Hi,
Is the name of the table important in psql... because the following
create table command doesn't create any table in the database but the
next sql command with a different table name creates the table.
Is there any table name convention in postgres.
create table IL18R---_PGA_SNPs666 (contig char(10),contig_pos
char(10),read_pos char(10),chromat char(30),sample char(30),allele1
char(20),allele2 char(20),ref_pos char(10),ref_sample char(10),tag
char(100),source char(10));
following command works well...
create table MD1_PGA_SNPs666 (contig char(10),contig_pos
char(10),read_pos char(10),chromat char(30),sample char(30),allele1
char(20),allele2 char(20),ref_pos char(10),ref_sample char(10),tag
char(100),source char(10));
thanks
Prakash

I believe the hyphen "-" character is not allowed in a table name.
Only letters, numbers, underscore "_".

I believe - isn't a valid unquoted identifier character.
You can either do "IL18R---_PGA_SNPs666" and always quote the name
or don't use - characters.
I think only letters _ and numbers can be used unquoted (and numbers
can't start), but I haven't checked.

I think you can probably quote the name to have it work:
create table "IL18R---_PGA_SNPs666" (contig cha...
