     DECLARE p_startIndex int ; 
     DECLARE p_suffix VARCHAR(50) ; 
     DECLARE p_voucherNo VARCHAR(50) ; 
     DECLARE p_prefix1 VARCHAR(50) ; 
     DECLARE p_suffix1 VARCHAR(50) ; 
      IF (((SELECT COUNT(suffixPrefixId)FROM tbl_SuffixPrefix WHERE (yearId = p_yearId) AND (voucherType = p_voucherType)))<>0);

         SET p_startIndex=(SELECT startIndex FROM tbl_SuffixPrefix WHERE (yearId = p_yearId) AND (voucherType = p_voucherType)); 
         SET p_startIndex=p_startIndex-1; 

          IF p_voucherType='Sales Invoice' 
           then SET p_voucherNo=(SELECT ifnull(MAX(voucherNo+1),1) FROM tbl_SalesMaster WHERE((suffixPrefixId = (SELECT suffixPrefixId FROM tbl_SuffixPrefix WHERE (yearId = p_yearId) AND (voucherType = p_voucherType)))

Answer 1

獨立COUNT（suffixPrefixId）FROM爲COUNT（suffixPrefixId）FROM

Answer 2

嘗試從以下if語句刪除分號：

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

Answer 3

嘗試把你的DECLARE statements權之後BEGIN：

DECLARE僅在BEGIN ... END複合語句中被允許，並且必須在任何其他語句之前開始。
