How to Fix 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax' in PDO?

PDO Syntax Error: "You Have an Error in Your SQL Syntax"

When running a SQL query with PDO, you may encounter the error "SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax." This error often occurs when a reserved keyword is used as a column name without proper quoting.

The example provided uses the column name "from" in the INSERT statement. "from" is a reserved keyword in SQL and must be quoted using backticks (`).

$sql = "INSERT INTO messages (`from`, `to`, `name`, `subject`, `message`) VALUES (:from, :to, :name, :subject, :message)";

Additionally, "to" is also a reserved keyword and should be quoted as well.

$sql = "INSERT INTO messages (`from`, `to`, `name`, `subject`, `message`) VALUES (:from, :to, :name, :subject, :message)";

Another option is to rename the column to avoid using a reserved keyword. For example, instead of "from," you could use "sender" or "from_email."

Renaming the column or quoting the reserved keyword should resolve the syntax error and allow the query to execute successfully.
