OracleParameterCollection Class

Represents a collection of parameters relevant to an OracleCommand as well as their respective mappings to columns in a DataSet. This class cannot be inherited.

Namespace: System.Data.OracleClient
Assembly: System.Data.OracleClient (in system.data.oracleclient.dll)

public ref class OracleParameterCollection sealed : public DbParameterCollection
public final class OracleParameterCollection extends DbParameterCollection
public final class OracleParameterCollection extends DbParameterCollection

When using named parameters, the number of parameters in the collection must be equal to the number of named parameters within the command text, or the .NET Framework Data Provider for Oracle raises an error.

The .NET Framework Data Provider for Oracle does not support the question mark (?) placeholder for passing parameters to an SQL statement called by an OracleCommand of CommandType.Text. In this case, named parameters must be used. For example:

SELECT * FROM Customers WHERE CustomerID = :pCustomerID

When using named parameters in an SQL statement called by an OracleCommand of CommandType.Text, you must precede the parameter name with a colon (:). However, in a stored procedure, or when referring to a named parameter elsewhere in your code (for example, when adding OracleParameter objects to the Parameters property), do not precede the named parameter with a colon (:). The data provider supplies the colon automatically.

The following example creates multiple instances of OracleParameter through the OracleParameterCollection within the OracleDataAdapter. These parameters are used to select data within the database and then place the data in the DataSet. This example assumes that a DataSet and an OracleDataAdapter have already been created with the appropriate schema, commands, and connection.

No code example is currently available or this language may not be supported.
