I need to append data to my BLOB field, how can I do this using an UPDATE command? What i am asking is; is it possible to concatenate blob data so that i can eventually set it to a field like UPDATE BLOB_table SET BLOB_field = BLOB_field + BLOB_data I tried using DBMS_LOB.APPEND but it does not return a value; so i created a function which gives me an error of "invalid LOB locator specified" CREATE OR REPLACE FUNCTION MAKESS.CONCAT_BLOB(A in BLOB,B in BLOB) RETURN BLOB IS C BLOB; BEGIN DBMS_LOB.APPEND(c,A); DBMS_LOB.APPEND(c,B); RETURN c; END; / You need to create a temporary blob with DBMS

I wanna store an entity(a String + an image) in PostgresQL using Spring MVC and Hibernate Here is my table. The image is supposed to be the type of oid. CREATE TABLE document ( name character varying(200), id serial NOT NULL, content oid, // that should be the image CONSTRAINT document_pkey PRIMARY KEY (id ) ) WITH ( OIDS=FALSE ); Here is the entity that I want to store. @Entity @Table(name = "document") public class Document { @Id @GeneratedValue(strategy = GenerationType.IDENTITY) @Column(name = "id") private Long id; @Column(name = "name") private String name; @Column(name="content")

I followed a blob detection example (using cv2.SimpleBlobDetector ) and successfully detected the blobs in my binary image. But then I don't know how to extract the coordinates and area of the keypoints. Here are the code for the blob detections: # I skipped the parameter setting part. blobParams = cv2.SimpleBlobDetector_Params() blobVer = (cv2.__version__).split('.') if int(blobVer[0]) < 3: detector = cv2.SimpleBlobDetector(blobParams) else: detector = cv2.SimpleBlobDetector_create(blobParams) # Detect Blobs keypoints_black = detector.detect(255-black_blob) trans_blobs = cv2.drawKeypoints

I am trying to display a binary file using the method suggested in this post AngularJS: Display blob (.pdf) in an angular app . This is working nicely in Chrome and FF, but IE 11 is giving me "Error: Access Denied". Does anyone know if it has something to do with the Blob object and can point me in the right direction? Here is my js code: $http.get(baseUrl + apiUrl, { responseType: 'arraybuffer' }) .success(function (response) { var file = new Blob([response], { type: 'application/pdf' }); var fileURL = URL.createObjectURL(file); $scope.pdfContent = $sce.trustAsResourceUrl(fileURL); }) .error

I have an azure function which is triggered by a file being put into blob storage and I was wondering how (if possible) to get the name of the blob (file) which triggered the function, I have tried doing: fileObject=os.environ['inputBlob'] message = "Python script processed input blob'{0}'".format(fileObject.fileName) and fileObject=os.environ['inputBlob'] message = "Python script processed input blob'{0}'".format(fileObject.name) but neither of these worked, they both resulted in errors. Can I get some help with this or some suggesstions? Thanks The blob name can be captured via the Function

function getReader(response){ return new Promise(function(resolve,reject){ response.blob().then( blob => { const reader = new FileReader(); reader.addEventListener("loadend", function() { resolve(reader.result) }); reader.readAsDataURL(blob); }) }) } async function getFileObjfun (response){ return await getReader(response); } 在effects中设置一个转换函数 yield调用上边转换 *getFileObj({payload},{call,put}){ const data = yield call(getFileObjfun,payload); // console.log(data,"xxxx") yield put({ type: 'savePDf', payload:data }) }, 来源： https://www.cnblogs.com/chengyunshen/p/11811179.html
