Methods
  NameDescription
Public methodCheckIfFkConstraintCanBeCreated
Checks if an fk constraint can be created between the fk side and the pk side specified.
Public methodClone

Protected methodConvertElementNameToString
Creates a string representation of the element specified for SQL query purposes.
Protected methodConvertSchemaElementToFullNameForSqlQuery
Converts the specified element to a full name to be used in a sql query. E.g. [catalog].[schema].[tablename] for sql server. It uses the WrapIdentifier method to create fragments for catalog/schema/table name (or view name). Override this method if the database doesn't support catalogs or schemas.
Public methodConvertStringToDBType
Converts the name specified to a DBType value.
Public methodCreateCatalogRetriever
Produces the DBCatalogRetriever instance to use for retrieving meta-data of a catalog.
Public methodCreateCommand(String)
Creates a new command with the query set as command text and a new connection object set as its connection. It sets the command timeout to the static command time set in the DDDriverbase class
Public methodCreateCommand(DbConnection, String)
Creates a new command with the query set as command text and the connection passed in set as its connection. It sets the command timeout to the static command time set in the DDDriverbase class
Public methodCreateConnection
Creates a connection object using the factory and sets the connection string
Public methodCreateConnectionDataCollector
Creates the connectiondata object to be used to obtain the required information for connecting to the database.

Public methodCreateParameter(DbCommand, DBStoredProcedureParameter)
Creates a new db parameter based on the passed in DBStoredProcedureParameter
Public methodCreateParameter(DbCommand, String, Object)
Creates a new parameter with the value specified. It's a different implementation as the other overloads: this overload doesn't set the DbType nor the size explicitly. Some providers need that like Sybase.
Public methodCreateParameter(DbCommand, String, DbType, Int32)
Creates a new parameter with the values specified and adds it to the parameter collection of the command specified
Public methodCreateParameter(DbCommand, String, DbType, Int32, Object)

Public methodCreateStoredProcCallCommand(String)
Creates a new command with the stored procedure call as the command text and a new connection object set as its connection. It sets the command timeout to the static command time set in the DDDriverbase class.
Public methodCreateStoredProcCallCommand(DbConnection, String)
Creates a new command with the stored procedure call as the command text and the connection object passed in as its connection. It sets the command timeout to the static command time set in the DDDriverbase class.
