    Description

      The following query works fine:

      PREPARE stmt FROM
      		 
      'WITH t1 AS (SELECT 1)
      		 
      SELECT * FROM t1
      		 
       UNION ALL
      		 
      SELECT * FROM t1'

      When extracting the "1" into a parameter the query fails with error 1064:

      PREPARE stmt FROM
      		 
      'WITH t1 AS (SELECT ?)
      		 
      SELECT * FROM t1
      		 
       UNION ALL
      		 
      SELECT * FROM t1'

      Tested on OSX 10.13.6. MySQL 8 seems to handle this without trouble.
