This is tricky because if the missing data is the unique identifier, it will likely need that information to bring it up, thus resulting in the same error.
Hopefully, your application will have some sort of interface that will allow you to bring up the particular record and add the missing data. Since there is nothing there, the MySQL engine gets confused and complains via a 1064 error. If the $id is never properly filled in the code, the query would look like this to the server: SELECT * from students WHERE studentID = Such a query would look like this: SELECT * from students WHERE studentID = $id For example, if a database is built requiring an ID number for every student, it is reasonable to assume a query will be built to pull a student record by that ID number. This causes issues when the data is required for a query to complete. Sometimes data can be missing from the database. CREATE TABLE `alter` (first_day DATE, last_day DATE) Missing Data The code block below shows how the code will need to look in order to run properly.
To fix the issue, you will want to surround the word with backticks, this is usually the button just to the left of the “1” button on the keyboard. Just because the word alter is reserved does not mean it cannot be used, it just has special requirements to use it as the MySQL engine is trying to call the functionality for the alter command. CREATE TABLE alter (first_day DATE, last_day DATE) For example, below is a short SQL query that uses a reserved word as a table name. If you attempt to use one of these reserved words, you will receive the 1064 error. These are words that are used for specific purposes or to perform specific functions within the MySQL engine. Using Reserved WordsĮvery version of MySQL has its own list of reserved words. Follow along so you can get your SQL queries updated and running successfully. Since the 1064 error can have multiple causes, we will go over the most common things that will result in this error and show you how to fix them. This may seem cryptic since it is a general error pointing to a syntax issue in the SQL Query statement. EverSQL SQL Query Syntax Check & Validator.
Note: Since syntax errors can be hard to locate in long queries, the following online tools can often save time by checking your code and locating issues: So follow along and learn more about what the 1064 error is, some likely causes, and general troubleshooting steps. The 1064 error displays any time you have an issue with your SQL syntax, and is often due to using reserved words, missing data in the database, or mistyped/obsolete commands.
