具有多个LIKE条件的SQL ESCAPE

Question

我想为多个LIKE条件指定相同的转义字符。哪个是对的？

SELECT * FROM [table] WHERE [column1] LIKE 'value1!%'            AND [column2] LIKE 'value2!%' ESCAPE '!'
SELECT * FROM [table] WHERE [column1] LIKE 'value1!%' ESCAPE '!' AND [column2] LIKE 'value2!%' ESCAPE '!'
SELECT * FROM [table] WHERE [column1] LIKE 'value1!%' ESCAPE '!' AND [column2] LIKE 'value2!%'

还是别的什么呢？

Answer 1

你的第二项是正确的：

SELECT * FROM [table] WHERE [column1] LIKE 'value1!%' ESCAPE '!' AND [column2] LIKE 'value2!%' ESCAPE '!'
