Connection.Options (gb.db)
自从 3.18
Return or set the connection options.
These options are specific to the database type.
This property must be set before opening the connection.
Modifying an option after the connection has been opened has no effect.
At the moment, all MySQL and PostgreSQL connection options should be supported.
Other database drivers have no options at the moment.
Unknown options are silently ignored.
MySQL options
The list of MySQL options is described here:
https://dev.mysql.com/doc/c-api/8.0/en/mysql-options.html
The name of the option is its MySQL name, with the
MYSQL_
or
MYSQL_OPT_
prefix removed.
The name is case insensitive.
The value of the
PROTOCOL
,
SSL_MODE
and
SSL_FIPS_MODE
options, that take their value among integer constants,
is defined by a string corresponding to the value part of the constant symbol.
Example
MyConnection.Options["PROTOCOL"] = "TCP"
MyConnection.Options["READ_TIMEOUT"] = 30
MyConnection.Options["SSL_MODE"] = "REQUIRED"
MyConnection.Options["SSL_FIPS_MODE"] = "OFF"
PostgreSQL options
The list of PostgreSQL options is described here:
https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-PARAMKEYWORDS
The name of the option is its PostgreSQL name unmodified.
The name is case insensitive.
All options values are converted to string before being sent to the PostgreSQL API.
Example
MyConnection.Options["connect_timeout"] = 15
MyConnection.Options["keepalive"] = 0
MyConnection.Options["sslmode"] = "required"
