can we see the original statement ?
can you combine the 2 statements to produce the necessary cursor
OPEN curs1 FOR EXECUTE 'SELECT * FROM ' || quote_ident($1);

> Hi,

> I have a problem when upgrading from 8.2.4 to 8.3/8.4 using ecpg with a prepare statement:
>
> EXEC SQL PREPARE execquery FROM :stmt; line = __LINE__;
> EXEC SQL AT :_thisDbConn DECLARE execcurs CURSOR FOR execquery; line = __LINE__;
> EXEC SQL AT :_thisDbConn OPEN execcurs; line = __LINE__;
> EXEC SQL ALLOCATE DESCRIPTOR execdesc; line = __LINE__;

> I get an "SQL error: invalid statement name "(null)" on line ##" (3rd line above) on the OPEN cursor statement. I have been digging a little in the ecpg output and noticed that the format of the ECPGprepare() function call has changed between 8.2.4 and 8.3++. Also the ecpg library has changed version libecpg.so.5 -> libecpg.so.6.

> I am compiling my program on an (older) system with 8.2.4 installed and I need have my program running on a production system running 8.3.5 or higher. This seems to work fine, but for other reasons I wanted to upgrade my "compile system" with 8.3.5 and this started to give me the error mentioned above.

> libpq.so.5 => /usr/local/Packages/pgsql-8.3.5/lib/libpq.so.5 (0xb7ebc000)

> It seems to me that somehow the prepare statement (first line above) is compiled into a ECPGprepare() call with 5 parameters, but using a library function with only 3 parameters, even though it points to the libecpg.so.6, which includes code having the 5 parameter ECPGprepare() function.
