This usually stems from improperly structured join conditions.</p> <p>Consider this flawed query:</p> <pre class="brush:php;toolbar:false"><code class="language-sql">SELECT ... FROM tbl_employee INNER JOIN tbl_netpay ON tbl_employee.emp_id = tbl_netpay.emp_id INNER JOIN tbl_gross ON tbl_employee.emp_id = tbl_gross.emp_ID INNER JOIN tbl_tax ON tbl_employee.emp_id - tbl_tax.emp_ID;</code></pre> <p>The error arises from the missing operator (<code>=</code>, <code>></code>, <code><</code>, etc.) in the final <code>INNER JOIN</code> between <code>tbl_employee</code> and <code>tbl_tax</code>.</p> <p>The solution involves using parentheses to clarify the join order within the <code>FROM</code> clause:</p> <pre class="brush:php;toolbar:false"><code class="language-sql">SELECT ... FROM ((tbl_employee INNER JOIN tbl_netpay ON tbl_employee.emp_id = tbl_netpay.emp_id) INNER JOIN tbl_gross ON tbl_employee.emp_id = tbl_gross.emp_ID) INNER JOIN tbl_tax ON tbl_employee.emp_id = tbl_tax.emp_ID;</code></pre> <p>By grouping the joins with parentheses, the query parser correctly interprets the join sequence and applies the appropriate operators.</p> <p><strong>Best Practices:</strong></p> <p>Always use parentheses in <code>FROM</code> clauses with multiple joins to avoid ambiguity and potential syntax errors. The Access query designer provides a visual interface that automatically handles parentheses and operator placement, offering a less error-prone method for creating complex joins.</p>
