Notice that if you assign another integer type such as BIGINT and UNSIGNED INT to the primary key column, this column will not be an alias for the rowid column.īecause the rowid table organizes its data as a B-tree, querying and sorting data of a rowid table are very fast. If a table has the primary key that consists of one column, and that column is defined as INTEGER then this primary key column becomes an alias for the rowid column. The first method is more useful because you can specify db. You can use this command in the following ways: > sphelp ‘yourobjectname’ or. One can easily describe an object using this command. Tables that have rowid columns are called rowid tables. But to describe a table or object MS SQL Server provides a very useful command or built-in stored procedure sphelp. The rowid column is a key that uniquely identifies the rows in the table. When you create a table without specifying the WITHOUT ROWID option, SQLite adds an implicit column called rowid that stores 64-bit signed integer. You will see the Row count value on the right: Another option to get the number of rows in a table comes with the SQL Complete SSMS Add-in. In the Table Properties window, click on Storage. However, to make the current version of SQLite compatible with the earlier version, SQLite allows the primary key column to contain NULL values. Open SQL Server Management studio > Connect to the database instance > Expand Tables > Right-click on tblCustomer > Properties. It means that the primary key column has an implicit NOT NULL constraint. In SQL standard, the primary key column must not contain NULL values.
