从Java运行DELETE时出现SQL语法错误

Question

我收到错误ERROR：“（”或附近的语法错误

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));

问题是补充时缺少空格 。

想象以下情况：

“字” +“字2”

这将导致"wordword2"

所以应该

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