I need some help to understand monetdb kernel/sql structure.
Please, provide example code/paper or link for follow situation:
I have a table (SQL), and I want to change structure of it
(add/drop/rename/order column). I know, I can do it with SQL,
but I need to view examples in MAL or C.
I want to write function like this:
int add_column(str schemaName, str tableName, str newColumnName)
// return 1 if column successfully created
Before posting this message I saw the source code of SQL kernel
and found some functions like sys_drop_column,
and others. But, I don't know how to execute these functions from
my own user defined C/MAL function.
