使用 JDBC 在工具中工作但在 Java 中不工作的 SQL 语句

Question

I'm using the below SQL query to fetch some data from the database. The DBMS I'm using is H2, a native java implementation. Even though I can retrieve said data using a H2 tool, it gives me the following error when I use it as a PreparedStatement in JAVA:

"; expected ")"; SQL statement: ...

SELECT * FROM (
   SELECT temp.*, ROW_NUMBER() OVER (PARTITION BY horseid ORDER BY updated desc) as num
   FROM(
   select horseid, name, breed, min_speed, max_speed, updated from horsehistory
   UNION
   select id, name, breed, min_speed, max_speed, updated from horse
   ) as temp
   WHERE updated<? AND horseid in ?
)
WHERE num = 1;

I've tried using newlines, stringbuilder with line separator to no avail.

StringBuilder sb= new StringBuilder();
    appendString(sb, "SELECT * FROM (");
    appendString(sb, "SELECT temp.*, ROW_NUMBER() OVER (PARTITION BY horseid ORDER BY updated desc) AS num");
    appendString(sb, "FROM(");
    appendString(sb, "SELECT horseid, name, breed, min_speed, max_speed, updated FROM horsehistory");
    appendString(sb, "UNION");
    appendString(sb, "SELECT id, name, breed, min_speed, max_speed, updated FROM horse");
    appendString(sb, ") AS temp");
    appendString(sb, "WHERE updated < ? AND horseid IN ?");
    appendString(sb, ")");
    appendString(sb, "WHERE num = 1;");
    String sql=sb.toString();

The appendString function just appends a newline to the String. I use this in a preparedstatement

What am I doing wrong?

EDIT: This is the full error in question

Syntax error in SQL statement "SELECT * FROM ( SELECT TEMP.*, ROW_NUMBER() OVER (PARTITION[*] BY        HORSEID ORDER BY UPDATED DESC) AS NUM FROM ( SELECT HORSEID, NAME, BREED, MIN_SPEED, MAX_SPEED, UPDATED FROM HORSEHISTORY UNION SELECT ID, NAME, BREED, MIN_SPEED, MAX_SPEED, UPDATED FROM HORSE ) AS TEMP WHERE UPDATED < ? AND HORSEID IN (?) ) WHERE NUM = 1  "; expected ")";

There is a [*] after PARTITION. Does this mean that the error occurs there?

Answer 1

You have to wrap your array-parameter ? in parentheses:

... horseid IN (?) ...

Answer 2

Ah, you're using H2 , thanks for adding that flag. H2 doesn't seem to support PARTITION . See here
