PL/SQL Syntax problems - oracle

Question

I am working on online platform to make an ERD and to get the PL/SQL code of it but I get the following code (see below) but I am not sure if it is PL/SQL.
I need to verify if this code is PL/SQL or not:
CREATE TABLE "CATEGORY" (
"ID" NUMBER(10) PRIMARY KEY,
"THLEVEL" NUMBER(10) NOT NULL
);
CREATE SEQUENCE "CATEGORY_SEQ" NOCACHE;
CREATE TRIGGER "CATEGORY_BI"
BEFORE INSERT ON "CATEGORY"
FOR EACH ROW
BEGIN
IF :NEW."ID" IS NULL THEN
SELECT "CATEGORY_SEQ".NEXTVAL INTO :NEW."ID" FROM DUAL;
END IF;
END;;
CREATE TABLE "REPORT" (
"ID" NUMBER(10) PRIMARY KEY,
"CLIENT" CLOB NOT NULL,
"VERSION" NUMBER(10) NOT NULL
);
CREATE SEQUENCE "REPORT_SEQ" NOCACHE;
CREATE TRIGGER "REPORT_BI"
BEFORE INSERT ON "REPORT"
FOR EACH ROW
BEGIN
IF :NEW."ID" IS NULL THEN
SELECT "REPORT_SEQ".NEXTVAL INTO :NEW."ID" FROM DUAL;
END IF;
END;;
CREATE TABLE "ASSET" (
"ID" NUMBER(10) PRIMARY KEY,
"REPORT" NUMBER(10) NOT NULL,
"IP" VARCHAR2(1000 CHAR) NOT NULL,
"NAME" VARCHAR2(1000 CHAR)
);
CREATE INDEX "IDX_ASSET__REPORT" ON "ASSET" ("REPORT");
ALTER TABLE "ASSET" ADD CONSTRAINT "FK_ASSET__REPORT" FOREIGN KEY ("REPORT") REFERENCES "REPORT" ("ID");
CREATE SEQUENCE "ASSET_SEQ" NOCACHE;
CREATE TRIGGER "ASSET_BI"
BEFORE INSERT ON "ASSET"
FOR EACH ROW
BEGIN
IF :NEW."ID" IS NULL THEN
SELECT "ASSET_SEQ".NEXTVAL INTO :NEW."ID" FROM DUAL;
END IF;
END;;
CREATE TABLE "SOLUTION" (
"ID" NUMBER(10) PRIMARY KEY,
"IMPLEVEL" VARCHAR2(1000 CHAR) NOT NULL,
"DIFFICULTY" VARCHAR2(1000 CHAR) NOT NULL,
"DESCRIPTION" CLOB NOT NULL
);
CREATE SEQUENCE "SOLUTION_SEQ" NOCACHE;
CREATE TRIGGER "SOLUTION_BI"
BEFORE INSERT ON "SOLUTION"
FOR EACH ROW
BEGIN
IF :NEW."ID" IS NULL THEN
SELECT "SOLUTION_SEQ".NEXTVAL INTO :NEW."ID" FROM DUAL;
END IF;
END;;
CREATE TABLE "VULNERABILITY" (
"ID" VARCHAR2(1000 CHAR) PRIMARY KEY,
"ASSET" NUMBER(10) NOT NULL,
"SOLUTION" NUMBER(10) NOT NULL,
"CATEGORY" NUMBER(10) NOT NULL,
"CVE" VARCHAR2(1000 CHAR),
"DATE" TIMESTAMP NOT NULL,
"LOCATION" CLOB NOT NULL
);
CREATE INDEX "IDX_VULNERABILITY__ASSET" ON "VULNERABILITY" ("ASSET");
CREATE INDEX "IDX_VULNERABILITY__CATEGORY" ON "VULNERABILITY" ("CATEGORY");
CREATE INDEX "IDX_VULNERABILITY__SOLUTION" ON "VULNERABILITY" ("SOLUTION");
ALTER TABLE "VULNERABILITY" ADD CONSTRAINT "FK_VULNERABILITY__ASSET" FOREIGN KEY ("ASSET") REFERENCES "ASSET" ("ID");
ALTER TABLE "VULNERABILITY" ADD CONSTRAINT "FK_VULNERABILITY__CATEGORY" FOREIGN KEY ("CATEGORY") REFERENCES "CATEGORY" ("ID");
ALTER TABLE "VULNERABILITY" ADD CONSTRAINT "FK_VULNERABILITY__SOLUTION" FOREIGN KEY ("SOLUTION") REFERENCES "SOLUTION" ("ID");
CREATE TABLE "EXPLOIT" (
"ID" NUMBER(10) PRIMARY KEY,
"VULNERABILITY" VARCHAR2(1000 CHAR) NOT NULL,
"NAME" VARCHAR2(1000 CHAR) NOT NULL,
"TYPE" CLOB NOT NULL,
"DESCRIPTION" CLOB NOT NULL
);
CREATE INDEX "IDX_EXPLOIT__VULNERABILITY" ON "EXPLOIT" ("VULNERABILITY");
ALTER TABLE "EXPLOIT" ADD CONSTRAINT "FK_EXPLOIT__VULNERABILITY" FOREIGN KEY ("VULNERABILITY") REFERENCES "VULNERABILITY" ("ID");
CREATE SEQUENCE "EXPLOIT_SEQ" NOCACHE;
CREATE TRIGGER "EXPLOIT_BI"
BEFORE INSERT ON "EXPLOIT"
FOR EACH ROW
BEGIN
IF :NEW."ID" IS NULL THEN
SELECT "EXPLOIT_SEQ".NEXTVAL INTO :NEW."ID" FROM DUAL;
END IF;
END;
So is this PL/SQL or is somethin else from Oracle? How this will sound in PL/SQL?

Answer 1

Well that is PL/SQL and it will work in Oracle if you remove the double semi-colon you have on create trigger.

Answer 2

That is NOT PL/SQL. That is DDL (Data Definition Language). Specifically it is Oracle DDL.

Answer 3

These are DDL statements in which we can create, alter tables ,PL/SQL is a Procedural language SQL in which we use DML Statements for any Process.

Answer 4

These are a set of DDL commands and not PL/SQL as such. However if you incorporate these commands in a nice stored procedure or package, it might be termed as PL/SQL (procedural part of it) but not currently in its current shape.
