The sqlite3 module implements the Python Database Programming specification and provides the interfaces to connect to the SQLite database and perform SQL operations.The ORDER BY clause further complements the LIMIT and OFFSET clauses in effectively deciding the LIMIT and OFFSET, while deleting the rows.ĭeleting the rows of a SQLite table from a Python Program:.OFFSET clause will exclude the first n number of rows specified by it and the remaining rows will be deleted.LIMIT clause accepts an expression that evaluates to an integer value and “only” that many number of rows will be deleted from the table.WHERE clause accepts a Boolean expression and all the rows for which the Boolean expression evaluates to TRUE, are deleted from the table.How various clauses of DELETE statement affects the number of rows deleted:.The number of rows deleted and the order in which the rows are deleted depend upon the following clauses.The DELETE SQL statement deletes one are more rows of an SQLite table.Sql.js allows you to easily import and export SQLite databases.
