    Description

      This script:

      SET sql_mode='STRICT_ALL_TABLES';
      		 
      DROP TABLE IF EXISTS t1;
      		 
      CREATE TABLE t1 (a DECIMAL);
      		 
      INSERT INTO t1 VALUES(CAST('' AS DECIMAL));

      returns an error:

      ERROR 1292 (22007): Truncated incorrect DECIMAL value: ''

      This looks wrong.

      I wrote an explicit CAST, so I expect:

      • CAST to return 0 with a warning
      • INSERT to write 0 into the table normally, as I'm actually inserting the CAST result, which is 0.
