Question

我正在尝试执行以下查询，但是它不满足我在where子句中提到的条件。它必须首先选择36、48、60中的术语，如果该术语为48，则该值不应介于-107至-305之间；如果该术语为60，则该值不应介于0至87之间且不包含-1304，-1204，如果term是36，则值不应大于-300。但是，当我运行查询时，它给出了排除中提到的所有值。请帮助

您可以在下面使用花括号尝试设置OR运算符的优先级

add_action( 'woocommerce_process_product_meta', 'cfwc_save_sample_product_id' );
function cfwc_save_sample_product_id( $post_id ) {
    $product = wc_get_product( $post_id );
    $title = isset( $_POST['custom_text_field_sample_product_id'] ) ? 
    $_POST['custom_text_field_sample_product_id'] : '';
    $product->update_meta_data( 'custom_text_field_sample_product_id', sanitize_text_field( $title ) );
    $product->save();
}

add_filter( 'woocommerce_add_to_cart_validation',  'only_four_items_allowed_add_to_cart', 10, 3 );
function only_four_items_allowed_add_to_cart( $passed, $product_id, $quantity ) 
    {
    $cart_count = WC()->cart->get_cart_contents_count();
    $total_count = $cart_count + $quantity;
    if ( has_term( 'Sample Product','product_cat',$product_id ) && ( $cart_count >= 4 || $total_count > 2 ) ) {
        $passed = false; // Set to false
        $notice = __( "You Can add only 2 sample product , Can't Add More", "woocommerce" ); // Notice to display
    }

    if( ! $passed )
        wc_add_notice( $notice, 'error' );

    return $passed;
}

上面的查询不正确，您应该使用WHEN-THEN条件才能获得所需的结果。

理想情况下，您应该在SQL中使用大小写。如下所示：

SELECT
      CASE
        WHEN <Condition> AND <Condition>
            THEN
               --do your select query--
        WHEN <Condition> AND <Condition>
            THEN
                --do your select query-
        ELSE
            -- default task --
     END
  FROM <table name>
