Sqlite Table Has No Column Named Mobile Number Flutter
SQLite is a database management system that stores data in tables. Each table has a set of columns,
Sqlite Table Has No Column Named Mobile Number Flutter
When working with an SQLite database in Flutter, it's crucial to ensure that the table structure aligns with the expected data. If you encounter the error “table has no column named <column_name>”, it means that the column you are trying to query or insert data into does not exist in the table. This could be due to a typo in the column name, a mismatch between the table definition and the code, or a database upgrade that removed the column. Resolving this error involves verifying the table definition and ensuring that the code accessing the database is up-to-date.
