How to modify table data in SQL Server?

To modify data in a SQL Server table, you can use the UPDATE statement. Here is an example:

UPDATE 表名
SET 列1 = 新值1, 列2 = 新值2
WHERE 条件;

1. Table name: the name of the table for which the data needs to be modified.
2. Specify the names of the columns to be modified in Column 1 and Column 2.
3. New value 1 and new value 2: specify the new values to be set.
4. Condition: Optional WHERE clause used to specify the condition of the data rows to be modified.

Before executing the UPDATE statement, make sure you have sufficient permissions and carefully check and validate the data and conditions to be modified to avoid accidentally altering incorrect data.
