[PATCH] COLUMN_CHECK fails on valid decimal data

    XMLWordPrintable

Details

    • 10.1.10

    Description

      Similar to MDEV-8565 , COLUMN_CHECK can fail with valid Decimal values:

      select column_check(column_create('0', '0' as decimal, '1', '0' as decimal));
      		 
      Result: 0 (failed)

      I think the patch for MDEV-8565 simply missed that decimal 0 is also stored in 0 bytes, as in:

      /* Store decimal zero as empty string */
      		 
        if (precision == 0)
      		 
          return ER_DYNCOL_OK;
