Problem using start transaction in nested transactions.

["Sri" <asrinivas@xxxxxxxxxxxx>]

Hi All,

 

I have a small problem in using nested transactions while working on Postgres 8.0.

 

Ex: I have a function A() which in turn calls functions b() and c() , if i want commit something in b or c. i have to use

 

start transaction read write;

-- set of sql statements and then say commit.

commit;

 

but this is not working it is showing the the following error near start transaction read write

" ERROR:  SPI_execute_plan failed executing query "start transaction read write": SPI_ERROR_TRANSACTION ";

 

or

 

 if i use only commit with out the start transaction command it throwing the runtime error

as

 

 

" ERROR:  SPI_execute_plan failed executing query "commit": SPI_ERROR_TRANSACTION ";

  

 

Can any one send me an example of how to use the start transaction or how to commit an nested transaction.

 

Thanks in advance.

 

 

Thanks & Regards,

Sri
