In this context, one of the types of data that MySQL offers and that is crucial to know is <code>VARBINARY<\/code>. This type of data allows you to store bytes of variable length, which translates into a flexible and very useful capacity to handle binary data that varies in size, such as images, multimedia files, or even encrypted data. Throughout this article, we will explore how to use the data type <code>VARBINARY<\/code> in MySQL, providing you with all the necessary technical knowledge to implement it efficiently in your projects.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_80 counter-hierarchy ez-toc-counter ez-toc-custom ez-toc-container-direction\">\n<div class=\"ez-toc-title-container\">\n<p class=\"ez-toc-title\" style=\"cursor:inherit\">Table of Contents<\/p>\n<span class=\"ez-toc-title-toggle\"><a href=\"#\" class=\"ez-toc-pull-right ez-toc-btn ez-toc-btn-xs ez-toc-btn-default ez-toc-toggle\" aria-label=\"Toggle Table of Content\"><span class=\"ez-toc-js-icon-con\"><span class=\"\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #ffffff;color:#ffffff\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewbox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #ffffff;color:#ffffff\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewbox=\"0 0 24 24\" version=\"1.2\" baseprofile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/span><\/a><\/span><\/div>\n<nav><ul class='ez-toc-list ez-toc-list-level-1' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#%C2%BFQue_es_VARBINARY\" >What is VARBINARY?<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Ejemplo_basico_de_creacion_de_una_columna_VARBINARY\" >Basic example of creating a VARBINARY column<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Ventajas_de_usar_VARBINARY\" >Advantages of using VARBINARY<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-4\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Como_insertar_y_manejar_datos_VARBINARY\" >How to insert and handle VARBINARY data<\/a><ul class='ez-toc-list-level-3' ><li class='ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-5\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Insertar_datos_binarios\" >Insert binary data<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-3'><a class=\"ez-toc-link ez-toc-heading-6\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Recuperar_datos_binarios\" >Recover binary data<\/a><\/li><\/ul><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-7\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Buenas_practicas_al_usar_VARBINARY\" >Good practices when using VARBINARY<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-8\" href=\"https:\/\/nelkodev.com\/en\/blog\/efficient-data-handling-with-varbinary-in-mysql\/#Conclusion\" >Conclusion<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"%C2%BFQue_es_VARBINARY\"><\/span>What is <code>VARBINARY<\/code>?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><code>VARBINARY<\/code> is a data type in MySQL designed to store binary data, that is, data that does not necessarily make up readable or standard characters. Unlike <code>BINARY<\/code>, which stores fixed length bytes, <code>VARBINARY<\/code> provides the ability to store variable length data up to a maximum specified when creating the column in the database.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Ejemplo_basico_de_creacion_de_una_columna_VARBINARY\"><\/span>Basic example of creating a column <code>VARBINARY<\/code><span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Imagine that you need to store scanned images or documents in your database. A field <code>VARBINARY<\/code> could be an excellent option.
