Connection Properties

The connection properties are the various options that can be used to establish a connection. This section provides a complete list of the options you can configure in the connection settings for this provider. Click the links for further details.

For more information on establishing a connection, see Establishing a Connection.

Authentication


PropertyDescription
AuthSchemeSpecifies the authentication scheme used to connect to the data source. This determines how the user or application credentials are validated. Choose an option supported by your MySQL server database.
ServerSpecifies the host name or IP address of the MySQL server to connect to. This property supports both single-server and clustered environments through comma-separated values.
PortSpecifies the port number used to connect to the MySQL server. This property supports both single-node and clustered environments. For clusters, you may specify a comma-separated list of ports that correspond to each server in the Server property.
UserSpecifies the authenticating user's user ID.
PasswordSpecifies the authenticating user's password.
DatabaseSpecifies the name of the MySQL database to connect to by default. This determines the active schema used for queries unless explicitly overridden.
DomainSpecifies the Windows domain name to use when the AuthScheme is NTLM, which enables Windows Integrated Authentication using the NTLM protocol. This value is required if the user account belongs to a domain other than the local machine or default network domain.
NTLMVersionSpecifies the version of the NTLM protocol to use when authenticating with Windows credentials. This setting is only applicable when AuthScheme=NTLM.
IntegratedUserSpecifies the Windows user account to be used when authenticating with NTLM. This value is only applicable when AuthScheme=NTLM and is used to explicitly identify the integrated user for domain-based authentication.
UseSSLThis property determines whether Secure Sockets Layer (SSL) is enabled for communication. By default, SSL is set to 'false', meaning that communications are not encrypted unless explicitly enabled.

AWS Authentication


PropertyDescription
AWSAccessKeySpecifies your AWS account access key. This value is accessible from your AWS security credentials page.
AWSSecretKeyYour AWS account secret key. This value is accessible from your AWS security credentials page.
AWSRoleARNThe Amazon Resource Name of the role to use when authenticating.

Azure Authentication


PropertyDescription
AzureTenantIdentifies the MySQL tenant being used to access data. Accepts either the tenant's domain name (for example, contoso.onmicrosoft.com ) or its directory (tenant) ID.

OAuth


PropertyDescription
OAuthClientIdSpecifies the client ID (also known as the consumer key) assigned to your custom OAuth application. This ID is required to identify the application to the OAuth authorization server during authentication.
OAuthClientSecretSpecifies the client secret assigned to your custom OAuth application. This confidential value is used to authenticate the application to the OAuth authorization server. (Custom OAuth applications only.).
ScopeSpecifies the scope of the authenticating user's access to the application, to ensure they get appropriate access to data. If a custom OAuth application is needed, this is generally specified at the time the application is created.

SSL


PropertyDescription
SSLClientCertSpecifies the TLS/SSL client certificate store for SSL Client Authentication (2-way SSL). This property works in conjunction with other SSL-related properties to establish a secure connection.
SSLClientCertTypeSpecifies the type of key store containing the TLS/SSL client certificate for SSL Client Authentication. Choose from a variety of key store formats depending on your platform and certificate source.
SSLClientCertPasswordSpecifes the password required to access the TLS/SSL client certificate store. Use this property if the selected certificate store type requires a password for access.
SSLClientCertSubjectSpecifes the subject of the TLS/SSL client certificate to locate it in the certificate store. Use a comma-separated list of distinguished name fields, such as CN=www.server.com, C=US. The wildcard * selects the first certificate in the store.
SSLServerCertSpecifies the certificate to be accepted from the server when connecting using TLS/SSL.

SSH


PropertyDescription
SSHAuthModeThe authentication method used when establishing an SSH Tunnel to the service.
SSHClientCertA certificate to be used for authenticating the SSHUser.
SSHClientCertPasswordThe password of the SSHClientCert key if it has one.
SSHClientCertSubjectThe subject of the SSH client certificate.
SSHClientCertTypeThe type of SSHClientCert private key.
SSHServerThe SSH server.
SSHPortThe SSH port.
SSHUserThe SSH user.
SSHPasswordThe SSH password.
SSHServerFingerprintThe SSH server fingerprint.
UseSSHWhether to tunnel the MySQL connection over SSH. Use SSH.

Firewall


PropertyDescription
FirewallTypeSpecifies the protocol the provider uses to tunnel traffic through a proxy-based firewall.
FirewallServerIdentifies the IP address, DNS name, or host name of a proxy used to traverse a firewall and relay user queries to network resources.
FirewallPortSpecifies the TCP port to be used for a proxy-based firewall.
FirewallUserIdentifies the user ID of the account authenticating to a proxy-based firewall.
FirewallPasswordSpecifies the password of the user account authenticating to a proxy-based firewall.

Proxy


PropertyDescription
ProxyAutoDetectSpecifies whether the provider checks your system proxy settings for existing proxy server configurations, rather than using a manually specified proxy server.
ProxyServerIdentifies the hostname or IP address of the proxy server through which you want to route HTTP traffic.
ProxyPortIdentifies the TCP port on your specified proxy server that has been reserved for routing HTTP traffic to and from the client.
ProxyAuthSchemeSpecifies the authentication method the provider uses when authenticating to the proxy server specified in the ProxyServer connection property.
ProxyUserProvides the username of a user account registered with the proxy server specified in the ProxyServer connection property.
ProxyPasswordSpecifies the password of the user specified in the ProxyUser connection property.
ProxySSLTypeSpecifies the SSL type to use when connecting to the proxy server specified in the ProxyServer connection property.
ProxyExceptionsSpecifies a semicolon-separated list of destination hostnames or IPs that are exempt from connecting through the proxy server set in the ProxyServer connection property.

Logging


PropertyDescription
LogfileSpecifes the file path to the log file where the provider records its activities, such as authentication, query execution, and connection details.
VerbositySpecifies the verbosity level of the log file, which controls the amount of detail logged. Supported values range from 1 to 5.
LogModulesSpecifies the core modules to include in the log file. Use a semicolon-separated list of module names. By default, all modules are logged.
MaxLogFileSizeSpecifies the maximum size of a single log file in bytes. For example, '10 MB'. When the file reaches the limit, the provider creates a new log file with the date and time appended to the name.
MaxLogFileCountSpecifies the maximum number of log files the provider retains. When the limit is reached, the oldest log file is deleted to make space for a new one.

Schema


PropertyDescription
LocationSpecifies the location of a directory containing schema files that define tables, views, and stored procedures. Depending on your service's requirements, this may be expressed as either an absolute path or a relative path.
BrowsableSchemasOptional setting that restricts the schemas reported to a subset of all available schemas. For example, BrowsableSchemas=SchemaA,SchemaB,SchemaC .
TablesOptional setting that restricts the tables reported to a subset of all available tables. For example, Tables=TableA,TableB,TableC .
ViewsOptional setting that restricts the views reported to a subset of the available tables. For example, Views=ViewA,ViewB,ViewC .

Caching


PropertyDescription
AutoCacheSpecifies whether the content of tables targeted by SELECT queries is automatically cached to the specified cache database.
CacheProviderThe namespace of an ADO.NET provider. The specified provider is used as the target database for all caching operations.
CacheConnectionSpecifies the connection string for the specified cache database.
CacheLocationSpecifies the path to the cache when caching to a file.
CacheToleranceNotes the tolerance, in seconds, for stale data in the specified cache database. Requires AutoCache to be set to True.
OfflineGets the data from the specified cache database instead of live MySQL data.
CacheMetadataDetermines whether the provider caches table metadata to a file-based cache database.

Miscellaneous


PropertyDescription
AllowUserVariablesSpecifies whether user-defined variables (prefixed with @) are allowed in SQL queries. When enabled, the driver treats these as in-query user variables instead of parameter placeholders, allowing advanced SQL scripting patterns, such as variable assignment and conditional logic.
CharactersetSpecifies the default client character set used by the provider for encoding queries it sends to the server.
DateTimeTimeZoneSpecifies the timezone to apply to DATETIME types.
EnsureKeepAliveSetting this property to 'true' means that provider pings the server before performing a request, so the driver knows if the connection has been dropped since the last request.
MaxRowsSpecifies the maximum number of rows returned for queries that do not include either aggregation or GROUP BY.
OtherSpecifies additional hidden properties for specific use cases., to be used only when our Support team advises it, to address specific issues. See Remarks for details.
QueryPassthroughThis option passes the query to the MySQL server as is.
ReadonlyToggles read-only access to MySQL from the provider.
ServerTimeZoneSpecifies the timezone identifier for the MySQL server, based on the current edition and platform. This setting controls how the driver interprets and converts datetime values between the server and client.
TimeoutThis setting defines how long (in seconds) an operation is allowed to run before the system automatically considers it as having timed out. If the operation does not finish within the specified time, a timeout error is thrown. The default value is set to 30 seconds.
TinyInt1TypeDefines the presentation type used to display small integer values.
ZeroDatesToNullThis property determines whether Date and DateTime values consisting entirely of zeros (for example, '0000-00-00' or '0000-00-00 00:00:00') are returned as NULL values. By default, this property is set to 'true', meaning any invalid date or datetime values represented as all zeros is returned as NULL instead of their original value.
