Member Function Documentation

bindValue()

void Qx::SqlQuery::bindValue	(	const QString &	placeholder,
		const QVariant &	val )

Binds the value val to placeholder placeholder in the query.

Unlike QSqlQuery, values can be bound before the query is completely formed.

Note

Due to implementation constraints, ordered bindings are not supported.

database() [1/2]

SqlDatabase * Qx::SqlQuery::database

(

)

Returns the database associated with the string.

database() [2/2]

const SqlDatabase * Qx::SqlQuery::database

(

)

const

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

hasDatabase()

bool Qx::SqlQuery::hasDatabase

(

)

const

Returns true if the query has an associated database, and therefore can be executed; otherwise, returns false.

string()

QString Qx::SqlQuery::string

(

)

const

Returns the current query string.
