On this page: Sql Server Row Size LimitOther Posts you might also like Once again I've run into a limitation of SQL Server that really threw me off. SQL Server's Row Byte size is limited somewhere right around 8k bytes for physical data stored in the database. This means if you ...
The nonclustered index also has one LOB_DATA allocation unit per partition if it contains large object (LOB) columns. Additionally, it has one ROW_OVERFLOW_DATA allocation unit per partition if it contains variable length columns that exceed the 8,060-byte row size limit....
Columns that don't fit in the 8,060-byte row size limit are placed off-row, in a separate internal table. Each off-row column has a corresponding internal table, which in turn has a single nonclustered index. For details about these internal tables used for off-row columns, see sys....
8SQL Server supports row-overflow storage which enables variable length columns to be pushed off-row. Only a 24-byte root is stored in the main record for variable length columns pushed out of row; because of this, the effective row limit is higher than in previous releases of SQL Server....

ROW_OVERFLOW_DATA Remember the introduction? so, when the row exceeds the 8,060-byte limit, SQL Server then moves one or more of the variable-lengthcolumnsto pages in the ROW_OVERFLOW_DATA allocation unit. We still have a limitation here for the row size. Though the combined width of the...
1 row in set (0.09 sec) 1. 2. 3. 4. 5. 6. 7. 此时InnoDB的缓冲池的大小为:134217728/1024/1024=128M。 如果要修改缓冲池大小为256M: set global innodb_buffer_pool_size=268435456; 1. 或者修改配置文件: [server] innodb_buffer_pool_size = 268435456 ...
