      Description

      It seems that however cpimport imports data from a select insert is having trouble when the table has at least 2 fields with more than one backslash (and ending with a backslash). The error can be reproduced with the SQL below:

      CREATE TABLE IF NOT EXISTS data.example_columnstore_table (  
            `Blah` VARCHAR(255) NOT NULL      
      ) ENGINE=columnstore;
      		 
       
      		 
      CREATE TABLE IF NOT EXISTS data.example_innodb_table (  
            `Blah` VARCHAR(255) NOT NULL      
      ) ENGINE=INNODB;
      		 
       
      		 
      INSERT INTO data.example_innodb_table (`Blah`) VALUES ("test \ ing \\");
      		 
      INSERT INTO data.example_innodb_table (`Blah`) VALUES ("foo");
      		 
      INSERT INTO data.example_innodb_table (`Blah`) VALUES ("test \ ing \\");
      		 
      INSERT INTO data.example_columnstore_table (`Blah`) SELECT `Blah` FROM data.example_innodb_table;

      It looks like the last value isn't properly escaped and so expects more data to be inserted, but that may be a misunderstanding of what it's doing on my part. Either way, it fails and locks the table.
