标签:creat   function   sel   each   tab   func   rom   from   exit   

范例(cnmq001):

原:每次查询都把数据全部查询到临时表后再筛选;

现:查询到临时表的时候,增加可行的筛选条件,再二次筛选临时表的数据,进行优化;

 

1)临时表创建:

PRIVATE FUNCTION cnmq001_cr_tmp()
 
  DROP TABLE cnmq001_tmp 
  CREATE TEMP TABLE cnmq001_tmp(
   nmbc002 LIKE nmbc_t.nmbc002, 
   nmbc002_desc LIKE type_t.chr500, 
   nmbc005 LIKE nmbc_t.nmbc005, 
   nmbcdocno LIKE nmbc_t.nmbcdocno, 
   nmbcseq LIKE nmbc_t.nmbcseq, 
   nmbc006 LIKE nmbc_t.nmbc006, 
   nmbc007 LIKE nmbc_t.nmbc007, 
   nmbc007_desc LIKE nmajl_t.nmajl003,
   nmbcud001 LIKE nmbc_t.nmbcud001, 
   nmbc003 LIKE nmbc_t.nmbc003, 
   nmbc003_desc LIKE type_t.chr80, 
   inamt    LIKE type_t.num20_6, 
   nmbc100  LIKE nmbc_t.nmbc100,
   nmbc101  LIKE nmbc_t.nmbc101,
   outamt   LIKE type_t.num20_6,
   nmbccrtid LIKE nmbc_t.nmbccrtid,
   nmbccrtid_desc LIKE type_t.chr30,
   nmbccrtdt LIKE nmbc_t.nmbccrtdt
  )
  BEGIN WORK #170406-00001#1 放到事务里
   CALL cnmq001_ins_tmp()
  COMMIT WORK 
END FUNCTION

 

2)TIPTOP没有直接的split分割函数,所以走点弯路:

PRIVATE FUNCTION split_itemcount(p_arg1,p_arg2)
    DEFINE p_arg1   STRING
    DEFINE p_arg2   STRING
    DEFINE l_cnt    INT
    DEFINE tok      BASE.StringTokenizer

    #LET tok = base.StringTokenizer.create(p_arg1,p_arg2)  
    LET tok = base.StringTokenizer.createExt(p_arg1,p_arg2,"",TRUE)  
    LET l_cnt = tok.countTokens()  
    RETURN l_cnt

END FUNCTION

 

PRIVATE FUNCTION split(p_arg1,p_arg2,p_arg3)
    DEFINE p_arg1   STRING
    DEFINE p_arg2   STRING
    DEFINE p_arg3   INT
    DEFINE l_cnt    INT
    DEFINE l_idx    INT
    DEFINE l_retstr STRING
    DEFINE l_str    STRING
    DEFINE tok      BASE.StringTokenizer
    
    INITIALIZE l_retstr TO NULL
    #LET tok = base.StringTokenizer.create(p_arg1,p_arg2)  
    LET tok = base.StringTokenizer.createExt(p_arg1,p_arg2,"",TRUE)  
    LET l_cnt = tok.countTokens()  
    IF (p_arg3 <= 0) OR (l_cnt <= 0 ) OR (p_arg3 > l_cnt) THEN  
        LET l_retstr = NULL  
    ELSE  
        LET l_idx = 1  
        WHILE tok.hasMoreTokens()  
            LET l_str = tok.nextToken()   
            IF l_idx = p_arg3 THEN  
                LET l_retstr = l_str  
                EXIT WHILE  
            END IF  
            LET l_idx = l_idx + 1  
        END WHILE  
    END IF  
    RETURN l_retstr  

END FUNCTION

 

3)本人愚笨,试了几种方法,最后只能通过系统组合出来的条件,进行分割,再重组成自己所需的条件,用在临时表的查询上:

PRIVATE FUNCTION cnmq001_ins_tmp()
DEFINE l_sql STRING
DEFINE l_nmch006      LIKE nmch_t.nmch006
DEFINE l_nmcq006      LIKE nmcq_t.nmcq006
DEFINE l_nmck042      LIKE nmck_t.nmck042
DEFINE l_apde010      LIKE apde_t.apde010
DEFINE l_nmbb025      LIKE nmbb_t.nmbb025
DEFINE lr_tmp RECORD 
      nmbc002 LIKE nmbc_t.nmbc002, 
   nmbc002_desc LIKE type_t.chr500, 
   nmbc005 LIKE nmbc_t.nmbc005, 
   nmbcdocno LIKE nmbc_t.nmbcdocno, 
   nmbcseq LIKE nmbc_t.nmbcseq, 
   nmbc006 LIKE nmbc_t.nmbc006, 
   nmbc007 LIKE nmbc_t.nmbc007, 
   nmbc007_desc LIKE nmajl_t.nmajl003,
   nmbcud001 LIKE nmbc_t.nmbcud001, 
   nmbc003 LIKE nmbc_t.nmbc003, 
   nmbc003_desc LIKE type_t.chr80,

   nmbccrtid_desc LIKE type_t.chr30,

   END RECORD

   END FOR
