Network packet size is the size of the tabular data stream TDS packets used to communicate between applications and the relational Database Engine. The default packet size is 4 KB, and is controlled by the network packet size configuration option. Before SQL Server , all versions supported bytes for all index types. The maximum number of bytes in a clustered index key cannot exceed in SQL Server.
For a nonclustered index key, the maximum is bytes. You can define a key using variable-length columns whose maximum sizes add up to more than the limit. However, the combined sizes of the data in those columns can never exceed the limit. In a nonclustered index, you can include extra non-key columns, and they do not count against the size limit of the key.
The non-key columns might help some queries perform better. No limit for a hash index, as long as all index keys fit in-row. On a memory-optimized table, a nonclustered index cannot have key columns whose maximum declared sizes exceed bytes. It is irrelevant whether the actual data in the key columns would be shorter than the maximum declared sizes. For a hash index key, there is no hard limit on size. For indexes on memory-optimized tables, there is no concept of included columns, since all indexes inherently cover of all columns.
For a memory-optimized table, even though the row size is bytes, some variable-length columns can be physically stored outside those bytes. However, the maximum declared sizes of all key columns for all indexes on a table, plus any additional fixed-length columns in the table, must fit in the bytes. SQL Server supports row-overflow storage, which enables variable length columns to be pushed off-row.
Only a byte root is stored in the main record for variable length columns pushed out of row. This feature allows limit that is effectively higher than in previous releases of SQL Server. For more information, see Large Row Support. Starting SQL Server Variable length columns are pushed off-row if the maximum sizes for all the columns in the table exceeds bytes; this action is a compile-time decision.
Only an 8-byte reference is stored in-row for columns stored off-row. Bytes per varchar max , varbinary max , xml , text , or image column. If the table contains one or more XML indexes, the clustering key of the user table is limited to 31 columns because the XML column is added to the clustering key of the primary XML index. In SQL Server, you can include non-key columns in a nonclustered index to avoid the limitation of a maximum of 32 key columns.
For more information, see Create Indexes with Included Columns. Tables that include sparse column sets include up to 30, columns. See sparse column sets. Different limits apply to sparse column sets. Later versions of SQL Server do not impose such a strict limit. For restrictions, see Create Foreign Key Relationships.
If a stored procedure accesses more than 64 databases, or more than two databases in interleaving, you will receive an error. Objects include tables, views, stored procedures, user-defined functions, triggers, rules, defaults, and constraints.
The sum of the number of all objects in a database cannot exceed 2,,,
