QSqlQuery.isActive() is a boolean function that returns true if the query is active and false if it is not.
Here are a few examples of how it can be used in C++ code:
Example 1: QSqlQuery query; query.prepare("SELECT * FROM mytable"); query.exec(); if(query.isActive()){ //query is active }
In this example, we create a QSqlQuery object, prepare a SQL statement, execute it, and then check whether the query is active. If it is, we can do additional processing.
Example 2: QSqlQuery query; query.prepare("INSERT INTO mytable VALUES (:value)"); query.bindValue(":value", 10); query.exec(); if(!query.isActive()){ //error occurred }
In this example, we insert a value into a table using a prepared SQL statement with a bind value. We then check whether the query is active. If it is not, an error occurred during execution.
This function is part of the QSqlQuery class in the Qt library.
