1, the database: 32767 database, a minimum of 1MB, up to 1TB.
2, Table: Each database has up to 2 billion tables.
3, column: Each table 1024, the maximum number of bytes per column to 8060 (excluding text and image sequence).
Each SQL Server database can store up to 2 billion tables, each table can have 1024. And the total number of rows of the table size is limited only by the available storage space. Each row can store up to 8,060 bytes. If you create a varchar, nvarchar, or varbinary column of the table, and the total number of bytes a column of more than 8,060 bytes, although you can still create this table, but there will be a warning message. If you try to insert more than 8,060 bytes for the row or rows to be updated as well as more than 8,060 the total number of bytes, an error message will appear and the statement fails.
