This module contains buffers intended to be bound to ODBC statement handles.
Introduction to odbc-api (documentation only)
Provides basic abstraction over valid (i.e. allocated ODBC handles).
Passing parameters to statement
Structs
New type wrapping u8 and binding as SQL_BIT.
Describes the type and attributes of a column.
Can be used to execute a statement with bulk array paramters. Contrary to its name any statement
with parameters can be executed, not only INSERT however inserting large amounts of data in
batches is the primary intended usecase.
The connection handle references storage of all information about the connection to the data source, including status, transaction state, and error information.
Cursors are used to process and iterate the result sets returned by executing queries. Created
by either a prepared query or direct execution. Usually utilized through the crate::Cursor
trait.
An individual row of an result set. See crate::Cursor::next_row.
Holds name and description of a datasource
Struct holding information available on a driver. Can be obtained via Environment::drivers.
An ODBC 3.8 environment.
Wraps a type T together with an additional indicator. This way the type gains a Null representation, those memory layout is compatible with ODBC.
A preallocated SQL statement handle intended for sequential execution of different queries. See
crate::Connection::preallocate.
A prepared query. Prepared queries are useful if the similar queries should executed more than once.
A row set cursor iterates in blocks over row sets, filling them in buffers, instead of iterating the result set row by row. This is usually much faster.
Statement handle which also takes ownership of Connection
Error indicating a failed allocation for a column buffer
16-bit wide string slice with undefined encoding.
An owned, mutable 16-bit wide string with undefined encoding.
Enums
Enumeration over valid SQL Data Types supported by ODBC
Specifies how the driver and driver manager complete the incoming connection string. See
crate::Environment::driver_connect.
Error type used to indicate a low level ODBC call returned with SQL_ERROR.
Indication of whether a column is nullable or not.
Traits
You can obtain a mutable slice of a column buffer which allows you to change its contents.
Cursors are used to process and iterate the result sets returned by executing queries.
An instance can be consumed and to create a parameter which can be bound to a statement during execution.
Implementers of this trait can be bound to a statement through a
self::ParameterCollectionRef.
SQL Parameters used to execute a query.
Implementers of this trait can be used as individual parameters of in a tuple of parameter references. This includes input parameters, output or in/out parameters.
Provides Metadata of the resulting the result set. Implemented by Cursor types and prepared
queries. Fetching metadata from a prepared query might be expensive (driver dependent), so your
application should fetch the Metadata it requires from the Cursor if possible.
A Row set buffer binds row, or column wise buffers to a cursor in order to fill them with row sets with each call to fetch.
Functions
You can use this method to escape a password so it is suitable to be appended to an ODBC
connection string as the value for the PWD attribute. This method is only of interest for
application in need to create their own connection strings.
