[MSSQL]datatype support

[BillyYccc]

currently we only support a small set of all the datatypes, we should expand the support and improve the current data type implmentation(such as NUMERIC).

Data type support checklist:

Note some data types have both fixed-length & vairable-length column, we need to support them all.

Numeric

• NUMERIC & DECIMAL (HIGH PRIORITY)
• BIT
• float & real
• int, bigint, smallint, tinyint
• money & smallmoney

String & Binary

• binary & varbinary
• varchar(max) and varbinary(max)
• char & varchar
• nchar & nvarchar (HIGH PRIORITY)
• ntext, text & image

date & time

• date
• datetime
• datetime2 (HIGH PRIORITY)
• datetimeoffset (HIGH PRIORITY)
• smalldatetime
• time

other

• guid

xml, GUID, spatial data types, etc...

I agree that numeric/decimal, and datetime2 are very high priority.

After that I would vote for image, text, and varbinary.

@BillyYccc about NUMERIC & DECIMAL (supported but do need some changes): which changes are needed? I couldn't find any comment or todos in the code

[BillyYccc]

I remember the scales are not handled in a right way.

@BillyYccc would you mind filing a separate issue for this please?

OK I'll take care of this. Le ven. 26 mars 2021 à 15:44, Billy Yuan ***@***.***> a écrit :
