hi all,
I have a table
privileges (version text, profile text,
readbits bit[], writebits bit[]);
The readbits and writebits is 4000 bits long.
The operation i am trying to do is.
(eg) insert into privileges (version, profile) values ('ver100', 'prf100');
For version ver100 and profile prf100 the readbits and writebits must have all
bits set to 0.
So i wrote a stored procedure which will update the bitsets.
create function testproc(text,text) returns int as '
declare
version alias for $1;
profile alias for $2;
flatbits text;
count int := 0;
begin
flatbits = ''\\\'{'';
-- for inserting the '{ in the array
while count < 4000
loop
flatbits = flatbits||''0,'';
count := count + 1;
end loop;
flatbits = flatbits||''}\\\''';
-- for closing the bit set }'
end;
insert into privileges(version, profile, flatbits, flatbits);
' language 'plpgsql';
When i try to run this as
testdb=# select testproc('ver100', 'prf100');
ERROR: Attribute 'readbits' is of type '_bit' but expression is of type 'text'
You will need to rewrite or cast the expression
Casting the value to bit in stored procedure also doesnt help.
i used
insert into privileges(version, profile, flatbits::bit[], flatbits::bit[]);
ERROR: Cannot case type 'text' to '_bit'
Can anybody help me in this regard.
TIA.

regards,
hari
