Re: id and ID in CREATE TABLE
Re: [SQL] id and ID in CREATE TABLE |

Hello all, It might be not a correct place to post this. I am creating a table from psql. Everything is fine except I got some troubles when trying to create the same table but in a different way and with pgaccess. If I have this sql: CREATE TABLE ttt ( ID int2, name text ); from psql the ID comes into id in the table. The SQL statements work fine then. If I create the same table using pgaccess the table looks like: Table "ttt2" Column | Type | Modifiers --------+----------+----------- ID | smallint | name | text | After this if I INSERT and SELECT something the results are not the same anymore: TEST1=# INSERT INTO ttt2 VALUES (1,'ttttl'); INSERT 17001 1 TEST1=# select * from ttt2; ID | name ----+------- 1 | ttttl (1 row) TEST1=# select ID from ttt2; ERROR: Attribute 'id' not found Can somebody explain me a bit about: 1. As far as I know column names in Tables are not case sensitive. Correct ? So I know if I pickup ID is not a clever idea but for this example it is ok. As well if I have name and Name it should not matter for SQL. 2. Why psql converts from upper case in lower case column name ID ? Like in the first case. 3. How comes that first using psql I cannot create the column name ID but using pgaccess I can ? Is this a bug ? Some ideas ? stefan
