| There is no such unsigned integer data type in SQL Server, however you can constrain your data if you use check constraints.Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/Database maintenance routines:http://weblogs.sqlteam.com/tarad/archive/2004/07/02/1705.aspx |

Here are the integer data types, from BOL:quote:
Data type Range Storage bigint -2^63 (-9,223,372,036,854,775,808) to 2^63-1 (9,223,372,036,854,775,807) 8 Bytes int -2^31 (-2,147,483,648) to 2^31-1 (2,147,483,647) 4 Bytes smallint -2^15 (-32,768) to 2^15-1 (32,767) 2 Bytes tinyint 0 to 255 1 Byte
Then put a check constraint on the column to constrain the data to the range you want.Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/Database maintenance routines:http://weblogs.sqlteam.com/tarad/archive/2004/07/02/1705.aspx |

so for the range 0 - 65535 I can use int but for this range what I can do? |

| Add a check constraint to it. Look up check constraints in SQL Server Books Online if you don't understand what I mean.Tara KizerMicrosoft MVP for Windows Server System - SQL Serverhttp://weblogs.sqlteam.com/tarad/Database maintenance routines:http://weblogs.sqlteam.com/tarad/archive/2004/07/02/1705.aspx |
