With this example we are going to demonstrate how to get the JDBC Connection parameters. In short, to get the JDBC Connection parameters you should:<\/p>\n
forName(String className)<\/code> API method of the Class<\/a>.<\/li>\n- Get the Driver<\/a> Instance. Invoke the
getDriver(String url)<\/code> of the DriverManager<\/a>, using the database URL.<\/li>\n- Get available properties, using the
getPropertyInfo(String url, Properties info)<\/code> of the Driver. It will return an array of DriverPropertyInfo<\/a> objects describing possible properties.<\/li>\n- For each one of the properties, get the name, value, description, choices and if property is required or not.<\/li>\n<\/ul>\n

With this feature enabled, the driver will delay loading the actual Blob data until the one of the retrieval methods (getInputStream(), getBytes(), and so forth) on the blob data stream has been accessed. For this to work, you must use a column alias with the value of the column to the actual name of the Blob. The feature also has the following restrictions: The SELECT that created the result set must reference only one table, the table must have a primary key; the SELECT must alias the original blob column name, specified as a string, to an alternate name; the SELECT must cover all columns that make up the primary key. \nChoices : [true, false, yes, no]\n\nProperty : emulateUnsupportedPstmts\nRequired : false\nValue : true\nDescription : Should the driver detect prepared statements that are not supported by the server, and replace them with client-side emulated versions?\nChoices : [true, false, yes, no]\n\nProperty : enablePacketDebug\nRequired : false\nValue : false\nDescription : When enabled, a ring-buffer of 'packetDebugBufferSize' packets will be kept, and dumped when exceptions are thrown in key areas in the driver's code\nChoices : [true, false, yes, no]\n\nProperty : enableQueryTimeouts\nRequired : false\nValue : true\nDescription : When enabled, query timeouts set via Statement.setQueryTimeout() use a shared java.util.Timer instance for scheduling.

Defaults to 'false'.\nChoices : [true, false, yes, no]\n\nProperty : useColumnNamesInFindColumn\nRequired : false\nValue : false\nDescription : Prior to JDBC-4.0, the JDBC specification had a bug related to what could be given as a \"column name\" to ResultSet methods like findColumn(), or getters that took a String property. JDBC-4.0 clarified \"column name\" to mean the label, as given in an \"AS\" clause and returned by ResultSetMetaData.getColumnLabel(), and if no AS clause, the column name.
