SQLSTATE[42000]: Syntax Error Or Access Violation: 1064 You Have An Error In Your SQL Syntax — PHP — PDO

The SQLSTATE[42000]: Syntax error or access violation: 1064 error in PDO (PHP Data Objects) usually occurs when there is a syntax error in your SQL query. Here are a few common causes and solutions for this error:

  1. Incorrect SQL Syntax: Double-check your SQL query for any syntax errors, such as missing or misplaced commas, parentheses, or quotes. Make sure all table and column names are correct and properly enclosed in backticks (`) or quotes (‘).

  2. Reserved Keywords: If you are using any reserved keywords as table or column names, you need to enclose them in backticks () to avoid conflicts. For example, orderis a reserved keyword in MySQL, so you would need to write it asorder`.

  3. Invalid Data Type or Format: Ensure that you are passing the correct data type and format in your SQL query. For example, if you are inserting a string value, make sure it is enclosed in quotes (”).

  4. Missing or Mismatched Bind Parameters: When using prepared statements in PDO, make sure you have included all the necessary bind parameters in your query and that they match the number and order of your placeholders. If you miss a bind parameter or include an extra one, it can cause a syntax error.

  5. Using Quotes for Table or Column Names: In standard SQL, table and column names should be enclosed in backticks (`). However, some databases may use quotes (") instead. Ensure that you are using the correct quotation marks for your database.

  6. Multiple SQL Statements: PDO does not allow executing multiple SQL statements in a single query. If you are trying to execute multiple statements, you need to separate them into separate PDO statement executions.

By analyzing your specific SQL query and error message, you will be able to identify the exact cause of the error and apply the appropriate solution.
