[Bug Report]
Introduction
In this bug report, we will be discussing an issue that arises when running a SQL query in the Adempiere application. The query in question is used to fill a table with invoice history data. However, due to a missing white space before the ORDER BY clause, the query fails with a SQL error. In this article, we will delve into the details of the issue, provide steps to reproduce it, and discuss the expected behavior.
The SQL Error
The SQL error in question is a PostgreSQL error that occurs when the query attempts to execute the ORDER BY clause. The error message is as follows:
org.postgresql.util.PSQLException: ERROR: trailing junk after numeric literal at or near "1046349O" Position: 423; State=42601; ErrorCode=0
This error message indicates that there is some trailing junk after a numeric literal in the query. In this case, the numeric literal is the product ID 1046349. However, the error message also mentions that there is some trailing junk, which is actually the character O that is appended to the product ID.
Steps to Reproduce
To reproduce this issue, you will need to have the Adempiere application installed on your system. You can download the latest version from the official website. Once installed, follow these steps:
- Open the Adempiere application and navigate to the Invoice History module.
- Click on the Fill Table button to execute the SQL query.
- Observe the error message that is displayed in the console.

Additional Context
The issue arises due to a lack of standardization in the placement of white space in the SQL query. Specifically, the white space before the ORDER BY clause is missing, which causes the query to fail. To resolve this issue, it is essential to agree on a standard for placing white space in SQL queries.
Conclusion
In conclusion, the SQL error due to missing white space before the ORDER BY clause is a critical issue that needs to be addressed. By following the steps outlined in this article, you can reproduce the issue and understand the root cause of the problem. The expected behavior is that the SQL query should execute successfully without any errors. To resolve this issue, it is essential to agree on a standard for placing white space in SQL queries.
Recommendations
Based on the analysis of this issue, the following recommendations are made:
- Standardize white space placement: Agree on a standard for placing white space in SQL queries to avoid similar issues in the future.
- Review SQL queries: Review all SQL queries in the Adempiere application to ensure that they follow the standardized white space placement.
- Test SQL queries: Test all SQL queries in the Adempiere application to ensure that they execute successfully without any errors.
Introduction
In our previous article, we discussed a critical issue that arises when running a SQL query in the Adempiere application. The query in question is used to fill a table with invoice history data, but due to a missing white space before the ORDER BY clause, the query fails with a SQL error. In this Q&A article, we will answer some frequently asked questions related to this issue.
Q: What is the root cause of the SQL error?
A: The root cause of the SQL error is a missing white space before the ORDER BY clause in the SQL query. This causes the query to fail with a PostgreSQL error.
Q: Why is the white space important in SQL queries?
A: White space is important in SQL queries because it helps to separate different parts of the query, such as the SELECT clause, the FROM clause, and the ORDER BY clause. Without proper white space, the query can become ambiguous and difficult to read.
Q: How can I reproduce this issue?
A: To reproduce this issue, you will need to have the Adempiere application installed on your system. You can download the latest version from the official website. Once installed, follow these steps:
- Open the Adempiere application and navigate to the Invoice History module.
- Click on the Fill Table button to execute the SQL query.
- Observe the error message that is displayed in the console.
Q: What is the expected behavior of the SQL query?
A: The expected behavior of the SQL query is that it should execute successfully without any errors. The query should return the invoice history data in the correct order, as specified by the ORDER BY clause.
Q: How can I resolve this issue?
A: To resolve this issue, you can follow these steps:
- Review the SQL query and add a white space before the ORDER BY clause.
- Test the SQL query to ensure that it executes successfully without any errors.
Q: What are the consequences of not resolving this issue?
A: If this issue is not resolved, it can lead to a range of consequences, including:
- Data corruption: The SQL query may return incorrect or incomplete data, which can lead to data corruption.
- Application crashes: The application may crash or become unresponsive due to the SQL error.
- Performance issues: The application may experience performance issues due to the repeated execution of the SQL query.
Q: How can I prevent similar issues in the future?
A: To prevent similar issues in the future, you can follow these best practices:
- Standardize white space placement: Agree on a standard for placing white space in SQL queries to avoid similar issues in the future.
- Review SQL queries: Review all SQL queries in the Adempiere application to ensure that they follow the standardized white space placement.
- Test SQL queries: Test all SQL queries in the Adempiere application to ensure that they execute successfully without any errors.
