An error occurred while executing the SQL statement in PHP, but the same statement can be executed in MYSQL.

PHP fails to execute the SQL statement, but the current problem that the same statement can be executed in MYSQL is that some tables in the same database can be queried, and some tables cannot be queried. However, these statements can be normally executed in mysql. In one case, LZ can be checked in PHP and combined into SQL statements. & nbsp; output the generated SQL statement to check if the SQL statement executed by & nb PHP fails, but the same statement can be executed in MYSQL.
