Soal-soal SQL

1. Membuat database baruCREATE DATABASE `AKADEMIK` ;

2. Membuat table baruCREATE TABLE `MHS` (`NIM` CHAR( 4 ) NOT NULL ,`NAMA` VARCHAR( 12 ) NOT NULL ,`JURUSAN` VARCHAR( 10 ) NOT NULL ,`PRODI` VARCHAR( 10 ) NOT NULL ,`KOTA` VARCHAR( 10 ) NOT NULL ) ENGINE = MYISAM ;

3. Mengubah struktur tableALTER TABLE `mhs` CHANGE `NAMA` `NAMAMHS` VARCHAR( 12 ) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL

4. Memasukkan / menyisipkan dataINSERT INTO `AKADEMIK`.`mhs` (`NIM` ,`NAMAMHS` ,`JURUSAN` ,`PRODI` ,`KOTA` )VALUES ('3.34.09.1.27', 'YUANITA', 'ELEKTRO', 'INFORMATIKA', 'SEMARANG'), ('3.34.09.1.25', 'REYHAN', 'ELEKTRO', 'INFORMATIKA', 'SEMARANG');

5. Menampilkan semua isi tabelSELECT * FROM `mhs` LIMIT 0 , 30

6. Mengubah record dataUPDATE `AKADEMIK`.`mhs` SET `NAMAMHS` = 'REYHANA',`PRODI` = 'INFORMATIKA' WHERE CONVERT( `mhs`.`NIM` USING utf8 ) = '3.34' AND CONVERT( `mhs`.`NAMAMHS` USING utf8 ) = 'REYHAN' AND CONVERT( `mhs`.`JURUSAN` USING utf8 ) = 'ELEKTRO' AND CONVERT( `mhs`.`PRODI` USING utf8 ) = 'INFORMATIK' AND CONVERT( `mhs`.`KOTA` USING utf8 ) = 'SEMARANG' LIMIT 1 ;

7. MENAMBAHKAN FIELD PADA TABEL
