READ命令使用顺序查找数据表,这会降低处理速度。取而代之,使用binary search的附加命令,可以使用二分查找算法,可以帮助加快内表查找速度。 在使用binary search之前必须首先将内表排序,否则有可能找不到记录,因为二分查找反复将查找区间对半划分,如果要查找的值小于查找区间的中间位置的数据项值,则查找区间将缩小到前半...
automatically for sorted tables), if there are several hits (because of an incompletely specified search key or because there are duplicate entries in the table), thenthe first hitin terms of the sequence of the rows is always returned, that is, the row with the smallest index. ...
SAP Managed Tags: ABAP Testing and Analysis before using BINARy SEARCH the internal table must be SORTed on the fields which we are using in READ statement. Now binary search looks the middle record in the internal table. if the KEY is less than the middle record then it will take first...
SAP Managed Tags: ABAP Testing and Analysis Hi ram, I think the question you are asking is regarding the Binary search. In the second case as you are using binary search and the table is sorted . the read statement will be fast than the first one. beware you need to sort the table...
The READ statement uses a binary search to look for and find the line in the table where COL2 has the value 16. Reward points if helpful. Regards, Hemant Reply Former Member 2007 May 09 8:06 AM 0 Kudos 398 SAP Managed Tags: ABAP Development hi, linear search searches one...
SAP Managed Tags: ABAP Development Hi Ravi, You cant be certain which record will be picked.It will bring any record matching the criterion.Because in simple read statement,sequential search is performed.But logic for binary search is different.Binary search repeatedly divides the search interval...

SAP ABAP READ TABLE binary search明明有值但就是取不到 read之前一定要排序,按照read的KEY字段进行排序,否则就可能取不到。 READ 不加BINARY SEARCH的取数逻辑, 其实是取第一笔数据
SAP Managed Tags: ABAP Development Would the following binary search produce correct results? Internal table IT is sorted by field1 field2 field3 read table IT with key field2 = 'X' field3 = 'Y' I am not sure this is correct since the read statement makes no reference to field1.Re...
Hence its mandt that the search filed of the table should be in Ascending order. Regards, Gurpreet Reply Former Member 2009 Apr 08 7:11 AM 0 Kudos 233 SAP Managed Tags: ABAP Development If you are using the Binary search in Read statement you should sort the internal table bef...
