使用 MySQL 设置列名中的空格?

To set spaces in column names in MySQL, you can use the concept of backticks. Let's first create a table. The following is the statement of the query −

mysql> create table blankSpacesDemo
   -> (
   -> `Student Id` int NOT NULL AUTO_INCREMENT PRIMARY KEY,
   -> `Student Full Name` varchar(100)
   -> );
Query OK, 0 rows affected (0.51 sec)

The following is the query to insert some records in the table using the insert command-

mysql> insert into blankSpacesDemo(`Student Full Name`) values('John Smith');
Query OK, 1 row affected (0.16 sec)

mysql> insert into blankSpacesDemo(`Student Full Name`) values('Carol Taylor');
Query OK, 1 row affected (0.14 sec)

mysql> insert into blankSpacesDemo(`Student Full Name`) values('David Miller');
Query OK, 1 row affected (0.15 sec)

The following is the query to display all the records in the table using the select statement:

mysql> select `Student Id`,`Student Full Name` from blankSpacesDemo;

The following is the output showing spaces in the column name "Student Full Name" -

+------------+--------------------+
| Student Id | Student Full Name  |
+------------+--------------------+
| 1          | John Smith         |
| 2          | Carol Taylor       |
| 3          | David Miller       |
+------------+--------------------+
3 rows in set (0.00 sec)

Optimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata.

Best practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.
