问题 I have an html form that users input data into that saves the values in two MySQL tables, invoices and lineitems. When the "save" button is clicked, these values are inserted as a new row in invoices and lineitems. The page refreshes to display the same form, but with the user-inputted values saved in the input fields. The webpage has multiply 'lineitems' the user can create. This data gets saved to the lineitems table. Each invoice row has a unique id that gets added to each lineitem the

问题 I'm still new and some of the right coding practices escape me. Documentation on this particular situation is weak, so I would like to get some advice/suggestions from you experts :) on the following. I have an API that allows users to update 2 tables in one call. One is a SUMMARY table and the other is a DETAIL table with an FK to the SUMMARY table. What I have my code doing is I do an UPSERT (insert/update) to the SUMMARY table, grab the insert_id and then delete the records from the DETAIL

问题 In Hibernate, you can use @SQLInsert to define a custom insert query. Hibernate is using prepared statements, so you just need to provide the ? as placeholder, like this: INSERT INTO table (colA, colB) VALUES (?,?) On a duplicate key for colA , I want colB to be updated with the new value, so i tried INSERT INTO table (colA, colB) VALUES (?,?) ON DUPLICATE KEY UPDATE colB = ? - This however throws the error that no third parameter is given. ( No value specified for parameter 3 ) How is the

问题 I've been messing about with this code for a few hours now and can't work out why it's not working. It's a profile update php page that is passed through JQuery and all seems to be fine except for it actually updating into the table. Here is the code I'm using: session_start(); include("db-connect.php");//Contains $con $get_user_sql = "SELECT * FROM members WHERE username = '$user_username'"; $get_user_res = mysqli_query($con, $get_user_sql); while($user = mysqli_fetch_array($get_user_res)){

问题 Ok so according to Microsoft docs the OLE DB Command Transformation in SSIS does this The OLE DB Command transformation runs an SQL statement for each row in a data flow. For example, you can run an SQL statement that inserts, updates, or deletes rows in a database table.

问题 I'm writing a Scala web application that use MongoDB as database and ReactiveMongo as driver. I've a collection named recommendation.correlation in which I saved the correlation between a product and a category. A document has the following form: { "_id" : ObjectId("544f76ea4b7f7e3f6e2db224"), "category" : "c1", "attribute" : "c3:p1", "value" : { "average" : 0, "weight" : 3 } } Now I'm writing a method as following: def calculateCorrelation: Future[Boolean] = { def calculate(category: String,

问题 I want to execute a complex upsert, made by the following elements: query on a field f by regex update of the same field f (that is specified in the query object too) Like this: db.coll.update({ prop: /valueprop/i } , { $addToSet:{ prop:'a value' } } , true, false) My expectation would be that if the document does not exist in the collection it is inserted with prop field equals to 'a value'; in other words it should insert a document with value of prop field that is the one specified in the

问题 Good day. I have 3 tables: tblWarehouseProducts : ProductID ProductName ProductCode Quantity tblBranchProducts : ProductID ProductCode ProductCode Quantity Location tblStockMoves : ProductID DestinationLocation Quantity ReferenceNumber Basically, the process is that Branch X requests a product from Warehouse Y. Warehouse Y then creates a request order(called a Stock Move ) and stores the request in tblStockMove . Say for this case, we have a Stock Move with Reference Number XYZ: REFERENCE NO.
