97-2003版本
EXCEL
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=文件位置;ExtendedProperties=Excel 8.0;HDR=Yes;IMEX=1
ACCESS
Provider=Microsoft.Jet.OLEDB.4.0;Data Source=文件位置;JetOLEDB:Database Password=密码;
2007版本
EXCEL
Provider=Microsoft.Ace.OleDb.12.0;DataSource=文件位置;Extended Properties=Excel12.0;HDR=Yes;IMEX=1
ACCESS
Provider=Microsoft.Ace.OleDb.12.0;DataSource=文件位置;Jet OLEDB:Database Password=密码;
【其他说明】
HDR=Yes/NO 表示是否将首行做标题。
IMEX 表示是否强制转换为文本
特别注意
Extended Properties='Excel 8.0;HDR=yes;IMEX=1'
A: HDR ( HeaDer Row )设置
若指定值为Yes,代表 Excel 档中的工作表第一行是栏位名称
若指定值為 No,代表 Excel 档中的工作表第一行就是資料了,沒有栏位名称
B:IMEX ( IMport EXport mode )设置
IMEX 有三种模式,各自引起的读写行为也不同,容後再述:
0 is Export mode
1 is Import mode
2 is Linked mode (full update capabilities)
我这里特别要说明的就是 IMEX 参数了,因为不同的模式代表著不同的读写行为:
当 IMEX=0 时为“汇出模式”,这个模式开启的 Excel 档案只能用来做“写入”用途。
当 IMEX=1 时为“汇入模式”,这个模式开启的 Excel 档案只能用来做“读取”用途。
当 IMEX=2 时为“连結模式”,这个模式开启的 Excel 档案可同时支援“读取”与“写入”用途。

The advantage of multithreading is that it can improve performance and resource utilization, especially for processing large amounts of data or performing time-consuming operations. It allows multiple tasks to be performed simultaneously, improving efficiency. However, too many threads can lead to performance degradation, so you need to carefully select the number of threads based on the number of CPU cores and task characteristics. In addition, multi-threaded programming involves challenges such as deadlock and race conditions, which need to be solved using synchronization mechanisms, and requires solid knowledge of concurrent programming, weighing the pros and cons and using them with caution.

The main reasons why you cannot log in to MySQL as root are permission problems, configuration file errors, password inconsistent, socket file problems, or firewall interception. The solution includes: check whether the bind-address parameter in the configuration file is configured correctly. Check whether the root user permissions have been modified or deleted and reset. Verify that the password is accurate, including case and special characters. Check socket file permission settings and paths. Check that the firewall blocks connections to the MySQL server.

SQL IF statements are used to conditionally execute SQL statements, with the syntax as: IF (condition) THEN {statement} ELSE {statement} END IF;. The condition can be any valid SQL expression, and if the condition is true, execute the THEN clause; if the condition is false, execute the ELSE clause. IF statements can be nested, allowing for more complex conditional checks.
