The problem is that when I have a table in R which doesn't exist in PostgreSQL, I cannot perform SQL Codes on it.</p> <p>Sample Table s_2 the data format is not data frame and temp is float and DateeTIMEE is timestamps:</p> <pre><code> temp DateeTIMEE 1 -1.64 2007-09-29 00:01:09 2 -1.76 2007-09-29 00:03:09 3 -1.83 2007-09-29 00:05:09 4 -1.86 2007-09-29 00:07:09 5 -1.94 2007-09-29 00:09:09 6 -1.87 2007-09-29 00:11:09 7 -1.87 2007-09-29 00:13:09 8 -1.80 2007-09-29 00:15:09 9 -1.64 2007-09-29 00:17:09 10 -1.60 2007-09-29 00:19:09 11 -1.90 2007-09-29 00:21:09 12 -2.08 2007-09-29 00:23:09 13 -1.94 2007-09-29 00:25:09 14 -2.12 2007-09-29 00:27:09 15 -1.87 2007-09-29 00:29:09 16 -2.18 2007-09-29 00:31:09 17 -1.98 2007-09-29 00:33:09 18 -1.73 2007-09-29 00:35:09 19 -1.84 2007-09-29 00:37:09 20 -2.04 2007-09-29 00:39:09 21 -1.86 2007-09-29 00:41:09 22 -1.94 2007-09-29 00:43:09 23 -1.77 2007-09-29 00:45:09 24 -1.78 2007-09-29 00:47:09 25 -1.50 2007-09-29 00:49:09 26 -1.46 2007-09-29 00:51:09 27 -1.72 2007-09-29 00:53:09 28 -1.67 2007-09-29 00:55:09 29 -1.56 2007-09-29 00:57:09 30 -1.69 2007-09-29 00:59:09 31 -1.97 2007-09-29 01:01:09 32 -1.79 2007-09-29 01:03:09 33 -1.79 2007-09-29 01:05:09 34 -1.84 2007-09-29 01:07:09 35 -1.91 2007-09-29 01:09:09 36 -1.87 2007-09-29 01:11:09 37 -1.98 2007-09-29 01:13:09 38 -1.83 2007-09-29 01:15:09 39 -1.88 2007-09-29 01:17:09 40 -1.88 2007-09-29 01:19:09 </code></pre> <p>I have tries following code:</p> <pre><code>library(sqldf) sqldf("select * from s_2 where temp &gt; -1 ") </code></pre> <p>but I came up with this error:</p> <pre><code> Error in postgresqlNewConnection(drv, ...) : RS-DBI driver: (could not connect postgres@localhost on dbname "test" ) Error in !dbPreExists : invalid argument type. </code></pre> <p>Moreover, could I use table s_2 in this syntax while it is a temporary variable in R and doesn't exist in db?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
