问题 I should probably be able to find an answer to this but my Google-fu is weak today. When I have the same stored proc called multiple times by a web app, do the calls queue up or do they run independently? 回答1: Depends on the isolation level of what the stored procedure is doing.

问题 I have a procedure to insert values into one table and update rows of another table. The procedure compiled without any errors. If I manually call it within PL/SQL codes, the tables are updated. CREATE OR REPLACE PROCEDURE payment_update (bId IN number, pType IN varchar2, pAmt IN number ) AS BEGIN INSERT INTO payment VALUES (PID_SEQ.NEXTVAL, bId, pType, (SELECT CURRENT_DATE FROM DUAL), pAmt); UPDATE booking SET payment_status = 'FP', paid = pAmt WHERE booking_id = bId; END; / I am trying to

问题 I've created a stored procedure to return a value for row count of any table I pass in as an "IN" parameter, and output that rowcount to an OUT parameter PROCEDURE `GetCount`(in tblname varchar(255), out rowcount int) BEGIN SET @sql_text1 = concat('SELECT COUNT(*) FROM ',tblname); SET @sql_text2 = concat(@sql_text1,' INTO '); SET @sql_final = concat(@sql_text2, rowcount); PREPARE stmt1 FROM @sql_text1; EXECUTE stmt1; DEALLOCATE PREPARE stmt1; END when I open a query window in MySQL workbench

问题 I have an oracle function which has an in parameter which is of rowtype of a table, from a select statement i need to pass the current row to this function so that it does some processing and returns a value. Is there a pseudo variable that can be used within the context of a select statement something equivalent to a old and new in trigger. I would like to do something like select *,function1(rowtype) from table1 I want to avoid passing multiple parameters, so the question should be seen in

问题 I know the preferred method for returning scalar values from stored procs is either using RETURN or an OUTPUT parameter. But lets say that I have a stored proc that returns the value using a select statement: CREATE PROC spReturnNumber AS SELECT 1 Is it possible to get this value from within another stored proc? CREATE PROC spCheckNumber AS EXEC spReturnNumber -- <-- get the return value here? Clarification: I need a solution that doesn't require using an OUTPUT parameter, or using RETURN to
