Problem of creating geometry column (linestring) - Mailing list pgsql-novice

Dear all,
     I have a problem on creating geometry column about linestring.
     In my table (name is pipe), it has 4 coordinates (x1 y1 x2 y2 x3 y3 x4
y4). I want to use them to form lines in geometry column (name is
pipe_geom).
     In sql I type:
SELECT AddGeometryColumn( 'public', 'pipe', 'pipe_geom', 4269, 'LINESTRING',
2 );
UPDATE pipe
SET pipe_geom = GeomertyFromText('LINESTRING(' ||x1 ,y1 || ', '|| x2 ,
y2||',' || x3 , y3||',' || x4 ,y4|| ')', 4269)

But error occurs:
ERROR:  function geomertyfromtext(text, text, text, text, text, integer)
does not exist
LINE 3: SET pipe_geom = GeomertyFromText('LINESTRING(' ||sdo_x1 ,sdo...

     I also try:
SELECT AddGeometryColumn( 'public', 'pipe', 'pipe_geom', 4269, 'LINESTRING',
2 );
UPDATE pipe
SET pipe_geom = LineFromText('LINESTRING(x1 y1,  x2 y2, x3 y3,x4 ,y4 )',
4269)
which error also appears:
ERROR:  parse error - invalid geometry
HINT:  "LINESTRING(" <-- parse error at position 11 within geometry

     I just find example of creating POINT geometry field but have no idea
about how to generate geometry column of linestrings. I hope someone could
help me.

Regards,
Newperson
