Чтение Xml Использование T- SQL

/ 05 февраля 2020

Я столкнулся с проблемой. Я пытаюсь разобрать указанный c XML документ. Документ начинается с тега, и внутри этих тегов может быть несколько кандидатов (в моем примере я предоставил 2 из них, но может быть любое количество предоставленных кандидатов.

Также у заявителя может быть несколько теги сохранены, опыт работы и т. д.

Проблема, с которой я сталкиваюсь, не может разобрать XML правильно, я получаю много повторяющихся строк и не могу понять, что проблема в

Я пытаюсь проанализировать данные с помощью CrossApply, и я знаю, что различение значений не является правильным способом.

Может кто-нибудь, пожалуйста, дайте мне знать, как я могу правильно проанализировать данные xml, если я не знаю, сколько претендентов содержится в файле XML?

Кажется, я понял это сам, но мне не удается соединить узлы вместе.

Правильный способ - соединить их вместе, используя псевдоним T (c)

Ниже приведен пример

CROSS APPLY #xmlDataParse ._ xml .nodes ('/ response / заявитель') T (c)
CROSS APPLY T. c .nodes ( «образование») как образование (c)) 

IF OBJECT_ID('tempdb..#XmlApplicant') IS NOT NULL DROP TABLE #XmlApplicant
SELECT T.c.value('applicant_id[1]', 'varchar(500)') AS 'applicant_id'
    ,T.c.value('cv_id[1]', 'varchar(500)') AS 'cv_id'
    ,T.c.value('time[1]', 'varchar(500)') AS 'time'
    ,T.c.value('cover_letter[1]', 'varchar(max)') AS 'cover_letter'
    ,T.c.value('questions_answers[1]/question_1[1]', 'varchar(500)') AS 'question_1'
    ,T.c.value('questions_answers[1]/question_2[1]', 'varchar(500)') AS 'question_2'
    ,T.c.value('questions_answers[1]/question_3[1]', 'varchar(500)') AS 'question_3'
    ,T.c.value('questions_answers[1]/answer_1[1]', 'varchar(500)') AS 'answer_1'

    ,Education.c.value('date_from[1]', 'varchar(500)') AS 'date_from'
    ,Education.c.value('date_till[1]', 'varchar(500)') AS 'date_till'
    ,Education.c.value('institution[1]', 'varchar(500)') AS 'institution'
