To keep it simple, but to also show several different MySQL data types, I created the following MySQL example database table:Ī few of these MySQL fields are a little contrived, but I wanted to show several different data types in one table, so this is what I came up with. The first thing we’ll need is an example MySQL database table. (That being said, you can learn more about the Java Statement class in this Using SQL INSERT with Java Statement tutorial if you’re interested.) An example MySQL database table As the question implies, you can use the Java Statement class to issue a MySQL INSERT statement, but the Java PreparedStatement class provides a much better way to insert data into a MySQL database table. In this tutorial, we have shown you how to manage MySQL BLOB data, including inserting, updating, and querying blob.Java MySQL INSERT example: Can you share a Java MySQL INSERT example, specifically using a Java PreparedStatement object? You can download the source code of this tutorial via the following link: To replace the PDF file with the GIF image file, you use the updateBlob() method as follows: $blobObj->updateBlob( 2, 'images/php-mysql-blob.gif', "image/gif") Then, we can select the PDF data and render it in the web browser as follows: $a = $blobObj->selectBlob( 2) Įcho $a Code language: PHP ( php ) $blobObj->insertBlob( 'pdf/php-mysql-blob.pdf', "application/pdf") Code language: PHP ( php ) The following code inserts the content of the pdf/php-mysql-blob.pdf PDF file into the BLOB column: $blobObj = new BlobDemo() ![]() Then, we can select the BLOB data and display it as a GIF image: $a = $blobObj->selectBlob( 1) Įcho $a Code language: PHP ( php ) PHP MySQL BLOB with PDF files $blobObj->insertBlob( 'images/php-mysql-blob.gif', "image/gif") Code language: PHP ( php ) PHP MySQL BLOB with image filesįirst, we insert binary data from the images/php-mysql-blob.gif file into the BLOB column of the files table as follows: $blobObj = new BlobDemo() In the following examples, we will use the BlobDemo class to save a GIF image and a PDF file into the BLOB column of the files table. */ public function insertBlob ($filePath, $mime) Code language: PHP ( php ) PHP MySQL BLOB examples See the following insertBlob() method: /** Third, bind the file handle to the prepared statement using the bindParam() method and call the execute() method to execute the query. ![]()
