Crate odbc_sys [−] [src]

ODBC types those representation is compatible with the ODBC C API.

This layer has not been created using automatic code generation. It is incomplete, i.e. it does not contain every symbol or constant defined in the ODBC C headers. Symbols which are deprecated since ODBC 3 have been left out intentionally. While some extra type safety has been added by grouping some of C's #define constants into enum-types it mostly offers the same power (all) and safety guarantess(none) as the wrapped C-API. ODBC 4.0 is still under development by Microsoft, so these symbols are deactivated by default in the cargo.toml

Functions

SQLAllocHandle ^⚠	Allocates an environment, connection, statement, or descriptor handle.
SQLBindCol ^⚠	Binds application data bufferst to columns in the result set.
SQLBindParameter ^⚠	Binds a buffer to a parameter marker in an SQL statement
SQLCloseCursor ^⚠	Closes a cursor that has been opened on a statement and discards pending results.
SQLConnect ^⚠	SQLConnect establishes connections to a driver and a data source. The connection handle references storage of all information about the connection to the data source, including status, transaction state, and error information.
SQLDataSources ^⚠	Returns information about a data source. This function is implemented only by the Driver Manager.
SQLDescribeCol ^⚠	Returns the result descriptor for one column in the result set — column name, type, column size, decimal digits, and nullability.
SQLDisconnect ^⚠	Closes the connection associated with a specific connection handle.
SQLDriverConnect ^⚠	An alternative to `SQLConnect`. It supports data sources that require more connection information than the three arguments in `SQLConnect`, dialog boxes to prompt the user for all connection information, and data sources that are not defined in the system information
SQLDrivers ^⚠	Lists driver descriptions and driver attribute keywords. This function is implemented only by the Driver Manager.
SQLExecDirect ^⚠	Executes a preparable statement, using the current values of the parameter marker variables if any parameters exist in the statement. This is the fastest way to submit an SQL statement for one-time execution
SQLExecute ^⚠	Executes a prepared statement, using the current values of the parameter marker variables if any paramater markers exis in the statement.
SQLFetch ^⚠	SQLFetch fetches the next rowset of data from the result set and returns data for all bound columns.
SQLFreeHandle ^⚠	Frees resources associated with a specific environment, connection, statement, or descriptor handle.
SQLFreeStmt ^⚠	Stops processing associated with a specific statement, closes any open cursors associated with the statement, discards pending results, or, optionally, frees all resources associated with the statement handle.
SQLGetData ^⚠
SQLGetDiagRec ^⚠	Return the current values of multiple fields of a diagnostic record that contains eror, warning, and status information.
SQLGetInfo ^⚠	Returns general information about the driver and data source associated with a connection
SQLNumResultCols ^⚠	Returns the number of columns in a result set
SQLPrepare ^⚠	Compiles the statement and generates an access plan.
SQLSetEnvAttr ^⚠	Sets attributes that govern aspects of environments
SQLTables ^⚠	Returns the list of table, catalog, or schema names, and table types, stored in a specific data source. The driver returns the information as a result set
