Data Type Mapping for Azure SQL Database

This section lists the mapping of data types for Azure SQL Database.

Azure SQL Database as Source

When Azure SQL Database is used as a source location, following is the mapping of data types in Azure SQL Database to the corresponding Fivetran HVR repository data type.

smallint	Native	smallint
tinyint	Native	tinyint
numeric	Native	numeric
decimal	Native	numeric
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
smalldatetime	Native	smalldatetime
time	Native	time
char	Native	char
varchar	Native	varchar
text	Native	text (sqlserver)
nchar	Native	nchar

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
