  • TIPTOP之分割split函数方法、getIndexOf、subString、replace、临时表创建;

    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:

      LET l_token = base.StringTokenizer.create(ps_token,",")

       WHILE l_token.hasMoreTokens() 
          LET ls_token = l_token.nextToken()
              CALL cl_schedule_chk_mapping(ls_token,pd_field) 
        END WHILE

    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,
