Usually, SQL0104N indicates a syntax problem within your query statement. Hence double-checking your script’s syntax using online validation tools like DB2 Validator as part of your pre-release checklist could help avoid potential issues before they arise in production environment.
Step 2: Identify Interpretation Issues
Another possibility for SQL104NFailure/An Unexpected Token Was Found Can Be The Use Of Non-Literal Strings In Queries For Special Characters Or Keywords That Might Have Different Underlying Meanings Than What You Intend Them To Convey (““, ~ , et al.). These translate differently depending on OS compatibility; thus verifying available language sets against our server could prevent interpretational discrepancies resulting in similar errors/errors thrown back up during execution.
Step 3: Look Out For Case Sensitivity Issues
DBs created through different installations sometimes have case sensitivity issues where strings with uppercase characters are not recognized by the DB if they are lower case when being called during execution. Be sure to check for casesensitivity differences with a database or table, and correct yours as needed.
Step 4: Use Correct Delimiters
It’s critical always to use appropriate delimiters while calling INNER JOIN or WHERE CLAUSE CHAINING in your query script. Special characters like parentheses, semicolons, quotation marks et al., come into play here so make yourself aware of which db-specific character fits best & tweak accordingly.
Step 5: Review Your SYNTAX Repeatedly
Once again review step-by-step every syntax line carefully before executing commit commands since typical queries include several chained clauses that lead to trial-and-error style debugging runs until everything is correctly implemented – taking this approach will help minimize any further errors that might cause setbacks after initial testing cycles have been completed successfully

The Top 5 Things You Need to Know About the SQL0104N Error: An Unexpected Token Was Found Following
If you’re an experienced database professional, you’ve likely come across a multitude of errors over the course of your career. One such error is SQL0104N, which has the following message: “An unexpected token was found following…”. This error can be frustrating and confusing to even the most seasoned DBAs. However, with some knowledge and know-how, solving this issue need not be difficult. Here are five things that you should know about this particular error:
1) The Source of Error
Attempting to execute SQL statements against an IBM DB2 for iSeries database may encounter SQL0104N error associated with one or more tokens in it that cannot be correctly processed by system’s parser engine.
The term ‘token’ here stands for identifiers such as table names or field names used within your query statement. If there is a syntax problem within these identifiers then it would trigger an SQL104N exception while running on iSeries machines.
2) Understand Common Tokens
One common source for this type of error occurs when there is incorrect use of single quotes (‘) in string literals causing errors where another identifier starts too soon e.g., SELECT column_name FROM my_table WHERE {column_name} = ”some_value’.
Another reason behind ‘Unexpected Token’ errors may happen due to reserved words being use incorrectly without enclosing them into square brackets [ ]. An example can be seen in where we want ‘Table’ specified as column name but its keyword conflict becomes problematic- SELECT Table from Employees . Square bracket solution ensures successful processing – SELECT [Table] FROM Employees .
3) Check Your Syntax Carefully
Prevention is always better than cure – read through all queries before executing any code! When debugging an unexpected token error, double-checking often helps identify tiny mistakes missed initially like random extra spaces or typos.
It’s important to note here that user-defined structures like Stored Procedures and Triggers inherit their dependencies from parent tables/structures. So, ensure that any changes made to the parent structures are implemented similarly in all dependent objects.
4) Different Database Engines have Separate Syntaxes
Not all database engines support every syntax of SQL language nor does IBM DB2 AS/400 for iSeries. Knowing your specific system’s limitations can pay dividends by avoiding making queries without a chance of them working properly- thus reducing unnecessary errors and processing time .
5) Error Codes Can Help You Analyzing the Issue
Error codes provide vital clues into what went wrong by cross-referencing with documentation provided by vendor or online forums available on solutions like Stack Overflow. An example error message illustrated below:
SQL0104N An unexpected token “SELECT” was found following “UPDATE my_table SET”.
Expected tokens may include: ” “. SQLSTATE=42601
The highlighted section above helps understand likely cause – namely an invalid sequence during ‘Update’ command execution indicating possible semantic issue .
In conclusion, understanding these basic tips about resolving SQL105N parsing problem is important especially when dealing with large data sets or critical mission-critical transactions where performance & reliability counts. It will save you lots of frustration, debugging hours and possibly even prevent accidental data loss!

Common Mistakes that Trigger the SQL0104N Error – Tips on How to Prevent Them
As an SQL developer or administrator, you may have encountered the notorious “SQL0104N” error more than once. This error is caused by a variety of issues that can be hard to identify and fix, leading to lost time, frustration, and even potential data loss. Fortunately, with careful attention to best practices and common mistakes, you can prevent this error from happening in the first place.
Here are some of the most common mistakes that trigger the SQL0104N error:
1. Incorrect object names: One of the primary causes of this error is using incorrect object names such as tables or columns. It’s essential always to double-check your syntax before running queries.
2. Invalid characters: Special characters such as spaces or special symbols should not be included in table/column names or query commands; otherwise, they will generate errors during runtime. Keeping a consistent naming convention for your database objects helps avoid these types of errors.
3. Case sensitivity: Unlike many programming languages, which are often case-insensitive when it comes to naming conventions (e.g., Python), SQL is strictly case-sensitive when it comes to table/object names – so “mytable” and “MyTable” would be treated as two different entities, potentially causing confusion if called together in one statement.
4. Permissions issues: Permission problems could also create issues while working with databases involving both security configurations like access rights or grants assigned on certain user roles/permissions/user IDs & views.
5.Incompatible Data Types – When dealing with multiple tables/join statements returning incompatible data types (integer vs decimal etc.) without any explicit conversion leads invariably results in SQL0104N issue
There’s no definitive solution for preventing all these errors since every situation differs depending upon application requirements but here’s some tips on how IT professionals can minimize their occurrence:
– When writing SQLs make sure there aren’t any typos within that command!
– Be consistent regarding object/naming structure
– You should use higher versions of databases ensuring the least possible TAT for SQL transactions
– Always keep an eye on whether you have assigned appropriate access rights or not, always follow a certain predefined structure convention
In closing, preventing innocuous mistakes can save significant time and effort in resolving complex data issues. Therefore making these best practices a habit will help IT professionals alike prevent errors that could lead to disrupted workflows and system outages.
