
  • All schemas of the OLEDB Provider

Distinctions compared to standard OLEDB.NET Provider:

  • The SchemaGuids schema describes all schemas including SchemaGuids, DbInfoKeywords and DbInfoLiterals.
  • The SchemaGuids schema supports restrictions for the Schema column.

GetSchema

Supported schemas:

  • MetaDataCollections
  • Restrictions
  • DataTypes
  • ReservedWords
  • DataSourceInformation
  • CharacterSets
  • Collations
  • Tables
  • Views
  • Columns
  • Procedures
  • ProcedureParameters
  • ProcedureColumns
  • Indexes

Distinctions compared to standard OLEDB.NET Provider:

  • The MetaDataCollections schema supports restrictions for the column CollectionName.
  • The Restrictions schema supports restrictions for the columns CollectionName and RestrictionName.
  • More accurate population of the DataSourceInformation schema.
  • More accurate population of the Restrictions schema.

Implementation peculiarities

  • Caching of data from its own schemas (SchemaGuids, DbInfoKeywords, DbInfoLiterals, …).
  • Coherence of information from metadata schemas with the descriptions of the resulting rowset columns and command parameters (ensured by IBProvider).
  • Different algorithms of metadata loading for Interbase and Firebird. Including – our provider takes into account the version of the server and the version of database ODS (ensured by IBProvider).
  • Caching of OLEDB metadata schemas is carried out on the IBProvider level (see a property «schema_cache»).

Other changes

  • The OleDbSchemaGuid class added with the lists of known OLEDB schema identifiers.
  • The OleDbSchemaRestriction class added with the lists of restriction indexes for known OLEDB schemas.
  • The OleDbLiteral class added.
  • The OleDbMetaDataCollectionNames class added.
  • The number of tests and debug structures ensuring the correct work of components increased.

New examples

If you are interested in working with stored procedures grouped into PACKAGE, please take a look at the new example for our .NET Provider:

    Firebird driver

    A half year before we product first release of LCPI ADO.NET Data Provider for OLEDB, which became powerful alternative of standard .Net OLE DB Provider and provide advanced opportunities for all Firebird and Interbase users in .Net Framework:

    • Automatic generation of command parameters which you do not need to enter manually anymore;
    • Named and unnamed parameters, also IN, OUT and IN-OUT parameters;
    • Connection pooling and SQL statement pooling which let your code run even faster;
    • Nested («nested_trans=true») and distributed (TransactionScope, EnlistTransaction) transactions;
    • All data types, including GUID, TIME (Dialect 3), DATE (Dialect 3) and multidimensional arrays;
    • The MARS technology which enables working simultaneously with several active DataReader objects;
    • And hey, ExecuteScalar now really loads one value only, not the entire record
    • Multiple parameter-containing commands in one statement (SQL scripts);

    Up to this day LCPI ADO.NET Data Provider for OLEDB was available only in professional version of IBProvider but now you can download it on the download page together with first release of IBProvider in the new year:
