tool to generate class from database table c#

C # core syntax-Reflection (reflection type, method, constructor, attribute, configurable and scalable, complete reflection encapsulation of Database Class ), Reflection is. NET. through reflection, you can obtain information about members and members of every type (including class, structure, Delegate, interface, and

C ++ Class Library: OTL connects to the MySQL ODBC database (insert, update, select) and otlodbc I. Introduction OTL is a pure C ++ universal database connection template library, can support a variety of popular databases, such as Oracle, Sybase, MySQL, PostgreSQL, Enterpri

C # Use the SqlBulkCopy class to batch copy data to the database, Recently, the company needs to optimize the import. Because the previous method was to generate an Insert statement and Insert the statement into the database, the data volume is fine when the data volume is s

The Oracle Database operations class implemented in this article for C # can perform many common Oracle database operations, including the underlying database connection, closing the connection, outputting the recordset, executing the SQL statement, returning a dataset with

Let's talk about the reason for writing this help class. Previously, when writing project code, we found that a lot of code is required to read database data to the List set or to add or update parameterized SQL statements, especially when there are many table fields, it is very obvious that it is not only a physical activity, but also a low programming efficienc

expression follows the standard SQL conventions used to sort the columns, such as LastName ASC, FirstName ASC.If you make multiple calls to the Select method of a DataTable, you can first create a DataView for the DataTable to improve performance. Create DataViewThe rows in the table are indexed. The Select method then uses the index, which significantly shortens the time it takes to generate the query res

Create a project 1. Add a table named rwtest to the SQL Server MYTest database. The table field is set as follows: A. uniquely identifies the field name is "ID"and the type is Int. B. a field of type VarChar called "Description" with a field length of c. A field of type varbinary (

1, SQLDMO SQLDMO is the ideal way to manipulate SQL Server, and you can consider this approach if your database is SQL Server. Using SQLDMO in C # requires adding SQLDMO references, and then using SQLDMO in the current file, that is, SQLDMO can be used. The SQLDMO object model can be obtained in the help of SQL Server. Copy Code code as follows: private void Gettabels_dmo (string strservern

Use C #'s powerful exception and error message to determine whether the data table in the database exists! You can use ADO. Net to check whether a data table with a name exists in the database. However, most of the information I found is the method of using the COM component

Parameters.addrange (Parameters); Mysqldataadapter MDA = new Mysqldataadapter (cmd); The data that is queried is present in a DataTable, and a DataTable can be understood as a virtual table, a behavior in a DataTable, a record, a

C # display the alias of the GRID field. Use the SQL database table and field description in MS, We can see that most of the existing ERP systems display Chinese field names to users. If ERP is maintained, we will find that all the background databases use English field names, in this case, a field name alias conversion process is required. I have tried to use th
