shouhengyi opened a new issue #7324: URL: https://github.com/apache/pinot/issues/7324
In [PreparedStatement.java](https://github.com/apache/pinot/blob/master/pinot-clients/pinot-java-client/src/main/java/org/apache/pinot/client/PreparedStatement.java), if `value` argument in the `setString` method contains dollar sign "$", it will cause `IndexOutOfBoundsException` when `fillStatementWithParameters` is invoked. For example, if `value` is `"$8.00"`, we will get exceptions like this. ``` java.lang.IndexOutOfBoundsException: No group 8 at java.util.regex.Matcher.start(Matcher.java:375) at java.util.regex.Matcher.appendReplacement(Matcher.java:880) at java.util.regex.Matcher.replaceFirst(Matcher.java:1004) at java.lang.String.replaceFirst(String.java:2178) at org.apache.pinot.client.PreparedStatement.fillStatementWithParameters(PreparedStatement.java:61) ... ``` This is due to that the dollar sign $ is not properly escaped. To fix this issue, our proposal is to escape dollar sign in the `value`: ``` public void setString(int parameterIndex, String value) { _parameters[parameterIndex] = "'" + value.replace("'", "''").replace("$", "//$") + "'"; } ``` -- This is an automated message from the Apache Git Service.
