![]() In this example, I want to delete the names of Lucy, Stella, Max and Tiger from our original cats table here: We can specify which names to delete from the cats table using the IN operator. How to delete multiple rows using the IN operator in SQL The ids of 4-7 have been successfully deleted. We can see that rows 1-3 and 8-10 are left in our table. This is the result from that DELETE query: Here is the syntax for that: DELETE FROM cats In this example, we want to delete rows with ids of 4-7 inclusive. If we wanted to delete a number of rows within a range, we can use the AND operator with the BETWEEN operator. How to delete multiple rows using the BETWEEN operator with the AND operator in SQL Now the cats table is only showing the female cats. If we wanted to delete the rows with just the male cats, then we can use the gender="M" condition. One way we can delete multiple rows from our cats table is to change the condition from id to gender. How to Delete multiple rows from a table in SQL We can see that our DELETE query worked because Loki's information is no longer there. This is what the new cats table looks like: Here is the complete syntax to delete Loki's row: DELETE FROM cats In the second line, we are going to specify which row by using the id=8 after the WHERE clause. The first line of the DELETE query would look like this: DELETE FROM cats We want to delete the row with the id of 8 which is Loki's row. The columns would be id, name and gender. In this example, we have a table called cats that currently has ten rows in it. WHERE condition of which row(s) to delete This is the basic syntax for using the the DELETE query: DELETE FROM table_name I will also show you how to delete multiple rows from a table at once. In the article, I will walk you through how to use the DELETE query and WHERE clause to delete rows. from higher index to lower index, so that the dependency that I mentioned at the beginning of the answer does not occur.In SQL, you can delete a row in a table by using the DELETE query and the WHERE clause. Summary of this answer is: You have to turn on MultiSelection mode and Delete in reverse order, i.e. Selected_rows = table_lectionModel().selectedRows()įor row in row_indices: # sorted in descending order Then call remove_row_all_table() with table_widget: QTableWidget as parameter def remove_row_all_table(table_widget): Table_tSelectionMode(QAbstractItemView.MultiSelection) ![]() Select all rows for the given index range Pass rows you want to delete for example from 5 rows delete def setSel(selected: List, table_widget: QTableWidget): ![]() Deleting the First item will shift the remaining rows up, making row 1 and row 2 as row 0 and row 1 respectively, thus when you next delete row 1, row 2 (previously) will be deleted as it is now row 1.When you delete row index (for example ), and you start to delete from 0 -> 1 -> 2, then only row 0 and row 2 will be deleted!.If someone is still looking for an answer after implementing Anuj Bhasin's answer because the above solution will not work in many cases as expected.
