Data Type Mapping for Azure SQL Database
This section lists the mapping of data types for Azure SQL Database.
Azure SQL Database as Source

| bit | Native | bit |
| money | Native | money |
| smallmoney | Native | smallmoney |
| float | Native | float |
| real | Native | real |
| date | Native | ansidate |
| datetime | Native | datetime |
| datetime2 | Native | datetime(2) |
| datetimeoffset | Native | datetimeoffset |

Azure SQL Database as Target
When Azure SQL Database is used as a target location, following is the mapping of HVR repository data types to the corresponding data type in Azure SQL Database.
Text in green cell indicates the native data type of the DBMS
