Hello,
I am new to PostgreSQL and want to use the IF-THEN; LOOP
statements in my SQL command file. Thus I may use psql -f cfile
to exceute.
However I always got syntax error on if/for in psql. For
example:
RDM=# for i in 1 .. 10 loop
RDM-# select "test"
RDM-# end loop;
ERROR: syntax error at or near "for" at character 1
LINE 1: for i in 1 .. 10 loop
RDM=# if exits ( select * from testtable)
RDM-# then
RDM-# select "TEST"
RDM-# ;
ERROR: syntax error at or near "if" at character 1
LINE 1: if exits ( select * from testtable) ^
Can someone tell me how to use if/for in psql? The document
shows the control structures in the PL/pgSQL section. Must I use
if/for inside some procedure/function?
Thanks a lot.
Jay
