In the output from
SHOW FULL COLUMNS, the privileges are all in one field and in lowercase, for example,select,insert,update,references. InCOLUMN_PRIVILEGES, there is one privilege per row, in uppercase.PRIVILEGE_TYPEcan contain one (and only one) of these values:SELECT,INSERT,UPDATE,REFERENCES.If the user has
GRANT OPTIONprivilege,IS_GRANTABLEshould beYES. Otherwise,IS_GRANTABLEshould beNO. The output does not listGRANT OPTIONas a separate privilege.
The following statements are not equivalent:
SELECT ... FROM INFORMATION_SCHEMA.COLUMN_PRIVILEGES SHOW GRANTS ...
