Helper classes
| Class Name | Description |
| oa_ds_info | Defines the name, number, value, and remarks field of a customized driver information property. |
| oa_types_info | Defines the information describing a data type supported by the data source. The values of the members can be set using setTypesInfo() or using the parameterized constructor. The method ipGetTypesInfo returns an array of oa_types_info objects if the IP code chooses to over ride the default type information. There is one entry in the array for each data type supported by the data source. |
| scalar_functions | Use the scalar_functions class to register user defined scalar functions. |
| schemaobj_column | The schemaobj_column class is used to define column objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_COLUMN. |
| schemaobj_fkeys | The schemaobj_fkeys class is used to define foreign key column objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_FKEY. |
| schemaobj_pkeys | The schemaobj_pkeys class is used to define primary key column objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_PKEY. |
| schemaobj_proc | The schemaobj_proc class is used to define stored procedure objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_PROC. |
| schemaobj_proccolumns | The schemaobj_proccolumns class is used to define stored procedure column objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_PROCCOLUMNS. |
| schemaobj_stat | The schemaobj_stat class is used to define index objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_STAT. |
| schemaobj_table | The schemaobj_table class is used to define table objects and to access the search conditions when ipSchema is called for ip.DAMOBJ_TYPE_TABLE. |
| xo_type | The xo_type class represents data type details about a column. An object of this type is returned by a call to dam_describeColDetail. |
