How to wrap lines in mysql

Three ways to break lines in MySQL: Use backslashes (\) to form line breaks in text. Use the CHAR(10) function to insert a newline character. Use the UNION operator to manually wrap lines.

How to wrap lines in MySQL

To wrap lines in MySQL, you can use the following methods:

1. Using backslash()

Backslash(\) allows you to create newlines in SQL statements. Just add a backslash where you want a newline. For example:

<code class="sql">SELECT
  CONCAT(name, '\n'), /* 换行 */
  address,
  phone
FROM customers
WHERE city = 'New York';</code>

2. Use the function CHAR(10)

CHAR(10) The function returns a string containing a newline character. You can add it where you want a line break. For example:

<code class="sql">SELECT
  name,
  CONCAT(address, CHAR(10)), /* 换行 */
  phone
FROM customers
WHERE state = 'California';</code>

3. Using the UNION operator

The UNION operator allows you to merge two or more result sets. You can use this to manually wrap lines. For example:

<code class="sql">SELECT
  name,
  address,
  phone
FROM customers
WHERE city = 'Boston'
UNION
SELECT
  name,
  address,
  phone
FROM customers
WHERE city = 'San Francisco';</code>

It should be noted that the UNION operator will delete duplicate rows. Therefore, if you need to keep duplicate rows, you can use the UNION ALL operator.
