Why can't I update more than one column at the same time using With keyword?

由 大城市里の小女人 提交于 2019-12-08 18:58:11
问题 I have an update statement shown below that works fine, I used a with statement in the subquery to greatly improve performance but for some reason I'm not allowed to add an additional column from the same table to update. Works: UPDATE Table_A SET (Col_One) = (WITH OneValue AS (SELECT DISTINCT t.Col_One FROM Table_Two t, Table_A a WHERE t.id = a.New_Id)) SELECT Col_One FROM OneValue); What I'd like to do is just include another column to update also from table_two like this UPDATE Table_A SET

What is the difference between MOD and REMAINDER in oracle?

由 [亡魂溺海] 提交于 2019-12-08 18:56:56
问题 Although both the functions perform the same operation, even they produce same o/p, what is basic difference between these two? Is there any performance related difference, if yes, then which one is better? Thanks 回答1: The documentation is pretty clear on the difference: NOTE The REMAINDER function uses the round function in its formula, whereas the MOD function uses the floor function in its formula. In other words, when the arguments are positive integers, the mod function returns a

问题 I'm currently working with Java Stored Procedures in Oracle and am seeing some strange behaviour when attempting to get a connection within my Java code. My Java is packaged up into a jar file and then deployed into Oracle using the loadjava command line utility. A package is then created in the database which maps each method in a designated Java class to a PL/SQL function via call specifications. Some of the columns which I'm working with are CLOB s. In the Java I attempt to extract the

SPOOL returns empty files when trying to export from SQL Developer

由 旧时模样 提交于 2019-12-08 16:57:01
问题 I have a series of queries that I want to output to .csv files. The only tool I have to query the database is SQL Developer. I could run each query and then use the Export dialogue in SQL Developer to write them to files, but that's cumbersome, particularly when this needs to be done for multiple files every day. This works for some people Directly export a query to CSV using SQL Developer But it doesn't work for me. For example, if I try spool "C:\Users\james.foreman\Downloads\Temp\myfile

问题 How to pass a datatable or dataset from C# to the stored procedure in Oracle 回答1: You can not directly. However there are several approaches : Transform your datatable/dataset to a single XML string or blob and use it as a parameter for a stored procedure. Use temporary tables to store your datatable/dataset content, so a stored procedure can process them. 回答2: If you have a dataset or a datatable that you want to insert into ORACLE, you can create an ORACLE data adapter. Then you create a
