An sql_name is either a standard SQL name starting with a Latin alphabet character and that contains only Latin characters, numbers and/or underscores, or a square-bracketed string. The right square bracket is escaped by doubling.
Examples:
| String to pass | sql_name |
| MySQLName_2 | MySQLName_2 |
| My non-standard !&^#%!&#% name | [My non-standard !&^#%!&#% name] |
| [already-bracketed name] | [[already-bracketed name]]] |
| name with brackets[] inside | [name with brackets []] inside] |
