This problem occurs when your data table has boolean as the real words such as “true” or “false” because that format is inappropriate for mysql. Mysql only recognizes boolean as 1 and 0 where 0 = false and 1 = true. There are two solutions for that situation. 1. You can upload your dataset in a spredsheet and replace all the values "false" and "true" with 1 and 0. 2. While uploading data into dbeaver just change the type from boolean into any other string type.
