As you are probably aware already, columns are used to organize data by categories. Each column has a series of fields under the column header. One of the actual purposes of a table is to display data that is available for each field under a particular column. Data entry consists of providing the necessary values of the fields of a table. Data is entered into a field and every time this is done, the database creates a row of data. This row is called a record. This means that entering data also self-creates rows. There are various ways you can perform data entry for a Microsoft SQL Server table: |
Probably the easiest and fastest way to enter data into a table is by using either Microsoft SQL Server Management Studio or Microsoft Visual Studio. Of course, you must first open the desired table from a database connection. In the Server Explorer, after expanding the connection to the database and the Tables nodes, right-click the desired table and click Show Table Data. If the table does not contain data, it would appear with one empty row. If some records were entered already, their rows would show and the table would provide an empty row at the end, expecting a new record. To perform data entry on a table, you can click in a cell. Each column has a title, called a caption, on top. This gray section on top is called a column header. In Microsoft SQL Server, it displays the actual name of the column. You refer to the column header to know what kind of data should/must go in a field under a particular column. This is why you should design your columns meticulously. After identifying a column, you can type a value. Except for text-based columns, a field can reject a value if the value does not conform to the data type that was set for the column. This means that in some circumstances, you may have to provide some or more explicit information to the user.
