SystemDataSQLiteSQLiteExceptionSQL logic error2 values for 5 columns
This exception usually occurs when there is a mismatch between the number of columns in a database table and the number of values being inserted or updated.
To resolve this issue, you need to ensure that the number of values you are providing matches the number of columns in the table. Here are a few steps you can take to fix this error:
-
Check the table structure: Verify that the table you are inserting or updating data into has the correct number of columns and their corresponding data types.
-
Verify the SQL statement: Double-check your SQL statement to ensure that you are providing the correct number of values for each column in the table.
-
Check for default values: If any of the columns in the table have default values defined, make sure you are not explicitly providing values for those columns unless necessary.
-
Use parameterized queries: Instead of directly embedding values into the SQL statement, consider using parameterized queries. This approach helps prevent SQL injection attacks and also ensures that the correct number of values are provided for each column.
Here's an example of a parameterized query in C# using SQLite:
string sql = "INSERT INTO myTable (column1, column2, column3) VALUES (@value1, @value2, @value3)";
using (SQLiteConnection connection = new SQLiteConnection(connectionString))
{
using (SQLiteCommand command = new SQLiteCommand(sql, connection))
{
command.Parameters.AddWithValue("@value1", value1);
command.Parameters.AddWithValue("@value2", value2);
command.Parameters.AddWithValue("@value3", value3);
connection.Open();
command.ExecuteNonQuery();
}
}
By following these steps, you should be able to resolve the "SQL logic error - 2 values for 5 columns" exception
