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.

Constructor Detail

SqlStandardControl

public SqlStandardControl()

Method Detail

getStaticInputValues

public Object getStaticInputValues()

Returns 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!

Specified by:

getStaticInputValues in interface SqlControl

Returns:

the object used for the SQL statement static input values

setStaticInputValues

public SqlStandardControl setStaticInputValues(Object staticInputValues)

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!

Parameters:

staticInputValues - the object used for the SQL statement static input values

Returns:

this instance

getMaxTimeout

public int getMaxTimeout()

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

Specified by:

getMaxTimeout in interface SqlControl

Returns:

the max SQL execution time

setMaxTimeout

public SqlStandardControl setMaxTimeout(int maxTimeout)

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

Parameters:

maxTimeout - the max SQL execution time

Returns:

this instance

getFirstResult

public int getFirstResult()

Returns 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.

Specified by:

getFirstResult in interface SqlControl

Returns:

the first SQL execution output row

setFirstResult

public SqlStandardControl setFirstResult(int firstResult)

Sets 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.

Parameters:

Returns:

this instance

getMaxResults

public int getMaxResults()
