how to get SqlQueryModel row count accurately

To get the row count accurately for a SqlQueryModel, you can use the rowCount() function provided by the model. Here is an example:

SqlQueryModel *model = new SqlQueryModel();
model->setQuery("SELECT * FROM myTable");

int rowCount = model->rowCount();

The rowCount() function returns the number of rows in the model. Note that the row count may be limited by the query or the database settings, so it may not be the total number of rows in the table.

Also, keep in mind that if the query includes GROUP BY or DISTINCT clauses, the row count will not match the actual number of distinct rows in the table.
