MySqlConnector A registry of known authentication plugins. Registers the specified authentication plugin. The name of this plugin must be unique. The authentication plugin. The primary interface implemented by an authentication plugin. The authentication plugin name. Creates the authentication response. The client's password. The authentication data supplied by the server; this is the auth method data from the Authentication Method Switch Request Packet. encapsulates a list of and the current position within that list. The commands in the list. The index of the current command. If the current command is a prepared statement, the index of the current prepared statement for that command. Returns true if the connection pool is empty, i.e., all connections are in use. Note that in a highly-multithreaded environment, the value of this property may be stale by the time it's returned. Returns the stored procedure cache for this , lazily creating it on demand. This method may return a different object after has been called. The returned object is shared between multiple threads and is only safe to use after taking a lock on the object itself. Examines all the objects in to determine if any have an owning that has been garbage-collected. If so, assumes that the connection was not properly disposed and returns the session to the pool. The that was used to create this .!-- This object must not be mutated. provides an internal abstraction over operations that can be cancelled: and . Returns a unique ID for all implementations of . Causes the effective command timeout to be reset back to the value specified by . As per the MSDN documentation, "This property is the cumulative time-out (for all network packets that are read during the invocation of a method) for all network reads during command execution or processing of the results. A time-out can still occur after the first row is returned, and does not include user processing time, only network read time. For example, with a 30 second time out, if Read requires two network packets, then it has 30 seconds to read both network packets. If you call Read again, it will have another 30 seconds to read any data that it requires." The method is called by public ADO.NET API methods to reset the effective time remaining at the beginning of a new method call. creates the data for an "execute query" command for one or more objects in a command list. Writes the payload for an "execute query" command to . The command list and its current position. This will be updated to the position of the next command to write (or past the end if there are no more commands). A for all the stored procedures in the command list, if any. The to write the payload to. true if a command was written; otherwise, false (if there were no more commands in the list). Returns an containing in the order they should be tried to satisfy the load balancing policy. provides an internal abstraction over and . provides an abstraction over iterating through a sequence of rows, where each row can fill an array of field values. represents an individual SQL statement that's been parsed from a string possibly containing multiple semicolon-delimited SQL statements. The bytes for this statement that will be written on the wire. The names of the parameters (if known) of the parameters in the prepared statement. There is one entry in this list for each parameter, which will be null if the name is unknown. The indexes of the parameters in the prepared statement. There is one entry in this list for each parameter; it will be -1 if the parameter is named. wraps a collection of objects. It implements to return the memory backing the statements to a shared pool. is a statement that has been prepared on the MySQL Server. Disposes and sets to null, ignoring any or that is thrown. An type. The object to dispose. Writes the text of to , encoded in UTF-8. The command. The cached procedures. The output writer. true if a complete command was written; otherwise, false. The statement is complete (apart from potentially needing a semicolon or newline). The statement needs a newline (e.g., to terminate a final comment). The statement needs a semicolon (if another statement is going to be concatenated to it). Implementations of write logs to a particular target. Returns true if logging for this logger is enabled at the specified level. The log level. true if logging is enabled; otherwise, false. Writes a log message to the target. The log level. The log message. See documentation for for notes on interpreting {0} within this string. If not null or empty, then includes formatting placeholders (e.g., {0}) which must be replaced with the arguments in , using or similar. If null or an empty array, then is a literal string; any curly braces within it must be treated as literal characters, not formatting placeholders. If not null, an associated with the log message. This method may be called from multiple threads and must be thread-safe. This method may be called even if would return false for ; the implementation must check if logging is enabled for that level. Implementations of create logger instances. Creates a logger with the specified name. This method may be called from multiple threads and must be thread-safe. Controls logging for MySqlConnector. Allows the to be set for this library. can be set once, and must be set before any other library methods are used. is an implementation of that does nothing.

Its primary difference from is that it's a reference type, so mutations to this object are visible to other objects that hold a reference to it. Hashes a password with the "Secure Password Authentication" method. The 20-byte random challenge (from the "auth-plugin-data" in the initial handshake). The password to hash. A 20-byte password hash. See Secure Password Authentication. Helper class to translate NegotiateStream framing for SPNEGO token into MySQL protocol packets. Serves as underlying stream for System.Net.NegotiateStream to perform MariaDB's auth_gssapi_client authentication. NegotiateStream protocol is described in e.g here https://winprotocoldoc.blob.core.windows.net/productionwindowsarchives/MS-NNS/[MS-NNS].pdf We only use Handshake Messages for authentication.

The table name shouldn't be quoted or escaped. Defines the number of rows to be processed before generating a notification event. Occurs every time that the number of rows specified by the property have been processed, and once after all rows have been copied (if is non-zero). Receipt of a RowsCopied event does not imply that any rows have been sent to the server or committed. A collection of objects. If the columns being copied from the data source line up one-to-one with the columns in the destination table then populating this collection is unnecessary. Otherwise, this should be filled with a collection of objects specifying how source columns are to be mapped onto destination columns. If one column mapping is specified, then all must be specified.

Each new connection opened for a connection pool uses the next host name (sequentially with wraparound). Each new connection tries to connect to the first host; subsequent hosts are used only if connecting to the first one fails. Servers are tried in random order. Servers are tried in ascending order of number of currently-open connections. Gets or sets a value that indicates whether the bulk copy operation should be aborted. Gets a value that returns the number of rows copied during the current bulk copy operation. Represents the method that handles the event of a . SSL connection options. Do not use SSL.
