OracleCommand::ExecuteOracleScalar Method ()

 

Executes the query, and returns the first column of the first row in the result set returned by the query as an Oracle-specific data type. Extra columns or rows are ignored.

Namespace:   System.Data.OracleClient
Assembly:  System.Data.OracleClient (in System.Data.OracleClient.dll)

public:
Object^ ExecuteOracleScalar()

Return Value

Type: System::Object^

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.

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();
