Answer 1

Отдельные COUNT (suffixPrefixId) FROM в COUNT (suffixPrefixId) ОТ

Answer 2

Попробуйте удалить точку с запятой из следующих if заявление:

IF (((SELECT COUNT(suffixPrefixId)FROM tbl_SuffixPrefix WHERE (yearId = p_yearId) AND (voucherType = p_voucherType)))<>0); 

Answer 3

Попробуйте положить ваши DECLARE statements право после BEGIN:

DECLARE разрешен только внутри составного заявления BEGIN ... END и должен быть в начале, перед любыми другими инструкциями.
