Question

当我在显示时在tb_penerimaan中插入1条记录时，出现1条记录

 MariaDB [sijarvis]> SELECT tb_penerimaan.* , tb_pelanggan.nama FROM tb_penerimaan, tb_pelanggan;
+-------------+------------+----------------+----------------+-----------------+----------+------------+-------------+------+-----------+----------------+-------+------------+-------+
| no_servis   | tgl_terima | kode_pelanggan | nama_perangkat | model_perangkat | no_model | keluhan    | kelengkapan | dp   | status    | solusi         | harga | presentase | nama  |
+-------------+------------+----------------+----------------+-----------------+----------+------------+-------------+------+-----------+----------------+-------+------------+-------+

+-------------+------------+----------------+----------------+-----------------+----------+------------+-------------+------+-----------+----------------+-------+------------+-------+

并插入更多记录出现

MariaDB [sijarvis]> SELECT tb_penerimaan.* , tb_pelanggan.nama FROM tb_penerimaan, tb_pelanggan;
+-------------+------------+----------------+----------------+-----------------+----------+------------+-------------+--------+-----------+----------------+-------+------------+-------+

当我更新记录时显示错误

MariaDB [sijarvis]> UPDATE tb_penerimaan SET no_servis='SER00000002',tgl_terima='2019-02-01',kode_pelanggan='PE000002',nama_perangkat='Sharp',model_perangkat='Aquos',no_model='305sh',keluhan='bootloop',kelengkapan='charger',status='Di Servis',solusi='Instal RAM',harga='15000',presentase='15';
ERROR 1062 (23000): Duplicate entry 'SER00000002' for key 'PRIMARY'

当tb_penerimaan中有1条记录时，我可以更新该记录。在tb_penerimaan中有2条或更多记录时，发生错误Duplicate entry 'SER00000002' for key 'PRIMARY'

Answer 1

在当前的Update语句中，您尝试更新所有行。但这是不可能的，因为no_servis必须是唯一的。正确的是

UPDATE tb_penerimaan SET tgl_terima='2019-02-01', kode_pelanggan='PE000002', nama_perangkat='Sharp', model_perangkat='Aquos', no_model='305sh', keluhan='bootloop', kelengkapan='charger', status='Di Servis', solusi='Instal RAM', harga='15000', presentase='15'
WHERE no_servis = 'SER00000002';

在mysql中更新时重复条目
