Detailed description

[static] QSqlQuery_BatchExecutionMode ValuesAsColumns

Description: Enum constant QSqlQuery::ValuesAsColumns

[static] QSqlQuery_BatchExecutionMode ValuesAsRows

Description: Enum constant QSqlQuery::ValuesAsRows

void addBindValue(const QVariant val,const QSql_QFlags_ParamTypeFlag type = QSql::In)

Description: Method void QSqlQuery::addBindValue(const QVariant &val, QFlags<QSql::ParamTypeFlag> type)

QSqlQuery assign(const QSqlQuery other)

Description: Method QSqlQuery &QSqlQuery::operator=(const QSqlQuery &other)

[const] void assign(const QSqlQuery other)

Description: Assign the contents of another object to self

This method assigns the contents of another object to self. This is a deep copy that does not only copy the reference but the actual content.

[const] int at

Description: Method int QSqlQuery::at()

void bindValue(string placeholder,const QVariant val,const QSql_QFlags_ParamTypeFlag type = QSql::In)

Description: Method void QSqlQuery::bindValue(const QString &placeholder, const QVariant &val, QFlags<QSql::ParamTypeFlag> type)

void bindValue(int pos,const QVariant val,const QSql_QFlags_ParamTypeFlag type = QSql::In)

Description: Method void QSqlQuery::bindValue(int pos, const QVariant &val, QFlags<QSql::ParamTypeFlag> type)

[const] QVariant boundValue(string placeholder)

Description: Method QVariant QSqlQuery::boundValue(const QString &placeholder)

[const] QVariant boundValue(int pos)

Description: Method QVariant QSqlQuery::boundValue(int pos)

void clear

Description: Method void QSqlQuery::clear()

void create

Description: Ensures the C++ object is created

Use this method to ensure the C++ object is created, for example to ensure that resources are allocated. Usually C++ objects are created on demand and not necessarily when the script object is created.

void destroy

Description: Explicitly destroy the object

Explicitly destroy the object on C++ side if it was owned by the Ruby interpreter. Subsequent access to this object will throw an exception. If the object is not owned by Ruby, this method will do nothing.

[const] bool destroyed?

Description: Returns a value indicating whether the object was already destroyed

This method returns true, if the object was destroyed, either explicitly or by the C++ side. The latter may happen, if the object is owned by a C++ object which got destroyed itself.

[const] const QSqlDriver ptr driver

Description: Method const QSqlDriver *QSqlQuery::driver()

[const] QSqlQuery dup

Description: Creates a copy of self

bool exec(string query)

Description: Method bool QSqlQuery::exec(const QString &query)

bool exec

Description: Method bool QSqlQuery::exec()

bool execBatch(const QSqlQuery_BatchExecutionMode mode = QSqlQuery::ValuesAsRows)

Description: Method bool QSqlQuery::execBatch(QSqlQuery::BatchExecutionMode mode)

[const] string executedQuery

Description: Method QString QSqlQuery::executedQuery()

void finish

Description: Method void QSqlQuery::finish()

bool first

Description: Method bool QSqlQuery::first()

void forwardOnly=(bool forward)

Description: Method void QSqlQuery::setForwardOnly(bool forward)

[const] bool isActive

Description: Method bool QSqlQuery::isActive()

[const] bool isActive?

Description: Method bool QSqlQuery::isActive()

[const] bool isForwardOnly

Description: Method bool QSqlQuery::isForwardOnly()

[const] bool isForwardOnly?

Description: Method bool QSqlQuery::isForwardOnly()

[const] bool isNull(int field)

Description: Method bool QSqlQuery::isNull(int field)

[const] bool isNull?(int field)

Description: Method bool QSqlQuery::isNull(int field)

[const] bool isSelect

Description: Method bool QSqlQuery::isSelect()

[const] bool isSelect?

Description: Method bool QSqlQuery::isSelect()

[const] bool isValid

Description: Method bool QSqlQuery::isValid()

[const] bool isValid?

Description: Method bool QSqlQuery::isValid()

[const] bool is_const_object?

Description: Returns a value indicating whether the reference is a const reference

This method returns true, if self is a const reference. In that case, only const methods may be called on self.

bool last

Description: Method bool QSqlQuery::last()

[const] QSqlError lastError

Description: Method QSqlError QSqlQuery::lastError()

[const] QVariant lastInsertId

Description: Method QVariant QSqlQuery::lastInsertId()

[const] string lastQuery

Description: Method QString QSqlQuery::lastQuery()

[static] new QSqlQuery new(QSqlResult ptr r)

Description: Constructor QSqlQuery::QSqlQuery(QSqlResult *r)

This method creates an object of class QSqlQuery.

[static] new QSqlQuery new(string query = QString(),QSqlDatabase db = QSqlDatabase())

Description: Constructor QSqlQuery::QSqlQuery(const QString &query, QSqlDatabase db)

This method creates an object of class QSqlQuery.
