Reo Uinga Whakaraupapa

Ko te tīmatanga kia ako pehea e hanga waea katoa e pā ana ki te tahi mea. He tino he maha nui o ngā huarahi ki te whakarite rapu ki etahi raraunga e te hunga e wātea ana i te pūnaha mōhiohio. Kotahi pea - he reo rapu hanganga (English SQL whakarāpopototanga). āhei te reira ki a koutou te hanga pātai poto mo te kōwhiringa o te mōhiohio e tika ana. Otiia ka taea e te mahi i te reira anake ki papa e rua-ahu, i hoatu mua he maha o titauraa ano.

Ka taea e ara e koe te whakapūtā he maha o ngā whakaritenga atu, ahua, e hāngai ana i runga i te tetahi huru, rōpū noa ranei. Hoki moni iti o raraunga e tika ana taka tino pai.

He aha e hiahia ana koe MySQL?

A ki tenei MySQL? He aha te mea katoa e pā ana ki? Pehea i taea e matau te kaipānui tino tere-witted, he mea he toronga motuhake o te hanganga reo rapu. Ko te wahi e te whakamahia ai? Ko te take i te mea he putanga motuhake mō te whakamahi i roto i te wāhanga hōtaka tukutuku tenei. reo noa Whakaraupapa Uiui hangaia roa ki te mahi i runga i te rorohiko, i te MySQL - i runga i te tukutuku-wāhanga.

He aha te mea te rerekētanga i waenganui i MySQL me SQL

Ko te te rerekētanga i roto i te wāhanga tono, me te rerekētanga matua ko. Ko reira e etahi rerekētanga tukanga. Na, i mua ia koutou mahi ki te pātengi raraunga mā te whakamahi i MySQL uiui, e hiahia ana koe ki te uru. Ae, ka mahi MySQL ano te, ki te hoatu i te reira oangé, e kore e taea. Na reira, whakamahia nuitia kotahi reo papatono atu (te nuinga PHP, ahakoa ka taea e koe te whakatau i te kaihoahoa te hanga i te hononga i huaina e ko MySQL tūmau).

He aha te mea he tono?

Na, ka whakahoki tatou te pātai «MySQL - e ko," i mua i puta ki nga hapa taea e taea puta i tuhi hōtaka, kia whai whakaaro te maha o nga mea: e pera tono, tepu pātengi raraunga me ngā pūkete. Kia tīmata te ki te rapu: he poto i runga i te ihirangi o te karere ā i runga i te whakarato o ngā raraunga ratou, a me i roto i ngā mōhiohio e pā ana ki te wahi ki te titiro hoki a ratou, me nga kupu matua i nei e te rapu kia kawea i roto i. I roto i te tikanga, i reira ki te titiro, kia kore raruraru. Na e te aha kupumatua? Ranei pehea maha taea kitea e koe i te matua? Ki te wehewehe i te raraunga e tika ana ki te tono ahurei parau tumu mōhiohio. Ka taea e ratou te mahi kia rite ki te tau whaiaro ranei te tahi atu raraunga. Engari whakamahi pai tonu te Rorohiko raihana.

He aha te mea he pātengi raraunga?

Kei hea te te raraunga e penapena e MySQL uru? O te akoranga, i roto i te pātengi raraunga! I roto i te MySQL, he ratou rua-ahu tepu e kei roto i te kōrero e tika ana. Ai raraunga tāutuhia e te uara e kia tika ki te tīwae i roto i te pātengi raraunga. Na kua tapiritia te mōhiohio i runga i ia kaupapa hou ki te hanga i te aho hou. kia roto he maha o nga papa i roto i te pātengi raraunga (ngā mutunga), engari ka pā te pātengi raraunga te rahi me te tere o ngā raraunga whakautu. Ko te aroaro koutou mahi ki te pātengi raraunga, me hanga e koe tino e reira he tautoko hoki te pūmanawa e tika ana, me te Tūmau MySQL ka taea ki te tīmata. Ahakoa Tei mea katoa i konei i runga i nga tikanga tuatahi - ki te kei te mahi koe i runga i te hautū utua, kua kitea tata tonu nga mea katoa. Otiia me i tukua e koe te tūmau, mo e Me ki te mahi i te wahanga, MySQL pātengi raraunga, me te kore e taea te mahi tika e tika ana ki te meka i reira he kahore pūmanawa e taea ki te whakamāori i te raraunga.

He aha te mea he tepu?

Ripanga, rite kua whakahuatia, tenei taputapu, e pupuru ana i nga raraunga e tika ana. He aha ngā ratou? A, no te te hanga i te tepu, kia mohio ki te tohu e pātengi raraunga e riro te reira. He āhuatanga i reira te tīariari tepu e ratou, kaua raruraru - no te mea o te meka i hangaia te nuinga o taputapu pūmanawa e kia ka taunekeneke ratou ki etahi hōtaka.

Me pēhea te ki te titiro ko te tikanga he tepu MySQL? E ratou tīwae mōhiohio (o te tetahi momo o raraunga) me te raupapa i roto i nei te rongoa ngā mōhiohio i runga i ia kaupapa. Ki te raupapa tonu anake - i reira ko te kaupapa hou - tāpiri he rarangi hou (mā te tango i te nekehia atu te reira). Ki te tīwae o iti uaua. Ko te meka e taea whai i te tīwae kotahi, kotahi anake te momo raraunga. Na, ki te kawea te mahi i roto i ki te tīwae tau, tuhituhi koutou e kore e taea e te kuputuhi e i roto i reira. He momo o ngā momo, i reira e he torutoru rawa (e pā ana ki te 30, i unu ki te tuhinga motuhake kē).

He aha te mea te record?

Na tino tata i mua i neke i runga i ki nga hapa e kia puta i roto i te whakamahi o MySQL, - tuhi. Me whai ia lekooti (rarangi ranei) he pūtāutu ahurei e taea ki te titiro hoki reira i roto i te ripanga papa maha ranei. Pea e kore he whāiti tona roa, engari mo te ngāwari mātakitaki i roto i te aratau "ā-ringa" haere ki te mau mai i roto i te puka "noa". Ko te ngako o te whakaiti taua ko e kua pakaru te lekooti ki te maha mongamonga me whakanohoia i roto i ngā ripanga rerekē. Ahakoa tenei wehenga, he reira taea ki te hoatu tahi whakawhetai ki te pūtautuhi ahurei. Sense actuation puka noa ko ki rōpū te mōhiohio i runga i te taonga i runga i te pūtake o te tahi mea i roto i te noa. Hei tauira, ka taea te hanga i te whare pukapuka tepu "tangata", "Pukapuka" me "rangitaki". Ahakoa i roto i te mahi i taea te whakatinana reira me kotahi tepu ki tetahi urunga, ka i roto i taua i te mōhiohio e tika ana katoa.

hapa pea ka whakamahi i

inaianei taea e koe te haere ki te kaupapa №2. I te mea he aha i reira he hape? I roto i te nuinga o te wā, i roto i te katoa kupu te take tangata. Ka taea e waiho he hapa māmā kua tomo e ki te waehere i te whakatakotoria reira, hē haaputuhia uiui ranei tenei:

1. Ki te reira te mea he raruraru te hono ki te pātengi raraunga, me tirohia e koe tona tapatahi, me te te kōnae tono: Ka taea te hoatu te reira i te ingoa he, ranei kupuhipa pātengi raraunga ki reira. Mahalo, puta MySQL hapa karere no o te kore o te whakanoho i te taputapu pūmanawa, e kia hono ki te pātengi raraunga, me te ki te whakarato pānui i te mōhiohio.
2. A, no te tono raraunga i tepu Me ki te tango i te tiaki o-te kounga tiketike wetemuna o ngā raraunga, me te whakataka i te whakawhiti o ngā mōhiohio i te tūmau MySQL ki a koutou. Ka rite ki kua whakahuatia i runga ake, ka rite ki te tikanga, whakamahia MySQL te i roto i te tautoko o "takawaenga", pera ka kore kino e takina ki te taputapu patuiro ki ranei mai te raraunga e hiahiatia ana i te katoa. Ki te haere mai ratou, engari e kore koe e taea e te whakamahi ratou - te auraa mahi i roto i wetemuna te raraunga riro. I roto i tenei take, he mea e minaminatia ki te tamata i te kōwhiringa katoa mo kaimahi, tīmata ki te pukapuka mahi iti. Kia mahara te reira, rawa te hunga e tika timata ki te taa i te hötaka e ko he wāhi i reira faatiti'aifarohia mea katoa te mahi, me te hapa MySQL tenei, ka taea e koe te tango koe, ka tamata kōwhiringa taea katoa.
