Question

我需要一个检查DebugData的正则表达式，如果它有除字母[a-zA-Z]以外的任何数字或特殊字符，请用空格替换这些特殊字符。这些表存在于Google Big Query中，我正在使用IPython笔记本查询它。

示例：当DebugData为Movist2时，则ActualCarrier应为Movist，当DebugData为LAO GS2时，ActualCarrier应为LAOGS2，当DebugData为CLARO＆＃34; 3时，则ActualCarrier为CLARO。

SELECT 
Id, e.Carrier as AssignedCarrier, 
CASE
 WHEN lower(DebugData) LIKE 'jasp%' THEN 'Jasper' 
 WHEN lower(DebugData) LIKE 'telu%' THEN 'Telus'
 WHEN REGEXP_MATCH(DebugData,'\\w+\\d+') THEN DebugData
 WHEN REGEXP_MATCH(lower(DebugData),'\\d+') THEN c.Network
END
AS ActualCarrier
FROM debug_table

这是我补充的声明：

ELSE REGEXP_REPLACE(lower(DebugData),'\\[^a-zA-Z]',' ')

我仍然得到这个输出：

HardwareId  DebugData   ActualCarrier   count
550466188   CLARO"3      None            5

Answer 1

看起来像：

var hpDim = function() {
     var qNondArray = qNond();
  var mySpline = new MonotonicCubicSpline(
    qNondArray, [16.60, 16.60, 16.52, 16.34, 16.17, 15.91, 15.47, 15.12, 14.77, 14.33, 13.90, 13.46]);
  var total = mySpline.interpolate(qdim());
  $('#hpDim').val(+total.toFixed(2));
  return total;
};
hpDim();

尝试

SELECT
  DebugData, 
  REGEXP_REPLACE(DebugData, r'[^a-zA-Z]', ' ') as ActualCarrier 
FROM
  (SELECT'Movist2' as DebugData),
  (SELECT'LAO GS2' as DebugData),
  (SELECT'CLARO"3' as DebugData)

已添加以解决其他评论/问题

SELECT
  DebugData, 
  CASE
    WHEN REGEXP_MATCH(LOWER(DebugData),r'^\d+$') THEN Network 
    ELSE REGEXP_REPLACE(LOWER(DebugData),r'[^a-zA-Z]', ' ') 
  END AS ActualCarrier
FROM
  (SELECT'123' AS DebugData, 'aaa' AS Network),
  (SELECT'Movist2' AS DebugData, 'bbb' AS Network),
  (SELECT'456' AS DebugData, 'ccc' AS Network),
  (SELECT'LAO GS2' AS DebugData, 'ddd' AS Network),
  (SELECT'CLARO"3' AS DebugData, 'eee' AS Network),
  (SELECT'Test' AS DebugData, 'fff' AS Network)

正则表达式检查删除字母以外的字符
