我在使用进步4GL
我有一个数据电子表格 包含数栏数据1... 50
我创造了一个保有所有价值的 临时工作表。
现在我想绕过临时表格的柱子 进行各种计算
所以我需要这样的东西:
for each record loop thru cols_in_temp_table .
if col_value = "XYZ" then
do calcs and stuff
end.
那么,我该如何参照 临时性的花椰子?

Ok, 未解析原始查询, 但找到了一个变通办法 。 将数据拆分并放入不同的表格中, 长长的括号, 但它会操作 。
依你的版本而定,这是做到这一点的一种方式:
DEFINE VARIABLE h-cols AS HANDLE NO-UNDO.
h-cols = tt-cols:BUFFER-HANDLE.
FOR EACH tt-cols
NO-LOCK:
IF h-cols::col-name = "some value" THEN
RUN do-something.
END.
无法做“ : : ” 操作员的版本, 请这样做 :
FOR EACH tt-cols
NO-LOCK:
IF h-cols::buffer-field("col-name"):buffer-value = "some value" THEN
RUN do-something.
END.
