Question

我在MYSQL中执行此查询时遇到错误。你能帮我解决一下这个问题。这是查询。

IF ('"+ @[User::CrMgName] +"' IS NULL)
THEN
Update companies
  Set crm_id = '"+ @[User::crm_guid] +"'
Where TRIM(LOWER(company_directory_name)) = '"+ @[User::EquityStoryId] +"'

ELSE
Update companies
  Set cr_manager = '"+ @[User::CrMgName] +"',
crm_id = '"+ @[User::crm_guid] +"'
Where TRIM(LOWER(company_directory_name)) = '"+ @[User::EquityStoryId] +"'  
END IF

Answer 1

评论之后，如果在脚本中使用IF语句表示该问题。

所以，解决方案是两个：

（正如Fari所说）：使用存储过程
将IF语句替换为CASE语句

对于解决方案2.试试这个：

UPDATE companies
SET crm_id = 
CASE 
   WHEN @[User::CrMgName] IS NULL THEN '"+ @[User::crm_guid] +"'
   ELSE'"+ @[User::crm_guid] +"'
END,
cr_manager = 
CASE
  WHEN @[User::CrMgName] IS NULL THEN cr_manager
  ELSE '"+ @[User::CrMgName] +"'
END
WHERE TRIM(LOWER(company_directory_name)) = '"+ @[User::EquityStoryId] +"'

使用带有变量值
