Thanks a lot tastybento. You have explained it very well. People like me will now have answer in the future.

Edit: Thanks a lot. It works! I was thinking that phpmyadmin uses only mysql commands & features to everything including dumping databases. I am sorry I did not give information that I was dumping databases and I was using phpmyadmin. I am hoping this world will have more developers like you 😃

I found the issue: your phpMyAdmin is an old version and does not know how to export JSON databases so the table creation SQL is wrong. For example, here is the table creation SQL from the file you gave me for the Island table:

CREATE TABLE `world.bentobox.bentobox.database.objects.Island` (
  `json` longtext CHARACTER SET utf8mb4 COLLATE utf8mb4_bin DEFAULT NULL
) ;

You can see that it does not make the uniqueId column. That’s why you are getting the error. There is no uniqueId to look up.

The correct SQLmust be like this:

CREATE TABLE `world.bentobox.bentobox.database.objects.Island` (
  `json` JSON, uniqueId VARCHAR(255) GENERATED ALWAYS AS (json->"$.uniqueId"), UNIQUE INDEX i (uniqueId)
);

The version of phpMyAdmin you are using is 4.6.6deb64. JSON support was added in 4.7.0, so you need to upgrade. Latest version is 4.9.5.. Having said that, I do not know for certain if it supports full exporting of JSON enabled databases because there is a still open bug on it here.

If phpMyAdmin doesn’t work, then use the mysqldump command to export the database:

mysqldump -u [username] -p [database-you-want-to-dump] > [path-to-place-data-dump]

for example:

mysqldump -u tastybento -p bentobox > dump.sql

When I did this, the CREATE TABLE sql was correct, for example:

DROP TABLE IF EXISTS `world.bentobox.bentobox.database.objects.Island`;
/*!40101 SET @saved_cs_client     = @@character_set_client */;
/*!50503 SET character_set_client = utf8mb4 */;
CREATE TABLE `world.bentobox.bentobox.database.objects.Island` (
  `json` json DEFAULT NULL,
  `uniqueId` varchar(255) GENERATED ALWAYS AS (json_extract(`json`,_utf8mb4'$.uniqueId')) VIRTUAL,
  UNIQUE KEY `i` (`uniqueId`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_ai_ci;
/*!40101 SET character_set_client = @saved_cs_client */;

If you have a running version of the database then I recommend you use the mysqldump command to copy it to the newer database. Just in case, I cleaned up your file and here’s the fixed version: Bentobox_Caveblock.sql.zip However, I recommend using a proper dump from your working database.

I hope that fixes the problem for you.
