Join them; it only takes a minute: Sign up date_trunc org.postgresql.util.PSQLException: ERROR: syntax error at or near “$1” up vote 5 down vote favorite 1 I get this error while running this Java/JDBC code.

Do you really need to use timestamp casts and date_trunc when you already have dates? PostgreSQL uses numbered placeholders natively ($1, $2, ...) so the ? placeholders are presumably converted to numbered placeholders internally, hence the $2 in the error message. –mu is too short Feb 4 '14 at 2:39 @mu is too short: ok

Postgres Syntax Error At End Of Input
query using .query(string, [value...], fn) gives me this error, even with the appropriate number of values, did the api change or something? Even simple stuff like: client.query('create user $1 with password \'Something1\'', ['tobi'], function(err){ if (err) throw http://stackoverflow.com/questions/21540527/date-trunc-org-postgresql-util-psqlexception-error-syntax-error-at-or-near-1 err; console.log('created'); }); I'm probably doing something obvious wrong :D lalitkapoor commented Mar 14, 2014 @visionmedia I don't think prepared statements can be used with the create user command (or similar). I'll see if I can find documentation to back this up. lalitkapoor commented Mar 14, 2014 I can't find anything specifically to back that up from docs -- so maybe I'm wrong 😦. I do see some people who've tried to do that https://github.com/brianc/node-postgres/issues/539 and have had experienced the same error (in java): http://www.postgresql.org/message-id/925094a20608222109s438a5b41g2886f41e9ddf7417@mail.gmail.com On another note if you want to do a quick check to see if query is work like you'd expect you could try the following (from the readme): client.query('SELECT $1::int AS numbor', ['1'], function(err, result) { if (err) throw err; console.log(result.rows[0].numbor); }); lalitkapoor commented Mar 14, 2014 Looks like I'm not able to prepare the statement using the prepare command in the psql shell (9.3): PREPARE cu (text) AS CREATE USER $1 WITH PASSWORD 'something'; ERROR: syntax error at or near "CREATE" tj commented Mar 14, 2014 Ah I see, I thought the injection escaping was done by this library for .query() lalitkapoor commented Mar 15, 2014 Using .query with arguments string, [value...], fn will generate a prepared statement if I'm not mistaken. prepared statements have several benefits include performance enhancements - via cached query planning and also security - injection escaping. So the way you used the query method was just fine :) Unfortunately it seems prepared statements can't be used with the create command. :/ So you'll want to do some injection escaping on your own, build the query string, and then just pass string, fn as the arguments to query. Hope that helps clarify things :) lalitkapoor commented Mar 15, 2014 More details on how sql injection is handle

On the safe side I would like to prevent SQL injection attacks by parameterizing the SET ROLE statement. My approach in Groovy (which uses JDBC) was: def sql = Sql.newInstance('jdbc:postgresql:mydb', 'mydbweb', 'mydbwebpass', 'org.postgresql.Driver') sql.execute 'SET ROLE ?', user but this generates a syntax error. The documentation says SET ROLE can take a string literal, but I'm just not clear how I can validly pass it one. Any suggestions? postgresql jdbc parameter sql-injection share|improve this question asked Oct 3 '14 at 22:31 beldaz 785413 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted Based on a simple test case I just wrote: @Test public void test() throws SQLException { PreparedStatement ps = conn.prepareStatement("SET ROLE ?"); ps.setString(1, "someuser"); ps.executeUpdate(); } I think the error you refer to is probably: org.postgresql.util.PSQLException: ERROR: syntax error at or near "$1" Position: 10 at org.postgresql.core.v3.QueryExecutorImpl.receiveErrorResponse(QueryExecutorImpl.java:2245) at org.postgresql.core.v3.QueryExecutorImpl.processResults(QueryExecutorImpl.java:1974) at org.postgresql.core.v3.QueryExecutorImpl.execute(QueryExecutorImpl.java:254) at org.postgresql.jdbc2.AbstractJdbc2Statement.execute(AbstractJdbc2Statement.java:565) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeWithFlags(AbstractJdbc2Statement.java:420) at org.postgresql.jdbc2.AbstractJdbc2Statement.executeUpdate(AbstractJdbc2Statement.java:366) ....
