Cannot simply use PostgreSQL table name (“relation does not exist”)

Question

I\'m trying to run the following PHP script to do a simple database query:

$db_host = \"localhost\";
$db_name = \"showfinder\";
$username = \"user\";
$passwo         


        

Answer 1

Easiest workaround is Just change the table name and all column names to lowercase and your issue will be resolved.

For example:

• Change Table_Name to table_name and
• Change ColumnName to columnname

Answer 2

You have to add the schema first e.g.

SELECT * FROM place.user_place;

If you don't want to add that in all queries then try this:

SET search_path TO place;

Now it will works:

SELECT * FROM user_place;

Answer 3

I had a similar problem on OSX but tried to play around with double and single quotes. For your case, you could try something like this

$query = 'SELECT * FROM "sf_bands"'; // NOTE: double quotes on "sf_Bands"

Answer 4

I had problems with this and this is the story (sad but true) :

1. If your table name is all lower case like : accounts you can use: select * from AcCounTs and it will work fine

2. If your table name is all lower case like : accounts The following will fail: select * from "AcCounTs"

3. If your table name is mixed case like : Accounts The following will fail: select * from accounts

4. If your table name is mixed case like : Accounts The following will work OK: select * from "Accounts"

I dont like remembering useless stuff like this but you have to ;)

Answer 5

If a table name contains underscores or upper case, you need to surround it in double-quotes.

SELECT * from "Table_Name";

Answer 6

Put the dbname parameter in your connection string. It works for me while everything else failed.

Also when doing the select, specify the your_schema.your_table like this:

select * from my_schema.your_table
