System::Object ^ ExecuteOracleScalar();public object ExecuteOracleScalar ();member this.ExecuteOracleScalar : unit -> objPublic Function ExecuteOracleScalar () As ObjectReturns
The first column of the first row in the result set as an Oracle-specific data type, or a null reference if the result is a REF CURSOR.
Remarks
Use the ExecuteOracleScalar method to retrieve a single value (for example, an aggregate value) from a database. This requires less code than using the ExecuteReader method, and then performing the operations necessary to generate the single value from the data returned by an OracleDataReader.
A typical ExecuteOracleScalar query can be formatted as in the following C# example:
command.CommandText = "SELECT COUNT(*) AS NumberOfRegions FROM Region";
count = command.ExecuteOracleScalar();
