Basic SQL Server Data Types

  • Artigo

This topic describes how the Microsoft BizTalk Adapter for SQL Serversurfaces basic SQL Server data types.

Supported SQL Server Data Types

The following table shows how the SQL Server data types are surfaced by the SQL adapter:

SQL Server Data Type XSD type .NET type Comments
Bigint Long Long -
Binary Base64Binary Byte[] -
Bit Boolean Bool -
Char String String -
Date DateTime DateTime -
Datetime DateTime DateTime While writing data to a Datetime field, the adapter always stores the time in GMT. If you specify the time-zone information, the adapter uses that to convert the value to a valid GMT value, and writes it to the database table. For example, 12/31/2008T23:59:59+5:30 is written to the table as 12/31/2008 6:29:59 PM.

However, if you do not specify the time-zone information, the adapter considers the value to be in GMT already, and writes the same value to the table. For example, 12/31/2008T23:59:59 is written to the table as 12/31/2008 11:59:59 PM.
