Hi all, I am a beginner c# developer. I have a sql query.

SQL

MySql.Data.MySqlClient.MySqlCommand cmd = new MySql.Data.MySqlClient.MySqlCommand("DELETE FROM ranks WHERE rank_id NOT IN (SELECT DISTINCT(rank_id) FROM rank_transaction_type) AND rank_id = @rank_id",con);

How can you check if the delete query was successful and use it in 'if' statement. And store in variable.

for example:

if (queryworked == true)
{
}
else
{
}

Any help would be much appreciated. Thanking you in advance.

Solution 1

When you execute your query (for e.g. using the ExecuteNonQuery method[^]) has a return type that indicates the number of rows affected. You can use this value

E.g.

C#

int rowsAffected = cmd.ExecuteNonQuery();
if (rowsAffected >0)
{
}
else
{
}
