To obtain the total number of records in a table using Flutter SQFLite, you can use the rawQuery
method to execute an SQL query that selects and counts all the records in the table.
Here's an example code snippet that demonstrates how to do this for a table called my_table
:
import 'package:sqflite/sqflite.dart';
Future<int> getTotalRecordsCount() async {
Database db = await openDatabase('my_database.db');
int count = Sqflite.firstIntValue(await db.rawQuery('SELECT COUNT(*) FROM my_table'));
return count;
}
In this code, we first open the database using the openDatabase
method. Then, we execute an SQL query using the rawQuery
method, which selects and counts all the records in the my_table
table. Finally, we return the count as an int
value.
Note that the firstIntValue
method is used to extract the count from the query result. This method returns the first value from the first row of the result set as an int
value. In this case, the value is the count of all the records in the table.
