Can we use variable and temporary tables in MySQL data flow ? Something similar to storeprocedure?
Here is the problem that i am currently facing.
I need to Alter table column name at run time dynamically being based on some dataset mapping. Is there a way I could use variable, temporary table or store procedure in MySQL Data Flow so that i can create a dynamic ALTER statement and execute it?
Following is what I am trying to get done.
Declare @sql VARCHAR(MAX)
DECLARE @sql1 varchar(max)
declare @columnname varchar(400) = 'columnName1'
SET @sql = 'alter table tablename rename column "oldcolname" to "
'+ @columnname +'"'
EXEC(@sql)
