Functions | |
| System::Void | OSGeo::FDO::Commands::SQL::Close () |
| Closes the ISQLDataReader object, freeing any resources it may be holding. | |
| System::Boolean | OSGeo::FDO::Commands::SQL::GetBoolean (System::String *name) |
| Gets the Boolean value of the specified column. No conversion is performed, thus the column must be DataType_Boolean or an exception is thrown. | |
| System::Byte | OSGeo::FDO::Commands::SQL::GetByte (System::String *name) |
| Gets the byte value of the specified column. No conversion is performed, thus the column must be DataType_Byte or an exception is thrown. | |
| System::String * | OSGeo::FDO::Commands::SQL::GetColumnName (System::Int32 index) |
| Gets the name of the column at the given ordinal position. | |
| OSGeo::FDO::Schema::DataType | OSGeo::FDO::Commands::SQL::GetColumnType (System::String *name) |
| Gets the data type of the column with the specified name. | |
| System::DateTime | OSGeo::FDO::Commands::SQL::GetDateTime (System::String *name) |
| Gets the date time value of the specified column. No conversion is performed, thus the column must be DataType_DateTime or an exception is thrown. | |
| System::Double | OSGeo::FDO::Commands::SQL::GetDouble (System::String *name) |
| Gets the double-precision floating point value of the specified column. No conversion is performed, thus the column must be of type Double or an exception is thrown. | |
| System::Byte | OSGeo::FDO::Commands::SQL::GetGeometry (System::String *name)[] |
| Gets the geometry value of the specified column as a byte array in FGF format. No conversion is performed, thus the column must be of Geometric type or an exception is thrown. | |
| System::Int16 | OSGeo::FDO::Commands::SQL::GetInt16 (System::String *name) |
| Gets the signed 16-bit integer value of the specified column. No conversion is performed, thus the column must be DataType_Int16 or an exception is thrown. | |
| System::Int32 | OSGeo::FDO::Commands::SQL::GetInt32 (System::String *name) |
| Gets the signed 32-bit integer value of the specified column. No conversion is performed, thus the column must be DataType_Int32 or an exception is thrown. | |
| System::Int64 | OSGeo::FDO::Commands::SQL::GetInt64 (System::String *name) |
| Gets the signed 64-bit integer value of the specified column. No conversion is performed, thus the column must be DataType_Int64 or an exception is thrown. | |
| OSGeo::FDO::Expression::LOBValue * | OSGeo::FDO::Commands::SQL::GetLOB (System::String *name) |
| Gets a LOBValue reference. The LOB is fully read in and data available. Because no conversion is performed, the property must be DataType_BLOB or DataType_CLOB etc. (a LOB type). | |
| OSGeo::FDO::Common::IStreamReader * | OSGeo::FDO::Commands::SQL::GetLOBStreamReader (System::String *name) |
| Gets a reference of the specified LOB property as a BLOBStreamReader or CLOBStreamReader etc. to allow reading in blocks of data. Because no conversion is performed, the property must be DataType_BLOB or DataType_CLOB etc. (a LOB type) Cast the IStreamReader to the appropiate LOB Stream Reader. | |
| OSGeo::FDO::Schema::PropertyType | OSGeo::FDO::Commands::SQL::GetPropertyType (System::String *name) |
| Gets property type of the column with the specified name. This is used to indicate if a given column is a geometric property or a data property. If the column is a PropertyType_DataProperty, then GetColumnType can be used to find the data type of the column. | |
| System::Single | OSGeo::FDO::Commands::SQL::GetSingle (System::String *name) |
| Gets the single-precision floating point value of the specified column. No conversion is performed, thus the column must be DataType_Single or an exception is thrown. | |
| System::String * | OSGeo::FDO::Commands::SQL::GetString (System::String *name) |
| Gets the string value of the specified column. No conversion is performed, thus the column must be DataType_String or an exception is thrown. | |
| System::Boolean | OSGeo::FDO::Commands::SQL::IsNull (System::String *name) |
| Returns true if the value of the specified column is null. | |
| System::Boolean | OSGeo::FDO::Commands::SQL::ReadNext () |
| Advances the reader to the next item. The default position of the reader is prior to the first item. Thus, you must call ReadNext to begin accessing any data. | |
