[英]Error in SQL - This is not permitted when the subquery follows =, !=, <, <= , >, >= or when the subquery is used as an expression
我正在嘗試根據兩個條件更新字段
UPDATE TABLE1 SET FIELD1 = (SELECT SUBSTRING(LEFT(FIELD2,3),2,2) FROM TABLE1) WHERE FIELD2 LIKE '0%' AND FIELD3 IN ('OK','YES')
UPDATE TABLE1 SET FIELD1 = (SELECT SUBSTRING(LEFT(FIELD2,3),1,2) FROM TABLE1) WHERE FIELD2 NOT LIKE '0%' AND FIELD3 IN ('OK','YES')
Field1的數字以0和1開頭。如果以0開頭，則更新第一個查詢。 如果為1，則第二個查詢
您不需要子查詢。 所有你需要的是：
UPDATE TABLE1
SET FIELD1 = SUBSTRING(LEFT(FIELD2,3),2,2)
WHERE FIELD2 LIKE '0%'
AND FIELD3 IN ('OK','YES')
