Question

在Spotfire中，我有两个带有共享列“ id”的表“ A”和“ B”。令x为A中标记行的“ id”值的集合。我想向B添加新列“ flag”，使得：

flag = 1
flag = 0否则

有人可以帮我编写一个脚本（我猜是IronPython）来实现吗？这是一个示例（a，b，c和x，y，z列无关紧要）：

   A: id a b c
      1*  
      2 
      2*
      3
      3

（*为标记行）

   B: id x y z
       1
       1
       2
       2
       2
       3
       3

应导致：

   B: id x y z flag
       1       1 
       1       1 
       2       1
       2       1
       2       1
       3       0
       3       0

Answer 1

由于niko的评论和以下示例脚本，我找到了解决方案：

这是主意：

收集A中标记的“ id”值的集合x
使用第二个标记，在B中标记'id'值为x的行
将标记“ 0”分配给B中的所有行，然后将标记“ 1”仅分配给B中的已标记行

我手动创建了带有“ 0”和“ 1”标签的“标志”列。我不确定这是否也可以自动化。

这是完整的脚本：

sourceTableName           = 'A'
sourceMarkingName         = 'Marking'
sourceTableIDColumnName   = 'id'

targetTableName           = 'B'
targetMarkingName         = 'Marking (2)'
targetTableIDColumnName   = 'id'
targetTableFlagColumnName = "flag"


from System.Collections.Generic import List
from Spotfire.Dxp.Data import *


dataManager   = Application.Document.Data
sourceTable   = Document.Data.Tables[sourceTableName]
sourceMarking = dataManager.Markings[sourceMarkingName]
targetTable   = Document.Data.Tables[targetTableName]
targetMarking = dataManager.Markings[targetMarkingName]


#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#
# step 1: get set of id values marked in source table
#
#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

# Create a cursor for the table column to get the values from
sourceCursor = DataValueCursor.CreateFormatted(sourceTable.Columns[sourceTableIDColumnName])

# Create a List object to store the values for the rows marked in the source table
markedData = List[str]();

# Iterate through the source data table rows to retrieve the marked values
for row in sourceTable.GetRows(sourceMarking.GetSelection(sourceTable).AsIndexSet(), sourceCursor):
    value = sourceCursor.CurrentValue
    if value <> str.Empty:
        markedData.Add(value)

# Get the unique values
idValues = sorted(List[str](set(markedData)))


#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#
# step 2: use the id values to mark rows in target table
#
#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

# Set marking of all rows in target table to False
rowsToSelect = IndexSet(targetTable.RowCount, False)

targetCursor = DataValueCursor.CreateFormatted(targetTable.Columns[targetTableIDColumnName])

# Iterate through the target table rows to set the marked rows
rowIndex = 0
for row in targetTable.GetRows(targetCursor):
    value = targetCursor.CurrentValue
    rowsToSelect[rowIndex] = value in idValues
    rowIndex += 1

# Set marking on targetTable
targetMarking.SetSelection(RowSelection(rowsToSelect), targetTable)

#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
#
# step 3: assign tag '1' to the marked rows and '0' to all other rows in the target table
#
#:::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::

# Get handle to the required column and typecast it to a tagcolumn
myTagColumn = targetTable.Columns.Item[targetTableFlagColumnName].As[TagsColumn]()

# get index to all rows
allRows = IndexSet(targetTable.RowCount, True)

# assign tags
myTagColumn.Tag('0', RowSelection(allRows))                     # assign '0' to all rows
myTagColumn.Tag('1', targetMarking.GetSelection(targetTable))   # assign '1' to marked rows
