Field Detail

staticInputValues

private Object staticInputValues

The object used for the SQL statement dynamic input values. The class of this object is also named as the input class or the dynamic parameters class. The exact class type isn't important, all the parameters settled into the SQL prepared statement are picked up using the reflection API.

maxTimeout

private int maxTimeout

The max SQL execution time. This parameter can help to protect production system against ineffective SQL query commands. The value is in milliseconds.

firstResult

private int firstResult

The first SQL execution output row to be returned in the case we need to skip some rows in the result set. The primary usage is to support the pagination.

maxResults

private int maxResults

The max number of SQL execution output rows, which can be returned in the result list. The primary usage is to support the pagination.

order

private SqlOrder order

The ordering directive list. Using the class SqlOrder the ordering rules can be chained. Every ordering rule in this chain should correspond to one META SQL ordering statement.

moreResultClasses

private Map<String,Class<?>> moreResultClasses

More result classes used for the return values, like the collections classes or the collections items. They are used mainly for the one-to-one, one-to-many and many-to-many associations.

features

private Map<String,Object> features

The optional features. These features are defined in the statement execution scope. In the case of conflict with the optional features defined in sthe statement/global scope, their priority is higher.

processingId

private String processingId

The unique ID of the executed statement based on input values combination. This ID can be used for the caching purposes to optimize the SqlMetaStatement.process(org.sqlproc.engine.impl.SqlMetaStatement.Type, Object, SqlControl, org.sqlproc.engine.SqlEngine) The generation of the final ANSI SQL statement from the META SQL statement is influenced by the input values combination. This ID is an indicator of the uniqueness these input values. For more info please see the tutorials.

fetchSize

private int fetchSize

Returns the fetch size of SQL execution output rows, which can be returned in one SQL statement.

Constructor Detail

SqlStandardControl

public SqlStandardControl()

SqlStandardControl

public SqlStandardControl(SqlControl sqlControl)

Merging constructor.

Method Detail

getStaticInputValues

public Object getStaticInputValues()

Sets the object used for the SQL statement static input values. The class of this object is also named as the input class or the static parameters class. The exact class type isn't important, all the parameters injected into the SQL query command are picked up using the reflection API. Compared to dynamicInputValues input parameters, parameters in this class should't be produced by an end user to prevent SQL injection threat!
