.SH "DESCRIPTION"
.PP
The \fBtdbc::mysql\fR driver provides a database interface that conforms
to Tcl DataBase Connectivity (TDBC) and allows a Tcl script to connect
to a MySQL database.
.PP
Connection to an MYSQL database is established by invoking
\fBtdbc::mysql::connection create\fR, passing it the name to give the
database handle and a set of \fI-option-value\fR pairs. The available
options are enumerated under CONNECTION OPTIONS below.
As an alternative, \fBtdbc::mysql::connection new\fR may be used to create
a database connection with an automatically assigned name. The return value
from \fBtdbc::mysql::connection new\fR is the name that was chosen for the
connection handle.
.PP
The side effect of \fBtdbc::mysql::connection create\fR is to create a
new database connection.. See \fBtdbc::connection(n)\fR for the
details of how to use the connection to manipulate a database.
.SH "CONNECTION OPTIONS"
.PP
The \fBtdbc::mysql::connection create\fR object command supports the
\fB-encoding\fR, \fB-isolation\fR, \fB-readonly\fR and \fB-timeout\fR
options common to all TDBC drivers. The \fB-encoding\fR option will
always fail unless the encoding is \fButf-8\fR; the database connection
always uses UTF-8 encoding to be able to transfer arbitrary Unicode
characters. The \fB-readonly\fR option must be \fB0\fR, because
MySQL does not offer read-only connections.
.PP
In addition, the following options are recognized:
.IP "\fB-host\fR \fIhostname\fR"
Connects to the host specified by \fIhostname\fR. This option must be
set on the initial creation of the connection; it cannot be changed
after connecting. Default is to connect to the local host.
.IP "\fB-port\fR \fInumber\fR"
Connects to a MySQL server listening on the port specified by \fInumber\fR.
This option may not be changed after connecting. It is used only when
\fIhost\fR is specified and is not \fBlocalhost\fR.
.IP "\fB-socket\fR \fIpath\fR"
Connects to a MySQL server listening on the Unix socket or named
pipe specified by \fIpath\fR . This option may not be changed after connecting.
It is used only when \fI-host\fR is not specified or is \fBlocalhost\fR.
.IP "\fB-user\fR \fIname\fR"
Presents \fIname\fR as the user name to the MySQL server. Default is the
current user ID.
.IP "\fB-passwd\fR \fIpassword\fR"
.IP "\fB-password\fR \fIpassword\fR"
These two options are synonymous. They present the given \fIpassword\fR as
the user's password to the MySQL server. Default is not to present a password.
.IP "\fB-database\fR \fIname\fR"
.IP "\fB-db\fR \fIname\fR"
These two options are synonymous.  They present the given \fIname\fR as the
name of the default database to use in MySQL queries. If not specified,
the default database for the current user is used.
.IP "\fB-interactive\fR \fIflag\fR"
The \fIflag\fR value must be a Boolean value. If it is \fBtrue\fR (or
any equivalent), the default timeout is set for an interactive user,
otherwise, the default timeout is set for a batch user. This option
is meaningful only on initial connection. When using the \fBconfigure\fR
method on a MySQL connection use the \fB-timeout\fR option to set the
timeout desired.
.IP \fB-ssl_ca\fR \fIstring\fR
.IP \fB-ssl_capath\fR \fIstring\fR
.IP \fB-ssl_cert\fR \fIstring\fR
.IP \fB-ssl_cipher\fR \fIstring\fR
.IP \fB-ssl_key\fR \fIstring\fR
These five options set the certificate authority, certificate authority
search path, SSL certificate, transfer cipher, and SSL key to the
given \fIstring\fR arguments. These options may be specified only
on initial connection to a database, not in the \fBconfigure\fR method
of an existing connection. Default is not to use SSL.
.SH EXAMPLES
.PP
.CS
tdbc::mysql::connection -user joe -passwd sesame -db joes_database
.CE
Connects to the MySQL server on the local host using the default
connection method, presenting user ID 'joe' and password 'sesame'.
Uses 'joes_database' as the default database name.
.SH "ADDITIONAL CONNECTION METHODS"
In addition to the usual methods on the tdbc::connection(n) object,
connections to a MySQL database support one additional method:
.IP "\fI$connection\fR \fBevaldirect\fR \fIsqlStatement\fR"
This method takes the given \fIsqlStatement\fR and interprets as
MySQL native SQL code and evaluates it without preparing it. The
statement may not contain variable substitutions. The result set
is returned as a list of lists, with each sublist being the list
of columns of a result row formatted as character strings. Note that
the string formatting is done by MySQL and not by Tcl, so details
like the appearance of floating point numbers may differ.
\fIThis command is not recommended\fR for anything where the usual
\fIprepare\fR or \fIpreparecall\fR methods work correctly. It is
provided so that data management language statements that are
not implemented in MySQL's prepared statement API, such as
\fBCREATE DATABASE\fR or \fBCREATE PROCEDURE\fR, can be executed.
