Answer Posted / satish v itagi
ExecuteNonQuery is used to inserts, updates, deletes.
ExecuteScaler is used to return values at a stretch; and
can do data modifications too.
ExecuteReader is forward only reading of row by row.
The number of readers that can be open at a time has
limitation (255)
Execute Scaler has no such restriction. You can use
sqlparameters (output) to get more than one field value,
you can use multiple queries to get more than one result.
Because of less overheads, ExecuteReader has a slight
performance advantage but has limitations.
