如何处理更新查询的 where 子句中的多行 (BigQuery)

Question

我正在尝试使用具有多行 where 子句的更新查询。 它包含引号、空格和换行符。 反斜杠适用于反逗号，但不能处理子句中的空格和空行。 由于它是一个更新 where 子句，我将无法更改子句的结构，否则它将与现有值不匹配。

UPDATE dataset.datatable 
SET project = "something" 
WHERE identifier="The $1.90M adajdshsas ahsdsjahd adsad add adddadcxv ksdf sdfsd sdfsff.  

adjajasd by ahsdhasf kkjfdsg \"kasf the new uenf will\" ensure #maidsbd and surrounding communities will have greater access to #madaudafvys support and sajdahdj locally.

#hasdad #sadauyd 

asdahda, asdad\'s dshag, minadahdh"

我尝试使用like 代替，但是列中的相似值太多。

UPDATE dataset.datatable 
SET project = "something" 
WHERE identifier LIKE "%The $1.90M%" AND identifier LIKE "%\"kasf the new uenf will\"%"

有没有办法处理这种情况，或者我是否必须通过删除所有非字母数字字符来修改表中的列？

下面的示例演示了该方法

CREATE TEMP TABLE your_table as (
SELECT 1 id, "abc12345678" project, r"""The $1.90M adajdshsas ahsdsjahd adsad add adddadcxv ksdf sdfsd sdfsff.  

adjajasd by ahsdhasf kkjfdsg \"kasf the new uenf will\" ensure #maidsbd and surrounding communities will have greater access to #madaudafvys support and sajdahdj locally.

UPDATE  your_table
SET project = "something" 
WHERE  identifier = r"""The $1.90M adajdshsas ahsdsjahd adsad add adddadcxv ksdf sdfsd sdfsff.
