mysql> select * from CT; | CID | MID | REPORT_QUERY | | 1 | 1 | select * from emp; | | 2 | 2 | select * from student; | 2 rows in set (0.00 sec) I want to execute queries in REPORT_QUERY column. DELIMITER // CREATE PROCEDURE TRYct() BEGIN SET @str=(SELECT GROUP_CONCAT(REPORT_QUERY SEPARATOR ' ') FROM CT); PREPARE q from @str; EXECUTE q; END // DELIMITER ; i use this code but it works if there is only one query in my table. if there is two query than it gives an error. ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for

I want to "concatenate" all the "Text"-rows into one single row and get one row as a result. Is this even possible? I use MSSQL Server 2005. Use FOR XML PATH: SELECT [Text]+' ' AS 'text()' FROM _table FOR XML PATH('') Another option - use string concatenation: DECLARE @s nvarchar(max) SELECT @s = ISNULL(@s, '') + t + ' ' FROM _table OPTION (MAXDOP 1) SELECT @s Please note that the latter one isn't guaranteed to work, afaik, officially the behaviour of "@s = @s + ..." for multi-row resultset is undefined. MAXDOP 1 hint is used here to prevent the optimizer from creating a parralel execution

I have looked through a number of solutions to emulating "Group concat" functionality in SQL Server. I wanted to make a more human readable solution though and I can't work out how to do it. I have a view: ParentID | ChildName Which contains the records, for example: 1 | Max 1 | Jessie 2 | Steven 2 | Lucy 2 | Jake 3 | Mark I want to "Group Concat" these to get: 1 | Max and Jessie 2 | Steven, Lucy and Jake 3 | Mark So If there is only 1 child, just return name, if there are more than one, concat the last 2 with an ' and ' and all others with a ', '. I am a bit stuck on how to do this without

Is it possible to concatenate strings with one or more of other group by function like sum, avg, count etc . Say I have the following table Id Name Order Value 1 a 1 100 2 b 2 200 3 c 1 300 4 d 1 100 5 e 2 300 Now if I want the result to be something of this sort Order Name Value Count 1 a,c,d 500 3 2 b,e 500 2 How can i achieve the same using a query on SQL server. Sample table create table t123 (Id int, Name varchar(10), [Order] int, Value int) insert t123 select 1,'a','1',100 union all select 2,'b','2',200 union all select 3,'c','1',300 union all select 4,'d','1',100 union all select 5,'e',

I have the following query which returns the salary of all employees. This work perfectly but I need to collect extra data that I will aggregate into one cell (see Result Set 2). How can I aggregate data into a comma separated list? A little bit like what Sum does, but I need a string in return. SELECT Employee.Id, SUM(Pay) as Salary FROM Employee INNER JOIN PayCheck ON PayCheck.EmployeeId = Employee.Id GROUP BY Employee.Id Result Set 1 Employee.Id Salary ----------------------------------- 1 150 2 250 3 350 I need: Result Set 2 Employee.Id Salary Data -----------------------------------------

I'm using Microsoft SQL Server 2005. I think I need a sub-query. I'm looking for one (1) row per customer, with the AvailableAction field be a concatenation of all the Actions for each customer. use tempdb GO IF DB_ID('myDatabase') IS NOT NULL DROP DATABASE myDatabase go CREATE DATABASE myDatabase GO USE myDatabase GO create table Cust( CustID Int Identity Primary Key, CustName Varchar(255) ) GO INSERT INTO Cust(CustName) values('One') INSERT INTO Cust(CustName) values('Two') GO CREATE TABLE Action( ActionID Int Identity(101,1) Primary Key, ActionName Varchar(128) ) GO INSERT INTO Action

This question have been asked many times in SO but none of the answers is satisfying to my situation. Question 1 Question 2 Question 3 Question 4 I am dealing with a DataObjectVersions table that contains multiple versions for around 1.2 million unique objects (and increasing). I need to concatenate changes from a specific field for each unique object. Right now I am using the solution with the XML Path presented in Q3 but running such a query on this table is a total performance disaster. SQL Server started to retun Data after 19mn. Knowing that this data will be than joined twice, you can
