SchemaEnum
Specifies the type of schema Recordset that the OpenSchema method retrieves.
Remarks
Additional information about the function and columns returned for each ADO constant can be found in topics in Appendix B: Schema Rowsets of the OLE DB Programmer's Reference. The name of each topic is listed in parentheses in the Description section of the following table.
Additional information about the function and columns returned for each ADO MD constant can be found in topics in OLE DB for OLAP Objects and Schema Rowsets in the OLE DB for Online Analytical Processing (OLAP) documentation. The name of each topic is listed in parentheses in the Description column of the following table.
You can translate the data types of columns in the OLE DB documentation to ADO data types by referring to the Description column of the ADO DataTypeEnum topic. For example, an OLE DB data type of DBTYPE_WSTR is equivalent to an ADO data type of adWChar.
ADO generates schema-like results for the constants, adSchemaDBInfoKeywords and adSchemaDBInfoLiterals. ADO creates a Recordset, and then fills each row with the values returned respectively by the IDBInfo::GetKeywords and IDBInfo::GetLiteralInfo methods. Additional information about these methods can be found in the IDBInfo section of the OLE DB Programmer's Reference.
