Detailed Description

Query parameter used to getting user input of constant values. It contains a message that is displayed to the user.

Member Function Documentation

◆ copy()

QueryParameterExpr * QueryParameterExpr::copy ( ) const
virtual
Returns
a deep copy of this object.

Reimplemented from KexiDB::ConstExpr.

Definition at line 583 of file expression.cpp.

◆ debugString()

TQString QueryParameterExpr::debugString ( )
virtual

Reimplemented from KexiDB::ConstExpr.

Definition at line 598 of file expression.cpp.

◆ getQueryParameters()

void QueryParameterExpr::getQueryParameters ( QuerySchemaParameterList & params)
virtual

Collects query parameters (messages and types) reculsively and saves them to params. The leaf nodes are objects of QueryParameterExpr class.

Reimplemented from KexiDB::ConstExpr.

Definition at line 609 of file expression.cpp.

◆ setType()

void QueryParameterExpr::setType ( Field::Type type)

Sets expected type of the parameter. The default is String. This method is called from parent's expression validate(). This depends on the type of the related expression. For instance: query "SELECT * FROM cars WHERE name=[enter name]", "[enter name]" has parameter of the same type as "name" field. "=" binary expression's validate() will be called for the left side of the expression and then the right side will have type set to String.

Definition at line 593 of file expression.cpp.

◆ toString()

TQString QueryParameterExpr::toString ( QuerySchemaParameterValueListIterator * params = 0)
virtual
Returns
string as a representation of this expression element by running recursive calls. param, if not 0, points to a list item containing value of a query parameter (used in QueryParameterExpr).

Reimplemented from KexiDB::ConstExpr.

Definition at line 604 of file expression.cpp.

◆ type()

Field::Type QueryParameterExpr::type ( )
virtual

Reimplemented from KexiDB::ConstExpr.

Definition at line 588 of file expression.cpp.

◆ validate()

bool QueryParameterExpr::validate ( ParseInfo & parseInfo)
virtual

Reimplemented from KexiDB::ConstExpr.

Definition at line 617 of file expression.cpp.
