SQL: Creating/Dropping table

• Create TableCREATE TABLE “lab"."tblpeople1" ("peopleId" int4 DEFAULT 0 NOT NULL,"fName" varchar(70),"mName" varchar(70),"lName" varchar(100),PRIMARY KEY ("peopleId"));

• Drop tableDROP TABLE “lab".“tblpeople1";

Modifying table data

INSERT INTO "lab"."tblpeople" VALUES ('1', 'Thomas', '\\N', 'Hunt');

SELECT * FROM "lab"."tblpeople";

UPDATE "lab"."tblpeople" SET "lName" ='Hunt' WHERE "peopleId" = 1;

DELETE FROM "lab"."tblpeople" WHERE "peopleId" = 1;

Altering tables

ALTER TABLE "lab"."tblpeople" ADD "nickName" VARCHAR(70);

ALTER TABLE "lab"."tblpeople" DROP "nickName";

QueriesSELECT * FROM "lab"."tblpeople" LIMIT 3;

SELECT * FROM "lab"."tblpeople" WHERE "lName" = 'Hunt';

Sorting and GroupingSELECT * FROM "lab"."tblpeople" ORDER BY "fName", "lName";
