如何提高此 Google 表格自定义功能的性能？

Answer 1

使用这个漂亮的项目AlaSQLGS~

我们可以使用AlaSQL 来简化许多（imo）在数据库中比javascript/appscript 更好的数据操作功能。

这是一个您可以使用您的数据进行修改的示例：

const alasql = AlaSQLGS.load()

function Update_Results() {
  const groupUUID = '91c7db0a-c52a-407d-869a-af8ba8bf8ba7';
  const role = 'Pilot';
  const inputSheetName = 'INPUT';
  const outputSheetName = 'RESULTS_Pilot';

  const ss = SpreadsheetApp.getActiveSpreadsheet();
  const inputSheet = ss.getSheetByName(inputSheetName);
  const outputSheet = ss.getSheetByName(outputSheetName)
  
  let data = inputSheet.getDataRange().getValues();
  data.shift() // Remove column names~
  
  // Create a Table and insert values into it.
  // I use \` so often, because you have Spaces and illegal sql column names.
  // Note that these are backticks, not single quotes.
  alasql(`
    CREATE TABLE data (
      \`Instance Id\` STRING,
      \`Group Id\` STRING,
      \`Field name\` STRING,
      \`Field Id\` STRING,
      \`Value\` INT,
      \`File Id\` STRING,
      \`Role\` STRING
    );
    SELECT [0] AS \`Instance Id\`
         , [2] AS \`Group Id\`
         , [3] AS \`Field name\`
         , [4] AS \`Field Id\`
         , [6] AS \`Value\`
         , [7] AS \`File Id\`
         , [8] AS \`Role\`
    INTO data
    FROM ?;
  `, [data])

  // Query the Table
  // MATRIX gives us an Array of Arrays instead of an Array of Objects.
  let output = alasql(`
    SELECT MATRIX
           \`Instance Id\`
         , \`Field name\` 
         , \`File Id\`
         , [Value]
      FROM data
     PIVOT (MAX([Value]) FOR \`Field name\`)
     WHERE \`Group Id\` = ?
       AND \`Role\` = ?
  `, [groupUUID, role]);
  
  // Add Column Names
  output.unshift(['Instance Id', 'File Id', ...output[0].slice(2).map((x,i) => `Field ${i+1}`)])
  
  // Insert the result into the sheet
  outputSheet.clearContents()
  outputSheet.getRange(1, 1, output.length, output[0].length).setValues(output);

  Logger.log(output)
}

记录器输出：

[[Instance Id, File Id, Field 1, Field 2, Field 3],
 [Instance1A, Pilot_File, 100.0, 200.0, 300.0],
 [Instance1B, Pilot_File, 110.0, 220.0, 330.0]]

GSheet 输出：

Instance Id	File Id	Field 1	Field 2	Field 3
Instance1A	Pilot_File	100	200	300
Instance1B	Pilot_File	110	220	330

Answer 2

当一个普通的电子表格公式似乎就足够了时，为什么你需要一个自定义函数呢？目前还不清楚。尝试使用 query() 和 pivot 子句，如下所示：

=query(INPUT!A1:K, "select A, max(G), H where I = 'Pilot' group by A, H pivot D", 1)

=query(INPUT!A1:K, "select A, max(G), H where I = 'Co-Pilot' group by A, H pivot D", 1)

这些公式与您当前的自定义函数结果完全匹配，它们应该运行得更快。
