PreparedStatement don't insert Data into MySQL DB
I have the following Database:
CREATE TABLE b (
name VARCHAR(255) NOT NULL,
text MEDIUMTEXT NOT NULL,
PRIMARY KEY (NAME)
);
And I have the following code:
public void saveBlocks(Map<String, Block> blocks) throws SQLException{
String userInsertQuery = "Insert INTO b (name, text) VALUES (?, ?)";
preparedStatement = connect.prepareStatement(userInsertQuery);
int batchCounter = 0;
for(Block block : blocks.values()){
preparedStatement.setString(1,block.getId());
preparedStatement.setString(2,block.getText());
preparedStatement.addBatch();
batchCounter++;
if(batchCounter%200 == 0) {
preparedStatement.executeBatch();
}
}
preparedStatement.executeBatch();
}
But it doesn't write anything into the database.
I have nearly the same code for another table and there it works without a problem. The only difference is the amount of inserts I do (in the working case: over 1million, in the non working case: around 70)
I can't find a solution and I'm out of ideas.
What I tried:
- connect.commit() => since I have autocommit true no change. (or do I use it wrong?)
- I don't have a auto increment on my key so no problem there.
You have any ideas?

You must finally commit the transactions with:
connect.commit();
with connect.setAutoCommit(false);
String userInsertQuery = "Insert INTO b (name, text) VALUES (?, ?)";
preparedStatement = connect.prepareStatement(userInsertQuery);
connect.setAutoCommit(false);
int batchCounter = 0;
for(Block block : blocks.values()){
preparedStatement.setString(1,block.getId());
preparedStatement.setString(2,block.getText());
preparedStatement.addBatch();
batchCounter++;
}
int results = preparedStatement.executeBatch();
connect.commit();
