Question: Write the DML code to add the first row of each table to the database.

Sol: To add the first row of table or if you want to change an existing row, INSERT statement is used. The INSERT statement adds rows to a table. In addition, INSERT specifies the table or view that data will be inserted into. Remember that rows in a table have no inherent order. You can only refer to rows by specific column values (usually key values). The ordering of rows in a result set is arbitrary (unless you use ORDER BY); they have no inherent position. The INSERT statement is sometimes referred to as an INSERT INTO statement.

The syntax for the INSERT statement is:

INSERT [INTO] Table_name

When inserting rows with the INSERT statement, these rules apply:

  • Inserting an empty string (‘ ‘) into a varchar or text column inserts a single space.
  • All char columns are right-padded to the defined length.
  • All trailing spaces are removed from data inserted into varchar columns, except in strings that contain only spaces. These strings are truncated to a single space.
  • If an INSERT statement violates a constraint, default or rule, or if it is the wrong data type, the statement fails and SQL Server displays an error message.
