Awk Syntax Error Near Line 1 Awk Bailing Out Near Line 1
I get the error pq: syntax error at or near "$1" If I put in the epoch values directly then the query will work and the query works when I try it without any variables i.e. with the query hardcoded. So what is the problem? postgresql go share|improve this question asked Mar 12 '15 at 11:01 robochat 59259 have you tried ? and not $1 –Not_a_Golfer Mar 12 '15 at 11:58 1 It gives the same error (i.e. syntax error at or near "?"). Anyway, I thought that the pq module used $1 ? –robochat Mar 12 '15 at 12:02 hmmm... can you try and make your query a single multi-line string using backticks? Not that I think it would matter but otherwise things seem okay, and it's a better practice in terms of GC pressure and cpu performance anyway. –Not_a_Golfer Mar 12 '15 at 12:13 add a comment| 1 Answer 1 active oldest votes up vote 3 down vote accepted You're right about $1 and ?. The reason why it complains about invalid syntax with $1 is because of type cast. Put it like this: rows, err := db.Query("select time, val

to know. 38.10.1. Variable Substitution When PL/pgSQL prepares a SQL statement or expression for syntax error at or near send at character 1 execution, any PL/pgSQL variable name appearing in the statement or expression is replaced by a parameter symbol, $n. The current value org.postgresql.util.psqlexception: error: syntax error at or near "$1" of the variable is then provided as the value for the parameter whenever the statement or expression is executed. As an example, consider the function CREATE FUNCTION logfunc(logtxt text) RETURNS void AS $$ DECLARE curtime timestamp http://stackoverflow.com/questions/29007972/golang-syntax-error-at-or-near-1-in-postgres := now(); BEGIN INSERT INTO logtable VALUES (logtxt, curtime); END; $$ LANGUAGE plpgsql; The INSERT statement will effectively be processed as PREPARE statement_name(text, timestamp) AS INSERT INTO logtable VALUES ($1, $2); followed on each execution by EXECUTE with the current actual values of the two variables. (Note: here we are speaking of the main SQL engine's EXECUTE command, not PL/pgSQL's EXECUTE.) The substitution mechanism will replace any token that matches a known https://www.postgresql.org/docs/8.3/static/plpgsql-implementation.html variable's name. This poses various traps for the unwary. For example, it is a bad idea to use a variable name that is the same as any table or column name that you need to reference in queries within the function, because what you think is a table or column name will still get replaced. In the above example, suppose that logtable has column names logtxt and logtime, and we try to write the INSERT as INSERT INTO logtable (logtxt, logtime) VALUES (logtxt, curtime); This will be fed to the main SQL parser as INSERT INTO logtable ($1, logtime) VALUES ($1, $2); resulting in a syntax error like this: ERROR: syntax error at or near "$1" LINE 1: INSERT INTO logtable ( $1 , logtime) VALUES ( $1 , $2 ) ^ QUERY: INSERT INTO logtable ( $1 , logtime) VALUES ( $1 , $2 ) CONTEXT: SQL statement in PL/PgSQL function "logfunc2" near line 5 This example is fairly easy to diagnose, since it leads to an obvious syntax error. Much nastier are cases where the substitution is syntactically permissible, since the only symptom may be misbehavior of the function. In one case, a user wrote something like this: DECLARE val text; search_key integer; BEGIN ... FOR val IN SELECT val F
