Hi Experts , Is there any way in ESQL coding for sorting of data from XML file.Thanks in advance
input :
<LIST>
<EMP>
<EMP_ID>4</EMP_ID>
</EMP>
<EMP>
<EMP_ID>3</EMP_ID>
</EMP>
<EMP>
<EMP_ID>1</EMP_ID>
</EMP>
<EMP>
<EMP_ID>2</EMP_ID>
</EMP>
</LIST>
Expecting output :
<LIST>
<EMP>
<EMP_ID>1</EMP_ID>
</EMP>
<EMP>
<EMP_ID>2</EMP_ID>
</EMP>
<EMP>
<EMP_ID>3</EMP_ID>
</EMP>
<EMP>

Here is code for sorting in ESQL
DECLARE SIZE INTEGER CARDINALITY(InputRoot.XMLNSC.LIST.*[]);
DECLARE rOutRef REFERENCE TO OutputRoot.XMLNSC;
DECLARE I,J INTEGER 1;
DECLARE A ,TEMP_F,TEMP_S,TEMP_SWITCH INTEGER;
SET OutputRoot.XMLNSC.aj.ARRAY[]=InputRoot.XMLNSC.LIST.EMP[];
WHILE J<=SIZE-1 DO
WHILE SIZE >I DO
SET TEMP_F=OutputRoot.XMLNSC.aj.ARRAY[I].EMP_ID;
SET TEMP_S=OutputRoot.XMLNSC.aj.ARRAY[I+1].EMP_ID;
IF TEMP_F>TEMP_S THEN
SET TEMP_SWITCH=OutputRoot.XMLNSC.aj.ARRAY[I].EMP_ID;
SET OutputRoot.XMLNSC.aj.ARRAY[I].EMP_ID=OutputRoot.XMLNSC.aj.ARRAY[I+1].EMP_ID;
SET OutputRoot.XMLNSC.aj.ARRAY[I+1].EMP_ID=TEMP_SWITCH;
END IF;
--SET A = SELECT MIN(t.EMP_ID) from OutputRoot.XMLNSC.aj.ARRAY[] as t;
--SET OutputRoot.XMLNSC.aj.ARRAY[A]=NULL;
SET I =I+1;
END WHILE;
SET J=J+1;
SET I=1;
END WHILE;
RETURN TRUE; |

If you post code, please use code tags.
I would not recommend doing the sorting using ESQL; Java is likely to be a lot faster and you don't have to write the sorting algorithm yourself ( although you do need to do some work to understand how Java collection classes work ). |
