Я преобразовываю хранимую процедуру sql в oracle, но получаю сообщение об ошибке

Question

Следующая моя хранимая процедура. Это дает мне ошибку:

(PLS-00103 (65: 199): PLS-00103: Обнаружен символ "(" при ожидании одного из следующего:.) @%).

Ошибка в этой строке:

v_SQLrecords := 'select distinct FEEDBACKQUESTIONS.FeedbackQuestionId as id,' || p_cols || ' ' || v_SQL || ' order by ' || p_cols || ' ' || p_order || ' OFFSET ' || CAST(p_rowsPerPage AS nvarchar2(500)) || ' * (' || CAST(p_pageNo AS nvarchar2(500)) || ' - 1) ROWS FETCH NEXT ' || CAST(p_rowsPerPage AS nvarchar2(500)) || ' ROWS ONLY'

Пожалуйста, предложите мне.

Answer 1

Вы должны применить кавычку даже к CAST заявлениям.

CAST(p_rowsPerPage AS nvarchar2(500)) должно быть 'CAST(' || p_rowsPerPage || 'AS nvarchar2(500))'

Таким образом, ваша строка ошибки должна быть

v_SQLrecords := 'select distinct FEEDBACKQUESTIONS.FeedbackQuestionId as id,' 
             || p_cols || ' ' || v_SQL || ' order by ' || p_cols || ' ' || p_order 
             || ' OFFSET ' || 'CAST(' || p_rowsPerPage || 'AS nvarchar2(500))'  || ' * (' || 'CAST(' || p_pageNo || 'AS nvarchar2(500))'
             || ' - 1) ROWS FETCH NEXT ' 
             || 'CAST(' || p_rowsPerPage || 'AS nvarchar2(500))'  || ' ROWS ONLY';

Как уже упоминалось в чате, есть и другие ошибки. Это только для первой строки, как вы просили.
