In this issue, the editor will bring you about how to connect and debug the relevant ADO.NET database. The article is rich in content and analyzes and describes for you from a professional point of view. I hope you can get something after reading this article.

ADO.NET database development includes easier design integration, expanded deployment options, more colorful login and personalized services, and better data access and synchronization. This is a better way to study and research, and then we will learn.

If execute_statement uses READTEXT statements to return data, each individual READTEXT statement can return up to 1 MB (1024 KB) of data, or you can use the ADO.NET database with the extension process and insert the data returned by the main thread of the extension process. The output from other threads other than the main thread is not inserted.

Indicates that for ADO.NET databases, execute_statement does not contain extended stored procedures that return text or image columns. This behavior is a change from earlier versions of SQL Server. DEFAULT VALUES forces the new row to contain the default values defined for each column.

INSERT appends new rows to the table. To replace data in a table, you must use DELETE or TRUNCATE TABLE statements to clear existing data before using INSERT to load new data. To modify a column value in an existing row, use UPDATE. To create a new table and load data for it in one step, use the INTO option of the SELECT statement.

Table variables can be accessed like regular tables within their scope. Therefore, you can use the table variable just as you would add a row to a table in an INSERT statement. For more information about the ADO.NET database, see table. The four-segment name established by the OPENDATASOURCE function as part of the server name can be used as a table source, which can appear in all locations in the INSERT statement where the table name is displayed.

Columns created using the uniqueidentifier data type store 16-byte binary values in a special format. Unlike identity columns, SQL Server does not automatically generate values for columns with uniqueidentifier data types. During the insert operation, variables with the uniqueidentifier data type and some string constants can be used for uniqueidentifier columns (these string constants are in the form of: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx, 36 characters.

This includes that the hyphen ADO.NET database is a hexadecimal number in the range of 0-9 or amurf. ). For example, for an ADO.NET database variable or column, 6F9619FF-8B86-D011-B42D-00C04FC964FF is a valid value. Use the NEWID () function to get the ID (GUID) of the global *.

This is how the relevant ADO.NET database is connected and debugged. If you happen to have similar doubts, you might as well refer to the above analysis to understand. If you want to know more about it, you are welcome to follow the industry information channel.
