OPLParameter Represents a parameter to an OPLCommand and optionally, its mapping to a DataSet column.public class OPLParameter : MarshalByRefObject, IDbDataParameter, IDataParameter, ICloneable Constructors public OPLParameter(); Initializes a new instance of the OPLParameter class.public OPLParameter(string parameterName, object value); Initializes a new instance of the OPLParameter class with the parameter name and a value of the new OPLParameter object.public OPLParameter(string parameterName, OPLDbType type); Initializes a new instance of the OPLParameter class with the parameter name and the data type.public OPLParameter(string parameterName, OPLDbType type, int size); Initializes a new instance of the OPLParameter class with the parameter name, the OPLDbType and the size.public OPLParameter(string parameterName, OPLDbType type, int size, string sourceColumn); Initializes a new instance of the OPLParameter class with the parameter name, the OPLDbType, the size, and the source column name.public OPLParameter(string parameterName, OPLDbType type, int size, ParameterDirection direction, Boolean isNullable, Byte precision, Byte scale, string sourceColumn, DataRowVersion sourceVersion, object value); Initializes a new instance of the OPLParameter class with the parameter name, the type of the parameter, the size of the parameter, a ParameterDirection, whether the parameter is nullable, the precision of the parameter, the scale of the parameter, the source column, a DataRowVersion to use, and the value of the parameter.Methods {public override string ToString ();}Gets a string containing the ParameterName.Properties public OPLDbType OPLDbType {get; set;} Gets or sets the OPLDbType of the parameter.Remarks The OPLDbType and DbType are linked. Therefore, setting the DbType changes the OPLType to a supporting OPLDbType. For a list of the supported data types, see the appropriate OPLDbType member.
