Specification

Overview

ODBC defines several Interface conformance levels. In this section you can find which features are supported by the Apache Ignite ODBC driver.

Core Interface Conformance

Feature Supported Comments

Allocate and free all types of handles, by calling SQLAllocHandle and SQLFreeHandle.

YES

Use all forms of the SQLFreeStmt function.

YES

Bind result set columns, by calling SQLBindCol.

YES

Handle dynamic parameters, including arrays of parameters, in the input direction only, by calling SQLBindParameter and SQLNumParams.

YES

Specify a bind offset.

YES

Use the data-at-execution dialog, involving calls to SQLParamData and SQLPutData

YES

Manage cursors and cursor names, by calling SQLCloseCursor, SQLGetCursorName, and SQLSetCursorName.

PARTIALLY

SQLCloseCursor is implemented. Named cursors are not supported by Ignite SQL.

Gain access to the description (metadata) of result sets, by calling SQLColAttribute, SQLDescribeCol, SQLNumResultCols, and SQLRowCount.

YES

Query the data dictionary, by calling the catalog functions SQLColumns, SQLGetTypeInfo, SQLStatistics, and SQLTables.

PARTIALLY

SQLStatistics is not supported.

Manage data sources and connections, by calling SQLConnect, SQLDataSources, SQLDisconnect, and SQLDriverConnect. Obtain information on drivers, no matter which ODBC level they support, by calling SQLDrivers.

YES

Prepare and execute SQL statements, by calling SQLExecDirect, SQLExecute, and SQLPrepare.

YES

Fetch one row of a result set or multiple rows, in the forward direction only, by calling SQLFetch or by calling SQLFetchScroll with the FetchOrientation argument set to SQL_FETCH_NEXT

YES

Obtain an unbound column in parts, by calling SQLGetData.

YES

Obtain current values of all attributes, by calling SQLGetConnectAttr, SQLGetEnvAttr, and SQLGetStmtAttr, and set all attributes to their default values and set certain attributes to non-default values by calling SQLSetConnectAttr, SQLSetEnvAttr, and SQLSetStmtAttr.

PARTIALLY

Not all attributes are supported by now. See table below for details.

Manipulate certain fields of descriptors, by calling SQLCopyDesc, SQLGetDescField, SQLGetDescRec, SQLSetDescField, and SQLSetDescRec.

NO

Obtain diagnostic information, by calling SQLGetDiagField and SQLGetDiagRec.

YES

Detect driver capabilities, by calling SQLGetFunctions and SQLGetInfo. Also, detect the result of any text substitutions made to an SQL statement before it is sent to the data source, by calling SQLNativeSql.

YES

Use the syntax of SQLEndTran to commit a transaction. A Core-level driver need not support true transactions; therefore, the application cannot specify SQL_ROLLBACK nor SQL_AUTOCOMMIT_OFF for the SQL_ATTR_AUTOCOMMIT connection attribute.

YES

Call SQLCancel to cancel the data-at-execution dialog and, in multi-thread environments, to cancel an ODBC function executing in another thread. Core-level interface conformance does not mandate support for asynchronous execution of functions, nor the use of SQLCancel to cancel an ODBC function executing asynchronously. Neither the platform nor the ODBC driver need be multi-thread for the driver to conduct independent activities at the same time. However, in multi-thread environments, the ODBC driver must be thread-safe. Serialization of requests from the application is a conformant way to implement this specification, even though it might create serious performance problems.

NO

Current implementation does not support asynchronous execution. Also, is not supported for data-at-execution.

Obtain the SQL_BEST_ROWID row-identifying column of tables, by calling SQLSpecialColumns.

PARTIALLY

Current implementation always returns empty row set.

Level 1 Interface Conformance

Specify the schema of database tables and views (using two-part naming).

YES

Invoke true asynchronous execution of ODBC functions, where applicable ODBC functions are all synchronous or all asynchronous on a given connection.

NO

Use scrollable cursors, and thereby achieve access to a result set in methods other than forward-only, by calling SQLFetchScroll with the FetchOrientation argument other than SQL_FETCH_NEXT.

NO

Obtain primary keys of tables, by calling SQLPrimaryKeys.

PARTIALLY

Returns empty result set by now.

Use stored procedures, through the ODBC escape sequence for procedure calls, and query the data dictionary regarding stored procedures, by calling SQLProcedureColumns and SQLProcedures.

NO

Connect to a data source by interactively browsing the available servers, by calling SQLBrowseConnect.

NO

Use ODBC functions instead of SQL statements to perform certain database operations: SQLSetPos with SQL_POSITION and SQL_REFRESH.

NO

Gain access to the contents of multiple result sets generated by batches and stored procedures, by calling SQLMoreResults.

YES

Delimit transactions spanning several ODBC functions, with true atomicity and the ability to specify SQL_ROLLBACK in SQLEndTran.

NO

Ignite SQL does not support transactions.

Level 2 Interface Conformance

Feature Supported Comments

Use three-part names of database tables and views.

NO

Ignite SQL does not supports catalogs.

Describe dynamic parameters, by calling SQLDescribeParam.

YES

Use not only input parameters but also output and input/output parameters, and result values of stored procedures.

NO

Ignite SQL does not supports output parameters

Use bookmarks, including retrieving bookmarks, by calling SQLDescribeCol and SQLColAttribute on column number 0; fetching based on a bookmark, by calling SQLFetchScroll with the FetchOrientation argument set to SQL_FETCH_BOOKMARK; and update, delete, and fetch by bookmark operations, by calling SQLBulkOperations with the Operation argument set to SQL_UPDATE_BY_BOOKMARK, SQL_DELETE_BY_BOOKMARK, or SQL_FETCH_BY_BOOKMARK.

NO

Ignite SQL does not supports bookmarks.

Retrieve advanced information about the data dictionary, by calling SQLColumnPrivileges, SQLForeignKeys, and SQLTablePrivileges.

PARTIALLY

SQLForeignKeys implemented, but returns empty result set.

Use ODBC functions instead of SQL statements to perform additional database operations, by calling SQLBulkOperations with SQL_ADD, or SQLSetPos with SQL_DELETE or SQL_UPDATE.

NO

Enable asynchronous execution of ODBC functions for specified individual statements.

NO

Obtain the SQL_ROWVER row-identifying column of tables, by calling SQLSpecialColumns.

PARTIALLY

Implemented by returning an empty row set.

Set the SQL_ATTR_CONCURRENCY statement attribute to at least one value other than SQL_CONCUR_READ_ONLY.

NO

The ability to time out login request and SQL queries (SQL_ATTR_LOGIN_TIMEOUT and SQL_ATTR_QUERY_TIMEOUT).

PARTIALLY

SQL_ATTR_QUERY_TIMEOUT support implemented. SQL_ATTR_LOGIN_TIMEOUT is not implemented yet.

The ability to change the default isolation level; the ability to execute transactions with the "serializable" level of isolation.

NO

Ignite does not support SQL transactions.
