Description

Starting from the filled mesh nodes mesh-node1 and mesh-node2, multiple rows from mesh-node2 are changed:

  • Statement MODIFY for deleting multiple rows using the ON condition.
MODIFY mesh-node1\to_node2[ mesh-node1[ 1 ] ]
  FROM VALUE line2( col3 = 111 ) TRANSPORTING col3.
All rows of the node mesh-node2 identified starting with the first row of the node mesh-node1 using the initial association \to_node2 are changed in the third column.
  • Statement DELETE for deleting multiple rows using the ON condition with an additional WHERE condition.
MODIFY mesh-node1\to_node2[ mesh-node1[ 2 ] WHERE col3 > 23 ]
  FROM VALUE line2( col3 = 222 ) TRANSPORTING col3.
All rows of the node mesh-node2 identified starting with the second row of the node mesh-node1 using the initial association \to_node2 and which meet the additional WHERE condition are changed in the third column.
