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));
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：
“单词” +“ word2”
这将导致 "wordword2"
所以应该
"word" + " " + "word2" 或者 "word "+ "word2"
