EnsLib.SQL.CommonJ

abstract class EnsLib.SQL.CommonJ extends EnsLib.JavaGateway.Common

This class defines features shared by inbound and outbound SQL adapters, of both the ODBC and JDBC varieties It also can be instantiated to represent a collection of config settings used to connect to a JDBC driver. It also offers methods allowing an instance to be used as a Connection object on which JDBC gateway calls can be invoked

Properties

property ConnectionAttributes as %String(MAXLEN="");
A set of SQL Connection Attribute options.

For ODBC they are of the form attr:val,attr:val,...
For example, "AutoCommit:1"

For JDBC they are of the form attr=val;attr=val;...
For example, "TransactionIsolationLevel=TRANSACTION_READ_COMMITTED"

Note: if using a named JDBC SQL Gateway Connection as DSN, this value is optional but if present will override the value specified in the named JDBC SQL Gateway Connection's Properties field.
property DSN as %String(MAXLEN=1000);
This Data Source Name specifies the external datasource to connect to. If this name matches the name of a JDBC or ODBC 'Object/SQL Gateway connection' configured from the System Management Portal, the parameters from that specification will be used. Otherwise this value may be an ODBC DSN name configured in your OS, or a JDBC URL. Note: if a JDBC URL, then in addition to Credentials the JDBCDriver and JDBCClasspath settings must also be configured, and ConnectionAttributes will also apply if configured.
property JDBCClasspath as %String(MAXLEN=1000);
Classpath for JDBC driver classname, if needed in addition to the ones configured in the Java Gateway Service
property JDBCDriver as %String(MAXLEN=1000) [ Required ];
JDBC Driver classname - not used for ODBC DSN connections Note: if using a named SQL Gateway Connection as DSN, this value is optional but if present will override the value specified in the named JDBC SQL Gateway Connection's set of properties.
property JGClientEnsClassname as %String(MAXLEN=128) [ InitialExpression = "%Net.Remote.Java.JDBCGateway" ];
override and hard-code classname
property updatecount as %Integer;

Methods

method BindOutputParameter(pHS As %String, pNum As %Integer, pType As %Integer, pTypeName As %String) as %Status
method ConnectJ(pClientTimeout As %Numeric = 15, pInbound As %Boolean = 0, pJGTimeout As %Numeric = 5) as %Status
A shadow of the superclass JavaGateway Adapter Connect() method; in the subclass the SQL Adapter Connect() method overrides the superclass version and calls this one
method DSNSet(dsnstr As %String) as %Status
This is a Set accessor method for the DSN property.
method DescribeColumns(pHS As %String, Output pColInfo As %List) as %Status
method DescribeParameters(pHS As %String, pParmDescs, pParms) as %Status
method DisconnectJ(pInbound As %Boolean = 0)
Disconnect from the Java Gateway Client
method DropResultSet(pHS As %String) as %Status
DropResult
method DropStatement(pHS As %String) as %Status
method Fetch(pHS As %String) as %Status
method FetchAhead(hstmt, nSkip, nFetch) as %Status

This is a Set accessor method for the JDBCClasspath property.
method MoreResults(pHS As %String) as %Status
method RowCount(pHS As %String = "", pIndex As %Integer = 1) as %Integer
Return the last retrieved Update,Delete, or Stored Procedure row count values for the given statement handle
method SetConnectOption(opt, val) as %Status
method SetStmtOption(pHS As %String, opt, val) as %Status
method TestConnectionJ(pInbound As %Boolean = 0)
method Transact(type) as %Status
classmethod getConfigObj(pConfiguredUs As EnsLib.SQL.Common, pCredentials As Ens.Config.Credentials, pConn As %RegisteredObject) as EnsLib.SQL.CommonJ
Create a new configuration-object instance of this class, loading values from the DB if possible This new instance may contain values distinct from those defined in the Adapter if loaded indirectly from a %Library.Sys.SQLConnection object in the DB
classmethod isNetErr(pErrorText As %String) as %Boolean
Decide whether the text of an error returned from the driver represents a disconnection implying the need to re-connect. Override this method in a subclass if you encounter other error signatures that ought to be in this list, Also please contact InterSystems so that we may add the new codes to the base IsTextNetworkError() method.
