He Mahi Kotahi, he Papa Whakaeke Whānui
Whakaarohia tēnei: kei te hanga koe i tētahi ratonga iti e tukatuka ana i ngā rēhitatanga kaiwhakamahi. I tētahi wāhi o te tukanga mahi, ka tapahia e koe tētahi wāhitau īmēra mā te whakamahi i taupū_roto i roto i te SQL hei tiki i te rohe. He ātaahua, he poto, ā, he pai te mahi i roto i te whakaaturanga. Kātahi, i te wā whakaputa, ka tīmata ngā rangitaki ki te whakakī i ngā ingoa katoa me ngā rohe īmēra i roto i te tuhinga noa, he turuturu tūpono mai i tētahi karanga SQL āhua kore kino.
Koinei te raruraru: Taupū_aho-iti SQL Ko tētahi o ngā mahi aho i roto i te SQL e āhua haumaru ana kia whakamahia rā anō ki te wāhi hē. I roto i ngā taupānga SaaS maha-kaitākaro, i ngā pūnaha rānei e whakahaere ana i ngā raraunga tairongo, ka taea e te whakamahi hē te whakaatu i ngā tuhinga tūmataiti, te tuku rānei i te pikinga mana me te kore e whakaoho i ngā matohi mārama. I roto i ngā taiao tino nui, inā koa ko ngā tūāpapa maha-kaitākaro e taea ai e te uiui kotahi te mahi ki ngā kiritaki maha, ka puta he hapa arorau wehewehe iti i roto i taupū_roto i roto i te SQL ka arahi pea ki te whakawāteatanga raraunga whakawhiti-kairīhi, ka turuturu ngā mōhiohio i waenga i ngā huinga raraunga takitahi.
Te Mārama ki te SUBSTRING_INDEX i roto i te Waehere Tuturu
I roto i te MySQL me te MariaDB, e toru ngā tautohe a te SQL substring_index: te aho hei tukatuka, he wehewehe, me te tatau. Ka whakahokia mai he wāhanga o te aho i mua atu, i muri rānei i taua wehewehe.
He mea whakamahi noa i roto i ngā patai tono hei wehewehe tere i ngā uara hanganga kua rongoatia ki roto i te āpure kotahi, hei tauira, te wehewehe i tētahi īmēra ki te ingoa kaiwhakamahi me te rohe, te tango i tētahi roherohe mai i tētahi URL, te wehe rānei i tētahi kupumatua mai i tētahi kī hiato. He maha ngā wā ka whiriwhiria e ngā kaiwhakawhanake te substring_index i roto i te SQL i te wetewete taha-tono nā te mea he mea whakararuraru.cise, ka karo i ngā tukatuka tāpiri i waho o te pātengi raraunga, ā, ka taea te whakamahi tika i roto i ngā tātari, ngā hononga, me ngā mahi whakarōpū.
tauira: Te tango i te ingoa kaiwhakamahi me te rohe mai i te īmēra
MAI i ngā kaiwhakamahi;
Ko ngā whakamahinga noa mō te substring_index i roto i te SQL ko:
- Te tango i ngā ingoa kaiwhakamahi mō ngā karere powhiri
- Te whakamana i ngā rohe īmēra ki ngā rārangi whakaae/whakakahore
- Te whakarōpū i ngā kaiwhakamahi mā te rohe i roto i ngā patai tātaritanga
no te mea Taupū_aho-iti a SQL he concisHe tere, he tere hoki te whakamahi a ngā kaiwhakawhanake i roto i ngā mahi aho i roto i te SQL mō te tātari, te whakamana, te tuku pūrongo rānei. Ka tīmata te raruraru ina he hihiri ngā wehewehe, ngā tatau rānei, ā, ka ahu mai i te whakauru a te kaiwhakamahi.
Te Wāhi e Pakaru ai te Haumarutanga – Substring_index i roto i te SQL
E toru ngā tauira mōrearea matua e huri ana taupū_roto i roto i te SQL ki roto i tētahi taunahatanga, inā koa i roto i ngā pūnaha maha-kainoho, ngā pūnaha nui-tēpu rānei:
Te nui rawa o te whakaaturanga raraunga
I roto i tētahi pātengi raraunga tiritahi, ka taea e tētahi hapa takitahi, e tētahi tatau wehewehe hē rānei te turuturu i ngā taipitopito tairongo mai i ētahi atu kairēti, i ngā kaiwhakamahi kāore anō kia pāngia.
I roto i tētahi CRM maha-kairēti, ka taea e tēnei te whakaatu i ngā ingoa katoa o ngā kiritaki mai i ētahi atu kamupene i roto i te CSV kaweake a te kairēti.
Tāurunga kore, he rānei te hanganga
Mena kei te ngaro te wehewehe, kei te kore rānei te tāuru, Taupū_aho-iti a SQL ka taea te whakahoki i te āpure katoa. I roto i ngā pūnaha nui, ka taea e tēnei te whakaatu i ngā ID ā-roto, ngā raraunga honohono, ngā uara patuiro rānei kāore i te whakaarohia kia kitea i waho.
Te urunga kore whakamanatanga i roto i ngā hononga, i ngā uiuinga iti rānei
I roto i ngā tatūnga maha-kairēti, ka taea e te whakamahinga koretake o ngā mahi aho i roto i te SQL mō te whānuitanga o te kairēti te pakaru i te wehenga:
If tohutoro_kaihoko Ki te kore e ōrite te whakatakotoranga, e whakahaerehia ana rānei e te kaiwhakamahi, ka taea e te Kairēti A te tiki i ngā ota a te Kairēti B. I roto i ngā pūnaha utu, i ngā tūāpapa hauora rānei, ka noho tēnei hei takahi tika i ngā kaupapa here wehewehe raraunga.
Tauira mōrearea maha-kainoho: Whakaarohia he tūāpapa nama SaaS kei reira tohutoro_kaihoko e whakakōwae ana i te ID kairihi i mua i te tohu pōwhiri (ID OTA-KAIHOKO). Mena ka tukuna e te kaiwhakamahi kino he tohutoro ota me te ID o tētahi atu kairēti engari he nama ota tika, ā, ka whakamahia e te hononga taupū_roto i roto i te SQL ki te kore he manatoko, ka taea e rātou te uru atu ki ngā raraunga nama nō tētahi whakahaere rerekē rawa atu.
Ngā Wāhanga Whakaeke Tuturu i roto i CI/CD me te Waehere Pūtake Tuwhera
Tuhinga o mua Taupū_aho-iti SQL ehara i te hapa whakawhanake-tauira anake; ka puta mai i roto i:
- Ngā uiui ORM me ngā wehewehe hihiri
- Ngā tukanga kua rongoatia i roto i ngā monomai pūtake-tuwhera
- SQL ā-roto e hono tika ana i ngā tawhā tono
Te tae atu o te waehere haumaru kore ki te whakaputanga:
Ki te kore he arowhai aunoa mō ngā mahi aho morearea i roto i te SQL, ka kore e kitea ēnei mōrearea, ā, ka tae atu ki te mahi whakaputa, ka turuturu pea ngā raraunga tairongo mai i te rā tuatahi.
Te kimi i roto i SAST/CI-CD
Ko te huarahi haumaru ki te whakahaere i ngā mea mōrearea taupū_roto i roto i te SQL ko te aukati i ngā tauira i mua i te hanumitanga.
Me hopu e ngā ture kimi:
- Tuhinga o mua Taupū_aho-iti SQL me ngā wehewehe, ngā tatau rānei mai i ngā tawhā tono
- Ngaro ana te whakamana wehewehe
Tauira ture iti rawa:
Pipeline taahiraa:
Mā te matawai i ngā mahi aho haumaru kore i roto i te SQL i te wā tirotiro PR, ka tangohia e koe te whakapae mai i te arotake waehere.
Ngā Rautaki Whakaiti mō ngā Kaiwhakawhanake
Te hopu i te whakamahinga mōrearea o Taupū_aho-iti SQL He pai te whakamahi i ngā arotakenga, i ngā matawai rānei, engari ko te tino wikitoria ehara i te whakaurunga mai i te tuatahi. He maha ngā aituā haumarutanga ka puta mai nā te mea ka whakawhirinaki ngā kaiwhakawhanake ki ngā pokatata kua mōhiotia, me te kore e whai whakaaro ki ngā take taha.
Anei me pēhea te ārai i ngā raruraru i te wā e mahi ana koe me taupū_roto i roto i te SQL ngā mahi aho rite rānei i roto i te SQL:
Whakamanahia ngā tūranga wehewehe i mua i te whakatinanatanga
Kaua e whakaaro noa kei te noho te wehewehe, ā, kei te wāhi tika. I roto i ngā pūnaha maha-kainoho, mā te wehewehe ohorere kotahi i roto i tētahi tohu ka taea te whakatuwhera i te urunga ki ngā raraunga a tētahi atu kainoho.
- Tirohia te roa o te putanga e tumanakohia ana
Whakatakotoria he rohe haumaru. Mena he poto rawa, he roa rawa rānei te hua o te aho iti, whakaarohia he kore mana. - Whakakorehia, whakakōwaea hoki ngā raraunga i mua i te whakamahinga
Tangohia ngā wehewehe tinihanga mai i te tāuru i tukuna mai e te kaiwhakamahi i mua i tōna taenga atu ki te SQL - A ape i taupū_roto i roto i te SQL i roto i te arorau haumarutanga-tino nui
Kaua rawa e whakamahia mō ngā tirotiro whakaaetanga, te wehe i te kairēti, me tetahi mea rānei e whakahaere ana i te urunga atu ki ngā raraunga tairongo. Ehara te wetewete i te rohe haumarutanga - Nukuhia te tātaritanga ki te paparanga taupānga. Mā te arorau taha-tono ka pai ake tō mana whakahaere mō te whakamana, te whakahaere hapa, me ngā whakamātautau wae.
Mā te whakamahi i ngā mahi aho i roto i te SQL hei ara waehere kāore i te whakawhirinakihia, ka whakaitihia e koe te radius pahūtanga o tētahi hapa arorau.
Whakaurunga ki ngā Utauta Haumarutanga
Ahakoa ngā tīma pūkenga, kāore e taea te whakawhirinaki anake ki ngā arotake ā-ringa; he tauira mōrearea pērā i te kore haumaru. Taupū_aho-iti SQL kāore pea e taea te whakamahi, inā koa i roto i ngā pūtake waehere nui, i te wā rānei e mahi ana me te waehere tuatoru.
He aha me whakauru ai ngā taputapu pēnei i a Xygeni:
- E kapi ana i te waehere tuwhera me te waehere rangatira: kia kore ai e huna ngā ngoikoretanga i roto i ngā mōkihi kaihoko, i ngā kōwae tawhito rānei.
- Ka kitea ngā tauira mōrearea i roto i ngā hōtuhi SQL me te waehere tono: te kimi taupū_roto i roto i te SQL e kore e whakamahia kinotia ahakoa kei roto i ngā aho i roto i a Python, Java, Node.js rānei.
- Ka whakauru tika ki roto CI/CD pipelines: ka rahua aunoa ngā hanganga mēnā he haumaru ngā mahi aho i roto i te SQL ka kitea.
- Ka whakarato tohutohu whakatikatika mahi: e whakaatu ana i ngā kaiwhakawhanake ko tēhea wāhanga o te patai he morearea, he aha ai, me pēhea te whakatika.
Tauira rerenga mahi me Xygeni i roto i CI/CD haumarutanga:
Matawai haere tonu he mea nui i mua i te whakatinanatanga, ka whakarite kia kore e whakamahia ngā mea mōrearea o taupū_aho-iti sql ka mau i te wā o te whanaketanga tuatahi, tae atu ki ngā whakahoutanga o muri mai, ngā whakatikatika, me ngā huringa whakawhirinakitanga. Ko te tikanga o tēnei huarahi matatau ka whakakorea ngā ngoikoretanga i mua i te taenga atu ki te whakaputa.
Ngā Whakaaro Whakamutunga mā ngā Kaiwhakawhanake – Mō te substring_index i roto i te SQL
Anei te raina o raro:
- Taupū_aho-iti SQL ehara i te mea kino rawa, engari ki te whakamahia kinotia ka huri hei turuturu raraunga puku.
- katoa taupū_roto i roto i te SQL Me whakapae te waea atu i tētahi ara haumaru kia whakamātauria rā anō he haumaru.
- Ka taea e ngā mahi aho katoa i roto i te SQL te noho mōrearea i roto i ngā horopaki e whai tikanga ana ngā rohe raraunga, ngā whakaaetanga rānei; me whakaaro tonu he mea mōrearea pea i roto i ngā taiao tairongo, ahakoa he māmā noa iho, he kore kino rānei.
Ngā mahi whai muri mā ngā tīma whakawhanake:
- Arotakehia tō pūtake waehere mō tetahi whakamahinga o Taupū_aho-iti SQL i roto i ngā hononga, ngā uiuinga iti, ngā arorau whakahaere urunga rānei.
- Tāpiri SAST ture ki te kite i ngā wehewehe hihiri me ngā tāurunga kāore i manatokohia i roto ngā mahi aho i roto i te SQL.
- Nekehia te tātaritanga ki te paparanga tono i nga wa katoa ka taea.
- Whakahaerehia ngā matawai tonu me ngā taputapu pēnei i a Xygeni hei hopu i te whakamahinga morearea i mua i te whakatinanatanga.
Ehara i te mea ko te whakakapi i ngā hapa i muri i te mahi te kaupapa haumaru; engari ko te aukati i te whakauru i ngā hapa ki roto i te tukanga mahi. Mena ka rongoa koe Taupū_aho-iti SQL me ētahi atu mahi aho i roto i te SQL me te tūpato rite ki te whakaurunga kaiwhakamahi mata, ka karohia e koe te huri i tētahi kaiawhina watea hei rārangi tino morearea i roto i tō patai.
