Boolean TZAbstractDriver::AcceptsURL | ( | const string | Url | ) | [inherited] |
Returns true if the driver thinks that it can open a connection to the given URL.
Typically drivers will return true if they understand the subprotocol specified in the URL and false if they don't.
url | the URL of the database |
Reimplemented from IZDriver.
Definition at line 572 of file ZDbcConnection.pas.
IZConnection TZPostgreSQLDriver::Connect | ( | const string | Url, | |
TStrings | Info | |||
) |
Attempts to make a database connection to the given URL.
The driver should return "null" if it realizes it is the wrong kind of driver to connect to the given URL. This will be common, as when the JDBC driver manager is asked to connect to a given URL it passes the URL to each loaded driver in turn.
The driver should raise a SQLException if it is the right driver to connect to the given URL, but has trouble connecting to the database.
The java.util.Properties argument can be used to passed arbitrary string tag/value pairs as connection arguments. Normally at least "user" and "password" properties should be included in the Properties.
url | the URL of the database to which to connect | |
info | a list of arbitrary string tag/value pairs as connection arguments. Normally at least a "user" and "password" property should be included. |

IZPostgreSQLPlainDriver TZPostgreSQLDriver::GetPlainDriver | ( | const string | Url | ) | [protected] |
Gets plain driver for selected protocol.
Url | a database connection URL. |

TStrings TZAbstractDriver::GetPropertyInfo | ( | const string | Url, | |
TStrings | Info | |||
) | [inherited] |
Gets information about the possible properties for this driver.
The getPropertyInfo method is intended to allow a generic GUI tool to discover what properties it should prompt a human for in order to get enough information to connect to a database. Note that depending on the values the human has supplied so far, additional values may become necessary, so it may be necessary to iterate though several calls to getPropertyInfo.
url | the URL of the database to which to connect | |
info | a proposed list of tag/value pairs that will be sent on connect open |
