Interface ExecutionProperties

public interface ExecutionProperties

MetaMatrix-specific execution properties. These execution properties can be set via the com.metamatrix.jdbc.api.Statement#setExecutionProperty(String, String) method. They affect the subsequent execution of all commands on that Statement instance.

Field Summary

static java.lang.String	ALLOW_DBL_QUOTED_VARIABLE By default treat the double quoted strings as variables in a ODBC connection.
static java.lang.String	AUTO_WRAP_OFF Transaction auto wrap constant - never wrap a command execution in a transaction and allow multi-source updates to occur outside of a transaction.
static java.lang.String	AUTO_WRAP_ON Transaction auto wrap constant - always wrap every non-transactional command execution in a transaction.
static java.lang.String	AUTO_WRAP_OPTIMISTIC Transaction auto wrap constant
static java.lang.String	AUTO_WRAP_PESSIMISTIC Transaction auto wrap constant - pessimistic mode assumes that any command execution might require a transaction to be wrapped around it.
static java.lang.String	DISABLE_LOCAL_TRANSACTIONS If true, will ignore autocommit for local transactions.
static java.lang.String	PLAN_NOT_ALLOWED
static java.lang.String	PROP_FETCH_SIZE Default fetch size to use on Statements if the fetch size is not explicitly set.
static java.lang.String	PROP_PARTIAL_RESULTS_MODE Execution property name for partial results mode
static java.lang.String	PROP_SQL_OPTIONS Additional options/hints for executing the command
static java.lang.String	PROP_TXN_AUTO_WRAP Execution property name for transaction auto wrap mode
static java.lang.String	PROP_XML_FORMAT Execution property name for XML format

static java.lang.String	RESULT_SET_CACHE_MODE Whether to use result set cache if it is available
static java.lang.String	SQL_OPTION_SHOWPLAN Passed as an option to PROP_SQL_OPTIONS
static java.lang.String	XML_COMPACT_FORMAT XML results format: XML results displayed in compact form
static java.lang.String	XML_TREE_FORMAT XML results format: XML results displayed as a formatted tree

AUTO_WRAP_OFF

static final java.lang.String AUTO_WRAP_OFF

Transaction auto wrap constant - never wrap a command execution in a transaction and allow multi-source updates to occur outside of a transaction.

See Also:

Constant Field Values

AUTO_WRAP_ON

static final java.lang.String AUTO_WRAP_ON

Transaction auto wrap constant - always wrap every non-transactional command execution in a transaction.

See Also:

Constant Field Values

AUTO_WRAP_PESSIMISTIC

static final java.lang.String AUTO_WRAP_PESSIMISTIC

Transaction auto wrap constant - pessimistic mode assumes that any command execution might require a transaction to be wrapped around it. To determine this an extra server call is made to check whether the command requires a transaction and a transaction will be automatically started. This is most accurate and safe, but has a performance impact.

Constant Field Values

AUTO_WRAP_OPTIMISTIC

static final java.lang.String AUTO_WRAP_OPTIMISTIC

Transaction auto wrap constant

Constant Field Values

RESULT_SET_CACHE_MODE

static final java.lang.String RESULT_SET_CACHE_MODE

Whether to use result set cache if it is available

Since:

4.2

PROP_FETCH_SIZE

static final java.lang.String PROP_FETCH_SIZE

Default fetch size to use on Statements if the fetch size is not explicitly set. The default is 500.

ALLOW_DBL_QUOTED_VARIABLE

static final java.lang.String ALLOW_DBL_QUOTED_VARIABLE
