问题 My goal is to select result from one CTE and insert into other table with another CTE in the same procedure. How to do it? My error is... invalid object name xy. My query is WITH ds ( Select a, b, c from test1 ), xy ( select d, e, f from test2 where (uses conditions from ds) ) Select * from ds (the result set of ds, am exporting this to csv) Insert into AuditTest ( Select * from xy ) 回答1: A CTE is only good for one query, but it looks like you can use a CTE in each query: WITH ds AS ( Select

问题 I created Dynamic Stored procedure for select. I'm going to use this generic query for execute multiple select statement, by passing the parameter. DECLARE DESC_CSR CURSOR WITH HOLD FOR V_SQL; SET V_SELECT = 'SELECT ' || SELECT_FIELDS || ' FROM ' || TABLE_NAME || ' WHERE ' || WHERE_CLAUSE || ' WITH UR'; PREPARE V_SQL FROM V_SELECT; OPEN DESC_CSR; I will pass below values. SELECT_FIELDS = B.COLUMN_A INTO HOST_VAR_A TABLE_NAME = TABLE_A A INNER JOIN TABLE_B B ON A.ROW_ID = B.ROW_ID WHERE_CLAUSE

问题 What is the difference between: CREATE PROCEDURE [dbo].[MyProcedure] @MyArgument INT NULL and CREATE PROCEDURE [dbo].[MyProcedure] @MyArgument INT = NULL I used the first one, and it worked fine in SQL Server 2016. But SQL Server 2012 did not accept it. Both works on SQL Server 2016, and I am using the second one now without problem. But it would be interesting to know the difference. Thanks! 回答1: They don't do the same thing. The second one defines a default value for the case that the

问题 In my project I have to a configure database as soon as registration complete. I have a dump.sql file which I am able to import and create all the required tables from .sql file using this library but my stored procedures are not getting imported in my database. It is a big procedure. Is there a way to create a stored procedure from node.js. I tried this but getting error. Any help would be greatly appreciated. TypeError: StoredProcedures is not a constructor 回答1: Beauty of OSS is that

问题 Working on a legacy solution that uses MyBatis and Oracle's stored procedures for bulk database updates. Current version of Mapper looks similar to this @Mapper public interface MyMapper { void doUpdate(@Param("in") Map<String, List> in, @Param("out") Map<String, List> out); } The idea is to provide a map of lists of the same length with fields values as "in" parameter to use those lists as an arguments to call a stored procedure like this <select id="doUpdate" statementType="CALLABLE"> <!

问题 I have a stored procedure in oracle (which schedules a one-time job to run another procedure, if this is relevant). The job calls another stored procedure which runs for a few minutes, and performs inserts updates and deletes and also uses loops. Now while the long procedure is running, if there is another call for it to run, is it possible to prevent them from executing simultaneously? And even better, to make the second one execute once the previous one has finished, like queue them? 回答1:

问题 I am new in Oracle PL/SQL. I trying to write a procedure where I would first get data from a column in a table and assign to a variable. Then for each row/value in the result, I perform another query and loop through the result of this new query and perform various inserts and updates. After which I would go back to the outer loop and continue the sequence. My attempt is as follows: CREATE OR REPLACE PROCEDURE CMSADMIN.Proc_RFC_UPD_NEW_MRSP IS ecode NUMBER; emesg VARCHAR2(200); cursor y IS

问题 Can i pass table variable as a PARAMETER To a Stored Procedure in MySql 回答1: If you want to pass a table into the stored procedure as parameter - then answer is no. Only scalar values can be passed. The table can be accessed by its name directly; if you want to use that table name to construct and run new query in procedure, then have a look at prepared statements. 回答2: yes TableA: MyId MyNumber 1 5 2 6 3 9 Select myNumber, MyStoredProcedure(MyNumber) from TableA where MyNumber > 5 来源： https:
