从Java运行DELETE时出现SQL语法错误

Question

我收到错误错误：语法错误在“（”

处或附近

String deleteSQL = "DELETE FROM customer" +
"WHERE (fname = 'Fred' AND lname = 'Flintstone')" +
"OR (fname = 'Barney' AND lname = 'Rubble')";
System.out.println("Records deleted: "
+ stmt.executeUpdate(deleteSQL));

Answer 1

String deleteSQL = "DELETE FROM customer " +
"WHERE (fname = 'Fred' AND lname = 'Flintstone') " +
"OR (fname = 'Barney' AND lname = 'Rubble') ";
System.out.println("Records deleted: "
+ stmt.executeUpdate(deleteSQL));

问题是在结合时缺少空格。

想象一下：

  

“word”+“word2”

这会导致"wordword2"

所以它应该是

"word" + " " + "word2" 或 "word "+ "word2"
