Methods
method %OnClose() as %Status
Inherited description: This callback method is invoked by the %Close() method to
provide notification that the current object is being closed.
The return value of this method is ignored.
method Close()
Releases this Connection object's database and resources immediately instead of waiting for them to be automatically released
method Commit()
Makes all changes made since the previous commit/rollback permanent and releases any database locks currently held by this Connection object
method CreateStatement() as Statement
Creates a Statement object for sending SQL statements to the database
method GetAutoCommit() as %Boolean
Retrieves the current auto-commit mode for this Connection object
classmethod GetJdbcConnection(connectionInfo As %Library.DynamicObject) as %XDBC.Gateway.JDBC.Connection
method GetMetaData() as DatabaseMetaData
Retrieves a DatabaseMetaData object that contains metadata about the database to which this Connection object represents a connection
method GetSchema() as %String
Retrieves this Connection object's current schema name
method GetTransactionIsolation() as %Integer
Retrieves this Connection object's current transaction isolation level
method IsClosed() as %Boolean
Retrieves whether this Connection object has been closed
method IsReadOnly() as %Boolean
Retrieves whether this Connection object is in read-only mode
Returns true if the connection has not been closed and is still valid
Creates a Statement object for calling stored procedures
method PrepareStatement(sql As %String, resultSetType As %Integer = ..#TYPESCROLLFORWARDONLY, resultSetConcurrency As %Integer = ..#CONCURREADONLY) as Statement
Creates a statement object for sending parameterized SQL statements to the database
method Rollback()
Undoes all changes made in the current transaction and releases any database
locks currently held by this Connection object
method SetAutoCommit(autoCommit As %Boolean)
Sets this connection's auto-commit mode to the given state
method SetReadOnly(readOnly As %Boolean)
Puts this connection in read-only mode as a hint to the driver to enable database optimizations
method SetSchema(schema As %String)
Sets the given schema name to access
method SetTransactionIsolation(level As %Integer)
Attempts to change the transaction isolation level for this Connection object to the one given
level is 1, 2, 4 (Connection.TRANSACTION_REPEATABLE_READ) or 8 (Connection.TRANSACTION_SERIALIZABLE)
