void Condition::addColumnCondition	(	const QString &	column,
		CompareOperator	op,
		const QString &	column2 )

Add a WHERE condition which compares a column with another column.

Parameters

column	The column that should be compared.
op	The operator used for comparison.
column2	The column column is compared to.

Definition at line 22 of file query.cpp.

addCondition()

void Query::Condition::addCondition

(

const Condition &

condition

)

Add a WHERE condition.

Use this method to build hierarchical conditions.

Definition at line 54 of file query.cpp.

addValueCondition() [1/3]

void Akonadi::Server::Query::Condition::addValueCondition ( const QString & column, CompareOperator op, const QList< qint64 > & value )

inline

Add a WHERE condition which compares a column with a given value.

This is an overload specially for passing a list of IDs, which is a fairly common case in Akonadi.

Parameters

column	The column that should be compared.
op	The operator used for comparison.
value	The value column is compared to.

Definition at line 91 of file query.h.

addValueCondition() [2/3]

void Akonadi::Server::Query::Condition::addValueCondition ( const QString & column, CompareOperator op, const QSet< qint64 > & value )

inline

Add a WHERE condition which compares a column with a given value.

This is an overload specially for passing a list of IDs, which is a fairly common case in Akonadi.

Parameters

column	The column that should be compared.
op	The operator used for comparison.
value	The value column is compared to.

Definition at line 105 of file query.h.

addValueCondition() [3/3]

void Condition::addValueCondition	(	const QString &	column,
		CompareOperator	op,
		const QVariant &	value )

Add a WHERE condition which compares a column with a given value.

Parameters

column	The column that should be compared.
op	The operator used for comparison
value	The value column is compared to.

Definition at line 12 of file query.cpp.

(

)

const

Returns if there are sub conditions.

Definition at line 39 of file query.cpp.
