Accuracer ODBC Driver

The Accuracer ODBC Driver provides read/write access to Accuracer database in accordance with Level1 interface conformance of ODBC v.2 specification with some additional Level2 features.

Starting with v.2.00 Accuracer ODBC Driver works in client-server mode as well as in file-server mode it supported before.

In file-server mode Accuracer ODBC Driver requires a local or network path to the database file. When you update or insert new data, be sure that the database you work with is not opened in exclusive mode by another application (for example, by AccuracerDatabaseServer utility).

In client-server mode you must specify connection parameters (such as network address of the server). Be sure that the AccuracerDatabaseServer utility or your own server application was started and configured properly to work with the target database.

The Accuracer ODBC Driver exhibits Level1 interface conformance. The features in the Core level also correspond to the features defined in the ISO CLI specification and to the nonoptional features defined in the X/Open CLI specification. The Accuracer ODBC Driver allows the application to do all of the following:

• Allocate and free all types of handles, by calling SQLAllocConnect, SQLAllocEnv, SQLAllocStmt, and SQLFreeConnect, SQLFreeEnv, SQLFreeStmt.
• Use all forms of the SQLFreeStmt function.
• Gain access to the description (metadata) of result sets, by calling SQLColAttributes, SQLDescribeCol, SQLNumResultCols, and SQLRowCount.
• Query the data dictionary, by calling the catalog functions SQLGetTypeInfo, SQLTables, and SQLColumns.
• Establish connections, by calling SQLConnect and SQLDriverConnect.
• Handle dynamic parameters, including arrays of parameters, in the input direction only, by calling SQLBindParameter.
• Prepare and execute SQL statements by calling SQLPrepare and SQLExecute. Execute SQL statements, by calling SQLExecDirect. All these functions support SQL template and insert values binding by SQLBindParameter in it.
• Bind result set columns using row-wise binding as well as column-wise binding, by calling SQLBindCol.
• Fetch one binding row of a result set data and scroll the cursor to the next row, in the forward direction only, by calling SQLFetch or by calling SQLExtendedFetch.
• Use scrollable cursors, and thereby achieve access to a result set in methods other than forward-only, by calling SQLExtendedFetch with the following FetchOrientation arguments: SQL_FETCH_NEXT, SQL_FETCH_FIRST, SQL_FETCH_LAST, SQL_FETCH_PRIOR, SQL_FETCH_ABSOLUTE, SQL_FETCH_RELATIVE.
• Fetch one row of a result set or multiple rows using block cursors, by calling SQLExtendedFetch.
• Obtain an unbound column in parts, by calling SQLGetData.
• Obtain current values of connection and statement attributes, by calling SQLGetConnectOption and SQLGetStmtOption, and set all attributes to their default values and set certain attributes to nondefault values by calling SQLSetConnectOption and SQLSetStmtOption.
• Detect driver capabilities, by calling SQLGetFunctions and SQLGetInfo.

• Multipart name emulation is released in SQLGetInfo, SQLTables, SQLColumns, SQLPrepare, SQLExecute, SQLExecDirect to allow some application to work with driver. (Level1 and Level2 Interface Conformance)
• SQL_DESC_NUM_PREC_RADIX, SQL_DESC_NULLABLE attributes in SQLColAttributes (ODBC v.3 Specification)

The Accuracer ODBC Driver supports ODBC v.2 functions only. Nevertheless you can use it even if your application uses ODBC v.3 functions because the Driver Manager (a Windows dll(s)) maps ODBC v.3 functions to ODBC v.2 functions.

Some features of Accuracer functionality are not available in the Accuracer ODBC Driver due to ODBC standard restrictions. Despite this fact the driver is fully functional and allows almost all database operations, some functions are partially implemented yet and others have some peculiarities. Read Accuracer ODBC Driver White Paper to learn about the Driver features. Also you can find there some recommendations on how to work with the driver.

To learn about Accuracer database format read Accuracer Specification.
