Tables can be created with default values. VALUES (‘AllThingsSQL’,’1234′,’543 John Doe Way’,’Apt 7′,’Fantasy Land’,’IL’,’60430′,’United States’,’0′) Īs we can see, the resulting output would start at an initial value of 1.
INSERT INTO Company (CompanyName, CompanyNumber, AddressLine1, AddressLine2, City, State, PostalCode, Country, IsFortune500) We can then include an insert statement to see what the output would be. In the case of SQL Server we apply an initial value as well as the incremental increase for each value. For example, in SQL Server we would replace the first column with “CompanyId INT IDENTITY(1,1) PRIMARY KEY“.
This will allow the table to auto-populate an id with an increment of 1 starting from an initial value of 1. If we wanted to ensure that our table automatically applied an ID value to the CompanyId field, we could add the AUTOINCREMENT keyword. The database automatically applies a name to the primary key. Create Company Table w/ Primary KeyĪs we can see, all we need to include is the primary key keyword (in SQLite db) to apply the primary key value to the table. In the example of the Company table, we would want to make the CompanyId field our primary key. A primary key is normally used on a table as a unique identifier. We can easily include primary keys into a table. Let’s look at a few other create table examples. This is something to be aware of although theses limits are normally very high and never reached.
We can then continue to include as many columns needed with as many datatypes as needed. Create Company TableĪt its core, a table can be created at a bare minimum with one column. This is a simple example if we were looking to create a basic Company table. There are also important components that can be added to a table during its creation such as a primary key, identity columns, indexes and more. Creating a standard table is fairly straight-forward. Specifically for tables, we use the CREATE TABLE command. When creating any objects we use the CREATE keyword.
