'Declaration Public Function ExecuteOracleScalar As Object 'Usage Dim instance As OracleCommand Dim returnValue As Object returnValue = instance.ExecuteOracleScalar
Return ValueThe 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.
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();
