Can you tell me why I get "Can't use query methods that take a query string on a PreparedStatement."?
Try doing:
pStmt.executeQuery()
instead of
pStmt.executeQuery(qry)
as discussed in this question

I keep hitting an error "Can't use query methods that take a query string on a PreparedStatement." when trying to debug the following code & SQL Select query. (Postgres 9.4, jdk 1.8) Maybe I'm blind and it's a simple type, but I could use some help.
My Console Ouput:
SELECT rowid, firstname, lastname, prefname, email1, email2, email3, type, status, preflang, mbrappid, deviceid, mbrstatus, mbrtype, mbrcat, pr_phonevoice FROM qbirt.person WHERE pr_sms = 47 ORDER BY lastupdt DESC
E R R O R JDBC Prep'd Stmt error on Primary Phone FKey... Phone FKey: 47
SQLException: Can't use query methods that take a query string on a PreparedStatement. SQLState: 42809 VendorError: 0 org.postgresql.util.PSQLException: Can't use query methods that take a query string on a PreparedStatement. at org.postgresql.jdbc.PgPreparedStatement.executeQuery(PgPreparedStatement.java:102) at solutions.demand.qbirt.Person.findMember(Person.java:762)`
Portion of code:
if (!foundMbr && foundPhoneID > 0) { if (QbirtUtils.verbose) { System.out.println("Querying Person by FK ID for phones: " + foundPhoneID + "\n"); } if (mode.equals(pMode.SMS)) { qry = "SELECT rowid, firstname, lastname, prefname, email1, email2, email3, type, " + "status, preflang, mbrappid, deviceid, mbrstatus, mbrtype, mbrcat, pr_phonevoice " + "FROM qbirt.person " + "WHERE pr_sms = ? " + "ORDER BY lastupdt DESC;"; } else { if (mode.equals(pMode.VOICE)) { qry = "SELECT rowid, firstname, lastname, prefname, email1, email2, email3, type, " + "status, preflang, mbrappid, deviceid, mbrstatus, mbrtype, mbrcat, pr_phonevoice " + "FROM qbirt.person " + "WHERE pr_phonevoice = ? " + "ORDER BY lastupdt DESC;"; } else { if (mode.equals(pMode.PHONE)) { qry = "SELECT DISTINCT ON (rowid) rowid, firstname, lastname, prefname, email1, email2, email3, type, " + "status, preflang, mbrappid, deviceid, mbrstatus, mbrtype, mbrcat, pr_phonevoice " + "FROM qbirt.person " + "WHERE (pr_sms = ? OR pr_phonevoice = ?) " + "ORDER BY lastupdt DESC, rowid DESC;"; } } } try { PreparedStatement pStmt = conn.prepareStatement(qry); pStmt.setInt(1, foundPhoneID); if (mode.equals(pMode.PHONE)) { pStmt.setInt(2, foundPhoneID); } System.out.println(pStmt.toString()); ResultSet rs = pStmt.executeQuery(qry); <-------
I have confirmed that the fields contain the following values:
foundMbr
= false,foundPhoneID
= 47,mode
= SMS, and thatqry = "SELECT rowid, firstname, lastname, prefname, email1, email2, email3, type, status, preflang, mbrappid, deviceid, mbrstatus, mbrtype, mbrcat, pr_phonevoice FROM qbirt.person WHERE pr_sms = ? ORDER BY lastupdt DESC;";
I get the error on the line:
ResultSet rs = pStmt.executeQuery(qry);
As you can see in the console, I have even confirmed that the pStmt is holding the correct binding because I print it out. - That said, it seems to be missing the ending ';'. Not sure why that is because I can see it in the qry string. I assume that is just a quirk of the preparedStatment.
I have also copied this exact SQL into pgAdmin III and successfully executed it manually. Although, I did have to add back the ';'. I use virtually this same code in many other areas without problem.
Could it be that the missing ';'?
Maybe some sort of type mismatch? (foundPhoneID is an int., rowid is a serial/integer, pr_sms is an integer FKey)
Could it be the block of if statements that defines the qry string?TIA!
