大家好,
我有几个专栏:
1-“开始日期”列
2-“结束日期”列
通常,属于组 (2) 的每一列也应属于组 (1),反之亦然。 所以我们应该在两组中有相同数量的列。
但是,属于第 1 组的列不属于第 2 组,反之亦然。
例子: “开始日期 9899”,但“结束日期 9899”列不存在。
目标是让这两组相交,以便两组中有相同的列。
我受到以下代码的启发:Names Default To Here(1);
dt = Current Data Table();
// build
aa_duree = Associative Array();
aa_nonduree = Associative Array();
For Each({col_name}, dt << Get Column Names("String"),
If(Word(1, col_name) == "date début",
aa_duree[Word(-1, col_name)] = col_name;
, !IsMissing(Regex(col_name, "")),
aa_nonduree[col_name] = 1;
,
continue()
);
);
show(aa_duree);
show(aa_nonduree);
aa_duree_copy = aa_duree;
aa_duree_copy << Intersect(aa_nonduree);
cols_to_keep = Insert(aa_duree_copy << get keys, aa_duree_copy << get values);
aa_duree_copy2 = aa_duree;
aa_nonduree_copy = aa_nonduree;
aa_duree_copy2 << remove(aa_nonduree);
aa_nonduree_copy << remove(aa_duree);
cols_to_remove = Insert(aa_nonduree_copy << get keys, aa_duree_copy2 << get values);
show(cols_to_keep, cols_to_remove); 您提供的示例脚本将不起作用,因为 Word(1, col_name) 只会返回字符串的第一个作品,而您正在将它与两个单词进行比较。 因此 if 语句将始终转到 else 语句。 可能还有其他问题,但这至少是一个问题。 您可以尝试将 Words 例如更改为 Starts With() https://www.jmp.com/support/help/en/17.0/#page/jmp/character-functions-2.shtml?os=win&source=application#ww2489516 . 还要确保比较字符串时大小写正确
这是我解决这个问题的老派方法
Names Default To Here( 1 );
dt = Current Data Table();
keep = {};
delete = {};
colNameList = dt << get column names( string );
For Each( {col, i}, colNameList, colNameList[i] = Uppercase( col ) );
While( N Items( colNameList ) > 0,
If(
Contains( colNameList[1], Uppercase( "Date début" ) ),
found = Contains( colNameList, Substitute( colNameList[1], Uppercase( "début" ), "FIN" ) );
If( found > 0,
Insert Into( keep, colNameList[1] );
Insert Into( keep, colNameList[found] );
Remove From( colNameList, found, 1 );
Remove From( colNameList, 1, 1 );
,
Insert Into( delete, colNameList[1] );
Remove From( colNameList, 1, 1 )
);,
Contains( colNameList[1], Uppercase( "Date fin" ) ),
found = Contains( colNameList, Substitute( colNameList[1], "FIN", Uppercase( "début" ) ) );
If( found > 0,
Insert Into( keep, colNameList[1] );
Insert Into( keep, colNameList[found] );
Remove From( colNameList, found, 1 );
Remove From( colNameList, 1, 1 );
,
Insert Into( delete, colNameList[1] );
Remove From( colNameList, 1, 1 )
);,
Remove From( colNameList, 1, 1 )
)
);
show( keep, delete );
