There is no such option!
What is your default LIMIT setting? but well .. a couple a 4 GB LONGBLOBS could be 'funny' 🙁
A reasonable proposal, I think, but TEXT (it is not binary!) and BLOB are equally problematic, whereas a BINARY or VARBINARY type is similar to a CHAR and VARCHAR(up tp 255). And even a lot of 64 KB varchars of MySQL 5 can be equally 'funny'. As of MySQL 5 a VARCHAR, a TEXT and a BLOB are all up to 64 KB.
We will discuss if it is possible to turn of BLOBS, MEDIUMBLOBS and LONGBLOBS (and similar TEXTS)
A workaround is to set LIMIT = 0 in preferences and use the RESULT tab.
