i have web page 2 text fields , drop down st_contains , st_intersects , submit button on click should display state lies in country or not.

select c.cid  country c, state s  st_contains('polygon ((1 1,1 4,4 4,4 1,1 1))', 'polygon ((2 2,2 3, 3 3, 3 2, 2 2))')  

the above works selects rows cross join in both table , not 1 c.cid.

select c.cid country c, state s  st_contains( 01030000000100000005000000000000000000f03f000000000000f03f000000000000f03f0000000000001040000000000000104000000000000010400000000000001040000000000000f03f000000000000f03f000000000000f03f, 010300000001000000050000000000000000000040000000000000004000000000000000400000000000000840000000000000084000000000000008400000000000000840000000000000004000000000000000400000000000000040) 

if query error returned

this 1 being executed in php page wherein have written code

may know going wrong.

you there, missing quotes:

select c.cid country c, state s  st_contains( '01030000000100000005000000000000000000f03f000000000000f03f000000000000f03f0000000000001040000000000000104000000000000010400000000000001040000000000000f03f000000000000f03f000000000000f03f', '010300000001000000050000000000000000000040000000000000004000000000000000400000000000000840000000000000084000000000000008400000000000000840000000000000004000000000000000400000000000000040') 

the 'weird' geometry because postgres transforms polygon geometry. can transform them text again using st_astext()

select st_astext( state1 ) state;
