将SQL转储导入Eclipse

Question

I have imported a dumped sql file from MySQl Workbench, but when I try to run in Eclipse I keep getting this error message.

SQLException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'SET @OLD_CHARACTER_SET_RESULTS=@@CHARACTER_SET_RESULTS /; / !40101 SET @OLD_COL' at line 8

But when I copy the same information into MySQL it creates the schema and everything works fine. What am I doing wrong?

Here is my java code: http://pastebin.com/B1RVMYUd

And if you need it here is the dumpfile: http://pastebin.com/RWpG0BEX

Answer 1

您好，最好在mysql语句的查询中上传转储

Answer 2

You execute the whole contents of the dump as a single SQL statement. Try splitting the file contents (your sql String) using ; as the delimiter, and execute each statement separately.

(As an aside, it's good practice to put the calls to statement.close / conn.close in a finally clause, to make sure that the resources are always released.)

Answer 3

I'm a beginner, so my comments may not be the most clear or accurate, nor my code the most clear, concise, correct, etc. With that out of the way, here are a few things:

1) You can't use executeQuery(sql) method to create. So use one of the other options. In my experiments, I used:

sqlDumpArray = sqlDump.split(";");

for (int i = 0; i < sqlDumpArray.length; i++) {
    System.out.println("\nsqlDumpArray[" + i + "] is: " + sqlDumpArray[i]); // To see what's in the array.
    }

    for (int j = 1; j < sqlDumpArray.length -1; j++) { // Ugly hack because sqlDumpArray[0] and sqlDumpArray.length-1 are problematic in this alpha version of code.
       try {
          Statement statement = conn.createStatement();
          statement.addBatch(sqlDumpArray[j]);               
          statement.executeBatch(); // Maybe could move this out of the for-loop.
       }

Regarding the SQL file:

1) Strip out the comments. 2) Put a semicolon as the first character of the file (ie, row 1, column 1).

I did that and it works. Let me know if you want my complete code and I'll post it.
