Currently, the user only has access to the most recent entry for that month, location or both. At the bottom of the browser there is a search that will allow the user to see camping trips by month, location or both. To clarify, the user logs a camping trip that includes: start_date, end_date, location, camping_site, weather, notes, and pictures. I want to be able to recall all entry's that satisfy parameters utilized. The user can recall 1 entry "row" based on 2 different parameters (month and/or location). I have created an html file that saves user inputs into an SQLite database. ![]() I am creating a camping log using SQLite. Example import 'm new to Flask and Python. Insert into MyPlayers values(7, 'James', 'Anderson', DATE(''), 'Burnley', 'England') įollowing JDBC program finds the number of rows in the above table and displays the value. Insert into MyPlayers values(6, 'Ravindra', 'Jadeja', DATE(''), 'Nagpur', 'India') Insert into MyPlayers values(5, 'Rohit', 'Sharma', DATE(''), 'Nagpur', 'India') Insert into MyPlayers values(4, 'Virat', 'Kohli', DATE(''), 'Delhi', 'India') Insert into MyPlayers values(3, 'Kumara', 'Sangakkara', DATE(''), 'Matale', 'Srilanka') Insert into MyPlayers values(2, 'Jonathan', 'Trott', DATE(''), 'CapeTown', 'SouthAfrica') Now, we will insert 7 records in MyPlayers table using INSERT statements − insert into MyPlayers values(1, 'Shikhar', 'Dhawan', DATE(''), 'Delhi', 'India') Let us create a table with name MyPlayers in MySQL database using CREATE statement as shown below − CREATE TABLE MyPlayers( Using count(*) function in the SELECT query you can get the number of rows in a table as − select count(*) from Table_Name but, it does not provides any method to find the number of rows in a table directly. The ResultSet interface provides various methods to find, the no.of columns, name of the column, type of the column etc. Initially this cursor is positioned before first row (default position). The ResultSet object contains a cursor/pointer which points to the current row. Whenever we execute SQL statements using the executeQuery() method, it returns a ResultSet object which holds the tabular data returned by the SELECT queries(in general). ![]()
