How to store excel data into the database, how to write the code

Answer 1

Storing Excel data into a database usually requires the use of programming languages (such as Python, Python, etc.) and corresponding database management tools. Here are some basic steps:

1. Use a programming language to connect to the database and retrieve the required tables and fields.

2. Use an Excel read-write library (such as Apache POI in Java or pandas in Python) to read the Excel file as an object and get the cell value.

3 Store the cell values in the database table.

4. If necessary, you can query, filter, sort, and other operations on the data.

Here are some basic examples of the code:

```java
import javasql*;
import javaio*;

public class ExcelToDatabase {
public static void main(String[] args) throws IOException {
String url = jdbc:mysql://localhost:3306/mydatabase;
String username = myuser;
String password = mypassword;

try {
Connection conn = DriverManagergetConnection(url username password);
PreparedStatement stmt = connprepareStatement(SELECT * FROM table_name);

//Read the Excel file
BufferedReader in = new BufferedReader(new FileReader(new File(args[0])));
String line;
while ((line = inreadLine()) != null) {
stmtsetString(1 line);
stmtexecuteUpdate();
}

inclose();

//Close the database connection
stmtclose();
connclose();
} catch (SQLException e) {
eprintStackTrace();
}
}
}
```

The above code reads the data in an Excel table named `table_name` into the mysoid database and obtains all the rows of data.

Similarly, the pandas library in Python provided similar functions. The following is a Python code example:

```python
import pandas as pd
import javasql*;

#Connecting to the database
df = pdread_excel(filexlsx)

#Write data to the database
sql = INSERT INTO table_name (column1 column2 column3) VALUES (%s %s %s)
conn = getConnection()
connprepareStatement(sql)
dfto_sql(:table_name conn if_exists=replace)

#Close the database connection
connclose()
```

The above code writes the data in an Excel table named `table_name` into the mysmysticism database and substitutes the original data table.

Please note that these are just some basic steps and sample code. The specific implementation method may vary depending on the programming language, database type, data table structure, and other factors. At the same time, in order to ensure the accuracy and completeness of the data, please ensure that the original data sheet and operation steps are carefully checked before operating the database.
