The following excerpt from the Ch04UsingPrimaryKey.sql file shows how simple it is to include a PRIMARY KEY phrase in a column declaration. No additional constraints apply to the int1 column, but SSE treats the column as if it had both NOT NULL and UNIQUE constraints. The bit1 column is the only other column in the table. This column has a NOT NULL and its DEFAULT property set. CREATE TABLE T ( int1 int PRIMARY KEY, bit1 bit NOT NULL DEFAULT 0 ) The next excerpt from Ch04UsingPrimaryKey.sql includes five INSERT statements for the table created with the preceding CREATE TABLE index. code 39 excel free, police code 39 excel 2013, how to generate a barcode using asp.net c#, code 128 vb.net free, excel data matrix font, asp.net qr code reader open source qr code reader vb.net NET QR Code Barcode Reader - KeepAutomation.com

Introduction. In this tip, I'll cover a simple method to do with a QR code inside a standard control. For reference, I will use ZXing . Net library from ... The first three INSERT statements are valid because they contain unique int1 column values. The fourth INSERT statement has a missing int1 column value. Because int1 serves as the primary key for the table, the missing value causes the rejection of the whole row. The fifth INSERT statement specifies an int1 column value of 3, but the third INSERT statement previously added a row to the table with this value. Therefore, SSE rejects the row for the fifth INSERT statement because it has a duplicate primary key value. INSERT INSERT INSERT INSERT INSERT T T T T T (int1, (int1, (int1) (bit1) (int1, bit1) VALUES (1, 1) bit1) VALUES (2, 0) VALUES (3) VALUES (1) bit1) VALUES (3,1) Figure 4 32.

The following listing shows the result of running the script in Ch04UsingPrimaryKey.sql. A SELECT statement for all the column values in each row within the table created by the preceding CREATE TABLE statement generates the following output (SELECT * FROM T). The first three INSERT statements succeed. Before the result set for the SELECT statement, you can see error messages returned by SSE. These error messages explain why two of the INSERT statements did not succeed. Msg 515, Level 16, State 2, Line 8 Cannot insert the value NULL into column 'int1', table 'ProSSEAPPSCh04.dbo.T'; column does not allow nulls. INSERT fails.The statement has been terminated. Msg 2627, Level 14, State 1, Line 9 Violation of PRIMARY KEY constraint 'PK__T__145C0A3F'. Cannot insert duplicate key in object 'dbo.T'. The statement has been terminated. int1 bit1 ----------- ----1 1 2 0 3 0 It is common to specify an IDENTITY property for a column with an integer data type that serves as a primary key. The IDENTITY property causes SSE to assign sequential column values starting from a seed value in fixed increments. Although the default seed and increment values for the IDENTITY keyword are both 1, you can override either or both. To change the default seed and increment settings, merely specify IDENTITY(seedvalue, incrementvalue) instead of IDENTITY. When a column has an IDENTITY property setting, users do not have to specify a value for a column during the insertion of a new row because SSE automatically assigns a column value. If you attempt to insert a column value for a column with an IDENTITY property setting, SQL Server rejects the row by default. When you include an IDENTITY property setting for a column serving as the primary key, you do not have to worry about duplicate values because SQL Server automatically specifies sequentially unique values. The next group in the Home tab is called Alignment, and Alignment commands are likewise considered formatting. These enable you to position, and reposition, the data you ve entered in their cells (Figure 4 33): qr code reader c# .net VB . NET QR Code Barcode Scanner DLL - Scan ... - BarcodeLib.com
