SQL Import Issues
When importing the provided SQL source code via the menu, two issues were encountered:

Unrecognized Auto-Incrementing Sequence: The GENERATED BY DEFAULT AS IDENTITY clause for the auto-incrementing sequence was not recognized.

Unidentifiable Enum Types: The enumeration types, such as ENUM_LOGS_ENTRY_CATEGORY, could not be created, leading to them being unrecognized.

CREATE TABLE "t_logs" (

"log_id" INTEGER NOT NULL UNIQUE GENERATED BY DEFAULT AS IDENTITY,

"pat_id" VARCHAR(50) NOT NULL,

"entry_category" ENUM_LOGS_ENTRY_CATEGORY NOT NULL,

"operation_type" ENUM_LOGS_OPER_TYPE NOT NULL,

"entry_count" INTEGER NOT NULL,

"created_at" TIMESTAMP NOT NULL DEFAULT NOW(),

PRIMARY KEY("log_id")

);
