每个表都要实现,为了简化工作,可以用以下的sql批处理来输出你想要得结果。
不用一个一个列去写。
只需要提供表名称tablename,并把print部分修改成你需要的就可以了。
--请设置查询分析器以文本显示结果
--定义变量
declare @tablename nvarchar(50)--表的名称
declare @tableid int --表的id
declare @colname nvarchar(50) --列名
declare @index int
--赋值
set @tablename = 'tablename' -->>>tablename改为你要查询的表名
select @tableid = id from sysobjects where id = object_id(@tablename)
set @index = 0
--定义游标,逐个遍历表的每个列
declare columns_cursor cursor
for select name as 'Column_name' from syscolumns where id = @tableid order by colid
--打开游标
open columns_cursor
fetch next from columns_cursor into @colname
while @@FETCH_STATUS = 0
begin
-->>>这句需要修改成你要的样式即可(增,删,改,查。)
--我的这句是向一个数据控件写数据(用友华表cell)
print 'axCell1.SetCellString(' + cast(@index as nvarchar) + ', j, 0, ds.Tables[0].Rows[i]["' + @colname + '"].ToString());'
set @index = @index + 1
fetch next from columns_cursor into @colname
end
--关闭,释放游标
close columns_cursor
deallocate columns_cursor

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library. Users only need a few simple steps

How to use MySQLi to establish a database connection in PHP: Include MySQLi extension (require_once) Create connection function (functionconnect_to_db) Call connection function ($conn=connect_to_db()) Execute query ($result=$conn->query()) Close connection ( $conn->close())

To handle database connection errors in PHP, you can use the following steps: Use mysqli_connect_errno() to obtain the error code. Use mysqli_connect_error() to get the error message. By capturing and logging these error messages, database connection issues can be easily identified and resolved, ensuring the smooth running of your application.

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

Python is an ideal programming introduction language for beginners through its ease of learning and powerful features. Its basics include: Variables: used to store data (numbers, strings, lists, etc.). Data type: Defines the type of data in the variable (integer, floating point, etc.). Operators: used for mathematical operations and comparisons. Control flow: Control the flow of code execution (conditional statements, loops).

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

C is an ideal language for beginners to learn programming, and its advantages include efficiency, versatility, and portability. Learning C language requires: Installing a C compiler (such as MinGW or Cygwin) Understanding variables, data types, conditional statements and loop statements Writing the first program containing the main function and printf() function Practicing through practical cases (such as calculating averages) C language knowledge
