I am using QSqlTableModel
I created a table in the database with 15 columns, now I want to add two more columns with it
model_repo-> submitAll () returns true but no rows are added to the table, is there another way to add rows to the database? Is the number of columns in the database limited? -

The number of columns is not limited, or certainly nowhere near 15 columns.
Whether any rows should be added to database viasubmitAll()depends on what you have previously done in the model to add rows?
Adding new columns has nothing to do withsubmitAll().
It seems very unclear whether you are adding columns or rows. You certainly should not be mixing the two! Adding new columns requires very different code from adding rows.
