C# Класс Azavea.Open.DAO.PostgreSQL.PostgreSqlDescriptor

This class is a ConnectionDescriptor implementation for using FastDAO to communicate with a PostGreSQL / PostGIS database. Thought it is named "PostGreSqlDescriptor", it supports spatial queries and data if you have PostGIS installed.
Наследование: Azavea.Open.DAO.SQL.AbstractSqlConnectionDescriptor, ITransactionalConnectionDescriptor

Метод Описание
BeginTransaction ( ) : ITransaction

Begins the transaction. Returns a transaction object that you should use for operations you wish to be part of the transaction. NOTE: You MUST call Commit or Rollback on the returned ITransaction when you are done.
CaseInsensitiveLikeOperator ( ) : string
ColumnAliasPrefix ( ) : string
ColumnAliasSuffix ( ) : string
CreateDataAccessLayer ( ) : IDaLayer
CreateNewAdapter ( IDbCommand cmd ) : DbDataAdapter
CreateNewConnection ( ) : DbConnection
HasCaseInsensitiveLikeOperator ( ) : bool
MakeConnectionString ( string server, string port, string database, string user, string password, string encoding ) : string

Assembles a PostGreSQL/PostGIS connection string that can be used to get a database connection. All the parameters are optional for the purposes of this method, although obviously it would be possible to create a useless connection string if you leave out important parameters.
MakeModulusClause ( string columnName ) : SqlClauseWithValue
MakeSequenceValueQuery ( string sequenceName ) : string
NeedAsForColumnAliases ( ) : bool
NeedToAliasColumns ( ) : bool
PostgreSqlDescriptor ( Config config, string component, ConnectionInfoDecryptionDelegate decryptionDelegate ) : System

This constructor reads all the appropriate values from our standard config file in the normal format.
PostgreSqlDescriptor ( string server, string port, string database, string user, string password, string encoding ) : System

Constructor that lets you pass everything as parameters rather than requiring a config.
SetParametersOnCommand ( IDbCommand cmd, IEnumerable parameters ) : void
TableAliasPrefix ( ) : string
